During the Lago Vista City Council meeting on June 26, 2025, significant concerns were raised regarding the city's water and wastewater master plan. The discussion, initiated by council member Dave Stewart, highlighted critical assumptions and potential flaws in the current planning documents.

Stewart emphasized the need for a technical review of the master plan, particularly pointing out discrepancies in water usage calculations. He noted that the wrong calculator was used for determining water needs, which could lead to inadequate infrastructure to support future growth. Specifically, he mentioned that the calculations indicated a capacity of only 12,000 gallons for a tank, which would not suffice for the projected number of houses.

The council also discussed the necessity of collaboration with developers, suggesting that Wind Ranch and Gross Close should contribute to the costs of off-site storage solutions. Stewart proposed that these developers should be responsible for a portion of the expenses related to a new water tank, which is estimated to cost $4 million.

Additionally, concerns were raised about the planning of new water lines, with suggestions to optimize the layout to avoid unnecessary road disruptions. The council acknowledged the importance of verifying the information presented by Stewart and agreed that city staff should conduct a thorough review of the master plan to address these issues.

The meeting underscored the urgency of ensuring that Lago Vista's water infrastructure can adequately support its growth, with a clear call for action to reassess and potentially amend the existing master plan. The council's next steps will involve staff verification of the presented concerns and a commitment to revisiting the planning documents to ensure they meet the community's needs.
