At SEH, we’re helping clients improve water quality while balancing complex stormwater needs.

Today’s stormwater management projects are more complex than ever. There is need to balance a multitude of requirements including water quantity, water quality, recreational and aesthetic values and economic considerations. Our approach is to listen to our clients and design complete multi-objective stormwater solutions that fulfill all your requirements.

We are deeply familiar with NPDES Permit requirements, including the storm water program for Municipal Separate Storm Sewer Systems (MS4) and Best Management Practices (BMP) design. We also design Storm Water Pollution Prevention Plans (SWPPP) and perform construction inspection for environmental compliance.
