Our Chamber office and CA Welcome Center HMB (Visitor Center) reside at 508 Main Street as of 2026. Since moving, we have seen a significant rise in walk-ins. Roughly 95% the walk-ins ask for direct recommendations and community info. More than 90% of those individuals walk out with some peice of local collatteral, many of whom gather so many magazines and brochures that we give them a bag to hold it all! We also mail relocation and visitor packets full of our Chamber Partner’s brochures and the annual Coastside Guide.
