The city council makes the following legislative findings:

    (1)    Land development projects increase impervious surfaces resulting in increased stormwater runoff rates and volumes, flooding, stream channel erosion, sediment transport and deposition, and increased quantities of water-borne pollutants.

(2)    Stormwater runoff, soil erosion and non-point source pollution can be most cost-effectively controlled and minimized through land use regulation and preventative measures aimed at reducing stormwater runoff from development sites.

    (3)    The regulations set forth in this article reasonably reduce the harm caused by land development projects and are in the public interest.
