FEMA FAQs and messages

Below you will find a listing of commonly asked questions and their answers. If you don't find your question listed, Marin County can provide one-on-one flood information at the Permit Counter located in the Marin County Civic Center, Room 308.  There are Land Development Engineers available to answer questions about flood maps, flood zones, base flood elevations (BFE), elevation certificates and to determine whether your property is located in a Special Flood hazard Area (SFHA).

FAQs

If your home is in a Special Flood Hazard Area (SFHA) you must build your home so that the finished flood elevation is at least one (1) foot above the FEMA Base Flood Elevation (BFE). FEMA updates their maps and BFE regularly so it can be assumed that the BFE for your structure will change over time. It may be prudent to build, remodel, or elevate your home more than one foot above the BFE to protect yourself, your family, and your possessions.

It depends on the reason for the change in the flood zone. If a property owner thinks their property has been inadvertently mapped in a Special Flood Hazard Area or is now out of the flood zone due to elevating the structure or another reason, they may submit a request to FEMA for a Letter of Map Change  or Amendment (LOMA). The requirements of the LOMA depend upon the reason for the requested change in flood zone and may require the applicant to hire a licensed surveyor or engineer. For more details, visit https://www.fema.gov/flood-maps.

The Special Flood Hazard Area (SFHA) is defined by FEMA as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year (sometimes called the “100-year” flood). Flood-hazard maps or flood insurance rate maps (FIRMs) have been created by FEMA to show the flooding risk for your community, which help determine the cost of flood insurance. The lower the degree of risk, the lower the flood insurance premium. Properties in the SFHA may be subject to the mandatory flood insurance purchase requirements of the National Flood Insurance Program (NFIP). A good source of flood information is the Homeowner FAQs. You can also contact the Land Development Division of the Department of Public Works for FEMA flood zone information. They can be reached by phone at 415-473-3755, by email, or in person in Room 308 at the Marin County Civic Center.

Elevation Certificates can only be completed by a licensed land surveyor, engineer, or architect who is licensed by the State to perform such functions. Copies of completed elevation certificates that have been submitted to the County are available at the Land Development office in Room 308 at the Marin County Civic Center.

Standard homeowners insurance doesn’t cover flooding. It is important to have protection from the floods associated with hurricanes, tropical storms, heavy rains and other conditions that impact the U.S. Find out more about the NFIP and how it can help you protect yourself by visiting Floodsmart.gov.

Anywhere it rains, it can flood. A flood is a general and temporary condition where two or more acres of normally dry land or two or more properties are inundated by water or mudflow. Many conditions can result in a flood: hurricanes , overtopped levees, outdated or clogged drainage systems and rapid accumulation of rainfall.

Just because you haven’t experienced a flood in the past, doesn’t mean you won’t in the future. Flood risk isn’t just based on history, it’s also based on a number of factors: rainfall, river-flow and tidal-surge data, topography, flood-control measures, and changes due to building and development.

Floods are one of the most common hazards in the United States. Flooding can be local, impacting a neighborhood or community, or larger, affecting entire river basins and multiple states. However, all floods are not alike. Some floods develop slowly, sometimes over a period of days and weeks. But other kinds of flooding known as flash floods can develop quickly, sometimes in just a few minutes and without any visible signs of rain. Flash floods often have a dangerous wall of roaring water that carries rocks, mud, and other debris and can sweep away most things in its path. Overland flooding occurs outside a defined river or stream, such as when a levee is breached, but still can be destructive. Flooding can also occur when a dam breaks, producing effects similar to flash floods. Just a few inches of water from a flood can cause tens of thousands of dollars in damage. Each year, more deaths occur due to flooding than from any other severe weather related hazard.

Be aware of flood hazards no matter where you live, but especially if you live in a low-lying area, near water or downstream from a dam. Even very small streams, gullies, creeks, culverts, dry streambeds, or low-lying area that may appear harmless in dry weather can flood. Every state is at risk from this hazard.
