Buying Land in Bent County, Colorado

Bent County is southeast Colorado plains and river-bottom farmland along the Arkansas, run day-to-day by a small county government -- a single Land Use Coordinator's office handles zoning and permits countywide. Most unincorporated land is zoned A-1 Agriculture, and a separate set of local rules specifically protects the county's historically irrigated farmland from being converted without review.

Countywide Zoning: A-1 Agriculture District

Generally favorable

Bent County has a real, adopted Zoning Regulations code (most recently reissued as a Planning and Zoning Manual, updated May 2025), not an informal or absent one. Most unincorporated land is zoned A-1 (Agriculture District), intended to protect farming and ranching uses and shield rural property owners from incompatible development. Confirm the exact zone and any applicable minimum lot size or setback for a specific parcel with the county's Land Use office rather than assuming A-1 applies everywhere.

Small Communities: Multiple Use District (M.U.D.)

Could not confirm

The unincorporated communities of McClave, Hasty, Caddoa, and Fort Lyon carry a separate M.U.D. (Multiple Use District) designation intended for areas already in a mixed-use pattern or transitioning toward one. A parcel in or near one of these communities may follow different allowed-use rules than the surrounding A-1 agricultural land -- confirm which zone actually applies before assuming county agricultural rules.

1041 Regulations on Historically Irrigated Farmland

Case-by-case / verify locally

Bent County has adopted its own 1041 regulations (Guidelines and Regulations for Areas and Activities of State Interest, originally 2016, amended 2021) under state law, and it specifically designates historically irrigated areas of the county as areas of state interest subject to a Board of County Commissioners permit process. If you're evaluating irrigated farmland with an eye toward changing its use, subdividing it, or transferring its water elsewhere, confirm with the county whether the parcel falls inside a designated area and whether a 1041 permit applies before assuming ordinary zoning approval is all that's needed.

John Martin Reservoir and Arkansas River Water Storage

Could not confirm

John Martin Reservoir, a U.S. Army Corps of Engineers dam and reservoir on the Arkansas River near Caddoa (completed 1948, authorized for flood control and irrigation), sits within the county and anchors both the local water-storage system and John Martin Reservoir State Park's recreation economy. This is a federal facility, not something a private landowner controls -- if a listing markets proximity to or a view of the reservoir, verify the parcel's actual relationship to Corps of Engineers land and any easement or flowage-easement boundary directly rather than assuming unrestricted lake access.

Zoning administered by a single Land Use office -- confirm directly, don't assume from third-party sites

Some third-party real-estate and land-buying sites describe Bent County as having "no formal zoning," but that doesn't match the county's own published Zoning Regulations, most recently reissued as a Planning and Zoning Manual (updated May 29, 2025). The regulations set out a real zone structure: an A-1 Agriculture District covering most unincorporated land, intended to protect the county's agricultural base and buffer rural landowners from incompatible uses, and a Multiple Use District (M.U.D.) applied to the unincorporated communities of McClave, Hasty, Caddoa, and Fort Lyon, where mixed uses already exist or are in transition. A subdivision or Planned Unit Development approval in the county also requires a water-related permit under the county's water-project regulations, in addition to zoning and subdivision review.

Day-to-day administration runs through a single Land Use Coordinator's office rather than a multi-person planning department -- a reflection of the county's small size (roughly 5,500-5,650 residents countywide, with the seat, Las Animas, home to about 2,300 of them). That's not a red flag, but it does mean there's no separate zoning-enforcement or long-range-planning staff to call for a second opinion -- the same office handles zoning questions, permit applications, and the Planning and Zoning Commission's docket. Confirm any zoning, setback, or permit question for a specific parcel directly with that office rather than relying on a generic online summary.

1041 rules protect the county's historically irrigated farmland -- a real check for ag-land conversions

Under Colorado's 1974 Areas and Activities of State Interest Act (HB 1041), counties can designate specific areas and activities as matters of state interest and require their own permit before certain development can proceed. Bent County adopted its own 1041 Guidelines and Regulations in 2016 and amended them in 2021, and the county's designated areas specifically include land that has historically been irrigated -- a direct reflection of the county's Arkansas River agricultural economy and the value the county places on keeping irrigated farmland in production. The Board of County Commissioners is the permit authority, and the process includes required public notice and a hearing before approval.

This matters most if you're evaluating a parcel of irrigated farmland with plans to change its use, subdivide it, or separate its water right for sale or transfer elsewhere -- exactly the kind of "buy and dry" scenario that has drawn attention on the Arkansas River in dry years, and one that's actively playing out in the county right now (see the farm-land page linked below for the specifics). Ask the Land Use office directly whether a specific parcel falls within a 1041-designated historically-irrigated area and what triggers the permit requirement before assuming a straightforward zoning approval covers everything you plan to do with the land.

The Arkansas River corridor and John Martin Reservoir

Bent County's identity runs along the Arkansas River, which crosses the county east-west through Las Animas and past the small communities of Hasty and Caddoa. John Martin Reservoir, a U.S. Army Corps of Engineers dam completed in 1948 after construction began in 1939 (with U.S. Representative John Martin an early advocate for the project), sits on the river near Caddoa and serves flood-control and irrigation-storage purposes for the broader lower Arkansas Valley -- it is also the centerpiece of John Martin Reservoir State Park. Agriculture remains the county's largest employment sector, consistent with its identity as an irrigated-farming and ranching county rather than a dryland-only plains county.

For a buyer, the practical point is that the reservoir and the river corridor are federally and state-managed features, not amenities a private parcel automatically comes with. A listing that markets river frontage, reservoir proximity, or irrigation-ditch access should be checked against the actual parcel boundary, any Corps of Engineers flowage easement, and the water right's documented status with the Division of Water Resources (Water District 14, Water Division 2) -- don't assume access or water delivery based on general area description alone.

Who to Call Before Buying Land in Bent County

Septic (OWTS) permitting runs through Bent County Public Health, a separate small department from the Land Use office listed above -- confirm current fees and inspection requirements directly with them. Well permitting is a state function through the Colorado Division of Water Resources (Bent County sits in Water District 14, Water Division 2) -- see the state hub. A dedicated county GIS office or online parcel-mapping portal was not independently confirmed as of this review; ask the Land Use office or Assessor's office for the current parcel-mapping resource.
