About this file
This file contains engineering drawings and technical specifications for stormwater management details related to a temporary drainage opening in the Broward County Water Preserve Areas Project, Contract 2. The drawings show three cross-sectional views at 1"=20' scale depicting conceptual designs for a temporary drainage opening excavation, bentonite amended soil backfill at a slurry wall, and slurry wall treatment prior to backfill placement.
The drawings specify requirements for a temporary drainage opening through a slurry wall to convey stormwater flow from Canal A/5 and Canal B/4 to the C-11 Canal. Key technical details include embankment transition slopes of 3:1, minimum 15-foot dimensions for excavation areas, cement paste application requirements for the slurry wall surface, and elevation specifications ranging from 0.0 to 18.8 feet for various components. The document includes five detailed general notes covering contractor requirements for drainage opening construction, surface preparation, backfilling procedures, and cement paste application standards in accordance with Section 31 42 00.
