The Hopewell Township Planning Board has granted final site plan approval for a proposed 108,000-square-foot warehouse on Route 31, clearing a major local approval hurdle for a project that drew lengthy debate over its appearance, traffic, lighting and potential impact on surrounding properties earlier this year.
The board voted 6-0 Thursday, Oct. 22, to approve the project at 61 Route 31 North after the developer returned with revised architectural plans, additional landscaping, updated lighting designs and responses to fire safety and stormwater management concerns.
The decision follows the board’s July 23 vote to grant preliminary approval while withholding final approval until several outstanding design questions could be resolved.
The project, proposed by Hopewell Solar LLC, would occupy a 12.42-acre industrially zoned property along Route 31, south of Mavis Tire. It would include approximately 108,000 square feet of warehouse and office space, 17 loading dock positions and parking areas.
Although the proposal complies with the township’s zoning requirements and does not require variances, board members spent considerable time during earlier hearings questioning how the large industrial building would fit along one of Hopewell Township’s main roadways.
At the July hearing, those concerns led the applicant to agree to return for final approval rather than seek a vote on both preliminary and final approval that evening.
A new look for the warehouse
Much of Thursday’s presentation focused on changes to the building’s appearance and the landscaping intended to screen it from Route 31.
Architect John Anderson presented revised renderings featuring warmer, more muted exterior colors in place of the lighter gray tones shown in earlier designs.
Anderson said he had worked with township planner Frank Banisch to find ways to make the building less visually prominent behind the planned landscaping.
The revised design incorporates beige, brown and muted green tones, along with architectural accents and entry canopies.
Project engineer Russell Smith also presented an expanded landscaping plan that adds 106 white pine trees to provide year-round screening. The evergreens would be planted at approximately 14 to 16 feet tall, supplementing the hundreds of deciduous trees and thousands of shrubs already included in the plans.
The additional trees would be concentrated along Route 31, with some placed near the rear of the property to provide screening toward neighboring residential properties across the railroad tracks.
Renderings submitted to the board showed how the building would appear when the landscaping is first installed and after the trees mature.
Lighting plans were also updated to address concerns raised during the preliminary approval hearings. The revisions coordinate exterior fixtures with the building’s entry canopies and account for lighting at the proposed monument sign.
Those issues had been among the principal reasons the board declined to grant final approval in July.
Fire access and stormwater conditions
The final approval also addresses several technical concerns involving emergency vehicle access, stormwater management and the building’s water supply.
One outstanding issue involves the proposed driveway entrance from Route 31.
Smith explained that the entrance was widened to accommodate the township’s large fire apparatus, including a tower truck, entering and leaving the property from either direction.
Because the proposed driveway exceeds the width ordinarily allowed by the New Jersey Department of Transportation, the applicant has requested a waiver as part of its state highway access permit application.
That approval remains pending.
Smith said the developer has been communicating with NJDOT and expects the process could take another month or two.
The revised plans also identify fire lanes and hydrant locations, while additional engineering will be needed for the property’s private fire protection water system.
The board discussed stormwater facilities near 28 parking spaces that would initially remain unpaved. Those spaces would be reserved for possible future use if additional parking is needed.
The applicant agreed to include a maintenance schedule for drainage inlets in that area as a condition of final approval.
Water use will also remain restricted under conditions established during the preliminary approval.
Board attorney Trishka Waterbury Cecil confirmed that the property would be limited to 2,500 gallons of water use per day, a restriction tied to the site’s septic capacity. Office space would also be limited to 12,750 square feet.
Waterbury Cecil said conditions from the preliminary approval that have not yet been satisfied would carry forward into the final approval.
Questions remain about future tenants
Although the board approved the revised plans, the hearing again highlighted uncertainty about how the building will ultimately be used.
The developer has described the project as a speculative industrial building intended to accommodate multiple smaller businesses rather than a single large distribution operation.
No tenants have been identified.
During previous hearings, representatives said the building could serve contractors or other businesses needing a combination of warehouse and office space. The plans nevertheless provide loading docks and circulation areas capable of accommodating tractor-trailers.
That uncertainty continued to concern residents who questioned how traffic, water use and environmental impacts could be evaluated without knowing what businesses would eventually occupy the building.
The traffic analysis presented during the preliminary approval process projected 13 vehicle trips during the morning peak hour and 16 during the evening peak hour, using standard industry trip-generation estimates rather than traffic counts conducted on Route 31.
Traffic was not the subject of new testimony during Thursday’s final approval hearing.
Residents also raised questions about stormwater runoff and nearby wetlands, including whether the eventual intensity of operations could affect the site’s environmental impact.
Smith said the stormwater management system was designed to meet state requirements and that the amount of paved surface, rather than the identity of the eventual tenant, was central to the runoff calculations.
Applicant attorney Christopher Costa said future occupants would be required to operate within the limits of the approved site plan.
Board member Rex Parker acknowledged the uncertainty surrounding the eventual tenants but said the restrictions established through the approval process provided safeguards.
“There’s just a lack of insight into knowing what the actual usage of the building is going to be, but the parameters that are set around it I think safeguard us,” Parker said.
He noted that the property’s zoning limits the uses that can occupy the building, regardless of who ultimately leases the space.
What happens next
Thursday’s vote completes the Planning Board’s final site plan review, but the developer must still satisfy the conditions of approval and obtain outstanding permits before construction can proceed.
Among those outstanding matters is NJDOT approval for the widened Route 31 driveway entrance.
Additional technical details involving fire protection, stormwater maintenance and other site improvements will also need to be addressed through the approval and permitting process.
The board’s decision concludes a review that began earlier this year and included extensive discussions about the appearance and operation of a warehouse on a prominent stretch of Route 31.
While the final plans now establish how the building and property can be developed, the businesses that will eventually occupy the warehouse remain unknown.
