Sacramento-San Joaquin Delta National Heritage Area

The Sacramento San Joaquin Delta National Heritage Area (NHA) was created by Congress (PDF) in 2019. It is the first – and so far only – NHA in California, a distinction that underscores the region’s historical and cultural value in a state better known nationally for its coastal cities and resources.

The Delta NHA boundary extends from Sacramento to Stockton to Vallejo with the junction of the Sacramento and San Joaquin rivers at its heart. The history of California’s Delta and Carquinez Strait is a rich tapestry of indigenous peoples and immigrants from around the world, natural beauty and wildlife and engineering marvels, bustling metropolitan areas and picturesque rural towns. The native peat soils provide for fertile cropland and its water supports 29 million Californians.

It focused on developing a collection of writings intended for high school and college readers as well as for those interested in the region’s rich culture and heritage. The project resulted in this book.

Administration of the NHA

As the local coordinating entity for the Delta NHA, the Delta Protection Commission is responsible for preparing a management plan, which is a continuation of the Feasibility Study (PDF) completed in 2012.

The Commission created a 15-member volunteer NHA Management Plan Advisory Committee – read its charter (PDF) – to develop the management plan.

The NHA Committee is scheduled to meet every month until the management plan is approved by the Secretary of the Interior. The next meeting will be held at 3 p.m., Thursday July 13, 2023. The agenda will be posted here at least 10 days before the meeting.
