In any review, approval, or permit process, the following general and specific standards shall be addressed:
(A) When possible, existing natural drainage ways, wet lands, and vegetated soil surfaces shall be used to convey, store, filter, and retain stormwater runoff before discharge to public waters.
(B) Development must be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. Disturbed areas shall be stabilized and protected as soon as possible and facilities or methods used to retain sediment on the site.
(C) When development density, topographic features, and soil and vegetation conditions are not sufficient to adequately handle stormwater runoff using natural features and vegetation, various types of constructed facilities such as diversions, settling basins, skimming devices, dikes, waterways, and ponds shall be used. Preference must be given to designs using surface drainage, vegetation, and infiltration rather than buried pipes and man made materials and facilities.
(D) Impervious surface coverage of lots shall not exceed 25% of the lot area.
(E) When constructed facilities are used for stormwater management, they must be designed and installed consistent with the field office technical guide of the local soil and water conservation districts.
(F) New constructed stormwater outfalls to public waters must provide for filtering or settling of suspended solids and skimming of surface debris before discharge.
