Memorandum To: Boards and Commissions From: Greg Meszaros, Director, Austin Water Date: May 4, 2021 Subject: Board and Commission and Citizen Review of new Growth-related Capital Improvement Projects in Drinking Water Protection Zone The Austin City Council approved an amendment to Austin Water’s (AW) Financial Policy No. 8 to provide for enhanced Board and Commission and citizen reviews of AW’s new growth-related capital improvement projects (CIP) located in the Drinking Water Protection Zone (DWPZ). This ordinance (No. 20130117-017) took effect on January 28, 2013 and as part of the 2021 annual budget process, AW is presenting the new growth-related projects to Boards and Commissions as set forth in the ordinance. The revised 2013 Financial Policy No. 8 reads as follows: Capital improvement projects for new water and wastewater treatment plants, capital expansions, and growth-related projects that are located in the Drinking Water Protection Zone (DWPZ) will be identified and submitted, as part of the annual budget process, to the following Boards and Commissions: Water and Wastewater Commission, Resource Management Commission, Environmental Board, Planning Commission, and the Zoning and Platting Commission. These Boards and Commissions will review growth-related DWPZ capital projects spending plans, obtain Board and Commission and citizen input, review consistency with Imagine Austin Comprehensive Plan, review effect on growth within the DWPZ, and make recommendations on project approval for inclusion in Austin Water Utility’s 5-year capital spending plans. This summer, AW representatives will be distributing a brief report to the Commissions on the CIP projects located in the DWPZ related to the financial policy.

Austin Water’s FY22-26 CIP Plan includes projects located across the Austin metropolitan area, including the Drinking Water Protection Zone (DWPZ). In compliance with Austin Water’s Financial Policy No. 8, the capital improvement projects for new water and wastewater treatment plants, capital expansions, and growth related projects that are located in the DWPZ are presented below for consideration by City of Austin Boards and Commissions. These projects represent improvements required to meet Austin Water standards for operability and customer service. While additional capacity may be added in accordance with current design standards, the intent of these projects is to meet the demands of existing or agreed upon future customers rather than promoting additional growth. A map showing specific project locations is provided along with additional project information in the appendix. Table 1.
