Zoning board approves relocation of failing drainage line at 3 Spaulding Street
Summary
The Zoning Board approved the City of Nashua Division of Public Works' request to relocate a failing municipal drainage line that runs under a house and discharges to Salmon Brook. The board found the project meets wetland-buffer criteria and called it a critical safety improvement.
The Nashua Zoning Board of Adjustment unanimously approved a special exception allowing the discontinuance and relocation of a municipal drainage line at 3 Spaulding Street, work that the city says will repair a segment of pipe that dates to around 1890 and is failing.
Earl Blatchford of Haynor Swanson, representing the city, told the board video inspection showed root intrusion and failure in the 15- to 18-inch line under the Spaulding Street property. He said the plan is to relocate the drainage around the house and create a new outfall at Salmon Brook about 50 feet downstream; the existing pipe portion at the brook will be plugged and filled with flowable fill to eliminate voids.
Blatchford said the Conservation Commission and shoreland permitting process have reviewed the work and that a shoreland permit was issued on Feb. 20. He described permanent impact as limited to about 14 linear feet of bank for a headwall and riprap; other disturbances would be temporary and would be restored. During deliberations, a board member called the project a "critical safety project" and the board voted unanimously to approve the special exception.
The board found the project would not unduly impair pedestrian safety or municipal systems and noted potential risk to the adjacent house if the line was left unrepaired. The chair recorded the unanimous approval and the usual appeal notice.
