Coastal Water & Natural Resources
Waterfront developers, municipalities, and others turn to Geosyntec for rigorous assessment and modeling services that support successful and resilient waterfront projects. Our coastal water resources professionals have served as the lead consultants on hundreds of projects. Additionally, we have delivered numerous services through our waterfront and coastal business groups.

Practice Specifics
Clients recognize that we are at the forefront of policy analysis, regulatory compliance, and technology that promotes sustainable water resources management and ecosystem restoration. With extensive experience in this field, we help local governments develop and negotiate long-term control plans for combined sewer overflows, National Pollutant Discharge Elimination System (NPDES) permits, and consent orders. We also comment on Clean Water Act issues at the state and national levels, including developing new recreational use criteria for water bodies across the country and for the US Environmental Protection Agency’s new framework for integrated planning for wastewater and stormwater.

We employ technical experts in fields including geomorphology, ecology, biology, statistics, construction management, computer science, and engineering. Working together, we develop effective studies and solutions for a variety of water-related environmental or developmental issues, including dredging and sediment management, sand replenishment, beach nourishment, and beach preservation.
Our practitioners integrate a consideration of coastal resilience to help clients prepare for hazards, adapt to changing conditions, and recover from severe weather events. In this way, we support them as they create enduring spaces that meet their business goals and enrich the lives of visitors, residents, and workers.
