A public hearing for a wastewater permit renewal that would authorize Lennar Homes to discharge up to 300,000 gallons of wastewater per day into Canyon Lake is scheduled for 7 p.m. Tuesday, June 2 at the Hampton Inn Bulverde Texas Hill Country, 499 Singing Oaks, Spring Branch.
Texas Commission on Environmental Quality (TCEQ), the state agency tasked with issuing permits, will host the meeting.
The permit is for a wastewater facility for Canyon Ranch, a 1,500-home development underway on 400 acres northwest of Canyon Lake near the Mystic Shores subdivision in Spring Branch.
The facility would discharge up to 300,000 gallons per day of treated domestic wastewater into an unnamed tributary of Devil’s Hollow, then into Devil’s Hollow, and ultimately into Canyon Lake.
“Community members are raising concerns about water quality, nutrient pollution, impacts to local groundwater resources, downstream flow-and-erosion conditions and the need for stronger permit protections,” said Annalisa Peace, executive director of the Greater Edwards Aquifer Alliance (GEAA).
The nonprofit recently partnered with Mystic Shores Neighbors to contest the permit.
The June 2 hearing includes an informal question-and-answer period followed by a formal comment period.
Residents are encouraged to attend, ask questions, and provide formal comments on the record.
Comal County Precinct 4 Commissioner Jen Crownover advises residents not to get their hopes up, as the hearing is about renewing an existing permit.
“I definitely encourage people to be active and engaged,” she said. “With the TCEQ being what it is, and the county not having a seat at the table, I’m not sure how effective it is, but at least we try.”
In April 2025, commissioners approved plats for a second unit for the development, consisting of about 13 acres, 52 lots, and the right-of-way along FM 306.
By state law, commissioners are required to rubber-stamp subdivisions that comply with all applicable regulations and statutes.
Lennar obtained water contracts and service commitments several years ago and long before Texas Water Company made headlines in March 2025 by temporarily pausing new service commitments for nine other proposed developments in Comal County.
