SECTION 1

PROJECT SPECIFIC INFORMATION

1.1 Project Overview

The United States Section of the International Boundary and Water Commission (USIBWC) requires services to replace the metal stairway at the Rio Grande City gaging station, repair the erosion along the stairway, and install erosion protection. Heavy rainfalls coupled with clearing and grading of the land adjacent to the gaging station has caused local precipitation runoff to drain towards the gaging station and erode the slope, affecting the structural integrity of the metal stairway leading to the gaging station.
