Mr. Boryczka <br />Page 5 <br />In summary, because the Roseville City Code does not have specific standards for Biofiltration, <br />we look to the Best Management Practices for Bioretention published by MPCA as a part of its <br />Stormwater Manual dated September 2006, which it recommends that local governments follow. <br />The Plan submitted for Oak Acres may not meet the recommendations and requirements of the <br />MPCA, particularly in the areas of soil infiltration capacity, pretreatment of discharge, <br />vegetation plan and setback requirements. It also may not meet the requirements of City Code <br />Section 1016.23 which requires an applicant to submit sufficient information regarding soil <br />limitations so that the City can determine whether each lot in a subdivision is suitable for the <br />proposed purpose. If the applicant has failed to provide sufficient soil data necessary to <br />complete a full review of the Bioretention facility, TEI believes that the City should deny the <br />plan as submitted until the applicant can prove that the Bioretention facility meets City Code and <br />MPCA standards. <br />Very truly ours, <br />Steven W.
