Date: 04/22/04 Prepared by: Mark.Maloney Item: D-2 Other Business ..Item Description: Snail Lake Landing Development Snail. Lake Landing is a proposed 52-parcel. single-family residential subdivision located on the Mounds View School District property in Shoreview, south of Snail Lake Boulevard and west of Mackubin Street. This proposed development is can ently being considered by Shoreview's Planning Commission and is likely going to be presented to the City Council. sometime. in May. The original grading plan submitted to the City has been attached for reference. Mounds View School District recently declared the land as surplus property and sought out a developer to develop he property. The School District has. formed a partnership with Snail Lake Landing, LLC to develop. this property with single-family residential uses. The site sits atop a hill where drainage currently breaks toward two distinct drainage sub-basins; to the north toward Snail Lake, and to the southeast toward Suzanne Pond, which is hydrologically connected to Grass Lake. The storm water management plan originally proposed by the developer followed the natural drainage of the site by managing runoff and water quality through a series of storm water ponds and infiltration basins. During the preliminary review, the Engineering staff analyzed a feasibility .study that was conducted in the 1980's for the. storm water ponding system in this area. The basis forthe study included issues of high water levels on Grass Lake and the low-lying areas near Gramsie Road. The study area included the School District parcel and determined any drainage from future development be directed toward Evans Pond. located west of this site and not o the Suzanne Pond (see attachment). The study from 1986. resulted in ponding and storm water pumping station improvements for this area that recognized a transfer of runoff from .approximately 10 acres .from the .Grass Lake Basin to the Snail Lake Basin.. Accordingly, City staff required the developer to modify the plans to re-route the water to a storm water system that directs water north to a pond located. in Snail Lake... Regional Park before discharging into Snail Lake. Minor modifications addressing emergency .overflows, easements and maintenance are also needed to the plan. Recommended Board Action: No formal action is required; however, Board members may want to discuss and/or acknowledge the City staff's interpretation of the drainagexelatedisues of the proposed development.
