PROJECT PROFILE Point Bonita Lighthouse Bridge WJE HAER Documentation | Marin County, CA CLIENT The site of the Point Bonita Lighthouse is continually buffeted by strong winds and salty ocean fog. National Park Service (NPS) In 2006, the severe exposure necessitated major rehabilitation of the bridge’s timber framing and steel suspension cables, and in 2010, the NPS decided to replace the bridge with a more durable BACKGROUND structure. As a contributing element to the Point Bonita Historic District and the lighthouse, which The Point Bonita Lighthouse and is on the National Register of Historic Places, the NPS required documentation of the bridge under Fog Signal buildings are critical to Section 106 of the NHPA prior to dismantling the bridge. marine navigation through the hazards of the Golden Gate.

Contractor AIS Construction (defunct) Other participating companies Yeh and Associates, Inc. Initial situation In 1954, the U.S. Coast Guard built a suspension footbridge to access the Point Bonita Lighthouse on the outer northwestern point overlooking the Pacific Ocean and San Francisco Bay. Over the years, the bridge had been renovated, but needed to be replaced in 2012. Before a new bridge could be constructed, the rock face needed to be stabilized. The point’s rock mass was fracturing and displaying signs of instability due to years of exposure to harsh marine elements. Stabilization was required to support the weight of a modern bridge without fracturing further. Description A stainless steel anchored SPIDER S4-230 mesh system was installed to stabilize the rock face. The diamond shaped net is comprised of three 4 mm wires twisted into a 1x3 strand, with tensile strength of 239 ksi and a diameter of 5/16 inches. As required by the National Park Service, the net was powder coated bronze to better blend with the natural color of the rock mass and further protect against corrosion. The project won ENR California’s Best Small Project — Construction award in 2012.

Building 201, Fort Mason, San Francisco, CA 94123 (415) 561-3000 2 011 Report to the Community
Building 201, Fort Mason, San Francisco, CA 94123 (415) 561-3000 www.parksconservancy.org 2 011 report to the community Golden Gate National Parks Conservancy dear park friends and supporters, Ten years ago, we celebrated the transformation of an old military airfield into a beloved national park. At the heart and soul of the Golden Gate National Parks, Crissy Field was created through the visionary leadership of the Evelyn and Walter Haas, Jr. Fund, the community members who contributed volunteer time and generous donations, and the efforts of the Golden Gate National Parks Conservancy in support of the National Park Service (NPS). Since its grand reopening on May 6, 2001, that spectacular shoreline park has repaid us with billions of Mark Buell Greg Moore memories—made, kept, and cherished by 10 million visitors to Crissy Field. On the pages of our 2011 Report to the Community, you’ll meet just a few of them—and see the indelible impact, drawn across their smiles, of these wondrous parklands. By the beaming faces of visitors, volunteers, and staff, we are constantly reinvigorated to work on behalf of these parks, alongside our partners the NPS and Presidio Trust. By the growing diversity of our park community, we draw inspiration to ensure these natural, cultural, and historic resources are accessible to all. And by the contributions of our 12,750 members and the support of our park friends, we fulfill our mission of Parks For All Forever. In this report, we highlight our projects and programs at Crissy Field, Lands End, and Mori Point; along Redwood Creek; on Alcatraz; and throughout the Presidio and the Marin Headlands—among many more accomplishments across 80,600 acres of national parkland.

Light Station Journal
Point Arena Lighthouse Keepers, Inc. Light Station Journal Winter 2015 New Lighthouse Logo The cover of this issue of the Light Station Journal features the new logo of the Point Arena Lighthouse. This new logo was the brainchild of former Executive Director Ty Moore before he left the Lighthouse. Ty contracted with graphic artist Dave Chapple of Chapple Design in Los Angeles to create it. Ty’s direction to Dave was to create a logo that would be very modern and yet evocative of all the things the Lighthouse represents – historical, iconic, unique, scenic, oceanic, exhilarating, world class – and be a “brand,” like the Nike “swoosh” or Coca-Cola script. The new logo may not initially appear to have a Lighthouse as part of its design, but in actuality it does have it as a main element. The vertical point and line are the cartography symbol for a light, and that symbol can be seen on charts and maps indicating there is a Lighthouse at that location. The stylized sweep that makes the logo appear to be the letter “A” is meant to evoke both the winds that are a big part of the peninsula where the Lighthouse stands and the waves that crash on its shoreline. The brass colored shading of the logo pays homage to the use of brass for the frame of the original First Order Fresnel lens in our Museum, and the use of brass in many marine applications and buildings. Cartography Symbols The new logo will appear on all Point Arena Lighthouse Keepers, Inc. (PALKI) stationary, publicity, business cards and employee apparel starting in March.

This Year Marks the Parks Conservancy's 25Th Year, and We
This year marks the Parks Conservancy’s 25th year, and we are very excited to celebrate this significant milestone—a quarter century of supporting these national parks. Together with our public agency partners, the National Park Service and the Presidio Trust, we have collaborated across the Golden Gate National Parks to ensure these treasured places are enjoyed in the present and preserved for the future. Whether a new park bench, a restored trail, a landscape rejuvenated with native plants, the restoration of Crissy Field, or the ongoing transformation of the Presidio from former military post to national park for all, the Parks Conservancy’s achievements have lasting benefits for the natural places and historic landmarks on our doorstep. Our accomplishments result from diligent efforts to connect people to the parks in meaningful ways. We have record numbers of volunteers involved in the parks, innovative and inspiring youth programs at Crissy Field Center and beyond, and unique opportunities for locals and visitors to experience the fascinating history and majestic beauty of these places. Most importantly, we have established a dedicated community of members, donors, volunteers, and friends—people who are invested in the future of our parks. With your support, we contributed more than $10 million in aid to the parks this year. Our cumulative support over 25 years now exceeds $100 million—one of the highest levels of support provided by a nonprofit park partner to a national park in the United States. On this 25th anniversary, we extend our warmest thanks to everyone who has helped us along the way.

A Peek Inside California's Radar Network
A Peek Inside California’s Radar Network The HF Radar team at San Francisco State University’s Romberg Tiburon Center face variety, beauty & sometimes danger all in a day’s work Contributed by Jim Pettigrew, SFSU RTC hrough California voter-approved bond funding, the Coastal Ocean TCurrents Monitoring Program (COCMP) was established to measure coastal surface circulation along the whole California Coast. Initially started in 2005, COCMP is now an array of nearly 60 CODAR SeaSondes covering the whole coastal region from the Oregon border south to the Mexican border. In order to provide complete coverage, and also to offer higher resolution in areas of high potential impact from buoyant discharges in regions with high population, the network is designed as COCMP SF Bay - Gulf of Farralones Node Personnel shown (left to right): Toby “nested” with standard and high resolution systems embedded within the Garfield, Chris Raleigh, Jim Pettigrew, Max Hubbard, Matt Gough broader Long-Range coverage area. The entire coast is mapped with an array of nine Long-Range (5 MHz) systems to provide 6 km resolution of surface currents from the shore out about 180 km. Between Bodega and Big Sur and in the Southern California Bight, arrays of standard range systems operating at 12 and 25 MHz provide 3 km and 1 km resolution of the currents within 80 km of shore. In San Francisco Bay-- an area that is quite dynamic and at high risk for environmental incidents--an array of four 42 MHz SeaSondes offers 0.4 km spatial resolution for the currents in the central portion of the Bay.
