The Santa Clara County Parks and Recreation Department (County Parks Department) is in the process of preparing a Master Plan Amendment for Joseph D. Grant County Park. Located near Mount Hamilton on the east side of the Diablo Range, Joseph D. Grant County Park (Park) is the largest county park or recreation area in the county park system. The 2012 acquisition of the 1,155-acre Sulphur Springs Ranch property southeast of the existing park boundaries expanded the overall acreage of the park to just under 11,000 acres. The Park provides 51 miles of hiking trails (with 46 of the total 51 miles also open to equestrians and 41 of the 51 miles open to mountain bikes), offers several campgrounds, and serves as the setting for adventure races as well as astronomy, historic interpretive, and other events.
Why the County Parks Department preparing the Master Plan Amendment?

The existing Park Master Plan was approved in 1993, several decades before the acquisition of the Sulphur Springs Ranch property. The Master Plan Amendment will provide planning recommendations to facilitate opening the Sulphur Springs Ranch area, including identifying areas for public use, such as trails, service roads, parking, staging, and backpack camping. 

As part of the Master Plan Amendment process, the County Parks Department will:

  • Analyze various locations within the Park for the possibility of providing backpack camping;
  • Analyze establishing a pilot location within the Park for composting or vault toilets and potential location(s);
  • Consider biological, historic, and cultural resources that are present in the Park;
  • Meet with various stakeholders, agency staff, and the County Parks and Recreation Commission; and
  • Conduct public meetings.

Current Status
The County Parks Department presented the Master Plan Amendment’s draft recommendations to the County of Santa Clara Parks and Recreation Commission on:

Wednesday, October 2, 2019
Board of Supervisors’ Chambers
County Government Center – 70 West Hedding Street, 1st Floor
San Jose, CA 95110

Compliance with the California Environmental Quality Act (CEQA)

During the planning process, the County Parks Department will consider the Master Plan Amendment for compliance with the California Environmental Quality Act (CEQA). Once preferred recommendations are selected, a Project Description will be developed, and the environmental review phase of the project can begin, including public review and comment.
