Notice of Availability and Finding of No Significant Impact - FM 2478


Purpose:

This notice advises the public that a final environmental assessment (EA) is available for public review and that TxDOT has issued a finding of no significant impact (FONSI) for the proposed Farm-to-Market Road (FM) 2478 widening from U.S. Highway (US) 380 to north of FM 1461 in Collin County, Texas.

Description:

The City of McKinney, in conjunction with TxDOT as the lead agency, are proposing to reconstruct and widen FM 2478 from US 380 to north of FM 1461 in Collin County, Texas, a distance of 3.174 miles. The proposed facility would consist of two 11-foot wide inside travel lanes and one 14-foot wide outside travel lane in each direction with two-foot wide inside and outside curb offsets, 22-foot wide outside borders, and a 16-foot wide raised median. The 22-foot wide outside borders would accommodate five-foot wide sidewalks. At various cross streets, the median would be reduced to accommodate a 10-foot wide left-turn lane, or 10-foot and 12-foot wide dual left-turn lanes and a 12-foot wide right-turn lane. A 22-foot wide connector road would be constructed approximately 1,600 feet south of where the realigned section of FM 2478 connects with existing FM 1461. The road would connect the realigned section of FM 2478 to the existing FM 2478. A 10-foot wide left-turn lane would allow northbound motorists on the realigned section of FM 2478 to access the connector road and existing FM 2478. The connector road would be constructed as part of the proposed project.

Construction of the proposed facility would be staged with the existing two-lane roadway first being expanded to four lanes. The proposed four-lane facility would consist of one 11-foot wide inside travel lane and one 14-foot wide outside travel lane in each direction with two-foot wide inside and outside curb offsets, 22-foot wide outside borders with five-foot sidewalks, and a 38-foot wide raised median. Expansion to the ultimate six-lane facility would occur at a later date. The proposed project would require approximately 36.8 acres of new right-of-way and 0.6 acre of permanent drainage easements.

To avoid noise impacts that may result from future development adjacent to a proposed highway project, a traffic noise analysis is included in the final EA, which includes predicted noise impact contours for currently undeveloped areas. These impact contours are intended as a general guide to assist local planning officials and developers plan and construct new activities in locations that would not result in traffic noise impacts. On the date of approval/clearance of an EA/FONSI (including the traffic noise analysis) for a proposed highway project, TxDOT is no longer responsible for providing noise abatement for new development.

The environmental review, consultation and other actions required by applicable federal environmental laws for this project are being, or have been carried-out by TxDOT pursuant to 23 U.S.C 327 and a Memorandum of Understanding dated December 16, 2014, and executed by the Federal Highway Administration and TxDOT.
