The property sits between established neighborhoods served by narrow roads never designed for a high-density development’s daily trips — or for years of heavy construction traffic. A prior draft agreement called Gregory Lane “emergency use only” while opening it to construction traffic for up to 48 months. It was never approved.

Replacing open land with rooftops and pavement increases stormwater runoff. Runoff affects Maxwell Creek, Dublin Creek, and Cottonwood Creek. Upstream and downstream homeowners already flood in heavy rain. Flood study approval remains an unmet plat condition, and the County Final Plat does not resolve these concerns through an approved drainage/flood study. Draft terms that would have frozen City drainage oversight and shifted maintenance to a developer-controlled MUD made this worse, not better.
TCEQ granted a permit allowing an on-site wastewater treatment plant (WWTP) to discharge up to 200,000 gallons per day of treated effluent into Maxwell Creek, which runs through the center of Murphy and drains downstream toward Dublin Creek and Cottonwood Creek. That permit is under challenge in Travis County District Court. Experts retained by the community have testified about risks to the creeks, wildlife, water sources, and nearby neighborhoods, including nuisance odors. Water would come from proposed groundwater wells; the developer’s groundwater availability certification is under review by the North Texas Groundwater Conservation District, and permits from that district and TCEQ are required before construction. Water/CCN service-area questions also remain open. Parker’s alternative framework — City-provided water and sewer with no plant — exists only in principle, with nothing executed.
The concern is not just the number of homes: different public documents describe different versions of the project, with different unit counts, land-use assumptions, access assumptions, and infrastructure impacts. The developer’s own traffic study evaluated 693 units including multifamily, and Parker P&Z declined a proposal in February 2026. Questions posed directly by City Council — including which properties a MUD would use eminent domain powers on — went unanswered in public.
05 · Gregory Lane, private property, and for utilities
The Gregory Lane lawsuit was nonsuited in April 2026, but the underlying record question stands: Collin County Engineering has confirmed it has no records showing Gregory Lane as a county road, and a law-firm review of the deeds, plats, and recorded documents found no legal documentation that Gregory Lane was ever formally dedicated and accepted as a public road. Right-of-way and utility easements exist in portions of the area — but easements do not make a road a publicly dedicated street, and the County’s GIS map is not a legal record of ownership or dedication. Meanwhile, a MUD would retain condemnation powers inside Parker for utilities and drainage protections.

This matter spans the County’s conditional plat approval and its unmet conditions, active Parker–RTG negotiations with nothing executed, TxDOT access review, the still-pending MUD creation case at TCEQ and SOAH, and court review of the granted wastewater treatment plant (WWTP) permit. Residents and the City of Parker hold party status in the contested case, which now includes 60+ parties. Pending lawsuits and protests remain the community’s principal leverage to secure enforceable protections — which is why we have consistently urged that they not be withdrawn prematurely.
