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 requirements as specified in (3)(b)(i)(A) and Sub-Item (3)(b)(ii)(A) of this Rule, otherwise a minimum 30 foot vegetative buffer for development shall be required along all perennial waters indicated on the most recent versions of U.S.G.S. 1:24,000 (7.5 minute) scale topographic maps or as determined by local government studies. Nothing in this Rule shall stand as a bar to artificial streambank or shoreline stabilization; (H) No new development shall be allowed in the buffer; water dependent structures, or other structures such as flag poles, signs, and security lights, which result in only de minimus increases in impervious area and public projects such as road crossings and greenways may be allowed where no practicable alternative exists. These activities shall minimize builtupon surface area and avoid channelizing stormwater; (I) No National Pollutant Discharge Elimination System (NPDES) permits shall be issued for landfills that discharge treated leachate; (ii) Critical Area Nonpoint Source and Stormwater Pollution Control Criteria: (A) Low Density Option: new development shall be limited to either no more than one dwelling unit of single family detached residential development per acre (or 40,000 square foot lot excluding roadway right-of-way), or 12 percent builtupon area for all other residential and nonresidential development; stormwater runoff from the development shall be transported by vegetated conveyances to the maximum extent practicable; (B) High Density Option: if new development exceeds the low density requirements specified in SubItem (3)(b)(ii)(A) of this Rule, then engineered stormwater controls shall be used to control runoff from the first inch of rainfall; development shall not exceed 30
