(A) It is recognized that developed areas, as compared to undeveloped areas, generally have increased imperviousness, decreased infiltration rates, increased run-off rates and increased concentrations of pollutants such as fertilizers, herbicides, greases, oil, salts and other pollutants. As new development and redevelopment continues in the city area measures must be taken to intercept and filter pollutants from stormwater run-off prior to reaching regional creeks, streams and rivers in order to preserve fishable and swimmable conditions. Through the use of best management practices (BMP), stormwater run-off will be filtered and harmful amounts of sediment, nutrients and contaminants will be removed. The project site owner must submit to the city, a stormwater pollution prevention plan (SWPPP) that would show placement of appropriate BMP(s) from a pre-approved list of BMPs specified by the city.
(B) A minimum of 25 feet width of vegetative filter strip must be provided along top-of-bank of all open ditches.
(C) Gasoline outlets and refueling areas must install appropriate practices to reduce lead, copper, zinc and polyaromatic hydrocarbons in stormwater run-off. These requirements will apply to all new facilities and existing facilities that replace their tanks.
