Saranap (until 1913, Dewing Park) is a residential census-designated place (CDP) within central Contra Costa County, California. Lying at an elevation of 180 feet (55 m), it is bounded on the south and east by portions of Walnut Creek (including the gated senior residential development Rossmoor) and on the north and west by Lafayette. Saranap's ZIP code is 94595, but is addressed "Walnut Creek, CA" for delivery purposes as this is the postal designated city name used by residents. The community is in telephone area code 925. Saranap's population as of the 2010 census was 5,202.Saranap has had numerous opportunities to be annexed as either part of Lafayette, or of Walnut Creek. These have been largely resisted by the occupants, whose land use is governed by county rules. These include the ability to keep small aviaries and bees, which can be highly restricted by law in surrounding cities, and in newer neighborhoods by restrictive covenants. As the local school district is independent of these city boundaries, and some of the cities impose additional parcel taxes, residents have little incentive to change the status quo. Only a minor addition was made to Lafayette from Saranap in recent decades, adding only one more street and being largely motivated by marginally superior housing values associated with the city of Lafayette.

St. Anselm's Church in Lafayette, California is an Episcopal church noted for its architecture. In 1959, the Episcopal bishop of California, James Pike, hired Olav Hammarstrom to design St. Anselm's. Hammarstrom was a Finnish architect who worked with Alvar Aalto and later with Eero Saarinen and The Architects' Collaborative. Hammarstrom worked with the San Francisco architectural firm of Marquis and Stoller on St. Anselm's.The concept for St. Anselm's was based on the Chapel of St. James the Fisherman in Wellfleet, Massachusetts, also designed by Hammarstrom. The church's interior features exposed redwood and cedar beams and columns. Using a "church-in-the-round" approach, the square sanctuary is in the center of the structure surrounded by redwood pews. The church seats approximately 450 parishioners in an octagonal space with everyone seated within seven rows from the altar. In December 1960, Time wrote that St. Anselm's design, in which the clergy and choir sit among the people, "appeals to Americans' democratic instincts."Ground was broken on the church in May 1960, and it was dedicated in October 1960. After seeing the completed church, Bishop Pike noted, "At St. Anselm's, the congregation is not the audience for a performing clergy and choir. The clergy, choir and congregation perform together, and God is the audience."A history published by St. Anselm's notes that the building's design was covered extensively in the news, before and after it was completed. Coverage included the December 1962 issue of Better Homes and Gardens and the December 26, 1960 issue of Time magazine, as well as San Francisco Bay Area newspapers, the cover of the September 1959 issue of "Pacific Churchman", the October 1960 issue of "This Earth" magazine.
