Snyders Site <br />File No. 139GEN-2567 <br />Dear Mike: <br />We have completed u preliminary review of the grading and utility plans (Dated 3/13/00) for the proposed <br />Snyders siic in Navarre. The site is located on the east side of Shady wood Road (CSAH 19) and nortli of <br />Navarre Lane and Shorulinc Drive (CSAH 15). We have not completed a final revievk' because of two <br />engineering issues that will detennine whether the plan is constructable on this site. The items are as follow: <br />• Ponding; The pond design is very tight. To accommodate the flows from the contributing <br />drainage .irca thi pond must be constructed exactly as shown on the grading pl;tn and no sttiallcr. <br />We recommend that the pond volumes be verified after construction. <br />• Retaining Walts: This appears to be the more concerning of the two items. The wall bordering <br />the pond exceeus 20-feei in height in some locations. A retaining wall of this magnitude requires <br />a detailed design and soils ona1y.sls which we have not received at the lime of this vyriilng. Phil <br />Caswell, from our structural group, perfurmed ii preliminary review of the retaining wall part of <br />the submittal. Wc have attached hi.s comments for your review*. <br />Our primary concern i.s tlijt if the final design of the walls requires more room to construct than is currently <br />shown on the grading plan, then cither the pond becomes .smaller or the piuking lot und/or building arc reduced <br />in size. As previously stated, the pond cannot be made any smaller. The developer may need to make some <br />revuiunv to ihc site plan if tire proposed retaining walls need to be revised. <br />Once the developer provides a buildable grading plan (or documentation (hat the cun-ent pUm is) we will <br />complete our finut situ plan review. At thi.s lime we will address issues such as pond outlet piping, parking lot <br />grade.s. Iniil sections, etc. <br />Pte;ise contact me at (651) 604>486.3 if you have any que.stions regarding this matter. <br />Yours very truly, <br />BONHS rkoO. RO.SF.NI-. ANDERLIK & ASSOCIATES.
