Borough Engineer Andy Hippol delivered a comprehensive presentation on the borough’s stormwater management challenges. Over the past two decades, New Jersey has faced storms with nearly double the intensity compared to previous years, leading to immediate flooding due to outdated drainage systems. The primary drainage arteries for Tenafly, the Overpeck and Tenafly Creeks, have become obstructed over time by sediment, vegetation, and debris, intensifying flooding issues.

The secured $1.6 million federal grant will fund stormwater management projects, starting with a detailed mapping of the stormwater drainage system. This mapping will gather crucial data on pipe sizes, elevations, and discharge points. Hippol emphasized the importance of public dialogue, encouraging residents to share their flooding experiences and inquiries, as residents’ firsthand knowledge is invaluable to the borough’s efforts.

A systematic approach to stormwater management was emphasized, with a timeline indicating that the next 120 days would focus on mapping. This would be followed by significant planning and evaluation over the next year. Solutions are projected for implementation in 2026, pending federal approval. Concerns were raised about the final destination of water flow, specifically Overpeck Creek leading to New York Bay and TAC Hill flowing north to Cresskill. The potential for cooperation with agencies managing the Oradell Reservoir was also discussed.

The meeting also addressed the equipment and methods for the cleanup process, involving both manpower and machinery. Crews will use chainsaws and manual labor alongside machines positioned on the banks to extract debris. Work within the stream will generally require consent from property owners along the banks, as the borough owns minimal land in those areas. Concerns about property damage during cleanup, particularly landscaping and fences, were assured to be addressed as part of the project.

Residents voiced frustrations about the culvert size contributing to water retention on their properties. Criticisms were directed at broader planning practices and overdevelopment in the town and neighboring municipalities, with calls for immediate federal involvement and a moratorium on new building projects until comprehensive solutions are established.

The use of permeable asphalt was proposed as a potential solution for absorbing excess runoff. However, the challenges of using porous asphalt in Tenafly, due to significant debris runoff, were noted. Rain gardens were suggested as a beneficial community initiative to enhance stormwater management. Collaboration among towns was emphasized, with Tenafly’s involvement in pursuing grants recognized positively during applications.

Neil Ax, a newer resident, inquired about the mapping of streams included in the grant, confirming that the entire stream would be mapped. He also raised concerns about debris, specifically large pipes contributing to runoff. The town is seeking additional grants to address the shortfall in funding for storm drain improvements.

Gina Dinardo shared her experience with flood recovery efforts in Berkeley Township. The conversation underscored the need for regional cooperation and resource acquisition to address persistent flooding challenges.

Concerns about FEMA funding and local flood management were highlighted, noting the complexities of obtaining financial assistance for homeowners. A resident, Bruce Tang, questioned the last time the brook was cleaned, claiming it was about 40 years ago. Responsibilities of homeowners regarding trees falling into streams on their properties were clarified, with the town assisting broader cleanup efforts through grant funding.

Inquiries about the Army Corps of Engineers’ involvement were addressed, clarifying that federal authorization is required for their intervention. Proactive measures and community engagement in flood management discussions were emphasized.

Stephanie, a resident, raised concerns about communication regarding flood management initiatives. She also inquired about planting vegetation near stream banks to alleviate flooding.

Severe flooding at the intersection of Trafalgar and Berkeley was discussed, with residents expressing frustrations about the response from the Department of Public Works. Carol Hornline, a licensed professional engineer, detailed specific flooding issues experienced by property owner Judy Lepson during storm events. She proposed more inlets to manage stormwater effectively and raised concerns about the height of curbs and debris from a neighbor’s construction project.

The council discussed the regulatory framework surrounding property development near streams and the need for surveys to address flooding issues. Residents were encouraged to continue voicing their concerns, with assurances of ongoing communication and commitment to resolving flooding challenges. The meeting concluded with a call for motions to adjourn.
