SAUGUS – The Board of Selectmen is slated to conduct two show-cause hearings when they meet this evening in the Town Hall auditorium.But before the 7:30 p.m. session gets under way, board members will hold a separate meeting at 6:30 p.m. in the first-floor conference room to discuss the town’s sewer project update.The first show-cause hearing on the agenda is for the DePaolis Group Inc., doing business as Urban Crust Pizzeria, an award-winning restaurant featuring hand-tossed pizza at 43 Jackson St. in Cliftondale Square.The board will determine whether to cancel, revoke or suspend the establishment’s common victualer’s license, entertainment license, and any other permits. Urban Crust reportedly has failed to pay its municipal taxes and fees for over 12 months in breach of its payment agreement, according to documents on file at the selectmen’s office.The other show-cause hearing concerns Twitters Bar & Grille, inside the Square One Mall at 1201 Broadway. The hearing is being held because of a variety of rule violations and for making changes without notifying the selectmen.The 6,000 square-foot establishment occupies the space where Iron Works Grill and Tavern once operated in the mall.When Twitters Bar & Grille opened in 2010, it was subject to a litany of complaints from neighbors. Among the issues were excessive noise from cars as they left the restaurant and hours of operation.Twitters Bar & Grille has a 12-seat bar and does not host entertainment.The board will also hear an application for a special permit from Michele Davison, owner of Moni J Bella Hair Studio, to create a salon offering hair, facials and waxing at 57 Jackson St.Another local businesswoman, Deborah Grillo, doing business as Victor’s Italian Restaurant, 560 Lincoln Ave., is seeking a common victualer’s license and a variance to waive the grease trap requirement.Guests invited to the meeting include Police Chief Domenic Dimella, the Saugus 8th grade basketball travel team, and the Saugus Youth Hockey Squirt team.The hearing for Pamela Avedisian has been postponed to June 7.Avedisian or her attorney have been before the board on several occasions related to her plans to open a restaurant on Route 107 at the site of the former Atlantic Lobster Co.Avedisian is currently on notice from the Board of Selectmen that she must use or lose the liquor license she holds. Selectmen contend Avedisian has not moved forward with plans to develop the property and, as a result, should not be allowed to keep the license along the Salem Turnpike that is flanked by marshland.The board granted the license to Avedisian in 2009 when she unveiled plans to establish a function hall on the property.
