San Antonio River and Tributaries, Texas Foundation Report, San Pedro Creek Tunnel and Shafts by PDF Summary

Book Description: This project is part of a broader San Antonio Channel Improvement Project. The latter is a flood control project for the upper San Antonio River and four tributaries--Martinez, Alazan, Apache, and San Pedro Creeks. The subject of this report is a tunnel constructed on San Pedro Creek. The tunnel follows the course of San Pedro Creek in an easterly arc between Interstate Highway 35 on the north and Guadalupe Street on the south. The tunnel slopes downstream at a gradient of .002 from an invert depth of 117 feet (elev. 506) at the inlet to 145 feet (elev. 494) at the outlet. The lining is 12-inch thick precast concrete which gives an inside tunnel diameter of 24 feet 4 inches. This report describes the foundation conditions encountered during the construction of the subject tunnel and shafts. It is also intended to be a consolidated record of the foundation related construction operations and an information source for future reference.
