Property Tax Resources · Somervell County, Texas
Dinosaur Valley, Glen Rose, and Comanche Peak nuclear country — Somervell County’s $3,697 median annual bill is disproportionately high for a small county, driven by DFW spillover and the nuclear plant’s commercial tax base.

🔴 2026 Protest Deadline: May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Miss this date and you waive your right to protest.
Somervell County is one of the smallest counties in Texas by area and population, but carries one of the highest median property tax bills relative to its size — driven by two forces: Comanche Peak Nuclear Power Plant, which provides a massive commercial tax base that funds the county’s infrastructure, and DFW recreational buyers who have discovered Dinosaur Valley State Park and the Paluxy River as weekend destinations just 90 minutes from Dallas.
At 1.26%, Somervell County’s effective rate is above the national median. But the $3,697 median bill — driven by rising recreational property values — is a real burden on longtime local residents who aren’t selling to DFW buyers. More than half of those who protested in 2024 achieved reductions. Your deadline is May 15, 2026.

“No person’s particular services shall be demanded, nor property taken or applied to public use, unless by the consent of himself or his representative, without just compensation being made therefor.”
— Section 13, Declaration of Rights, Republic of Texas, 1836Somervell County has dinosaur tracks in the river and a nuclear plant on the Brazos — one of the most unlikely combinations of natural heritage and industrial infrastructure in Texas. The founders wrote that no property shall be taken without consent and just compensation. When DFW recreational demand inflates Glen Rose values beyond what local incomes support, the protest system is the correction. Look up your value. File your protest. Dinosaur Valley country deserves fair assessment.
