The mission of the Downtown Stockton Alliance (DSA) is to promote business, housing, arts and entertainment to help create a vibrant, sustainable, urban community in Downtown Stockton. DSA is a public/private partnership uniting almost 1,000 property owners and downtown businesses. The non-profit DSA was incorporated in 1996 as a 501(c)(6) corporation and officially began operations in 1998. Funded by a Property Based Improvement District (PBID) which allows property owners to self-assess on properties and a Business Improvement District (BID) allowing business owners to self-assess their businesses, the Downtown Stockton District was voted into creation in 1997, renewed for a second five-year period in 2002, next for a ten-year period in 2007, and most recently in 2017 for another ten-year period until 2027.
