City of Austin Performance Report 2015-16

 Number of Linear Feet of Stream Channel Repairs Designed 


Measure Description
The Stream Restoration program’s objective is to create a stable stream system that decreases property loss from erosion and increases the beneficial uses of the City’s waterways. The program performs in-house engineering design and sponsors design of Capital Improvements Program (CIP) projects to alleviate adverse impacts of erosion in Austin’s waterways (creeks). Typical projects include reconstruction of drainage channels, streambank stabilization, and slope restoration/revegetation. This performance measure represents the length of stream channel for which project designs are completed in a fiscal year. The designed projects are constructed by the Field Operations Division or CIP contractors depending on the size and complexity of the project.
Calculation Method
The calculation method is based on the distance, or linear feet, along the stream for which construction plans are developed. This distance is measured on scaled engineering drawings along the centerline of channel for the length of the project.
FY 2015-16 Results
The FY 2015-16 goal for this measure was 4,000 linear feet. The Department was within 2.25% of the goal with 3,910 linear feet of repairs designed.
Assessment of Results
Since FY 2012-13, the goal of the Stream Restoration Program has been to develop engineering designs to repair and restore 4,000 linear feet of stream channel annually. As aforementioned, there was 3,910 feet of repairs designed in FY 2015-16. These stream channel repair designs are completed with a combination of in-house resources and design consultants under contract. The actual output depends on many factors, including the complexity of individual projects and unforeseen demands on staff time, such as flood responses during extreme weather events. The output was reduced in FY 2013-14 and FY 2014-15 due to a reallocation of staff to support the implementation of the Waller Creek District Masterplan. In FY 2015-16, staff was replaced with a new position, and the capacity to complete engineering designs was restored.
Next Steps
The Stream Restoration program not only designs stream channel repairs, it also oversees construction and initial maintenance of channel repairs. In FY 2015-16, 7,202 linear feet of streambank stabilization was completed. The Department will continue to design and perform repairs to the city’s stream system in order to reduce erosion of the waterways.
