The purpose of this study is to identify the problem in Bolinas Lagoon, identify the opportunities for restoration and constraints to project development, develop planning objectives for the study, and develop a solution that addresses those planning objectives. The overall goal of the project is to find viable alternatives that provide long term benefits to the lagoon ecosystem while minimizing adverse, short term impacts. 2.0 Measures and Alternatives Considered Restoration measures considered in this study include wet sediment dredging and dry sediment excavation activities in the North Basin, Main Channel, Pine Gulch Creek Delta, Kent Island, Bolinas Channel, Highway One Fill Areas, South Lagoon Channel, Dipsea Road and Seadrift Lagoon. These measures were geographically grouped into North, Central and South. The Central and South alternatives were modified to include other variations, resulting in two alternatives for both. When these alternatives were combined to make alternative plans, all possible combinations were considered and then screened according to the evaluation criteria developed during the planning process. The final array of alternative plans included twelve different combinations of the above restoration measures. The National Ecosystem Restoration (NER) Plan is the North, Central (Estuarine) and South (No Seadrift) alternative plan and the Locally Preferred Plan (LPP) is the North, Central (Riparian) and South (No Seadrift) alternative plan. Both plans are comprehensive restoration plans addressing all areas of the lagoon, and only differ with respect to excavation in Pine Gulch Creek Delta. The Estuarine plan removes 7 of 17 acres of riparian habitat, whereas the Riparian plan removes no riparian habitat. Because the Recommended Plan will not be identified until the Final Feasibility Report, the public will have the opportunity to comment on the NER Plan and the LPP and make suggestions for further refinement. i A watershed study, the Bolinas Lagoon Watershed Study: Input Sediment Budget (2001) in Appendix A of the Environmental Impact Statement/Environmental Impact Report (EIS/EIR), was conducted during the Feasibility Study to identify sources of sediment and potential areas for sediment control and/or restoration in the watershed. The results of the study concluded that, although historical land management practices had been the cause of increased sedimentation in the lagoon in the past, the watershed is in the process of healing due to better land management practices, and there are few places where restoration would be advisable at this time. Future watershed activities will be coordinated by a Bolinas Lagoon Watershed Council, individual property owners, or others. The environmental impacts will be beneficial in the long term, although there will be some unavoidable adverse impacts in the short term, such as an increase in turbidity and noise disturbance during construction. Monitoring and adaptive management, which will be conducted before, during and after construction, will inform the implementation process and help reduce unexpected impacts. The removal of sediment in Bolinas Lagoon will improve the quantity and quality of subtidal and intertidal habitat for the diverse groups of species that rely on Bolinas Lagoon, including a variety of threatened, endangered, rare and special status species. 3.0 Recommendations The NER Plan includes the North Basin, Main Channel, Bolinas Channel, Kent Island, Pine Gulch Creek Delta: Estuarine Option, Highway One Fills, Dipsea Road and South Lagoon Channel components. The total project first cost of the NER Plan is $101,553,000. Cost sharing for ecosystem restoration projects is 65% Federal and 35% non-Federal (local sponsor), for a total of $66,009,450 Federal and $35,543,550 non- Federal. The LPP includes the North Basin, Main Channel, Bolinas Channel, Kent Island, Pine Gulch Creek Delta: Riparian Option, Highway One Fills, Dipsea Road and South Lagoon Channel components. The LPP Plan has a total project first cost of $100,716,000. Cost sharing for ecosystem restoration projects is 65% Federal and 35% non-Federal (local sponsor), for a total of $65,465,400 Federal and $35,250,600 non- Federal. For either plan, the costs associated with the Lands, Easements, Rights-of-Way, Relocations and Disposal Areas (LERRD), which would be paid for in full by the local sponsor as part of their 35% share, are expected to be minimal. The entire non-Federal cost share would be financed in cash. Based on continuing coordination with the local sponsor, results of the public review and public involvement process, and continuing refined evaluation of the ecosystem restoration alternatives, a Recommended Plan will be identified in the Final Feasibility Report. ii Commonly Used Acronyms ACR Audubon Canyon Ranch ASA(CW) Assistant Secretary of the Army for Civil Works BLTAC Bolinas Lagoon Technical Advisory Committee CEQA California Environmental Quality Act DFG Department of Fish and Game EQ Environmental Quality EIR Environmental Impact Report EIS Environmental Impact Statement EPA Environmental Protection Agency FCSA Feasibility Cost Sharing Agreement GFNMS Gulf of the Farallones National Marine Sanctuary GGNRA Golden Gate National Recreation Area GIS Geographical Information System HAAF Hamilton Army Air Field HEEP Habitat Evaluation Expert Panel HEP Habitat Evaluation Procedures HQUSACE Headquarters, US Army Corps of Engineers ICA Incremental Cost Analysis IDC Interest During Construction LERRD Lands, Easements, Rights-of-Way, Relocations and Disposal Areas LPP Locally Preferred Plan MCOSD Marin County Open Space District MHW Mean High Water MLLW Mean Lower Low Water MSL Mean Sea Level NED National Economic Development x NER National Ecosystem Restoration NER Plan National Ecosystem Restoration Plan NEPA National Environmental Policy Act NMFS National Marine Fisheries Service O&M Operations & Maintenance OMB Office of Management and Budget OMRR&R Operation, Maintenance, Repair, Replacement and Rehabilitation OSE Other Social Effects PCA Project Cooperation Agreement PED Pre-construction, Engineering and Design PMP Project Management Plan PRBO Point Reyes Bird Observatory PRNS Point Reyes National Seashore RED Regional Economic Development RWQCB Regional Water Quality Control Board SFDODS San Francisco Deep Ocean Disposal Site SLC State Lands Commission SPD South Pacific Division, US Army Corps of Engineers SPN San Francisco District, US Army Corps of Engineers USGS United States Geological Survey USFWS United States Fish & Wildlife Service WRDA Water Resources Development Act xi Bolinas Lagoon Ecosystem Restoration Project Draft Feasibility Report 1.0 INTRODUCTION This chapter provides basic background for the Bolinas Lagoon Ecosystem Restoration Feasibility Study, which is a study that has been cost shared by the U.S. Army Corps of Engineers (Corps) and Marin County Open Space District (MCOSD). It lists the steps in the Corps planning process, and relates them to the organization of this report. 1.1 Study Authority It was resolved by the Committee on Transportation and Infrastructure of the United States House of Representatives on March 7, 1996 that the Secretary of the Army review the report of the Chief of Engineers, Channel to Bolinas, California, published as House Document 537, Sixty-fourth Congress First Session, and other pertinent reports, to determine whether modifications of the recommendations contained therein are advisable at the present time in the interest of ecosystem protection, enhancement, and restoration and related purposes at Bolinas Lagoon, California. The Federal objective of project planning is defined in the Economic and Environmental Principles and Guidelines for Water and Related Land Resources Implementation Studies (P&G) approved in April 2000. Guidance for conducting U.S. Army Corps of Engineers’ civil works planning studies is presented in the revised Engineering Regulation 1105-2-100, Planning Guidance Notebook, dated April 22, 2000. 1.2 Study Purpose and Scope The purpose of Civil Works ecosystem restoration activities is to restore significant ecosystem function, structure, and dynamic processes that have been degraded. Ecosystem restoration efforts involve a comprehensive examination of the problems contributing to the system degradation, and the development of alternative means for their solution.

Lankins Senior Seminar Paper June 3, 2009 2 Eighty six years after Spain had claimed the New World for themselves an English Privateer by the name of Francis Drake was becoming a thorn in their side. Called El Draque by the Spaniards, they hated to see him in their ports. His enthusiasm for damaging Spain overseas may have arisen from a hatred by Protestants of Catholics in Elizabethan England, or from his voyage to Nombre de Dios in 1572 where he lost two brothers, John and Joeseph1. After years of terrorizing the Spanish in the Caribbean, in 1577 Drake left England for the South Sea, now known as the Pacific Ocean. It is unclear as to the exact reason for the voyage.

  • Bolinas Lagoon Is One of Marin County's Most Significant Natural
    "The lagoon is one of Marin County's most significant natural resources. The lagoon tidelands are publicly-owned. ... Along with Drake's Estero and Tomales Bay, Bolinas Lagoon provides an important coastal environment for fish, birds and mammals that is unparalleled along the northern California coast between San Francisco and Humboldt Bays. Open water, mudflat and marsh provide productive and diverse habitats for marine fishes, waterbirds, and marine mammals. Bolinas Lagoon is part of a much larger protected natural habitat complex that is part of or adjoins the Gulf of the Farallones National Marine Sanctuary (GFNMS, Pt. Reyes National Seashore, Golden Gate National Recreation Area, Central California Coast Biosphere Preserve, Mt. Tamalpais State Park, and the Audubon Canyon Ranch Bird Sanctuary." Bolinas Lagoon. Located in California, less than 20 kilometers up the coast from San Francisco’s Golden Gate Bridge, Bolinas Lagoon is a tidal embayment of open water, mudflat, and marsh which provides productive and diverse habitats for marine fishes, waterbirds, and marine mammals, and it is also part of a much larger protected natural habitat complex in the region. The site is located on the Pacific Flyway, which makes the Lagoon an ideal staging ground and stopover site for migratory birds, and the temperate climate provides wintering habitat for a wide array of ducks, geese, and shorebirds. The area supports a number of recreational uses, including the use of manually-powered watercraft. Bolinas Lagoon Open Space Preserve Marin County Open Space District Bolinas Lagoon is one of Marin County’s most significant natural resources. Its 1,100 acres, known as the Bolinas Lagoon Open Space Preserve and managed by the Marin County Open Space District, was designated a Wetland of International Importance by the Ramsar Convention in 1998.

Federal, state and local parklands abutting the Pacific Ocean provide a retreat from the hustle and bustle of Bay Area living. Coastal bluffs, beaches, wetlands, and more draw millions of international visitors for surfing, birding, kayaking, hiking, picnicking and more. Protected ranchlands are stewarded by multi-generation family farming operations which feed the region with milk, cheese, yogurt, butter, ice- cream and other products. Nestled within these vast swaths of open space are small but mighty communities that serve as both visitor hubs and homes to residents who cherish and value the unique sense of place. Climate change presents unprecedented threats to West Marin. Wetlands and beaches could be drowned with rising waters, and native plants and animal populations could plummet from changes in temperature and precipitation, ocean acidification, invasive species, and more. Coastal flooding and erosion threaten homes, roads, and utilities that are critical to the long- term sustainability of West Marin. Spearheaded by the Marin County Community Development Agency in 2014, Collaboration: Sea Level Rise Adaptation Response Team (C-SMART) is a partnership based community planning approach to solve some of these challenges. The Marin Ocean Coast Sea Level Rise Vulnerability Assessment analyzed the vulnerabilities of natural and built assets from near- to long-term combined sea level rise and storm scenarios.

The lagoon is situated along the San Andreas Fault and enclosed by a curving sand spit along its southern shoreline. The lagoon is a designated Wetland of International Importance due to its location along the Pacific Flyway and its unique habitats. The lagoon is part of the Greater Farallones National Marine Sanctuary (GFNMS) and provides a diverse mix of channel, mudflat, marsh, and riparian habitat for many shorebirds, waterfowl, fish, marine mammals, invertebrates, and special status plants and animals. The lagoon’s long history of human impacts is described in the Bolinas Lagoon Ecosystem Restoration Project (BLERP) Recommendations for Restoration and Management report (GFNMS 2008). Historical logging, farming, grazing, land use changes, lagoon dredging and fill, channelization of creeks, road construction, and hardening of the lagoon edge have led to degradation of natural hydrologic and geomorphic processes. These changes also affected patterns of sedimentation in the lagoon and disconnected estuarine and marsh habitats with riverine corridors and adjacent upland areas. Hardening of the shoreline has impacted tidal-terrestrial transition zones which limits the ability of the lagoon and its tidal habitats to expand landward and migrate upslope in response to sea level rise.
