About Us

MID Clean 1st AveThe Metropolitan Improvement District (MID) is a nonprofit 501(c)(6) service organization that provides streetscape cleaning, maintenance, hospitality and public safety services, as well as destination marketing, human services outreach, research and market analysis for Downtown Seattle. Founded by the Downtown Seattle Association in 1999, the MID is financed through tax assessments on Downtown properties and covers a 285-square-block area in Downtown Seattle’s core. Each day, more than 100 Downtown Ambassadors patrol the streets of the Belltown, Denny Triangle, Pioneer Square, Retail Core, Waterfront and West Edge neighborhoods in order to maintain Seattle’s healthy, vibrant urban core.

In May 2013, The Seattle City Council voted to renew the MID in Downtown Seattle for another 10 years, expanding the MID’s service area (see maps below) from approximately 225 to 285 square blocks with the addition of the Belltown neighborhood and several added blocks in Pioneer Square.

The MID’s work is designed to keep Downtown’s participating neighborhoods inviting, clean and safe.
