      (1)   All land-disturbing activities and all development or redevelopment activities that disturb an area greater than or equal to one acre.
      (2)   Sites that are smaller than one acre shall also be covered by these regulations if they are a part of a larger common plan of development or sale.
      (3)   Stormwater management facilities will be required for any nonresidential development for which the area paved and under roof is equal to or greater than 10,000 square feet.
   (B)   These regulations shall apply to land-disturbing activities within the jurisdictional boundaries of the City of Madisonville designated by the Kentucky Division of Water for coverage under the KPDES SMS4 permit.
   (C)   Unless included in exemptions listed in § 54.05(F) or a waiver granted, all development occurring within the city and subject to this chapter shall provide for properly sized stormwater conveyance and water quality facilities and shall contain on-site, or provide off-site, stormwater management facilities capable of controlling peak discharge rates for selected design storms to at or less than pre-developed conditions, and water quality control structures capable of managing the stormwater runoff quality produced from an 80th percentile rainfall event under post-construction conditions.
   (D)   The use of other methods of controlling peak discharge rates and pollutant removal, such as bio-retention swales, infiltration ditches, hydrodynamic separators, and created wetlands may be required by the city, in its sole discretion, for new and redevelopment projects that are subject to the land development requirements of this chapter. Additionally, the city will promote conservation measures such as buffer strips and greenways as acceptable techniques toward the protection and improvement of local waterways.
