Buying Land in Sacramento County, California

A capital county with a genuinely distinct Delta portion

Most of Sacramento County is urban and suburban -- the city of Sacramento itself, plus Elk Grove, Folsom, Citrus Heights, Rancho Cordova, and Galt -- built on ordinary California zoning and general plan frameworks. But the county's southern and western edge drops into the Sacramento-San Joaquin Delta, a landscape of historic river towns (Locke, notable as one of the only towns in the US built by and for Chinese immigrant farmworkers, plus Walnut Grove, Hood, and Courtland), reclaimed farmland, and a dense network of sloughs and levee-lined channels.

The Delta's levee system and reclamation districts

Much of the Delta's farmland was reclaimed from tidal marsh in the late 19th and early 20th centuries by local reclamation districts -- special districts still responsible today for maintaining the levees that keep river water off land sitting, in many cases, below the adjacent channel's water surface. This is not a generic floodplain in the FEMA sense alone; it's a purpose-built, gravity-dependent flood-control system with real maintenance obligations and real failure risk, and Sacramento County has direct experience with that risk given its position at the confluence of two major rivers.

The Sacramento Area Flood Control Agency (SAFCA), formed in 1989, was created specifically because the greater Sacramento area was recognized as carrying flood risk unusual for a major American urban center, given how the American and Sacramento Rivers converge near downtown. For any Delta-area parcel, confirm the responsible reclamation district, its current levee condition and assessment obligations, and the parcel's FEMA flood-zone designation directly -- see the dedicated flood-zones page below for more on how the Delta's statutory framework works.

A statutorily defined Delta, with its own land-use overlay

California's Delta Protection Act (1959, substantially expanded in 1992) legally defines the Sacramento-San Joaquin Delta and created the Delta Protection Commission to oversee land use within it, dividing the area into 'primary' and 'secondary' zones with different levels of state-level land-use review. The Sacramento-San Joaquin Delta Reform Act of 2009 added the Delta Stewardship Council and its own regional 'Delta Plan,' emphasizing the co-equal goals of water supply reliability and Delta ecosystem restoration.

For a buyer, this means a Delta-area Sacramento County parcel can be subject to state-level land-use policy specific to the Delta, on top of ordinary county zoning -- confirm whether a target parcel sits in the primary or secondary Delta zone, and what that designation means for any development plans, directly with the county and the Delta Protection Commission.
