The purpose of the Federal action is to respond to a PDM program funding request by the City of Caliente for a flood control project to address this ongoing problem. The existing Spring Heights Drive roadway cross section can generally be described as a standard 2 percent crowned road with curb and gutter on both sides. This type of roadway routes runoff water to the flow line of the curb; when the capacity of the curb is exceeded, storm water overtops the curb and flows onto adjacent private property. In addition, the existing curb includes numerous curb cuts, which further reduces the roadway's flood water carrying capacity. The primary objective of the flood control project is to reduce the recurrence interval of damage-causing flood events by increasing the flood carrying capacity of the roadway and downstream storm water system, to lessen the damage caused by flood events, and to reduce the post-flood cleanup work. 收起
