Description

This project involves the repair of five existing A-weir cross-vane grade control structures along the Santa Fe River between Camino Rio and Camino de la Vuelta. The work includes reconstruction of failed structures as grouted boulder ramps with integrated stilling basins, cutoff sills, and subsurface drain tiles to mitigate erosion and seepage risks. Post-construction, all disturbed areas will be revegetated to restore natural conditions and enhance riparian zones. The design aims to re-establish channel grade, improve floodplain connectivity, and promote long-term stability while minimizing environmental disturbance. The project builds on prior efforts following severe weather damage in 2018.
