Peralta Creek Tree Management

Alameda County Flood Control and Water Conservation District (District) completed tree assessments along Peralta Creek between Brookdale Avenue and School Street (Phase 1) and Davis Street and Brookdale Avenue (Phase 2). A location map is provided for reference. The assessments were conducted by a qualified arborist consultant in order to evaluate the health of the trees, their potential for failure, fire hazard and to identify types of treatment required, including trimming or removal. The tree assessment reports are provided for reference.

Surveys were conducted to determine which trees are on District property or easement. The District has no jurisdiction over trees on private properties.

Phase 1 tree management work has been completed between Brookdale Avenue and School Street. Phase 2 tree management work began on November 15, 2022 for the portion between Deering Court and Brookdale Avenue. Phase 2 tree management was temporarily suspended in mid-December 2022, to comply with environmental permit requirements. The remaining Phase 2 tree management work will resume beginning September 2023 to November 2023 in accordance with environmental permit requirements. Native trees will be planted following completion of Phase 2 work.
