Somerville planners weigh state 'real rules' and local stormwater updates

Planning staff briefed the board on Jan. 28 about recommended changes to the borough’s stormwater ordinance and how recent state regulations — described in the meeting as the state’s updated "real rules" — affect local drafting.

Mike, the board’s planning staff, summarized the Planning Board’s Dec. 10 guidance: keep the borough’s existing major-development threshold, avoid requiring infiltration or groundwater recharge across urban sites where state rules exempt such measures, and avoid creating new annual fees or mandatory easements for stormwater systems. He told the board that the New Jersey Department of Environmental Protection issued a Jan. 20 amendment that narrows the "redevelopment" exemption: when existing paved surfaces are disturbed, municipalities must count that disturbance and may no longer automatically exempt such work from stormwater obligations.

"The recommendation was to keep the major development definition that's in the current ordinance there intact and uh not to uh do uh infiltration," Mike said, explaining the board’s earlier position and the state’s new timing. He recommended waiting to see the final state guidance and aligning borough language with the state to avoid redundant amendments.

Members expressed concern about the cumulative effect of small projects and the administrative burden of expanded permitting. Several members opposed routine adoption of a third-party review requirement for every application, saying it could lengthen processing, raise fees and reduce local technical oversight. Mike and other board members noted that certification requirements already govern municipal review engineers and that third-party reviews should be narrowly targeted if used.

Tim Deal, chair of the Environmental Commission, urged the board to retain enhanced local standards and to avoid sending a message that Somerville will accept the state baseline as the ceiling. "Stormwater is not a personal property issue ... it's really a public safety issue," Deal said, and he asked the board to refine thresholds and to provide simple compliance pathways for small homeowners' projects so repairs and modest improvements aren’t unduly penalized. Jeff Kaiser, a local resident, similarly encouraged use of incentives such as permit-fee reductions for homeowners deploying green infrastructure like rain barrels.

The board did not take any ordinance votes tonight; an ordinance (2780260120) that had been on the agenda was pulled to allow further fixes and will be reintroduced at a future meeting. Staff said they would circulate the state guidance summary and updated drafts before the next meeting and asked the Environmental Commission to participate in follow-up discussion.
