Program description
Background: In July 2024, the Legislature approved Chapter 83 (SB 867, Allen), authorizing a $10 billion bond measure entitled the “Safe Drinking Water, Wildfire Prevention, Drought Preparedness, and Clean Air Bond Act of 2024.” Largely designed to increase the state’s resilience to the impacts of climate change, the measure was placed on the statewide ballot as Proposition 4 and subsequently approved by voters in November. This bond measure builds on significant funding for climate-related programs—principally from the General Fund—the state made in recent years. Applications: Applications will be submitted in two phases: a Concept Proposal and a Full Application. Applicants will first submit a Concept Proposal that will be reviewed by RMC staff for consistency with RMC goals, any specific program priorities, and the strength of the proposed project. In addition, RMC staff will look at all Concept Proposals for location, need, project type, readiness, threats, cost, and cost share. RMC staff will offer applicants feedback regarding alignment with priorities, overall merit, and any ineligible costs. RMC staff will select Concept Proposals to move forward and will invite selected applicants to submit Full Applications. Applicants will be provided the Full Application upon RMC invitation. RMC staff are available to work with Applicants during the preparation of the Full Application, as needed. RMC may request Applicants to revise and resubmit Full Applications, as necessary. It is strongly recommended that prospective applicants contact RMC staff for a consultation prior to submitting a Concept Proposal.
