Sections of Park Trail and Bay Area Ridge Trail Closed to Dog Walking

To reduce the potential for coyote/dog conflict, we’ve proactively closed large sections of the Park Trail and the Bay Area Ridge Trail to dog walking. This annual closure is temporary; we’ll reopen these trails to dog walking in fall after pupping season ends. All 24 miles of hiking trails in the Presidio are open to people.

National Environmental Policy Act (NEPA)

Learn about how we consider environmental factors in our decision-making.

The Presidio Trust considers environmental factors in our decision-making.

We are guided by the National Environmental Policy Act (NEPA) (Pub. L. 91-190, 42 U.S.C. 4321 et seq.), the Council on Environmental Quality (CEQ) Regulations (40 C.F.R. 1500-1508), and our own regulations implementing NEPA (36 CFR 1010).

Enacted in 1970, NEPA is a cornerstone of our nation’s efforts to protect the environment. It recognizes that many federal activities affect the environment and mandates that federal agencies consider the environmental impacts of their proposed actions before acting. NEPA emphasizes public involvement in government actions by requiring that the benefits and the risks associated with proposed actions be assessed and publicly disclosed.

Presidio Trust NEPA Policy

Our NEPA reviews provide information so we can make substantive decisions in accordance with our mandate.

It’s our policy to:

  • Use all practical means, consistent with our statutory authority, available resources, and national policy, to protect and enhance the quality of the human environment
  • Ensure that environmental factors and concerns are given appropriate consideration in our decisions and actions
  • Use systematic and timely approaches which will ensure the integrated use of the natural and social sciences and environmental design arts in planning and decision-making which may have an impact on the human environment
  • Develop and utilize ecological, cultural, and other environmental information in the management of the Presidio Trust Area and its natural, historic, scenic, cultural, and recreational resources pursuant to the Presidio Trust Act
  • Invite the cooperation and encourage the participation, where appropriate, of federal, state, and local authorities and the public in our planning and decision-making processes that affect the quality of the human environment
  • Minimize any possible adverse effects of our decisions and actions upon the quality of the human environment

The Compliance Process

Our NEPA compliance can take three forms: a Categorical Exclusion, an Environmental Assessment, or an Environmental Impact statement.

Categorical Exclusion (CE)

A Categorical Exclusion (CE) describes a category of actions that are expected not to have individually or cumulatively significant environmental impacts. The Trust’s regulations implementing NEPA set out our Categorical Exclusions, which were established after CEQ and public review.

A proposed action within such a category does not require further analysis and documentation in an Environmental Assessment or Environmental Impact Statement. A Categorical Exclusion can be used after determining that a proposed action falls within the categories of actions described in the CE and that there are no extraordinary circumstances indicating further environmental review is warranted.

Environmental Assessment (EA)

When a Categorical Exclusion is not appropriate and we have not determined whether the proposed action will cause significant environmental effects, then an Environmental Assessment is prepared. If, as a result of the EA, a Finding of No Significant Impact (FONSI) is made, then the NEPA review process is completed with the FONSI, including documentation of its basis in the Environmental Assessment; otherwise an EIS is prepared.

Environmental Impact Statement (EIS)​

The most intensive level of analysis is the Environmental Impact Statement, which is typically reserved for the analysis of proposed actions that are expected to result in significant environmental impacts. When an EIS is prepared, the NEPA review process is concluded when a Record of Decision (ROD) is issued.
