Board approves lot split at large corner lot with setback and driveway stipulations

The Nashua Zoning Board of Adjustment voted 4–0 on Aug. 13 to grant a variance allowing the subdivision of a large corner parcel at 55A Bridal Dunstable Road into two residential lots, despite opposition from a rear abutter concerned about drainage, wetland buffers and driveway routing.

Attorney Morgan Hollis, representing the Bentley Family Trust, told the board the 40,149-square-foot parcel meets minimum lot area but falls short at the setback-line measurement for lot width; the proposal calls for one lot with 100.2 feet of width where 120 feet is required. Hollis presented an appraiser's report and site plans and offered to stipulate that any new home would be located at least 70 feet from the rear property line.

Neighbors, led by John Wagner, said a perennial stream (which they called a stream rather than a drainage swale) has overflowed and flooded yards in the past and cautioned that wetland buffers and drainage must be examined during subdivision review. Hollis and staff responded that city GIS and NHDES mapping identify the feature as a constructed drainage swale, not a jurisdictional wetland, and that subdivision review by the planning board will examine drainage and driveway routing.

After discussion the board approved the variance and added conditions: the proposed home must be set back no closer than 70 feet from the rear property line and driveway access for the new lot must be from Bridal Dunstable Road. The motion also noted that if contrary wetland findings surfaced later, additional review could be required. A 30-day appeal window applies.
