6 yrscommunity opposition (MUD filed March 2020)
Conditions before construction include: the MUD must become a legal entity; Parker and TxDOT must approve the entrance; groundwater permits (North Texas Groundwater Conservation District and TCEQ) must be obtained; the wastewater legal case must be resolved; the flood study must be approved; and other technical approvals must be completed. The plat still shows only one point of access.
Parker reports agreement in principle on a majority of its Key Issues and has floated a 170-home framework with City water and sewer — but has executed no documents. Its March 2026 conditional approval of the preliminary plat for the FM 2551 connection was ministerial under Texas law, with stipulations, and is not an endorsement of the development or the single entrance.
The MUD creation petition, first filed in March 2020, remains in contested proceedings with 60+ parties. Residents and the City of Parker hold party status. Without a MUD, the financing and sewer-plant model collapses.
TCEQ permitted a proposed on-site wastewater treatment plant (WWTP) to discharge up to 200,000 gallons/day of treated effluent into Maxwell Creek. That permit is under challenge in Travis County District Court.
The County accepts a single access point only by treating the plat as all single-family with sprinklers in every home. The Fire Marshal confirmed buildings with four or more dwelling units would trigger a two-entrance requirement — and the developer’s own traffic study evaluated 309 multifamily units in 11 buildings. Our position: 600+ homes need two entrances regardless of sprinklers.
Flood study approval remains an unmet plat condition. Runoff toward Maxwell Creek, Dublin Creek, Cottonwood Creek, and downstream properties has not been resolved by an approved drainage/flood study based on the County Final Plat. The site drains to the FEMA floodplain of Maxwell Creek and on toward Lake Ray Hubbard, with approximately one-third of the drainage flowing toward Dublin Creek.
Water would come from proposed groundwater wells. The developer’s groundwater availability certification is under review by the North Texas Groundwater Conservation District, permits from that district and TCEQ are required before construction, and water/CCN service questions remain open.
A TxDOT driveway permit is an unmet condition of the County’s plat approval. State-road access and traffic impacts remain under review.
The Gregory Lane lawsuit was nonsuited in April 2026 — but the underlying question stands: County Engineering has no records of Gregory Lane as a county road, and a legal review found no recorded documentation that it was ever formally dedicated and accepted as a public road. Easements and right-of-way are not the same. Eminent-domain exposure for nearby private-property owners remains.
| Source / Version | Development description | Why it matters |
|---|---|---|
| Original / TCEQ MUD materials | Approximately 666 homes / units tied to the proposed Collin County MUD No. 7 and wastewater treatment plant (WWTP) | This is the basis of the pending TCEQ contested case history, now with 60+ parties. |
| Traffic Impact Analysis reports | 693 total units: 384 single-family homes and 309 multifamily units in 11 buildings | The traffic analysis appears to evaluate a higher-density plan than other versions presented to the public or local governments. It also raises questions about access, emergency response, fire-code classification, and whether later plans materially changed. |
| Parker negotiation update | Parker publicly referenced a possible path toward 170 detached single-family homes if major issues were resolved | This is not the same as the higher-density TIA or County final plat materials and should not be confused with final approval. |
| Collin County final plat materials | 624 residential lots on approximately 100 acres, with MUD-owned roads and utilities | This is the version conditionally approved by Collin County, but significant issues remain regarding Parker approval, TxDOT access, water/CCN, wastewater, groundwater, flood study, emergency access, and traffic safety. |
