expansions of existing development of up to 70 percent builtupon surface area (the "10/70 option") in addition to the new development approved in compliance with the appropriate requirements of SubItem (3)(b)(i)(A) or SubItem (3)(b)(i)(B) of this Rule. For expansions to existing development, the existing builtupon surface area shall not be counted toward the allowed 70 percent builtupon surface area. A local government having jurisdiction within the watershed may transfer, in whole or in part, its right to the 10/70 option land area to another local government within the watershed upon submittal of a joint resolution and review by the Commission. When the water supply watershed is composed of public lands, such as National Forest land, local governments may count the public land acreage within the watershed outside of the critical area in calculating the acreage allowed under this provision. For local governments that do not choose to use the high density option in that WSII watershed, each project shall, to the maximum extent practicable, minimize builtupon surface area, direct stormwater runoff away from surface waters, and incorporate best management practices, as defined in Rule .0202 of this Section, to minimize water quality impacts. If the local government selects the high density development option within that WSII watershed, then engineered stormwater controls shall be employed for the new development; (F) If local governments choose the high density development option that requires stormwater controls, then they shall assume ultimate responsibility for operation and maintenance of the required controls as outlined in Rule .0104 of this Subchapter; (G) A minimum 100 foot vegetative buffer shall be required for all new development activities that exceed the low density option requirements as specified in
