Northfield staff warns floodplain rules limit storage options at 35 Pleasant Street

A Northfield resident interested in buying and using 35 Pleasant Street for equipment and storage heard cautionary advice from planning staff on May 28 about floodplain limits and permitting.

Staff (Speaker 2) reviewed a map showing that a portion of the parcel encroaches on the town's special flood hazard area and said "not a lot of stuff can be done there." The owner prospect, referenced in the meeting as Mark Fournier, said he hoped to remove several small sheds, tidy the lot and perhaps erect a single metal storage building to hold his electrical equipment and vehicles.

Staff walked the board through the zoning and floodplain guidance: the cross-hatched red area is the special flood-hazard area (1% annual chance), plain red indicates the floodway and the gray is a 0.5% annual-chance zone often called the 500-year flood area. Staff said improvements to existing structures may be permitted or allowed by conditional use, but building a new principal structure in those zones is generally restricted.

"There's a section of our flood plain regulations, which honestly need to be updated," Staff said, and added that some improvements can be treated as "permitted" or "conditional use review" depending on the details. Staff also warned that state review is sometimes required for "substantial improvements" (described in the meeting as a ~50% threshold) and recommended the owner consult the town assessor and a river scientist, Rose Watts, to determine whether proposed work would trigger state review.

Board members and staff discussed technical safeguards for accessory structures in flood-prone areas: elevating electrical systems above the base flood elevation, installing louvered flood vents on at least two sides, and anchoring structures to resist washout. Staff advised the prospective buyer to verify whether the lot is on town water and sewer and to confirm the base flood elevation (FPE) for the site before buying or investing.

Staff said they would follow up with additional guidance and consult Rose Watts and state reviewers as needed so the prospective buyer knows whether improvements are viable without extensive state-level triggers.

What happens next: staff will contact the river scientist for site-specific advice and notify the prospective buyer of permitting constraints; any formal application would return to the DRB for review.
