<div style='text-align:Left;'><p>This is an update of the digital
FIRM information in the state of Idaho.
This feature class shows areas depicting a Letter of Map Revision (LOMR)
boundary. The FIRM is the basis for
floodplain management, mitigation, and insurance activities for the National Flood
Insurance Program (NFIP). Insurance applications include enforcement of the mandatory
purchase requirement of the Flood Disaster Protection Act, which "... requires the
purchase of flood insurance by property owners who are being assisted by Federal programs or by
Federally supervised, regulated or insured agencies or institutions in the acquisition or
improvement of land facilities located or to be located in identified areas having special
flood hazards," Section 2 (b) (4) of the Flood Disaster Protection Act of 1973. In
addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on
the FIRMs are the basis for the establishment of premium rates for flood coverage
offered through the NFIP.</p>
<p style='margin-bottom:0in;'>This Database presents the flood
risk information depicted on the FIRM in a digital format suitable for use in
electronic mapping applications. This database has been created by digitizing
data from georeferenced paper FIRM maps in the Idaho counties specified by this
project. This data should be used as a
reference layer, not as an authoritative source.</p>
<p style='margin-bottom:0in;'> </p>
<p style='margin-bottom:0in;'>The Flood Insurance Rate Map
(FIRM) depicts flood risk information and supporting data used to develop the
risk data. The primary risk classifications used are the
1-percent-annual-chance flood event (A or AE) and the 0.2-percent-annual-
chance flood event (X). The FIRM data can be derived from Flood Insurance
Studies (FISs) and previously published Flood Insurance Rate Maps (FIRMs). The
FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).
This database has been created by digitizing data from georeferenced paper FIRM
maps and adding information from FIS where available. All FIRMs were
georeferenced at a 1:4000 scale or finer. This data should be used as a
reference layer, not as an authoritative source. </p>
<p style='margin-bottom:0in;'> </p>
<p style='margin-bottom:0in;'>Section 11 of FEMA's "Flood
Insurance Rate Map (FIRM) Database Technical Reference: Preparing Flood
Insurance Rate Map Databases (Nov. 2022)" document contains a detailed
description of each attribute code and a reference to other relevant information.</p>

<div style='text-align:Left;'><p><p>The hardcopy FIRM and the accompanying FISs are the official
designation of SFHAs and Base Flood Elevations (BFEs) for the NFIP. For the
purposes of the NFIP, changes to the flood risk information published by FEMA
may only be performed by FEMA and through the mechanisms established in the
NFIP regulations (44 CFR Parts 59-78). These digital data are produced in
conjunction with the hardcopy FIRMs and generally match the hardcopy map
exactly. However, the hardcopy flood maps and flood profiles are the
authoritative documents for the NFIP. Acknowledgement of FEMA would be
appreciated in products derived from these data.</p></p></div> |
