Jamacha, San Diego

Jamacha is named for the Jamacha Valley and Rancho Jamacha, a Mexican land grant estate. The name was variously spelled Xamacha, Jamacha', 'Jamacho, and Gamacha until Jamacha was fixed as the official spelling in the early 20th century. The word is likely derived from a Spanish adaptation of the Kumeyaay Indian word Xamca, meaning "wild gourd."[2]

Jamacha is a largely residential neighborhood, with mostly single-family houses mixing with some multi-family development. There is also some small-scale commercial development in the neighborhood.[3]

The Skyline-Paradise Hills Community as a whole make up approximately 4,500 acres. Much like the surrounding neighborhoods of Bay Terraces, Skyline, and Paradise Hills, Jamacha is comprised predominantly of low-density single-family homes spread across the hilly area. A major geographic feature is Paradise Valley, which runs on an east-west axis through the middle of the community and gives rise to the Paradise Creek, which flows into San Diego Bay. Jamacha, along with Lomita, Skyline, and North Bay Terrace, are directly north of Paradise Valley.[4]
