SAUGUS-Driven by the collapse of a retaining wall on Hitching Hill Road, town officials have joined forces to draft a bylaw that would restrict any builder’s ability to construct certain walls.Building Inspector Frederick Varone said he was shocked when he learned years ago that Saugus allowed walls over six feet in height.”A lot of cities and towns don’t allow people to raise walls without a swale,” he said, referring to a drainage method.Varone said Revere’s bylaws don’t allow for one resident to raise a driveway even six inches over another’s without a swale. In Saugus however, residents could technically build 10-foot walls around the perimeter of their property, fill them in and build a house on top.”I’ve seen it happen,” he said.Police Chief Domenic DiMella said he also remembers when that very scenario played out on Heritage Lane not so long ago.”It snowballs into many police calls, and mediation with the neighbors and many hours for us,” he said.DiMella and Varone met Thursday to discuss drafting a bylaw with Selectmen Donald Wong and Peter Rossetti as well as Fire Chief James Blanchard, Town Counsel John Vasapolli, Developer Kevin Procopio and Hesper Street resident George DeCandia.Varone said he also thought it was crazy to allow a developer to build a wall atop a steep slope with houses below as happened on Hitching Hill Road.The problem is that local and state officials, including those that monitor the Hillside Protection Act, approved the wall on Hitching Hill Road.Varone said that is largely because an engineer signed off on the project at every level, a method that he proposed to change.Varone said walls over six feet should be subject to a peer review and a review from in independent third party engineer as well as the project engineer.Procopio said as a developer he wouldn’t disagree but he also thought the Planning Board should be able to sign off on the plans from the start.Vasapolli suggested at least one representative from both the Planning Board and the Conservation Commission should be asked to join the group to give their insight on a potential bylaw.Rossetti said he asked the various department heads to sit in on the meeting because a wall collapse such as Hitching Hill Road impacts the entire town. The Fire Department spent 36 hours monitoring the homes along Hesper Street at the base of the crash while police officers continuously kept the curious away from the top of the scene.Town Manager Andrew Bisignani hired a geotechnical engineer to the tune of approximately $15,000 to test the stability of the wall and the Building Inspector has had to do his share of legwork.”The reason we’re doing this is Hesper Street, but it will be town-wide because it affects everyone in town,” Rossetti said.The committee will meet again in late August or early September to hash out the details of a draft bylaw. Their goal, according to Rossetti is to eventually have a bylaw to present to Town Meeting.
