Project Name: Waller Creek-Reilly Pond

Project Location: Austin, Travis County, Texas

Project Type: Stream Restoration – Habitat and Vegetation

Owner: City of Austin

Two existing flood detention ponds, the Reilly Pond and the Austin Independent School District pond, were proposed for modification to increase capacity in order to attenuate flood flows within the upper Waller Creek urban watershed. In support of this project, Hicks & Company provided environmental services to identify potential environmental constraints associated with the modifications, including delineation of jurisdictional waters (including wetlands) subject to federal regulation under Section 404 of the Clean Water Act and development of riparian restoration plan to remove invasive giant cane and restore native trees, shrubs, grasses, and forbs along the riparian corridor. Deliverables included a technical report summarizing the results of the environmental constraints evaluation, a riparian corridor vegetation restoration plan, and an associated irrigation plan. Required agency coordination was conducted to ensure state and federal regulatory compliance for natural and cultural resources. This included consultation with the Texas Parks and Wildlife Department, Texas Historical Commission, and preparation of a Pre-construction Notification (PCN) for a Nationwide Permit 43, Stormwater Management Facilities, for submittal to the U.S. Army Corps of Engineers.
