[8] Its construction was led by the community volunteer group Friends of the Rockridge-Temescal Greenbelt (FROG), which continues to maintain and improve the park.

[6][2][9] The park is a thin stretch snaking for three blocks from Hudson to Clarke streets and running parallel to Claremont Avenue, in Oakland, California.

[4][16][15] It depicts an underwater panorama of sea creatures and divers, by artist Gary Graham and a team of students.

[4] These elements were the result of a public art project started in 2005, with local artists and community selecting among multiple submissions.

[7][18] In the 1960's, with greater urbanization closer to the creek, concerns about flooding from winter rains grew, and a section of the creek from Lake Temescal to Hardy Park in Rockridge was culverted, along with the plans to construct of a section of Highway 24 between the Caldecott Tunnel and downtown Oakland.

[6] On this site the Frog Park was later built in the 2000s and it included the restoration of a faux "reconstituted creek" filled by water pumped up intermittently from the culvert below.

[6][2][22] The Rockridge neighborhood had been built up around 1910-1930, and was densely developed, making for a dearth of green public open spaces.

However most of the strip in-between, mostly owned by the Alameda County Flood Control District, was left unused and fenced-off with overgrown weeds on it.

[15] After much deliberation and research by the group, volunteers Peter Hollingsworth and Tom Dolan outlined a masterplan that envisioned the construction of playgrounds to anchor either end of the linear park; one for toddlers and one for older children.

[26][2][1][10] Ithaca (NY)-based Leathers and Associates, which specializes in custom-designed playground plans and community construction, was hired to guide the project.

[2][4] Groundbreaking happened in late 2001, and about 1,300 volunteers worked over a ten-day period to build two large play structures in the parks.

[26][2] The park is supported by a coalition of local leaders and organizations including among others the Friends of the Rockridge-Temescal Greenbelt (FROG),[4][1] Oakland Parks and Recreation Foundation, Temescal Neighbors Together, Friends of Temescal Creek, DMV Neighbors Association (DNA).

[3][1] With the design they were envisioning in the 2000s including the revival of the Temescal creek, and inspired by the amphibious ecosystem it represented, someone proposed that their acronym be modified to FROG, and that the name of the association be adapted to fit it: Friends of the Rockridge/Temescal Greenbelt.
