The grounds of the old Gerstle family mansion were donated to the City of San Rafael as a public park in the early 1930's. The antiquated play equipment had been gradually removed for safety reasons until only one piece remained. In 1988, the Gerstle Park Fund was created by a group of concerned neighbors to raise money for a new playground. Pedersen Associates helped the community acquire grants and private contributions by documenting and promoting citizen's efforts while designing the new playground. The playground is designed to improve access and increase play value while reflecting the historic character of its surroundings. Its sand filled terraces are wrapped by a stone bench wall that protects adjacent trees and contains the new play equipment designed for safety, diversity and interaction between children, friends and parents.
