• Mr. Michael Grochala April 24, 2006 Page 2 3. Proposed grading around Buildings 9 and 10 must be revised to incorporate an access route to Pond 3, as stated previously. The proposed grading, as currently shown, will not allow vehicle access to Pond 3. 4. The sidewalk between Buildings 13 and 14 has a slope that is 20% or greater. Slopes on sidewalks cannot exceed 5 %. 5. The sidewalk at the southwest corner of Building 7 has a slope of 10 %. Slopes on sidewalks cannot exceed 5 %. 6. The grading between Building 1 and CBMH 110, as shown, appears to be flat. The rim elevation of CBMH 110 could be lowered to provide positive drainage from the sidewalk to the catch_basin. 7. It appears retaining walls will be required for some of the buildings fronting Village Drive, Town Center Parkway, and Woods Edge Boulevard. 8. Two rows of silt fence should be installed along the existing wetland, as additional protection at the base of the proposed slope. 9. Emergency overflows should be identified for interior drive aisles. Slope stabilization in these areas may be required. 10. Erosion control blanket is required where storm sewer outlets intersect pond slopes. • Preliminary Sanitary Sewer and Water Main Plan (Sheet C4.0) • 1. Note 10 on the plan sheet indicates that hydrants are to be located 5 feet behind back of curb. City standards require hydrants to be located 4 feet behind back of curb. Gate valves should be shown where required on the plans (hydrants, wet taps, etc.). 3. Show all water service lines coming off of Woods Edge Boulevard as beginning at the right -of -way line. Stubs will be provided "by others" to the right -of -way line. 4. The hydrant leads between Buildings 11 and 12 and Buildings 13 and 14 shall be 6 -inch diameter rather than the 8 -inch diameter as shown. All hydrant leads shall have 6 -inch diameter pipe. 5. Sanitary manhole 2 and CBMH 209 are located too close together to be constructed as shown. 6. The size of the water line on the west side of Building 14 is not labeled. 7. The westerly invert elevation for sanitary manhole MH -B in Woods Edge Boulevard shall be revised to match the elevation of the north -south invert. 8. Show the sanitary sewer services off of Woods Edge Boulevard as connecting to stubs "by others" at the right -of -way line. 9. The applicant should flatten the pipe grade from sanitary MH -A to MH 9 to minimum grade and should steepen the pipe grade from MH 9 to MH 10 to increase cleanout velocities in the dead end run of pipe. Having the dead end run of pipe, with its lower flows, at a slope greater than minimum will aid in keeping the pipe cleanout velocities higher. TRECEVED APR 2 5 2006 CITY OF LINO LAKES
