Where Trinchera Creek Estates is

Most of the subdivision lies about 5 to 8 miles south and southwest of Blanca, on the valley floor south of US 160, with smaller pieces farther south. Trinchera Creek crosses the area, which gives the subdivision its name. County Road 12 and the lettered roads X, Y and Z run nearby. Most lots fall in the Blanca ZIP code area, 81123.

The land is flat to gently rolling at about 7,650 to 7,750 feet, with Mount Blanca to the north. The plat has eight units. On your tax bill, the legal description starts with T.C.E., then the unit, block and lot.

Lot sizes and what lots sell for

In the county parcel map, about 60 percent of lots measure close to 5 acres and about a third run 5.5 to 10 acres, most of those near 10 acres. A few tracts are larger.

We did not find a public source that tracks sale prices for Trinchera Creek Estates alone, so these are ZIP and county figures. Recent market data for ZIP 81123 (Blanca) shows a median land sale of $6,750 across 80 sales. Across Costilla County, lots of 5 to 10 acres had a median sale of $9,000 across 219 sales, and lots of 10 to 20 acres had a median of $22,250 across 26 sales. Land took about 152 days to sell on average.

Water, wells and the creek

The subdivision has no water system. A home needs a private well or a buried cistern of at least 500 gallons with hauled water. The Colorado Division of Water Resources (DWR) issues well permits. On a lot under 35 acres, a small exempt well is usually limited to household use inside one home, and wells in subdivisions approved on or after June 1, 1972 get extra review. The Rio Grande groundwater rules exempt only small wells that meet that law.

We did not find an augmentation plan for Trinchera Creek Estates in state records. Check your lot in DWR's Well Permit Search before you sell.

Roads, access and power

Lots are reached by dirt roads laid out on the plat. Some interior roads are rough, and low spots near the creek can be wet. Costilla County requires a Road Access permit before you build a driveway on a vacant lot unless one was issued before; the form lists a $200 fee.

The San Luis Valley Rural Electric Cooperative serves Costilla County. Most vacant lots have no line nearby, so owners use solar or ask the co-op about a line extension. We buy lots with no road access too.

Camping, RVs and building rules

We did not find an active owners' association for Trinchera Creek Estates. Recorded restrictions may still exist, and the county does not enforce them.

Costilla County rules apply to every lot. Staying in an RV or tent on the same parcel for more than 14 days total in any three months needs a Long-term Camping Permit. An RV may not serve as a full-time home or as storage. To live in an RV while you build, the county asks for a construction permit, a well permit or cistern, and an approved septic system that the RV hooks into.

A home needs a septic (OWTS) permit first; the new-permit fee is listed at $500. The home must be at least 600 square feet with a kitchen and a bathroom, one home per parcel. Manufactured homes must be 1976 or newer. The county does not enforce private covenants. Rules and fees change, so call Planning and Zoning at 719-937-7668 before you count on them.

Property taxes

The Costilla County Treasurer in San Luis sends the tax bill for Trinchera Creek Estates lots. Pay half by the last day of February and half by June 15, or the full year by April 30. Late taxes add 1 percent interest per month. Check your balance on the Treasurer's page or call (719) 937-7672.

Unpaid taxes lead to a tax lien sale. The county holds it online each fall, and the 2026 sale starts November 3. The buyer of the lien does not own your lot. You can still redeem by paying the taxes, interest and costs until a treasurer's deed is issued. Read more on our Costilla County back taxes page.
