Please see the following comment. A. Site Development Plan (SDP201300036) It appears that you are going above the previously compromised impervious amount to be treated. The biofilter is already sized for the maximum allowed impervious area for treatment. The approved biofilter's size was reduced 10 %, or 1354 sf, per our discussion on 3/7/13. The additional impervious area from proposed parking spaces will require a different BMP for treatment. This new BMP will give you the opportunity to treat the 27,061 sf of untreated impervious area. Include the 10% untreated area in water quality calcs. Sincerely, Michelle Roberge
