Over the past few decades, downtown Seattle has evolved into one of the most dynamic urban centers in the country. Downtown Seattle Association (DSA) creates a healthy, vibrant downtown for all. With the support of their diverse corporate, nonprofit and resident members, they are leading downtown’s recovery and providing vision and leadership on the critical issues and opportunities facing Seattle’s urban core. DSA is the co-host for IDA's 70th Annual Conference & Marketplace in September 2024.
