LAKE MINNETONKA CONSERVATION DISTRICT MN Shoreland Management Rules Draft Review Forum, 9/30/88, Page 2 recommended zoning would pre-empt local zoning. Some flexibility with these provisions is possible. Zoning - 1, page l8, specified new standards, including setback, for single, duplex, triplex and ivad residential lots. Guest cottages are controlled. Controlled Access Lot Frontage Requirements. Increase in requirea lake frontage is dependent upon ratio of lake size to shore length (acres/mile). Lake Minnetonka is a General Development lake class with sewer, with 14,000 acres and 125 miles of shoreline, including islands; it falls in the 101.200 ratio size, the required increase in frontage for a controlled access lot being 20% (see pages 21 and 24). Structure Setback Standards, line 15, paL-e 25, drew questions concerning the SEPTIC SYSTEM as being the appropriate setback measure, rather than the building. Such a change poses considerations of a building's position on a lot depending on lot size, slope, as it affects septic system placement. Height, page 27, for residential dis'ricts, is proposed for reduction from 35' to 23', from ground level. Accessory Structures are similarly proposed to a 10' height limit. Shoreland Alterations, page 29, contain significant controls to prevent erosion into public waters, preserve shoreland esthetics. Standards for Commercial, Industrial, Public and Setsi-Public Uses, page _)5, .r.troduces standards where water -oriented needs are to be served. Stormwater Management, page 36, introduces standards .or all permit issuances. New stormwater outfalls re,,iire filtering or settling of suspended solids and skimming of surface debris before discharging into pro- tected waters. The balance of rules requiremenrs were scanned, no concerns expressed `y the group. Joint Exercise of Powers, page 54, was brought to the group's attertion _)y Gene Strommen as an opportunity for the 14 Lake Minnetonka borler communities to jointly develop and administer shoreland management contrcis as allowed in Minnesota statutes. The City of Wayzata did present a ccpv of its shoreland ordinances as an example ?0' their progress on the subje.'..
