Mr. Jeff Smyser • July 6, 2001 Page 2 • • culvert or orifice for rate control. This is not practical and will not be accepted, because an orifice this size is prone to clogging. 2. The City of Lino Lakes requires that the storm sewer for commercial areas must be designed and sized to accommodate a 10 -year storm event. These calculations have not yet been provided for review. 3. The grading plan includes the proposed storm sewer. To aid the City with our review additional information must be provided for the storm sewer including the size, length, and slope of the pipe. 4. Included in the storm calculations that were received in the previous submittal was the use of a broad crested weir. The location of the weir is still not shown on the grading plan. 5. Included in the plan are the locations of several bio- retention basins. The bio- retention basins appear to be located primarily in the parking lot islands and medians, which are surrounded by concrete curb and gutter. Additional information must be provided that illustrates how the storm water runoff from the site enters the bio - retention basins. 6. The City of Lino Lakes requires that the construction details must be included in the plan set. Some of the details that are needed are erosion control measures, storm sewer manholes, catch basins, and outlet control structures. 7. To date the Rice Creek Watershed District has tabled the review of this project. They have not granted a TWAAFA nor have they approved the wetland replacement. The submittal for the site is still lacking information. I have enclosed a copy of the fax from the Rice Creek Watershed District, which lists in detail the information that is missing. The cutoff for information to be received by the Rice Creek Watershed District, if it is to be included at the next meeting of the Board of Managers, is July 12, 2001. The next meeting of the Board of Managers is June 25, 2001. As of today, not all of the information had been received. Sanitary Sewer and Watermain Plan 1. The proposed utility plan includes the connection to the City watermain on 77th Street and on Lake Drive, as well as a connection to the sanitary sewer on Lake Drive. Currently, there is an existing 21" sanitary sewer main and a 12" watermain that runs parallel to Lake Drive on the east side. The existing watermain on 77th Street is 8 ". In my review of the previous submittal I stated that the utility plan must include the length and slope of the proposed sanitary sewer. The current submittal does include this information.
