Olson <br />city of Orono <br />Box 66 <br />Crystal Bay, Mn. 55323 <br />Attn: Ms* Jeanne Mabusth <br />Re: File No. 139-764 <br />Dear Jeanne, <br />Ue have reviewed the storm water runoff Information submitted by the Calvary <br />Memorial Church at 2420 Dunwoody Avenue to determine the effect of the addi­ <br />tional hardcover* <br />The drainage calculations as submitted are acceptable and provide for pond <br />storage of 0*116 acre feet with a 9*3 cfs outlet capacity* The proposed de­ <br />sign does not adequately justify an Increase In hardcover as the pond would <br />not Improve the percolation rate Into the ground but would control the rate of <br />runoff to that which exists at the present time* <br />If the variance to the hardcover ordinance Is to be granted, we would recom­ <br />mend a pond designed to Improve the percolation rate or slow the discharge of <br />the additional runoff* This detail could be adequately worked out with the <br />developer and City staff* It would not be possible to totally mitigate the <br />effect of the additional hardcover but a plan could be developed to Improve on <br />the present proposal* <br />Yours very truly. <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Glenn R* Cook <br />GRC:11 <br />6257b <br />Pi <br />TO: <br />FROM: <br />DATE: <br />SUBJECT: <br />Zoning C <br />Applicat <br />Ordinanc <br />0-50' - <br />50'-100' <br />List of <br />Exhibit <br />Exhibit <br />Exhibit <br />Exhibit <br />Exhibit <br />Exhibit <br />Exhibit <br />Exhibit <br />Property <br />with loc <br />shoreline <br />placemen <br />build a <br />be able <br />subject <br />use of tl <br />the exte] <br />Staff se< <br />location <br />with the <br />I would : <br />1.
