The depiction of a historical-period property on an early map, whether a house, a ranch, a mining prospect, or an irrigation canal, is often the earliest (and sometimes the only) evidence that cultural features once existed in a particular place. Statistical Research used early maps as a regional preservation-planning tool by systematically examining a group of early maps of the county for depictions of cultural features. The typology will be used to plot the sites, distinguished by type, on a single map (or possibly on a series of maps) to be digitized by Pima County and incorporated into its GIS database.

The U.S. Department of Housing and Urban Development requires all government entities receiving federal low-income housing and community development funds to prepare an Annual Action Plan. This is a one-year plan to address the low-income housing and community development needs in the state of Arizona, with a special focus on serving the small cities and rural areas of the state. It consolidates the planning, application, and funding requirements for several programs funded by the U.S. Department of Housing and Urban Development: Community Development Block Grant; HOME Investment Partnerships Program; Emergency Solutions Grant; and Housing Opportunities for Persons with AIDS. The federal and state-funded housing and community development projects and programs described within the Action Plan are administered and implemented by ADOH, the Arizona Department of Economic Security, units of local or regional government, or non-profit agencies.
