Because there are exis�ng walking paths and farm access roads, the clearing work is an�cipated to be minimal for the majority of the trails to be constructed. New trees and shrubs will be planted near the parking lot. E. Wetland Resources The property has two wetlands indicated in previous delinea�ons last conducted in 2001. The first wetland is a seven acre wetland sedge meadow. The second wetland is the catail marsh on the southwest shore of Oneka Lake. A wooded glacial beach ridge consis�ng of oaks and variety of na�ve shrubs separates the two wetlands. Construc�on in the park is not proposed to disturb or impact the wetlands. Water quality of Oneka Lake will con�nue to be protected. The shoreline will con�nue to be buffered by the ice ridge throughout most of the property. A fishing pier is proposed to be constructed at an exis�ng separa�on in the ice ridge. The pier, trails, and other park ameni�es will have minimal impact on the overall hydrologic se�ng. The east side of Oneka Lake consists of 10 acre lots. This land use se�ng is likely to be maintained and the hydrologic se�ng maintained. The west side of Oneka Lake is likely to see addi�onal residen�al development. The city-owned property immediately north of Bernin Park was acquired through park dedica�on in partnership with the developers. A significant buffer of the shoreline was maintained in addi�on to the recrea�onal benefit of trail construc�on. The natural buffer and recrea�onal trail is likely to con�nue north along the west shoreline of Oneka Lake with future residen�al development. This will protect the water quality of the lake and prevent nega�ve impacts due to drainage. F. Geologic and Physiographic Features Bernin Park is located within the major landform of the Anoka Sand Plain, which consists of level to gently rolling topography. The Anoka Sand Plain is composed of fine sand deposited by streams and large lakes over glacial �lls. The project area has soils formed dominantly in outwash. Much of the project area contains Isan� and Lino soils. The ice ridge, which follows the shoreline is gently sloped and vegetated with grasses and trees. G. Flood Plains There are three Rice Creek Watershed District floodplains within the general park areas. East (Oneka Lake) with the NAVD 88 eleva�on of 931.36, West (a small depressed area on the west side of the parcel) with the NAVD 88 eleva�on of 930.29, and South (the exis�ng pond on the parcel south of the park) with the NAVD 88 eleva�on of 931.17. Any fill within the two floodplains on the park property will have compensatory storage created, as needed. H. Air Quality/Noise The proposed park improvements will generate a minimal amount of vehicle traffic and any increase in vehicle related air emissions would be negligible. Construc�on of the proposed improvements would generate some dust and noise during the construc�on period of four to six weeks. The city would
