Getting Started Using Our Coast, Our Future (OCOF)

Thank you for using the Our Coast, Our Future website. The following steps will help you get started using the modeling results for sea level rise and storms.

Get familiar with the project.

If you are brand new to OCOF, we suggest you look over these resources to get a quick introduction to the project and how OCOF can benefit your work.


If you are unfamiliar with OCOF, this two-page introduction will provide an overview of the project and the tools available on this website.

How OCOF can help you.

Read about who this project was developed for, what types of planning and outreach can benefit from this information, and where OCOF fits in the climate change adaptation planning process.

Learn how to use the online tools.

OCOF will eventually provide sea level rise and storm scenarios for the entire coast of California and the San Francisco Bay. Currently the tool includes outputs for the north-central California coast (from approximately Half Moon Bay north to Point Arena) and the San Francisco Bay. Southern California (from Point Conception south to the Mexican border) will be coming online in Winter 2016. These resources will help you navigate the online tools we have available to explore these results.


Take a few minutes and watch the Project Overview and Flood Map tutorials. These two short videos will introduce you to the project, and describe how to use the tools available on this website.

Frequently Asked Questions about OCOF

We have provided answers to frequently asked questions about the OCOF project including general information, geographic coverage, data used, model development, and the flood mapping tool.

Understand more about the Coastal Storm Modeling System (CoSMoS)

CoSMoS, developed by the U.S. Geological Survey (USGS), is the modeling approach used to estimate sea level rise and storm scenarios. We feel CoSMoS provides some of the most accurate and detailed results available for California.

Frequently Asked Questions about CoSMoS

We have provided answers to frequently asked questions about the USGS Coastal Storm Modeling System (CoSMoS) used to develop the sea level rise and storm scenarios.

Scientific Literature

For a deeper dive into the scientific basis for CoSMoS, we have provided key citations supporting the research behind this approach to modeling sea level rise and storms.

Known issues in your area.

Read about any specific issues that arose when projecting flood vulnerabilities in a given region or by scenario.

Discover how other partners use OCOF.

The Case Studies page lists other organizations who are using OCOF and the CoSMoS models for understanding the effects of sea level rise and storms in their areas and communicating those impacts to their audiences. As you begin to use these models for your projects, please let us know what you are doing so we can add you to our ever growing list of OCOF users and let other new users learn from you.

Explore our scenarios.

Go to the Flood Map and see what OCOF has to say about flood extent under different scenarios for your areas of interest. Look for the Get Started button at the top left corner of the Flood Map screen to get additional help using the map.
