Protecting Your Property from Flood Hazards

This webpage has been developed to help minimize risk within floodplains, and in order to reduce the amount of flood damage sustained during future flood events. Some areas of Woodbridge Township have been historically susceptible to flooding, and as a result it’s important to know how to protect your property from a potential flood event. To learn more about how to protect your home from flooding and low-cost projects you can do yourself, click HERE. Be sure to obtain all necessary permits before construction.

The information found on this webpage should be used as complimentary guidance materials. This webpage is intended to help provide an overview of key information related to flood risk and vulnerability as per, federal, state and local regulations and floodplain mapping. However, this webpage does not create liability on the part of the municipality, or any officer, or employee thereof, for any damage that results from reliance on guidance or determinations made by its use. This webpage can be used to help aid decision-making processes with engineers, ecologists, planners, construction officials, and emergency managers.

Protect Yourself from Flood Hazards

Prepare for a Potential Flood Event

• Familiarize yourself with how to turn-off the electricity and gas to your house.

• Be aware of alternative evacuation routes from your neighborhood.

• Gather supplies that you might need during a flood event, such as: a “go-bag,” battery- powered radio, emergency kit, etc.

• Plan for how you will care for your pets during a potential flood event.

• Create a response plan. Visit www.redcross.org to learn more about developing ways to be better prepared. To learn more about what types of flood hazards impact Woodbridge Township Click HERE.

During and After a Flood Event

• Avoid downed power lines that could pose a serious life-threatening hazard. Report these issues to utility companies immediately.

• Generators should never be operated inside your home or garage.

• Never drive down flooded road ways.

• The Department of Homeland Security has developed a checklist designed to help you properly prepare and recover from a potential evacuation.

Build Responsibly in Flood Hazard Areas

If you are in the market to potentially purchase property, you should examine any possibility of a flood hazard BEFORE YOU BUY & BEFORE YOU BUILDand the need to have flood insurance to protect yourselves and your property. Flood-proofing techniques vary in size, scale and scope in relation to specific flood hazard conditions. The Homeowner’s Guide to Retrofitting (FEMA P-312) and other helpful resources are available for order and / or download at www.fema.gov/media-library. Some retrofitting alternatives might include elevating the structure, constructing engineered flood-proofing measures, and protecting utilities. Be sure to obtain all necessary permits before construction. Contact the Building Department (732-602-6003) and Division of Engineering (732-602-6057) for help designing and permitting projects.

The Township recognizes The New Jersey State Flood Hazard Area (FHA) Control Act Rules, N.J.A.C. 7:13. Please note that in situations where the base flood elevation (BFE) denotes a more protective delineation on the 2014 Preliminary FIRM, the State of New Jersey is using the information as the basis for statewide floodplain development standards. To learn more about the types of N.J. Flood Hazard Area Permit Authorizations CLICK HERE. To view the Township's Municipal Flood Damage Ordinance, CLICK HERE and view Chapter 22 of the General Ordinance. To view the Township's Open Space Conservation & Resilience Zone Ordinance (OSC/R Zone), CLICK HERE (PDF).

Click HERE to access the Township’s Floodplain Development Permit Application.

A Floodplain Development Permit is a specific authorization designed in order to comply with Federal, State, and local regulations. A Floodplain Development Permit Application is required if the proposed development is located within a regulatory floodplain, riparian zone, or sensitive environmental area as outlined in the Township's Flood Damage Prevention Ordinance. A community official or the Floodplain Administrator may perform inspections throughout the proposed project, as well as when the project is completed to ensure that the development is compliant with the requirements of the local Flood Damage Prevention Ordinance as well as applicable State and Federal regulations.

The Township of Woodbridge recognizes the Department of Environmental Protection’s Inland Flood Protection Rule, which was adopted by the Department on July 17, 2023.


• New Design Flood Elevation (DFE) raises fluvial (non-tidal) flood elevation mapped by FEMA by three (3) feet

• Requires use of future projected precipitation when calculating flood elevations

• Ensures that DEP’s Flood Hazard Area permits conform to NJ Uniform Construction Code standards and meet or exceed minimum FEMA National Flood Insurance Program requirements

• Requires stormwater Best Management Practices (BMPs) to be designed to manage runoff for both today’s storms and future storms

• Removes use of Rational and Modified Rational methods for stormwater calculations

It's Important to Carry Flood Insurance

Federal law requires that a Flood Insurance Policy be obtained as a condition of a federally backed mortgage or loan that is secured by the structure located in an area of special flood hazard, as per the Effective Flood Insurance Rate Map (FIRM) delineation. Although some areas susceptible to flood risk do not require the purchase of flood insurance, it is recommended in order to best minimize financial vulnerability during a potential flood event.

It’s important to carry flood insurance even if you are not federally required to do so. According to FEMA, a structure located in the Special Flood Hazard Area has a 26% annual chance of experiencing a 100-year flood event over the course of a 30 year mortgage. A property not in a Special Flood Hazard Area (SFHA) may be damaged by a flood greater than that predicted on a flood study, such as a FIRM or state delineation. According to FEMA nearly 25% of all National Flood Insurance Program flood insurance claims come from policy holders outside of federally mapped Special Flood Hazard Areas. Learn more about flood insurance policies available through the NFIP, which could offer lower-cost coverage for structures mapped outside the SFHA.

Most homeowner’s insurance policies do not cover flooding. Don’t wait until storm season to obtain a policy. It typically takes approximately 30 days for a flood insurance policy to take effect. To learn more about flood insurance and to find out how to obtain a policy visit: www.FloodSmart.gov.

Know Your Flood Hazard

Woodbridge Township has areas of special flood hazards located in the AE, A, Coastal A, and VE zones. You can locate Special Flood Hazard Areas in your neighborhood by looking at the Flood Insurance Maps at FEMA's Map Service Center or by visiting our FEMA Flood Zones page by clicking HERE. Woodbridge Township contains areas of tidal and fluvial flooding. Never drive down flooded roadways. To view a real-time tide gauge for NOAA's Sandy Hook Station, click HERE.

The Township of Woodbridge participated in updating the Middlesex County Hazard Mitigation Plan. The plan is designed to help identify local weaknesses and assess ways to potentially combat those issues. Thus, the overall outcome of the plan's development to reduce devastating effects of future storm events and other natural hazards.

"Region 2 Coastal Analysis and Mapping" is a great resource to compare the effective and revised FEMA flood hazard data available for properties in the community.

Protecting Our Natural Floodplain

Only rain goes down the storm drain. The ability for storm drain systems to function correctly directly relates to minimizing the flood inundation, potential damage sustained during strong rain events, and the reduction of non-point source pollution into our waterways. Natural habitats are the definition of resilient infrastructure, as they are more readily able to rebound after powerful storm events. In addition to providing flood storage capacity, these areas are havens for safeguarding the existing benefits associated with healthy natural areas, such as filtration of nutrient runoff and biodiversity.
