The city of North Bend council hereby finds that:
A. 
Stormwater and drainage problems can cause flooding, substantial damage to public and private property, and public health hazards.
B. 
High volumes of stormwater can harm aquatic resources and their habitats. The frequency, duration and intensity of peak flows can erode and undercut streambanks, scour streambeds, and deposit excessive amounts of sediments.
C. 
Stormwater pollution is a problem associated with land use and development. If stormwater is not treated, pollutants can degrade surface waters. Common pollutants carried by stormwater runoff include pesticides, herbicides, fertilizers, petroleum products, metals, pathogens, sediments and organic toxins.
D. 
Stormwater problems and dangers can be reduced or avoided if property owners and future developers follow best management practices (BMPs) when clearing land and install stormwater facilities to control and treat stormwater runoff.
E. 
In order to perform as intended, stormwater facilities must be properly designed and constructed, and periodically inspected and maintained. If this is not done, these facilities can actually become sources of pollutants to surface water and groundwater.
