Hazardous Materials Management in Soil, Hawk Hill, Marin Headlands

Golden Gate National Recreation Area » Hazardous Materials Management in Soil, Hawk Hill, Marin Headlands » Document List

Located within five miles of the Golden Gate Bridge, the Presidio, Sausalito, and Fort Baker, Hawk Hill lies within the popular Conzelman road scenic overlook corridor. This former military road lies overlooking the north end of the Golden Gate Bridge in the Marin Headlands Unit of Golden Gate National Recreation Area. It is accessible via car, bicycle, or on foot, and attracts locals and visitors from all over the world.

The National Park Service (NPS) is currently planning phase three of the Hawk Hill Visitor Improvement project. This phase will rehabilitate historic structures, expand educational opportunities through enhanced wayfinding and interpretive materials, improve
sustainability and accessibility of overlooks and seating, and protect natural and cultural resources.

During planning for Phase 3, NPS will evaluate options for cleanup of hazardous materials and soil contamination at the site, which remain from its former active military period. Site cleanup activities being considered will protect site workers and visitors and provide protection for unique habitat which supports a wide array of wildlife, including the endangered Mission blue butterfly.

The NPS is committed to encouraging public participation and providing opportunities for communication between the park and the affected community, interested stakeholders, and community residents during the environmental investigation and cleanup activities at the site. The NPS has issued a Community Involvement Plan (CIP), in compliance with the federal Comprehensive Environmental Response Compensation and Liability Act (CERCLA) as a public reference to describe the CERCLA process and activities that NPS plans to undertake for community involvement.

The CIP is one of the documents included in the Administrative Record for the Hawk Hill CERCLA process. The Administrative Record contains all information used by the NPS to make its decision on the selection of a cleanup action for Hawk Hill. The Administrative Record, including the CIP, is available by clicking on the Document List of the Project Links menu to the left. Some documents which are part of the Administrative Record will not be posted in the online information repository, but will be available by request. Requests for documents should be sent to

The National Park Service will exercise response authority by developing an Engineering Evaluation/Cost Analysis (EE/CA) to be completed by Spring 2021. This process will solicit stakeholder feedback, develop site risk analysis, and establish the criteria for determining the appropriateness of various mitigation options. Additional information will be made available on this site when stakeholder review is requested. To learn more about the CERCLA process, go to
