Zoning File #1877 <br />October 22, 1993 <br />Page 2 <br />Perhaps a more pressing issue for the dev t loper is a concern about the number and extent <br />of wetlands delineated on the site by the developer’s ct)nsultants under new Federal guidelines. <br />Many areas not mapped as City designated wetlands nor previously preserved under City <br />ordinances, have been identified as "Type 1" wetlands throughout both proj 'ies. The <br />developer needs City decisions on whether these wetlands will be considered as dr^ ‘'uildable. <br />and whether septic system setbacks from these wetlands will be required. <br />Wetlands Issues <br />Orono’s 1975 mapping of wetlands through the Hennepin Conservation District included <br />mainly wetland Types 2, 3. 4. 5 anil 6. Our current code references the following documents <br />in defining the "protected area": <br />a. uses topographic quad maps (1" = 2,000 ’scale). <br />b. Orono's 1975 mapping by Hennepin Conser' ation District (1" = 200 ’ scale). <br />c. Flood Insurance Rate Maps and Flood Boundary Maps of various scales. <br />Department of Housing and Urban Development. 1978. <br />Our code defines wetlands as follows: <br />14. "Wetlands or marshland" - Lowlands covered with shallow <br />and sometimes temporary or intermittent waters and also <br />identifiable by wetlands vegetation and soil types. <br />15. "Wetlands vegetation types" - Including, but not limited to, <br />bulrushes, cattails, arrowhead, .sedges, marsh grasses as identified <br />by the Hennepin Soil and Water Conservation District and/or <br />Circular 39 of the United Slates Department of the Interior, Fish <br />and W'ildlife Service. <br />16. "Wetlands soil types" • Including, but not limited to. Marsh <br />(Maf Peal and Peaty Muck (Pa. Pm). Utke Beaches (Lc. Ixl). <br />Hamel (Ha), and Glencoe(Gc) as identified and classified by the <br />Hennepin Soil and Water Conservation District and/or Circular 39 <br />of the United States Department of the Interior, Fish and Wildlife <br />Service. <br />In 1975 there were certainly dozens if not hundreds of Type 1 wetlands in Orono. but <br />a decision was apparently made to protect mainly Types 2-6. hence only 3% of our protected <br />basins are T’ ne 1. This may have been done in the context that DNR was mainly protecting <br />Types 3. 4 and 5.
