Topography The site is located on the west side of U.S. Highway 169 and south of 197th Street, NW. The site elevations range from 1008 in the north portion of the site to 978 in the southeast corner. The site drainage generally flows from the north to the south with the exception of a drainage easement located in the west side of the property near the middle. B. Vegetation The project site is open with very sparse vegetation, except for a small group of trees in the extreme northwest corner and for the portion of the site within Lots 3 and 4 of Ridgewood East 3rd Addition that is heavily wooded. iC. Soils and Ground Water The soils, based on the Sherburne County soils survey, consist of sand and gravel. The open portion of the site appears to have been mined. Soil borings will be obtained to provide more detailed information on soil and ground water prior to construction. D. Wetlands A formal wetland delineation has not yet been done. The wooded area north of 194th Avenue contains two depressions, which may be wooded wetlands. V. STORMWATER MANAGEMENT The development plans show two stormwater basins for treatment and rate control of surface water runoff. These would comply with City standards. Based on the granular soils, these basins would not hold water unless they are lined. Unlined basins could serve as infiltration basins, if desired. The site has three existing drainage easements. These would need to be vacated and new easements provided at locations compatible with the development plan.
