Engineering Review Page 5 July 30, 2004 Fox Den Acres ID City of Lino Lakes, Minnesota 2. It is proposed to connect 8 -inch watermain pipe from an existing stub extending from the intersection of Deerwood Drive and Fox Road. It is recommended that the size and location of the stub be verified. 3. Adequate water pressure and circulation into the proposed Development shall be verified by the Developer, as there is no loop or secondary feed available to serve the Development. A Fire Flow Analysis has therefore been provided. The Analysis has been reviewed, and the distribution system proposed is adequate. However, the 6 -inch diameter mains serving the cul -de -sacs must be sized to 8- inches per City requirements. 4. The utility plan as submitted shall be considered preliminary for review and not considered a final document for construction purposes. Final utility plans shall include the following: a. Plan and Profile sheets for all sanitary sewer, water, and storm sewer. b. Notes addressing private utilities, and erosion and sedimentation control must be provided on the Utility Plan. c. A note shall be provided on the Utility Plan stating that utility installations shall meet the requirements of the Standard Specifications of the City Engineers Association of Minnesota (CEAM) and the City of Lino Lakes. d. Information shall be provided on the Plans showing the location of individual services for sanitary sewer and water, including stationing and elevations. 5. The geotechnical report provided is not specific with regards to addressing the installation of utilities and the streets. It would appear that the soils are generally capable of supporting the proposed infrastructure with some corrections needed in some areas, particularly at low areas where wetlands are intended to be filled, and wet and substandard material may be encountered. The geotechnical report should address this further. In addition, substantial dewatering for utilities may also be necessary in many locations, depending upon the seasonal level of groundwater. 6. The Developer shall provide to the City of Lino Lakes a copy of the completed Minnesota Department of Health (MDH) Permit for watermain installation and MPCA/MCES Sanitary Sewer Permit, upon completion of the Utility Plans and prior to construction. 7. The Developer shall provide a televised inspection tape of all sanitary sewer pipes upon completion of the roadway and utilities. Any subsequent cleaning of the sewer pipes after construction shall be the responsibility of the Developer. 8. The number and location of all hydrants and gate valves shall be subject to the review and approval of the City Fire Chief. Trench and roadway compaction shall meet the requirements of the City of Lino Lakes, including 100% of Standard Proctor Density for the upper three feet directly beneath the roadway, and 95% of Standard Proctor from utility encasement zone to three feet below the surface. As stated in previous reviews, it is critical that geotechnical information and direction be followed as construction activities •9
