- Ocean Beach Public Policy
Ocean Beach is a beach that runs along the west coast of San Francisco, California, United States, at the Pacific Ocean. It is adjacent to Golden Gate Park, the Richmond District and the Sunset District. The Great Highway runs alongside the beach, and Cliff House and the site of the former Sutro Baths sit at the northern end. The beach is a part of the Golden Gate National Recreation Area, which is administered by the National Park Service.
Over the years, the City of San Francisco and the various public agencies that have jurisdictional control over Ocean Beach have been trying to figure out how to manage this area. Previous efforts and resolutions by the Ocean Beach Task Force (2000) and Ocean Beach Vision Council (2008) did not include a pathway to implementation, and thus a new effort is underway. The new approach that is being taken with the current Ocean Beach Master Plan is to have a non-profit lead the project and incorporate all relevant agencies into the dialogue so they can then incorporate recommendations into their respective agencies.
The Ocean Beach Task Force (OBTF) was created in January 2000 by San Francisco's Mayor Willie Brown. The purpose of this task force was to address and preserve the environmental well-being of Ocean Beach as well as identify challenges and solutions for erosion, natural resources, recreation, and aesthetic issues.
The Ocean Beach Vision Council (OBVC) was created in March 2008 by San Francisco's Mayor Gavin Newsom. The purpose of the OBVC was to propose "environmentally sustainable alternatives to improve beach access, enhance underutilized resources, and reconnect Ocean Beach to the city and its international visitors."
The Ocean Beach Master Plan
The current effort to develop a comprehensive plan for this section of San Francisco, California is the Ocean Beach Master Plan (OBMP). The OBMP is an interagency effort led by the non-profit, San Francisco Planning and Urban Research Association (SPUR), to develop a long-term vision for Ocean Beach that will address a multitude of issues. Funding for this project is provided by $410,000 in government grants from the California State Coastal Conservancy, the San Francisco Public Utilities Commission, and the National Park Service. The goal of the OBMP is "to knit the unique assets and experiences of Ocean Beach into a seamless and welcoming public landscape, planning for environmental conservation, sustainable infrastructure and long-term stewardship." The OBMP also sets out to define a new approach to coastal resource management that strikes a balance between infrastructure needs, cultural, recreational, and natural-resource values, and one of the most pressing issues for modern day natural resource management: a changing climate.
The OBMP has identified seven major areas of focus to help organize and refine the complexities of such a comprehensive project. These areas include:
Project Schedule Startup (Jun-Aug 2010) Problem Definition (Sep-Dec 2010) Alternatives / Scenario Development (Jan-May 2011) Draft Master Plan (Jun-Sep 2011) Final Master Plan (Oct-Dec 2011)
While all are essential to meeting the projects far-reaching goals, SPUR has identified ecology, coastal dynamics and climate change, and infrastructure as the three main areas of focus that will help shape the policies and recommendations for the remaining categories. The final product from this planning process will essentially be a series of project and policy recommendations for the respective agencies that have control over these various focus areas. The Ocean Beach Master Plan will not have the force of regulation on its own. However, once these agencies implement these recommendations and conduct environmental reviews under the California Environmental Quality Act or the National Environmental Policy Act, then the project can take effect.
1) Image & Character
- Goal: preserve and celebrate the beach's raw and open beauty while welcoming a broader public
On January 15, 2011, the first Ocean Beach Master Plan public workshop was held at the San Francisco Zoo in an effort to inform the public about the project and to collect feedback from the community and other interested parties. One of themes that permeated the public comments was the desire to keep Ocean Beach 'natural' and maintain its wild quality. Although Ocean Beach is technically within the city limits, many visitors use this urban beach as an escape from the city. The OBMP project team has recognized this observation and aims to address the built and natural environment of Ocean Beach with landscape design that can represent this place's unique image and character.
2) Access and Connectivity
- Goal: provide seamless and fluid connections to adjacent open spaces, the city, and the region
Ocean beach is not only a popular destination in itself for beach-goers, nature lovers, and sports enthusiasts alike, but acts as an important corridor linking may of the city’s open spaces and transit ways for both residents and visitors. The Great Highway, built in the 1920s, and once the widest stretch of pavement for its length in the world, connects Sutro Baths and Lands End at the northern end of Ocean Beach to Golden Gate Park, the San Francisco Zoo and Fort Funston to the south. Narrowed in the 1990s by nearly half, the Great Highway still acts as a major artery connecting California’s historic Highway 1 to the Golden Gate Bridge. San Francisco Municipal Railway's (MUNI) transit system provides plentiful public transportation options, including the N-Judah, L-Taraval, and 38-Geary lines, which all end within easy walking distance to the beach. However, pedestrian access ways from public transit to Ocean Beach have been criticized as inadequate and oftentimes confusing. While on a normal usage day plentiful parking can be found along the beach, on hot sunny days when crowds swell parking can often be difficult, highlighting the need for improved public transport options.
A multimodal vision for the future? The City of San Francisco has recently hosted their Sunday Streets program at Ocean Beach several times, closing the Great Highway to cars and offering a full day for bicyclists, pedestrians, and skateboarders to enjoy the open space along the beach car free. The San Francisco Bicycle Coalition has also recently launched a campaign to build a bikeway from SF Bay to Ocean Beach.
- Goal: restore and establish conditions that support thriving biological communities
The beach and the dune system at Ocean Beach provide habitat for numerous species; including two birds which are listed as threatened.
The dune system spans about a mile between Great Highway and the beach; starting around the edge of Golden Gate Park and ending around Noriega Street. This ecosystem consists of predominantly non-native vegetation such as ice plant (Carpobrotus edulis) and European dune grass (Ammophila arenaria). Many participants at the first public workshop suggested restoring the dunes with native species. Although the OBMP project team will examine this proposal as a possible alternative, they predict that it will most likely be very costly.
The bank swallow is a state-listed threatened species that inhabits hollows in the bluffs at the south end of Ocean Beach (just south of the Sloat parking lot). The bank swallow colony that lives here inhabits more than one hundred burrows and is the northern most major colony on the California coast. Due to the threat of erosion, this sensitive habitat is at risk of destruction from the ocean or from the proposed coastal armoring aimed at protecting the integrity of the bluffs. In an effort to protect the bank swallows, the San Francisco Department of Public Works (SFDPW) ceases work in this area during their breeding season (April to August).
While the bank swallows occupy the southern end of Ocean Beach, the Western Snowy Plover (Charadrius alexandrinus nivosus) inhabit the central part of the beach where the sand is dry. Because Snowy Plovers (plovers) prefer the flat, sandy areas of the beach they are frequently disturbed by human recreational activities. In addition to altering their habitat, these disturbances can contribute to high rates of nest failure and chick mortality. Furthermore, frequent disturbances can disrupt caloric accumulation and result in diminished migration and breeding success. The Western Snowy Plover is a federally listed threatened species so the National Park Service (NPS) has taken measures to protect this species by limiting access to certain parts of the beach where plovers nest.
4) Program & Uses
Due to Ocean Beach's recreational opportunities, this area is utilized by a wide range of users; from surfers to bird watchers, cyclists to dog walkers. For the most part these various activities are able to share this space without conflict; however, some have inherent competing interests. For example, bird watchers and people concerned with the threatened bird species that inhabit Ocean Beach are at odds with the beach goers who bring dogs to the beach and disturb their habitat. The National Park Service issued a Draft Dog Management Plan in January 2011 to address this concern and the effects that dogs are having in the Golden Gate National Recreation Area, including Ocean Beach. Currently, the NPS does not allow dogs in the Snowy Plover Protection Area (SPPA) located at the northern end of Ocean Beach. The Draft Dog Management Plan's preferred alternative would further limit dog access as follows:
- Goal: accommodate diverse activities and users, managed for positive coexistence
- allows on leash dog walking on the trail along the Great Highway
- regulated off-leash area on the beach north of Stairwell #21
- no dogs on the beach south of Sloat Blvd.
- no dogs in the Snowy Plover Protection Area (SPPA)
5) Coastal Dynamics & Climate Change
- Goal: identify a proactive approach to coastal management, in the service of desired outcomes
For the last two hundred and fifty years, humankind’s industrial and agricultural activities have been releasing carbon dioxide (CO2) and other greenhouse gases (GHGs) into the atmosphere at ever increasing rates. Pre-industrial atmospheric CO2 concentrations of ~280 ppmv (parts per million by volume) have risen steadily to the current rate of ~388 ppmv in 2009, a level that the Earth has not experienced in at least the last 800,000 years. Industrial burning of fossil fuels, as well as cement production, automotive emissions, and deforestation practices are the main contributors to elevated CO2 emissions, each of these a result of the increasingly global industrialization of our world. As carbon dioxide and other greenhouse gas levels rise, a multitude of changes to important climate properties are expected to occur: significantly increased surface temperatures - both oceanic and atmospheric, variability in storm frequency and strength, sea-ice loss, changes in rainfall patterns and sea level rise, as well as important changes in the carbonate chemistry of the oceans. Climate change may first be apparent along vulnerable, exposed coastlines like that of San Francisco’s Ocean Beach, therefore, a comprehensive management plan that attempts to take these many factors into account is essential. The Intergovernmental Panel on Climate Change (IPCC)’s Fourth Assessment Report released in 2007 projected with “very high confidence” that coastal systems will face the following threats due to climate change:
- Coasts will be exposed to increasing risks such as coastal erosion due to climate change and sea-level rise.
- "Increases in sea-surface temperature of about 1-3 °C are projected to result in more frequent coral bleaching events and widespread mortality unless there is thermal adaptation or acclimatization by corals."
- "Many millions more people are projected to be flooded every year due to sea-level rise by the 2080s."
Seasonal and yearly beach and shoreline fluctuation is a naturally occurring process. These natural fluctuations in beach width and shape only become an erosion problem when permanent structures, such as roads, parking lots, and walkways are placed at fixed points near the beach, within this zone of fluctuation. As the shoreline recedes, roads, neighborhoods and other infrastructure will need to be protected or abandoned. The Oceanside Water Pollution Control Plant (OWPCP) and its surrounding roadways situated at the south end of Sloat Blvd. were planned and built in the 1980‘s to early 1990‘s, when the Beach at this end was naturally wide. After several years of severe storm events including major storms in both 1997 and again during the el niño winter of 2009-2010, the south end of Ocean Beach near the OWPCP began experiencing severe erosion. In 2010, bluff tops receded as much as 40 feet, undermining parking lots as well as the shoulder of the Great Highway, which ended up being closed southbound for much of the year. Underlying sewer pipes connected to the OWPCP also became threatened by erosion. In 2010 the city’s emergency response was the construction of 425 feet of rock revetments (embankments of stone riprap) along this portion of OB. Though temporarily effective, this type of emergency erosion control often draws criticism from environmentalists for causing unnecessary beach and habitat loss.
Sea-Level Rise and Increased Storm Severity
Another likely effect of climate change that may have a significant impact on Ocean Beach is sea-level rise:
- The 2007 Intergovernmental Panel on Climate Change report suggests that global average sea level may rise between 0.6 and 2 feet (7.2 inches - 24 inches) by the end of this century.
- The State of California has predicted that sea-level will rise by 16 inches by 2050 and 55 inches by 2100.
- A study released by the International Arctic Monitoring and Assessment Program (AMAP) in May 2011 predicts that sea level will rise as much as 63 inches by 2100.
Accelerated sea-level rise will likely lead to increased coastal erosion along Ocean Beach. Bluffs and beaches may be exposed to more powerful and more frequent wave action due to both elevated seas and an increase in storm frequency and severity, anther effect of climate change that has been predicted by the IPCC. Protecting the beach, dunes, and any man-made structures from the effects of erosion will require some form of erosion control measure. Currently three options for the management of erosion at Ocean Beach have been utilized or are being considered:
Coastal armoring is a protective measure that seeks to prevent erosion by placing hard structures such as seawalls or revetments (sometimes referred to as riprap) along a receding shoreline. Currently there are approximately linear 10,000 feet of hard structures at Ocean Beach, including three existing seawalls and more recently placed revetments.
Beach nourishment, or the process of replacing lost sediment within the littoral cell, is another option to counteract erosion at Ocean Beach. Beach nourishment is a potentially promising option as the US Army Corps of Engineers (USACE) currently dredge 300,000 cubic yards of sand within the San Francisco Bay annually. In 2006, USACE led a demonstration project to determine if beach nourishment is a promising solution to the erosion problem at Ocean Beach. There is currently an effort underway to retrofit the Army Corps’ dredge, the Essayons, so that it can pump sand directly onto the beach at Ocean Beach, which would help reestablish a wide beach north of Sloat Blvd. (Need CITE)
Managed retreat is the gradual removal of manmade structures that may be exposed to flooding due to an advancing coastline. This strategy is relatively simple and effective when it comes to structures such as roads or parking lots, but for several structures in the vicinity of Ocean Beach, including the publicly-funded Oceanside Wastewater Treatment Plant, managed retreat may be a much more difficult option to pursue. (Need CITE)
6) Management & Stewardship
- Goal: provide an approach to long-term stewardship across agencies, properties and jurisdictions
The management of Ocean Beach and the surrounding area has been complicated by jurisdictional issues and the oftentimes competing interests of the many stakeholders that play some role in OB governance. This list includes many local, state, and federal regulatory agencies, local businesses, and nearby residents. The creation of the current OBMP attempts to address this regulatory hodgepodge by bringing together the goals and objectives of these various agencies and constituents into one cohesive managerial plan.
One of the biggest challenges to creating a comprehensive management plan for Ocean Beach are complicated jurisdictional issues. The following federal, state and local regulatory agencies play some role in owning/managing the beach:
The National Park Service (NPS) is the owner and manager of Ocean Beach, which is completely encompassed within the Golden Gate National Recreation Area (GGNRA). Areas around Ocean Beach are managed by various city agencies, including: the Department of Public Works, which manages the roadways and other surrounding infrastructure, San Francisco Recreation and Park Department (SFRPD), which manages Golden Gate Park and the multi-use pathway bordering Ocean Beach, and the San Francisco Public Utilities Commission (SFPUC), which manages the Oceanside Water Pollution Control Plant and underground sewer lines. The shoreline falls under federal jurisdiction, and so is subject to other regulatory agencies, including the California Coastal Commission and the Army Corps of Engineers.
In addition to the regulatory agencies mentioned above, there are numerous community groups, environmental organizations, neighborhood businesses, and local residents that also act as stakeholders, ultimately having some say in any decisions that are made regarding Ocean Beach. Reconciling these various groups' goals, objectives, and oftentimes differing priorities is a complicated yet essential task that has been emphasized throughout the Ocean Beach Master Plan planning process. SPUR has compiled a Preliminary Public Feedback Summary from their January 15, 2011 Ocean Beach public input meeting; and the following are some of the various community, environmental, and neighborhood groups that have participated in the current OBMP planning process:
- Black Rock Arts Foundation
- Coalition to Save Ocean Beach/Friends of Sutro Heights
- Coastal Sediment Management Workgroup (CSMW)
- Golden Gate National Parks Conservancy
- Golden Gate Audubon Society
- Great Streets Project
- Neighborhood Parks Council
- Planning Association of the Richmond/Friends of Sutro Height
- Save the Waves Coalition
- San Francisco Bicycle Coalition
- San Francisco Zoological Society
- Surfrider Foundation
- Goal: evaluate infrastructure plans and needs in light of uncertain coastal conditions, and pursue a smart, sustainable approach
During the winter storm events in 2009/2010, the bluff area south of Sloat Blvd. experienced severe erosion which subsequently exposed and damaged infrastructure. The bluffs under the Great Highway were scoured away, resulting in parts of the road and parking lots crumbling into the ocean and a portion of the Lake Merced Wastewater Tunnel becoming exposed.
The Great Highway is a four-lane (two lanes in each direction) expressway that runs approximately 3.5 miles along Ocean Beach. The route's northern end beings at Point Lobos Ave and extends to the Skyline Blvd. at the southern end where it connects with Route 35. In January 2011, San Francisco officials ordered both southbound lanes of the Great Highway near Sloat Blvd. closed until summer due to erosion occurring along the bluffs in this area. The detour along Skyline Blvd. raises the question: can this become a permanent alternative route?
Since these erosion events are occurring every winter and climate change forecasts increased severity and frequency of winter storms, a more permanent solution needs to be implemented. Another alternative would be to reduce the number of lanes and convert the two lanes furthest away from the coast into a single lane in each direction (as per the previous recommendations set forth by the OBTF). A transportation analysis would need to be conducted by the OBMP team to determine the impacts that such a reduction in lane-use would have on traffic.
The Lake Merced Wastewater Tunnel is another piece of infrastructure in this area which has been analyzed for relocation. The tunnel is located at the southern end of Ocean Beach where the worst of the erosion is occurring. The purpose of the tunnel is to store runoff and prevent overflows during storms when large amounts of water inundate the combined sewer-stormwater system. Local officials are concerned that untreated sewage could spill onto the beach and into the ocean if the tunnel becomes compromised due to damage from erosion. The San Francisco Department of Public Works has looked into the costs of relocating the tunnel and its associated structures but the figures are costly. Moving the tunnel alone would cost an estimated $110.46 million. If the associated Southwest Ocean Outfall (SWOO) pipe and other pressurized pipes are moved as well the total cost would rise to almost $167 million. Since the relocation costs are high, alternatives that protect the pipe rather than move it are being considered and evaluated. One option would be to strengthen the tunnel/pipe from within. By thickening its inner walls, the tunnel will lose storage capacity, however it will increase structural integrity. Another option is protecting the exposed tunnel with coastal armoring.
Similar to the Lake Merced Wastewater Tunnel, the Westside Transport Box acts as storage for the Oceanside Water Pollution Control Plant when this facility's capacity is overwhelmed. The transport box is a large rectangular tube that runs under the Great Highway from Lincoln Way to Sloat Blvd. Unlike the tunnel, the transport box is not in any immediate danger from erosion. Instead this section of the City's stormwater-sewage infrastructure may become a significant factor in shaping the beach and dunes as the coastline recedes. If the coastline along Ocean Beach recedes past the current seawalls, the Westside Transport Box could act as a last line of defense to rising sea levels.
