The Commission asked Lennar’s representative, Paul Tabone, the reason for offering the smaller homes. Mr. Tabone stated that the market has changed over the 6 years since the preliminary PUD was approved and that the more affordable homes were more in demand. He also stated that due to the ponding requirements and other factors, the lots had to be adjusted; however, the actual net gain with the smaller lots was one lot. The Commission discussed what would be appropriate to be allowed for the Discovery series (garage-forward design), but could not come to a consensus on the allowable protrusion dimensions. 5a.

TO: Corcoran Planning Commission FROM: Kevin Shay through Kendra Lindahl, Landform DATE: April 24, 2019 for the May 2, 2019 Planning Commission Meeting RE: Final PUD Development Plan and Final Plat for U.S. Home Corporation (dba Lennar) for Ravinia 11th Addition (City File 19-005) 60-Day Review Deadline: May 31, 2019 1. Application Request Lennar submitted a request for approval of a final plat and final PUD development plan “Ravinia 11th Addition” to allow 14 single-family detached home lots and four outlots. This is modified from the 15- lot subdivision that the City reviewed in February. The proposal showing 15 lots encroached on the access easement that was originally created to allow access to the Schnell property at 19210 Hackamore Road. The access easement is unimproved as the Schnell property has a driveway from Hackamore Road. No agreement could be obtained between the properties to vacate the easement and the loss of a lot with this plan is to keep the access easement free of improvements. Only the final PUD development plan is reviewed by the Planning Commission. The Planning Commission recommendation will be forwarded to the City Council. The City Council is expected to take action on the final PUD development plan and final plat on May 23rd. 2. Context Level of City Discretion in Decision-Making The City’s discretion in approving a final PUD development plan is limited to whether the proposed plan is in substantial conformance with the approved preliminary PUD development plan. If it meets these standards, the City must approve the final PUD development plan. The City’s discretion in approving a final plat is limited to whether the proposed plat meets the standards outlined in the City’s subdivision and zoning ordinance and the conditions of preliminary plat approval. If it meets these standards, the City must approve the final plat. Background The City Council approved the Ravinia rezoning to PUD (Planned Unit Development), Preliminary PUD Development Plan and Preliminary Plat on December 23, 2013. Agenda Item: 6.a. Lennar Final PUD Development Plan – Ravinia 11th Addition (19-005) 2 May 2, 2019 The Final PUD Development Plan and Final Plat for Phase I was approved by City Council on April 24, 2014. There have been ten phases of Ravinia granted final approval and several PUD amendments since the 2014 approval. The homeowners submitted a sketch plan for this property in November of 2016, which received Council feedback and general support. The Planning Commission and City Council reviewed the Lennar request for Preliminary Plat, Rezoning to PUD and Preliminary PUD Development Plan at their meetings on February 7, 2019 and February 28, 2019. 3. Analysis of Request Staff has reviewed the application for consistency with the approved preliminary plans, as well as City policies. The City Engineer’s comments are incorporated into this staff report and resolution and the detailed comments are included in the attached engineering memo dated April 19, 2019. Staff has included a condition that the applicant must comply with the memo. Final PUD Development Plan Architecture The applicant submitted a series of house plans and color palettes for the project with the preliminary PUD development plan. Both the 55- and 65-foot wide lots with the 2-car and 3-car Discovery home products are proposed to be built in this phase. The City will review each house plan to ensure that the homes are compatible with the standards in the original approvals for both design and materials. As part of the original Ravinia submittal, Lennar asked for flexibility to allow the face of the garage to exceed the 55% limit for the building face. Lennar indicated in their narrative that to offset the larger garage, the garage would remain flush with the home. Staff believes this was an important component of the PUD by providing this higher quality architecture. While reviewing the 12th Addition, staff and Planning Commission recommended that the home models be limited to those where the garage is located at or behind the front elevation of the home. The Council will review this item at their April 25th meeting and is expected to take action. Staff recommends that those conditions for homes in the 12th Addition related to garage protrusion apply to the 11th Addition as well. Staff will provide an update on the Council action related to the 3-car Discovery units at the Planning Commission meeting. Streets These streets have a 50-foot right-of-way and will be required to be stubbed to the south property line so that they can be extended to the adjacent properties in the future. This is consistent with City Engineering standards for residential streets. Parking will be allowed on one side of these local Lennar Final PUD Development Plan – Ravinia 11th Addition (19-005) 3 May 2, 2019 streets. Larkspur Lane (the western street) will have a temporary cul-de-sac for public safety and public works turnarounds, with Road 2 utilizing a temporary turnaround. The lot/outlot with turnarounds are unbuildable, as the buildable area is used for these turnarounds. The temporary turnarounds will be removed if the easement is vacated, the property to the south is developed and the streets are extended. At that time Lot 1, Block 3 would be buildable and Outlot C will remain unbuildable. This is consistent with the preliminary approvals. Street Lights The applicant has not submitted street lighting details. Staff recommends that the street lighting approved for previous Ravinia phases be provided in this development. This is consistent with Section 945.020, Subd. 17, which requires ornamental poles. A uniform style of light fixture should be used throughout the site and the applicant will be required to indicate which style will be used in their final development plan application. Driveway Locations Driveway locations are not indicated on the plans submitted. As a condition of approval, the City requests revised plans that demonstrate the location of all proposed driveways for this phase of development. Staff will review the driveway location to ensure that there are no conflicts with planned infrastructure and landscaping. Staff will also review the plans to ensure that there is a minimum of 22 feet between the garage and the right-of-way. Sidewalks and Trails The plans show sidewalks on one side of the street as required. The Comprehensive Plan shows an on-road trail on County Road 101. This trail will be built when County Road 101 is improved, but the applicant must show how the trail can be accommodated, prior to release of the final plat. Hennepin County has requested an additional 5-foot trail easement to be dedicated on the west side of County Road 101. This is consistent with the previous phases of Ravinia. Setbacks The previous phases have approved the following dimensional requirements for the 55- and 65-foot wide lots: 55-foot lots 65-foot lots Front, From County Road 101* 100 feet 100 feet Front, From all other streets 20 feet 20 feet Front Porch (≤ 120 square feet) 15 feet 15 feet Side 5 feet 5 feet Rear 25 feet 25 feet Maximum Principal Building Height 35 feet 35 feet Lennar Final PUD Development Plan – Ravinia 11th Addition (19-005) 4 May 2, 2019 Landscaping The applicant’s plans show 42 trees where 14 are required for the residential lots. Half of the trees are planted at the edge of the front drainage and utility easement and are evenly spaced along the residential street to create an attractive streetscape with a mix of Princeton Elm and Autumn Blaze Maple. The remaining 21 trees are planted in the rear yard of Lots 5 and 6 adjacent to County Road 101 to provide screening from the county road. The screening contains a mix of Prairie Rose Crab, Colorado Green Spruce and White Pine. As a condition for approval, no certificate of occupancy will be issued for home that does not have street trees planted as shown on the landscape plan submitted to the city. Mail Delivery One centralized mailbox location should be shown on the landscape plans. The location of mailboxes must be approved by the US Postal Service. The applicant will need to provide proof of the approved location to the City. Park Dedication A cash in lieu of land fee has been calculated based on the per capita share of park system costs at $3,970 per single family unit (14 x $3,970 = $55,580 based on the current fee schedule). Final Plat The applicant is requesting approval of a final plat to create 14 lots and four outlots. The final plat will need to be revised to plat the right of way to the edge of the plat, along with extending some lots to contain the Tabor driveway easement. • The final plat is reviewed only by the City Council. The development contract will also be reviewed by the City Council. The Planning Commission will not provide a recommendation on the Final Plat. If this subdivision is approved, it would bring the total number of platted lots to 361 of 480 approved: • Phase 1 = 38 Units • Phase 2 = 36 units • Phase 3 = 27 units • Phase 4 = 44 units • Phase 5 = 47 units • Phase 6 = 23 units • Phase 7 = 37 units • Phase 8 = 20 units* • Phase 9 = 49 units • Phase 10 = 26 units • Phase 11 = 14 units** Total Units = 361 units (75% of the approved lots) Lennar Final PUD Development Plan – Ravinia 11th Addition (19-005) 5 May 2, 2019 *The Ravinia 8th Addition added land and units to the Ravinia project and the total increased from 446 to 466 units and 268.07 gross acres to 274.07 gross acres. **The Ravinia 11th Addition added land and units to the Ravinia project and the total increased from 466 to 480 units and 274.07 gross acres to 279.68 gross acres.

Ravinia 11th Addition lot tabulation 3) Wenck (city consultant) Ravinia 11th Addition review dated January 28, 2019 with redline response 4) Geotechnical Evaluation Report for Nichols Property dated January 7, 2019. 5) Nichols Stormwater Management Plan, by Advanced Engineering and Environmental Services dated March 15, 2019. 6) Ravinia overall density and phasing plan. Findings; 1) A complete application was received on April 10, 2019. The initial decision period, per MN Statute 15.99 expires on June 9, 2019. 2) This site is in the Elm Creek watershed basin. It drains south and east under CR 47 and through a series of wetlands and floodplains before reaching Elm Creek in Plymouth, just east of Peony Lane. 3) The existing land use is a rural, single family residential lot. It has 0.53 acres of impervious surfaces and 5.06 acres of grass/woods/wetland/ponding areas. 4) The proposed land use will have 1.65 acres on new impervious surfaces (note, this includes 0.31 acres from future development to the south that will be treated in filter basin 21) and 4.06 acres of lawns/grass/woods/wetlands/ponding area. Stormwater Management 5) One onsite filter basin is proposed in this addition. 6) There are three existing wetlands on this site that will not be impacted by this development. a. Wetland 16 is along the west side of the development. A 21” pipe will route water from wetland 16 east into wetland 17. b. Wetland 17 is on the south side of this development and drains to the south off site. c. Wetland 15 is on the east side of the site and drains into an existing ditch/culvert on CR 110 that runs east into the Fieldstone development in Maple Grove. i. The filter basin will drain into Wetland 15. 7) There are two discharge points from this development. a. Water flowing into wetland #17 then south off site b. Water flowing into Wetland #15 then into the CR 101 ditch culvert system. 8) Wetlands and filter basins will have drainage and utility easements placed over them as part of the platting process 9) The City of Corcoran requires landowners maintain stormwater basins. Lennar will be forming a Homeowners Association to operate and maintain this onsite filter basin. a. An operation and maintenance agreement between the city and HOA must be approved and recorded on the land title. 10) When the area south of this development is platted, it is presumed that Road 2 in the 11th addition will terminate into a cul-de-sac with five additional lots on that property. The stormwater filter basin on the 11th addition is proposed to treat this future development for rate, quantity and quality controls. 11) Rate controls will meet the Commission standards for 2, 10- and 100-year discharges. Based on the 2 main discharge points on this site, the rates will be as follows; 2-yr (cfs) 10-yr (cfs) 100-yr (cfs) Pre-Development Rates South (into Wetland 17) 6.3 13.1 22.5 Post-Development Rates South (into Wetland 17) 5.4 11.0 19.3 Pre-Development Rates East (into CR 101 ditch) 10.1 20.0 29.6 Post-Development Rates East (into CR 101 ditch) 7.6 19.6 28.3 12) Abstraction requirements will be for 1.65 acres new impervious areas on site and 0.31 acres of proposed new impervious areas for the future development to the south that will drain into the new filter basin in Ravinia 11th Addition. Total filtered abstraction required in this basin will be 1.96 new impervious areas, or 7,826 cubic feet. Actual filtration volume proposed will be 9,675 cubic feet, which will meet our abstraction requirements. a. Drawdown on the filter basin will be 23.7 hours. b. A forebay will be constructed as part of this basin. Its size was based on 10% of the filtration volume, or 976 cubic feet. 13) Phosphorus and Total Suspended solids were analyzed using P8 for pre and post development. Both loads will be reduced after development vs pre-development. This will meet the Commission standard. Water quality and abstraction will be as follows; Condition (based on 5.67 acres) TP Load (lbs/yr) TSS Load (lbs/yr) Abstraction (cu. ft.) Filtration (cu. ft.) Annual Volume* (ac. ft.) Pre-development (baseline) 2.3 733 N/A N/A 4.04 Post-development without BMPs 5.0 1547 7826 Post-development with BMPs 1.9 151 9675 4.65 Net Change -0.4 -582 N/A -1797 N/A 14) Buffer widths on the wetlands do not appear to meet the Commission standard of 10’ minimum, 25’ average. 15) The City of Corcoran is the LGU in charge of administering the MN WCA. There does not appear to be any impacts to the wetlands in this parcel. 16) Grading and erosion control plans meet the Commission’s requirements. Recommendation: An operation and maintenance agreement between the city and HOA must be approved and recorded on the land title. Wetland Buffers must meet the ECWMC requirements.
