2.4.1.1 Land Use The project will be compatible with the land uses identified in the adopted comprehensive plan, Mixed Residential, and those adjacent to the project area. The project will include design features to mitigate impacts to adjacent public streets and improve pedestrian and bic�rcle mobility. The project is anticipated to be developed as a Planned Unit Development to allow fle�bilityT in residential design features `vhile still maintaining compliance `vith the Land Use designation. 2.4.1.2 Geology, Soils, and Topography Geologp Minnesota Geological Survey data within the PYoject site lists the bedYock as Wonewoc Sandstone and Eau Claire Formation with depths to the bedrock ranging from appro�mately 50 to 350 feet. There are no known or mapped sinkholes, shallow limestone, shallow aquifers, oY karst features identified within oY neaY the pYoject aYea. Soils and Topography There are appro�mately 110 acres of land within the project with a soil farmland classification rating of either "Farmland of State`vide Importance" or "All Areas are Prime Farmland". Ho`vever, there is currentlyT no land within the Project site that is cultivated for agricultural production. As a result, no faYmland will be taken out of production as a Yesult of the pYoject. The erosion capabilities of the soils are susceptible as described byT the NRCS Soil Erodibility- (K`v) Factor rating `vhich ranges across the site from 0.02 to 0.37. Construction activities will temporarilyT expose soils to an increased risk of erosion from wind and precipitation. Appropriate erosion and sediment control best management practices (BMPs) will be selected based on curYent site conditions and maintained thYough the duration of each construction phase to reduce the potential of sedimentation occurring to surface `vater resources or migrating offsite. TempoYaryr BMPs will be inspected and maintained (peY the NPDES Construction StoYmwateY Permit) until permanent vegetation and stabilization has occurred. PeYmanent BMPs will be incorporated into project design to minimize erosion during routine operational activities (post- construction�. A geotechnical evaluation of the site has been completed which included 22 soil borings across the site. A map of the boring locations and detailed description of the soils observed at each is included in E�ibit B— Geotechnical Report. TopographyT of the Project site, collected via LiDAR, is illustrated on Appendix A— Figure 6. Site elevations were shown ranging from 896 to 946 msl. Site topograph�r generally slopes downward towards the basin located neaY the centeY before continuing to the south. Some aYeas of steep slopes (12% oY gYeater) are pYesent within the site.
