Wind Farms Threaten Anza-Borrego Desert State Park

Protecting California’s Anza-Borrego Desert State Park is not as simple as it sounds. Occasionally issues arise that pull the attention away from the day-to-day work of supporting the Park, and require people to defend the space they have designated to be untouched, reports the Anza Borrego Foundation (ABF).

The proposed Ocotillo Wind Energy Facility consists of the construction, operation, and maintenance of wind turbines and associated facilities to generate up to 465 mw of electrical energy directly adjacent to Anza-Borrego Desert State Park, within the vicinity of the community of Ocotillo. A proposed total of 155 wind turbines, which would power up to 140,000 homes—each up to 425 feet tall—and up to 42 miles of access roads would be located on 12,436 acres. The project would be located contiguous with the southwestern border of Anza-Borrego Desert State Park, straddling Highway S-2.

Potential Visual Impact

The Anza Borrego Foundation has created two images of how the proposed wind farm would appear (see below).

It’s More than the Park Views that is Threatened

Impacts to natural resources of Anza-Borrego Desert State Park include:

  • Disruption of wildlife corridors for desert bighorn sheep
  • Adverse effects to golden eagles due to the birds striking the turbines
  • Adverse impacts to burrowing owls, long-eared owls, Vaux’s swift, peregrine falcons, flat-tailed horned lizards, barefoot geckos, Red diamond rattlesnakes, American badgers, and several listed plant species
  • Could cause significant deaths of bats due to the drop in air pressure causing internal hemorrhaging in the lungs as well as deaths from direct strikes
  • Unavoidable impact to plants during construction and the introduction of invasive plant species
  • Permanent scarring to the landscape leaving an “industrial” look to the area

Impacts to cultural resources of Anza-Borrego Desert State Park include:

  • Visual impacts to the newly designated Cultural Preserve at Piedras Grandes, just west of Ocotillo and its “sacred site”
  • No adequate accounting for impacts to the multiple cultural resources of the area when viewed as a cultural landscape
  • Cultural Studies not completed prior to assessing impacts

Other potential impacts include:

  • Substantial increase in noise levels from the operation of the turbines, especially at night in surrounding areas
  • Impacts to air quality from truck traffic and from concrete batch plants
  • Increased risk of wildfire hazards
  • Loss of soil’s ability to absorb carbon from scraping
  • Degradation to the recreational and natural experience of Anza-Borrego Desert State Park by the sight of the turbines and associated facilities
  • Loss of dark night skies
  • Degradation of wilderness character of the several BLM wildernesses surrounding the proposed project
