Our water resources expertise spans from planning to green infrastructure design, with projects supporting land development and transportation activities, as well as municipal, county, and state-wide watershed planning and management plans. With more than 30 years of experience supporting FEMA's National Flood Insurance Program, we are the go-to firm for riverine and coastal flood hazard analysis and mapping, as well as flood risk assessments.

Dewberry® Water Resources Services

Flood hazard analysis

Using the knowledge we've gained from delivering flood hazard modeling (riverine and coastal), mapping, and additional support services for FEMA's National Flood Insurance Program (NFIP) - which includes producing many of the nation's digital flood insurance rate maps - we help clients develop effective solutions to their flood hazard issues.

Flood risk management

Our flood risk evaluation and management services include support in the design and implementation of risk communication strategies tailored to stakeholders' needs through the development of training workshops, collateral materials, and innovative web- and social media-based communication tools designed to increase awareness and understanding of flood risk.

Stormwater management

Our experts develop cost-effective stormwater management and stormwater pollution prevention plans, as well as perform stormwater infrastructure, outfall mapping, and other related work. From reservoir modeling to power generation, we collaborate with clients to develop best-management practice manuals and low-impact development design standards. Our services include industry-leading modeling, capital improvement planning, financial analysis, and stormwater management systems design.

Water supply and management

We help clients meet the growing challenges of water supply, often serving as municipal engineers for a growing number of communities. Our civil and sanitary engineers, hydrogeologists, and planners are skilled in all phases of environmental planning, design, and construction administration. Our water supply experience includes the design of high-yield groundwater supply wells, surface water reservoirs and dams, and off-line storage impoundments.

Water quality

We work closely with regulating agencies, public purveyors of drinking water, publicly owned wastewater treatment facilities, private industry, and academic institutions to develop and implement sustainable, cost-effective policies and infrastructure designed to maintain the quality of our water resources.
