Runway 34 Medium Intensity Approach Light System with Runway Alignment Indicator Lights (MALSR)

Federal Aviation Agency (FAA) on behalf of the City of Arlington, Texas

Arlington Municipal Airport, Arlington, Texas

CATEX Review, Environmental Assessment, 404 Permitting and Archaeological Survey

An image of a satellite map with a multi-layer overlayThe initial project scoping for the Arlington Airport MALSR Lighting Project indicated that the project merited a CATEX because the project was required to meet Federal mandates associated with the Homeland Security Act. However, the initial dse review of the CATEX, (as prepared by others) indicated that the CATEX did not address jurisdictional wetlands, floodplain construction requiring a Section 404 permit, Section 4(f) park impacts associated with a city trail, and cultural resources. Thus the project merited an EA. (In addition, the Homeland Security Act is not formally included on the list of allowable exclusions related to the CATEX process). dse developed the Draft EA on an expedited timeframe, and completing the formal community input and public information process, including contacting over 200 individual landowners that are located within one-half mile of the proposed airport lighting improvements. dse also subcontracted and oversaw the completion of an Archaeological Survey.
