About Downtown
Lafayette
Downtown Lafayette, located between Mount Diablo Boulevard and the Lafayette Reservoir area, is a walkable and rail-served Lafayette neighborhood with a classic Main Street core and a backdrop of oak-dotted hills. The neighborhood’s character concentrates around the Mount Diablo Boulevard and Moraga Road corridor, where sidewalk patios, independent boutiques, and coffee counters keep the blocks active. Landmarks like the Lafayette Library and Learning Center, Town Hall Theatre, and the Lafayette Art Gallery anchor local culture. Architecture shifts from early 20th-century storefronts to low-rise mixed-use buildings with shaded arcades. Pocket plazas and street trees soften the commercial grid. BART and the regional trail network tie daily errands to outdoor time.
