Services
Floodplain Studies
Our floodplain studies combine HEC-RAS modeling and FEMA guidelines to delineate flood hazard zones and develop mitigation strategies. We provide DFIRM maps, floodway analyses, and regulatory permitting for riverine systems across multiple states. Our expertise includes unsteady flow modeling and community coordination for National Flood Insurance Program compliance.
Stormwater Engineering
We design comprehensive stormwater systems including detention ponds, culverts, and channel improvements. Our approach integrates hydraulic modeling with civil infrastructure planning to address both localized and regional flood control needs. Projects often include water quality enhancements and multi-jurisdictional permitting for municipal and private clients.
Stream Restoration
Our stream restoration projects combine geomorphic assessments with hydraulic engineering to stabilize channels and enhance ecosystems. We develop process-based solutions that balance infrastructure protection with natural channel function, including sediment transport analysis and aquatic habitat improvements across urban and rural environments.
Irrigation Systems
We provide end-to-end irrigation engineering services from system inventory to automation design. Our expertise includes canal rehabilitation, telemetry control systems, and water rights analysis for agricultural clients. We specialize in balancing efficiency improvements with environmental considerations in both large district systems and individual farm operations.
Levee Design
Our levee engineering services include design, accreditation, and recertification following FEMA and USACE standards. We conduct freeboard analysis, pipe penetration evaluations, and breach modeling to ensure flood protection systems meet regulatory requirements while protecting residential and commercial properties in high-risk areas.
