Jurisdictional Authority The City has relied on the 1974-75 wetland m\ ontory as the definitive mapping of wetlands protected via City ordinance Sections 7S*l 109 thru 78-1 1 12 (fcimerly Chapter 10.55 Subs. Stlu-u S). The advent of the Minnesota Welland Conserv-ation Act (WCA) in the early I990 ’s resulted in an additional layer of protection ofwetlands, established a variety of parameiers for defining and delineating w etlands, and established certain tiine&amcs for applicability of those parameters The City has authonzed the NLnnehaha Creek Watershed District (MCWD) to act as the Local Govemmeni Unit iLG’J) for administration of the WCA. Wetlands are also Federally regulated by the .Army Corps of Engineers Tlic City code fu.“.ctionaHy ignores wetlands not sh'^wn on the 1974-75 Orono Wetland Diventory, but many small w etland basins not shown on that inventoiy arc shown on the various maps used by the MC\\'D for w ctland administration. These maps include the National Wetland Inventoiy maps (1 9S9 USDIFWS); tire MnDNU's Protected Waters and Wetlands maps (19S3) and MCWD’s “Functional Assessment of Wetlands” (2003) Additionally, the MCWD requires delineation of wetlands for all development w here a w etlan.i may be involved. Due to the WCA wetland delineation guidelines, many small Type I and II w ctlands w hich il.e City never contemplated protecting, arc proiccicd under WC.A rules. Current Wetland Status of “1925" Lakeview Terrace Under Citv' Ordinance 78-1 1 12, virrually tlte entire lot is considered as a City-protected w ctland, and has carried that status since the City maps were adopted in the 1970's The nor.hcasterly poiiion of the propery has been rlclincatcd by the applicants ’ w etland consultant as WC.A protected w etland. It has been delineated as a "Type 2 (PEM13) w etland dominated by reed canary grass along with some lake sedge and a few red-esi er dogw oeds ” Thi s delineation dees not include the ditch area. On ? lay 10 the applicant w as advised, per the recommendation of the City’s wetland consultant, to have the MCWD cenify- the wetland boundaries. Ihis cenification is still pending. The wetland on Lot 2 is 005 m^ped on the N^VT maps nor the DNlt. maps, and is mapped on the MCWD’s "Functional Assessment ” maps.
