The proposed trail connection across the wetland area and through the scenic easement will not affect the potential Blanding's turtle habitat or their mobility. A data search also identified two records of upland sandpipers within the northwest portion of Shoreview including a 1990 observation of the bird on this site, Upland sandpipers are not state or federally listed, but are noted as special concern species due to general population declines. 1.4.4 Water-Related Land Use Management Districts: Shoreland and Floodplain (a) Shoreland Rice Creek has been classified as a general development water by the DNR ,and the City of Shoreview's Shoreland Ordinance. The Rice Creek shorelanddistrictextends 300' landward from the bank of Rice Creek, or to the landward extent of the lOO-year floodplain, whichever is greater. None of the business park or residential structures will be located within the shoreland district and there will be no disturbance of steep slopes adjacent to floodplain to construct them. A portion of Rice Creek Parkway and the future trail connection from the project site to the existing Rice Creek North trail will be located within the shoreland district. Construction of the water main and trail will result in some disturbance of steep slopes and native vegetation, (b) Floodplain The project site includes minor portions of the 100-year floodplain associated with Rice Creek. There is also a Federal Emergency Management Agency (FEMA) designated floodplain (Zone A) along the Rice Creek North Corridor. There will be no floodplain impact for construction of the business park or residential structures. Approximately 1,400 linear feet of Rice Creek Parkway will lie within the Rice Creek floodplain on the Rice Creek North property. Approximately 7.8 acre-feet of floodplain will be filled in order to construct the roadway. 1.4.5 Surface Water Runoff The proposed project will increase the amount of impervious surface from existing 7 acres (2.9% of total watershed) to proposed 96 acres (40% of total watershed), (The total watershed is 238 acres which includes the 207-acre U ofM property, the 23-acre MnDOT property, and 8 acres of off-site fringe areas which are part of the subwatersheds contributing:to overall site runoff.) The proposed 96 acres of impervious surface is an approximate figure based on the current proposed project site plan. It would likely be further refined during the Planned Unit Development (PUD) final stage plan review process. Rice Creek Parkway south of the project site will affect an additional 3 acres of Rice Creek North property, none of which is currently impervious. Volumes and rates of runoff will increase proportionately. The quality of runoff will be decreased as it picks up pollutant loadings from hard surfaces and landscaped areas.
