Hydrology and Watershed Services

Dynamic Engineering is a recognized leader in the industry in hydrology and hydraulics. Our experience with new development and urban redevelopment projects has presented us with the unique opportunity to solve real-world stormwater and flood hazard issues including but not limited to, stormwater collection, conveyance, detention and retention design, establishment of flood hazard regulated areas, development within flood hazard regulated areas, channel restoration and bank stabilization of watercourses, culvert and bridge design, and marine and coastal construction.

Stormwater management and flood hazard issues may result in development constraints and may add significant cost to our client’s project. Therefore an expert approach on these issues is imperative to determining the development yield or the financial viability of your project.

During Hurricane Sandy, we experienced firsthand the damage that may be caused by flooding and storm surge. That is why we maintain several Certified Floodplain Managers on staff. Our decades of professional experience in the modeling of floodplains and floodways, give our clients confidence in potential investments by being well informed.

Dynamic has earned a reputation for developing innovative solutions to stormwater management problems. The days of the big dry detention basin are gone due to the regulations enacted by many local and state governments regarding stormwater quantity, water quality and groundwater recharge requirements.

The expectations placed on real estate developers by federal, state, county and municipal authorities are constantly changing. Dynamic can evaluate, pursue, and procure Stormwater and Flood Hazard Area permits from Federal Emergency Management Agency (FEMA), Army Corps of Engineers, Environmental Protection Agency (EPA), State Department of Environmental Protection agencies, and local jurisdictions to expedite your project.
