• • Agenda Item 5B Environmental Board Meeting Date: January 26, 2005 Topic: Marshan Meadows, Bruggeman Properties, 7364 Lake Drive, Preliminary Plat Review. Background: Marshan Meadows Development Proposal is located East of Lake Drive, and North of Gethsemane United Methodist Church, and adjacent to Marshan Lake (Attachment 1). Existing Zoning is R -1. Proposed Zoning is R -1. The proposal consists of 11.41 acres of land. There are 21 proposed lots. The total upland area is 10.53 Acres. The proposed development is in a Shoreland Overlay District. The area would be serviced with City sewer and water. Analysis: Shoreland Area Attachment 2 shows the approximate Shoreland Area, Shore Impact Zone, ordinary high water area, and NPDES area of "Within 200 feet of Lake." The Shoreland Area is defined as within 1000 feet of a lake. Shore Impact Zone is defined as land located between the ordinary high water level of public water and a line parallel to it at a setback of 50 % of the structure setback. The Lino Lakes Handbook for Conservation Development defines the proposal area as within a Lake Protection Area. This means that extraordinary means should be taken to ensure the protection of Lake Resources. Surface Water Management Attachments 2 and 8 show storm pipes from the streets and lot runoff. Water is moved through Stormwater pipes from the North to a NURP on the SW side of the development. This water than flows through a swale to an infiltration pond North of the NURP. The proposed infiltration pond is a designed system intended to filtrate water, as well as infiltrate. Water then flows through a pipe to Marshan Lake. Lots on the south end of the development channel surface runoff through swales to the NURP. Plan should show access for pond and infiltration area maintenance. Permit Application has been reviewed by the RCWD. Conditional Approval pending Receipt of Changes has been issued. The report is attached as item 10. • Surface -water volume calculations should be verified with the City Engineer to be adequate for the 2, 10, and 100 -year storm event. Env. Bd.
