COUNTYor SAN MATED DEPARTMENT OF PUBLIC WORKS FLOOD RESILIENCE PROGRAM Exhibit A Public Outreach and Education: A public outreach and education plan will be developed as part of the Project. This outreach plan will be used to inform and educate the public and other stakeholders on the specifics of existing flood risks, potential solutions, and necessary green/grey infrastructure and operation and maintenance investments needed to alleviate flooding in the area. Consistent messaging and informational materials will be shared with the Collaborative to publish on their respective websites and for public distribution. The goal of this effort is to ensure that the impacted communities and stakeholders have a clear understanding of the flood risk reduction this Project will'provide, and to educate them on other'proiects in the system that will need to be completed to ensure the region remains resilient to flooding to the extent possible. Future Work: The Project is limited to the planning, design, environmental permitting, and easement negotiations necessary to advertise for bidding. Land rights resulting from legal transfer and holding of easements will belong to the jurisdiction in which the land exists. Negotiations of any necessary easements or land acquisitions will be facilitated with support from the County, the Collaborative, and the design Consultant. Future Addendums, MOLIs, or Agreements will be required to address the construction and maintenance of the Project. In addition to this Project, potential flood mitigation provided by upstream stormwater retention projects in the Bayfront Canal and Atherton Channel watersheds will be analyzed by the Collaborative as needed. Flow allocations per jurisdiction may be adjusted if it appears that upstream detention improvements reduce flow contributions to the Project and once the improvements have obtained significant design and funding. Table 2 below describes the potential future projects that may affect the existing flow contribution allocations listed in Table 1. Table 2.
