Special Flood Hazard Area  Removal

A structure, property or a portion of a property can be removed from a special flood hazard area by submitting to FEMA a qualifying letter of map change request.

There are numerous types of requests for various types of situations. Not all properties can qualify for a letter of map change. Some can qualify by placing fill at the property, but this may not always be feasible or permissible.

For most letter of map amendment (LOMA) requests, Alaco utilizes FEMA's eLOMA platform for licensed professionals to expedite processing. LOMA requests are typically processed by FEMA representative Michael Baker/North Wind.

Building in a Special Flood Hazard Area

Local ordinances typically require those building within a special flood hazard area to provide three completed FEMA elevation certificates throughout the various building stages in order to validate a permit. The first documents pre-construction conditions. The next is done at the stage of foundation forming/lowest floor framing to ensure minimum required elevations will be met. The final certificate is to document code/permit conformance upon completion of construction. 

Sometimes, and always when the special flood hazard area is also designated a regulatory floodway, a "no-rise" certification indicating that there will be no rise in the base flood elevation will be required.

Preferred Risk Rate for Flood Insurance

An elevation certificate is an official FEMA form for recording ground and building elevation measurements. The forms are used to comply with local building ordinances and to determine flood insurance rates for policies issued through the National Flood Insurance Program (NFIP). An elevation certificate can also be used to support an LOMC request. Project owners can pursue map changes through FEMA's Online LOMC site.

In most cases the forms must be prepared and certified by a professional engineer or land surveyor. However, depending on insurance company requirements, certification might not be necessary for the purpose of rating an NFIP policy in a Zone AO. 

Special Flood Hazard Area

What is a special flood hazard area?  It is an area that has a one percent chance of being flooded in any given year as determined by the Federal Emergency Management Agency (FEMA). Thought of another way, it is an area that is expected to flood at least once every one hundred years. Hence, it's sometimes referred to as the 100-year floodplain.

FEMA identifies special flood hazard areas by way of flood insurance studies usually prepared by study contractors like AECOM or cooperating technical partners like the Alameda County Flood Control District.  The results are delineated on flood insurance rate maps. 

These studies and maps can be viewed and downloaded at FEMA's online Map Service Center


Base Flood Elevation and Lowest Adjacent Grade

The elevation of flooding that determines if a structure is in or out of a special flood hazard area or otherwise establishes the rate of flood insurance is the base flood elevation (BFE). It is derived from FEMA's flood insurance studies and flood insurance rate maps. 

A structure shown to be in a special flood hazard area on a flood insurance rate map can potentially be removed if it can be demonstrated that the lowest adjacent grade to the structure is at or above the BFE. 


Floodway - a special type of Special Flood Hazard Area

A special flood hazard area that is also designated as a regulatory floodway, as indicated by stripes on a flood insurance rate map, has special requirements for LOMC requests and new development. 

Pictured below is the northeast corner of Castro Valley Boulevard and Lake Chabot Road in Castro Valley. Back when the mall was being developed, the location was included as part of a regulatory floodway. Consequently, the building needed to be elevated on piers, above the base flood elevation, so as not to impede the flow of flood water.  (The floodway designation no longer applies to the property.)

Special flood hazard areas are classified and shown as zone types. Each zone has a separate set of rules for determining a base flood elevation. This value can then be used to establish:

There are over 16,000 impacted parcels in Alameda County. The accompanying table shows the number of parcels included in each zone type. Some parcels are included in more than one zone.

Flood Insurance Mandate

The Federal Flood Disaster Protection Act of 1973 mandates that federally regulated lenders cannot make, increase, extend, or renew a loan for a structure unless it is insured against flood damage when any portion of it is located in a special flood hazard area. This Federal requirement for insurance applies to federally regulated lenders, not directly to property owners. A regulated lender simply passes this obligation onto its client. Consequently, an owner of a structure in a special flood hazard area who does not have a federally regulated loan is not required to have flood insurance.

Those who do not presently have a federally regulated loan may still want to  seek a LOMC as a future desire or need for a home equity loan will likely require flood insurance. Also, a home in a special flood hazard area might be considered overpriced and, therefore, may be more difficult to sell. 

Lender's Determination of Insurance Requirement

A data analytic company, such as CoreLogic, reviews flood insurance rate maps and then makes the determination for its lender clients as to whether a structure is shown in or out of a special flood hazard area.  Some companies will interpret the maps more conservatively by extending the flood boundary by an extra 25-feet or so.

It is a lender's prerogative, per the mortgage agreement or deed of trust, to require flood insurance whether the property owner agrees with the determination or not.

Of course, if a structure for which a lender demands flood insurance is shown far outside of a special flood hazard area, an owner's recourse is to refinance with another lender who interprets the map more favorably.  Alternatively, an Out-As-Shown LOMA can be sought directly from FEMA. It is unusual for a lender to require flood insurance when FEMA has issued a LOMA for the structure.


Alaco's Fees for Flood Hazard Services

Alaco attempts to provide its clients with only the services they truly need, for attaining the most favorable result, at the least possible cost. Hence, services are itemized as described below. To better understand how these fees are applied, view the details associated with the flood zone impacting the property: Zone A, Zone AE, Zone AH, or Zone AO. In some rare instances multiple zones impact a property and the criteria described for both zones applies. 


The fees listed above are valid through Dec 31, 2022 and may increase thereafter. 

Obtaining Insurance

Flood insurance can be purchased either through FEMA's National Flood Insurance Program or the private market. The vast majority of flood insurance policies are issued through the NFIP.  However, private market policies are becoming more popular as companies identify areas where the risk determined by FEMA may be overestimated. In these areas the private market is undercutting the NFIP. 

If you are informed by you lender that you must obtain flood insurance, begin investigating your options right away. If you do not obtain flood insurance in a timely manner, your lender will do so on your behalf. In doing so, the lender will not choose the most economical approach for you, but you will be obligated to pay the expense. Lenders often obtain month-to-month private policies without any surveyor obtained data, rather than annual policies that normally have a lower monthly cost. If you obtain insurance through the NFIP and then later prove it was not required by acquiring a LOMA, you will be eligible to receive a full refund for your effective policy, as long as you did not file a claim during the policy period.

National Flood Insurance Program

NFIP policies are offered and serviced by the agencies of most major insurance companies, such as AAA, Allstate, Farmers, Liberty Mutual, Nationwide, Progressive, State Farm, The Hartford (AARP), Travelers, USAA, etcetera. Be aware, however, that not every agent affiliated with a particular company will offer NFIP insurance. So if you prefer to maintain various insurance policies under one company, it may be necessary to seek a different agent. Also, not every company offers NFIP insurance unconditionally. Some will only write policies for existing clients in good standing.

No matter which agent/company offers to provide NFIP insurance for a property, the cost should be the same for the same policy coverage. NFIP policy prices are fixed by FEMA. Consequently, there shouldn't be any benefit to shopping around for NFIP quotes, except that it is not uncommon for insurance raters to err in determining policy costeither in favor of or to the detriment of their clients.  Legitimate costs savings may be possible through insurers who provide overall discounts for bundling multiple policies. 


NFIP Insurance Cost

The cost of an NFIP flood insurance policy is guided by FEMA's Flood Insurance Manual using data recorded on a current Elevation Certificate form.

Discounts are available to properties that are located in communities that participate in FEMA's Community Rating System (CRS). Communities in Alameda County that participate in the CRS program include:

. . . all other communities

Private Flood Insurance

A potentially less expensive alternative to FEMA's NFIP insurance is flood insurance offered by the private sector. But before allowing any existing NFIP policy to lapse, ensure that any private insurance you do consider is acceptable to your lender.

Also, consider that any grandfathered NFIP discount currently applied to your property might be lost forever by not continuously maintaining an NFIP policy. There is no guarantee that a privately offered policy will be available for renewal in the future, especially after filing a claim.
