A. 
Best Management Practice (BMP).
With reference to the Urban Drainage and Flood Control District's Drainage Criteria Manual, Volume 3, a BMP can be a device, practice, or method for removing, reducing, retarding, or preventing targeted storm water runoff constituents, pollutants, and contaminants from reaching receiving waters.
B. 
Storm Sewer System.
Includes but is not limited to the following: a conveyance or system of conveyances, which includes roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains owned by the city and/or owned privately.
C. 
Storm Water Management Plan (SWMP).
Refers to a plan that details the erosion, sediment and waste control plans required for applicable development sites.
D. 
Land Disturbance.
Any activity that results in a change in the existing land (both vegetative and nonvegetative). Land disturbing activities include, but are not limited to, construction activities such as clearing, grading, excavation, demolition, installation of new or improved haul roads and access roads, staging areas (if they are disturbed), stockpiling of fill materials, and borrow areas. Compaction that is associated with stabilization of structures and road construction is also a land disturbing activity.
E. 
Final Stabilization.
The condition reached when all ground surface disturbing activities at the site have been completed, and for all areas of ground surface disturbing activities a uniform vegetative cover has been established with an individual plant density of at least seventy percent (70%) of predisturbance levels, or equivalent permanent, physical erosion reduction methods have been employed.
