The San Antonio River Improvement Project was a multi-phase flood control, amenities, restoration and recreational improvement project funded by the San Antonio River Authority, Bexar County, City of San Antonio and the U.S. Army Corps of Engineers.

Mission Reach was the final 8-mile section of river improvements, extending from Lone Star Boulevard south of downtown San Antonio to just south of Interstate Highway 410. This was the least-developed section of the project and included many new trail amenities and connections to the historic San Antonio missions.

The other project priorities were ecosystem restoration and flood control improvements. Key project elements included realigning the existing channel, establishing a pilot channel, incorporating new trail features (more than 15 miles), adding rock riffle structures, creating 13 acres of embayments, adding tributary mouths, establishing 113 acres of aquatic habitat features along the channel, modifying existing storm drain outfalls, collecting adjacent overland flow to prevent erosion, and modification of existing dam structures. Halff’s scope also included preparation of stream bank stability alternatives to help control the effects of erosion.

Halff provided construction administration support for all phases including observation, submittal reviews and answering contractor requests for information (RFIs).
