a - COUNTYoF SAN MATEO o DEPARTMENT OF PUBLIC WORKS u FLOOD RESILIENCE PROGRAM Exhibit A 6.1.A. - Page 19 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 projects 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. The deeds will be held by each jurisdiction. Negotiations of any necessary easements or land acquisitions will be facilitated with support from the County, the Collaborative, and the design Consultant. Future Addendums, MOUs, 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 need to be adjusted if it appears that upstream detention improvements reduce flow contributions to the Project. Table 2 below describes the potential future projects that may affect the existing flow contribution allocations listed in Table 1. Table 2.
