Princeton Hydro was proud to participate in the New Jersey Association for Floodplain Management (NJAFM) 20th Annual Conference and Exhibition, held this fall in Atlantic City, NJ. Celebrating two decades of collaboration and innovation within the floodplain management community, the conference brought together more than 500 practitioners, researchers, agency staff, and industry leaders from across the Northeast.
As the region’s premier floodplain management event, the NJAFM conference serves as a hub for sharing cutting-edge tools, best practices, and real-world strategies that help communities reduce flood risk, adapt to changing climate conditions, and build long-term resilience. Over the course of two days, participants attended educational sessions, hands-on training, and networking events centered on the theme: “NJAFM at 20 Years: Celebrate the Past, Focus on the Future.”
Princeton Hydro was excited to return as a conference sponsor, exhibitor, and session presenter.
Floodplain management is a multidisciplinary practice that integrates planning, engineering, ecological science, and public policy to reduce flood risk while preserving the natural functions of riverine and coastal systems. At its core, it involves understanding how water moves across a landscape, identifying areas vulnerable to flooding, and implementing measures that protect people, infrastructure, and ecosystems.
Floodplains provide a range of essential functions. Hydrologically, they convey, store, and infiltrate water during storm events, supporting natural flood attenuation, erosion control, and groundwater recharge. Ecologically, they contribute to biodiversity by providing habitat, migration corridors, and spawning areas for fish and wildlife. From a community perspective, well-managed floodplains can offer recreational value, improve water quality, and enhance the aesthetic and economic vitality of local neighborhoods.
Modern floodplain management relies on both structural and non-structural approaches. Structural measures may include engineered solutions such as levees, floodwalls, culvert improvements, or stormwater system upgrades. Non-structural tools often involve land-use planning, flood-resilient building standards, conservation of open space, and community engagement programs that help residents understand risk and adopt best practices.
Princeton Hydro works with municipalities, state agencies, nonprofit organizations, and watershed groups to develop and implement comprehensive floodplain management strategies across the region, emphasizing strategies that balance flood risk reduction with ecological enhancement, ensuring that floodplain management supports both resilient communities and healthy, functioning watersheds.
Pictured above: before and after photos from the Floodplain Restoration and Urban Wetland Creation project in Bloomfield Township, New Jersey. By removing a little over four acres of upland historic fill in this densely developed area and converting it into 4.2 acres of a functioning floodplain wetland, the project restored valuable ecological functions, enhances wetland and riparian zone habitat, and increases flood storage capacity for urban stormwater runoff.
Our team led two workshops at the NJAFM 20th Annual Conference:
Christiana Pollack, CERP, CFM, GISP, Princeton Hydro’s Director of Restoration and Resilience, presented on strategies to address chronic flooding and climate-driven impacts in Eastwick and Tinicum Township, Philadelphia. Her talk highlighted a two-year technical assessment commissioned by The Nature Conservancy in Pennsylvania and the John Heinz National Wildlife Refuge, and led by Princeton Hydro. The project combines integrated field data collection, advanced hydrologic and hydraulic modeling, and rigorous alternatives analysis to evaluate nature-based solutions. These include wetland creation or enhancement, stream and floodplain reconnection, and stormwater management retrofits, with the ultimate goal of restoring natural hydrologic function, reducing flood risk, and strengthening habitat and community resilience.

Elizabeth Treadway of WSP USA and Dr. Clay Emerson, PhD, PE, CFM, Senior Technical Director of Engineering at Princeton Hydro, led a session on the practical, legal, and financial considerations of establishing a stormwater utility, an increasingly vital tool for sustainable infrastructure funding. Participants learned:
The session also addressed common challenges such as aging infrastructure, rapid development, and the growing frequency of severe storm events driven by climate change. Stormwater feasibility studies were highlighted as a key resource for evaluating costs and benefits before moving forward.

Throughout the conference, our team was able to connect with planners, municipal officials, engineers, and local leaders at our exhibitor booth. These conversations offered valuable opportunities to discuss project experiences, share resources, and learn from others working to advance resilience across New Jersey.
Princeton Hydro is proud to be part of this community and remains committed to advancing science-based, equitable, and sustainable approaches to reducing flood risk. We look forward to continuing our partnership with NJAFM and supporting clients and communities in building a safer, more resilient future.
