Marshan Lake Townhomes Review Page 2 August 6, 2004 City of Lino Lakes, Minnesota • requirements. Silt fence and erosion control details are provided on the plans and shall be installed accordingly. 7. Per the Survey and Existing Conditions Plan previously submitted, several buildings including houses, barns, sheds, and a garage all exist on the site. Demolition, removal, and grading of the site will therefore be required. The applicant will be responsible for the complete removal of all buildings, foundations, underground and above ground items, capping of any existing utility connections and wells, and removal of any underground, fuel storage or septic systems that may exist. All debris and unsuitable material must be removed from the site. Any material imported to the site must be approved by the City Engineer. 8. Geotechnical information was previously provided. As previously stated, additional excavation of fine alluvial silts and replacement with compactable granular material may be required for construction of the buildings and private drives. Groundwater levels may also necessitate dewatering for the utility installations. Any imported topsoil, fill material, or granular materials for roadway and building foundation (material and source) must be approved by the City Engineer. • 9. The preliminary plat provides for standard drainage and utility easements (10 feet in width) around the perimeter of the property as required. In addition, 44 foot wide drainage and utility easements covering the two private driveways are also provided. As previously stated, the driveway easements as shown shall also be dedicated to include access in addition to the drainage and utility dedication. 10. A revised utility plan must be received for review and approval. A field exploration was conducted on July 30, 2004 to verify the size and location of the existing utility line extensions to the site. The site exploration confirms that three sets of sewer and water services ((3) X 4" water services and (3) X 6 "sanitary sewer services) extend from Aqua Circle. As stated in the previous review, the City will not allow any main line utility extensions from the existing 4" service stubs. The proposed watermain will therefore be required to connect directly to the existing 12" main, or to a 6" hydrant lead if available (hydrant would require relocation). The existing 6" stubs can be connected to with 8" lines, provided that a manhole is installed at the connection point. No sanitary sewer main line cleanouts will be allowed. All utility extensions and streets /driveways shall be considered private and will not be owned or maintained by the City of Lino Lakes. This must be detailed in an Agreement between the City and the Applicant. The utility plan shall also show the specific locations of individual valve boxes and their service termination points (between street and building). Individual sanitary sewer and water services must also meet minimum separation distances. • 11 As previously stated, all utility work shall be performed in accordance with the City of Lino Lakes, City Engineers Association of Minnesota (CEAM) Specifications, and City of Lino Lakes building permit requirements. Water pipe and appurtenances shall meet the requirements of the City of Lino Lakes, and as follows: Hydrants - Waterous Pacer WB -67; Valves - Mueller A2370 -20 or equal. DIP pipe shall be Class 52. All sanitary sewer service pipes shall be SDR 26 or Schedule 40. The location and number of hydrants will be subject to the review of the City Fire Chief. Safety and traffic control during construction must be provided in accordance with the State of Minnesota Manual of Uniform Traffic Control Devices (MUTCD).
