Notes

Scope and Content:
This document provides guidance for incorporating sea‐level rise (SLR) projections into planning and decision making for projects in California. Governor’s Executive Order S‐13‐08, which was issued on November 14, 2008, included the following: I direct that, prior to release of the final Sea Level Rise Assessment Report from the NAS [National Academy of Sciences], all state agencies within my administration that are planning construction projects in areas vulnerable to future sea level rise shall, for the purposes of planning, consider a range of sea level rise scenarios for the years 2050 and 2100 in order to assess project vulnerability and, to the extent feasible, reduce expected risks and increase resiliency to sea level rise. However, all projects that have filed a Notice of Preparation, and/or are programmed for construction funding the next five years, or are routine maintenance projects as of the date of this Order may, but are not required to, account for these planning guidelines. Sea level rise estimates should also be used in conjunction with appropriate local information regarding local uplift and subsidence, coastal erosion rates, predicted higher high water levels, storm surge and storm wave data. The final report from the National Academy of Sciences (NAS) is unlikely to be released until 2012. The intent of this interim guidance document is to inform and assist state agencies as they develop approaches for incorporating SLR into planning decisions prior to the release of the NAS report and other technical reports (see below for information on planned updates to this document). Specifically, it provides information and recommendations that will enhance consistency across agencies in their development of approaches to SLR. We anticipate that, because of their differing mandates and decision‐making processes, state agencies will interpret and use this document in a flexible manner, taking into consideration risk tolerances, timeframes, economic considerations, adaptive capacities, legal requirements and other relevant factors. (Refer to Recommendation #2 below for a discussion of risk tolerance and adaptive capacity.) Although the estimates of future SLR provided in this document are intended to enhance consistency across California state agencies, the document is not intended to prescribe that all state agencies use specific or identical estimates of SLR as part of their assessments or decisions.
