The Rockville Planning Commission spent a substantial portion of its Oct. 14 meeting reviewing proposed revisions to the building permit application and two new ‘‘Fire Zone’’ documents referred from the town council. Commissioners expressed concern about a proposed broad requirement that all new construction or substantial remodels include fire-suppression systems if hydrants cannot meet code flow and distance thresholds.

Shelley (town clerk) explained the council requested the commission review forms that reflect fire-marshal recommendations after a recent building project revealed a hydrant installed at an owner’s expense did not provide the flow the fire marshal expected. A representative who identified as working for the Rockville Pipeline Company explained the pipeline had allowed a hydrant installation at the owner’s expense but that when it was tested the flow did not meet current fire-code expectations and the owner was required to install a sprinkler system.

Commissioners repeatedly urged testing of Rockville’s hydrants before adopting new broad requirements. Commissioners cited an instance in which a tested hydrant produced roughly 600 gallons per minute (GPM) while they said the fire marshal’s threshold is 1,000 GPM; commissioners asked for formal flow/pressure testing and documented results across town. They also requested clearer, written thresholds in the proposed forms for when a sprinkler system is required (questions included whether small remodels or only new construction would trigger the requirement, building-size thresholds, remodeling scope and distance from hydrants). Participants discussed indoor holding tanks specified in the proposed forms (residential tanks in the 200–300 gallon range with dedicated pumps), larger outdoor tanks for remote properties and the practical and financial impacts (commissioners noted the potential for substantial added cost for homeowners).

Several commissioners recommended returning the forms to the town council with a request that the town or fire district perform a comprehensive hydrant test, clarify whether the forms will be incorporated into the land-use code, and specify remodel thresholds and minimum building sizes or other objective triggers. No formal action was taken; the commission asked staff to request hydrant testing and to seek written clarifications from the fire marshal and water authorities before recommending code amendments.

Direct outcomes from the discussion: the commission asked staff to request documented hydrant-flow/pressure tests across hydrants in both Fire Zone 1 and Fire Zone 2, to clarify the intended scope of the sprinkler requirement (new construction versus remodels and square-foot thresholds), and to confirm whether the Fire Zone documents will be adopted as code or remain administrative forms.
