Ms. Katie Larsen <br />March 27, 2013 <br />Page 2 <br />of the drive to the north side of the drive. The City would prefer to see the access drive <br />have a crown located along the center of the drive and drainage collected in catch basins <br />on either side of the roadway. <br />3. The plans include notes regarding seeding and sodding; however, the areas proposed to <br />be vegetated are not shown. Please add to the plans the locations of the proposed <br />vegetation. <br />Utility Plan Comments: <br />1. A hydrant is required at the end of the 8 -inch watermain stub for fire protection and <br />flushing purposes. <br />2. The grate shown on the storm sewer catch basin detail does not match the notes for CB <br />#101 and CB #102 shown on the utility plan. <br />3. The existing sanitary sewer shown within Otter Lake Road needs to be extended south to <br />the existing manhole located within CSAH 14. <br />4. Sanitary sewer manhole #1 currently shows an inside drop. An inside drop is not <br />permitted and an outside drop must be installed per City standards. <br />5. The sanitary sewer stub "A" invert elevation is incorrect. Based on the slope and length <br />of the proposed stub the invert elevation should be 905.28, not 899.52. <br />6. The proposed slope of the storm sewer pipe from storm stub "B" to CB #101 is not <br />correct. Based on the proposed inverts and length of pipe the slope should be 3.07 %, not <br />1.00 %. <br />7. The proposed slope of the storm sewer pipe from CB #101 to FES #100 is also not <br />correct and does not match the inverts and length of pipe shown. <br />General Comments: <br />1. A SWPPP plan is required for the site and must be included with the plans. <br />If you have any questions or need additional information, please let me know. <br />S:\Plamning & Zoning Board \Packets\Packets - 2013\April 10, 2013 \7A -Main Street Shoppes \City Engineer Letter - 032713.doc <br />• <br />• <br />• <br />
