Release no. 12-003


FORT WORTH, Texas – The Fort Worth District, U.S. Army Corps of Engineers is currently accepting comments on the Environmental Assessment, a National Environmental Policy Act document, for the modifications to the East and West Levees of the Dallas Floodway System in the City of Dallas.

The City of Dallas proposes implementation of cutoff walls to address potential for underseepage and help regain 100-year FEMA accreditation. The Proposed Action would not have any significant impacts on the social, economic, or human and natural environment. No effect on any species that are proposed to be or are listed as threatened or endangered under the Endangered Species Act is expected. No significant transportation, land use, or environmental justice concerns were identified within the project area. The long-term effects of the Proposed Action would be beneficial as it would help regain 100-year FEMA accreditation.

Proposed construction measures and operation and maintenance features of the project will meet the criteria for Regional General Permit 12 - "Modification and Alterations of Corps of Engineers Projects." It was determined that appropriate mitigation for permanent impacts to waters of the U.S., including wetlands, would be to construct a 0.5 acre wetland within the project area. The mitigation site would be contoured using multiple elevation gradients to a maximum depth of three feet to allow for vegetation with appropriate wetland herbaceous species.

Copies of the EA and Draft Finding of No Significant Impact are available for review at the Dallas Central Public Library (1515 Young Street, Dallas, TX 75201) and at the Dallas West Branch Library (2332 Singleton Blvd., Dallas, TX 75212) or by visiting the project website at www.swf.usace.army.mil/pubdata/notices/DallasFloodway/. Copies may be requested in writing from Marcia Hackett, CESWF-PER-EE, P.O. Box 1733, Fort Worth, TX 76102-0300, by telephone at (817) 886-1373. Written comments on the EA will be accepted through Dec. 20 by sending them directly to the above address or by e-mail at marcia.r.hackett@usace.army.mil.
