Tex. Local Government Code § 284.105

(a) A network provider must obtain advance approval from a municipality before collocating new network nodes or installing new node support poles in an area of the municipality zoned or otherwise designated as a historic district or as a design district if the district has decorative poles. As a condition for approval of new network nodes or new node support poles in a historic district or a design district with decorative poles, a municipality may require reasonable design or concealment measures for the new network nodes or new node support poles. A municipality may request that a network provider comply with the design and aesthetic standards of the historic or design district and explore the feasibility of using certain camouflage measures to improve the aesthetics of the new network nodes, new node support poles, or related ground equipment, or any portion of the nodes, poles, or equipment, to minimize the impact to the aesthetics in a historic district or on a design district's decorative poles.

(b) This section may not be construed to limit a municipality's authority to enforce historic preservation zoning regulations consistent with the preservation of local zoning authority under 47 U.S.C. Section 332(c)(7), the requirements for facility modifications under 47 U.S.C. Section 1455(a), or the National Historic Preservation Act of 1966 (54 U.S.C. Section 300101 et seq.), and the regulations adopted to implement those laws.
