The typical process is as developments are proposed and move towards construction, the trunk system is reviewed and revised as necessary to facilitate current and future development. Maps are attached for your review. 1.0 Sewer SE District-- The developments of Lennar, Downtown, and currently Bass Lake Crossings are served by the main trunk system installed in 2012 and 2014. MCES will construct the regional Lift Station in 2018 thereby completing the permanent wastewater system for the SE District. The SE trunk system was modified to construct a “temporary” Lift Station along CR 10 to service Downtown connections, and the developable acreage south of CR 50. NE District – MCES has constructed the permanent connection near the “four corners” of Maple Grove, Dayton, Rogers and Corcoran along CSAH 101 which has generated interest in extending sewer south towards CR 30. SW District – This area of Corcoran remains rural, with the recent Park Place expansion utilizing on site water supply and fire protection and septic. A future connection to Medina may be changed towards Maple Plain sewershed, since MCES will connect to Loretto by 2020. The MCES cost is significant for Corcoran, a summary is given in the Attachments. Funding for the trunk system is via Trunk Line Area Charge, and is adjusted to represent recent construction costs and remaining buildout needs. Each District will have an individual TLAC, and should the NE District move forward this charge will be established to convey to developers. 2 C:\Users\TorKC0063\Documents\Corcoran Offsite\3_City Projects\1A_Comp Plan Items\Transportation\Utility Workshop Cover Memo.docx 2.0 Water SE District—The water system has made significant progress with service from Maple Grove to Lennar and Downtown. A significant benchmark for the SE District will be to “loop” along CR 116, which greatly increases fire flow and provides redundancy for maintenance. Water pressure modeling was performed in 2016 and fire flow / storage analysis reviewed to estimate the timing for the first water tower. Moving forward the model will be updated with actual usage from billing records, however it appears the SE District will construct storage at around 1,500 homes or the equivalent residential/commercial blended land use. NE District— A second connection to Maple Grove will occur near CR 30 for the NE District. Long term, the SE District will also connect to NE, and allow the sharing of storage and provide redundancy with the Maple Grove system. SW District -- Water to supply the SW District may involve a joint powers system with Medina for development near HWY 55 and CR 19. If this is a a Corcoran only system, or joint powers is not possible at the time sewer is available, it is possible for development to move forward with individual wells and fire suppression storage for each property. 3.0 Transportation The 2030 Transportation Plan is attached for review. An update on the realignment in the CR 10 / Larkin alignment will be discussed at the Workshop. 3 C:\Users\TorKC0063\Documents\Corcoran Offsite\3_City Projects\1A_Comp Plan
