© Art Zendarski 2010 Presidio Trust Management Plan Main Post Update Final Supplemental Environmental Impact Statement THE PRESIDIO TRUST NOVEMBER 2010 THE PRESIDIO TRUST’S MISSION IS TO PRESERVE AND ENHANCE THE PRESIDIO AS AN ENDURING RESOURCE FOR THE AMERICAN PEOPLE “As part of the Golden Gate National Recreation Area, the Presidio’s significant natural, historic, scenic, cultural and recreational resources must be managed in a manner which is consistent with sound principles of land use planning and management, and which protects the Presidio from development and uses which would destroy the scenic beauty and historic and natural character of the area and cultural and recreational resources.” FROM THE PRESIDIO TRUST ACT (P.L.104-333) Presidio Trust Management Plan Main Post Update Final Supplemental Environmental Impact Statement 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) and supplement to the draft SEIS (supplement) for the Main Post Update to the Presidio Trust Management Plan (PTMP). The document, together with the accompanying Response to Comments, will be filed as the final SEIS. Lead Agency The Presidio Trust (Trust), a federal government corporation and executive branch agency created by Congress in 1996, is the lead agency for the action analyzed in the final SEIS under the National Environmental Policy Act (NEPA). The Trust oversees the interior 1,168 acres (Area B) of the Presidio of San Francisco (Presidio), while the National Park Service manages the 323 coastal acres (Area A) of the former military post. The Trust must preserve and enhance the Presidio as an enduring resource for the American people and be financially self-sufficient by 2013. Abstract The purpose of the Main Post Update is to implement the Presidio Trust Management Plan (PTMP) vision of the Main Post as the heart of the Presidio, to update the planning concept for the Main Post district as described in the PTMP, and to add greater detail to the planning for the Main Post than was possible when the PTMP was completed in 2002. In order to realize the PTMP vision of the Main Post, the Main Post Update responds to new opportunities and proposes a number of actions that the Trust intends to pursue. These actions include a free-standing lodge on and south of the Building 34 site, an addition to the Presidio Theatre (Building 99), an addition to the Presidio Chapel (Building 130), and an addition to link Buildings 47 and 48 and provide an entrance for the Presidio Archaeology Center’s archaeology lab and curation facilities. The Trust seeks to accomplish the following objectives through the proposed actions: reveal the Presidio’s history, welcome the public, and employ 21st century green practices. Next Steps The Trust will circulate the final SEIS for at least 30 days before making a decision on a final course of 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 wait period. 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, and will reach a decision on the 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 final action.
