City of Austin Performance Report 2014-15

Number of Structures/Roadways With Increased Flood Protection–Project Completed

Measure Description
This performance measure represents the Department’s efforts to reduce flooding conditions in order to protect lives and property. Improvement projects are planned, designed, and constructed to reduce creek and localized flood hazards to houses, commercial buildings, and roadways.
Calculation Method
To calculate this measure, a count is taken annually of the number of structures and roadway crossings with reduced risk of creek or localized flooding due to completed flood hazard improvement projects.
FY 2014-15 Results
The FY 2014-15 goal for this measure was 9 structures/roadways with increased flood protection, and the actual number of structures/roadways with increased protection was 37.
Assessment of Results
A total of 37 structures/roadways had a reduced risk of flooding due to completed flood hazard mitigation projects, exceeding the goal of 9 structures/roadways with reduced risk of flooding. The FY 2014-15 goal was significantly lower than in previous years due to the anticipation of a limited availability of funding to move projects into construction. The FY 2015-16 target has been increased to 63 structures. Completed projects include: a project on Woodhue Drive that helped protect 4 structures, a project at the Park at Riverside development that provided increased flood protection to 25 structures, improvements to the Reilly Pond system to lower the risk of the pond system overtopping at low spots along the embankment, and a localized flood hazard mitigation project that added storm systems on Gaston Avenue and 30th/Oakmont to an Austin Water capital project in the Pemberton Heights neighborhood, which increased flood hazard protection for 7 structures/roadways.

Next Steps
The Watershed Protection Department continues to update its Master Plan problem-scoring for the Creek Flood Hazard Mitigation Program as floodplain models are updated and made significant overhaul to the process in FY 2014-15 to identify projects with high-risk structures that are not in the vicinity of a large number of other at-risk structures. There are also ongoing efforts to complete a comprehensive assessment of storm drain infrastructure needs City wide with the use of two dimensional modeling and collaboration with the Field Operations Division’s field investigation and assessment techniques. The Localized Flood Hazard Mitigation Program currently relies on reported flooding and complaints to prioritize capital improvement projects. The comprehensive assessment will enable staff to more objectively evaluate the capacity of the existing system and prioritize improvements needs using predictive modeling.
