The purpose of the inspection was to determine whether all <br />site work has been completed in accordance with the Developer's Agreement. Based on our observations most <br />site work is complete. The pond dredging, cleaning and riprap stabilization that was outlined in our August 25, <br />2000 letter has been completed. The one item remaining is the grading of the 10:1 aquatic bench around the <br />pond at the NWL as shown on the approved grading plans. This item is important from a safety aspect as the <br />bench promotes the growth of aquatic vegetation and provides a natural barrier to children trying to enter the <br />pond. <br />The work that has been completed to date was done in accordance with City standards and is acceptable from <br />an engineering standpoint. We would recommend a reduction in the financial guarantee in the following <br />manner: <br />Original Amount <br />Previous Reduction <br />Previous Reduction <br />Proposed Reduction <br />Revised Amount <br />Letter of Credit <br />$143,408 <br />$87,758 <br />$12,750 <br />37 900 <br />$5,0©0 <br />The proposed financial guarantee should be retained until the pond grading improvements described above are <br />complete. <br />Please contact me at (651) 604-4863 if you have any questions regarding this matter. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK, & ASSOCIATES, INC. <br />Tom Kellogg <br />Cc: Mr. Paul Weinberger, City of Orono <br />2335 West Highway 36 ■ 5t.
