A location within the drainage reach downstream of the subject site consisting of a channel section, drainage swale, bridge, box culvert, storm sewer or other conveyance facility or structure having a conveyance capacity which would be exceeded by stormwater runoff from a 10-year frequency, 24-hour duration storm under existing land use conditions; or an existing structure or building located downstream of the subject site which has its lowest floor elevation less than one (1) foot above the maximum elevation in an adjacent channel attained by the 100-year frequency, 24-hour duration storm, assuming existing land use conditions with the proposed ultimate development of the subject site in place. The conveyance capacity of a structure operating under inlet control conditions shall be determined with a maximum headwater to diameter ratio (HW/D) of 1.50 or with a headwater elevation equal to the top of curb, whichever is less.

Stormwater control devices may be included as an integral part of the erosion control plan.

The plan submitted by the developer which incorporates the designs and management controls of the Stormwater Pollution Prevention Plan. Such plan need only cover the tract of land for which land disturbance activities will occur.

Removing, clearing or scalping material such as roots, stumps, underbrush or sod.

A channel formed in the existing surface topography of the earth prior to changes made by unnatural conditions.

The use of developed land for any purposes other than for a single-family residence or a multiple-family building.

A lot, tract or parcel of land, or a contiguous combination thereof, where grading work is performed as a single unified operation.

A closed conduit or open ditch, natural or specifically constructed, for conducting or conveying collected stormwater. Conduits and paved open ditches are termed improved; unpaved ditches are termed unimproved.

All drainage facilities used for collecting and conducting stormwater to, through and from drainage areas to the points of final outlet including, but not limited to, the following: conduits and appurtenant features, canals, ditches, streams, gullies, flumes, culverts, streets, gutters and pump stations.

Guidelines, delineating minimum acceptable design criteria, intended primarily for use by land developers and/or engineers in the design of storm drainage systems and sediment and erosion control practices.
