The Federal Emergency Management Agency (FEMA) is performing detailed coastal engineering analyses and mapping of the San Francisco Bay shoreline within the nine San Francisco Bay Area counties. The analysis and mapping will revise and update the flood and wave data for the Marin County Flood Insurance Study report and 49 Flood Insurance Rate Map panels along the San Francisco Bay shoreline.
On January 17, 2013, FEMA conducted a Flood Risk Review meeting in Marin County. At that meeting, FEMA shared the draft work maps with key stakeholders. FEMA solicited and received comments on the work maps from registered stakeholders using an online comment tool. Related project documents from this meeting are located in the menu below.
In October and November of 2013, FEMA shared the draft work maps and study information with communities at four public outreach meetings hosted by Marin County. The draft work maps and the slide presentation from these meetings are located in the menu below.
After careful consideration of all the comments received during the online comment period, the draft work maps were converted to Preliminary Flood Insurance Rate Maps (FIRMs). On March 24, 2014 the Preliminary Flood Insurance Study and the Preliminary Flood Insurance Rate Maps were mailed to the Marin County, City, and Town Chief Executive Officers (CEOs).
On April 10, 2014 a Community Consultation Officer meeting was held with community staff. FEMA has posted digital copies of the revised FIRM panels, FIS report, and Digital FIRM database to the following website: https://hazards.fema.gov/femaportal/prelimdownload/
FEMA representatives attended three community-hosted meetings the week of June 16, 2014.
The proposed Flood Hazard Determinations were published in the Federal Register on May 13, 2014. Following the publication in the Federal Register, the Flood Hazard Determinations were published twice in the legal ad section of the Marin Independent Journal on May 28 and June 4, 2014. The formal 90-day formal appeal period began on June 4, 2014 and ended on September 2, 2014.

, and amendments by way of FEMA Operating Guidance Procedure Memorandum 57, Expanded Appeals Process. Individuals and business owners who have questions or comments regarding the Preliminary Flood Insurance Rate Map should contact their local Floodplain Administrator.
FEMA anticipates mailing the Letter of Final Determination (LFD) and final Summary of Map Actions to the affect communities' Chief Executive Officer on September 16, 2015
. Approximately two weeks prior to the anticipated effective date (March 16, 2016), the communities will receive a revalidation letter from FEMA. This letter will confirm the Letters of Map Change (LOMC) determination that are still considered valid when the revised Flood Insurance Rate Map (FIRM) panels and Flood Insurance Study (FIS) report becomes effective.
Flooding is the most common disaster in the United States. Homeowners, renters and business owners are encouraged to look at the Preliminary Flood Insurance Rate Maps to become familiar with flood risks in their community. These flood maps can help individuals and businesses make informed decisions about flood insurance options and flood protection measures. Only Federal Flood Insurance reimburses homeowners for flood damage, most homeowners' insurance policies do not cover floods.

MarinMap has a web page and a GIS application specifically for FEMA flood information, including data a property owner could use when applying for a Letter of Map Change (LOMC). The new BAC Study Base Flood Elevation and Flood Hazard area zone polygons are in the GIS applications as follows: Select the page named “FEMA Flood Hazard Information” under the APPLICATIONS tab on MarinMap at: http://www.marinmap.org/dnn/Applications/FEMAFloodHazardInformation.aspx
Click on the link that directs people to one of two GIS applications (one for DeskTop and one for mobile devices). *Please note: Both Base Flood Elevation and Flood Hazard areas are in the public MarinMap Map Viewer application under the HAZARD folder. These are denoted with the suffix “Draft Bay Study” after the map name. Both Base Flood Elevation and Flood Hazard areas are in the members-only MarinMap Data Viewer application under the HAZARD folder (as in the public app).
