Micco/Little Hollywood Stormwater Best Management Practice (BMP)

Brevard County wanted to experiment with cost-effective ways to boost removal of nitrogen from stormwater prior to the run-off entering the Indian River Lagoon.

DRMP was responsible for providing final design, permitting and bid/construction assistance for this stormwater retrofit project that involved incorporating innovative stormwater treatment techniques into two existing storm outfalls flowing into the St. Sebastian River.   Improvements at the northern outfall (15-acre sub-basin) consisted of approximately 800-LF of exfiltration trench with a specially-design denitrification wall for enhanced treatment.  Improvements at the southern outfall (37-acre sub-basin) consisted of a second-generation baffle box to capture course materials and an off-line sumped and oversized structure filled with media-filled denitrification canisters. The project design included expert assistance from the Desert Research Institute who also performed monitoring and research on the enhanced removal of nitrogen from the stormwater.

This project will improve water quality for the St. Sebastian River and the Indian River Lagoon.  Additionally, research findings from these two retrofits will be applied to further water quality improvements throughout the Indian River Lagoon.
