The Metropolitan Beaches Commission is holding a public hearing Tuesday from 6 to 8 p.m. in Room T-102 of North Shore Community College’s Lynn campus, 325 Broad St. The hearing is the second of nine that the commission is holding around the Boston area this summer to give people a chance to offer their opinions on the condition of public beaches and how they might be improved. Six years ago, the state panel issued a report that said state-owned beaches — which include King’s Beach in Lynn and Nahant Beach — were poorly maintained and in need of capital investments. The commission this spring reconvened to evaluate whether the state action that report spurred has made a difference and what further changes are needed. The panel is holding the hearings to seek feedback from local beachgoers. Among those expected to be present at Tuesday’s meeting are the commission’s cochairs, state Senator Thomas M. McGee, a Lynn Democrat, and state Representative Kathi-Anne Reinstein, a Revere Democrat, and commission members Robert Tucker of Lynn and Mark Cullinan of Nahant.
