City of Hayward Regional Shoreline Master Plan
SB1 Adaptation Planning Grant: Initial Case Study
Challenge: Developing plans and strategies
The project began in October 2018 and will be completed by February 2021.
Lead Agency and Partnerships
Various entities maintain ownership and oversee the use of the Shoreline and its lands. A joint powers authority was created in 1970 between the City of Hayward, Hayward Area Recreation and Park District (HARD), and the East Bay Regional Park District (EBRPD). Known as the Hayward Area Shoreline Planning Agency (HASPA), the primary objective of the agency is to coordinate agency planning activities and adopt and carry out policies for the improvement of the Shoreline for future generations.
The Plan will support numerous State initiatives, including: implementing a SLR Adaptation Plan (E.O. S-13-08), prioritizing natural infrastructure within the Plan (E.O. B-30-15), aligning with the California Transportation Plan 2040, and various local and regional initiatives.
Historically, HASPA primarily focused on preserving shoreline land for recreation; however, over time HASPA has realized that the Shoreline serves as the first line of defense against the impacts of SLR. The areas adjacent to the Shoreline include Hayward’s Industrial Technology and Innovation Corridor and various residential neighborhoods. In addition, the Shoreline is home to the eastern approach of SR 92, which is used by over 90,000 individuals daily. Without combating the anticipated impacts of SLR, these areas will be inundated and cause hundreds of millions of dollars of damage. In addition, the project will address disadvantaged communities who use the shoreline. The San Francisco Bay Conservation and Development Commission (BCDC) Adapting to Rising Tides Program created an indicator list for disadvantaged communities at risk for flooding (language, vehicle access, housing cost, race/ethnicity, education, housing tenure, transportation cost, elderly and youth population, and income), and nearly all residential communities near the Shoreline exemplified multiple indicators. To address the concerns of stakeholders, the Plan includes a Community Outreach Plan (COP) that includes strategies such as surveys and interviews to obtain input.
Climate Impact Area
The project will address the future and current effects of SLR. Presently, aging levees are overtopping, causing parts of the Shoreline, including the Bay Trail, to flood two to three times a year. Furthermore, flooding could result in the loss of natural habitat, as well as major damage to adjacent industrial areas, essential facilities, and infrastructure related to transportation corridors, utilities, and waste processing. According to these impacts will become worse without mitigation efforts. The Plan will outline various strategies to counteract the effects of SLR, and include specific short-, medium-, and long-term projects that will benefit the Shoreline and surrounding communities. Given the varying uses of the Shoreline, the Plan will utilize projects and tools, which will provide multiple benefits. The use of natural infrastructure and co-beneficial projects will be a priority for the Plan.
The project is being funded by a $509,000 Caltrans Adaptation Planning Grant, and a local cash match of $175,000. The total funding for the project is $684,000.
Research and Data
Many different resources were used to gather preliminary data regarding the Plan. Some of these resources include: Adapting to Rising Tides (ART), Safeguarding California, Adaptation Planning Guide, UC Davis Governance Gap: Climate Adaptation and Sea-Level Rise in the Bay Area, Rising Seas in California, Climate Change and Extreme Weather Options, and many more. In addition, two Hayward specific studies were utilized: Preliminary Study of the Effects of Sea Level Rise on the Resources of the Hayward Shoreline and the Hayward Resilience Study, which is an extension of the Adapting to Rising Tides Project.
There are no anticipated challenges with the completion of the Plan; however, time will tell regarding the feasibility of projects outlined.
The Plan will outline an overall strategy and specific projects to combat the effects of SLR. The overall strategy will provide a regional approach, which will allow HASPA and the Shoreline to effectively and efficiently prepare for and adapt to SLR. Specific projects will be identified to allow HASPA to pursue implementation in the following years.
The Shoreline mimics the conditions of many communities surrounding the San Francisco Bay; therefore, replication is feasible. SLR will affect coastal communities everywhere, and climate adaptation planning efforts will become the norm throughout the nation and especially the San Francisco Bay. Appropriate preparation and research are necessary to facilitate effective measures to minimize the effects of SLR. Different cities and agencies could utilize the research conducted as part of the Plan to better understand the impacts of SLR. Furthermore, these cities and agencies could also utilize some of the proposed adaptation strategies and adjust these strategies to address their specific desires, needs, and situation.
