Flood Mitigation Information

Lambertville faces dual threats from floods — localized flash floods caused by heavy rains, and the rising of the Delaware River due to higher water volumes generated upriver. High water velocities, clogging of storm drains, stream bank erosion, and even stream bank failure have all been by-products of flooding. Flooding also can occur when heavy rainfalls collect on the hills and rush into our neighborhoods, as was most recently evidenced during Tropical Storm Irene in 2011.

Lambertville is vulnerable to direct flooding from the rising on the Delaware River and back-flooding local tributaries. Major floods on the Delaware River impacting Lambertville occurred historically in October 1903, March 1936, and August 1955 (record flood), and then most recently in September 2004, April 2005, and June 2006. Heavy rains feeding into the Alexauken, Ely, and Swan creeks can create immediate, localized flash floods.

The City of Lambertville keeps Elevation Certificates on file for some buildings within the floodplain. Contact the Construction Office at (609) 397-0803 or [email protected] for more information on your local flood hazard.

Floodplain maps and other information regarding local flood hazards and flood protection measures can also be found at the Lambertville Free and Public Library, 6 Lily Street. Ask the librarian for help in determining your location on Google Earth with the National Flood Hazard Layer. 

Additional Information

Flood Safety

Flood Safety

Flooding is a natural and inevitable process, but simple actions can reduce the safety risk for yourself and the community.

  • Do not drive through a flooded area – A significant number of flood related fatalities occur from individuals attempting to drive in a flooded area.

  • Do not walk through flowing water – Flood waters may have deceiving undercurrents.  Six inches of water may knock you off your feet.  Low areas may be concealed by floodwater.

  • Stay away from power lines and electrical wires – Electrocution is the 2nd leading cause of death during floods.  Turn off power at the service box prior to flooding if possible.  Water can carry electric current.

  • Be alert to gas leaks – If you smell gas, report it immediately to your gas company and call 9-1-1 for assistance from the Lambertville Fire Department.

  • Keep children away from the flood water, ditches, culverts and storm drains – Flood waters travel at a velocity greater than children may be able to see or understand.

  • Clean everything that has been wet – Flood waters can contain raw waste, chemicals, bacteria.  It is important to disinfect all salvageable possessions that were inundated with floodwaters.

  • Look out for animals – Flood waters can displace habitat and many animals may take refuge in your home, car, or other structures.

  • Do not use gas engines, such as generators, or charcoal fires indoors during power outages – Carbon monoxide gas exhaust can pose serious health hazards and an indoor open fire can ignite many household materials.

Local Flooding Hazards

Alexauken Creek

As with Swan Creek, the Alexauken Creek floodplain back-flows from the Delaware River. The areas that is impacted includes the north most end of North Union Street and just north of and adjacent to Cherry Street.
