Stormwater. It’s What we do.

Trading collectively as Stormwater Maintenance & Consulting (SMC), Stormwater Maintenance, LLC (SWM) and Stormwater Consulting, Inc., (SCI) are affiliated firms with a singular focus on stormwater.

SWM performs maintenance, repair, and construction of all types of manmade stormwater and natural stream and wetland systems while SCI is a design and consulting firm.  SMC is an industry leader in the practice of engineering, maintaining, repairing, restoring, and retrofitting existing infrastructure.  We are existing infrastructure specialists.

Our in-house expertise begins with seasoned design knowledge and extends to construction, inspection, maintenance, and life cycle repairs.  This diversification of services gives our clients unusual expertise and extraordinary value.  Very few firms have the technical knowledge and experience in design, construction, and maintenance with in-house resources.

We work with all types of stormwater infrastructure including natural streams, manmade drainage systems, high-hazard dams, large traditional facilities, underground structures, and contemporary micro-scale and vegetative-based techniques.

With two locations in Maryland and one in Virginia, our core markets are in Northern Virginia, Maryland, Delaware, the District of Columbia, and Central/Southeastern Pennsylvania.  For multi-site clients, we can provide services from Virginia to Connecticut.

SWM is a Women Owned Business Enterprise (DBE/WBE) in numerous municipalities.  We welcome the opportunity to be a subconsultant or subcontractor on projects with DBE requirements.
