• Approximately 70% of the new units will be single family detached, 10% will be single family attached, and townhomes or duplexes and 20% will be multi family. This distri- bution is very similar to the current (2010) distribution of housing types.


• Gross Densities will equal approximately 3 units per acre for single family homes, 6 units per acre for single family attached homes, and 12 units per acre for multi-family homes.


• Land designated for residential development during the planning period will be twice the area needed for actual construction to provide market choice and prevent artificial inflation of land cost.


Under these assumptions, residential land need is calculated as follows:


• The cumulative housing unit need (see previous section) is split up by housing unit type (single family, multi-family, etc.).
