Final Supplemental Environmental Impact Statement Public Health Service Hospital, The Presidio of San Francisco, CA This document provides new analysis, information, and changes made in response to public comments on the Draft Supplemental Environmental Impact Statement (SEIS) for the Public Health Service Hospital (PHSH), which was circulated and filed in August 2004. This document, together with the accompanying Response to Comments, will be filed as the Final SEIS. The Final SEIS is a supplement to and tiers from the 2002 Final EIS for the Presidio Trust Management Plan (PTMP), the Presidio Trust’s comprehensive land use plan and policy framework for Area B of the Presidio. The PTMP evaluated in the 2002 Final EIS included planning guidelines for the PHSH district. LEAD AGENCY The Presidio Trust (Trust), a federal corporation and executive agency created by Congress in 1996, is the lead agency for the proposed action under the National Environmental Policy Act (NEPA). The Trust maintains jurisdiction over the interior 80 percent of the Presidio of San Francisco (Area B), while the National Park Service has jurisdiction over the coastal areas of the former army post (Area A). The Trust must preserve and enhance the Presidio and also become financially self-sufficient by the year 2013. ABSTRACT The Trust is proposing to rehabilitate and reuse buildings within the PHSH district of the Presidio, to re-introduce residential uses to the district, and to undertake related site improvements. These actions represent the “proposed action” evaluated in this Final SEIS. The Final SEIS evaluates five alternatives, including a publicly requested “no action” alternative and the PTMP baseline alternative. The alternatives propose different treatments for the main hospital (Building 1801) and different amounts of demolition and replacement construction within the project site. Potential impacts associated with each alternative are described, together with mitigation measures that would reduce or eliminate those impacts. NEXT STEPS The Trust will circulate this Final SEIS for at least 30 days before making a decision on the proposed action. The Trust Board of Directors will hold a public meeting on June 15, 2006 beginning at 6:30 PM, at the Golden Gate Club, 135 Fisher Loop in the Presidio, to introduce the proposed action. Although there is no requirement for the Trust to respond to comments received on the Final SEIS, the Trust will consider all comments received during the 30-day circulation period before making the final decision on the proposed action. The Trust will determine whether the Final SEIS meets the standards for EIS adequacy under the NEPA, the Council on Environmental Quality (CEQ) NEPA Regulations, and its own NEPA regulations (36 CFR 1010), and will make a final decision on the proposed action in a Record of Decision (ROD). The ROD will be a written public record explaining why the Trust has taken a particular course of action and will enable the Trust to move forward to implement the proposed action.

and the Presidio Trust Management Plan (PTMP),1 the Presidio Trust (Trust) is proposing to rehabilitate and reuse buildings within the Public Health Service Hospital (PHSH) district of the Presidio, to re-introduce residential uses to the district, and to undertake related site improvements. These actions represent the “proposed action” evaluated in this Final Supplemental Environmental Impact Statement (SEIS). The proposed action is intended to address the Trust’s statutory requirements and the agency’s mission, which is to preserve and enhance the cultural, natural, scenic, and recreational resources of the Presidio for public use in perpetuity while making the Presidio financially sustainable. PURPOSE The purpose of the proposed PHSH project is 1) to rehabilitate and reactivate the severely deteriorated historic buildings within the PHSH district, particularly the main hospital building; 2) to protect the National Historic Landmark District (NHLD) and other historic and cultural resources; 3) to address the health and safety risks to the Presidio and surrounding city neighborhoods from dilapidated and largely vacant buildings within the project site; 4) to improve the unsightly appearance of the existing unimproved landscapes within the project boundary; and 5) to generate revenue for the long-term enhancement of these and other Presidio resources, and for ongoing operation of the Presidio as a national park site. The Trust has identified six leasing objectives for the project, and expressed the desire that these objectives be met in balance with one another.
