About the HCP

The Upper Santa Ana River Habitat Conservation Plan (Upper SAR HCP) is a collaborative effort among the water resource agencies of the Santa Ana River Watershed, in partnership with the US Fish and Wildlife Service, California Department of Fish and Wildlife, and several other government agencies and stakeholder organizations. The Upper SAR HCP will specify how species and their habitats will be protected and managed in the future and will provide the incidental take permits needed by the water resource agencies under the federal and State endangered species acts to maintain, operate, and improve their water resource infrastructure.

Covered Species

Identification of a list of species that will be “covered” by the Plan (i.e., covered by the permits and conserved and managed through the implementation of the Plan) is one of the most important early steps in HCP development. This is commonly referred to as the covered species list. The HCP will evaluate the impacts of covered activities (i.e., those activities for which take authorization is requested) on covered species and estimate the level of take expected from these covered activities. The HCP will also describe a conservation strategy to mitigate these impacts and conserve and manage these species and the habitats upon which they depend for survival. Note that the list of covered species may continue to evolve as the process of describing activities and quantifying impacts moves forward as part of HCP development.

Plan Area

The Plan Area is the area that is being evaluated during the development of the HCP. All covered activities and conservation actions (including mitigation and avoidance and minimization measures) will occur within the Plan Area. A focused Permit Area will be identified during the HCP development process to identify the specific areas where take permits from the Wildlife Agencies are issued. Criteria important for developing the Plan Area include:

  • The area in which HCP Team water resource agencies anticipate constructing and operating infrastructure in the future.
  • The area in which HCP Team water resource agencies currently conduct O&M activities.
  • Sites currently proposed to support mitigation.
  • Areas where mitigation action opportunities may occur.
  • Important topographic or hydrologic boundaries such as watersheds.
  • Covered species habitat or natural community boundaries.
  • Jurisdictional or land use boundaries.
  • The boundaries of other approved or in-process conservation plans or open space where opportunities for collaboration of mitigation activities may be present.
