The legal description of the parcel is: A part of the NE 1 /4 of Section 5, ' T29N, R2OW, Washington County, Oak Park Heights, Minnesota. The parcel is a total of 1.33 acres. ' • Two wetland basins were delineated within the parcel bounds • Wetlands 1 and 2 are not indicated on the NWI map; AEC classified both ' wetlands as Shallow Marsh (Type 3, PEMF) wetland • Neither wetland is indicated on the Minnesota Department of Natural Resources 1 Public Water Inventory Map (PWI) • The Crystal Lake (non - hydric) soil series is mapped within the location of ' Wetlands 1 and 2 • Wetlands 1 and 2 are dominated by reed canary grass, cattail, hummock sedge, and Kentucky blue grass ' • The boundaries for Wetlands 1 and 2 were placed along the vegetation transition zone and an abrupt topographic break ' • AEC believes that Wetlands 1 and 2 may have been incidentally created and may be exempt from mitigation 1 Wetland ID Classification Type NWI PWI # Wetland 1 Shallow Marsh Type 3, None None PEMF 1 Wetland 2 Shallow Marsh Type 3, None None PEMF 1 1 1 1 1 1 1 1 1 i Figures 1 1 1 1 1 1 1 1 1 1 1 .-. `:+ * "� Driving Park �` lil , i I Wild Pine Orleans -F' ( I -iw u �¢ f r e.� 110 1� t ■G 'I va 9 'fw loc...' `rlR. tom• l _ f !

The legal description of the parcel is: A part of the NE 1 /a of Section 5, ' T29N, R20W, Washington County, Oak Park Heights, Minnesota. The parcel is a total of 1.33 acres. Methods AEC utilized the 1987 US Army Corps of Engineers Wetlands Delineation Manual and ' Midwest Regional Supplement to perform the wetland delineation. A United States Geological Survey (USGS) Map (Stillwater Quad) (Figure 1), the Minnesota Department of Natural Resources (MN DNR) Public Water Inventory (PWI) Map (Figure 2), the ' Washington County Soil Survey Map (Figure 3), and the National Wetland Inventory (NWI) Map (Figure 4) were reviewed prior to the site visit and used in the delineation process. The delineated wetland boundaries (approximate) are indicated on Figure 5 and are overlaid on a 2004 aerial image. AEC used the routine delineation method. ' Wetland classification followed methods described by the USACOE - St. Paul District; Eggers and Reed "Wetland Plants and Plant Communities of MN and WI ". The Circular 39 and Cowardin et al. classifications are given as well. The indicator status of plants ' was determined using the National List of Plant Species That Occur in Wetlands — Region 3 (Sabine 1999). In accordance with the Midwest Regional Supplement, the + and — have been removed from the vegetation indicator status. Pink pinflags were used to delineate the wetlands and were numbered sequentially. Sample points were taken to document the vegetation, soils, and hydrology indicators 111 within representative upland and wetland locations. Results Office Results Wetlands 1 and 2 are not indicated on the NWI or PWI maps. The Crystal Lake (non - 1 hydric) soil series is mapped within the area of Wetlands 1 and 2. Field Results Wetland 1 Wetland 1 is described as a Shallow Marsh (Type 3, PEMF) wetland. Wetland 1 is ' primarily dominated by reed canary grass (Phalaris arundinacea), hummock sedge (Carex stricta), cattail (Typha spp.), and Kentucky bluegrass (Poa pratensis). The adjacent upland area is dominated by Kentucky bluegrass, Canada thistle (Cirsium 1 1 arvense), common milkweed (Asclepias syriaca), and Canada goldenrod (Solidago canadensis). The wetland boundary was placed along the vegetation transition zone; there was an abrupt shift in vegetation between the reed canary grass and sedge (hydrophytic) and the Canada thistle and common milkweed (non - hydrophytic). Kentucky bluegrass was observed in both the wetland and upland areas (Kentucky bluegrass was formerly FAC- and non - hydrophytic under the original 1987 manual). A moderate to abrupt topographic ' break was observed along the wetland boundary; the boundary was placed at or near mid - slope. The wetland sample point met the F3 (Depleted Matrix) hydric soil indicator, the upland soil did not meet a hydric soil indicator. Additionally, soil was saturated at 16" ' below the surface at the wetland sample point; the soil was dry at the upland sample point. Wetland 2 Wetland 2 is described as a Shallow Marsh (Type 3, PEMF) wetland. Wetland 2 is primarily dominated by reed canary grass and cattail. The adjacent upland is dominated by Kentucky bluegrass, smooth brome (Bromus inermis), common milkweed, and Canada goldenrod. The wetland boundary was placed along the vegetation transition zone; there was an abrupt shift in vegetation between the reed canary grass and cattail (hydrophytic) and the Canada goldenrod and Kentucky bluegrass (non - hydrophytic). An abrupt topographic break was observed along the wetland boundary; the boundary was placed at or near mid - slope. Soil samples were not taken as the wetland boundary was abrupt, FACW and OBL vegetation was dominant and standing water was observed within the basin; hydric soils were assumed. It is likely that Wetlands 1 and 2 were incidentally created and may be exempt from mitigation. Wetland 1 is a narrow ditch running along the eastern edge of a bituminous parking lot. Much (if not all) of the runoff from the adjacent building and parking lot ' drains into Wetland 1; it is likely that Wetland 1 was dredged to channel runoff from the parking lot to the north and developed wetland characteristics over time. Wetland 2 is likely incidental as well; there is a large culvert at the east end of Wetland 2 that discharges runoff (into Wetland 2) from the properties to the east and drains to the west. AEC noted water from Wetlands 1 and 2 drains to the west and off of the subject property. 1 Discussion 1 Two wetland basins were delineated within the subject parcel. Both wetlands are described as Shallow Marsh (Type 3, PEMF) wetland dominated by reed canary grass, 1 hummock sedge, cattail, and Kentucky bluegrass. Wetland 1 was delineated by approximately 14 flags; Wetland 2 was delineated by approximately 12 flags. 1 r 2 1 I In order to be official the wetland delineation must be reviewed and approved by the Local Government Unit (LGU) and potentially other agencies (Local, State, Federal). 1 AEC recommends that the wetland boundary be located by a Professional Land Surveyor or located by a survey grade GPS unit. Any work within or adjacent to a wetland will require Wetland Conservation Act (WCA) permits (and potentially other permits). Please 1 consult with AEC if you plan on filling, draining, excavating wetlands within your project location.
