LWA stormwater management activities include NPDES permitting assistance, development and implementation of programs and guidance manuals for best management practices (BMPs), assessing stormwater quality monitoring data for regulatory compliance, establishing and conducting stormwater monitoring programs, and developing legal authority to establish stormwater management programs.
In addition, LWA has modeled stormwater discharges with EPA’s SWMM and HSPF numerical models and using multivariate statistical regression, Monte Carlo, and modified “rational method” techniques.
