Ocean Beach, one of the gems of the San Francisco landscape, faces significant challenges. For the past two years, SPUR has led an extensive interagency and public process to develop the Ocean Beach Master Plan, a comprehensive vision to address sea level rise, protect infrastructure, restore coastal ecosystems and improve public access.
The Ocean Beach Master Plan and Implementation Studies are made possible by the State Coastal Conservancy, the San Francisco Public Utilities Commission and the National Park Service.

SPUR and its partners kicked off the Multimodal Transportation Analysis on July 26th, making it the second in a series of three implementation studies that will help agencies analyze and move forward with recommendations made in the Ocean Beach Master Plan (OBMP). The OBMP presents a number of recommendations that would have significant transportation implications, most notably the closure of the Great Highway south of Sloat Boulevard and re-routing of traffic via Sloat and Skyline Boulevards. The analysis will include an existing conditions study, design and configuration development based on OBMP recommendations, and transportation modeling.
SPUR has been working closely with the San Francisco Municipal Transportation Agency (SFMTA) and SF Planning Department to scope this implementation study, which is funded by the California State Coastal Conservancy and National Park Service through the Golden Gate National Recreation Area (GGNRA). SPUR is pleased to announce Nelson\Nygaard and AECOM as the consultant team for this project. The two firms were instrumental in the development of the OBMP and bring expertise in transportation planning and engineering, multimodal street and intersection design, landscape design, and transportation modeling. Nelson\Nygaard is the lead consultant and will oversee the design and configuration development, while AECOM will carry out the existing conditions study and transportation modeling. These projects are elaborated upon below:
Existing Conditions Analysis
The existing conditions analysis will collect and present data relevant to OBMP recommendations, utilizing multimodal traffic counts, traffic performance analysis, and circulation conditions. Traffic counts and performance analysis will be conducted at key intersections along the Great Highway and on nearby thoroughfares--such as Sunset Boulevard--to examine the feasibility of OBMP recommendations that would divert traffic.
The analysis will provide a summary of commute and recreational travel patterns, accounting for peak usage demand during rush hour, special events, and favorable weather. This will ultimately inform the design and configuration development process, identifying potential challenges and recommendations related to the implementation of the OBMP.
Design and Configuration Development
Using the existing conditions findings, conceptual street and intersection configurations will be formulated. Three alternatives will then be selected, with preliminary designs being presented to stakeholders in at least one public workshop in Spring 2014. Design options will focus on OBMP recommendations, including removing the Great Highway south of Sloat Boulevard, the reconfiguration of Sloat Boulevard and intersection modifications, as well as addressing Zoo circulation and access planning, the L-Taraval extension, narrowing the Great Highway between Lincoln and Sloat, and parking supply and management.
Multimodal Transportation Analysis and Modeling
Next spring, SPUR will work with project partners to select and finalize three design and configuration alternatives for transportation analysis and modeling, which will help the project team identify the challenges, opportunities, and impacts associated with each.
The resulting report, which will be integrated with the SF County Transportation Authority’s citywide transportation model, will be completed according to city technical standards in preparation for eventual review under the California Environmental Quality Act.
SPUR will continue to monitor the progress and impacts of ongoing projects near Ocean Beach, including SFMTA’s Livable Streets safety improvements on Sloat Boulevard, SFPUC’s Sunset Boulevard Greenway Project, and DPW’s streetscape improvements and Great Highway repaving project.
Throughout this process, SPUR will coordinate the work of the team and agency partners, assist the project team in coordinating with other ongoing transportation studies along Ocean Beach, continue its public outreach efforts, and steward the Ocean Beach Master Plan vision.

Six months after Hurricane Sandy wreaked havoc on the northern Atlantic Coast, New York City released its plan to protect the city in what may be the most extensive climate adaptation plan to date. ‘A Stronger, More Resilient New York’ matches coastal protection strategies with the needs of New York's varied waterfront land uses. As SPUR and its partners move forward with the implementation of the Ocean Beach Master Plan, some intriguing lessons from Hurricane Sandy and New York’s new plan can be applied to San Francisco’s western shoreline.
Vision 2020 and A Stronger, More Resilient New York
Just one year prior to Hurricane Sandy, New York City issued ‘Vision 2020: New York City Comprehensive Waterfront Plan,’ a ten-year framework for waterfront development that included “strategies to increase the city’s resilience to climate change and sea level rise.” The destruction caused by Hurricane Sandy crippled the city’s infrastructure and became a catalyst for more extensive planning. As the second costliest hurricane in US history after Katrina, the storm resulted in billions of dollars in flooding damage, widespread power outages, gas shortages, subway closures, and an overwhelmed sewer system.
Building on the waterfront plan, ‘A Stronger, More Resilient New York,’ identifies coastal protection strategies including increased coastal edge elevations through the use of beach nourishment, sea walls, or bulkheads; minimizing upland wave run-up and storm surges by slowing waves before they reach the shore and through the use of levees and floodwalls; and floodproofing buildings located within FEMA’s mapped floodplains.

Performance of Nourished Beaches and Dunes
While there are dramatic differences between the coastlines of New York and San Francisco, especially in terms of population density and development intensity, New York’s ocean-facing coastline and San Francisco’s Ocean Beach have experienced massive amounts of erosion in recent storms. The 2009-10 El Niño storms caused the Ocean Beach shoreline to retreat 75% further than a typical winter, undermining the parking and road shoulder along the Great Highway and requiring a $5 million dollar emergency remediation project. Similarly, an estimated 3 million cubic yards of sand were lost citywide as a result of Hurricane Sandy.
The Rockaway Peninsula accounted for half of the city’s total sand losses, but neighborhoods protected by dune systems suffered far less damage than areas without them. Nourished beaches on the Coney Island Peninsula and Brighton Beach also performed better in comparison, absorbing wave energy and floodwater surges. Like New York’s plan, SPUR’s OBMP recommends the restoration of native dunes in key locations at Ocean Beach, along with the use of large-scale beach nourishment south of Sloat Boulevard to forestall erosion caused by prevailing sediment circulation patterns.
Unlike San Francisco’s western shoreline, New York’s developed coastline has little room to allow for retreat. In Vision 2020, retreat is only considered an option along less developed portions of the coastline, such as wetlands or other open spaces. On a large scale, retreat in the NYC area would mean displacing residents and relocation of infrastructure that would be extremely difficult and expensive to move. The report also notes that retreat would impede the city’s goals of dense development along the waterfront. Therefore, most of New York’s waterfront protection measures will involve hard engineering strategies.
However, with federally protected beaches and a four-lane highway, San Francisco’s western shoreline has more room to work with natural processes, allowing for managed retreat. At the core of the Ocean Beach Master Plan is the narrowing of the Great Highway along the length of the Sunset District and its closure south of Sloat Boulevard, allowing space for native dune restoration and the creation of a multi-modal path to improve recreational coastal access.

Learning from Hurricane Sandy
New York’s recovery from Hurricane Sandy and its recent climate change adaptation planning efforts highlight the need for implementation. Although New York had prepared the Vision 2020 waterfront plan, the hurricane caught the city largely off guard and highlighted the need for increased resiliency in power, transportation, and wastewater treatment systems.
Although San Francisco’s Bay Conservation and Development Commission has invested significantly in the Adapting to Rising Tides study and SPUR has conducted extensive research on climate adaptation, New York’s experience highlights the need to move beyond planning studies and to act.

The placement of 73,000 cubic yards of sand by SFPUC and the GGNRA -- a softer approach to coastal protection that SPUR supports -- has resulted in a significant unintended consequence: windblown sand that has closed the parking lot, restroom, and Great Highway at Sloat Boulevard. Large amounts of sand (where once there was next to none) combined with its relatively fine grain size, the ramp-like shape of the embankment that was created and especially heavy offshore Spring winds, have resulted in drifts forming higher than the concrete barriers at the parking lot's edge, creating a headache for city crews, who are struggling to keep up.
At the same time, the sand has provided a lot of benefits. It has allowed an additional measure of protection, helping to stave the placement of any additional hard structures. According to coastal engineers working in the area, it has also been moved alongshore, raising the level (and thus the width) of the sandy beach for some distance beyond the placement area. A casual observer can see that the project drastically improved aesthetics and pedestrian access to the beach, covering the exposed fill and rubble as well as portions of the nearby sandbags and revetments.
Why it Matters
Resolving the windblown sand problem is especially important for the future of coastal management at Ocean Beach. Beach nourishment (or the placement of sand) is envisioned as a major tool for tackling erosion, both through a repeat of last year's "backpass" by truck from the north end of the beach, and, longer-term, through the placement of sand dredged from the Golden Gate Marine Shipping Channel by the US Army Corps of Engineers. If the side effect of sand placement is havoc on the landside, the ability to use this tool will be compromised.
The Good News: Mitigation Techniques
The news is that there are many measures that can reduce the incidence of windblown sand. SPUR is working with our partner agencies and coastal consultants to develop and test some best practices going forward. First, the sand embankment can be reshaped to act as less of a launching ramp. Sand fencing can also be placed to interrupt blowing sand. Simple string fencing or driftwood can guide visitors to the best access points, limiting surface impacts. Straw made from dried beach grass can be 'punched' into the sand, introducing a rougher surface that inhibits blowouts.

What to Expect
Look for city crews to be removing sand in the coming weeks, followed by a pilot project testing some of these windblown sand management techniques.

The Coastal Management Framework (CMF) is a new project that sets the stage for implementation of the Ocean Beach Master Plan’s (OBMP) approach to coastal management through the year 2050 in the context of severe erosion and climate-induced sea level rise. The OBMP presents a series of recommendations designed to improve and restore conditions at Ocean Beach- including managed retreat, beach nourishment, and innovative approaches to protecting threatened infrastructure while maintaining recreational access and ecological functions. The Framework will include interim protection strategies in anticipation of extreme weather events, as well as a long-term strategy for adapting to sea level rise, and it will lay the foundation for an interagency coastal management agreement among the three major responsible agencies, San Francisco Public Utilities Commission (SFPUC), Golden Gate National Recreation Area (GGNRA) and the United States Army Corps of Engineers (USACE).
SPUR has been working closely with SFPUC and GGNRA staff to scope this project. In January, SPUR hired a team of coastal engineering consultants led by Bob Battalio at ESA PWA and Dilip Trivedi at Moffatt & Nichol. Other team members include AGS, Inc. and Jacobs Engineering, as well as coastal plant ecologist, Peter Baye. On January 31st, 2013, SPUR kicked off the CMF project with participants from the SFPUC, GGNRA, USACE, San Francisco Department of Public Works (DPW), and the consultant team.
The team’s first task will create a near-term (1-10 year) approach to coastal management. Over the next few months, the consultant team will work with SFPUC, GGNRA and USACE to investigate best practices and case studies for innovative coastal protection strategies, emphasizing options that are reversible, minimally impactful, and compatible with Ocean Beach Master Plan recommendations. The interim approach will build on recent successes using softer approaches to coastal protection, including the use of temporary sandbags and the placement of large quantities of excess sand from the north end of the beach.
The team will also identify key triggers phasing of coastal protection measures at Ocean Beach.
Over a longer time scale, the team will develop an approach to cleaning up debris and rubble south of Sloat Boulevard, as well as a managed retreat approach for gradually closing the Great Highway south of Sloat, allowing for the coastline to recede and for new restoration and recreational opportunities. This process will require careful coordination with the California Coastal Commission, as well as OBMP stakeholders, in determining the best strategy.
Coastal Engineering Feasibility Studies
The next task will result in the production of two studies, a Coastal Vulnerability Analysis Study, and a Coastal Engineering Feasibility Study, to test and develop the concepts outlined in the OBMP. The first is an expanded analysis of existing and projected coastal hazards through erosion and flooding, taking account of the complex dynamic processes that shape the coast... The second study will analyze the vulnerability of coastal infrastructure and will develop a suite of protection measures, such as managed retreat, sand placed through beach nourishment, dynamic cobble berms and low-profile structures. This effort will develop a “multi-objective” approach to coastal protection, meaning that it will address ecological, recreational, and aesthetic considerations along with engineering and cost imperatives.
Coastal Protection In-Situ Pilot Studies
The team will also recommend and design pilot studies of coastal protection measures at Ocean Beach, studying the performance and behavior of different interventions in the unique and challenging conditions there. The interplay of the underlying geology, existing and placed sand, exposed fill, and innovative tools like dynamic cobble berms needs to be better understood to support an adaptive approach to coastal management at Ocean Beach, and these studies would provide critical information.
Interagency Coastal Management Agreement
Ultimately, SPUR and its partners will produce a Coastal Management Framework Report that will provide the basis of an agreement among the SFPUC, Army Corps, and GGNRA. This agreement would include a 40-year Coastal Protection Strategy, including a strategy for Capital Planning to fund these construction projects and a strategy for moving these projects through the environmental review and permitting process.
Throughout this process, SPUR will coordinate the work of the team and agency partners, continue its public outreach efforts, and steward the Ocean Beach Master Plan vision. Keep an eye on our blog, Facebook, and Twitter for additional updates on OBMP’s Implementation Studies, including more detailed posts on the Transportation and Joint Open Space Planning projects!

For the past two years, SPUR has led an extensive interagency and public process for the development of the Ocean Beach Master Plan. This work represents the first move SPUR and San Francisco have made to directly address sea level rise. Now we are beginning the first steps to implement the plan, which presents recommendations for the management and protection of San Francisco’s Ocean Beach through the year 2050. The master plan lays out an ambitious and proactive vision to adapt to rising seas, protect infrastructure, restore coastal ecosystems and improve public access. The vision was developed through the participation of a wide range of public agencies, advocates, and citizens over an 18-month period.
Read the complete Master Plan >>
The Ocean Beach Master Plan is already achieving tangible benefits and improved partnership among public agencies. In August and September of 2012, the Golden Gate National Recreation Area (GGNRA) partnered with the San Francisco Public Utilities Commission (SFPUC) to truck 73,000 cubic yards of excess sand from the north end of Ocean Beach to the south, tackling two problems at once: the record accumulation of sand at the north end, and severe erosion at the south end. The results — a “sacrificial” dune protecting the beach and covering unsightly rubble — hint at the potential of large-scale beach nourishment, a key ingredient in the Ocean Beach Master Plan vision.
This year, the San Francisco Department of Public Works (DPW) is repaving the Great Highway from end to end. As key a partner on the master plan, DPW was well aware of the plan’s proposals to improve pedestrian and bicycle access to Ocean Beach. DPW Director Mohammed Nuru directed his staff to add recommended planted medians and improved crossings to the repaving project, which will improve safety and access while improving environmental performance and aesthetics.
SPUR Leads Implementation Studies
The Ocean Beach Master Plan is a vision document. Although it is already shaping actions on the ground, it doesn’t yet have the force of law or policy. SPUR is now engaged in efforts to implement the vision, helping to translate plan recommendations into implementable projects, develop more detailed technical analysis, and prepare for environmental and regulatory review. We have been awarded funds from the California State Coastal Conservancy, the San Francisco Public Utilities Commission and the National Park Service to conduct implementation studies. These will include a transportation analysis, a coastal management framework and open space planning.
Implementing the Ocean Beach Master Plan vision will require significant reconfiguration of roadways, including the closure of the Great Highway south of Sloat Boulevard, the re-routing of traffic behind the San Francisco Zoo via Sloat and Skyline, and the redesign of Sloat Boulevard into a multi-modal coastal gateway. This project will conduct detailed transportation analysis, including an existing conditions study, the development of roadway configurations based on Ocean Beach Master Plan recommendations, and modeling the effects of the proposed changes on the city’s transportation system.
SPUR is working closely with SF Municipal Transportation Agency and SF Planning Department staff to scope this project and ensure it will meet the city’s technical requirements.
Coastal Management Framework
The Framework will test and further develop the master plan’s approach to coastal management, which includes a combination of managed retreat, beach nourishment and coastal armoring, all designed to protect threatened infrastructure while also supporting coastal access, recreation and ecological functions. This study will include interim protection strategies, as well as defining triggers and actions as sea-level rise sets in. It will lay the foundation of an interagency agreement for adaptive coastal management actions by the three major responsible agencies (SFPUC, GGNRA and the United States Army Corps of Engineers).
SPUR is working closely with SFPUC and GGNRA staff to scope this project and hire a coastal engineering consulting team.

Joint Open Space Planning
This project will coordinate collaboration between local and federal partners in managing Ocean Beach as a recreational and ecological resource. The study will include open space schematic design and programming studies, as well as pilot studies and the installation of temporary amenities. It will lay the foundation of an interagency agreement for open space management actions by the two major responsible agencies, GGNRA and the SF Department of Recreation and Parks).

California’s changing coastline is urging resource managers to plan for the immediate and long-term impacts of climate change on their local ecosystems and infrastructure. With no single lead agency planning for climate change, collaboration among governmental agencies, NGO’s, academic institutions, and communities is integral to plan for coastal adaptation measures. The Bay area is home to several citizen-based organizations and agencies working towards these efforts. SPUR’s Ocean Beach staff works closely with many of these groups on sea level rise planning for Ocean Beach to facilitate communication and coordination while keeping the long view in focus.
Last month, Ocean Beach staff attended the 3rd Biennial Ocean Climate Summit, hosted by NOAA’s Gulf of the Farallones National Marine Sanctuary Program. The Summit gathers participants to collaboratively sustain the North-central coast and ocean ecosystem health. The conference garnered participation from 130 individuals across various fields to discuss the impacts of climate change and ocean acidification, as well as education and outreach efforts to inspire action within the community.
Science-based planning for resource managers
During the forum, we learned how to engage diverse audiences about climate change and ocean acidification, promote action, and advocate nature-based ‘climate smart’ conservation. One of the highlights was the beta launch of the Our Coast- Our Future Decision Support Tool, which models vulnerabilities from sea level rise and storm hazards for impactful decision-making. The science-based tool is useful for resource managers and local governments to anticipate coastal climate change impacts.
Getting the public involved
Another area of focus was framing complex topics like sea level rise and ocean acidification for non-scientific audiences. For instance, The California Academy of Sciences (CAS) has an entire program area dedicated to message framing for ocean acidification. It turns out, a simple example of linking the Ph level in lemonade to ocean acidification draws in CAS visitors effectively and also prompts them to think about solutions for healthy oceans. Learn about “Framed” Ocean Acidification Messaging.
A citizen supported project that utilizes the power of social media, the California King Tide Initiative encourages members of the public to upload photos of king tides, the highest seasonal tides on the California coast. The documentation is used to demonstrate how sea level rise impacts private property, public infrastructure, and wildlife habitat.
SPUR presents the Ocean Beach implementation studies!
The Summit is a great way to connect information, resources, and people across disciplines to work collaboratively, so we took the opportunity to share a poster on the Ocean Beach Master Plan implementation studies. These studies highlight SPUR’s proactive approach in planning for sea level rise and include a Transportation Analysis, a Coastal Management Framework, and Joint Open Space Planning.
This semester at the University of California at Berkeley’s Department of Landscape Architecture and Environmental Planning (LAEP), the Landscape Project Design studio (LA 203) examined Ocean Beach as their study site. Lead by Alma Du Solier, Principal at AECOM, fourteen Master of Landscape Architecture (MLA) students chose one of the six key moves of the Ocean Beach Master Plan (OBMP) and designed one small pedestrian node and a walkway that incorporated a strategy/element for passive energy harvesting to provide off-the-grid illumination. We would like to showcase these students’ work as examples of innovative ideas for addressing the complex issues facing Ocean Beach. However, **please note** these ideas do not represent the views of SPUR or OBMP stakeholders. Moving from south to north along Ocean Beach, each student provided a brief summary of their design concept, which precedes images of their work.
Steven Lee - Key Move 1+2
“The rerouting of the Great Highway at Sloat Boulevard makes it possible to re-imagine the southern end of Ocean Beach as a more socially and ecologically beneficial landscape. Based on the concept of shifted orientations, this project proposes a new public plaza and a pier that would extend half a mile into the ocean and overlook a dynamic sand island that would gradually erode away to counteract coastal erosion.”

Annie Hansel - Key Move 2
“My project is a reaction to the rapid erosion that is taking place in the south reach of Ocean Beach where the Lake Merced Tunnel and other sewer pipes are at risk of exposure in the near future. The infrastructure embedded in the portion of the coast in front of the Fleishhacker Building is strategically reinforced from above with steel sheet piles and concrete staples, allowing nature to run its course and gradually reveal the fixed landscape over time. The form of the site responds to current erosion trends and view sheds, and highlights the juxtaposition of the fluid landscape and the anchored infrastructure.”

Robin Kim - Key Move 2
“Using the Fleishhacker Pool House as the focal entry to the beach, my project combines infrastructure and eroding forces to reveal change through procession in space. New structures and pathways combined with the retrofitting of the pool house provide amenities for various users and allows flexibility in an ever-changing landscape.”

Katelyn Walker - Key Move 4
“Following Ocean Beach Master Plan key move four to "restore the dunes in the middle reach," this design looks at how people and infrastructure will be integrated into this new landscape without negatively impacting the ecology of the restored dunes. Primary paths to the beach, located at key intersections such as Judah Street, maintain their position in the new shifting native dunes through the use of sand fences, while secondary paths can be easily picked up and moved as the dunes change. A boardwalk promenade in the back dunes parallels the Great Highway and allows sand, plants, and animals to move underneath.”

Angela Delorenzo - Key Move 4+5
“My project looks into the boundaries between the urban area and the beach area represented by the seawall and the current man-made dune system. My analysis was based on understanding which are the key elements that persist to provide wilderness sense and recreational services.”
Image credit: Angela Delorenzo
Jenika Florence - Key Move 5
“This multidimensional gateway provides a new entryway experience to both Golden Gate Park and Ocean Beach at the intersection of the Great Highway and John F Kennedy Drive. Framing the Great Highway, new gathering spaces inspired by the park and the beach provide recreational amenities.”

Over the past two months, the National Park Service, Public Utilities Commission and Department of Public Works collaborated to move more than 73,300 cubic yards of sand from the north to the south end of Ocean Beach to provide protection against erosion. This process stabilizes the coast temporarily and provides useful data about coastal erosion rates. In addition to reducing the need for more engineered erosion protection measures, such as large piles of boulders, the Ocean Beach Sand Management Project also restores public access on the north end of the beach, where sand had built up, blocking the promenade and stairwells.
Why does sand erode in some places and accrete in others? Sand accumulates at the northern end of the beach through a complex interplay of natural sediment dynamics and management practices. Among other things, United States Army Corps of Engineers annually dredges the Golden Gate Marine Shipping Channel through an offshore sandbar and places the dredged sand in two sites, where it is picked up by ocean currents and eventually deposited on Ocean Beach. The effects are especially notable during the spring, when shifting winds and currents deposit significant amounts of sand and create large sand mounds in the north. This system is part of a pattern of sediment circulation that moves sand from the Golden Gate to about the middle of Ocean Beach, gradually pushing it northward. (See a video of this process in action.)
While the northern end of Ocean Beach has been widening due to these natural and manmade factors, the southern end of Ocean Beach experiences a net loss of sediment as circulation patterns move sand southward. Winter storms will probably cause additional erosion near Sloat Boulevard. Unchecked, this erosion is likely to have environmental consequences and damage city infrastructure, including San Francisco’s wastewater treatment system.
Going forward, the Army Corps of Engineers plans to eliminate the need to move sand by truck and will deposit dredged sand directly where erosion is worst. The Corps will move four times this year’s volume of sand from the Marine Shipping Channel and pump it directly onto the beach near the intersection of Great Highway and Sloat Boulevard. This beach nourishment project is fundamental to recommendations SPUR has made in the Ocean Beach Master Plan. It is also part of the Coastal Regional Sediment Management Plan, a new interagency effort between the Army Corps and the California Natural Resources Agency. That process will study sediment management options from Baker Beach in San Francisco to Shelter Cove in Pacifica, including beach nourishment, artificial reefs and managed retreat.
As SPUR and our partners continue to plan for climate change and sea level rise at Ocean Beach, these kinds of nimble, adaptive multi-agency efforts will become increasingly important. Projects like these help bridge the gap until SPUR’s Ocean Beach Master Plan recommendations can be implemented.
Some important improvements that SPUR recommended in the Ocean Beach Master Plan will happen right away, thanks to quick work by the San Francisco Department of Public Works (DPW) and the Recreation and Park Commission. This winter DPW will construct a planted median in the center of the Great Highway from Lincoln Way to Balboa Street as part of a previously scheduled project to repave the roadway. DPW acting director Mohammed Nuru, who sits on the Ocean Beach Master Plan Steering Committee, noticed that the long-range vision for Ocean Beach included street medians among its many suggested improvements. Rather than delay the repaving project while the long-term roadway proposals are analyzed, Nuru suggested that a median could be integrated into the current effort, provided it didn't change the configuration of the road, which would trigger a complex review process.
The project will install landscaped medians where today they exist only in paint. It will improve pedestrian safety and access to the beach by providing shorter crossings and pedestrian refuges, as well as clarifying rights of way on large swaths of currently unmarked pavement. It will also improve the aesthetics of the highway, as well as its environmental performance, by providing much-needed greenery and increasing permeable surfaces for stormwater infiltration in what is now a large, undifferentiated slab of asphalt. A selection of rugged native plants suitable for the beachfront’s challenging climate is under development.
The only concern that emerged about the project was ensuring that the Great Highway could continue to accommodate major events such as the Nike Marathon and Bay to Breakers races. A review of the proposal with Recreation and Parks Department event managers allayed those fears. The project went before the Recreation and Parks Commission Capital Committee in early June and the full Commission on June 21. Installation is set to begin as part of the larger repaving project this winter.
At last, the final Ocean Beach Master Plan document is ready for viewing and download! Many thanks to everyone who participated in this groundbreaking effort, including community members, advocates and public agencies. Check back here for updates on our implementation efforts.
