I Zoning File #1691 & #1702 November 15, 1991 Page 4 roadways will be public. All municipal utilities will be publicly owned and maintained. To review briefly, sewer to serve Pad 1 will come from Orchard Drive on the south side of Orono Orchard Road. Water will also come from Orchard Meadows plat on the sourh side of the road. Sewer to Pads 1-12 will come from a line extending from the MWCC lift station. If the City of Long Lake is to achieve clear access to the properties to the north side of the Burlington Railroad, it will be necessary to acquire access easements via the MWCC half acre parcel. As discussed earlier, the 16" force main will have to be reloacted. The relocation will be done per the specifications of the MWCC. Please review Exhibit J. Note the comprehensive trail system approved by the City shows a trail extending northward along Orono Orchard Road to the south side of the Luce Line Trail. There is no trail extension north of the Luce Line Trail nor was it planned by the City. As the northern portions of Orono Orchard Road are surrounded by both Orono and Long Lake properties, it may be appropriate for the City to encourage discussions between the Cities' Park Commissions regarding a trail connecting to the Luce Line. This issue is raised because of comments raised in an earlier letter from an affected property owner. Dralnage/Plood Plain/Wetlands The DNR has determined the Ordinary High Water Mark of the pond/lagoon area is 9*!i3'. The "op of tne bank of the lagoon is at 947' elevation. Cook has re’^iewed the hydraulic information submitted by applicant in detemining the flood plain elevation. Tt appears the flood plain elevation is at approximately 947.3'. Planning Commission members will remember during the review of the Alan Carlson subdivision that the MCWD does not allow retention areas created for development run-off below the flood plain elevation. The rormer sewer pond area cannot serve as a retention area because ^.t is below 947.3 elevation. Retention must be provided at the higher elevations. Major portions of the surface run-off from the development will now be directed to the retention pond located within Pads 11 and 12. The 5' cut in the cul-de-sac portion of the road will take the majority of drainage from Pads 6, 5, 4, 7, 8, 9 and 10. Rear or easterly elevations of Pads 3, 7 and 8 will flow as drainage currently flows through the drainage network of the Orono Oaks plat. The rear portions of Pads 1 and 2 will flcv/ to the wetland via a culvert under Orono Oaks Drive. Pad 1, Block I's drainage will flow predominantly to the wetland to the north and the creek area. Appropriate drainage easements will be taken between the shared boundaries of Pads 11 and 12 to conveying drainage to the retention area and eventually outlet into the northeast portion
