Founded by DSA in 1999, the Metropolitan Improvement District is a business-improvement area spanning 285 square blocks in downtown — from Denny Way to Pioneer Square and from I-5 to the waterfront. With funding from MID ratepayers, DSA provides cleaning, safety, concierge and public-realm activation services in six center city neighborhoods.. Our ambassadors are on the streets of downtown every day, ensuring an inviting, safe and clean urban experience for everyone. The MID was renewed by the Seattle City Council in 2013, with support from a majority of district ratepayers. Over the past year, we’ve enhanced our work in downtown to keep pace with the area’s growth. We now employ nearly 100 ambassadors, we’ve extended daily hours of operation, and we’ve added additional cleaning equipment. From leaf cleanup to graffiti removal, a few key statistics are captured below.
