City of Arden Hills - Comprehensive Plan - DRAFT <br />6.4.7 Development Capacity and Net Residential Density <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 />According to the 2005 land use data provided by the Metropolitan Council, <br />there were J,318 acres of net residential land in Arden Hills, which <br />includes City streets adiacent to residential areas. The United States <br />Census Bureau lists.' 017 ousin units in Arden Hills in 2000. <br />Therefore, the residential density in the developed portion of Arden Hills is <br />approximately 2.29 -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 land uses will be able to accommodate <br />development atlhree units per net residential acre, <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 that could be built ata density of at least three per acre. <br />The unapproved concept plan for the TCAAP 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 />6.4.8 Staged Development <br />As previously noted, the development timeline for the proposed TCAAP <br />redevelopment is not yet known.
