Sea Level Rise Guidance

The following instructions were created to establish and apply a consistent and comprehensive review, planning, and implementation process to carry out the “Guidance for Incorporating Sea Level Rise (SLR) into Capital Planning in San Francisco.”

The guidance was originally adopted by the Capital Planning Committee on September 22, 2014; revisions and a supplement were adopted on December 14, 2015. Materials referred to in this Step-by-Step Guide are provided on this page.

Please contact Hemiar Alburati to request a Geodatabase (GIS file) of the SLR Vulnerability Zone Map (overlaid on San Francisco base layers).

Short-Term Submission Requirements

1. Each department with responsibility for implementing capital projects should do the following:

  1. The SFPUC and its Sewer System Improvement Program consulting firm, AECOM, will provide information and training as requested to each department to assist in implementing the SLR Guidance, use of the SFPUC inundation maps referred to in the Guidance and Checklist, and completion of the Checklist.
  2. All submissions and any accompanying vulnerability assessment materials will be forwarded to the Public Works Department – City Engineer’s Office by February 10.
  3. The City Engineer will utilize existing resources available within DPW to combine all CCSF mapped projects provided by departments on a GIS map. The City Engineer’s Office will interact directly with each department as needed to clarify meaning or correct any deficiencies. This interaction could include any needed hydraulic, structural, regulatory, or other reviews to verify vulnerability assessments should the Capital Planning Committee or the department responsible for the asset deems it necessary.
  4. At the request of the Capital Planning Committee Chair, the City Engineer will prepare and submit a report on projects submitted for the Capital Plan.
  5. Submissions for capital projects seeking funding through the budget process will be due by March 15. Projects seeking funding for a supplemental appropriation will be due two weeks prior to the date at which the supplemental will go before the Capital Planning Committee.

Long-Term Requirements

  1. Departments that have projects within the Vulnerability Zone will need to provide specific long-term strategies to specifically address sensitivity and adaptive capacity as defined in the Sea Level Rise Guidance. This will occur at the time for bond proposals or other funding requests.
  2. The City Engineer’s Office (Public Works), in collaboration with the City's SLR Coordinating Committee if needed, will assist client departments in developing specific long-term strategies to specifically address sensitivity and adaptive capacity of individual projects.

Please contact David Behar for further information.

  1. Identify and map project sites included in the ten-year Capital Plan or submitted within a budget or supplemental request to verify if it falls within the area defined as the SLR Vulnerability Zone. “Vulnerability Zone” is defined and mapped by the SLR Coordinating Committee as the area that would be impacted by SLR in the Year 2100 by a combination of unlikely but possible high end SLR plus a 100-year flood. The Vulnerability Zone map will be provided to departments as a shape file in ArcGIS for inputting at their request.
  2. Fill out the Sea Level Rise Checklist for each of the capital projects over $5 million that have been identified for funding over the next ten years. Please note that in order to complete the Checklist correctly, Departments must review the full Guidance.
  3. Submit the completed forms to the Capital Planning Committee by January 31. Departments are encouraged to submit their completed Checklists earlier than the deadline to allow for timely review by CPC and City Engineer.
  4. In cases where projects are at an early stage of development or within a program that doesn’t have specific information but are or may be within the Vulnerability Zone, inform the CPC staff and the City Engineer when specific projects will be defined and the checklist will be completed.
