<br /> <br />City of Arden Hills - Comprehensive Plan - DRAFT <br /> <br />property is aiso anticipated to have affordable housing, though an exact <br />number or percentage has not been determined. <br /> <br />All TCAAP redevelopment information is subject to change once a final <br />land use and redevelopment plan is selected. <br /> <br />6.4.7 Development Capacity and Net Residential Density <br /> <br />The Metropolitan Council's 2030 Regional Development Framework <br />requires an average net residential density of at least three units per net <br />residential acre. Densities lower than this are not an efficient use of the <br />region's sanitary sewer infrastructure. Net residential acreage is <br />calculated by subtracting wetlands, water bodies, public parks, arterial <br />streets, and identified natural resources that are protected by ordinance <br />from gross acres. The number of net residential acres is then divided by <br />the number of lots to determine net residential density. <br /> <br />According to the 2005 land use data provided by the Metropolitan Council, <br />there were ~.. ...~, of net residential land in Arden Hills. The United <br />States Census Bureau lists 2,994 households in Arden Hills in 2005. <br />Therefore, the residential density in the developed portion of Arden Hills is <br />approximately 2.27 residential units per net residential acre. While this is <br />below the three units per net residential acre required by the Metropolitan <br />Council, the City is not required to raise densities in the built portion of <br />Arden Hills. However, all future development will need to be developed at <br />a minimum of three units per net residential acre or greater. <br /> <br />There are no expected land use changes that would result in a reduction <br />in net residential density in the developed part of Arden Hills. The vacant <br />residential land south of Highway 96 and 10 is already zoned for <br />development at densities of at least three or more units per acre. <br /> <br />The unapproved concept plan for the TCMP property includes 168 acres <br />of residential area and 1,750 residential units for a preliminary average <br />density of 10.4 units per net residential acre. This density is only <br />preliminary because wetlands, parks, and protected natural areas have <br />not been removed from the 168 acres that are anticipated to be used for <br />residential development. The densities in the residential areas will be <br />varied to allow for a variety of housing types. <br /> <br />DRAFT <br />4/18/2008 <br /> <br />34 <br />
