We.have <br /> also included the survey data collected by City crews on July 12, 2001. For reasons noted above we <br /> recommend that the trail be reconstructed with a maximum grade not to exceed 5%. We further recommend <br /> that the trail grade at the approach to Olive Avenue not exceed 2%and that sight distances at this intersection <br /> be improved through grading or landscaping activities. <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 /> Attachments <br /> Cc: Greg Gappa, City of Orono <br /> 2335 West Highway 36 St. Paul, MN 55113 651-636-4600 Fax: 651-636-1311 <br />
