Downtown
Central San Mateo, including downtown San Mateo and Central Park, is located between Hwy 101, El Camino and 1st to 9th Avenues. Downtown San Mateo features Central Park, buildings and businesses built near the tracks along today’s Main Street and Railroad Avenue in the 1800’s.
The downtown area saw major growth after San Mateo incorporated as a town in 1894, historic buildings from the 1890s to the 1930s surround the two block long walkway of Main Street which is halfway between B Street and Railroad Avenue.
A self guided Walking Tour is available through the Downtown San Mateo Association (DSMA) to learn more about the history and architecture of the downtown district.
The Downtown San Mateo Association (DSMA) is a coalition of San Mateo businesses who promote business and civic activity and work to improve the downtown experience for all. It is a 501(c) 6 non-profit corporation and all businesses that open in the downtown area are automatically enrolled through their business license fees.
Fiesta Gardens, Hillsdale, 25th Avenue, and across El Camino the Borel, Aragon, Baywood, and Gramercy-Mounds El Cerrito neighborhoods surround the downtown San Mateo area. The streets between the 101 and ElCamino are mostly a grid system while other neighborhoods especially Park (San Mateo Park) offer streets than curve and intersect at different angles with landscaped islands.
Numbered streets continue on the other side of the 101 but only a few go beyond CalTrain’s railway. The exception is 3rd Avenue, is also named J Hart Clinton Drive in honor of the San Mateo Times Publisher, it follows along the Bay past Seal Point ending before the San Mateo bridge.
While the numbered streets continue up to 17th Avenue at least on the SW side of Railroad Ave to El Camino Real, the alphabetically named roads beginning with B Street then Railroad Ave, Claremont, Delaware (the NE border of Downtown San Mateo), Eldorado, Fremont, Grant, Humboldt and Idaho Streets run parallel to the bay.
On the other side of the 101 and west of El Camino the neighborhood street names do not follow a citywide pattern. The exception being the 25th Avenue Neighborhood with its numbered streets counting each block further away from downtown and some of those numbered streets continue into Beresford Park.
