SALEM – Flooding concerns continued to dominate talks on Thursday regarding the proposed “Big Box” store project slated for Highland Avenue, where a crowd of grumbling Lynn and Salem residents demanded answers.”It’s a good project, but it’s in the wrong place,” said Lynn resident Calvin Anderson. “Why tear down paradise to put up a parking lot?”Several questions were left hanging in the balance at the heated Salem Planning Board meeting, but one major issue – runoff, was quelled by Austin Turner of Tetra Tech Rizzo, a civil engineering services firm hired by Lowe’s.Turner stressed that hooded catch basins and retention basins will be put in place at the site to capture nearly 90 percent of water runoff, sand and silt from oozing in the neighborhoods.”We’re working with the Massachusetts Department of Transportation, and drainage will certainly be on top,” he said. “There are a lot of eyes on this project.”The proposed development is calling for a 153,000 square-foot Lowe’s Home Improvement store and a Walmart on Highland Avenue by the Kennedy Development Group. The project is slated to boost Salem’s tax revenue and Lynn officials are complaining that the massive project will just pose more traffic and environmental impacts for their city.”They never seem to have the answers and this has been going on for nine months,” barked Norm Cole of the Lynn Housing Authority and Neighborhood Development. “There’s always something else that has to happen and we never get to the bottom line. It’s always we’re almost there, but not yet.”Despite Cole’s concern, Bill Ross of New England Civil Engineering, who acts as a third party reviewer for the city of Salem, said the drainage report appeared on target.”I feel comfortable based on information in the reports and think the assumption seems reasonable from the engineer that is predicting reduced runoff,” he said. “They did a reasonably thorough job.”In the plan, Walmart would demolish its existing store and build a larger store with 611 parking spaces that would sit parallel to Highland Avenue.While several area union representatives praised the pending project, resident Kathleen Sabio said she still feels uneasy about it.”Highland Avenue is not wide enough for all the traffic that will be generated by Lowe’s (and Walmart),” she said. “That road services traffic for Lynn, Peabody, Salem and Swampscott and I don’t see how this project will improve anything. It’s going to impact a lot of people for a long time.”Mayor Judith Flanagan Kennedy expressed concern for the ongoing project, but also praised the Salem Planning Board for scrutinizing the often times confusing lingo.”I’m glad to see the board is asking really tough questions, especially regarding maintenance of the structures,” she said. “But, this is still going to be reviewed at the state and federal level.”Traffic impacts were not discussed at Thursday’s meeting and will most likely be on the board’s Dec. 16 agenda.
