Project Description

The proposed trail expansion area is located northeast, west and east of the existing Hidden Falls Regional Park, and south of the Bear River in Placer County. The Project area is approximately 40 miles northeast of Sacramento. The existing Hidden Falls Regional Park area encompasses approximately 1,200 acres, and includes a parking area at Mears Place, as well as an already-permitted future parking area located off of Garden Bar Road.

The proposed expansion areas to the northeast of the existing park consist of the areas known as Taylor Ranch (321 acres) and Harvego Bear River Preserve (1,773 acres), as well as privately-owned parcels with trail easements, such as the Liberty Ranch (313 acres). The trails will also cross the Kotomyan Preserve (160 acres) and the Outman Big Hill Preserve (80 acres). These areas are owned by the Placer Land Trust and are to be held as conservation land in perpetuity. Entry to these areas is currently limited to guided tours led by the Placer Land Trust. Placer County has trail easement rights within these properties. The proposed expansion area also includes a 40-acre County-owned parcel off of Garden Bar Road, as well as County-owned connectivity properties and an easement between the existing Hidden Falls Regional Park and Taylor Ranch, and a 50-acre property located off of Bell Road (Twilight Ride property). All totaled, the proposed expansion area includes approximately 2,765 acres. The County has applied for a modification of the existing Hidden Falls Regional Park Conditional Use Permit which would encompass both the existing park and the Trail Expansion areas.

An NOP was previously issued for the Project, inviting comment from January 31, 2017 through March 1, 2017. A Revised NOP was released from June 5, 2018 through July 6, 2018 because the project description had been amended to reflect the potential use of 50 acres located at 5345 Bell Road in Auburn (APNs 026-110-012 and 018) (the "Twilight Ride property") for additional trailhead parking (approximately 100 auto and 40 horse trailer spaces), as well as potential horse-boarding and concessions. Horse-boarding and concessions have since been removed from the Project Description. The Draft Subsequent Environmental Impact Report (Draft SEIR) was released for a 90-day public review and comment period from February 20, 2020 through May 20, 2020.

The Final SEIR was released for public review and comment on September 4, 2020.  The SEIR analyzed full build-out of the Project, as well as three Alternatives, which all provided various versions of a smaller project. The full build-out of the project would provide a total of 297 new automobile spaces and 68 equestrian spaces.  The County is recommending a “Reduced Project”, which is a smaller version of Alternative 2, and would reduce the parking spaces proposed with the full-build out by approximately 60 percent.  The parking areas for the “Reduced Project” would consist of the following:

  • Garden Bar 40 – Phases 1A and 1C – 25 total permanent automobile parking spaces and a separate 5 space ADA parking lot for use on weekends, holidays, and peak days, and allowance for 6 Special Events per year 
  • Mears – Existing parking plus 25 new overflow spaces
  • Twilight Ride – Phase 1 (54 auto/20 equestrian parking spaces)
  • Harvego Preserve – Limit public use to only Placer Land Trust (PLT) docent-led tours as currently allowed by PLT’s agreement for road access from the landowner (currently a maximum of 12 per year). Eighteen existing parking spaces in an existing graveled area, no new parking development or amenities associated with the parking area
  • Trails, bridges, and other amenities outside of parking areas would be as proposed within the SEIR Project Description
