Peralta Creek Tree Management

Alameda County Flood Control and Water Conservation District (District) has completed a tree assessment along Peralta Creek between Davis Street and School Street.  A location map is provided for reference.  The assessment was 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 report is provided for reference.

A survey has been conducted to determine which trees are actually on District property or easement.  The District has no jurisdiction over trees on private properties.

The District will be conducting tree pruning and removal work within the District property and/or easement.  Phase 1 work will occur between Brookdale Avenue and Berlin Way and is anticipated to begin in late November/early December.  Phase 2 work will occur between Davis Street and Brookdale Avenue and is anticipated to begin sometime in 2022 pending receipt of a regulatory permit from the California Department of Fish and Wildlife.
