Route 1 Housing Program In an effort to enhance and preserve the quality of the existing housing supply in the City of Chelsea, the City has premiered the Route 1 Housing Enhancements Program. The Program provides assistance to homeowners seeking to address sound attenuation, air quality improvements, and exterior repairs. Targeting properties adjacent to Route 1, the Program strives to mitigate the adverse public health effects caused by Route 1, including, but not limited to, noise pollution, degraded air quality, and property damage that occurred during recent state construction.
