 Hausman Road 

 Improvements 

 Phase 1 

 (LC-9) 

CP&Y prepared a Preliminary Engineering Report (PER) and Plans, Specifications, and Estimates (PS&E) related to the roadway widening of Hausman Road in Bexar County. As part of the Bexar County Flood Control Bond Program, the scope of the project was to provide un-flooded access on this City of San Antonio classified secondary arterial.

To alleviate the roadway flooding, the project required extensive channel excavation both upstream and downstream of the roadway that required continuous coordination with the United States Army Corps of Engineers (USACE), U.S. Fish and Wildlife Service (USFWS), and the Texas Commission on Environmental Quality (TCEQ).

A USACE NWP 27 permit (Aquatic Habitat Restoration, Establishment, and Enhancement Activities) was recommended for the channel work. CP&Y’s environmental team worked closely with the roadway and drainage engineers to design and implement the channel features necessary for the NWP 27. Because of the continual and close coordination with USACE throughout the design process, the USACE reviewed and approved the NWP 27 with no review comments. Final permitting also included a CLOMR for FEMA and a Stormwater Management Plan for the City of San Antonio.

During detailed design, natural channel design elements were implemented in the flood control portion of the project. These elements included meandering low flow channels, pool/riffle sequences, and in-channel depressions to enhance aquatic habitat. The loss of trees was mitigated by broad replanting efforts. An adjacent detention pond for a subdivision was repurposed as a water quality pond to treat runoff from the new roadway surface. This proposed sand filter sedimentation/filtration pond provides additional capacity for future roadway development along the Hausman Road Corridor. The buyout and subsequent removal of flood-prone structures resulted in an overall reduction of impervious cover for the project, providing additional water quality benefits to the watershed.
