The Hayward Area Shoreline Planning Agency (HASPA) prepared the Shoreline Adaptation Master Plan to determine the policies and projects necessary to prepare for sea level rise along the Hayward Shoreline. The shoreline is home to critical infrastructure such as the City’s wastewater treatment plant, the eastern approach to the Hayward-San Mateo Bridge (State Route 92), and flood protection. The area also has many natural features such as marshlands and shoreline, along with residential neighborhoods, business parks, and recreational features such as the Bay Trail and the Hayward Shoreline Interpretive Center.

This grant-funded project provided a suite of mitigation actions and policy recommendations to improve the City’s capacity to plan for, prepare for, mitigate against and adapt to sea level rise. The project's focus was on protecting the City’s most important natural and community assets. HASPA is a joint powers authority consisting of the City, the Hayward Area Park and Recreation District (HARD), and the East Bay Regional Park District, was established in 1970 whose purpose is to coordinate agency planning activities and adopt and implement policies for the improvement of the Hayward Regional Shoreline for future generations.

Previous Studies

In 2010, HASPA completed a Preliminary Study of the Effect of Sea Level Rise on the Resources of the Hayward Shoreline. In 2011 through 2013, HASPA partnered with the Bay Conservation and Development Commission’s Adapting to Rising Tides (ART) Program to conduct a Resilience Study which further assesses vulnerabilities and identifies potential adaptation strategies.
