Water Resources

Protecting people, infrastructure, and property with sensible and cost-effective flood control systems; building resilient stormwater infrastructure; and preservation and enhancement of the water quality of our lakes, rivers, and streams are the guiding principles of our approach to water resources engineering.

From small-scale drainage studies to large and detailed stormwater master plans, hydrologic and hydraulic studies, design, permitting, and assistance with grant funding, our diverse team of water resource professionals can provide solutions for your project.

Our award-winning water resource team comprises of certified floodplain managers, planners, scientists, and engineers to provide holistic solutions to our clients’ diverse needs. Our services protect people and property from water damage, prevent degradation of water resources, and restore vital aquatic systems.

Stormwater + Floodplain Management

We have specialized experience in preparing detailed stormwater and watershed master plans, compliance with floodway and floodplain regulations, and design and construction phase services.

Hydrologic and Hydraulic Modeling

Our team is well versed in all facets of Hydrologic and Hydraulic (H&H) modeling including 1D/2D and steady and unsteady state modeling. We have modeled small to large, and rural to urban watersheds including floodway and floodplain analyses utilizing state of the art software accepted by regulatory agencies.

Flood Control Systems

Our designs include award winning flood control systems comprising of storm sewers, pump stations, detention facilities and levee design and certification. We’ve helped communities protect critical infrastructure and public/private property.

Restoration + Enhancement

Our services include field assessments, stream and riparian corridor restoration, bank and shoreline stabilization, natural channel design including custom urban stream solutions, restoration of wetland lakes and ponds, and detention basin retrofits.

Green Infrastructure

Our team has extensive experience in the planning, design and construction phase services of green infrastructure improvements. We have successfully integrated green infrastructure practices with gray infrastructure design as part of an effective flood reduction strategy and water quality improvements.

Highway Drainage

We have worked with local agencies, Counties and State DOT’s to prepare Location Drainage Studies for highway drainage systems and Hydraulic Reports for Bridge and Culvert improvements. We partner with transportation engineers to find low impact solutions to highway drainage including implementing green infrastructure BMP’s.

Permitting + Compliance

Early coordination with permitting agencies ensures a streamlined project and avoids surprises. Our water resource engineers remain current with emerging regulations. We provide permitting assistance with local, state and federal agencies including ACOE and FEMA. We have extensive experience in preparing CLOMR’s/LOMR’s.

Grants + Funding Assistance

We partner with clients to identify sources of funding that meets the need. Strategies may range from tried-and-true sources including local, state and federal grants; state revolving loans; bonds; stormwater utility set up or rate adjustments; and today’s emerging new alternatives, such as public-private partnerships (P3). We have helped clients identify and secure local, state and federal funding for stormwater projects including FEMA HMGP grant funding, CDBG, and EPA 319(h) amongst others.
