San Francisco Bay Area Draft Regional Housing Needs Allocation, 4'h Revision A jurisdiction's share of the Regional Housing need is assigned according to its percentage share of regional household growth, employment growth, existing employment, and household and employment growth near transit: (Household Growth x .45) + (Employment Growth x .225) + (Existing Employment x .225) + (Household Growth near Transit x .OS) + (Employment Growth near Transit x .OS) Growth is during the RHNA planning period (2007 - 2014). The transit factors refer to growth that occurs within % mile of existing fixed transit stations in the jurisdiction. 2. Regional Allocations of Housing Units based on Affordability There are two primary goals of the RHNA process: 1) increase the supply of housing and 2) ensure that local governments consider the housing needs of persons at all income levels. The allocation method requires that each local jurisdiction plan for income-based housing relative to the regional average. The income allocation scenarios give each jurisdiction 175 percent of the difference between their 2000 household income distribution and the 2000 regional household income distribution. The regional average distribution of household incomes is as follows: • Very Low, 23 Percent Households with income up to 50 percent of the county's area median income (AMl7 • Low, 16 Percent Households with income between 50 and 80 percent of the county's AMI • Moderate, l9 Percent Households with income between 80 and 120 percent of the county's AMI • Above-Moderate, 42 Percent Households with income above 120 percent of the county's AMI The first step in the income allocation process is to determine the difference between the regional proportion of households in an income category and the jurisdiction's proportion for that category. This difference is then multiplied by 175 percent to determine an "adjustment factor." Finally, this adjustment factor is added to the jurisdiction's initial proportion of households in the income category, which results in the total share of the jurisdiction's housing unit allocation that will be in that income category. Using the 175 percent factor and the City of Oakland's very low income category as an example, 36 percent of households in Oakland were in this category, while the regional total was 23 percent. City Jurisdiction Regional Adjustment Total Proportion Proportion Difference Multiplier Factor Share Oakland 36 23 -13 175% -23 13 The diference between 23 and 36 is -13. This is multiplied by 175 percent for a result of - 22.75 (rounded to 23). This is then added to the city's original distribution of 36 percent, for a _lugust 2UU,, P:-ge 11
