1118 Uhl Road in Glenn Heights
GHF Civic Reference
A continuing public record of the proposed data center at 1118 Uhl Road — including the zoning history, Chapter 380 economic development agreement, infrastructure commitments, changing development plans, public questions and Glenn Heights Future reporting.
The property is zoned for a data center and electrical substation. Although the original development concept contemplated a larger multi-building campus, AMF Mission Critical said in July 2026 that its current Phase 1 plan is one building. A detailed site plan must still go through the city's development review process.
The Project
Key facts drawn from the city's zoning records, economic development agreement and subsequent public discussions.
1118 Uhl Road in Glenn Heights
Party to the Chapter 380 economic development agreement
Minimum capital investment required under the 380 agreement
Minimum approximate building size stated in the agreement
Economic development grant paid under conditions in the agreement
Cash contribution designated for improvements to Heritage Park
Public Record
The data center has developed over multiple years through zoning, economic development agreements and continuing public discussion.
According to the public project history later presented by city officials, staff discussions surrounding the development began in early 2024.
The proposed Planned Development moved through the city's Planning and Zoning process as the developer sought permission for a data center campus and related electrical infrastructure.
Major Action
The City Council considered the second reading of the zoning ordinance establishing PD-30 with Industrial base zoning for a data center and electrical substation on approximately 140 acres. Council also considered Resolution R-32-24 authorizing the Chapter 380 economic development agreement with AMF Mission Critical.
Residents raised questions about land use, financial benefits, infrastructure, water and quality-of-life impacts during a community discussion about the already-approved zoning.

Read GHF coverage →Plan Changes
During the City Council discussion, AMF Mission Critical said it had shifted from the original larger Phase 1 concept to one initial building, citing electrical availability, market conditions and community reaction.

The economic development agreement establishes obligations that must be met before and during payment of the city's economic development grant.
The agreement is more specific than the project's concept drawings. It defines what Phase 1 must include and establishes financial, infrastructure and public-improvement conditions.
Read the Chapter 380 Agreement →The agreement defines the required Capital Investment as at least $250 million in the property and Phase 1 improvements.
The Phase 1 building is defined as an initial data center building containing not less than approximately 50,000 square feet.
The agreement establishes a total not-to-exceed grant amount of $15 million, subject to the agreement's conditions.
Annual grant installments are calculated using 50% of the qualifying ad valorem taxes assessed and collected by the city, subject to the agreement's requirements and overall cap.
The company must make a $1 million cash contribution designated for improvements to Heritage Park before receiving the first grant.
The company must complete specified improvements along South Uhl Road from Bear Creek Road toward Heartland Drive. The agreement lists an estimated $15 million cost and places overruns on the company.
Phase 1 includes a 10-foot shared-use pedestrian and bicycle trail along portions of the property's southern and western boundaries.
The agreement allows a temporary construction-access corridor through Heritage Park intended to reduce construction traffic using South Uhl Road.
Although the development concept depicts additional improvements, the Chapter 380 agreement expressly states that it does not require construction of vertical improvements beyond the Phase 1 building. Additional development could occur, but it is not guaranteed by the agreement itself.
What Residents Are Asking
Some questions have been addressed publicly. Others remain dependent on detailed engineering, site-plan or operational information.
The developer has said the proposed facility would use a closed-loop cooling system. GHF continues to distinguish that statement from independently verified consumption data.
The developer has said electrical availability contributed to the decision to begin with a smaller Phase 1. Final electrical demand remains an important part of understanding the project's full scale.
Data centers can contain cooling equipment, electrical equipment and backup generators. GHF's Richardson reporting found mixed experiences among nearby residents, including repeated noise concerns.
The project could substantially increase the property's taxable value, while the Chapter 380 agreement also returns a portion of eligible city property-tax collections through the grant structure. Actual revenue will depend on completed investment, appraised value and other factors.
AMF Mission Critical currently says Phase 1 will begin with one building. The zoning framework can accommodate additional development, but the 380 agreement does not require every building shown on the original concept plan to be constructed.
The agreement includes Uhl Road improvements, a public trail and a $1 million Heritage Park contribution. Larger questions remain about electrical and other infrastructure required at full buildout.
