Project: Santa Maria Subwatershed Improvement - Construction Project

Description: The proposed project aims to achieve multiple goals by capturing, treating and infiltrating stormwater and dry weather (agricultural) runoff from the Main Street Canal. Utilizing a wood-chip bioreactor as an artificial nitrate sink, a percolation pond for infiltration, and a vortex diversion structure to remove sediment. This project will cost effectively recharge groundwater with 300 acre-feet of captured runoff per year. Proposed project goals that meet the multi-beneficial stormwater resource criteria include groundwater recharge, improved regional water supply reliability, improved water quality, and reduced pollutant loads to the Santa Maria River, a 303-(d) listed receiving water.
