SECTION 6. Chapter 5, Environmental Regulations, Article 1, General Provisions, Section 5.1.1.2, Erosion Control Standards, is amended to read as follows: 5.1.1.2 Erosion Control Standards (a) Standards for Overland Flow and Natural Drainage: (1) Natural drainage patterns shall be preserved whenever possible. Drainage objectives can best be accomplished by leaving portions of a subdivision in an underdeveloped and natural state and located to receive runoff from the developed areas for purposes of unchannelized, overland flow. (2) The loss of the pervious character of the soil shall be limited in order to prevent erosion and attenuate the harm of contaminants collected and transported by stormwater. (3) Open surface drainage through grass -lined swales shall be utilized if possible. (4) Drainage swales and other areas used for conveying stormwater runoff from developed areas shall be located to avoid sinkholes, faults and fractures to the greatest extent practicable. (5) Construction of enclosed storm sewers and impervious channel linings shall be permitted only when the Engineering Director, on the basis of competent engineering evidence, confirms that the storm sewers or impervious linings are the only justifiable option available. These systems shall be designed to mitigate their impact on water quality through the use of approved control strategies to control sediment, neutralize contaminants and dissipate energy by the-use of multiple smaller outlets, whenever practical,"by locating discharges to maximize overland flow and by any other strategies that will accomplish the objectives defined and discussed in this Article. (6) Point discharges. Point discharges of runoff shall be dissipated to sheet flow conditions. (7) Necessary stormwater drainage systems and culverts shall be designed to mitigate the impact of erosion and stormwater runoff on water quality through the use of approved control strategies to control sediment and dissipate energy and through the use of multiple smaller outlets whenever practical and by locating discharges to maximize overland flow.
