Climate Bond Grant Program Announcement

The Sacramento-San Joaquin Delta Conservancy Board voted to approve two new solicitation notices that will primarily be funded by the Proposition 4 Climate Bond.

1. The Delta Community, Environment, and Climate Grant Program: This program will fund multi-benefit projects in the Delta and Suisun Marsh.
2. A Small Grant Program: This program will fund projects under $100,000 that make transformative investments in the Delta's social, economic, scientific, and physical infrastructure.

The Conservancy will solicit proposals that focus on at least one of three priorities, as described below:

• Nature Based Solutions: Projects that help stop or reverse ongoing subsidence and reduce greenhouse gas emissions on highly organic soils by supporting farmers transitioning to rice cultivation or managed wetlands and providing them with technical assistance.
• Community Enhancement: Projects that improve outdoor access, preserve the Delta's heritage, or enhance the unique values of the Delta. Examples include planning, land acquisition, trails, parks, environmental education, or historic building renovations.
• Ecosystem Restoration: Projects that protect and restore the Delta and Suisun Marsh's natural resources, environment, and biodiversity. Examples include planning; education; habitat restoration; enhancement, and protection; watershed resilience; land acquisitions; and conservation easements.

The Conservancy expects to release these detailed solicitation notices in September 2026.

More information on these solicitations will be available on their website under the Proposition 4 Climate Bond Grant Program.
