I have the following <br />comments/recommendations: 'i' '. <br /> <br />~' :1 . <br />1. Recommend an 18" reinforced CQAcrete cUlvert under fue entraiJce road rather than <br />12" RCP shown. <br /> <br />, <br /> <br />2. 'The sanitary sewer manhole invert eleviltions (IE) shown are incorrect and, should be <br />revised to the following: .' . <br /> <br />ME 1 IE 894.02/893.92 <br />ME 2 IE 894.70/S94.60 <br />ME 3 IE 89553 <br />ME 4 IE 895.54 <br /> <br />3. The two 6" water valves in the parking lot should be moved south approximately 20' <br />to either side of the 6x6 tee. <br /> <br />4. Place 10 cubic yards of riprap at the stann sewer outlet to the pond. . This should be <br />shown on the grading plan. . . <br /> <br />5. Show silt fence around the entire site to prevent erosion into the pond, county ditch, <br />and Clearwater creek. <br /> <br />2335 West Highway 36 . St. Paul, MN 55113. 651-636-4600 .
