My previous comments to them were that <br /> minimum requirements 1-9 would apply,except MR#6 for treatment. I do not see detention provided for the site. Even <br /> though they filled out the small project checklist which states that they only have to complete general info and the <br /> construction stormwater plan,the SWMM requires them to follow MR1-9 if new/replaced impervious surface is>5,000 <br /> sf and value of proposed improvements is>50%of the assessed value of existing improvements. It is on the burden of <br /> the developer to prove that their improvements are less than the 50%to be exempt. <br /> .Also,this site is in an area where we still have level of service issues in the sewer system, so detention will be required, <br /> to limit discharges to match the existing site. <br /> the filter swale (treatment) is not required and is too close to the building. The site is not suitable for infiltration <br /> because the neighboring property has a basement. <br /> -- Another comment on sheet C-5 is to make sure there is adequate clearance between proposed utilities. Also, it looks <br /> like there is some discrepancy between the elevations at SSMH1 in the plan vs profile. <br /> Let me know if you have any questions for me or want to discuss. <br /> Thanks, <br /> Arnie <br />
