San Pedro Creek Project Links Past to the Future

The San Antonio River Authority hired HDR as prime consultant for the highly anticipated San Pedro Creek Improvement Project, tasking us to transform the two-mile stretch into a linear creekway complete with art, walking paths and park areas, all while accomplishing the main goal of flood control.

The project improvements will reflect the creek’s place in the city’s cultural history, revitalize natural habitats and water quality, and catalyze economic development — while connecting San Antonio’s past with its future. SPCIC has seen significant public outreach and much coordination with stakeholders, agencies and utilities.

Funding Concerns, Other Challenges

HDR led the design team that provided professional design services, including architectural design services, civil engineering, structural engineering, mechanical, electrical and plumbing engineering, geotechnical engineering, surveying, hydraulic modeling, archaeology, cost estimating, landscape architecture, archival research, and environmental permitting.

A portion of Phase 1 of the $200 million four-phase project was completed by May 2018, in time for San Antonio’s 2018 tricentennial celebration. The second portion of Phase 1 is scheduled to be completed and operational in the second quarter of 2021. Breaking the project into phases helped alleviate some of the funding concerns.

New Hydrologic and Hydraulic Model

We performed a drainage study of the watershed by developing a new hydrologic and hydraulic model of the upper San Pedro Creek. The large downtown storm sewer system and the 28-foot diameter bypass tunnel were all modeled in conjunction with the creek to account for watershed timing and storage in this highly urban watershed.

By deepening and widening the existing channel and replacing more than a half-dozen street bridges, the project will contain the 100-year floodplain within the San Pedro Creek banks. It's also expected to spur a $1.5 billion economic impact, 150 percent increase in new property value and $227 million in tax revenues.
