An extensive roadwork improvement project that has been a decade in the planning has been targeted to begin this summer. Moore Street, Park Place, Vandeventer Avenue and Willow Street are the thoroughfares that will be affected by the project, which will include sanitary sewer improvements, storm drainage work, curb ramp upgrades, and road resurfacing, residents and business owners were told at a meeting Monday night in Witherspoon Hall.

Some 40 people turned out to hear details of the project from Princeton’s Municipal Engineer Bob Kiser, Assistant Municipal Engineer Deanna Stockton, Sergeant Thomas Murray from the Princeton Police department, and other officials. Mayor Liz Lempert introduced the program. “This is a project long in the making,” she said. “We’re very excited to be at this step. This is the first road project to be undertaken in the new [consolidated] town.”

Mr. Kiser told residents, some of whom have been consulted as the project was in its planning stages, that it will go out for bid within the next two weeks. Once a contractor is engaged, the work should start at the beginning of July and last four months. Mr. Murray, who is Princeton’s Traffic Safety Officer, urged those who may have special needs or special events planned to let him know as soon as possible.

“There will be some disruption,” he said. “But we’ve tried to phase it out. We realize the importance to businesses and residents alike, so we’re trying to limit the construction to one street at a time. We’re taking mail delivery and trash pickup very seriously.”

Ms. Stockton said the construction would take place weekdays from 7 a.m. to 6 p.m., with the possibility of some Saturdays as well. Park Place and Vandeventer Avenue are priorities for the initial underground work. The town will try to keep the Park Place municipal parking lot open with one access, and part of the lot will be used as a staging area for the construction, secured by fences.

As for on-street parking, meters will either be pulled or have bags placed over them but will be reopened for residents to use when it is determined to be safe. “Businesses on Nassau Street that need to get deliveries in through the Park Place lot should contact the engineering department, and also let us know about any large functions you have planned,” Ms. Stockton said, adding that roads will be passable at the end of every workday. An effort will be made to find parking for residents whose parking spaces are displaced during the construction.

Among the improvements to be scheduled are replacement of the old sanitary sewer line and water main on Park Place, some sanitary sewer work on Moore Street between Nassau and Franklin streets and all of Vandeventer Avenue. New pavement will be installed on all of Moore Street, Park Place, and Vandeventer Avenue. Cost of the project is estimated at just over $1.5 million.

Electricity will not be affected by the construction, but the water will be turned off at times. Mr. Kiser told residents that notices of water shutoff will be posted on the princetonnj.gov website, and emailed to those residents who supply their addresses.

Robert Hough, the town’s Director of Infrastructure and Operations, gave details of sanitary sewer improvements that will take place. Arborist Greg O’Neil talked about tree removal and protection.

The project has taken a decade to prepare because of its complexity. “There were lots of challenges, in terms of the sanitary sewer lines that had to be relocated,” Mr. Kiser said the day after the meeting. “We needed to meet with homeowners regarding an easement. Also, extensive survey work had to be done to determine where the new sewer line has to be installed, and to determine drainage improvements that were needed.”

The next meeting will be attended by the contractor selected for the job, and residents will have a chance to ask questions. As for this meeting, “We were thrilled with the turnout,” Mr. Kiser said. “People asked lots of good questions.”
