Swale Grading Program
This program performs swale restoration to alleviate flooding issues from developed properties, and re-establishes grades on an as-needed basis; thus allowing the proper movement and treatment of storm water with infiltration as mandated by National Pollutant Discharge Elimination System (N.P.D.E.S.) permit. Over time swales fill with silt, and the flowline doesn’t function as originally constructed. Most times the swales just need regrading vs. more corrective adjustments such as driveway replacement, installation of slot drains, adding a catch basin, etc.
