Geologic Hazard Abatement District No. 1990-01 (GHAd) Boundary

The City of San Ramon formed the GHAD in July 1990 and originally it included the West Branch area, located at Crow Canyon Road and Dougherty Road. During Fiscal Year 1997/98, the Board of Directors approved the annexation of the Dougherty Valley into the GHAD. In  FY 2007/08 the Board of Directors approved the annexation of the Old Ranch Summit into the GHAD.

GHAd engineer's report

Annually, the Board adopts a budget for services required to maintain and monitor the GHAD. These include the preventing, mitigating, abating, and controlling of geologic hazards. All property owners within both West Branch, Dougherty Valley, and Old Ranch Summit pay an annual assessment.

Each fiscal year, the District Engineer prepares an Engineer’s Report which includes the budget for the GHAD for that year. The annual budget for the District consists of regular site monitoring, annual inspections by a geologist or geotechnical engineer, contract services for annual mitigation and repairs, and administrative costs. In addition to paying for the annual expenditures of the District, funds collected through this assessment are placed into a dedicated reserve fund. The reserve fund is set aside to be used to mitigate and repair large, geologic hazards, such as landslides.
