Northampton panel clears Glendale Road sewer and trail with conditions after resident concerns

Northampton — The Conservation Commission voted unanimously on April 2 to issue an order of conditions for a cluster development on Glendale Road that includes a pressure sanitary sewer through an existing gravel access road and a public walking trail, after hearing technical details and extended public comment about environmental and access impacts.

David Cameron of Fleetwood Environmental Solutions, representing the applicant, told the commission the work within the commission’s 200-foot riverfront jurisdiction is limited to a sewer installed in the footprint of an existing access road, small amounts of grading for three stormwater management features and an unpaved trail. “The only items within the commission’s jurisdiction are a sewer, the sewer line, this rain garden, this rain garden and a tiny bit of grading associated with this infiltration basin,” Cameron said in his presentation.

Cameron said the applicant had applied several compliance pathways under the Massachusetts Wetlands Protection Act (310 CMR 10.58) and that some stormwater features qualify as exempt structural measures when no practicable alternative exists. He quantified the parcel’s riverfront area at roughly 374,000 square feet and said the proposed alterations in the riverfront reach were on the order of 6,000–7,000 square feet, with about 3,000 square feet of grading for stormwater basins.

Residents and abutters raised multiple concerns during the public-comment period. Carrie Neorchuk, who lives on Glendale Road, said the irregular soils of a former gravel pit make a stream crossing and a stormwater basin harder to predict. “Previously excavated and backfilled areas can have highly variable and unpredictable soil conditions,” Neorchuk said, urging extra scrutiny of long-term settlement risk near the proposed sewer crossing.

City Councilor Chris Stratton and other neighbors asked for a gentler, more accessible trail alignment and warned that desire paths could form if the official route is steep or indirect. “I want to express a concern that the path be routed and laid out as gently and as invitingly as possible,” Stratton said, noting the city’s interest in linking the donated open space to an existing regional trail network.

Several speakers questioned where the sewer ultimately connects and whether East Hampton authorities had approved the downstream connection. Commission staff and the applicant said an East Hampton Department of Public Works letter in the planning record indicates the connection on the East Hampton side is acceptable; staff reminded the public that utility routing and broader site access questions generally fall to the planning board, not the conservation commission.

On technical questions, the applicant described a minimum of 18 inches of cover between the bottom of the proposed sewer pipe and the top of an existing culvert and said the road fill over the culvert provides additional protection. The applicant also explained streamflow monitoring done in 2024 that showed intermittent flow upstream of the access road and perennial flow downstream of the culvert due to an unknown subsurface source.

After hearing the presentation, technical clarifications and public comment, Commissioner Mason moved to close the hearing and then moved to issue an order of conditions. The commission added a specific expectation that the applicant inform the commission of any deviations from the trail routing shown in the submitted plans before construction and notify staff of the final routed trail after construction. The motion carried on a unanimous roll-call vote.

Next steps: the planning board will consider site layout, parking and access details; the commission’s order focuses on protecting jurisdictional resource areas and tracking any changes to the trail footprint inside the riverfront corridor.
