The city will be creating a full inventory of historical properties with the help of a $10,000 state grant from the Massachusetts Historical Commission. The city several years ago developed a partial inventory of historic homes with the help of a previous state grant. Using the new grant and $10,000 of its own funds, Woburn plans to hire a consultant to continue that work, according to Edmund Tarallo, the city’s planning director. The consultant will research homes identified by the city’s Historical Commission to see if they merit inclusion in the inventory based on their historical or architectural value. Tarallo said the local commission will use the list as a resource in administering the city ordinance that allows it to delay demolition of buildings it deems historically significant. He said the inventory also will help the commission identify properties that might be candidates for inclusion in the National Register of Historic Places.
