Title

South Drainage Channel, Channel Hardening and Erosion Control

Description

The SBIAA proposes to modify the existing man-made South Drainage by installing a concrete channel floor for the westerly 3,000 feet of channel and by installing concrete check dams and related energy dissipaters approximately every 200 feet along the eastern 2,500 feet of channel. The new channel floor pavement along the westerly 3,000 feet of the Channel has been estimated to encompass about 31,950 sf. The installation of the check dams (12) in the eastern segment has two purposes: to slow the velocity of the flow and to create ponded areas within the channel to offset the loss of existing percolation function for the western 3,000 feet of Channel that will undergo replacement of the existing soft channel bottom with a concrete bottom.
