To: From: Date: Subject: MEMORANDUM Environmental Commission, Resource Management Commission, and Water and Wastewater Commission Shay Ralls Roalson, P.E., Austin Water Director May 28, 2026 Board and Commission Review of Capital Improvement Projects in the Drinking Water Protection Zone The purpose of this memorandum is to provide a report of Capital Improvement Projects (CIP) located within the City’s Drinking Water Protection Zone (DWPZ), in accordance with Austin Water’s Financial Policy No. 8. The DWPZ designation and the associated financial policy, adopted by City Council, are included in the Appendix and outline the requirements for identifying, reviewing, and obtaining Board and Commission input on capital projects within western Austin and Travis County. The DWPZ is subject to development regulations to protect water quality and contains critical water resources that support both the environment and the community. Together, these policies establish the process through which capital projects in the DWPZ are submitted as part of the annual budget process as part of Austin Water’s comprehensive five-year capital improvement plan. The Fiscal Year 27–31 CIP includes projects located throughout the Austin metropolitan area, including the DWPZ. These projects are essential improvements to maintain and enhance Austin Water’s services and operational standards. Austin Water has a robust and comprehensive asset management and capital planning program, in which condition, capacity, and level of service are reviewed annually to validate these investments in resiliency, preparedness, and proactive infrastructure management. The CIP projects in the DWPZ are shown in the attached CIP Subproject Supplemental Information Summary and Map. Should you have any questions, please contact Randi Jenkins, Deputy Director of Technical Services of Austin Water at randi.jenkins@austintexas.gov or 512-972-0133.
