Disadvantaged Communities

According to the 2012 Proposition 84 and 1E Guidelines, a "disadvantaged communitY" (DAC) is defined by the State of California as a community with an annual median household income (MHI) that is less than 80 percent of the statewide MHI (Public Resources Code (PRC), 75005(g)).

A community with an MHI of $48,706 or less is considered a DAC. Under past grant funding applications, approximately 19% of the Region's area qualifies as DAC, while 23% of its population lives within a DAC. As of the 2015 IRWM Plan update, this number had dropped to 19% of the region's population qualified as DAC, reflecting some recovery from the recent economic downturn.

Critical Water Supply and Water Quality Needs of DACs in the Region

Many of the water supply and water quality issues facing DACs in the Region relate to requirements to maintain drinking water quality that meets applicable standards, the threat of damage from flooding, and a strong reliance on Delta supplies. Increase costs of supplies or treatment have disproportionately adverse effects on DACs, whose limited resources may threaten their access to drinking water if costs grow too high. Bethel Island, which is entirely DAC, relies on groundwater for its drinking water supplies. This groundwater has high levels of arsenic, and projects are currently being developed to address this issue.

Issues of special concern to DACs in the Region include:

  • Improved water supply reliability / reduced reliance on Delta supplies

  • Water quality of groundwater supplies used to supplement Delta supplies

  • Infrastructure renovations necessary to assure continued reliability of the minimum quality and quantity of water

  • Affordability programs to offset the rising costs of water service 

  • Flood and stormwater management projects designed to protect disadvantaged communities from flooding impacts

 

DACs and IRWM

The statewide IRWM Program has prioritized addressing water issues in DACs, and as such, has provided some incentives to encourage inclusion of DAC projects in funding applications, and to ease the requirements for DACs to receive funding. In general, projects which are located within DACs and address critical water supply and water quality needs of a DAC are eligible for a funding match waiver, and are eligible to receive implementation grant funding for planning projects that would lay the groundwork for a future implementation project. Consistent with statewide priorities and local and regional needs, the East Contra Costa County IRWM Program also considers addressing DAC needs a priorities.

Including at least one DAC project in a regional funding application has also traditionally provided additional and/or tie-breaker points during DWR's evaluation of applications. For the East Contra Costa County IRWM region, which lies within a highly competitive funding area on one side (San Joaquin) and must compete against a large, influential IRWM region in the other side (San Francisco Bay Area), including DAC projects can provide that extra edge to make a funding application successful.
