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.

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.”

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.
