The existing drain has beocme clogged with debris as a result of the 2007 Santiago Canyon Fire. The blockage is located in the drain section downstream of a manhole on Crystal Canyon Road. The project involves flushing the clogged drain with a hydrojet and removing the mud and debris with a vacuum truck. A containment system will be consturcted around the mouth of the outlet to prevent the discharge of mud, rock, and debris into the created wetland.
