The design of sustainable management systems is evolving. Engineers and planners cannot manage stormwater using practices of the past. New and future rules and practicality will simply not allow it. Just like detention basins, designs that incorporate infiltration, water quality treatment, and stream bank protection are changing dramatically over the next several years as we learn more about design and maintenance. Consequently, engineering and planning firms that understand and are involved with research on these new practices will have a strategic advantage over those firms that do not. Our Partners Members, and Friends, from both the public and private sector, understand this reality and have joined us in our mission to advance the practice of comprehensive stormwater management.
