Measure W would retain the rules of the existing measure which allow the UGB to be enlarged to accommodate affordable housing with a five acre limit each calendar year and a total limit of twenty acres over the 20-year life of the ballot measure. However, instead of requiring that housing projects eligible for this exception be “primarily” for low and very-low income housing, Measure W requires the project to be 100% affordable, with at least 51% being affordable to low and very-low income.
