II PETERSON ENVIRONMENTAL CONSULTING, INC. December 13, 2000 Mr. Ed Vaughan 1432 Pheasant Hills Drive Lino Lakes, Minnesota 55038 Subject: Wetland Delineation Report, Pheasant Ridge Island Site Lino Lakes, Minnesota PEC Project No. 2000 -087 Dear Ed: Peterson Environmental Consulting, Inc. (PEC) has completed the delineation of jurisdictional wetlands on Pheasant Hills Island Site in Lino Lakes, Minnesota. The site is generally located south of Wards Lake and northeast of the terminal cul -de -sac of Ruffed Grouse Road in the NW 1/4 Sec 27, NE 1/4 Sec 28, T31N R22W, Anoka County, Minnesota (Figure 1). We delineated two wetlands on the site (Figure 2). The closed polygon designated as Basin A represents non- jurisdictional upland on the island. The line designated Basin B represents the boundary between upland (west) and wetland (east) in the proposed island road - access location. The delineation is preliminary because it was conducted outside the normal growing season. We will need to verify the boundary in the spring after the start of the growing season (generally after April 28), however, we do not expect the boundary to change substantially. METHODOLOGY Wetlands were delineated in accordance with the methodology set forth in the Corps of Engineers Wetlands Delineation Manual (1987 Manual). It should be noted that the impact of on- or off -site hydrologic alterations are not be fully accounted for when routine delineation methods are used. The boundary between the upland and wetland was determined through a routine analysis of the vegetation, soils and hydrology. Plant species within the wetland/upland ecotone were catalogued as to their percent cover and wetland indicator status according to the Daubenmire Cover Scale (Northwest Scientist 33:43 -64; 1959) and the National List of Plant Species that Occur in Wetlands; North Central Region 3 (USFWS Biological Report 88(26.3); May 1988), respectively. When a plant has not been identified to its specific epithet, a plant indicator status has not been assigned. Hydrophytic plants are considered predominant 1355 Mendota Heights Road, Suite 100 e Mendota Heights, Minnesota 55120 -1112 s 651- 686 -0151 ■ Fax 651- 686 -036.9 E -mail: Pec1nc@PETERSONENV.com
