Broglan Branch Flood Study

FEMA Conditional Letter of Map Revision (CLOMR)

Application Request Data and Related Information

for Broglan Branch 

Updated 02/14/2011

Property Owners/Tenants,

 The City of Huntsville has prepared revised Floodplain and Floodway boundaries, based on updated hydrologic and hydraulic modeling, along Broglan Branch from just east of the Nelson Dr. and Brookline Dr. “T” intersection downstream (south) to its confluence with Huntsville Spring Branch south of Governors Dr. Additionally, the City is including some proposed bridge improvements for the Clinton Ave. crossing over Broglan Branch. A draft Conditional (i.e. it’s conditional on the proposed bridge improvement being appropriately completed) Letter of Map Revision (CLOMR) application package has been prepared to submit to the Federal Emergency Management Agency (FEMA) to request legal revision of their existing/Effective Flood Insurance Rate Maps (FIRM) to reflect the updated modeling.

The information in the CLOMR application package as been incorporated into the Federal Emergency Management Agency (FEMA) National Flood Insurance Program (NFIP) Madison County wide Map Update.  Please visit the following link for further information and options for viewing the "Preliminary" mapping:  http://huntsvilleal.gov/flood. 

Some areas may see an improvement to the conditions currently shown on the Effective FIRM, whereas others are adversely impacted, based on the updated and more accurate data used to depict the proposed conditions.  In areas where Base Flood Elevations (BFEs) have been lowered, the decrease may be enough to reflect a decrease in Flood Insurance rates subsequent to FEMA’s review and publication of a LOMR (although new Elevation Certificates will likely have to be done, at the owner’s/insured’s cost, to demonstrate the change to insurance companies/FEMA).
