CITY OF ST. ANTHONY VILLAGE WATER RESOURCES MANAGEMENT PLAN SECTION 2 Page 2 Appendix A. The four soil classifications are defined as follows: Group A - These soils have high infiltration rates even when thoroughly wetted. The infiltration rates range from 0.8 to 1.6 inches per hour. These soils consist chiefly of deep, well drained to excessively drained sands and gravel. Group A soils have a high rate of water transmission, therefore resulting in a low runoff potential. Group B - These soils have moderate infiltration rates ranging from 0.3 to 0.6 inches per hour when thoroughly wetted. Group B soils consist of deep moderately well to well drained soils with moderately fine to moderately coarse textures. Group C - These soils have slow infiltration rates averaging about 0.2 inches per hour when thoroughly wetted. Group C soils have moderately fine to fine texture. Group D - These soils have very slow infiltration rates typically less than 0.2 inches per hour when thoroughly wetted. Group D soils are typically clay soils with high swelling potential, soils with high permanent water table, soils with a clay layer at or near the surface, or shallow soils over nearly impervious material. The infiltration rates listed above come from the RCWD Watershed Management Plan, updated in 2013. The City of St. Anthony Village contains a mixture of many soils, including Hayden and Kingsley soils. These soils have an undulating, well drained, moderately coarse texture. The remaining soils are loam-textured till ranging from loamy sand to clay. Additional information on the geology and soil for the City can be found in the Ramsey County Soil Survey, the Hennepin County Soil Survey, and the Rice Creek Watershed District Watershed Management Plan. 2.4. Land Use The City of St. Anthony Village’s designation by the Metropolitan Council is that of a developed community, meaning that over 85% of it is developed. St. Anthony Village is essentially fully developed, with its 2018 Comprehensive Plan calling for a focus on redevelopment opportunities to enhance the City’s image. Low-density residential land uses comprise 43% of all of the City’s useable land. Medium density residential land uses comprise only 3% and high density residential land use comprise 5% of the City’s developable area. Commercial development occupies 2% of the City's land area, and industrial land uses occupy 5% of the City’s total land area. Parks and open space occupy 36% of the City's total land area. The remaining 6% of land in St. Anthony Village is designated as a Planned-Unit Development which entails a mixture of commercial, retail, and high density housing. The existing and future land uses in St. Anthony Village are shown on Figure 2 and Figure 3, respectively, in Appendix A. Land use data is an important factor for estimating surface water runoff. The hard or impervious surface areas associated with each land use greatly affect the amount of runoff generated from an area. Future land use projections indicate those areas that may be available for water resource enhancement and where improvements should be a priority. Significant changes in land use can increase runoff due to added impervious surfaces. The City of St. Anthony Village expects very little change in land use. The Metropolitan Council expects that household growth will be limited to infill development and redevelopment areas, which is consistent with the City's future land use plan. The City’s Comprehensive Plan indicates the addition of 23 acres of high density residential housing by 2040. 2.5. Public Utilities
