Historic Downtown Prosser (HDP) is a nonprofit organization formed in 2006 by community members dedicated to the preservation, enhancement, and revitalization of Prosser’s downtown core. HDP is a designated Main Street community, working within the Main Street America framework through PreserveWA.

As part of this nationally recognized approach to downtown revitalization, we bring together local businesses, volunteers, partners, and organizations to strengthen Prosser’s downtown through economic vitality, design, promotion, and community engagement. Our work is rooted in collaboration, local leadership, and the belief that a strong downtown benefits the entire community.

Our Mission

Create a vibrant and prosperous downtown.
