b'GENERAL INFORMATIONWhen designing and building new streets and parking areas, a Curb Inlet is used to assist in the stormwater drainage of the street surface area. The Curb Inlet is typically a below ground box structure with a vertical throat opening at the street level. As the name implies, the opening is placed in the curb perimeter of the paved surface area. Also at the street level, is an iron access cover (often referred to as a manhole cover). During a rain event, stormwater drains from the street paved area into the throat opening of the Curb Inlet. This water then drains into a sewer pipe that is connected to the Curb Inlet box structure. The stormwater sewer piping is placed at a downward sloping gradient to encourage water to flow through the piping; this is also known as gravity-flow. The stormwater eventually flows into a stream, river, ocean or type of public estuary.148'
