The City is required to provide enough suitable land to accommodate 20-year land needs each time the UGB is evaluated in order to meet the requirements of Goals 9 and 10 for Employment and Housing land, respectively. As noted at the beginning of this Chapter, Bend’s Urbanization Report presents an analysis of where and how Bend’s future growth will be accommodated through growth on vacant land, infill/redevelopment, and UGB expansion. In order to ensure that the City’s available land can accommodate the growth projected, the City has adopted “efficiency measures” in the Development Code, which are supported by policies in this Chapter as well as the Housing and Employment Chapters. Key components of the efficiency measures include minimum densities for each urban residential plan designation (and the corresponding zoning district), increased minimum densities for large master plan sites, and eliminating barriers to efficient development, such as overly restrictive lot size requirements in medium- and high-density zones.
