San Antonio River is the river flowing through San Antonio and the Mission Reach south to the San Antonio Bay system - an urban-to-coastal river with significant recreational development in its San Antonio reach. Active bank erosion, seasonal flooding, and demand for waterfront access create ongoing marine construction needs for residential and commercial properties here.
San Antonio River is the river flowing through San Antonio and the Mission Reach south to the San Antonio Bay system - an urban-to-coastal river with significant recreational development in its San Antonio reach. Construction here must account for seasonal high-water events that scour banks and deposit sediment. Soft alluvial or sandy soils require probing before pile placement, and structures must handle river current and flood-stage flow. Army Corps Section 404 permits apply to any work in or near the channel.

Shore Protect Team provides bank stabilization, retaining wall construction, dock and access installation, and shoreline erosion control along the San Antonio River in Bexar, Wilson, Karnes, Goliad, and Refugio counties from San Antonio through the coastal plain to its discharge into San Antonio Bay. The San Antonio River flows from the springs of San Antonio through the city's iconic River Walk before continuing through the south Texas coastal plain - the upper urban sections are highly engineered while the rural lower river retains a more natural meandering character with active bank erosion at its meander bends.
The San Antonio River in Bexar County is heavily channelized and engineered through the city - the River Walk section and flood control improvements downstream of downtown San Antonio are concrete-lined or riprap-armored channels with limited natural bank erosion. The lower rural San Antonio River in Wilson, Karnes, and Goliad counties returns to a natural meandering character where bank erosion at outside bends is the primary challenge for riverside landowners. Shore Protect Team primarily serves the rural lower river sections where natural channel behavior creates the active bank erosion conditions that benefit from professional bank stabilization.
Bank work along the rural San Antonio River in Wilson, Karnes, Goliad, and Refugio counties requires Corps of Engineers Section 404 permits for fill in jurisdictional waters. The tidal lower San Antonio River near its discharge into San Antonio Bay in Refugio County may also require Texas GLO coastal zone permits. Shore Protect Team identifies the applicable permits for each San Antonio River location based on its position and the waterway's jurisdictional classification.
The lower San Antonio River in the coastal plain counties of Karnes, Goliad, and Refugio flows through clay and sandy loam soils typical of the Gulf Coastal Plain - these cohesive soils resist erosion under normal flow but erode rapidly during the flood events driven by Gulf moisture rain systems affecting south-central Texas. Outside meander bends on the lower San Antonio River can lose 10 to 20 feet of bank during major flood events without protection, making proactive bank stabilization cost-effective for landowners with significant acreage near active meanders.
Send Shore Protect Team your San Antonio River property location and county and photos of your bank and erosion conditions. We assess the erosion rate and permit requirements for your specific river location and provide a preliminary cost estimate.
