Buying a Home in Kings County, CA: NAS Lemoore Noise Zones & Corcoran Subsidence

Naval Air Station Lemoore's low-altitude jet noise and Corcoran's severe, ongoing land subsidence are two real, mapped factors most other counties don't have.

Kings County, anchored by Hanford and Lemoore, is a small, agricultural San Joaquin Valley county whose two most distinctive features are Naval Air Station Lemoore — one of only four Navy master jet bases in the country — and, on the county's eastern edge, some of the most severe land subsidence in the United States, centered on the town of Corcoran.

What’s the transfer tax in Kings County?

Kings County's rate is flat across the entire county at $1.10 per $1,000 of consideration, with no city imposing an additional surcharge — including Lemoore, which is chartered but still applies the standard $0.55 city rate.

Avenal, Corcoran, Hanford, and Lemoore all sit at the same combined $1.10/$1,000 total. On a $320,000 sale, that's $352 in transfer tax anywhere in the county.

How does NAS Lemoore jet noise affect buying property in or near Lemoore?

NAS Lemoore is the Pacific Fleet's primary light-attack jet base and generates significant low-altitude jet noise from routine flight operations. The City of Lemoore has created an overlay zone under the Navy's low-level flight path — the "Ground Control Approach Box" — that limits structure heights and requires noise-mitigation building standards for development within it.

The surrounding Air Installation Compatible Use Zone framework designates Accident Potential Zones (APZ 1 and APZ 2) near the flight tracks where noise-sensitive uses (homes, churches) and high-occupancy uses (food stores, shopping centers) are restricted, and the county maintains a roughly 3-mile agricultural buffer around the base to limit long-term encroachment. Check a specific parcel against the Kings County/NAS Lemoore Joint Land Use Study and Airport Land Use Compatibility Plan noise-contour and APZ maps before assuming standard residential development rules apply — some parcels near the flight corridor carry real building restrictions or mandatory sound-insulation requirements that don't apply just a few miles away.

Is Corcoran a special case for land subsidence?

Yes — the eastern county, around Corcoran, sits atop some of the most severe land subsidence documented anywhere in the country: the town has sunk as much as 11.5 feet over roughly 14 years due to groundwater over-pumping.

A stretch of the California Aqueduct near Corcoran has subsided enough (more than 10 inches along a 5-mile stretch, with faster drops during drought years) to threaten the canal's water-carrying capacity — this is an active, ongoing issue tied to San Joaquin Valley groundwater use, not a one-time event. Separately, the historic Tulare Lake basin re-flooded in spring 2023 after one of the wettest winters in a century, covering more than 100 square miles of farmland; only a 14.5-mile emergency levee kept the flooding out of Corcoran itself (population ~22,000, home to two of the state's largest prisons), and federal damage estimates for the broader event ran into the billions of dollars. For any property near Corcoran or the historic Tulare Lake basin footprint, check current FEMA flood zone status and ask directly about known subsidence in the immediate area.

Can I freely develop agricultural land in Kings County?

Not necessarily — Kings County is heavily agricultural (dairy, cotton, and field crops) and actively administers a Williamson Act agricultural-preserve program through its Community Development Agency.

Confirm Williamson Act contract status before assuming unrestricted development rights on rural-adjacent land.

Frequently asked

Does NAS Lemoore jet noise affect all of Kings County?

No — it's concentrated in a mapped corridor near the base under the Airport Land Use Compatibility Plan and APZ 1/APZ 2 zones. Check a specific parcel against the county's noise-contour maps rather than assuming county-wide impact.

Is there a city transfer tax add-on in Hanford or Lemoore?

No. Every incorporated Kings County city, including chartered Lemoore, sits at the same flat $1.10 per $1,000 combined rate — no city-level surcharge anywhere in the county.

How badly has Corcoran sunk, and does it still matter today?

Corcoran has sunk as much as 11.5 feet over about 14 years due to groundwater over-pumping, and it's an ongoing issue — the California Aqueduct nearby has also measurably subsided. This is active, not historical, and worth asking about directly for property near Corcoran.

Is agricultural land near the Tulare Lake basin at flood risk?

The basin re-flooded in spring 2023 after a historic wet winter, covering more than 100 square miles and coming close to overtopping the levee protecting Corcoran — checking current FEMA flood zone status for any property near its historic footprint is a genuine due-diligence step.
