Memorandum To: Boards and Commissions From: Greg Meszaros, Director, Austin Water Date: March 25, 2020 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 Waters (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 2020 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 FY21- 25 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 supporting additional growth. A map showing specific project locations is provided along with additional project information in the appendix.

Area is currently served by a hydro tank. The elevated tank will help increase water storage capacity and improve reliability. Improvements to Lost Creek water distribution system (formerly Lost Creek MUD) to increase system reliability. The project includes design and construction of improvements that may include a roadway expansion from two lane section to a four lane divided roadway, signals, medians, waterlines, bicycle and pedestrian facilities, and driveway reconstruction. Rock Harbour lift station improvements, including rehabilitation work of the wet well, pump replacement, and a drop manhole to slow velocities entering the wet well as identified by the Northwest Area Lift Station Study (3168.058). Increase the firm capacity and address operations and maintenance concerns at the Boulder Lane Lift Station as identified by the Northwest Lift Station Study. Increase the capacity of Travis Country Lift Station to address peak wet weather flows and potential future growth in the area. This station has had overflows during wet weather events due to inadequate pumping capacity. Replace and upsize existing 12-inch gravity line from manhole 114641 to manhole 42304 to increase capacity. The existing line is in poor condition and reaching capacity limitations. The project length is approximately 3,000 linear feet. Install 2,700 linear feet of 30-inch wastewater main in the Bauerle Ranch Park that will cross Slaughter Creek.
