Managing urban stormwater runoff can be tricky. But done right, stormwater systems are a valuable amenity. That has always been a guiding principle for our approach to stormwater management. At Olsson, the solutions we develop deliver multiple benefits to our clients, such as reduced flooding, improved stream health and water quality, recreation and citizen acceptance.

We evaluate the needs of clients and then custom design innovative stormwater solutions that are efficient and cost-effective.

Our stormwater services include watershed master planning, stream restoration, urban stormwater management and system design, water quality management and permitting, hydrologic & hydraulic analyses, floodplain modeling and mapping, and more.
