Document Description
The County is proposing to increase the capacity of the Edinger Storm Channel. The channel reach is owned by the Orange Flood Control District. The existing undercrossing at the I-405 freeway and Edinger Storm Channel and open concrete-lined trapezoid channel currently do not provide the desired level of flood protection. The project proposes to install 2 additional 66 inch reinforced concrete pipes underneath the I-405 by pipe jacking or tunneling, and a double 9 ft by 9 ft reinforced concrete box by open cutting Edinger Ave. The existing concrete trapezoid channel would be replaced with a larger capacity 20 ft wide by 10 ft deep reinforced concrete rectangular channel from I-405 to Edinger Ave and a 20 ft wide by 9 ft deep reinforced concrete rectangular channel from Edinger Ave to 1,765 ft upstream of Edinger Ave. The purpose of the project is to eliminate current flooding hazards in the vicinity of the project site. Constuction is expected to commence in April 2010 and be completed by March 2011.
