Notice of Availability - Finding of No Significant Impact - SL 335 Segment B-2


This notice advises the public that a final environmental assessment (EA) is available for public review and TxDOT has issued a finding of no significant impact (FONSI) for proposed improvements to SL 335 from FM 2590 to SW 9th Avenue in Randall and Potter counties.


The proposed SL 335 Segment B-2 project consists of upgrading existing roadways and a new location alignment to a controlled access facility including bicycle and pedestrian accommodations. The proposed project would generally follow the FM 2186 alignment west from FM 2590 to Helium Road and then follow Helium Road north to near the Randall/Potter county line, then veer northeast on a new location alignment crossing Interstate Highway (IH) 40 and Business IH 40 to merge with the existing SL 335 near SW 9th Avenue.

The ultimate proposed controlled access facility would include four 12-foot (ft) mainlanes (two in each direction), grade separated over intersecting cross streets, two-lane frontage roads with a 12-ft wide inside lane and a 14-ft wide outside shared use lane to accommodate bicycles, and connecting ramps. The design will accommodate future expansion to an ultimate six-mainlane section. The proposed project would include 6-foot sidewalks on both sides of SL 335.

The proposed project would generally be constructed in phases. The general phasing of the proposed project would consist of the construction of the frontage roads, including the I-40 mainlane bridge at level 2, then construction of the mainlanes including the SL 335 mainlane bridge at level 3, and then finally, the construction of the ultimate condition of the I-40/SL 335 interchange based on the availability of funding.

The proposed project would require the acquisition of approximately 268 acres of additional right of way (ROW) impacting 32 parcels. Three drainage easements would be required totaling approximately 16 acres. No businesses or residences would be displaced or require relocation. A metal structure at a storage facility along I-40 would be impacted by the proposed project however the structural impact would not result in displacement or relocation of the storage facility business.

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.

Copies of the approved, final combined EA and FONSI, certification of public involvement, and supporting documentation are available for public inspection at the TxDOT Amarillo District Office at 5715 Canyon Drive, Amarillo TX  79110, (806) 356-3200 between the hours of 8:00 a.m. and 5:00 p.m. For further information, please contact John Wimberley, Environmental Coordinator, at (806) 356-3249.

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.
