Public Notice           Project Plans          Alternative Analysis           Mitigation Proposal

The applicant requests authorization to permanently impact approximately 24.090 acres of emergent wetlands, 0.789 acres of scrub-shrub wetlands, 3.216 acres to tidal mud flats, 1.846 acres of estuarine wetlands, 3.216 acres to tidal sand flats, and 0.004 acres of open water. Temporary impacts include 22.728 acres of emergent wetland, 0.272 acres of scrub-shrub wetland, 10.055 acres to tidal mud flats, and 0.217 acres to open waters. The Project proposes widening approximately 13 miles of Texas State Highway 4 (SH 4) from the existing 2-lane roadway to a 4-lane divided roadway with two, 12-foot travel lanes and an 8- foot paved shoulder in each direction, with a 12-foot flush paved median separating opposing traffic. At the western end of the project, the 2-lane roadway would transition into a 3-lane roadway for a length of approximately 1,500 feet, with two, 12-foot lanes in the westbound direction and one, 12-24-foot lane in the eastbound direction, separated by a 12-14-foot median, before transitioning into the 4-lane roadway. Existing culverts would be extended to accommodate the widened typical section and turn lanes would be added at some intersections. The Project would be fully located within the existing SH 4 ROW. An 8-foot bike path with a 4- to 6-foot grass separation from the outside travel lane would be constructed on the south side of SH 4 for approximately 3.75 miles from Quicksilver Avenue (the southern end of the Rio West development) to LBJ Boulevard (the northern end of Boca Chica Village).
