TO: Corcoran City Council FROM: Kendra Lindahl, Landform D ATE: February 1, 2018 for the February 15, 2018 Council W ork Session RE: 2040 Comprehensive Plan – Land Use Discussion (city file no. 17-001) 1.Background In 2017, the City initiated the planning process to update the 2030 Comprehensive Plan that was completed in 2011. It was the Council’s direction that no major policy changes were anticipated and this would be an update of the existing plan. 2.Updates to the 2040 Comprehensive Plan As part of the 2040 Comprehensive Plan update, the City has held several meetings with residents, Commissions, and Council to gather feedback and understand community priorities and what has changed since that time. The Council has directed staff to make some changes (transportation, land use, parks, etc.) and those changes have been incorporated into the plan. The City staff team (Landform, Wenck and City Staff) has incorporated the feedback into updated chapters and City Hall Staff has been working hard to create a new document that is more graphically interesting. The document was updated to include more tables and graphic components to make the document easier to read. Interactive links are being developed for the document, making navigation easier (this is not active in the current draft, but will be in the final draft). Staff will be prepared to walk through the key updates at the meeting. 3.Action Items: The goal for the meeting is to provide content edits and direct staff to revise the document for consideration at the March Planning Commission and Parks and Trails meetings. Those drafts will also be provided to the Council for additional review. Feedback from those meetings will be incorporated into a final draft that will be presented at the April 5th Planning Commission Public Hearing for action at the April 26th Council meeting. The document would then be distributed for a 6-month comment period before being submitted to the Metropolitan Council. We are asking the Council to approve the framework of the plan for public review and to provide any suggested changes that should be incorporated. 2040 Comprehensive Plan (city file 17-001) 2 February 15, 2018 Attachments a.

with its rural character. These resources are intrinsic to our quality of life. The 2040 Plan will enable the residents of 2040 Corcoran to continue to share in this defining experience. These visions of 2040 Corcoran will be achieved through the community’s adherence to the following guiding principles: 1. Protection of the natural resources, open space, and rural character that define Corcoran’s quality of life. 2. Creation of opportunities for a thriving Town Center with a range of retail, office, residential, and gathering spaces. 3. Creation of opportunities for expanded employment and tax bases combining commercial, industrial, and business park land uses. 4. Expansion of residential options to achieve life-cycle housing. 5. Support rural residential development in non-urbanized Corcoran in a manner that preserves efficient, future urbanization and protects natural resources while allowing current economic benefit to landowners. regional setting Corcoran is located on the northwestern edge of Hennepin County, and is located 20 miles from downtown Minneapolis. Corcoran has remained generally rural and comprises just under 36 square miles of land. The vast majority of the city is located in the Rush Creek and Elm Creek Watershed systems, with a small area in southwest Corcoran draining into the Pioneer/ Sara Creek watershed, and then emptying into the Crow River. Communities bordering Corcoran include the cities of Maple Grove, Medina, Greenfield, Hanover, and Roger.

The western half of Corcoran is classified by the Metropolitan Council as a “Diversified Rural” area. Diversified Rural communities are defined by the Metropolitan Council as the sparsely developed parts of the region that host the widest variety of farm and non- farm uses. Uses include a mix of limited large-lot residential and clustered housing, agriculture, and facilities and services requiring a rural location. Limited growth is forecasted for these areas, and they are not currently planned for urban development. The Metropolitan Council has adopted a Flexible Development Ordinance for Diversified Rural communities to ensure that development patterns are efficient and cost-effective while also providing opportunities for landowners. Emerging Suburban Edge communities include cities, townships and portions of both that are in the early stages of transitioning into urbanized levels of development. Emerging Suburban Edge communities are expected to plan for forecasted population and household growth at average densities of at least 3-5 units per acre for new development and redevelopment. There are 9,471 acres in the 2040 Metropolitan Urban Service Area (MUSA). This designation allows development of land to occur at urban densities with urban infrastructure of City water, stormwater, and sewer facilities. Diversified Rural communities are home to a variety of farm and nonfarm land uses including very large-lot residential, clustered housing, hobby farms and agricultural uses. Diversified Rural communities are expected to plan for growth not to exceed forecasts and in patterns that do not exceed 4 units per 40 acres, except when as part of open space preservation plan that is consistent with the flexible residential development guidelines outlined in Metropolitan Council policy. In addition, Diversified Rural communities are expected to manage land uses to prevent the premature demand for extension of urban services, and so that existing service levels will meet service needs. Map1-2: Community Designations metroPolitan Planning aCt The Metropolitan Planning Act requires every City in the 7-county metropolitan area to create a 20-year comprehensive plan and update the plan every 10 years. The Metropolitan Council reviews every City’s comprehensive plan to ensure the plan is compatible with regional system plans for sewer, transportation, parks and open space. The City of Corcoran has prepared an updated comprehensive plan that achieves the community’s own vision and goals for the future, while meeting the Metropolitan Council’s regional planning requirements. 2030 Plan The City’s 4th comprehensive plan, the 2030 Plan, was approved in March 2010. The 2030 Plan identified Corcoran as a growing community with a walkable downtown, along with commercial and industrial businesses, housing variety, and natural resources. The 2030 Plan continued to emphasize the importance of Corcoran’s abundance of natural resources and open spaces. 2040 vision statement Corcoran’s 2040 Comprehensive Plan, the 2040 Plan, represents a community-generated update to the 2030 Plan. The update process involved Corcoran residents, the City Council, Planning Commission, and Parks and Trails Commission. The update process included 8 City Council work sessions focused on the Comprehensive Plan components and discussion at multiple City Council meetings. Two community-wide surveys and 3 community engagement sessions were held to identify a vision for Corcoran in the year 2040. This vision is supported by and will be achieved through a series of principles, goals, and policies related to land use and development. The City of Corcoran in 2040 will be a vibrant community, defined by its dynamic Town Center, strong base of commercial and industrial businesses, variety of housing options, and high-value natural resources. The mixed-use Town Center, planned to be northeast of the junction of County Road 116 and County Road 10, will provide the community with a public gathering space as well as retail and job opportunities for residents. Corcoran’s 2040 commercial, industrial, and business park developments will provide both local employment and a stronger, more diverse tax base. Broader housing options in 2040 will ensure a place in our community for first-time homebuyers, growing families, and seniors.

Open space and other high-quality natural resource areas are abundant, and these amenities are highly valued by residents. A remarkable 21 percent of the City’s total land area consists of wetlands (National Wetland Inventory Areas), lakes, and open water, as well as 52 miles of streams. There are also mutliple areas of potential and possible wetlands throughout the City. The City’s 2020 and 2030 Plan included a Natural Resource Inventory (NRI) that identified all of the significant natural resource areas in the community. The NRI also provided recommendations and priorities for the preservation and enhancement of the natural systems. The Natural Resources Chapter of the 2030 Plan incorporated many of the NRI findings and recommendations. Large lot, rural residential single-family homes are the predominant form of housing in Corcoran. A smaller number of suburban-sized lots are located near the downtown and in other select areas. A manufactured home park is located in southeast Corcoran. Residents in Corcoran have identified the need for life-cycle housing in the community, in particular to address the lack of housing opportunities for first-time home buyers and downsizing seniors. Commercial and industrial development in the City is limited, primarily due to the lack of municipal water and sewer services and the absence of major transport corridors. The City supports continuation and expansion of commercial enterprises in the downtown area at County Road 116 and County Road 10. Burschville is a commercial area located in northwest Corcoran, at the intersection of County Roads 10 and 19. Commercial and industrial activities also occur in southwestern Corcoran, at the intersection of Highway 55 and County Road 19. Corcoran has 2 main City facilities. This includes City Hall, which is shared by Administration and the Police Department and is located on County Road 116. The City also has a Public Works facility located on County Road 19 as well as a small auxiliary public work building located on Cain Road (Old Public Works). Corcoran has a City Park with multiple amenities and is located at the intersection of County Road 50 and County Road 10. The City is home to 3 golf courses and Corcoran Lion’s Park, which hosts a multitude of events, including Hamel Rodeo, Corcoran Country Days, tractor pulls, etc. The North Hennepin Pioneer Society owns and maintains a historic single-room school on County Road 10. There are multiple churches and cemeteries in the City. These facility locations a can be viewed on Map 1-4. The City is comprised of a network of different roadways, including State Highway, County Roads, and City Streets. Corcoran is unique in that the City’s local streets are comprised of a nearly equal amount of pavement and gravel. Map 1-5 shows approximately 36 miles of paved roads and 34 miles of gravel roads.

There are no public schools located in Corcoran. One private school, St. John’s Lutheran Church, offers pre-kindergarten through 8th grade education. The Rockford school district owns property in the City. However, it appears unlikely the district will utilize the site for a future school.

According to the American Community Survey, the City’s 2016 median age was 45.4 years, which was higher than the median age of 36.2 years in Hennepin County. Approximately 25 percent of Corcoran’s population was under the age of 18 in 2016, while 10.45 percent (up from 4.5 percent in 2010) of the population was over age 65. Like many cities in the U.S., the City’s median age is expected to increase as the “baby boom” generation enters retirement. Over 52 percent of households are families without children with the average household size of 2.86. See Figure 1- 3: Household Type in Corcoran; Figure 1-4 Average Household Size in Corcoran. natural CharaCteristiCs Corcoran’s abundant, high-quality natural resources and open spaces are the predominant elements of the rural character that define the City. The City’s open spaces consist primarily of farmed areas under active cultivation. Significantly, 47 percent of the City’s land area consists of relatively undisturbed natural resource communities, including upland areas of savanna/pasture, maple/basswood woodlands, and oak forests, as well as wetlands, open water, and streams. Balancing preservation of these features with future growth is a cornerstone of the 2040 Plan. One of the goals of this Plan is to preserve the highest quality natural resources, as identified by the Natural Resource Inventory. The goal places priority on the natural resources patterns in the community in directing future development. The land use plan for the City is shaped by the existing environment. Sensitive natural areas create boundaries for development planning, affect the location of new services and provide buffers between land uses. Existing natural rEsourcEs The areas of Corcoran that are not farmed or have not been developed for residential, public, or commercial uses can be divided into 2 broad categories – Natural Areas and Semi-Natural Areas. The Natural Areas are defined by the existence of native plant communities and the Semi-Natural Areas are defined by areas where original vegetation has largely been replaced by non- native plant species. natural areas At the time of European settlement, northwestern Hennepin County was comprised primarily of maple-basswood forest and mesic oak forest (referred to as Big Woods), with inclusions of wet prairie, marshes, and lakes. Examples of this historic vegetation remain in locations scattered throughout the City, as identified on Map 1-7: Natural Resource Inventory. Some of the best examples of Big Woods remnants are found along both the north and south Rush Creek corridors. Other fragmented native forest remnants can be found in the west central portion of the City.

These forecasts underlie substantially all of the 2040 Plan elements. These forecasts are presented in Figure 1-5: Population and Household Forecasts. The City’s future land use and infrastructure plans were developed to accommodate the 2040 forecasts. This ensures the City has guided enough land and has adequate infrastructure in place to accommodate projected growth. natural resourCe areas -- 47 PerCent 19% Wetlands 2% Open Water 26% Upland Areas Savanna/Pasture, Maple/Basswood woodlands, and Oak Forests 6,700 8,900 11,300 2,500 3,570 4,700 6,700 8,900 11,300 2020 2030 2040 Year POPULATION AND HOUSEHOLD FORECASTS FIGURE 1-5 Sum of POPULATION Sum of HOUSEHOLDS Sum of POPULATION IN HOUSEHOLDS Sources: U.S. Census Bureau Decennial Census, Metropolitan Council Annual Estimates, and Metropolitan Council Draft Copy -- 2/1/2018 12 High-quality wetland areas occur within and adjacent to the Rush Creek corridors and Jubert Lake. The Minnesota County Biological Survey identifies 2 wetland areas to be of state-wide interest.” One is a moderate quality wet meadow community in parts of Sections 34 and 35. While the diversity of the wet meadow has been reduced by ditching, the size of the complex and connections to other large wetlands contribute to its ranking. The second is a moderate quality tamarack swamp in Section 33 that is part of a larger upland-wetland complex and includes Morin Lake. Corcoran is within the southwestern range of the tamarack swamp plant community, making this wetland area rare and unique within the City. semi-natural areas Semi-natural areas are areas of land not subject to active use and that are dominated by vegetation not originally found in those locations. Examples include fallow pasture or crop land that has been retired (old field), degraded wetlands dominated by reed canary grass or other invasive species, and secondary growth or disturbed woodlands, typically dominated by box elder, green ash, and basswood. These areas still offer significant benefits for wildlife and water quality protection. These areas often form important buffers around and connections between higher quality Natural Areas. These Semi- Natural Areas form much of the open space and undeveloped lands within the City. Sites with proximity to high-quality natural resource areas or that tend to assist in the formation of connected natural resource corridors should be considered high priority for restoration. soils The soils of northwestern Hennepin County are predominantly loams, which historically supported mixed hardwood forests, wet prairie, and savanna. These soils are also well-suited for agricultural crops such as corn, soybeans, hays, and pasture lands. Non-draining depressions occur frequently in this portion of northwestern Hennepin County and tend to support hydrophilic vegetation (i.e., wetland plants such as sedges, grasses, rushes, and wetland herbs) and organic soil accumulation. Map 1-8: Hydrologic Soil (See page XX for large size map) WatEr rEsourcEs Water resources define and affect every aspect of the community’s use and enjoyment of the Corcoran natural environment. Surface waters, both protected and non-protected, wetlands, and groundwater all dictate how the community lives, works, and plays. Water is a resource of common interest and importance throughout the community. surfaCe Water The City has a number of surface water resources, including the North Fork of Rush Creek in northwestern Corcoran and Rush Creek in the central and eastern portion of the City. There are also numerous tributary watercourses and ditches, wetlands, and several small named lakes. A portion of the surface water resources are defined as “protected waters.” Protected waters include lakes, rivers, wetlands or other bodies of water meeting standards set by State law. These sites provide public value for recreation, water quality, water supply, wildlife habitat, or are publicly owned. The Minnesota DNR has regulatory authority over protected waters, including issuance and enforcement of permits controlling activities that impact these areas. Map 1-9: Water Resource (See page XX for large size map) The City also has significant areas of FEMA Floodway and Floodplain.

The remaining wells in the City draw water from the Franconia-Ironton-Galesville Aquifer. Hennepin County leads efforts to protect this groundwater supply. The County monitors groundwater elevations and maintains an inventory of contamination sites. Wetlands Wetlands are common throughout Corcoran, covering approximately 19 percent of the City’s land area. An even greater percentage of land is unbuildable due to its proximity to these wetlands. Corcoran’s Wetlands provide a number of valuable services to the community, including natural flood control, cleaning flowing water, recharging groundwater, and creating valuable habitat for wildlife. Wetlands are an aesthetic amenity in many developments and can provide visual and spatial buffers between homes. Nearly all of Corcoran’s wetlands are protected by Minnesota’s Wetland Conservation Act and certain waterways are also affected by Federal regulations. Appropriate permits are required prior to any activities that fill, drain, or otherwise impact regulated wetlands. Map 1-11: Wetlands (See page XX for large size map) Several resources exist to assist in identifying wetlands. The National Wetlands Inventory (NWI) is a national assessment of wetland resources, conducted by the U.S. Fish and Wildlife Service, between 1988 and 1992 within the State of Minnesota. The NWI is useful in giving an estimate of the extent (i.e. approximate geographic location) and type (i.e. system, hydrologic regime and predominant vegetation types) of wetlands within the City. The NWI survey was based strictly on aerial photography reconnaissance and interpretation and may be less accurate than some of the other sources. The City’s Natural Resource Inventory was completed in 2001 with inventories of both upland and wetland communities. Most areas were field- checked and mapped using current aerial photographs. Prior to that, the Hennepin Conservation District (HCD) completed a remote assessment of wetland and potential wetland areas within Hennepin County based on a review of then-current aerial photographs, topography, and hydric soils information. This survey includes potential wetland areas not included in the NWI (altered or restorable) and omits wetlands that have been filled since the completion of the NWI.

PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 43 LAND USE Goal 2: Provide a variety of housing types, styles, densities and choices to meet the housing needs of residents. Policy 1: Provide a mix of housing types to provide for a full continuum of housing opportunities, including continued single-family growth and new opportunities for multiple family and senior housing developments. Policy 2: Provide transitions or buffering from low density and rural residential areas to higher density uses. Policy 3: Ensure that all new housing adheres to the highest standards of planning, design and construction. Goal 3: Create new land use opportunities to expand and diversify the City’s tax base by encouraging new commercial development. Policy 1: Use the Mixed Use land use designation to develop a Town Center similar to that envisioned in the Corcoran Southeast District Plan and Design Guidelines adopted in 2016. These guidelines will be updated to reflect the new transportation policies in this plan. Policy 2: Create performance standards for all commercial areas, including building and signage design guidelines, streetscaping, and inclusion of green space, paths, and sidewalks to connect commercial areas to neighborhoods. Policy 3: Support and promote existing businesses and new businesses that are viable and responsive to the needs of the community. Goal 4: Attract and encourage new light industrial, office-industrial, high tech and professional services and maintain and expand existing businesses in Corcoran. Policy 1: Encourage high-end business park development that attracts medical, technology, and similar industries that provide quality employment and wages. Policy 2: Develop a market plan and strategy aimed at creating an industrial and high-end business park identity that will help recruit business and industry to Corcoran. Policy 3: Create industrial and business park building, signage and landscaping design guidelines that will result in high-quality building and site development. Policy 4: Encourage use of “green”, environmentally-friendly building and site development techniques in new developments through zoning requirements or incentives. Goal 5: Create a unified vision and future for Corcoran by promoting a well- planned community, preventing fragmented development, and addressing the impacts of expanding services and development on natural features and view corridors while providing a balance of land uses with connectivity to all areas of the community. Policy 1: Create a land use plan that provides housing development types and locations required to meet the community’s projected needs. Policy 2: Create a staging plan that supports infrastructure expansion and land use growth plans. Policy 3: Work with neighboring communities to ensure an integrated plan that is consistent with the Metropolitan Council’s requirements and compatible with adjacent jurisdictions. Policy 4: As development proceeds, protect the natural features, slopes and sensitive areas that make Corcoran unique, such as streams, wetlands, lakes, woodlands, natural open space, and local parks. Policy 5: Prepare long-range transportation and infrastructure plans that will direct and support growth and allow the City to financially plan for such growth. Policy 6: Expand the level of community services to keep pace with orderly development. Goal 6: Ensure that zoning and subdivision ordinances are consistent with the intent and specific direction of the land use plan. Policy 1: Ensure that developers are aware of and perform according to the land use plan and all official controls. Policy 2: Encourage creative approaches to land development to support preservation of open space and natural resources. Policy 3: Coordinate plans for housing with plans for Light Industrial, office/ industrial and Commercial areas to balance land uses, serve the quali- ty-of-life needs of the residential areas and foster a positive climate for business, jobs and tax base growth. Policy 4: Ensure compatibility of adjacent land uses. Policy 5: Routinely update the zoning map to conform to the land use map. The 2040 Land Use Plan identifies the location and intensity of anticipated development within the City and establishes a framework in which that development may occur. The 2040 Land Use Plan was developed to support the community vision and guiding principles discussed in Chapter 1. The 2040 Land Use Plan generally retains the land use categories created under the 2030 Plan. The MUSA boundary remains the same except for an expansion of Industrial and Low Density Residential in the southwest part of the City. This 932-acre expansion will allow Corcoran to continue to work with the Metropolitan Council Environmental Services (MCES), Loretto and Medina on the “Maple Plain LS/RF Rehabilitation: Project 8081”, which would provide new facilities to serve Loretto, northwest Medina and southwest Corcoran. Corcoran will see an increased opportunity for development as the Twin Cities metropolitan area continues to grow and communities closer to the core fully develop. Corcoran’s scenic natural resource areas, proximity to rapidly growing neighboring communities, the development of the Highway 55 corridor, and the potential linking of County Road 30 with the future Highway 610 corridor all represent development assets, influences and pressures. The 2040 Plan seeks to create the flexibility to respond to market conditions while guiding land uses that adhere to the community’s vision and guiding principles. The 2040 Land Use and Staging Plans meet the Metropolitan Council forecasts for potential development and provide methods through land use and density to meet the Metropolitan Council’s residential density guidance of 3.0 housing units per net developable acre. As a regional planning organization, the Metropolitan Council’s role is to ensure that regional infrastructure can accommodate Corcoran’s potential growth and growth within the region. Meeting this minimum density requirement ensures that regional infrastructure is used in a cost-effective and efficient manner. goals and PoliCies The community has established the following Goals and Policies to guide residential development in Corcoran. Goal 1: Ensure housing development is compatible with existing and adjacent land uses and has access to key community features, natural features and views of open spaces. Policy 1: Establish development guidelines for appropriate amount of green spaces, viewshed analysis, paths, sidewalks, trails and connections throughout the community. Policy 2: Link residential neighborhoods via trails to City parks, Town Center and other public and commercial areas. Policy 3: Incorporate preservation of natural resources in residential developments. Policy 4: Encourage innovation in subdivision design, such as clustering techniques, to preserve open space or natural features. Policy 5: Undeveloped single-family residential land shall be developed with consideration for surrounding development and in a manner responsive to market needs. PICTURE PLACEHOLDER PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 44 2040 land use and groWth management rElationshiP to MEtroPolitan council thrivE MsP 2040 Plan In addition to guiding Corcoran’s future growth, the community’s 2040 Land Use Plan also relates to growth and development in the region as a whole. As part of the 7-county metropolitan area, Corcoran is expected to absorb its share of the region’s growth. The Comprehensive Plan must demonstrate the City’s capacity to absorb this growth. The Comprehensive Plan must also demonstrate that this growth will be managed to ensure efficient use of the region’s sewer and transportation infrastructure. The Metropolitan Council has developed the following land use policies to guide regional land use and development: Orderly and Efficient Land Use: Align land use, development patterns, and infrastructure to make the best use of public and private investment. Natural Resources Protection: Conserve, restore, and protect the region’s natural resources to ensure availability, support public health, and maintain a high quality of life. Water Sustainability: Conserve, restore, and protect the quality and quantity of the region’s water resources to ensure ongoing availability, support public health, and maintain a high quality of life. Housing Affordability and Choice: Promote housing options to give people in all life stages and of all economic means viable choices for safe, stable, and affordable homes. Access, Mobility, and Transportation Choice: Sustain and improve a multi-modal transportation system to support regional growth, maintain regional economic competitiveness, and provide choices and reliability for the system’s users. Economic Competitiveness: Foster connected land use options to provide businesses and industries with access to materials, markets, and talent. Building in Resilience: Promote sensitive land use and development patterns to achieve Minnesota’s adopted greenhouse gas emissions goals at the regional scale, and to develop local resiliency to the impacts of climate change. The City has prepared a plan that responds to both the community’s goals as well as the Metropolitan Council’s strategies for developing communities, as outlined in Thrive MSP 2040. The 2040 Plan adequately addresses community goals and regional strategies for the following reasons: • The Plan identifies areas of low, medium, mixed and high density residential land use to expand housing densities and create opportunities for life-cycle and affordable housing. • The Plan designates areas for mixed use development to accommodate retail, commercial, and housing uses to improve access to jobs and other services. • The Plan protects natural resource areas by identifying sensitive areas and planning development accordingly. The Plan identifies strategies and policies to protect natural resource areas. • The plan protects the quality and quantity of water resources. • The Plan designates higher density housing opportunities along major transportation corridors to increase efficiency of the region’s transportation system and take advantage of future transit opportunities. • The plan creates opportunities for a variety of transportation methods, including automobile, walking and bicycling. • The plan provides opportunities for economic development by providing areas for commercial, office and industrial uses throughout the City. • The Plan achieves a minimum net density of 3 units/acre to ensure the region’s infrastructure is used efficiently. ForEcasts Corcoran is a unique community with a large amount of desirable undeveloped land. Due to its undeveloped nature, recent availability of municipal services, and the current economic state at the time of 2040 Plan preparation, it is a challenge for both the Metropolitan Council and the City to accurately anticipate the City’s rate of growth. The 2040 forecasts are shown in Figure 1-5. The potential number of housing units that could be accommodated in the 2040 urban service area exceeds the population and housing forecasts. The excess capacity of the 2040 service area will provide greater development flexibility as growth occurs. However, the City will manage development and the pace of growth based on the forecasts. It must be recognized that these figures present the urban service area only and do not provide projections for housing units and population over the entire City. The Metropolitan Urban Service Area (MUSA) sewer system has been extended into the City, which has allowed new residential development in the southeast portion of the City and provided services to the existing industrial park in 2017. The availability of sanitary sewer increases opportunities for variety of residential densities and mixed residential uses, increasing housing options, and life-cycle housing in the community. It expands the City’s ability to compete for commercial, industrial, and employment opportunities. The 2040 Land Use Plan will guide and manage development pressure and growth by determining future land uses, development intensity, and areas for environmental protection. This Chapter establishes growth management strategies for the City to ensure that adequate infrastructure is in place to accommodate new growth and maintain a balance between residential and non-residential development.

The Metropolitan Council uses a slightly different calculation to determine compliance with the regional policy than the City used to evaluate the overall land supply. Because the 2030 Comprehensive Plan and development planned prior to 2030 was already determined to comply, the calculation for determining compliance of the 2040 Comprehensive Plan changes as follows: • Land planned for development prior to 2030 in the 2030 Plan that continues to be planned for development by 2030 in the new 2040 Plan is excluded from the calculation. • Land planned for development prior to 2030 in the 2030 Plan that has now shifted in the Staging Plan to develop after 2030 is included in the calculation. • The land outside the 2030 MUSA that was added to the 2040 MUSA is included in the calculation. • The City may take credit for units in excess of the minimum density requirements for those developments included in the plat monitoring program (through 2016). The City may add the number of units and it gives the City some credit for approving plats that exceed the minimum densities allowed by the Comprehensive Plan. The results of the density calculation using the Metropolitan Council’s policy guidance is shown in Table 2-4. The Land Use Plan meets the minimum density of 3 units per acre for areas not approved in the 2030 Comprehensive Plan.

The High Density Residential and Mixed Use areas are concentrated along major transportation routes to maximize the efficiency of these routes and relieve stress on the local road system. A variety of commercial, industrial and public/semi-public land uses are provided to provide employment, retail, service and recreational opportunities to residents and landowners in Corcoran. Each of the land use categories is described below.

The Metropolitan Council categorizes this area, existing outside the 2040 MUSA boundaries, as Diversified Rural. Diversified Rural areas are not within the Metropolitan Council’s Long-Term Sewer Service area. However, the Metropolitan Council is in the preliminary stages of planning a new sanitary sewer treatment facility to serve the northwest metropolitan area, including those parts of Corcoran designated as Diversified Rural. The City will continue to monitor this planning effort. The Rural/Ag Residential areas will continue to be defined by natural areas, such as wetlands and floodplains, and areas that are utilized for planted fields, pasture land, hobby farms, and large residential lots. The community must balance the desire all residents have for this rural experience with the needs of individual property owners in this area who may need to realize the value of their property now, rather than waiting for the arrival of urban services. This effort can be accomplished in part by amending the Open Space and Preservation Plat ordinance, which allows the use of smaller lots where natural resources are preserved and the development is designed to allow for future maximization of undeveloped spaces. This will allow a landowner to develop a portion of land while holding the remainder in a tract that is viable for future development. The undeveloped portion will not be held as open space for permanent conservation; rather, it will be held for future sewered densities through a temporary development agreement or deed restriction. The ordinance will also provide incentives for protecting natural resources. agricultural PrEsErvE This land use designation is specifically used to implement the requirements of the Metropolitan Agricultural Preserves program. All land parcels in the Rural/Ag Residential land use designation that meet the requirements for eligibility in the Metropolitan Agricultural Preserves program according to MN Statute §473H may apply to the City for enrollment. When land is removed from the Metropolitan Agricultural Preserve program, the land use will revert to its underlying land use: Rural/Ag Residential outside of the MUSA and Low Density Residential in the MUSA. Existing rEsidEntial This land use designation accounts for existing residential development in the City of Corcoran at very low densities. The density for this area is 0.50, or roughly 1 unit per 2 acres. loW dEnsity rEsidEntial This land use category identifies areas for single-family detached residential development at an average density of 3 to 5 units per acre. This land use category will be Corcoran’s predominant land use inside the 2040 MUSA boundary. Residential development within or adjacent to environmentally sensitive areas will be guided as Low Density Residential to reduce development impacts to these areas. This category also includes Shamrock Golf Course and Pheasant Acres Golf Course. This category also includes Shamrock Golf Course and Pheasant Acres Golf Course. Low Density Residential areas will also be located contiguous to Ag/Rural Residential areas to help create a transition from the rural environment to a more urbanized land use pattern. MEdiuM dEnsity rEsidEntial and MixEd rEsidEntial The intent of the Medium Density Residential district is to accommodate mid- density clusters of small lots and attached townhomes, ranging from 5 to 8 units per acre. Similarly, the Mixed Residential District will accommodate a range of housing types including a mix of small lot detached homes and attached side-by-side (row) or stack townhomes at a density of 8 to 10 units per acre. These medium-density housing categories are planned in areas that provide transitions to more intensive land uses, are served by higher-functioning roadways and are adjacent to other higher-density or mixed-use areas where a greater concentration of services will be provided. high dEnsity rEsidEntial The purpose of this land use district is to accommodate the development of multiplex and low- to high-rise apartment buildings and condominiums. Development will occur at a density of 10+ units per acre. Architecture, landscaping, open space, resident recreational areas, and surface water retention features are important in high density residential areas to ensure that development is appropriate and consistent with the community’s character and environmental best practices. Ideally, streets and buildings will be designed around pedestrians to accommodate alternative transportation use such as bicycles and transit. MixEd usE The intent of the Mixed Use district is to allow for developments that combine residential and commercial uses into a coordinated, planned development project. Typically, mixed use developments will include townhomes, low- and high-rise apartments, retail buildings, and offices. Development may be stacked, with office or housing units located above main floor retail space. Residential density is planned at 10 or more units per acre. Not all mixed- use developments will be required to incorporate residential units. Mixed use developments will be oriented around pedestrians rather than automobiles. By providing walkable mixed-use areas, stress on the transportation system is reduced and a “sense of place” is created. A portion of the Mixed Use designation is located on the east side of County Road 116 in what is considered the Downtown Core.This area is envisioned to provide a “main street” experience, with retail shops and service businesses mixed with residential and offices on the second floors of buildings. The Town Center is the walkable traditional neighborhood supporting the Downtown Core. The Town Center is bound by City Hall on the north, County Road 10 on the south, County Road 116 on the west and Maple Hill Road on the east. The Town Center is intended to support the Downtown Core through walkable blocks, a variety of housing types and densities, and a unified public realm aesthetic. The Downtown Core is a subset of the Town Center and shall have additional design guidelines. Special emphasis will be placed on providing accessible destinations and inviting design. Housing, retail, and other destinations are located in or near the Downtown Core to invite walking by creating pleasant and safe routes within the Town Center. A Town Square, City Hall Park, and 1 small Neighborhood Park create additional opportunities for physical activity and social connectedness. Uses within the Town Center include: mixed use, public/semi-public, and mixed residential. The Town Center shall be developed in compliance with the standards in the Zoning Ordinance and the standards in the Corcoran Southeast District Plan and Design Guidelines adopted in 2016. This plan will be modified to reflect the transportation policy changes in this 2040 Plan, but the general principles remain unchanged. The area located between the intersections of County Road 116 and County Road 30 on the west and County Road 30 and County Road 101 on the east is also guided as Mixed Use. Future connecting improvements to County Road 30 will enhance its role as a major east-west corridor to Highway 610 in Maple Grove. This General Mixed Use District will likely include a mix of uses, including commercial and retail services and offices. The Zoning Ordinance establishes the Downtown Mixed Use and General Mixed Use district to support this land use designation. The Zoning Ordinance provides 2 distinct districts to acknowledge the uniqueness of each area. Within the district zoning standards, site and design performance standards have established to support the vision and concept plans developed for each of the mixed use areas. Additionally, design guidelines have been adopted as part of the Zoning Ordinance for each of these areas. The City expects approximately 1/2 of these areas to develop with residential uses at a variety of densities but the City will plan for 8-30 units per acre on average. coMMErcial The areas are intended for development only when sanitary sewer and water are available. In addition to this land use category, additional commercial opportunities will be available within Rural Service/Commercial Mixed Use and Business Park districts. Development of Commercial areas should include architectural themes and high-quality designs that reflect the rural character of the City as defined by the adopted Design Guidelines. Building designs and materials promoting this aesthetic, and details such as planting beds, ornamental fencing, decorative lighting, and sidewalks, will be required in Commercial areas. rural sErvicE/coMMErcial Located at the intersection of County Road 10 and County Road 19, the Rural Service/Commercial category provides a separate and distinct area for commercial land use. This area is intended to continue as a rural service area with commercial uses that may be maintained utilizing individual septic systems or approved alternative systems. This area is not expected to have public sanitary sewer and water service within the 2040 planning period. This area will have less strict building and site development standards than other commercial areas to allow for contractors’ yards and similar uses. The area can provide a relocation opportunity within the City for businesses that would not typically locate in high land-value areas. Zoning regulations will be developed to address the minimum design standards and specific screening requirements for this unique land use. BusinEss Park The Business Park category is intended to accommodate large office buildings and corporate campus developments, medical offices, technology centers, or light-industrial and office-warehouse developments that require larger sites. The Business Park district is located on County Road 30 east of County Road 116 and reflects the anticipated, substantial increases in traffic through the County Road 30 corridor to the planned, final stretch of Highway 610. These traffic levels will increase visibility for a business park and support the vision for this corridor as a major employment center. Figure 1 - Town Center Plan Adopted 2016 Figure 1 - Downtown Plan adopted 2016 Draft Copy -- 2/1/2018 47 light industrial The Light Industrial category is intended to provide areas for manufacturing, warehousing, automotive, trucking, office, and other related industrial uses. These uses typically are not viewed as compatible with residential or some commercial uses. Parks/oPEn sPacE and PuBlic/sEMi-PuBlic land usE catEgoriEs These categories include Rush Creek golf course, all places of worship, the City Hall, Public Works, all public parks and land owned by the Rockford School District. staging The Metropolitan Council asks developing cities to provide anticipated rates of growth in 5-year increments. In its Thrive MSP 2040 vision plan, the Metropolitan Council defines strategies for developing communities to implement the policies. These strategies include the following: • Stage local infrastructure and development plans to accommodate 20 years’ worth of forecasted growth. • Select and implement local controls and tools for timing and staging of development throughout the community. • Adopt ordinances or policies to accommodate growth and use land and infrastructure efficiently. • Identify areas reserved for future urban development and develop strategies to minimize development in those areas that could preclude future urban development. • Plan for necessary infrastructure improvements. Development of a staging plan also provides several benefits to the City. A staging plan: • Creates an orderly, logical growth pattern based on development patterns and availability of infrastructure. • Allows for a connected transportation network. • Clearly defines when land is available for development. • Allows the City greater control over the pace and location of new development and the provision of necessary services. • Provides greater ability to plan, budget, and set goals for future development. The Staging Plan reflects anticipated sewer service areas located in the 3 corners of the City, where regional interceptors will be extended from adjacent communities. The Staging Plan boundaries follow the 2040 Land Use Plan boundaries. Areas outside the Staging Plan boundaries are the Rural/Ag Residential land use category, where development polices will be created to provide flexibility for development while preserving large land areas for future urbanization. The 2040 Staging Plan is displayed in Map 2-3. Future land uses are broken down by staging areas and presented below in Map 2-3. Density assumptions were included to estimate the potential number of housing units to be accommodated in each staging area.

The allowed pace of development will be based on the population and housing forecasts presented in Chapter 1, with an average of 230 units/year over the 20-year life of the plan. groWth ManagEMEnt groWth FraMEWork The City Council authorized an extensive public participation process for the adoption of the 2030 Comprehensive Plan. In the 2030 Comprehensive Plan, a large area of the City was added to the Metropolitan Urban Service Area (MUSA) to accommodate anticipated exponential growth. Since that time, growth has been less than anticipated and Metropolitan Council forecasts have been adjusted to reflect market conditions. The MUSA intentionally includes more land than is needed to accommodate the forecasted growth. This policy was adopted as part of the 2030 plan to allow landowners and the City the flexibility to allow development to respond to market demand within the framework of this plan. The City of Corcoran seeks to promote a more efficient use of land to allow the City to balance the demand for urban services and the ability of the City to provide those services in a fiscally and environmentally responsible manner. The City will create a Growth Management Policy that will manage development based on the timing and sequence illustrated in the 2040 Sanitary Sewer Service Staging Plan. The Growth Management Policy will serve as a tool to determine when an area will open for development. A multitude of factors may cause certain areas of the City to develop at a faster rate than others. This Policy is intended to implement the Sanitary Sewer Service Staging Plan while at the same time provide flexibility to address unpredictable market conditions. Another goal of the Growth Management Policy is to ensure that the City possesses sufficient administrative capacity to conduct the permitting and construction supervision processes. City staff is responsible for assessing adherence to the Comprehensive Plan, enforcing standards and requirements contained in codes and ordinances, determining that all the necessary public infrastructure and services either are in place or will be built, and ensuring that proposed development will not place a disproportionate economic burden on the community. It is essential that City staff has adequate capability to ensure that these requirements are met, consistent with City, regional and State laws, policies and regulations. The Growth Management Plan may include the following guidelines: • A certain percentage of the net developable area in a current staging area must be platted, and a certain percentage of these platted lots must have received Certificates of Occupancy before development will be allowed in subsequent or other staging areas. Staging in different districts will be considered independent of one another. • A development ratio of non-residential to residential acreage may be required to manage tax base and infrastructure debt the City may incur with new development. • Feasibility studies will be required to identify utility and transportation improvements necessary to support new development. • Developer commitments to pay costs associated with development will be obtained. • The City will evaluate land availability in each staging phase on an annual basis, or more frequently if warranted, to determine remaining development capacity within each staging area. The Growth Management Policy may allow acceleration in staging if: • A large-scale master planned project is located within both the current and next staging area and adequate infrastructure is in place or will be available to accommodate growth within the next staging area. • A unique development project is proposed that achieves significant public benefits such as substantial preservation or restoration of natural resource areas, open space, park and/or trail dedication in excess of requirements; unique and desirable life-cycle or affordable housing opportunities; or greater tax base diversification. Any development in an area prior to the designated staging phase will require a Comprehensive Plan Amendment. Figure 1 - Town Center Plan Adopted 2016 Figure 1 - Downtown Plan adopted 2016 PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 48 ProteCting sPeCial resourCes State law requires that comprehensive plans include strategies for protection of special resources including historic preservation and aggregate (mined) resources. These strategies are discussed below. historic PrEsErvation The Metropolitan Land Planning Act (Minn. Stat. 473.859 Subd. 2) requires that local comprehensive plans include a historic preservation element. Historic assets help to promote community pride and create a sense of community. The City of Corcoran values its historic assets and has developed this comprehensive plan to preserve the longstanding pattern of land use that makes Corcoran a unique place to live and work. To support this goal, the City will work toward the creation of an inventory of historically significant buildings, sites, landscape features and other landmarks.

Corcoran has the opportunity to provide opportunities for housing options that will meet the needs of current and future residents. Housing should meet the needs of individuals and families throughout their lives, including single-family detached homes, townhomes, condominiums, apartments and senior housing. The 2030 Comprehensive Plan identified a need to plan for and manage the development of a variety of housing types to ensure that development occurs in an efficient and cost-effective manner and represents an enhancement to, and not a negative impact on, existing residential neighborhoods. The 2040 Land Use Plan continues to provide housing opportunities for Corcoran’s entire population (singles, families, and senior residents) through a variety of residential land uses and densities, including medium density, mixed residential, high density and mixed-use areas. The purpose of the Housing Plan is to establish plans and programs to meet the existing and projected housing needs in Corcoran. The Plan will guide the community’s integration of housing goals and policies into land use, infrastructure, community development, transportation, and natural resource decisions. This Housing Plan satisfies the requirements of the Metropolitan Land Planning Act and stipulations of MN Statute §473.859, Subd 2(c) and Subd 4. The plan includes background information on current housing supply and an assessment of current and future housing needs. Chapter 11 of the Comprehensive Plan includes implementation strategies for the Housing Plan and other plan chapters. housing goals and PoliCies The vision statement, as described in Chapter 1, defines what the City of Corcoran should look like in the future. The goals and policies guide the Housing Plan to help achieve that vision for housing development. The goals and policies that follow were developed from the goals and policies prepared in the 2030 Comprehensive Plan and reaffirmed for the 2040 Comprehensive Plan Update. These goals and policies are listed below and are considered the City’s Housing Action Plan. Goal 1: Provide a healthy variety of housing types, styles, densities and choices to meet the housing needs of residents. Policy 1: Provide a mix of housing types to provide housing opportunities, including continued single-family growth and new opportunities for multiple family and senior housing developments. Policy 2: Periodically review land use regulations to determine the effectiveness of current ordinances in encouraging additional affordable units as well as encouraging modifications to keep existing housing stock desirable and livable. Policy 3: Allow the creative use of site planning or Planned Unit Developments (PUD) to provide flexibility for development containing affordable housing, such as a reduction in lot size, setbacks, street width, floor area and parking requirements. Policy 4: Encourage innovative subdivision design, including clustering techniques to preserve open space or natural features. Policy 5: Promote development of neighborhood “life-style centers” that incorporate housing in a range of densities and affordability limits in close proximity to shopping, services, daycare, and medical services. Life-style design should include safe access to parks and schools and the ability to walk, bike, or have access to transit. Policy 6: Consider developing a list of available resources and providers of in-home services to older adults and those with special needs. Goal 2: Promote housing rehabilitation. Policy 1: Support first-time homebuyers’ programs to assist new homeowners entering the market for existing homes. Policy 2: Consider supporting and actively promoting housing rehabilitation programs for existing owner-occupied homes and rental buildings or units. This includes promotion of all County and State programs and non-profit programs. Policy 3: Consider utilizing the City’s website, newsletter and other sources for promotion and advertising of housing programs. Policy 4: Consider creation of a Housing Maintenance Code to maintain existing housing stock. Policy 5: Consider programs that encourage maintenance of existing houses, including a housing remodeling fair, neighborhood watch programs, City beautification programs and City-wide clean-up programs. Goal 3: Improve the availability of affordable housing and senior housing. Policy 1: Developers should be encouraged to address the provision of affordable housing within all new residential developments within the 2040 Metropolitan Urban Service Area (MUSA). Policy 2: Consider participation in the Livable Communities Act Local Housing Incentives Program. Policy 3: Utilize techniques such as land trusts to maintain long-term affordability. Policy 4: Partner with, support and market programs offered by the County, State, Minnesota Housing Finance Agency, Federal government, and non- profits to fund the development of affordable housing. housing assessment housEhold ForEcasts Corcoran will continue to plan infrastructure and housing investments to meet the projected growth over the next 20 years. The City’s housing supply should be diverse and consist of a variety of styles and price ranges to allow residents the option of living in Corcoran their entire lives, and to provide the opportunity for their children to do the same. housing dEvEloPMEnt trEnds Table 3-1 and Figure 3-1 show Corcoran population and household growth since 1970 and forecasts through 2040.

Details on the age of Corcoran’s housing stock are presented in Figure 3-4. A majority of homes (51 percent) in Corcoran were constructed in the 1970s and 1980s. Only 10 percent of the housing stock was constructed prior to 1939. As a result, Corcoran sees fewer housing maintenance issues than many older communities. housing PricEs and rEnts According to the 2010 Census, 96 percent of housing units in Corcoran were owner-occupied and 4 percent were renter-occupied.

Renter occupied units account for a small portion of the current housing in Corcoran. Figure 3-7 displays the median gross rent for these units. housing needs aFFordaBlE housing As part of the 2040 Regional Development Framework, the Metropolitan Council estimated that approximately 37,900 additional affordable housing units will be needed in the region during the planning period of 2021-2030. As part of Thrive 2040, the housing policy plan defines affordable housing as housing affordable to those householders earning 80 percent of area median income. According to Metropolitan Council 2017 Affordability Limits, the area median income for the 7-county Minneapolis-St. Paul (MSP) area adjusted by HUD to be applicable to a family of 4 was $90,400 in 2017. A family of 4 at 80 percent of this figure earns $72,320 and would be able to afford a home at a purchase price of $236,000 in 2018.

Using the total of 1,933 housing units from 2010 Census data, these 732 homesteads account for approximately 38 percent of the City’s housing stock. Most of the affordable housing at less than 50 percent AMI comes from the Maple Hill Estate manufactured home park in Corcoran. There is uncertainty associated with the extent to which future buyers will view a home as an investment and the amount of any premium they will be willing to pay for the benefits of ownership versus rental. While recent drops in interest rates and lower home prices have increased the availability of affordable housing options, changes in mortgage lending practices create new obstacles for lower income households to obtain financing. It is clear that jobs and income levels are the driving force in demand and sustainability. The Metropolitan Council has allocated a certain number of affordable housing units to be provided between 2021 and 2030 for each community within the region, based on the following 4 criteria: • Household growth potential • Ratio of local low-wage jobs to low-wage workers • Current provision of affordable housing • Transit service Based on their analysis, the Metropolitan Council’s affordable housing goal for Corcoran is to create 194 new affordable housing units between 2021 and 2030. The affordable housing allocation accounts for approximately 18 percent of the forecasted housing added from 2021 to 2030. The affordability limit is 80 percent of area median income for both owner-and renter-occupied housing units. To provide opportunities for affordable housing in the community, the City is taking the appropriate regulatory measures within the Comprehensive Plan by guiding areas for higher density housing and including policies to promote affordable housing in residential land use areas. Guiding land at greater densities increases opportunities for affordable housing, as per-unit land and development costs decrease when density rises. While the City is doing its part in creating a Land Use Plan to guide areas for higher density housing, barriers to development of affordable housing still exist in Corcoran and the region. Some of these barriers are beyond the City’s control and include the following: • Steady increases in land prices and construction costs • Physical limitations of land due to wetlands, poor access, and poor soils that would increase the cost of development or construction • State, County and local tax structures • Lack of transportation and employment infrastructure Corcoran will promote affordable housing most effectively by adopting and enforcing land use and zoning standards that do not impede or deter affordable housing. Metropolitan Council defines a cost burdened household as one that is spending 30 percent or more of their annual household income on housing. The data on the percentage of owner and renter households in Corcoran that are classified as cost burdened is displayed in Figure 3-8. A factor that contributes to the significant drop in cost burdened renters is the drop in average rent for Corcoran from 2010 to 2015 shown in Figure 3-8. This drop lowers the percentage of income spent on housing enough that most renters are no longer considered cost burdened. Draft Copy -- 2/1/2018 60 liFE-cyclE housing Life-cycle housing is defined as housing that meets the housing needs of individuals and families throughout their lives. Generally, people desire diverse types of housing at various stages of their life-cycle. Usually, people between the ages of 0 and 19 are students living with their parents. Those between the ages of 20 and 24 are often renters and do not often become first time home-buyers until they reach the ages of 25 to 34. First-time homebuyers (25-34) and move-up renters often prefer to purchase modestly- priced single-family homes, townhomes, or rent upscale apartments. People aged 35 to 49 often are in their peak earning years and can afford to buy a larger home with more amenities, referred to as move-up housing. Empty nesters are usually between the age of 50 and 64 and many of them may decide to downsize to a smaller housing unit, as with younger seniors (between the ages of 65 to 74). This choice may include renting a multi- family unit, purchasing a lower-maintenance multi-family housing product such as a condominium or townhome, or purchasing a home in a retirement community. Older seniors (74 and above) may begin to require some level of assisted housing. sEnior housing As the community ages, there will be an increase in demand for smaller, low maintenance housing designed for the senior population. This demand might be accommodated through a variety of townhouse styles or apartments in mixed use settings. Empty nesters are a particularly active group on the younger end of the senior age range and locating developments near some of Corcoran’s natural amenities and retail/service areas will be enticing to this group. For seniors, no longer able to live alone, supportive housing options such as assisted living or memory care units will be needed.

Economic health is an important component of a healthy and thriving community. A strong commercial and industrial base provides jobs to community residents, contributes to a community’s tax base, and can be a source of psychological strength to a community. Commercial and industrial development will provide additional revenue for the City, which currently relies largely on residential property taxes for revenue. Commercial and industrial tax base will fund increased City services prompted by City growth. The 2040 Plan recognizes the inherent link between commercial development and the availability of skilled and educated workers, affordable housing, developable land and infrastructure. eConomiC develoPment goals and PoliCies The City of Corcoran recognizes the importance of each component of the economic development cycle in the overall health and economic stability of the community. The City addresses economic development issues through the following goals and policies: Goal 1: Promote cooperative efforts and utilize existing resources for economic growth in the City. Policy 1: Continue to identify and tap into local, State and Federal resources to enhance economic development. Policy 2: Explore County-wide economic development coordination options. Policy 3: Promote coordination of the educational system and the business community to ensure the availability of qualified workers. Goal 2: Promote economic stability and diversity to provide job opportunities to residents. Policy 1: Support efforts to retain existing businesses and facilitate their expansion. Policy 2: Support efforts to recruit new businesses and industries in appropriate locations. Policy 3: Recognize the need to expand infrastructure in the City, including but not limited to roadways, parks/trails, utilities and telecommunications infrastructure, to support and promote continued economic development. Policy 4: Target financial resources and programs to attract businesses that have an emphasis on job creation and businesses that meet or exceed livable wage requirements. Policy 5: Encourage the availability of a range of housing types and values to accommodate an ample work force. Goal 3: Promote efficient, planned commercial and industrial development. Policy 1: Identify key commercial and industrial development opportunities in planned growth areas at locations with access to major transportation systems. Policy 2: Encourage and facilitate infill development on vacant parcels to ensure maximum efficiency of land use. Policy 3: Encourage compact commercial developments that will make efficient use of infrastructure and resources. Policy 4: Encourage industrial, office, business and commercial development to locate within master planned industrial parks, business parks, or in the Town Center area. Goal 4: Enhance the character of the City’s commercial and industrial development. Policy 1: Support the provision of open/green space within commercial and industrial development. Policy 2: Promote the rehabilitation and redevelopment of under utilized facilities by pursuing and making available various financial programs and assistance. eConomiC assessment Expansion of the local economy is often tied to existing employers and industries. This section analyzes the existing types of industry concentrated in the City of Corcoran and the competitive environment defined by the presence of industry in surrounding communities. Corcoran’s existing employment base is dominated by small construction- related firms. This is in contrast to the metro area, which is much more diversified in its employment base. For example, approximately 41 percent of all jobs in Corcoran are construction-related, whereas approximately 5 percent of all metro area jobs are construction-related. (DEED Occupational Employment Statistics (OES) Therefore, as Corcoran looks to expand its commercial and industrial tax base, it will need to consider ways to diversify its existing employment base. Figure below to be updated. Although Corcoran’s employment base more than doubled between 1990 and 2010, it still remains well below neighboring communities, especially Rogers, Maple Grove, and Plymouth (Table 15). Because some of these communities will continue to develop in coming years, Corcoran’s employment base has been drawn back from the 4,000 job increase forcasted in the 2030 Comp Plan to approximatley 1,200 job increase in the 2040 forcasts. ECONOMIC COMPETITIVENESS PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 66 Development in neighboring communities will continue to impact Corcoran for many years. There are several significant concentrations of commercial and industrial districts within 5 miles of Corcoran’s boundaries in neighboring cities including Rogers, Dayton, Maple Grove, Plymouth, and Medina. Most of these districts are situated at the intersection of 2 or more major highways. Each of these districts will strongly compete with any new commercial or industrial development within Corcoran for many years to come. Although commercial and industrial development has been limited in Corcoran, the City has begun to more actively pursue economic development opportunities in recent years. The City has supported development and extended municipal services to its downtown area located at County Road 10 and County Road 116. Several commercial and industrial users are already located in this district, and the City has already identified its downtown as a key growth area. An industrial district located in the southwest portion of the City along Highway 55 and County Road 19 also has been promoted for development in the coming years. eConomiC develoPment oPPortunities The City anticipates the demand for commercial and industrial development will increase significantly by 2040. Therefore, the City’s Land Use Plan identifies large areas of commercial, industrial, business-park, and mixed land use that will provide for a mix of jobs, ranging from retail and commercial service jobs to high end technology jobs. The City’s development plan for its downtown area provides an opportunity for additional economic development. The City has guided this area for Mixed Use on the 2040 Land Use Plan, providing flexibility for future development. The development plan is intended to promote investment in Corcoran’s downtown, solidifying the area as an important community asset and focal point. A future I-94 Brockton interchange planned in Dayton, and a Highway 610 interchange planned in Maple Grove, will impact the northeastern portions of Corcoran. These roadway improvements will significantly improve access to the City, making it a more desirable location for commercial and industrial development. To serve this future demand, the City has planned a large industrial/business park area and Commercial/Mixed Use development in the northeastern portion of the City near each interchange. Additionally, expanding municipal sewer and water services will provide for increased housing opportunities in the City. The continued increase in housing units will create additional demand for commercial services. Corcoran’s parks, trails and open space system will be an integral part of the community’s life. The system will provide recreational opportunities for park system patrons, while preserving existing natural and historic resources. The parks and trails system should be authentic to the identity of the City and unify neighborhoods to reinforce a sense of community pride.

The system will provide recreational opportunities for park system patrons, while preserving existing natural and historic resources. The parks and trails system should be authentic to the identity of the City and unify neighborhoods to reinforce a sense of community pride. This plan to develop, maintain and grow the park and trail system provides a benchmark from which to make decisions as investment opportunities arise. Goals provide decision-making guidance to the City. Policies provide actionable steps the Parks and Trails Commission and policymakers can take to ensure stewardship of financial, natural, and recreational resources and create a parks and trail system that is representative of the community’s values. Diligent planning will result in: • A system where making healthy lifestyle choices is integral to daily life, • A system with quality resources and facilities that attract new development, businesses and visitors, • A venue for strengthening community engagement by giving visitors places to gather and interact, • A community where key natural resources are protected before development occurs, • A City that is known for promoting a high quality of life. aPPliCation This Plan places emphasis on park and trail development within the Metropolitan Urban Services Area (MUSA) as new development occurs. While park and trail locations are also identified in areas outside the MUSA, plans and proposed corridors are for guidance purposes and will be implemented over the long term as development occurs and opportunities to work with landowners arise. The Parks and Trails Plan uses the City’s 2003 Natural Resource Inventory as a foundation for the park and trail system to be developed in Corcoran over the next 20 years. The plan incorporates national trends and standards as available from the National Recreation and Park Association (NRPA). NRPA publishes standards to help communities in planning, acquisition and development of park and open space. In more recent years, the NRPA is encouraging communities to benchmark their metrics and enter the data into their national database. Due to the limited number of communities participating in their benchmarking program at the time of this report, it is unclear how Corcoran’s parks services compare to other communities of comparable size in Minnesota. The standards that the NRPA has used in the past provides guidance for how to place parks by park type and the general facilities you might see in each park. The area within the 2040 MUSA is the emphasis for new park and trail development. goals and PoliCies Goal 1: To implement this Parks and Trails Plan based on the needs of Corcoran residents and park system patrons. Policy 1: Apply this plan when making recommendations to City Council. Review pertinent information, analyze alternatives and make recommendations to the City Council on park and trail issues. Policy 2: Inform and seek input from other City advisory commissions on any issues or improvements that may be applicable to that commission. Policy 3: Respond to the increasing maintenance, planning and recreational demands made by the City and its park system patrons. Policy 4: Track changes to the park and trail system to ensure a well- considered network. Goal 2: To work cooperatively with neighboring communities, Hennepin County, the State of Minnesota and others in planning, developing, and financing the local park system. Policy 1:Seek compatibility with adjacent local community plans and metropolitan, State and Federal plans and programs. Policy 2: Seek cooperation, coordination and participation with local school districts in planning the joint use, development and operation of the park and trail system. Policy 3: Encourage community volunteer organizations to participate in park and trail development. Policy 4: Require park dedication from all developers (commercial, industrial and residential) in the form of cash or land, according to the Park Dedication Ordinance and the fee schedule set by the City Council. All cash will be directed to the Park Fund and will be used for park land acquisition and development projects. Policy 5: Review the park dedication formula on an annual basis to ensure it supports the needs of the park system and is comparable with area metropolitan communities. Policy 6: Acquire park land when possible, and in accordance with the City’s Parks and Trails Plan, to minimize costs and potential conflicts. Goal 3: To develop a park system the public values and visits. Policy 1: Design and build parks and trails early in the development process, so that they are available to new park system patrons. Policy 2: Include private parks, when planned and funded by developers, as a neighborhood feature based on the provisions of the City’s Park Dedication Ordinance. PARKS AND TRAILS PICTURE PLACEHOLDER Figure 5-1: 2040 MUSA The area within the 2040 MUSA is the emphasis for new park and trail development. Draft Copy -- 2/1/2018 72 Policy 3: Maintain an equitable distribution of parks throughout the community. Policy 4: Develop a parks and trails system that is safe, enjoyable, and accessible. Policy 5: Provide multi-use and multi-seasonal programs and activities. Policy 6: Provide park system patrons with timely information regarding park and trail facilities and programs. Policy 7: Establish design standards that create unity within the park and trail system and that emphasize the character of the City, its history and landscape. Policy 8: Park design should incorporate a general theme, but also allow diversity among parks to adapt to natural features, local history, or neighborhood character and needs. Goal 4: To develop a system of parks and trails, with a variety of active and passive uses, that reflect the special character of the City, its history, and natural resources. Policy 1: Select land for parks, trails or open space based on: a. Its designation as a park or trail search area in the Parks and Trails Plan, b. Its scenic or unique natural features, c. Its ability to support desirable wildlife populations, d. Its performance of important environmental functions, e. Its proximity to the Natural Resource Corridors identified in the Natural Resource Inventory, f. Its qualities conducive to recreational development, g. A demonstrated need for additional parkland exists in an area. Policy 2: Ensure park names reflect location by incorporating local histori- cal names or features, a local access road, neighborhood name, benefac- tors or prominent natural features of the area. Policy 3: Develop a consistent signage policy for parks system, including directional and informational signs. Policy 4: Preserve outstanding natural areas by discouraging development of prominent or highest quality landscape features and conserving natural resource areas. Protect wetlands and woodlands from undesirable impacts and fragmentation. Restore them to a high-quality condition when possible. Goal 5: To provide a safe, equitable, and convenient trail network. Policy 1: Apply this plan to coordinate development of the trail system. Policy 2: Connect future trails to existing and adjacent community trails. Policy 3: Encourage the use of utility easements and transportation rights- of-way for on-road route development. Policy 4: Respect individual property rights. Trail development and routing should be a cooperative effort between the City and the landowners along the proposed route. Existing neighborhoods are encouraged to request trails and work with the City to identify their routes. Policy 5: Require a 20-foot minimum easement to provide adequate bicycle and pedestrian circulation or access to schools, parks, downtown, churches, or other facilities. Policy 6: Implement safe pedestrian crossing facilities on main roadways. Policy 7: Maximize user safety by thoroughly considering conflicts between trail user groups, for example, snowmobiles and equestrians. Policy 8: Continue to show snowmobile trails on the City Parks and Trails Plan. Snowmobiles are an important recreational activity for many residents. A private organization maintains the current trail system. While the City does not own or maintain these trails, the City will make applicants aware of the desire to maintain routes through the City as development occurs. areas outside the 2040 metroPolitan urBan serviCe area (musa) Boundaries guidElinEs The following guidelines will be applied to development proposals outside the 2040 MUSA boundary: • Park and trail policies in areas outside the 2040 MUSA boundary will be consistent with the City’s Comprehensive Plan and Subdivision Ordinances. • Relevant development proposals will be presented to the Parks and Trails Commission before City Council approval, thereby allowing for review and recommendations regarding incorporation of trail easements, open space acquisition or park facilities. • Park facilities generally should not be planned outside the 2040 MUSA, except for: • Trails that have been identified on the Natural Resource Inventory or the Parks and Trails Plan maps, • Parks that have been identified on the Parks and Trail System map, • Protection of significant natural areas that have been identified on the Natural Resource Inventory, • Athletic facilities may be considered, but are preferred in areas closest to the 2040 MUSA. • Proposed parks and trails shown on the Parks and Trails System Map outside the 2040 MUSA areas are for guidance purposes and will be implemented over the long term as a part of new development through development dedication or cooperative purchase. Park ClassifiCation Parks are divided into 1 of 3 categories: Neighborhood Park, Community Park and Linear Park. Parks may serve more than 1 purpose, for example a community park may also serve the immediate neighborhood park needs in addition to a more regional community park demand. The following park types and standards will be developed in Corcoran. nEighBorhood Park Neighborhood Parks are the most local unit of the park system, providing area for recreational activities such as field games, court games, playground, skating, and neighborhood centers. These parks prioritize user groups living in the neighborhood. They are identified as NP – Neighborhood Park on the system map. Neighborhood park sites should be in proximity to residential neighborhoods. Their design may be as simple as a playground or as intense as a public square. Siting neighborhood parks adjacent to community parks and local linear parks, corridors and parkways will expand the function of all types of open space. It will also entice residents from throughout the community to visit the park ensuring new parks do not function as private facilities for new developments. Neighborhood park development criteria generally include: • An overall size of 5-20 aces, • A Service Area of 1/4 to 1/2 mile, • A physical geography suited for intense development, • A frequency of 1 neighborhood park per 5,000 residents. Figure 5-2: 2040 MUSA The guidelines above apply to the area outside the 2040 MUSA. Draft Copy -- 2/1/2018 73 coMMunity Park Community parks serve a wider user group than neighborhood parks, and are often in proximity to secondary schools and other public facilities. These parks seek to preserve unique landscapes and natural areas, and as they have a larger overall size, the programming of passive and active recreation may occur within the same park without conflict. Community park development criteria generally include: • An overall size of 20-100 acres, • A service area of up to a 2-mile radius, • A frequency of 1 community park per 15,000 residents. In addition to the existing Corcoran Community Park at County Road 10 and 50, there are 2 other types of planned parks that will serve the wider community and fall into this category: Community Playfields and Open Space/Natural Parks. Community Playfield Community playfields, identified as ASA-Athletic Search Area on the system map, are areas for intense recreational facilities such as athletic fields and swimming pools. Playfields should be integrated into community parks or may be co-located with school athletic facilities. They may also include a neighborhood park use. oPen sPaCe/natural Parks These parks are characterized by high-quality natural resources that merit preservation and which would be negatively affected by development. They are identified as Open Space and Preservation/Nature Park on the system map. Recreational uses are secondary to the preservation of natural open space and the conservation functions of these areas. Compatible recreational uses include hiking, picnicking and nature study. Open space or natural park sites are typically within the high-quality natural community areas identified in the City’s Natural Resource Inventory. They should be connected by trails to the City’s Natural Resource Corridors and to other parks and will be left in a natural or semi-natural state, with minimal development. local linEar Parks, trails, corridors and ParkWays These areas are developed for 1 or more varying modes of recreational travel such as hiking, biking, horseback riding, and cross-country skiing. These features may traverse 1 or more municipality with width and length minimums varying by feature type – depending on their location within or outside right- of-way. Linear parks and trail corridors are often found adjacent to major roadways within the County or other locations where needed to link cities to components of the local or regional recreation system or community facilities such as schools, libraries, or commercial destinations. These parks may also be located in planned greenway corridors or adjacent to creeks and stream corridors to provide public access to natural features, however such development should consider site and habitat impacts. Existing city Parks The City of Corcoran owns 3 parks: The Corcoran Community Park is located at the intersection of County Roads 10 and 50. The park is approximately 16 acres. Park facilities include a playground, tennis and volleyball courts, softball fields, ice rinks, parking and a picnic shelter. The City has also begun developing park land on City Hall property. The site, including the Memorial Garden, is an estimated 8 acres. Once fully developed, this park will consist of picnic facilities and trails. The site may be used in conjunction with the adjacent community center. Draft Copy -- 2/1/2018 74 A new park has been dedicated as part of the Ravinia development and is owned by the City. A plan for development was approved but not yet built at the time of this Comprehensive Plan. The park name will be determined as part of the park development efforts. See concept below. local arEa school BallPark FiElds The Rockford School District owns approximately 60 acres abutting the west side of Corcoran Community Park. The site is developed with athletic fields and is open for use by park system patrons. The City maintains and manages the site under an agreement with the School District. Although the site was originally purchased for development of an elementary school, its future use is somewhat uncertain. Should the land become available the City would consider acquisition for expansion of the community park to the east. PrivatE Park The Corcoran Lions Club owns a multi-use facility at the intersection of County Roads 10 and 101. This the site of the Hennepin County Fair, the Hamel Rodeo and a variety of other public entertainment events. While it is a privately owned and operated open space, the City’s Goals and Policies (see Goal 2) prioritize keeping open communication with such entities to ensure cooperation and thoughtful planning of the City’s parks and trails. Parks and trails loCations Proposed parks are identified on the 2040 Parks and Trails System Map, Figure xx. Athletic complex and open space search areas are shown on this plan to indicate potential site areas, not exact property locations. These search areas are distributed throughout the community to aid further investigate for costs, ease of obtaining land, access and proximity to future growth and development. Many of these parks will be developed as new residential neighborhoods are constructed, increasing the need for parks. The City will work with developers and other landowners to identify the exact location and size of parks and trail alignments as development or park acquisition is proposed. The City will seek to co-locate trails with other infrastructure easements where feasible. Map 5-1: Parks and Trails Plan future Parks dEMograPhics/coMMunity groWth This Plan uses the population forecasts and the context presented in this Comprehensive Plan to recommend the number and distribution of park and trail facilities in the community. The National Recreation and Park Association (NRPA) has provided standards in the past for how to place parks by park type, and the general facilities you might see in each park. The NRPA is moving away from the minimum standards of service, as findings indicate that each City has unique needs, and is encouraging communities to benchmark their metrics and enter their data into the national database. Therefore, if more parkland than the minimum standards is required to serve the population in each neighborhood, the City may acquire land to meet this need. local trEnds In April 2017 the City surveyed residents regarding, “What amenities are important to you as a resident?” Key findings from 115 responses were used to guide the 2040 Parks and Trails plan, including the following: • Parks and trails within a mile of each Corcoran neighborhood was valued by 51percent. • Green spaces (i.e. open space parks) were valued by 61percent of respondents. The 2017 survey supports a trend in past community surveys (in 2008 and 2004) also indicating that the City should develop trails, parks, and green spaces for park system patrons. FuturE ProjEctions By tyPE According to NRPA standards, there should be 1 neighborhood park per 5,000 people within 1/4 to 1/2 mile of their home and 1 community park per 15,000 people within 2 miles of the residents. As Corcoran is still developing, it is important to consider the proximity of new parks to new residential developments, and how the density of the development effects the size and quantity of park types. Applying only 1 standard of park need, for example overall population, would suggest the park needs just 1 community park. However, considering just the land area of Corcoran within the 2040 MUSA line suggests the community will need nearly 10 community parks. While the overall acreage of parkland planned for Corcoran exceeds the standards set by the NRPA, not all neighborhoods have neighborhood or community parks within the recommended service areas. As population increases in each neighborhood, the City should acquire parkland in those neighborhoods to serve populations within each neighborhood. Based on review of park development trends as indicated by NRPA, the City will have a projected need of 14 acres of park land for every 1,000 residents. With this standard in mind, and considering the character and existing ecological assets within Corcoran, the following is the planned system to serve approximately 11,300 people in 2040: • Neighborhood Parks: As the City has 1 neighborhood park approved for development in Ravinia, the City will need approximately 2-3 additional neighborhood parks, totaling approximately 10-60 acres, by 2040. These parks should be located within ½ mile walking distance of significant neighborhood developments. • A new Town Square is planned in the downtown core, as part of the Corcoran Southeast District and Downtown Guidelines. The Town Square is categorized as a Neighborhood Park due to its scale and value to future downtown residents via programming. The Town Square is planned as a social center for the community, suitable for concerts and celebrations. It will be a public space to support the bustle of downtown. • Community Parks: In addition to the 2 existing community parks, the City will need 1 to 2 new community parks by 2040. These additional community parks would require approximately 20-200 new acres. • Community Playfields: The City’s playfield requirements will be affected in large part by the long-term disposition of the Rockford School District property. If the Rockford property remains available to the City, then the City would not need additional playfields by 2040. If the Rockford property is not available, the City would need to obtain approximately 20-100 acres for 1 community playfield by 2040. A 2006 TKDA Needs Analysis and Recommendations offers metro-area guidelines for population- driven facility types and this study will serve as a continuing resource in the search for and design of both an athletic complex and the other identified parks. • Open Space Parks: The City will consider adding approximately 60 acres of public open space. The space may be divided among 3 sites. • Local Linear Parks, Trails, Corridors and Parkways: See recommendations in Future Trails section that follows.

The low number in the range is the Corcoran’s 2040 parkland need with minimum areas of recommended development. Existing parks in Corcoran fall in the small side of the neighborhood and community park scale. The high end of the range is because, as earlier chapters of this comprehensive plan point out, Corcoran has an abundance of naturally occurring ecological assets. These assets are in most cases prohibited from development by environmental protection regulations. These ecological assets also support the unique character of Corcoran, a priority the community has identified as important to preserve, see Policy 4, Goal 1. Secondly, the community has also consistently conveyed the importance of maintaining the community’s “rural character’. Open space is a key feature in rural character. Recreation trends and community preferences will ultimately affect the number, size, and location of specific parks and facilities. The system master plan shows a concentration of new neighborhood parks within future neighborhoods where a density of new housing will support the need and use of those parks. The City will continue to work closely with the local school districts in future planning of play fields, athletic complexes and additional park facilities. future trails Corcoran residents have expressed a strong interest in trails, particularly for walking and biking. The community also has a high level of interest in snowmobile and horseback trails. The community’s value of trails has been implemented into this plan. New to the 2040 Metropolitan Council Transportation Policy Plan, a Regional Bicycle Transportation Network (RBTN) has been established. The RBTN seeks to integrate a seamless network of on road bikeways and off road trails to improve conditions for bicycle transportation at the regional level. Corcoran’s Trail System plan will consider connections to surrounding communities when planning on road bikeways and off road trails to support park system patrons interest in trails and the regional bicycle transportation network. There are several categories of trails identified on the 2040 Parks and Trails Plan. The City of Corcoran is continuing to plan for a fully developed system ultimately offering up to 122 miles of trails. Trail categories and potential developments are described in Figures 5-3 through 5-6: taBle 5-2: City and County trail system Within CorCoran Total Trail Miles in 2040 MUSA 60 All TypesTotal Trail Miles Outside 2040 MUSA 62 Total Off Road Miles 50 Inside & Outside MUSA Total On Road Miles 64 Total Horseback Trails 8 Total Trail System Miles 122 regional linking trail Regional linking trails are located to serve as linkages between components of the regional parks system.

The general alignment is shown on the map along County Road 19. The length of this trail through Corcoran is approximately 6 miles. This trail is considered a Tier 2 alignment in the RBTN network. A proposed regional trail (Rush Creek Regional Trail) is also planned just outside the northern edge of Corcoran providing a connection point from County Road 101 near 117 to Crow-Hassan Park Reserve. A second RBTN, Tier 2 trail is proposed for County Road 101 between Corcoran and Maple Grove. No other RBTN network connections are proposed in the Metropolitan Council’s 2040 TPP. County trail County trails, in this case proposed and managed by either Hennepin County as part of their regional bikeway system or Three Rivers Park District (TRPD) as part of their regional trail system, are often found adjacent to major roadways and locations needed to link cities and components of the local or regional recreation system and/or community facilities such as schools, libraries or commercial destinations. Three Rivers Park System has proposed a network of nearly 49 miles off road trails for Corcoran, generally aligning with Greenway Corridors. It should be noted that trail terminology varies from County to City. In this plan and in the City of Corcoran generally, terms of on road and off road trails are preferred. Hennepin County uses on street and off street terminology though they are functionally the same. on road trail This trail type is a striped or signed bikeway on an existing road right-of- way or designated lane. The City has 1 4.5-mile on road trail along County Road 30 and 1 6-mile trail along County Road 116. By 2040, the City on road trail system is planned to include 31 miles; another 33 miles of on road trails are planned outside the MUSA. off road trail An off road-trail is a multi-use trail, paved or gravel that is at least 8 feet wide. These trails are designed for bicycle, pedestrian, and other non- motorized uses. The City and County agencies combined are planning for approximately 49 miles of off road trails, 26 miles inside the 2040 MUSA and 23 miles outside that area. The City is investigating the possibility of co-locating an off-road trail over the natural gas pipeline easement in the southern half of the City.

The plan also identifies policies and planned actions to meet those transportation needs. The transportation chapter identifies the City of Corcoran goals and policies and describes the existing and future transportation system. The impact on transportation systems and the responsibility for improvements to the system are a State, County, and City issue. While the City of Corcoran must provide the resources to accommodate transportation demands that coincide with its land use decisions and population growth, increased traffic from the growth of neighboring communities are also part of the traffic demand. The County and State share the responsibility of providing safe and efficient transportation through the City of Corcoran. Corcoran is designated partially as an Emerging Suburban Edge community in the Metropolitan Council’s Thrive MSP 2040 plan. The planning area sets overall densities that the planned development patterns in the community can be expected to achieve. There are many land use decisions that are tied to roadway improvements. Some land uses are not appropriate without adequate transportation facilities. The issue of what occurs first, development or the systems to support it, will be critical as it relates to transportation needs. Coordination of the infrastructure will be necessary to create a system that works to support the land uses both in and surrounding Corcoran. As the City develops, focus should be on protecting natural resources, ensuring sufficient public infrastructure, and developing transition strategies to increase density and encourage infill development. transPortation goals and PoliCies Goal 1: Improve the transportation network for local and pass-through traffic. Policy 1: Provide a comprehensive transportation system based upon functional classification of roadways that fully promotes connectivity and is coordinated with neighboring cities and counties. Policy 2: Identify a transportation system that efficiently moves traffic, minimizes traffic conflicts as development occurs, and is consistent with MnDOT, Hennepin County, neighboring communities, and the City’s land use plan. Policy 3: Identify long-term planning for transportation corridors to manage access and capital improvements as development occurs. Policy 4: Study the alignments of County Road 10 and County Road 50 represented on the Transportation Plan to improve the geometric configuration and align with the long-range City land-use plan. Policy 5: Fund a Capital Improvements Program to ensure long-term street maintenance and reconstruction programs. Policy 6: Plan and design transportation facilities that preserve natural resources and existing infrastructure where applicable. Policy 7: Pave appropriate public gravel roads deemed necessary by the City as circumstances such as development, regional improvements, City needs, or other dictate, subject to financial feasibility and funding availability. Goal 2: Ensure that planned transportation infrastructure, capacity, and access will accommodate proposed land uses and development. Policy 1: Incorporate the use of innovative traffic management options and technologies. Coordinate transportation planning and system improvements with other government jurisdictions. Policy 2: Comprehensively coordinate all transportation-related facilities as 1 system. Policy 3: Incorporate land uses and access spacing guidelines compatible with the functional classification of the regional highway system. Policy 4: Develop all additional elements of the street system (sidewalks, trails, lighting, landscaping, etc.) harmoniously with adjacent land uses and transportation objectives. Goal 3: Incorporate elements in development standards related to bicycle and pedestrian uses. Policy 1: In all residential and mixed-use areas, identify future pedestrian, trail, and bicycle facilities to connect neighborhoods with major commercial and park and recreational areas. Policy 2: Design arterial highways in the City to prevent unregulated pedestrian and bicycle crossings and to protect pedestrian and bicycle movement paralleling vehicular traffic. Additional information regarding the trail system in Corcoran is provided in Chapter 5. suPPort and rationalE For transPortation goals and PoliciEs The concern over regional traffic on the City’s road system can be managed internally to an extent. By providing a local street system that relies on internal connections between neighborhoods, local conflicts with regional traffic can be avoided in many instances. Where multiple trip options exist, traffic impacts on any 1 location are minimized. However, when traffic is concentrated to only a few practical routes, traffic conflicts affect everyone. Subdivision design will be required to include internal connections wherever possible. The City expects that new development will be designed with sufficient traffic planning improvements and those impacts on the system will be kept to those routes that are properly intended for increased traffic levels. These goals and policies also carry an expectation that the City will work actively with its neighboring communities and other highway jurisdictions to improve traffic management on all routes through the City. At the same time, Corcoran expects that transportation planning respects the City’s other planning goals and designs roadways that enhance the environment of the community. This may mean innovative design techniques or routing of traffic to preserve sensitive areas. The City will work with all jurisdictions to ensure the accomplishment of both traffic needs and the City’s land use goals. On a community-wide basis, pedestrian movement is likely to be more recreational in nature. The predominant rural development pattern does not lend itself to reliance on walking or bicycling for daily commerce. However, the development of trail systems is a popular recreational attraction. The retrofitting of existing development areas and the design of new development areas (both urban and rural) with trail systems, bike ways, and sidewalks will be an important improvement for the community. With the higher level of development activity envisioned by this Plan, roadway design and access will play a more important role in locating new development. The urban districts delineated in the land use plan are to be served by major collector or arterial roadways. New urban development within those districts will need to demonstrate more than the mere availability of utility services, or avoidance of natural resource areas. The potential for loading significant amounts of new traffic onto the City’s street and highway system will require attention to the capacity of the higher function roadways serving the project area. In some areas, construction of new collector streets may be required as a pre-condition for approval of a new subdivision where it is not possible to mitigate “downstream” traffic impacts. Access management is a key to controlling the impacts of new traffic generation and avoidance of congestion. Moreover, direct access to major streets (regardless of jurisdiction) has significant land use impacts in the creation of conflicts, increasing crash statistics, and decreasing land values. Corcoran will actively implement access management policies throughout the City and will require all subdivision design to comply with the highest thresholds of transportation planning. 2018 existing transPortation system Transportation elements are divided into several sub-categories, each of which is an important piece of the overall transportation system. Several sub-categories are further divided into existing and 2040 conditions. highWays and strEEts roadWay jurisdiCtion Roadways are categorized under the agency that is responsible for their maintenance. The State is responsible for the Federal Interstate, US Highways, Minnesota Trunk Highways (TH), and State Park Roads. The County is responsible for County State-Aid Highways (County Road) and County Roads (CR). Other roadways, including Municipal State-Aid Streets and municipal roads are the responsibility of the City of Corcoran. Map 6-1 shows the current jurisdiction for the area roadways.

Roads are categorized based upon the level of access and mobility provided. Functional classification of a roadway system involves determining what function each roadway should be performing with regard to travel within and through the City. The intent of a functional classification system is the creation of a roadway hierarchy that collects and distributes traffic from local roadways and collectors to arterials in a safe and efficient manner. Such classification aids in determining: • Appropriate roadway widths • Speed limits • Intersection control • Design features • Accessibility • Maintenance priorities Functional classification helps to ensure that non-transportation factors, such as land use and development, are considered in planning and design of the roadway system. A balanced system is desired, yet not always attainable due to existing conditions and characteristics. The criteria of the functional classification system are intended to be guidelines and are to be applied when plans are developed for the construction or reconstruction of a given classified route. It can, and does, occur that different roadways with very similar design characteristics may have different functional classifications. Some roadways, for a short segment, may carry higher volumes than a roadway with a higher classification. Spacing guidelines may not follow recommendations for a variety of reasons such as topography, environmental concerns, and land use type and density. The 2 major considerations in the classification of roadway networks are access and mobility. Mobility is of primary importance on arterials, thus the limitation of access is a necessity. The primary function of a local roadway, however, is the provision of access, which in turn limits mobility. The extent and degree of access control is a very important factor in the function of a roadway facility. The functional classification types utilized are dependent upon 1 another in order to provide a complete system of streets and highways. The relationship of functional classification regarding traffic mobility and land access is shown below in Figure 6-1. A complete functional design system provides a series of distinct travel movements. Most trips exhibit 6 recognizable stages. These stages are as follows. • Main movement • Transition • Distribution • Collection • Access • Termination As an example, Figure 6-2 below depicts the hierarchy of movement by illustrating a hypothetical trip using a freeway, which comprises the main movement. When the vehicle leaves the freeway, the transition is the use of the freeway ramp at a reduced speed. The vehicle then enters the moderate speed arterial, the distribution function, to travel toward a neighborhood. From the arterial, the vehicle enters a collection road then a local access road that provides direct approach to the residence or termination point. Each of the 6 stages of the trip is handled by a facility designed specifically for that function. Speeds and volumes normally decrease as 1 travels through the 6 stages of movement. It must be recognized that not all intermediate facilities are needed for various trip types. The character of movement or service that is provided has a function and these functions do not act independently. PrinCiPal arterials Principal arterials carry a higher proportion of total urbanized travel on a minimum of mileage. They also serve major activity centers, higher traffic volumes, and longer trips. Along these facilities, access needs to be limited in order to preserve the ability of the roadway to accommodate the volumes and to maximize safety. Principal arterials emphasize mobility over land access. Little or no direct land access should be allowed within an urban area. The management criteria require that a 40-mph average speed be achieved during peak traffic periods. Grade separated intersections are required for freeways and are highly desired for other principal arterial roadways. In the Metro area, interstate freeways are classified as principal arterials. TH 55 is a principal arterial within the City of Corcoran. PICTURE PLACEHOLDER PICTURE PLACEHOLDER Figure 6-1 Figure 6-2 Draft Copy -- 2/1/2018 85 minor arterials Minor arterial roadways connect the urban service area to cities and towns inside and outside the region and generally service medium to short trips. Minor arterials connect principal arterials, minor arterials, and collectors. The spacing ranges from 1/4 to 3/4 of a mile in metro centers to 1 to 2 miles in a developing area. The desired minimum average speed during peak traffic periods is 20 mph in fully developed areas and 30 mph in developing areas. The emphasis for minor arterial roadways is on mobility rather than land access. In urban areas, direct land access is generally restricted to concentrations of commercial/industrial land uses. Minor arterials generally serve medium to short trips and provide use for local and limited stop transit service. Minor arterials are divided into “A” minor arterials and “B” minor arterials. “A” minor arterials are roadways that are of regional importance because they relieve, expand, or complement the principal arterial system. “A” minor arterials are categorized into 4 types, consistent with Metropolitan Council guidelines: Relievers Minor arterials that provide direct relief for metropolitan highway traffic. There are currently no “A” minor arterial relievers within the City. Expanders Routes that provide a way to make connections between urban areas outside the I-494/I-694 beltway. County Road 101 is an example of an “A” minor arterial expander within Corcoran. Connectors Roads that provide connections to and among communities at the edge of the urbanized area and in rural areas. County Road 50, County Road 30, and County Road 19 are examples of an “A” minor arterial connector in Corcoran. Augmenters Roadways that augment principal arterials within the I-494/I-694 beltway. There are currently no augmenters within Corcoran. A well-planned and adequately designed system of a principal and “A” minor arterials will allow the City’s overall street system to function the way it is intended and will discourage through traffic from using residential streets. Volumes on principal and minor arterials roadways are expected to be higher than on collector or local roadways. “B” minor arterials provide a city-wide function, serving medium to long distance trips. There are currently 2 “B” minor arterials within the City, County Road 116, and County Road 117 (109th Avenue North). ColleCtor streets Collector streets provide more land access than arterials and provide connections to arterials, although not in all cases. As is the case with any roadway system, there will always be exceptions to the planning guidelines that are used to classify a roadway system. Collectors serve a dual function of accommodating traffic and the provision of more access to adjacent properties. Mobility and land access are equally important and direct land access should predominately be to development concentrations. Collector road spacing ranges from 1/4 to 3/4 of a mile in a fully developed area, and 1/2 to 1 mile in a developing area. Collectors can be broken down further into major and minor collectors. Major collectors generally connect to minor arterials and serve shorter trips within the County or City. These roads supplement the arterial system in that mobility is slightly emphasized over access. An example of a major collector within Corcoran is County Road 10. Minor collectors provide the connection between neighborhoods and commercial/industrial areas and the major collector/minor arterial system. Access is slightly emphasized over mobility in minor collectors. Oakdale Drive, Trail Haven Road, Kalk Road, and Willow Drive are examples of minor collectors within the City. loCal streets The lowest classification of roadways is the local roadway where access is provided with much less concern for control, but land service is paramount. Spacing for local streets is as needed to access land uses. Local roadways generally have lower speed limits in urban areas and normally serve short trips. Local streets will connect with some minor arterials but generally connect to collectors and other local streets. The development of local streets will be guided by the location of the existing and proposed minor arterials and collectors as well as by development and the expansion of local utilities. Abilene Lane, Foxline Drive, Horseshoe Bend Drive, Jackie Lane, and Sundance Road are examples of local streets.The existing roadway functional classification system is shown on Map 6-2. Map 6-2: Existing Roadway Functional Classification accEss ManagEMEnt guidElinEs The management of thoroughfare access along roadway systems, particularly arterial and collector roadways is a very important component of maximizing the capacity and decreasing the crash potential along those roadway facilities. As mentioned in a previous section, arterial roadways have a function of accommodating larger volumes of traffic and often at higher speeds. Therefore, access to such facilities must be limited in order to protect the integrity of the arterial function. Collector roadways provide a link from local streets to arterial roadways and are designed to provide more access to local land uses since the volumes and speeds are often less than arterial roadways. Studies have shown that as the density of access increases, whether public or private, the traffic-carrying capacity of the roadway decreases and the vehicular crash rate increases. Businesses suffer financially on roadways with poorly designed access, while well-designed access to commercial properties support long-term economic vitality. As with many transportation related decisions, land use activity and planning are an integral part of the creation of a safe and efficient roadway system. Every land use plan amendment, subdivision, rezoning, conditional use permit, or site plan involves access and creates a potential impact to the efficiency of the transportation system. Properties have access rights and good design will minimize the deleterious effect upon the roadway system. Minnesota State Statutes state that “reasonable, convenient, and suitable” access to property shall be provided. Access management is a combination of good land use planning and effective design of access to property. The granting of access is shared by the State, County, and City with each having the permitting process responsibility over roadways under their control. The aforementioned authorities may also require the following while examining access: • Dedication of public rights-of-way • Construction of public roadways, trails, and bikeways • Mitigation measures of traffic and/or other impacts • Change in and/or development of new access points • Dedication of trail easements Using proper access guidelines helps all the agencies involved act in a coordinated manner. However, access spacing is important not just for new developments but for existing developments and accesses as well. Processes should be developed to deal with existing corridors that have allowed improper access spacing in the past. In these cases, it is possible that the number of access points exceed the access spacing guidelines. These existing access points must be handled in a different manner than with new access points. It is desired to aggressively minimize any new accesses while consolidating, restricting, and/or reducing existing access points as redevelopment occurs. It is important to remember that access spacing guidelines are long term goals and not absolute rules. Maintaining flexibility is important when promoting access consolidation, including consideration of existing conditions, physical barriers, or constraints. The traveling public benefits from access spacing whether using grade-separated crossings, frontage roads, right-turn only entrances/ exits, etc. Given the number of agencies potentially involved in reviewing plats and access points, access guideline and corridor management practices should be implemented at the State, County, and City level. MnDOT has developed guidelines for access management based upon their goals of safety, mobility, and statewide growth. As a part of their guidelines, 4 new categories were developed as an addition to the functional classification system: • High Priority Interregional Corridors (IRC) • Medium Priority IRC • Regional Corridors • Statewide Roads These types of roadways link the State’s primary trade centers and the Twin Cities Metro area to 1 another. MnDOT has further divided the primary categories into sub- categories based upon the specific facilities and land use patterns surrounding the roadway. TH 55 is recognized as a regional corridor. The governmental unit controlling specific roadways also controls access to these roadways. For the most up-to-date access spacing guidelines, contact MnDOT and Hennepin County.

Map 6-4 shows the existing average annual daily traffic (AADT) volumes within the City. The traffic volumes shown in Map 6-4 are used as a planning tool to help test the ability of a roadway to accommodate future volumes. In addition to the number of lanes provided, the daily capacity of any individual roadway is based upon many factors including: • Number of access points per mile • Number of signalized intersections per mile • Percentage of truck traffic • Physical grade of the roadways Map 6-4: Existign Annual Average Daily Traffic Volumes (ADT) Level of service (LOS) is a qualitative measure describing operational conditions within a traffic stream, generally in terms of service measures such as: • Speed and travel time • Freedom to maneuver • Traffic interruption • Comfort and convenience Six levels, LOS A to LOS F, are generally used for traffic analysis. LOS A is the best with free flow conditions and little to no delay. LOS F is the worst with congestion, long delays, and forced flow.

The section was compiled from several sources including: • TH 55 Corridor Coalition • Hennepin County Transportation Systems Plan (HC-TSP) • Comprehensive Plans from surrounding communities • Corcoran’s Vision Some of the issues have been identified on Map 6-5. The City of Corcoran may or may not support all the issues that are discussed in the following section, but the issues have been discussed by others and may affect Corcoran. Map 6-5: Trasportation Issue Areas highWay 55 corridor TH 55 is a primary transportation corridor linking the western communities in Wright County and Hennepin County to the Minneapolis/St. Paul Metropolitan area. The corridor has become congested as the area has developed because there are no parallel routes to spread the traffic demand. Therefore, the capacity of TH 55 must be increased. The increasing traffic and capacity needs are a growing concern to the communities along the corridor. Direct access to TH 55 and crashes along the corridor have raised the concern for the safety of everyone who uses the highway. MnDOT is currently faced with growing transportation needs throughout the State and decreasing transportation funding. The TH 55 Corridor Coalition has prepared a concept improvement plan for TH 55. This plan proposes the provision of an improved facility with the potential of interchanges at County Road 101 and County Road 116. The plan proposes TH 55 to be a 6-lane divided roadway from the City of Medina to County Road 116 in Corcoran and then a 4-lane divided highway from County Road 116 to County Road 19. The concepts developed within this corridor plan are a guide to help preserve future right- of-way along the corridor. Funding does not exist to construct any of the recommended improvements at this time. county road 10/county road 50 rEalignMEnt Although the 10/50 intersection was realigned in 2017 by Hennepin County, the intersection geometrics remain poor due to the angle County Road 10/County Road 50 form as they intersect. To date, an ultimate design or project schedule for the intersection has not been determined by Hennepin County. The City’s largest municipal park is also located near the 10/50 intersection area. nW hEnnEPin county transPortation iMProvEMEnts The Northwest Hennepin County – I-94 Sub-Area Transportation Study (NW Hennepin Study) was completed in April 2008. The study was initiated to identify future transportation system needs, to address the changing needs within those communities, and to establish the groundwork for moving forward with requests for additional access to I-94. Through the study, some key issues were identified including a lack of an arterial roadway system in the area, physical constraints, congestion, and access to I-94. The study identifies an area south of I-94, which includes Corcoran, as an area that lacks an arterial roadway system. Traffic volume forecasts for the year 2040 were developed based on Metropolitan Council projections of population, households, and employment. The study area roadway’s capacities and deficiencies were identified so that communities can plan for additional capacity improvements or manage facilities effectively through access controls, right-of- way preservation, setback requirements, and/or land use and development controls. Improvements identified in the study were based on transportation system needs and growth trends with no account for available funding. Implementation priorities were established using the following criterion: • Improving system connectivity to provide better east-west and north-south flow in immediate growth areas; • Addressing current capacity issues at major intersections/ interchanges and overloaded segments; • Addressing I-94 access issues to better balance access to I-94; • Leveraging funding of federal, state, local, and private funds to the fullest extent. county road 30 The City plans for County Road 30 is to be the primary east-west corridor through Corcoran in the future. The extension of County Road 30 east of Corcoran will connect to the future TH 610 interchange at I-94. Eventually, County Road 30 will be a 4-lane facility through Corcoran. The City plans for County Road 30 to be designed as a parkway through the City. Future development may need to provide larger right-of-way to accommodate a parkway design.

The NW Hennepin Study examined an interchange at the Brockton Lane area due to spacing from other I-94 access points as well as connections to the arterial roadway system. This proposed regional access to I-94 serves to relieve adjacent interchanges, increase system efficiency and safety, and relieve overloads on other local system linkages. If access to I-94 in the Brockton Lane area is not provided, significant capacity enhancements to arterials and interchanges at TH 101 in Rogers and County Road 30 in Maple Grove would be needed. rivEr crossings The potential need for a new Crow River crossing was raised by the Wright County Transportation Plan in 1994, but was seen as being beyond the study period in the Hennepin County Transportation Systems Plan (HC-TSP). This potential link would extend County Road 30 in Hennepin County westerly to Wright County Road 144, thus providing an east-west connection between Buffalo to TH 610. The impacts of this river crossing are still being examined. The exact alignment of the County Road 30 extension and the river crossing has not yet been determined and will require further detailed study. transit system There currently are no public transit facilities or services in the City of Corcoran. As growth and development occur in the community it will be important to include transit options in designs. Park and Ride or carpool areas should be accommodated in site development or on public sites. Streets or parking lots can be designed with pull over locations to accommodate bus stops that do not impede traffic flow. While the City does not have public transit at this time, other types of transit solutions should not be ignored and should be explored. Corcoran is currently designated as the Metropolitan Transit Market Area V. Transit Market Area V has very low population and employment densities and tends to be primarily rural communities and agricultural uses. General public dial-a-ride service may be appropriate here, but due to the very low- intensity land uses these areas are not well-suited for fixed-route transit service. Figure 6-3: Transit Market Area V Source: Metropolitan Council FrEight There are no railroad facilities, barge facilities, or intermodal freight terminals within the City of Corcoran. Most truck traffic on TH 55 is passing through Corcoran to locations within the metro area. Data from MnDOT indicates a Heavy Commercial Average Annual Daily Traffic volume of 500-999 vehicles per day on TH 55 in Corcoran. Other roadways in Corcoran carry significantly lower heavy commercial volumes, with most trips made for delivering goods to local businesses. aviation FacilitiEs There are currently no public aviation facilities in the City of Corcoran. However, the City is within the region’s general airspace which needs to be protected from potential obstructions to air navigation. Under Minnesota Statutes 360, the State regulates the height of structures as they are defined and enforced under Aeronautics Rules and Regulations 8800.1200 Criteria for Determining Air Navigation Obstructions. Subparagraph 4(B) states: Objects more than 200 feet above the ground or more than 200 feet above the established airport elevation, whichever gives the higher elevation, within 3 nautical miles of the nearest runway of an airport, and increasing in the proportion of the 100 feet for each additional nautical mile of distance from the airport but not exceeding 500 feet above ground, is a general obstruction. Notification to MnDOT Aeronautics is required when any object, as defined above, would affect general airspace. The City will include the following requirements with all applications: Notification: Any applicant or property owner who proposes any construction or alteration that would exceed a height of 200 feet above ground level at the site, or any construction or alteration of greater height than an imaginary surface extending upward and outward at a slope of 100:1 from the nearest point of the nearest runway of a public airport shall notify the Commissioner at least 30 days in advance. Local reporting is in addition to any Federal permitting/review process (FAA Form 7460-8) involving a sponsor/ proposal. Bicycling and Walking The existing and planned on-road and off-road bicycle facilities are shown in Map 5-1. In the 2040 Met Council Transportation Policy Plan, County Road 19 and County Road 101 are classified asTier 2 alignments for bicycle facilities. No other alignments or corridors are planned in Corcoran. As the area develops, enhancing the non-motorized facilities within Corcoran will be important in order to improve transportation sustainability within the City. Improved facilities and connections provide alternatives to driving, support options for residents who do not have a personal vehicle, and promotes healthy lifestyles and exercise. The City’s integrated transportation network will include appealing and safe streets that are accessible to people walking and biking, as well as people driving motor vehicles. A combination of off-road and on-street bike and pedestrian facilities are included to give people safe and convenient options for active transportation. 2040 future transPortation system highWays and strEEts 2040 traffiC ProjeCtions Year 2040 annual average daily traffic (AADT) forecasts were developed using data provided by the Metropolitan Council from the travel demand model. Future AADT for the roadways in Corcoran were projected based on the future land use, TAZ data, and population growth estimates. The volumes shown are generally lower than 2030 forecasts presented in the Hennepin County transportation plan. Those forecasts were developed in the 2005-2007 time frame, when development pressure in this area was higher. Since the 2030 volumes were developed, the Metropolitan Council has shifted regional growth to urban and developed areas, resulting in lower population and employment forecasts for Corcoran. The 2040 AADT volume forecasts are shown in Map 6-6. Map 6-6: 2040 Average Daily Traffic Volumes Jurisdictional Transfers (Planned or possible) The 2030 Hennepin County Transportation Systems Plan (HC-TSP) suggests turning County Road 10 and County Road 101 back to the City. The City does not support these turn backs. The decision has not been finalized and no timeframe has been designated.The City is continuing to work with Hennepin County to determine the feasibility of these possible changes. Functional Classification Changes (Planned or possible) According to the 2030 Hennepin County Transportation Systems Plan (HC-TSP), County Road 116 and County Road 117 through Corcoran could warrant a change in either their functional classification or funding designation. These roadway segments should be monitored. The City of Corcoran should communicate with Hennepin County and the Metropolitan Council regarding any changes in either functional classification or funding designations that may arise. CounTy road 116 (Southern NW Hennepin Study Area Boundary to County Road 13) County Road 116 from the southern boundary of the NW Hennepin Study area to County Road 13 is recommended to be upgraded from a “B” Minor Arterial to an “A” Minor Arterial Reliever. This route provides important north-south continuity within the area to more urbanized metro areas to the south. In addition, County Road 116 is proposed to be extended as an overpass from Territorial Road to County Road 13. This overpass will play a similar role to County Road 117 in terms of providing local traffic circulation without congesting the busy interchange areas.

This route helps provide east-west continuity in the area. This route provides connectivity into Wright County and through an extension to the east across I-94 will provide connectivity to County Road 81 and industrial/commercial areas along County Road 81. Therefore, this section of County Road 117 is recommended to be classified as an “A” Minor Arterial Connector due to its connectivity, spacing from County Road 30 and connection to other proposed north-south minor arterials such as County Road 116 and County Road 101. County road 30 extension (County Road 19 to the west study area boundary) Currently, County Road 30 is designated as an “A” Minor Arterial Connector from I-94 to County Road 19. The future local system plan identified a continuation of this route to the west into Wright County. This route is anticipated to be the main east-west mobility corridor as it serves Corcoran, Rogers as well as traffic from Wright County through a future crossing of the Crow River. At I-94, County Road 30 is planned to be realigned in the future to connect as the western leg of the I-94/TH 610 interchange. Due to the importance of this route as a mobility corridor, it is recommended by the study to be classified as an “A” Minor Arterial Expander.

No improvements were assumed to the roadway network, with the exception of TH 55. TH 55 was analyzed as a 4-lane segment with left and right turn lanes. It can be seen from these results that improvements may be necessary at some locations to avoid undesirable levels of service. Improvements such as adding left and right turn lanes at major intersections will improvement the overall level of service for roadway sections by decreasing delays and improving traffic flow. Corcoran will continue to monitor traffic operations and pursue improvements at locations when necessary to provide acceptable levels of service.

Hennepin County has identified improvements that were used in their Base 2040 Roadway Network. This itemized list of improvements includes projects that are anticipated to be implemented by 2040 due to their inclusion in CIP’s, the Transportation Improvement Plan (TIP) or some action that makes the improvement likely.

PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 107 On May 28, 2014, the Metropolitan Council adopted an updated 2040 Water Resources Policy Plan (WRPP). The 2040 WRPP includes the metropolitan wastewater system plan with which local comprehensive plans must conform. The intent of this chapter is to describe Corcoran’s existing and proposed ultimate wastewater collection and disposal system and to demonstrate Corcoran’s conformance with Metropolitan Council wastewater system planning, providing specific information needed to meet the 2040 WRPP requirements. Metropolitan Council’s Environmental Services Division (MCES) operates the Metropolitan Disposal System (MDS) that will ultimately provide wastewater service to the sewered portions of Corcoran. The MDS includes interceptor sewers, lift stations, forcemain, wastewater treatment plants, and other features necessary for the Metropolitan Council to operate a regional wastewater collection and treatment system. Corcoran currently has 2 connections to the MDS, 1 that is currently in use in the SE District and 1 that was recently constructed to the NE District that has not yet been utilized by the City. This section provides Corcoran’s projections for wastewater flow increases that Metropolitan Council can use for regional wastewater planning purposes, including whether capacity upgrades will be needed at the Metropolitan Wastewater Treatment Plant (WWTP). The updated wastewater section reflects updated land use plans from what was envisioned in the City’s 2030 Comprehensive Plan. goals and PoliCiesGoal 1: Construct the system including truck and local collectors as development takes place within the City. Policy 1: Require developes to construct a system in a size and manner to support future needs of the system.Policy 2: Extend the system to adjacent properties as development takes place. Goal 2: Operate in an efficient and sanitary manner to protect public health, safety and welfare, to safeguard municpal finances, and to support development and economic vitality within the community Policy 1: Implement preventative maintenance programs to protect and sustain the system.Policy 2: Restrict the installation and use of individual sewage treatment systems when necessary or appropriate. metroPolitan CounCil interCePtor ConneCtions Metropolitan Council has identified 3 connections to the MDS, 2 existing connections via the Elm Creek Interceptor and 1 future connection via the Maple Plain Interceptor. Corcoran’s planned service areas to each of the MDS connections are as follows: • Southwest (SW) Corcoran Connection at Node SW-5 This connection will serve SW Corcoran with connection to the Maple Plain Interceptor via Loretto. Forcemain construction from SW-5 to an unspecified location was assumed, though potential gravity connection should be explored as the details of an MCES extension to SW Corcoran become clearer. • Southeast (SE) Corcoran Connection at MCES Regional Lift Station L-80 This connection will serve the eastern portion of SE Corcoran via the South Corcoran Extension of the Elm Creek Interceptor. Construction of the gravity sewer (15-inch) portion of the extension has been completed to the Corcoran border at County Road 10, and the L-80 lift station will begin operation in 2018. With the 2017 connection of the downtown area, until the L-80 lift station is operational, the MCES is implementing temporary wastewater pumping/hauling (i.e., this wastewater is allowed to accumulate in the City’s 15-inch gravity sewer upstream of a plug installed near Node SE-22). • Northeast (NE) Corcoran Connection at Node NE-18 (MCES Meter Station M310) This connection will serve NE Corcoran (and eventually also the western portion of SE Corcoran via diversion of wastewater to NE Corcoran). Construction of this meter station at the very NE corner of Corcoran was recently completed by MCES, providing access to the Rogers/Northeast Corcoran Leg of the Elm Creek Interceptor. The City has not yet constructed any sanitary sewer from the meter station, but discussions with a developer for the first connecting development have occurred. Corcoran’s existing sanitary sewer is shown on Map 7-1. Map 7-1: Existing Sanitary Sewer Corcoran’s proposed trunk sanitary sewer system and the 3 proposed connection points to the MDS are identified on Maps 7-2 through 7-4. The facilities identified on Map 7-1 are designed to serve the City through the 2040 forecasts for growth, shown in Table 7-1. There is potential for expansion as as the City continues to grow allowing for system capacity increases. Actual growth rates will generally affect only the timing of trunk sewer construction and not the design of the system, i.e., an ultimate trunk system based on full development of the depicted service areas has been designed.

The Metropolitan Council uses these forecasts to plan all future interceptors and wastewater treatment work needed to provide adequate service. Table 7-3 presents average wastewater flow projections for Corcoran, as provided in the Metropolitan Council’s 2040 WRPP. The flow projections are based on the forecasts provided in Table 7-2, using 60 gallons per day per sewered resident and 15 gallons per day per sewered employee (these values are utilized for new development). taBle 7-3: average WasteWater floW ProjeCtions Year Average Wastewater Flow Projections (MGD) 2010 0.00 2020 0.08 2030 0.17 2040 0.21 Table 7-3: Average Wastewater Flow Projections It should be noted Corcoran recognizes the wasterwater flow projections shown in Table 7-3 could be underestimated. While Corcoran agrees with the Metropolitan Council’s projection of approximately 110 new homes (sewered plus unsewered) per year being added in Corcoran between 2020 and 2040, Metropolitan Council’s assumption that only 50 percent of those homes will sewered, from 2020 to 2030, and only 30 percent will be sewered from 2030 to 2040, is an incorrect estimate based on current development trends in Corcoran. Projections currently show at least 90 percent of the new homes constructed from 2020 through 2040 will be sewered, with approximately 100 sewered home likely added per year. For reference, using 100 sewered homes per year would increase the average wastewater flow projections to 0.22 MGD in 2030, and 0.36 MGD in 2040. Table 7-4 presents the average wastewater flow projections identified in Table 7-3, split by connection point to the MDS, and with the corresponding MCES wastewater treatment plant (WWTP) location shown for reference. The locations of these connection points are identified on Maps 7-2 through 7-4. The projections for the Blue Lake WWTP southwest Corcoran versus the Metropolitan WWTP in southeast and northeast Corcoran combined were provided in the Metropolitan Council’s 2040 WRPP. The additional breakdown between southeast and northeast Corcoran reflects the City’s anticipated split between these 2 areas. taBle 7-4: average WasteWater floW ProjeCtions By mds ConneCtion Year SW Connection (MGD) SE Connection (MGD) NE Connection (MGD) Total Projected Average Flow (MGD) Blue Lake WWTP Metropolitan WWTP Metropolitan WWTP 2010 0.00 0.00 0.00 0.00 2020 0.00 0.07 0.01 0.08 2030 0.00 0.14 0.03 0.17 2040 0.001 0.17 0.04 0.21 trunk sanitary seWer system design land usE Corcoran’s 2040 Land Use Plan serves as the basis for the development of the City’s trunk sanitary sewer system by estimating volumes of wastewater generated by each land use type. Detailed descriptions of the various land uses including density ranges can be found in the land use chapter. Appendix A presents Corcoran’s 2040 land use information split by sewer sub-district within the sewered portions of the City. Corcoran’s sewer sub- district boundaries are shown on Maps 7-2 through 7-4. EstiMatEd avEragE WastEWatEr FloWs Municipal wastewater is made up of a mixture of domestic sewage, commercial and industrial wastes, groundwater infiltration, and sometimes surface water inflows. With proper design and construction, groundwater infiltration and surface water inflows, commonly referred to as infiltration/ inflow (I/I), can be minimized. However, while Corcoran intends to minimize I/I into the trunk system, to be conservative a small amount of I/I (reflecting estimated I/I contributions into a new trunk sanitary sewer system) is included in the analysis and design of Corcoran’s trunk sewer system to provide an appropriate level of service to Corcoran. ! ! ! ! !! ! !! ! !H !H !H!H !H !H !H !H !H !H !H !H !H Forcemain to MaplePlain Interceptor via Loretto City of Greenfield City of Medina ScottLake JubertLake Horseshoe Trl County Road 19 Pioneer Trl HorseshoeBendDr ChestnutDr Rolling Hills Rd KimberlyL n Wagon Wheel Ln County Road 50 65th Pl N Homestead Trl Winchester Trl JubertLn SW-A SE-AG SW-K SW-J SW-I SW-L SW-F SW-G SW-D SW-E SW-C SW-B SW-H SW-R SW-M SW-P SW-Q SW-N SW-O SW-9 SW-10 SW-11 (LS) SW-12 SW-13 SW-1 SW-2 SW-3 SW-4 SW-5(LS) SW-6 SW-7(LS) SW-8 16'' 2 4'' 8" 8" 18" 1 2 " 10" 12"15" 8'' 12" 12" 15" 456719 456750 2040 COMPREHENSIVE PLAN 1,100 0 1,100550 Feet ± Path: L:\2294\100\2040CompPlan\SW Proposed Trunk Sanitary Sewer.mxd Date: 2/1/2018 Time: 7:05:31 AM User: shujc0243 !Proposed Gravity !Proposed Gravity (Lateral)Proposed Forcemain !H Sewer Nodes (LS) = Lift StationSewer SubdistrictsMunicipal Boundary2040 MUSAParcel BoundariesStreamsLake/Open Water Map 7-4Proposed Trunk SanitarySewer System - SW District Draft ! ! ! ! ! ! !! !! ! ! ! !! ! ! ! ! ! ! ! !! ! ! ! ! ! ! ! ! ! ! ! ! ! !H !H !H !H !H !H !H !H !H !H !H !H !H !H !H !H !H !H !H!H !H !H !H !H!H !H !H !H !H !H !H !H !H !H !H !H !H!H #* Lift Station 2 and Existing Forcemain will not be neededin Proposed Condition City of Maple Grove City of Medina MorinLake GooseLake County Road 116 Horseshoe Trl B r i dl e Path AbileneLn Homestead Trl C o u n ty R oa d 1 0 County Road 50 Gleason Pkwy Willow Dr Hunter Rd Corcoran Tr l W Maple Hill Rd Mohawk Dr Trail Haven Rd Larkin Rd Cain Rd O ld S ettlers R d Kalk Rd Meister Rd Schutte Pl Strehler Rd Blue Bonnet Dr South F o r k R u s h C re ek SE-A SE-A SE-O SE-AO SE-AP SE-AQ SE-AT SE-ASSE-AR SE-D SE-K SE-M SE-C SE-I SE-H SE-B SE-FSE-E SE-G SE-N SE-T SE-L SE-S SE-J SE-R SE-Q SE-P SE-AM SE-V SE-ZSE-Y SE-U SE-X SE-W SE-AESE-AJ SE-AC SE-AB SE-AD SE-AA SE-AK SE-AU SE-AV SE-AISE-AHSE-AG SE-AF SE-18 SE-36(LS) SE-37 SE-1 SE-2 SE-3 SE-4 SE-5 SE-6 SE-7SE-8 SE-9 SE-10 SE-11 SE-12 SE-13 SE-14 SE-15 SE-16 SE-17 SE-19 SE-20 SE-21 SE-22SE-23 SE-24 SE-25 SE-26 SE-27 SE-28 SE-29 SE-30 SE-31 SE-32 SE-33 SE-34 (LS) ElmCreekInterceptor SE-35 MCESLiftStation 12'' 15'' 6'' 18'' 8'' 18'' 8'' 1 2'' 8 '' 15'' 8'' 1 2 '' 10'' 15" 6'' 8'' 15" 10'' 1 8 '' 18'' 15'' 30'' 15'' 18'' 12 " 10'' 12'' 15'' 12'' (10''Eq) 8'' 12'' 30'' 15'' 1 2'' 15" 15'' 1 0'' 18'' 1 2'' 8 '' 456710 456750 2040 COMPREHENSIVE PLAN 1,800 0 1,800900 Feet ± Path: L:\2294\100\2040CompPlan\SE Proposed Trunk Sanitary Sewer.mxd Date: 2/1/2018 Time: 7:04:05 AM User: shujc0243 !Existing Gravity !Proposed Gravity !Proposed Gravity (Lateral)Existing ForcemainProposed ForcemainExisting MCES Forcemain(Interim Size Shown) #*MCES Lift Station !H Sewer Node (LS) = Lift StationSewer SubdistrictsMunicipal Boundary2040 MUSAParcel BoundariesStreamsLake/Open Water Map 7-3Proposed Trunk SanitarySewer System - SE District Draft Draft Copy -- 2/1/2018 109 To estimate average wastewater flows generated within the various sewer sub-districts, unit flow rates (in gallons per acre per day) are multiplied by the acreage for each land use category as identified in Appendix A. The unit flow rates for designing Corcoran’s trunk system are presented in Table 7-5. Wetland, right-of-way, and other undevelopable areas will not generate any sewer flow. The average wastewater flows for each sewer sub-district are presented in Appendix A. taBle 7-5: system design WasteWater unit floW rates Land Use Type Unit Flow Rate (Gallons/Acre/Day) Ag Preserve 0 Business Park 1,000 Commercial 1,000 Existing Residential 270 High Density Residential 2,000 Light Industrial 1,000 Low Density Residential 750 Medium Density Residential 1,050 Mixed Residential 1,200 Mixed Use 1,500 Parks/Open Space 0 Public/Semi-Public 250 Rural/Ag Residential 0 Undevelopable 0 The calculation of average wastewater flow rates for use in Corcoran’s trunk sanitary sewer design conservatively estimates wastewater generation at the municipal level so that no City trunk is undersized for its projected sewer sub-district. The values in Table 7-5 reflect conservative unit rate assumptions, particularly for commercial and industrial land uses, that allow Corcoran’s trunk system to accommodate higher wastewater-generating land uses such as manufacturing without being undersized. The conservative approach to estimating flows allows the City to remain flexible in planning future development by allowing for the possibility of localized development of higher-intensity use while also protecting against potential sewer backups. dEsign FloWs Corcoran’s trunk sanitary sewer system must be capable of conveying the anticipated peak wastewater flow rate (peak hour). The peak wastewater flow rate, or design flow, is calculated by multiplying the average flow rate by a variable peak flow multiplier, called the Peak Flow Factor (PFF). The PFF can generally be described as inversely proportional to the average flow rate (as the average wastewater flows increase, the applied PFF decreases). The PFF values applied in this study are shown in the following graphic as a curve and in tabular form. These values are generally conservative and widely used throughout the state for municipal sewer planning. The PFF values include a standard allowance for I/I, which is typical of new sanitary sewer construction as well as properly operating existing sewers. The first step in estimating Corcoran’s design flows involves designating each sewer sub-district to drain to a specific sewer node, generally the nearest down-gradient sewer node, within Corcoran’s proposed trunk sanitary sewer system. To calculate the design flows in the system, the total average flow to each sewer node is multiplied by the corresponding PFF. Calculation of design flows for Corcoran is summarized in Appendix A. Maps 7-2 through 7-4 identify the sewer sub-districts and sewer nodes included as part of the larger trunk sewer system. For the purposes of this narrative, a sewer node is identified within trunk sewer system at the following locations: • Upstream end of a trunk (generally considered 10” pipe and larger) sewer pipe • Trunk sewer junction points (nodes) • Trunk sewer pipe size changes • Lift stations For lift stations, a node is identified as a lift station when the entire wastewater flow reaching that lift station will pass through the lift station. However, there will also likely be a few isolated, small lift stations that are required to serve smaller portions of some sewer subdistricts, rather than attempting to deepen long lengths of trunk sewer to provide gravity service to such small areas. Locations for this type of small lift station are not identified on Maps 7-2 through 7-4 or in Appendix A. trunk sanitary sEWEr systEM sizing Corcoran’s trunk sanitary sewer system layout is identified on Maps 7-2 through 7-4. The pipe sizing for Corcoran’s trunk sewer system is based on several parameters including system design flows, trunk sewer length, and trunk sewer grade. Based on the trunk system layout on Maps 7-2 through 7-4, the trunk sewer length between sewer nodes is determined (the “straight-line” length is generally increased somewhat to allow for the longer, “meandering length” that will typically result from following the actual street locations). The trunk sewer grade is determined based on the minimum sewer depth at each sewer node necessary to provide service to the contributing sewer sub- district(s). The design flows calculated in Appendix A indicate the minimum conveyance capacity that must be provided in the trunk sanitary sewer system between 2 given sewer nodes. With all these design parameters in place, the trunk sewer pipe diameter between 2 sewer nodes is calculated. Corcoran’s trunk sanitary sewer system design calculations are presented in Appendix A. The system design presented in this Comprehensive Plan supersedes the trunk sanitary sewer system design information presented in Corcoran’s 2030 Comprehensive Plan. The wastewater flow projections in this Chapter, when combined with the sewer maps Maps 7-2 through 7-4 and design information contained in Appendix A, provide Metropolitan Council with Corcoran’s wastewater generation and trunk sewer design information as required in the 2040 WRPP. infiltration and infloW (i/i) The Metropolitan Council’s 2040 Water Resources Policy Plan (WRPP) states that the Metropolitan Council will establish I/I goals for all communities discharging wastewater to the MDS. As presented in the 2040 WRPP (Table A-2 thereof), I/I mitigation goals are determined by establishing the allowable peak flow rate, and are approximately equal to the previously-presented PFF values divided by 0.85. Communities that are identified as needing to eliminate excess I/I will be required to submit a work plan that details work activities to identify and eliminate sources of I/I. The Metropolitan Council can limit increases in service within those communities having excess I/I that do not demonstrate progress in reducing their excess I/I. The Metropolitan Council has not identified Corcoran as a community with observed excess I/I. PICTURE PLACEHOLDER Figure 7-1 Draft Copy -- 2/1/2018 110 With Corcoran now beginning to utilize connections to the MDS, a primary wastewater system goal of Corcoran and the Metropolitan Council is the limitation of clear water inflow into wastewater collection systems. Based on the guidance in the Metropolitan Council’s 2040 WRPP and the projected average wastewater flows in Table 7-3, Corcoran’s corresponding I/I goals are presented in Table 7-6. 1Projections include both system design flow and I/I flow components. The allowable peak hourly flow rate projections presented in Table 7-6 are not allotments and can be modified by Corcoran through its regular Comprehensive Plan Update or Comprehensive Plan Amendments. It should be noted that the peak flow rates provided in Appendix A do not represent actual metered peak flows and therefore should not be confused with the City’s I/I goal in Table 7-6. Metropolitan Council will determine compliance with the City’s I/I goal based on actual metered flow data at each connection to the MDS. To limit the amount of I/I into Corcoran’s future trunk sanitary sewer system, the City has enacted an ordinance prohibiting connections such as surface water and sump pump connections to the trunk sanitary sewer system. individual seWage treatment systems (ists) The majority of residences (approximately 2,000) are on ISTS in Corcoran. Hennepin County is the responsible authority for permitting and tracking the installation, operation, maintenance, and enforcement of all ISTS in Corcoran. Current Approach to ISTS: • ISTS are abandoned when the structure is connected to the MCES sewer system. • There are an estimated total of 2,000 ISTS in Corcoran which are shown on Map 7-5. The majority will remain placc, since they are outside the MUSA. • Corcoran’s role in managing ISTS for compliance involves cooperating with Hennepin County as the ISTS authority. Map 7-5: Unsewered Areas interCommunity floW ConneCtions The only intercommunity connection for Corcoran is in SE Corcoran, where a very small flow (0.02 mgd peak flow) from a few houses flows into Maple Grove (subdistrict SE-A). Corcoran currently has no other intercommunity flow connections to neighboring municipalities. CentraliZed WasteWater treatment systems Corcoran has a current ordinance regulating the siting, maintenance, and monitoring of centralized wastewater treatment systems. Section 940 of the Corcoran Code requires that proposed centralized wastewater treatment systems be compliant with MPCA standards, comply with all City requirements, and have no adverse impact on the environment or neighboring properties. Corcoran City Code also requires that a management plan identifying an annual schedule for maintenance, inspection, and monitoring of the centralized wastewater treatment system be provided to the City for approval. Currently, there is 1 centralized wastewater treatment system in Corcoran within the manufactured home park, Maple Hill Estates. This system is anticipated to be connected to the existing City sewer in 2018 (connection near node SE-24).

To support that commitment and meet the requirements of the Elm Creek Watershed Management Commission, the Metropolitan Council, Minnesota Statutes 103B.235 and Minnesota Rules 8410, Corcoran prepared a Local Surface Water Management Plan (Local Plan) to assess the current condition of its surface waters, identify existing or potential problems related to surface water management, and develop and implement solutions. The Local Plan must be included as a chapter in the Comprehensive Plan. The full Local Plan is in Appendix B. Chapter 8 Surface Water provides a summary of Cocoran’s local surface water management plan. goals and PoliCies Corcoran’s goals and policies for stormwater management are developed to reflect and support the City’s commitments to protecting surface water quality. These commitments are documented primarily in the City’s Stormwater Pollution Prevention Plan (SWPPP) and its Local Surface Water Management Plan (Local Plan), but they also reflect the goals and policies of the Elm Creek Watershed Commission (Commission) and those of other organizations and agencies that set laws, rules and standards or offer guidance regarding surface water protection and improvement. The Commission’s Third Generation Watershed Management Plan (WMP) identifies several goal areas and associated policies. Because the WMP guides much of the Local Plan content, and because the issues and goals identified in the WMP reflect similarly important issues in Corcoran, the City has developed policies within the same goal areas: • Water quantity • Water quality • Groundwater • Wetlands • Drainage Systems GOAL 1: Support the goals of the Commission to manage the quantity of stormwater runoff. Policy 1: As land is developed or redeveloped, abide by the Commission’s Rules and Standards regarding water quantity. Policy 2: As appropriate, remove or support removal of unattached deadfall in Rush Creek and its tributaries. Policy 3: Review ordinances and policies for consistency with Commission goals and policies for water quantity. These includes ordinances and policies related to shorelands and floodplains. GOAL 2: Corcoran recognizes the importance of maintaining and improving water quality in its lakes, wetlands, and streams. Policy 1: As land is developed or redeveloped, abide by the Commission’s Rules and Standards regarding water quality. Policy 2: Continue reviewing, updating and implementing components of the City’s Stormwater Pollution Prevention Plan (SWPPP). Policy 3: Participate in Municipal Separate Storm Sewer System (MS4) permit renewals and revise the City’s SWPPP as needed. Policy 4: Participate in the development and implementation of TMDL and WRAPS studies by attending meetings, providing feedback and helping identify projects that may offer water quality benefits. Policy 5: As feasible, support or assist the Commission or other agencies with water quality monitoring. Policy 6: As feasible, support studies that identify water quality problems and solutions. This includes but is not limited to Subwatershed Assessments. Policy 7: Work with the Commission and other organizations and agencies, as appropriate, to pursue grant funding and other funding to support the development and implementation of water quality improvement projects. Policy 8: As needed, review City ordinances and policies for consistency with Commission goals and policies for water quality. These include ordinances and/or policies regarding manure management. GOAL 3: Many of the City’s residents and business owners rely on individual wells for water supply, and this will likely continue for the foreseeable future. To support groundwater recharge and protection, the City adopts the following policies. Policy 1: As land is developed or redeveloped, abide by the Commission’s Rules and Standards regarding groundwater quality, particularly those requiring abstraction and/or infiltration of runoff. Policy 2: Participate in the Commission’s efforts to identify appropriate, cost-effective Best Management Practices regarding abstraction/ infiltration and groundwater recharge. Policy 3: Participate in the Commission’s efforts to educate the community about groundwater and its connection to stormwater runoff and surface water quality. GOAL 4: Corcoran recognizes the importance of protecting its many wetlands. Minnesota’s Wetland Conservation Act (WCA) established rules regarding wetland management, and it requires the appointment of a Local Government Unit (LGU) to administer them. In recognition and support of wetland management goals and requirements, Corcoran adopts the following policies. Policy 1: As land is developed or redeveloped, abide by wetland buffer standards and established by local ordinance, Commission Rules and Standards, and state law. Policy 2: As needed, review City ordinances and policies for consistency with Commission Rules and Standards and state law regarding wetland buffers. Policy 3: As needed, review and revise the LGU agreement. This may include developing or updating an LGU contract or assuming the LGU role. GOAL 5: In Corcoran, stormwater drainage is accomplished primarily through public and private ditches. County ditches have been under the authority of Hennepin County, but if requested, the Commission will review and reconsider the appointment of ditch authority. To support that goal, the City adopts the following policy. Policy: Participate in Commission review of ditch authority. GOAL 6: City operations and programs regarding stormwater management are documented primarily in its SWPPP and its Local Surface Water Management Plan (Local Plan), the latter reflecting many of the goals and policies of the Commission’s WMP, including its goals for operations and programming. In support of those goals, the City adopts the following policies. Policy 1: Participate in Technical Advisory Committee meetings and regular meetings of the Elm Creek Watershed Commission. Policy 2: Continue the City’s stormwater education program, concentrating on high-priority topics identified in its SWPPP. Accept educational assistance from the Commission as it becomes available. Policy 3: As feasible, support and assist the Commission’s monitoring program to assess water quality, water quantity, and biotic integrity and to evaluate progress in meeting TMDL goals. Policy 4: Participate in developing Commission Rules and Standards regarding stormwater management, and as needed, review and revise local ordinances and policies for consistency with the Commission. Policy 5: As needed, request technical or financial assistance, or both, from the Commission to support stormwater management or water quality improvement projects. SURFACE WATER PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 126 The City of Corcoran is situated almost entirely in theRush Creek and Elm Creek Watersheds, a drainage basins that also includes parts of Rogers, Dayton, Champlin, Maple Grove, Plymouth, and Medina (Map 8-1). As a member of the Elm Creek Watershed Management Commission (Commission) Corcoran and other cities manage the watershed’s surface water resources. Map 8-1: Watershed Management Organization and Drainage Patterns One of the duties of the Commission is to prepare Watershed Management Plans (WMPs) that set goals, policies, rules, and standards for surface water management. The most recent WMP, the Third Generation Watershed Management Plan, was approved in 2015. According to Minnesota law, Corcoran must prepare a Local Plan after a WMP is updated to ensure that the City’s approach to managing surface water resources is consistent with that of the Commission. This Local Plan satisfies that requirement. Other regulations also influence or dictate the City’s responsibilities regarding surface water management. They include the Municipal Separate Storm Sewer System (MS4) permit program, a federal and state initiative that requires the City to develop and implement a Stormwater Pollution Prevention Plan; the Minnesota Wetland Conservation Act; the Minnesota Buffer Law; and various Total Maximum Daily Load (TMDL) studies that aim to improve surface water quality by reducing the amount of pollution reaching our lakes, wetlands, and streams. Current Conditions An inventory of Corcoran’s land and water resources finds a mosaic of farms, businesses, homesteads, and residential developments in a historical setting of maple-basswood forest and wet prairie. Land use has changed significantly since the time before European settlement. Logging and farming began the transition, and the many drainage ditches and tiles in the City hint at the effort needed to convert characteristically wet soils into ones better suited for agriculture. Today Corcoran’s agricultural tradition remains strong, especially in the north and west parts of the City. Urban residential and commercial development is increasing from the east and south and is expected to continue. Urban services such as piped sewer and water already serve parts of southeast Corcoran and are anticipated for more of the region delineated by the Metropolitan Urban Service Area (MUSA). Development within the MUSA and elsewhere offers opportunities to install urban stormwater Best Management Practices (BMPs), such as catch basins and stormwater treatment ponds, to prevent pollutants from being carried by stormwater runoff to surface waters. Both urban and rural BMPs will be important to improve surface water quality in Corcoran. Much of the North Fork of Rush Creek and part of the South Fork have been designated as impaired by the Minnesota Pollution Control Agency (MPCA), meaning that water quality does not meet one or more state standards. The Elm Creek Watershed-wide TMDL Study and Watershed Restoration and Protection Strategy (WRAPS) identify measures that could correct the impairments. So do similar studies completed to correct impair- ments in the Pioneer-Sarah Creek Watershed, which includes a small area in southwest Corcoran. Applying the Commission’s strict rules for stormwater treatment as land is converted from agricultural to other uses is expected to yield benefits throughout the City. Additional projects are planned to reduce surface water pollution from targeted areas. Corcoran’s interest in preserving natural resources is not limited to its waters. Remnant native plant communities persist, and the City’s Parks and Trails Plan identifies search areas for greenway corridors and open spaces that co- incide with ecologically significant communities in upland and wetland areas. Such areas provide habitat for many species and help protect water quality by limiting impervious surfaces and maintaining vegetation that infiltrates stormwater runoff. ProBlems and solutions Some of the problems related to surface water management are described in the previous paragraphs. Additional issues and their possible solutions are identified in the WMP or by City staff, and all are discussed in the Local Plan. A summary of selected issues is given below. • Ordinance adoption and review: The City will adopt a manure management ordinance and will review its wetland and shoreland ordinances for consistency with watershed rules and other regula- tions. • Impaired waters projects: To help improve water quality in Rush Creek and elsewhere, the City will apply the Commission’s strict development standards, connect sanitary sewer at Maple Hill Es- tates to the MCES system, continue septic system education, and implement one or more recommendations from the Rush Creek Headwaters Subwatershed Assessment. • Operation, maintenance, and inspection of privately-owned stormwater BMPs: Among other measures, the City will continue inspecting BMPs in accordance with the City’s Stormwater Pollu- tion Prevention Plan. • Wetland improvements: The City will work with the Commission and other cities on potential wetland improvements north of the Ravinia development in Corcoran and south of the Laurel Creek development in Rogers. At the same time, the City will explore a possible stormwater pond retrofit in existing commericial and industrial areas in Corcoran. The City has prepared implementation and capital improvement plans that project expenses and possible funding sources through 2025. The Local Plan can be amended if needed to update these plans or other contents, with review by the Commission or the Metropolitan Council, if required.

Additionally, Minnesota Statute 103G.291 requires all public water suppliers within the metro area or that serve more than 1,000 people to have a Water Supply Plan approved by the Minnesota Department of Natural Resources (DNR). An approved Water Supply Plan is also a requirement to obtain a Water Appropriations Permit Amendment from the DNR. The City of Corcoran did not have a municipal water system at the time of the 2030 Comprehensive Plan Update, but with construction of new developments occurring since that time, Corcoran has initiated construction of its municipal water system. Water supply is currently provided via connection to the Maple Grove water supply system.A copy of the Corcoran Water Supply Plan is located in Appendix C. Use of this water supply is currently expected to continue through the current planning period, though Corcoran may eventually move towards developing its own municipal supply wells and treatment system, as discussed further herein. PoliCies and goals Corcoran is committed to developing a sustainable infrastructure system. A sustainable water supply meets the public demand and requires the responsible use of water now and in the future, without unacceptable social, economic, or environmental consequences. The City of Corcoran core principles include to: Goal 1: Construct the system including trunk and local collectors as development takes place withing the City. Policy 1: Require developers to construct a system in a size and manner to support future needs of the system. Policy 2: Extend the system to adjacent properties ad development takes place. Goal 2: Operate in an efficient and sanitary manner to protect public health, safety and welfare, to safeguard municipal finances, and to support development and economic vitality within the community. Policy 1: Implement preventative maintenance programs to protect and sustain the system. Policy 2: Restrict the installation and use of private water supply wells when necessary or appropriate. Water suPPly system The first housing development in the City of Corcoran to have municipal water and sewer services initiated construction in 2014 (Ravinia in south- east Corcoran). The water distribution system was extended from the Maple Grove water supply system (see Map 9-1) for the existing system layout. The downtown area of Corcoran was also recently connected, and discussions with other developers regarding other new developments in both southeast and northeast Corcoran are underway. However, given the very limited de- velopment that has occurred to date, historical water use data is not pre - sented herein. Other residents of Corcoran meet water demand through private water wells. As development continues in the City of Corcoran, expansion of the munic- ipal water system will occur in those portions of the city designated for municipal services. The City of Corcoran has developed their initial con- ceptual water system plan to guide the creation and expansion of a municipal water supply, storage, and distribution system for city residents. Map 9-1: Existing Water System WatEr dEMands Future water demands are determined based on served population projections and typical per capita water demand. Most of the City of Corcoran’s current (2016) population of 5,498 meets water demands through private wells and therefore limited existing municipal water demand exists. As new development occurs going forward, municipal water demand will increase proportionally. It is assumed the portion of sewered households would directly relate to the portion of the population served by the future municipal water system. To determine future water demand, typical total per capita water use in the metro area is applied to the projected served population. The average day total per capita demand used is 150 gallons per capita day (gpcd), which is similar to the observed water demand in Maple Grove. It is ijmportant to note, the total per capita water demand includes water uses for residential, commercial, public, and industrial water demands. A maximum day total per capita demand of 450 gpcd is used to determine the size of the conceptual water system, reflecting a peaking factor of 3 for the ratio of peak day demand to average day demand. The Metropolitan Council projects the number of people per household to gradually fall going forward, going from 2.68 people per household in 2020 to 2.40 people per household in 2040. Using a typical value of 2.5 people per household, the peak day water demand is 1,125 gallons per day per household. Using the Metropolitan Council’s projected sewered populations, which are assumed to equal the municipal water populations, the projected water demands are presented in Table 9-1. taBle 9-1: City of CorCoran PoPulation and Water demand ProjeCtions Year Total Population Served Population* Average Day Demand Maximum Day Demand Annual Demand 2010 5,379 0 --- 2020 6,700 1,300 0.20 MGD 0.59 MGD 73 MGY 2030 8,900 2,600 0.39 MGD 1.17 MGD 142 MGY 2040 11,300 3,320 0.50 MGD 1.49 MGD 182 MGY *Served population calculated from Metropolitan Council served households projections. City of Corcoran water demand calculated based on an average day total per capita demand of 150 gpcd and maximum day total per capita demand of 450 gpcd (3.0 peaking factor). As discussed in Chapter 7, the Metropolitan Council has projected southwest Corcoran’s municipal services population to be still near zero in 2040, but just beginning to develop. The 2040 water demand is projected to be almost entirely from northeast and southeest Corcoran. The Metropolitan Council’s forecasts do not differentiate between these 2 areas, but using a similar City- anticipated split as presented in Chapter 7, the 2040 demand of 0.50 MGD will be approximately 0.40 MGD from southeast Corcoran and 0.10 MGD from northeast Corcoran. The Maple Grove water distribution model provided to Corcoran indicates that average day demands of approximately 2.5 MGD have been planned for at each of the 2 primary Maple Grove connection points (i.e., one that is currently supplying southeast Corcoran near County Road 10 and one future connection for the northeast near County Road 30), well above the 2040 projected demands.

The conceptual water system must consist of water supply to meet maximum day demands, water storage to meet peak hour demands and emergency storage needs, and a network of trunk and lateral water mains to deliver the water. Throughout the current planning period, the water supply is anticipated to be obtained from Maple Grove for northeast and southeast Corcoran. Initially, southwest Corcoran would most likely be supplied via a joint water system with the City of Medina. Conceptual water tower locations are shown on Map 9-2, but the exact location, timing and sizing of water towers will be dependent on future development locations and timing. Given that early water system operation essentially utilizes existing storage in Maple Grove, and given that adequate initial water supply pressures exist, no water towers are immediately needed in Corcoran at the very start of development activity. Given that development has been initiated in southeast Corcoran, more detailed water distribution model development has been conducted for this area, including the sizing and timing of the first water tower. The need for the first water tower in southeast Corcoran was determined to be at a peak day demand of approximately 1.75 MGD, which is anticipated to be a 1 MG tower near the downtown area. At projected demand growth, this tower does not appear to be needed until some point beyond the current planning period. At the same time this water tower is constructed, a booster station is anticipated to be constructed at the supply entrance point near County Road 10, unless Maple Grove has elected to install its own booster station for the adjacent Maple Grove area, which would likely provide the needed pressure boost in Corcoran. At a conceptual level, the preliminary sizing of the water towers shown on Map 9-2 are as indicated in Table 9-2, noting that this reflects a more fully- developed condition in the service area shown (not 2040).

This is not anticipated within the current planning period, and will require installation of Corcoran’s own water supply wells and water treatment system(s). For example, to provide a water supply for the 2040 served population, the City of Corcoran will need to supply 1,050 gpm, which would potentially require 4 groundwater wells (using an assumed capacity of 400 gpm per well and assuming one standby well). Additional information on well capacity potential is included later in this chapter. The conceptual network of trunk water mains that will be needed to serve city growth is shown on Map 9-2, including potential locations for supply connections to neighboring communities. If, in the future, the City of Corcoran is able to supply water demand from its own municipal wells, the supply interconnections will then be maintained as emergency interconnections. The sizes of the trunk water mains shown on Map 9-2 will generally be 12-inch; however, some segments may be increased or decreased based on future design and distribution system modeling efforts. The estimated capacity of groundwater wells in the City of Corcoran needs to be verified through geological studies. When the city gets closer to the point at which municipal wells are desired, the city will conduct a well exploration program to identify capacity and location of future wells. Future groundwater wells will require disinfection and fluoridation, and groundwater testing will also be conducted to determine if additional water treatment is needed. As the municipal water system develops, decisions will be made that reflect the core principles, sound engineering, and fiscal reasonability to serve the residents of the City of Corcoran. resourCe sustainaBility The City of Corcoran is committed to a sustainable water supply meeting the public demand without unacceptable social, economic, or environmental consequences. Any future municipal groundwater wells will contain continuous monitoring of groundwater levels to allow the city to investigate well interference and potential natural resource impacts. The following sections detail potential natural resource impacts, groundwater sustainability, and source water protection. natural rEsourcE iMPacts In the current planning period, when Corcoran’s water supply system will rely on interconnection with the City of Maple Grove, additional pumping demands will be placed on the municipal wells in Maple Grove that could further increase impacts to natural resources within that community. Therefore, Maple Grove should consider any possible impacts of this increased pumping when updating their water supply plans. Relative to any future Corcoran municipal well installation, the 2015 Met Council System Statement identified very few surface water features that have interaction with the regional groundwater system. Only Jubert Lake and some areas of wetlands in northern Corcoran are indicated as receiving and discharging groundwater. A few scattered stream segments are also indicated as being supported by upwelling of groundwater. Future municipal well installation will need to consider the potential for any significant impacts to surface water bodies or water table aquifers. The 2015 System Statement identified one DNR groundwater level observation well just outside the northwestern corner of Corcoran. This well is indicated as having no trend in annual minimum groundwater levels (i.e., it is not trending up or down). sustainaBility Initially, it is planned or contracted that Corcoran will receive water through its interconnections with Maple Grove. At some point in the future, Corcoran expects to develop their own municipal water supply wells to supplement projected future demands. Any future municipal water supply wells for the City of Corcoran would likely utilize the Franconia-Ironton-Galesville (FIG) aquifer as the primary source of water supply. Since the FIG aquifer can be highly variable in the Twin Cities area regarding sustainability factors of recharge, storage, transmissivity, and specific capacity, an accurate estimate of overall sustainability cannot be determined until the city studies the potential yield of this aquifer in greater detail. Yields from the FIG aquifer can typically range between 200 – 1,000 gpm in the northern metro area. In addition to the FIG aquifer, it is also possible, but unlikely, the overlying drift aquifer may be utilized for large capacity water supply wells, if a sufficient thickness of coarse-grained, saturated sediments are located during a well siting study. Excellent drift aquifer deposits can produce yields greater than 1,000 gpm per well, when present. However, drift deposits tend to vary greatly over short distances, so the extent of good deposits can sometimes be limited to a small area. Underlying the FIG aquifer is the Mt. Simon sandstone aquifer, which is generally capable of supplying wells with yields ranging from 500 – 1,000 gpm. However, since recharge to this aquifer is somewhat limited and over- pumping the aquifer can create an unsustainable condition where water levels do not stabilize over time, the DNR has greatly limited the number of new high-capacity Mt. Simon wells in the 7-county metro area. It is unlikely Corcoran would be allowed to develop their municipal wells in the Mt. Simon aquifer unless it can be demonstrated that all other viable options for water supply have been exhausted. Further study will be required to better quantify the availability of groundwater for future municipal water supply wells. Studies will likely be a combination of investigation of existing well logs and geologic data in the area, along with a program of test drilling and test pumping at the sites thought to be most suitable for well exploration. PICTURE PLACEHOLDER Draft Copy -- 2/1/2018 133 Finally, since many existing homes in Corcoran are served by private wells, the drilling and pumping of high capacity municipal wells introduces the remote chance of possible interference between wells. While it is expected that some of the area private wells will be abandoned and existing homes connected to the municipal water supply system, a number of private wells can also be expected to remain in the area as development occurs. Since private wells utilize shallow ground water, drawdown impacts from future municipal wells are likely. As potential yields and sustainability of the drift and FIG aquifer are examined in future years, potential impacts to private wells will need to be studied more closely. Any pumping tests in these aquifers should include measurement of water levels in nearby private wells, if possible, to quantify the impacts of well interference. sourcE WatEr ProtEction Plan Since Corcoran does not currently have municipal water supply wells, the city has not yet been required to complete a wellhead protection plan. Maple Grove has developed a plan, which covers Corcoran’s water supply. Only after Corcoran drills their own municipal water supply wells will the city will be required to develop their own wellhead protection plan. Generally, the city will have a minimum of 2 years from the date a new well goes online to complete the associated wellhead protection plan. The plan must then be updated a minimum of every ten years or whenever a new well is added to the water supply system, whichever comes first. Assuming no sources of surface water will be utilized as a municipal drinking water resource, no surface water protection plan will be required for the City of Corcoran. Water Conservation Plan The City of Corcoran understands conserving water can be a cost-effective way to reduce the need to construct and operate additional water supply facilities. The City will explore water conservation programs to reduce demand for water, improve the efficiency in use and reduce loss and waste of water. Water conservations goals for the City will include the following: • Reduce unaccounted water use. • Monitor residential and total per capita water use as development continues. • Reduce peak water demands. The city will develop a water conservation plan to detail each of the conservation goals and how the water system compares to “benchmark” metrics for each of the goals. Potential conservation programs the city will review include: • Metering all water usage and implementing meter testing. • Conduct water audits to calculate unaccounted for water use. • Establish conservation oriented water rates for City customers. • Regulation and enforcement of federal, state, and local water regulations. • Supply educational materials through various means to inform City residents. • Conduct regular reviews of the effectiveness of developed conservation programs.

The concept of resiliency in the City of Corcoran is described here as it relates to a number of areas where the City can and should be prepared to respond to these changes. Resiliency is another way to describe a healthy community that can respond to inevitable changes. Our resilient design principles* include: 1. Diversity: Diversity of systems reduces the potential negative impact to the whole City of the failure of any one particular system. Increasing the diversity of systems means that we will want to maximize the diversity of different business types, institutions, sources of food, and industries, etc. 2. Redundancy: An increased redundancy of key infrastructure systems—including electrical power, fuel supply, waste water processing, food, and potable water supply - means that if one system is compromised, there is enough redundancy in the overall system to fill in for the compromised system until it can be replaced or repaired. 3. Modularity and Independence of System Components: Resilience capacity will be increased when system components have enough independence that damage or failure of one part or component of a system is designed to have a low probability of inducing failure of other similar or related components in the system. 4. Capacity for Adaptation: Resilience capacity will be increased by the relative adaptability of the various systems that comprise a City. City systems and infrastructure that are designed to quickly adapt to changing conditions and requirements will increase the overall resilience capacity of a City. The emergency management plan for the City will be evaluated to ensure capacity of the City system. 5. Environmental Responsiveness and Integration: The resilience capacity of a city is increased by how responsive and integrated its systems and functions are with its natural systems, services and resources. Environmental responsiveness and integration will not only reduce the cost of creating and maintaining technical infrastructure, but reduce the relative probability of infrastructure suffering significant negative impacts from events. *Adapted from ResilientCity.org goals and PoliCies Goal 1: Explore additional opportunities to incentivize high quality stormwater management at a site scale and City scale. Policy 1: Consider design standards for high quality stormwater amenities. Policy 2: Consider strategies to encourage water reuse. Policy 3: Consider strategies to reduce the use of potable water for irrigation. Goal 2: Preserve floodplain areas for flood mitigation and water quality. Policy 1: Continue to limit development in floodplain and shoreland zones through the adopted Floodplain and Shoreland Overlay Districts. Policy 2: Continue to work with Elm Creek Watershed Management Commission to establish and enforce water quality standards. Goal 3: Build, strengthen and encourage economic, social, and environmental systems that reinforce and amplify rural attributes. Policy 1: Support practices that foster local food gardening practices and a local food gardening culture. Policy 2: Support development patterns that preserve agricultural land. Encourage landowners to reenroll in agricultural conservation and preservation programs in the non-MUSA area. Policy 3: Consider allowing small-scale rural tourism opportunities. Policy 4: Consider a dark skies lighting policy for Corcoran. Goal 4: Intensify the rural landscape with rich, diverse landscaping that supports pollinator species. Policy 1: Encourage plant diversity and pollinator-friendly landscapes on private and public land. Policy 2: Review lawn maintenance and open space ordinances to ensure that pollinator friendly landscapes are not prohibited or overly restricted. Policy 3: Consider adoption of City practices that reduce or eliminate the use of systemic pesticides on public owned and managed land. Goal 5: Develop land use policies that encourage preservation of agricultural activities and create developments that reflect the City’s agricultural roots. Policy 1: Encourage enrollment of land in the Rural/Ag Residential areas in the Metropolitan Agricultural Preserves Program. Policy 2: Consider ordinances that create meaningful open spaces in both rural and urban areas of the City. Goal 6: Explore controlled/planned development of solar energy production as an alternative method to agriculture to preserve open space and lower density development. Policy: Continue to allow solar energy production as an accessory use. Stormwater stormWater Clean water and a clean environment are essential to a healthy community and a healthy life. As stormwater flows over the landscape the moving water can pick up sediment, bacteria, nutrients, pathogens, chemicals, phosphorus, nitrogen and other pollutants. It can carry these pollutants into nearby watercourses like creeks, drains, culverts, rivers, and lakes. Careful stormwater management can reduce erosion, prevent loss of land, and keep sediment and pollutants out of water. Building a resilient stormwater system is as simple as recognizing that there are many opportunities to clean, reuse, or preserve water as it interacts with the built and unbuilt landscape. Intervening at many points in the water cycle creates resiliency because if one system temporarily fails, others are still in place to mitigate disaster scenarios. One example of resiliency in stormwater management is the City of Corcoran’s robust effort to identify and preserve natural resources, such as wetlands and critical green corridors. As described further in Chapter 8 of this document, these natural systems are a critical partner to engineered systems. The City of Corcoran also encourages development projects that preserve and reuse water on site so that new developments don’t impact and overtax existing or neighboring infrastructure. Stormwater management is also guided to be multipurpose, focusing on both water quality and the quality of experience that waterbodies offer City and rural landscapes. People are drawn to water and like to live, recreate, shop, and relax near attractive, clean water features. Creating stormwater management systems that also function as public amenities provides economic benefits for a City that far outweigh any up-front costs. Insert sidebar with images similar to those on page 11 of the Southeast Design Guidelines shoreland and floodPlain management Shorelands and floodplains are low lying areas of land around waterbodies that take on excess water during period of high rainfall and flooding events. Floodplains, as an ecosystem, also provide a number of valuable ecosystem services such as improving water quality, providing habitat for wildlife, and groundwater recharge. Best practices for shorelands and floodplains include requiring natural buffers adjacent to these areas, limiting development and partnering land use with other compatible land and resource management uses such as conservation easements, parks and trails and some agricultural uses. The City of Corcoran has existing ordinances – in Sections 1050.020 and 1050.030 of the Zoning Ordinance – that limit development in floodplain areas and within a certain distance of waterbodies. The City will continue to enforce these regulations to protect these resources. RESILIENCE Draft Copy -- 2/1/2018 142 rural resilienCy Corcoran’s rural character is beloved by long-time residents and is identified as a draw for newer residents. Two surveys conducted in 2017 as part of the Comprehensive Plan update confirmed residents’ desire to preserve the rural character and land that is used for active agricultural production. At the same time, because of its’ close proximity to the Twin Cities (and associated land-use and economic pressures) the City continues a slow evolution from a rural agricultural landscape to a more developed suburban edge of the metropolitan area. In addition to production agriculture, rural services such as land management, water storage, nature management, alternative energy production, and rural-tourism can strengthen rural networks because they require natural resources and open space. The visual aesthetic of the City of Corcoran is also a powerful tool for preserving and communicating the rural character. Plant species diversity should be encouraged in open space, residential and commercial landscaping, and on privately or publicly owned land. The sum of individual efforts can create a powerful impact and heighten the sense of rural character. In addition to planting for diversity, planting pollinator-friendly landscapes will be important in Corcoran to provide critical habitat for the wildlife that contribute enormous value to landscape health and agricultural systems. The City of Corcoran has many tools and strategies already in place to protect its natural resources. Building rural resiliency will depend on the continued effort and support of these tools. An example of one of these tools is the Natural Resource Inventory that identified significant natural resource areas in the community and provided recommendations for the preservation and enhancement of these natural systems. Another is the Open Space and Preservation Plan in Corcoran’s Subdivision Ordinance. Open Space and Preservation (OS&P) Plats aim to preserve natural resources, natural habitat, and vegetated corridors. Incentives for land owners to protect these landscapes helps preserve natural landscapes and viable tracts of land for long-term agricultural use. agricultural PrEsErvEs The City of Corcoran encourages the continuation of agricultural use within the community. This policy expresses the City’s endorsement of the Metropolitan Agricultural Preserves program. All land parcels in the Rural/ Ag Residential land use designation that meet the requirements for eligibility in the Metropolitan Agricultural Preserves program according to MN Statute §473H may apply to the City for enrollment. This policy is not intended to interfere with agricultural status of any lands prior to adoption of the Comprehensive Plan. solar aCCess ProteCtion The Metropolitan Land Planning Act (MN Statute §473.859, Subd. 2) requires that local comprehensive plans include an element encouraging the protection and development of access to direct sunlight for solar energy systems. The City of Corcoran will protect such access by requiring minimum standards for lot sizes, amounts of open space, yard setbacks, and maximum height of buildings for urban residents that create the opportunity for all building owners to develop solar energy facilities if desired. The City’s zoning or other regulations have been written to ensure that solar energy systems are an allowable component of any building construction in the City. In 2016 the City of Corcoran passed a solar ordinance amendment and approved 2 community solar gardens. The council has since modified the ordinance to prohibit new community solar gardens, but continues to allow solar energy production as an accessory use. As development continues to edge into Corcoran’s more rural settings, solar energy production may become a viable way to retain lower densities and open space, and create policy that incentivizes or allows this land use.
