-t24- February 26, 2003 Mr. Paul Cheme Pioneer Eng/neermg 625 Highway 10 NE Blaine,. MN 55434 Re: Pdvenwick 3rd Addition Dear Mr. Cheme: I have reviewed the eighteen sheet set of plans dated February 11, 2003 and specifications submitted for the above project. I offer the following comments: 1) There should be a minimum, of 18 inches of vertical separation between the bottom of the watermain and the top of the sanitary sewer where the water utility passes over the sanitary sewer (the City standard plate WAT 3 has been rewsed to reflect this change). Sheets 2, 3, and 5 should be. revised to reflect this. 2) Stationing should be added to all plan and profile sheets. 3) On sheet 3 of 18 there appears to: be a sewer and water conflict for the water service stubs at station 11 + 05, and at station 19 + 60. 4) West of station 20 + 50 the watermain has been extended down the center of Riverdale Drive, which may be relocated in the future through this section. An alternative mighl[ be to place the watermain along the north/south property' line and then along the south right-of-way of Highway 10. This would place less encumbrance on the vacated portion of Pdverdale Drive and the development potential of the acres to its south. Please discuss' this possibility with the. developer. 5) On sheet- 5 of 18 the sanitary sewer is short of the 7:5 feet of m~mmum cover west of station 6 and 10. It. is suggested that the sewer slope between MI-{ 4 and MH 13 be flattened to minimum slope to eliminate this deficiency. Insulation should be added wherever minimum cover cannot' be met. 0.e. north of station 10 + 50). 1 -I I I I I I I I I I I
