Pacifica is one of the youngest communities in San Mateo County and yet its Spanish origins make it one of the oldest. Between 1906 and 1920, small settlements sprang up around the stations of the Ocean Shore Railway, but the coast north of Devil's Slide remained sparsely-populated until the post-warbuilding boom. Then, developers such as Oddstad and Doelger began a rush ofhome-building and thousands of small houses covered the valleys and crept upthe hillsides, each its own distinct community. In 1957, Pacifica became anincorporated city, consolidating the communities of Edgemar, Pacific Manor,Westview (Pacific Highlands), Sharp Park, Fairway Park, Vallemar, RockawayBeach, Linda Mar, and Pedro Point.
