AB 691 - Proactively Planning for Sea-Level Rise Impacts
Criteria and Resources
- Assembly Bill 691 (Muratsuchi), Chapter 592, Statutes of 2013
- Assessment Criteria
- Informational Webinars and Powerpoint Presentations
This AB 691 informational webinar was produced from the collaborative efforts of the Commission with the State Controller's Office, California Coastal Commission, State Coastal Conservancy, Ocean Protection Council, and the San Francisco Bay Conservation and Development Commission. It aims to help grantees better understand what resources are available and the process for submitting a robust sea-level rise assessment.
The purpose of this second informational webinar is to assist grantees with estimating the financial costs of sea-level rise impacts to public trust resources. The Commission hosted Maya Kocian, Program Director for Ecosystems Services Valuation and Senior Economist at Earth Economics, who delivered a presentation on ecosystem services and the various methodologies for assessing natural capitol.

Estimating financial costs of sea-level rise
Considering the financial costs associated with the impacts of sea-level rise will facilitate successful adaptation planning and the protection of Public Trust lands and resources. When estimating costs, replacement or repair of existing facilities may be a factor, as well as the quantification of non-market asset values such as recreation and ecosystem services. Costs may be projected across the same time scales as sea-level rise (e.g., 2030, 2050, and 2100). In addition to a tally of losses, the cost of adaptation and mitigation strategies should be estimated, along with the potential economic benefits of those strategies. The following resources and tools are available to assist you:
- Duke University Marine Ecosystem Services Partnership
- Economic Impacts of Climate Adaptation Strategies for Southern Monterey Bay
- MIIS National Ocean Economics Program
- What Will Adaptation Cost? An Economic Framework for Coastal Community Infrastructure
Protecting Public Trust resources impacted by sea-level rise
As Public Land Trustees, granted lands partners ensure the protection of Public Trust resources and values. Please describe in your assessment how proposed sea-level rise adaptation and mitigation strategies will address the coastal asset vulnerabilities identified and the time frame for implementation of such measures. Include any plans to monitor the impacts of sea-level rise and the effectiveness of implemented adaptation and mitigation strategies.
Assessing Sea-Level Rise Impacts
To assess sea-level rise impacts to granted lands, first inventory vulnerable natural and built resources and facilities. Then, consider the impacts of sea-level rise itself and other dynamic coastal processes and climatic events that are projected to be exacerbated by sea-level rise such as coastal erosion, storms, and high tides on the vulnerable assets identified. The following resources and tools are available for assistance:
There are many free, public, online sea-level rise viewing tools that can be used to create maps of sea-level rise conditions for 2030, 2050, and 2100. FEMA flood hazard maps will also be accepted, if projected time frames match the above years or are appropriately similar. The following resources and tools are available for assistance:
