In an effort to provide more reliable and effective communications with citizens, Frelinghuysen Township has implemented Swiftreach Networks, Inc. as our emergency notification provider.

Swift911™ is a system designed to make phone calls to specific people or areas in the event of an emergency or for sharing important information. Frelinghuysen Office of Emergency Management and other departments will use this system to notify citizens by phone of information regarding you or your property. The system can make thousands of calls in a minute to convey vital information. These messages may include information on floods, fires, water emergencies, road closures, missing persons, evacuation orders, and weather emergencies.

The Swiftreach Network Data has been provided by a third party data provider and only includes listed phone numbers in Frelinghuysen Township. It is important for residents and business owners to provide contact information such as unlisted, unpublished or cell phone numbers. Accurate numbers in the database help to ensure emergency information will be passed on to everyone in a timely manner.

Please note: This website it is not monitored on a 24/7 basis and if you are experiencing a true emergency you should dial 911.

November 20, 2018 - Please welcome Stacy Galante as the new secretary to the Environmental and Historical Committees!

October 25, 2018 - On October 25, 2018 a person identifying themselves as a JCP&L employee attempted to gain access to a resident’s home. The resident called JCP&L and was informed that the person was not a JCP&L employee. The resident informed the State Police. The incident took place in the Johnsonburg area. The Township once again asks all residents to be careful and if confronted with a similar situation not to let such persons in their home without confirming their identity through the public utility, and to notify the State Police if necessary.

October 24, 2018 - The free rabies clinic will be on December 8th from 10 am to 11 am at the Frelinghuysen town garage located at 219 Main Street. For both cats and dogs. Any questions call the town hall at 908-852-4121.

October 2, 2018 - Over the last month there have been several thefts from vehicles and residences throughout the Township. While most recently thefts occurred on Saddle Ridge Road, Homestead Drive and Greendell Road, there have also been reported incidents or attempts on Main Street, Lincoln Laurel Road, and Golden Chain Road. We ask that all residents of Frelinghuysen be aware of suspicious activity, unfamiliar persons or vehicles, and report same immediately to the State Police. Likewise, if you have witnessed any suspicious activity which may be linked to these events, please report same immediately to the State Police. We also ask that residents take care to lock their vehicles, residences and outbuildings, even when you are at home.

August 28, 2018 - The Spotted Lanternfly, Lycorma delicatula is a new pest to the United States. This invasive planthopper, initially discovered in in Berks County, Pennsylvania in 2014 is native to Southeast Asia and poses a threat to forests, ornamental trees, orchards, vegetables, grapes, hops and other agricultural commodities. Since its initial discovery in Pennsylvania it has spread to infest portions of 13 counties of that state, recently it has been discovered in New Jersey in Warren, Hunterdon and Mercer Counties. The New Jersey Department of Agriculture has recently enacted a state quarantine in these counties to restrict the movement of this insect to un-infested areas of the state. All other life stages of this insect, from nymphs to adults can fly, hop, or drop right into or onto vehicles – meaning that vehicles and equipment can easily and quickly help it spread. Read the details here.

April 5, 2018 - The New Jersey Board of Public Utilities has a "Clean Energy" incentive program for New Jersey residents, businesses and local municipalities. (read the flier here)
