21st Street is a commercial and residential street near the Paso Robles Event Center, home of the California Mid-State Fair. The street, one of four railroad crossings in town, was established decades ago in a natural drainageway. A concept plan was prepared for five contiguous blocks of 21st Street, between Vine Street and Riverside Avenue, transforming them into a green, complete street that meets several objectives, including: containing the 10 year storm within the street section; increasing groundwater recharge; improving pedestrian and bicyclist mobility; and reducing sediment into the Salinas River.
