@wmar2news: 'WHO'S GONNA HELP US?' Residents of the Williams Estates and Peppermint Woods community say a major commercial development across the street is flooding their homes, bringing rats into the neighborhood, and raising concerns about toxic chemicals left behind from a former World War II manufacturing site. Aviation Station, the development site, has plans for a new Walmart and several other businesses. Neighbors say the project is already causing problems, and they worry it will only get worse.
