2026 ARBOR DAY HERITAGE TREE PLANTING COMMEMORATES USA 250TH 

In honor of Arbor Day, Mayor Jim Kelly and Councilwoman Marilyn Althoff joined the Department of Public Works, the Mendham Borough Shade Tree Commission, and local residents to plant a heritage tree commemorating the USA 250th birthday in the new Mendham Borough Arboretum this past Friday. The Borough would like to extend a big thank you to Tim Foerster of the Shade Tree Commission, Dave from ECOSST, as well as the DPW which makes the Shade Tree Program possible.

The event followed Mayor Kelly’s formal signing of the Arbor Day Proclamation for April 24, 2026, a gesture encouraging all residents to support the environment by planting trees throughout the community.

The Borough of Mendham would like to congratulate Pattie Jones, who is retiring after 27 years with the UPS! Pattie concluded her final route with a special commendation presented by Assemblywoman Aura Dunn, alongside Mayor Jim Kelly and Councilwoman Marilyn Althoff. Click Here to read the full story.

Patriots' Path Improvements Project

Dear Residents,

We would like to inform you of upcoming improvements to Patriots' Path that will enhance the safety, accessibility, and overall experience for all who use this valued community resource.

This work is being made possible through funding provided by a Local Recreation Improvement Grant that the Borough received from the State. The project reflects our continued commitment to maintaining and improving our shared outdoor spaces for residents of all ages.

Phase I of the Construction activities are expected to begin on or about May 1st, 2026. The work will take approximately 2 weeks to complete. The construction activities will take place between the hours of 8 am and 4:30 pm Mon - Fri. Construction activities may include trail resurfacing, drainage improvements, and general maintenance along certain sections of the Path, starting at the Mountain Ave entrance to approximately 2000 LF down the trail. During this time, you may notice temporary closures or detours in affected areas. We will make every effort to minimize disruptions and ensure that work is completed as efficiently as possible.

We appriciate your patience and coopertion while the trail is improved and we work to make it more usable and  enjoyable trail for everyone. 

Best Wishes,

Mayor James "Jim" Kelly
