Freeport Il LOMR Along Cottonwood Branch at Denton Coppell, TX Langan Project No. 520085501 Dear Property Owner: The Flood Insurance Rate Map (FIRM) for a community depicts the Special Flood Hazard Area (SFHA), the area that has been determined to be subject to a 1-percent or greater chance of flooding in any given year. The regulatory floodway is the portion of the floodplain that includes the channel of a river or other watercourse and the adjacent land area that must be reserved in order to discharge the 1-percent-annual- chance (base) flood without cumulatively increasing the water-surface elevation by more than a designated height. The FIRM is used to help the community with floodplain management. Langan is applying for a Letter of Map Revision (LOMR) from the Federal Emergency Management Agency (FEMA) on behalf of Alliance Industrial, LLC to revise FIRM 48113C0135K for City of Coppell along Cottonwood Branch at Denton. Alliance Industrial, LLC is proposing to revise the FIRM to reflect improvements for one warehouse. The City of Coppell, in accordance with National Flood Insurance Program regulation at 44 CFR §65.7(b)(1), hereby gives notice of the City’s intent to revise the 1-percent-annual-chance floodway, generally located downstream of Freeport Parkway. Specifically, the floodway shall be 1. Revised from a point from 1600 feet downstream of Freeport Parkway to 40 feet downstream of Freeport Parkway Asa result of the LOMR, the regulatory floodway will narrow within the area of revision. The LOMR will result in: 1. Increases and decreases in the 1-percent-annual-chance water surface elevations. 2. Widening and narrowing of the 1-percent-annual-chance floodplain. This letter is to notify you of flood hazard revisions on your property. Maps and detailed analysis of the flood hazard revisions can be reviewed at the City of Coppell Engineering Department located at 265 E Parkway Boulevard Coppell, TX 75019.
