Buying Land in Coryell County, Texas
Coryell County, seat Gatesville, holds most of Fort Hood's 342-square-mile footprint -- a fact that shapes both how much private land actually exists here and, less obviously, whether a wind energy project on remaining land can qualify for state tax incentives. Groundwater and septic permitting each run through a different, non-county body.
Fort Hood: a huge share of the map, and a compatibility study to know about
Fort Hood -- briefly renamed Fort Cavazos in 2023 under a Department of Defense Naming Commission review, then renamed back to Fort Hood in 2025 in honor of Col. Robert B. Hood -- occupies roughly 342 square miles spanning Bell and Coryell Counties, with most of that acreage inside Coryell County. That means a meaningful share of the county simply isn't available as private land at all. Coryell County, together with the City of Killeen and other regional partners, was a named study partner in the 2016 Fort Hood Joint Land Use Study (JLUS), which evaluates whether civilian growth and development near the installation stays compatible with its air and ground training, testing, and power-projection missions. The JLUS itself is a planning and coordination document rather than a zoning ordinance -- Coryell County has no general zoning authority to implement it as such -- but its recommendations can surface in county subdivision review, municipal ETJ rules near Killeen and Copperas Cove, and Fort Hood's own community-planning outreach. A buyer near the installation boundary should ask both the county and Fort Hood's community planner directly about any noise, lighting, or height concerns tied to nearby training or flight operations.
Wind energy: a real, countywide tax-incentive limit tied to Fort Hood
Texas's Senate Bill 277, signed in 2017 and effective for devices installed on or after September 1, 2017, prohibits granting Chapter 312 or Chapter 313 property tax abatements for a wind-powered energy device located within 25 nautical miles of a military aviation facility -- a measure aimed at protecting flight training routes and radar operations near bases like Fort Hood, where turbines up to 500 feet tall can conflict with helicopter training flown as low as 200 feet. Because Fort Hood's aviation facilities sit inside Coryell County itself, essentially the entire county falls within that 25-nautical-mile radius, meaning a wind project almost anywhere in the county would be ineligible for those specific state tax incentives (Chapter 313's broader school-district abatement program has since expired statewide on its own separate timeline, leaving Chapter 312 as the more relevant remaining constraint). This does not ban wind development outright, and it says nothing about solar leasing, which isn't covered by SB 277 at all -- see the dedicated wind-solar-leasing page for what this specifically does and doesn't affect.
Water, septic, and subdivision: three different bodies to check
Groundwater in Coryell County is regulated by the Middle Trinity Groundwater Conservation District, which Coryell joined in June 2010 alongside Bosque, Comanche, and Erath Counties. A well incapable of producing more than 25,000 gallons of groundwater per day generally qualifies for the district's exemption, subject to additional property-size and subdivision-related rules -- confirm the current thresholds and any subdivision-specific requirements directly with Middle Trinity GCD before drilling. Separately, septic (OSSF) permitting for Coryell County appears to route through TCEQ's Region 9 office in Waco rather than a dedicated county authorized-agent program, though this should be confirmed directly with the county, since authorized-agent status can change. The county's own Subdivision Regulations and Permitting Requirements were most recently approved June 8, 2021, and govern how a tract can be divided countywide -- get the current version and any recent amendments directly from the county before planning a land split.
Who to Call Before Buying Land in Coryell County
Coryell County has no general zoning authority and is not among the named Chapter 231 exceptions, so there is no planning_zoning entry above -- the closest thing to a land-use-compatibility framework here is the non-regulatory 2016 Fort Hood Joint Land Use Study. This research could not confirm with certainty whether Coryell County holds TCEQ OSSF authorized-agent status or routes permitting entirely through TCEQ Region 9 in Waco; confirm directly with the county's Environmental Office before assuming either way.
