Brush Creek Conduit 42A Flood Control Project

NOP - Notice of Preparation
Document Description
The purpose of the project is to reduce flooding of adjacent properties along the Brush Creek Conduit 42A and across Middle Rincon Road. The proposed project would reduce localized flooding by enclosing the upstream portion of the creek in an underground conduit and/or constructing a conduit that would parallel the creek and bypass 100 year frequency storm flows through the conduit. Other than bypassing peak flows, the creek flows would be unchanged. A 100 year frequency storm has a 1-in-100 chance of occurring in any year.
