Disadvantaged Unincorporated Communities – DUCs

Senate Bill 244 was a significant piece of LAFCO related legislation passed in 2011. This bill required LAFCO to make determinations regarding “Disadvantaged Unincorporated Communities” (DUCs). Disadvantaged Unincorporated Communities are defined as inhabited territory that constitutes all or a portion of a community with an annual median household income that is less than 80 percent of the statewide annual household income (MHI).

The MHI data is from the U.S. Census Bureau – American Community Survey 2015-2019. The State MHI for this period was $75,235. The qualifying income for a DUC is 80 percent of that figure, $60,188. The attached maps are utilizing the latest U.S. Census Bureau 5-year data set.

State law requires identification and analysis of service issues within DUCs as part of municipal service reviews (MSRs) and sphere of influence (SOI) reviews. State law also places restrictions on annexations to cities if the proposed annexation is adjacent to a DUC.

DUCS identified below are the results of our efforts to date. These represent all DUCs within Riverside County including unincorporated areas of the County. In addition to DUCs within and near City sphere’s of influence.  These maps will be updated on an ongoing basis, if needed.

The charts below provides a listing of the DUCs identified for the entirety of Riverside County areas to date.

For any questions regarding DUCs please contact Assistant Executive Officer, Crystal Craig at (951) 369-0631.
