There’s a new one-stop website for the city’s 20 main streets districts. The portal— bostonmainstreets.org— launched this week and is “designed to unify the network of Main Streets districts and provide a one-stop-shop of information for residents, businesses, and tourists alike.”

“This new website is another example of the Main Streets Foundation commitment to each of our 20 main streets districts,” said Mayor Martin J. Walsh. “This investment, this tool, will help Boston residents and visitors support our strong local small business.”

“When people think of Boston, they should not just think of downtown,” said Joel Sklar, Board Chairman for the Boston Main Streets Foundation.

“They should think of the vibrant farmer’s markets in Roslindale, concert halls in Allston-Brighton, boutiques along Centre Street in Jamaica Plain, the waterfront parks in East Boston, and the authentic international cuisines across Dorchester, Roxbury and Chinatown.

The website includes an events calendar, resources for local businesses, including applications for City of Boston small business certifications and news about promotions.
