EXHIBITS Page 50 <br />Residential <br />This category is expressed in gross acre density ranges. Using gross acres, approximately 32 <br />percent of the area is available for auxiliary uses, such as streets, elementary and junior high <br />schools, neighborhood parks, other public facilities, neighborhood commercial services, and <br />churches not actually shown on the Metro Plan Diagram. Such auxiliary uses shall be allowed <br />within residential designations if compatible with refinement plans, zoning ordinances, and other <br />local controls for allowed uses in residential neighborhoods. The division into low, medium, and <br />high densities is consistent with that depicted on the Metro Plan Diagram. In other words: <br />Low density residential-Through 10 units per gross acre <br />Medium density residential-Over 10 through 20 units per gross acre <br />High density residential-Over 20 units per gross acre <br />These ranges do not prescribe particular structure types, such as single-family detached, duplex, <br />mobile home, or multiple-family. That distinction, if necessary, is left to local plans and zoning <br />ordinances. <br />While all medium and high density allocations shown on the Metro Plan Diagram may not be <br />needed during the planning period, their protection for these uses is important because available <br />sites meeting pertinent location standards are limited. <br />As of January 1, 1977, density of all existing residential development within the 1990 Plan <br />projected urban service area was about 3.64 dwelling units per gross acre. For new dwelling <br />units constructed during 1986 to 1994, the net density was 7.05 dwelling units per acre in the <br />UGB based on the RLID data. The estimated overall residential net density for all residential <br />development has climbed from 5.69 dwelling units per are in 1986 to 5.81 dwelling units per <br />acre in 1994. This Metro Plan, including the Metro Plan Diagram, calls for an overall average <br />of about six dwelling units per gross acre for new construction through 2015, the planning <br />period. By realizing this goal, the community will benefit from more efficient energy use; <br />preservation of the maximum amount of productive agricultural land; use of vacant leftover <br />parcels where utilities are already in place; and more efficient, less costly provision of utilities <br />and services to new areas. This higher overall average density can only be achieved if the cities <br />explore, and when feasible, in light of housing costs and needs, adopt new procedures and <br />standards including those needed to implement the policies in the Residential Land Use and <br />Housing Element. <br />The UGBs will be modified, as necessary, to ensure an on-going, adequate, available land supply <br />to meet needs.
