Chapter 3 System Description THE CITY OF PL£ASANTON Though both Plan Bay Area and RHNA address the amount and location of new housing development in the region, they are different types of planning processes. Plan Bay Area is a policy -driven land use and transportation framework that results in various projections of growth for different areas (i.e., a "ground up" model). RHNA, on the other hand, is a process whereby a pre -determined number of housing units is distributed among local jurisdictions, based on factors intended to result in an equitable distribution of those units. Another key difference between the two is that Plan Bay Area covers an approximately 30 -year planning horizon (2020-2050), whereas RHNA covers an 8 -year period from 2022-2030. Despite these differences, by law, the RHNA must be "consistent" with Plan Bay Area. ABAG has determined RHNA and Plan Bay Area to be consistent because the amount of housing growth from the 8 -year RHNA would not exceed the 30 -year growth level at the county and sub -county geographies used in Plan Bay Area. ABAG published the Draft RHNA Methodology Release in December 2020 to support Plan Bay Area 2050; this methodology has been used to develop "illustrative" RHNA allocations for each city and county in the region. Allocations will be finalized in 2021 through the remaining steps of the RHNA process. The proposed allocation for the City, which may be subject to revision and refinement, is 5,965', which is below the City's projected household projections. Although the City's RHNA allocation may not affect its long-term water demand projections, it may accelerate the rate at which demand increases in the nearterm. ABAG will approve a Final Methodology and issue Draft Allocations in spring 2021. This will be followed by an appeal period, with ABAG issuing Final Allocations by the end of 2021.
