Panatonni Development Page 2 August 7, 2003 City of Lino Lakes, Minnesota General 1. It is proposed to extend a street section (cul -de -sac) from Lake Drive to service the proposed development. Lake Drive is under the jurisdiction of Anoka County (CSAH 49), and the proposed street connection must be approved by the County. It should also be defined if the proposed cul -de- sac is to be a private drive or public street. 2. The wetland delineation report suggests that at least some portions of wetland, ditch, and flood plain will be filled as a result of the proposed construction. Some additional ponding areas are proposed to be created as part of the grading plan to provide for stormwater detention. The proposed grading plan will require approval of the Rice Creek Watershed District to confirm requirements for stormwater treatment, stormwater conveyance, appropriate compliance with the Wetland Conservation Act, and mitigation requirements for flood plain filling. The Developer shall provide copies of the permit application and Watershed correspondence. 3. The geotechnical evaluation reports that the underlying soils are generally sands and silty sands with the water table varying in depth. In general, the evaluation reports that the underlying soils are suitable to support the proposed building and infrastructure. However, the evaluation also states that siltier soils should be removed and replaced with drier granular material and compacted accordingly. For pavement areas, the upper 3 feet must be compacted to 100 per cent of standard proctor density. Utility installation will likely require dewatering and some placement of crushed rock where the siltier soils may not provide sufficient bedding. 4. The Landscape Plan must be adjusted as needed to avoid any plantings over utilities, especially sanitary sewer and water. Preliminary Plat 1. The preliminary plat is subject to the review and approval of Anoka County and the Minnesota Department of Transportation. 2. Drainage and utility easements (10 feet in width) must be provided around the perimeter of the property. A 40 -foot wide utility easement must be provided for the proposed sanitary sewer and water mains between the cul -de -sac and the west property line. Drainage and utility easements must also be provided for all storm sewer pipes and ponding areas. Grading Drainage and Erosion Control Plan 1. Because the site area exceeds one acre, the development falls under the new rules requiring an NPDES permit. The developer shall be responsible for obtaining this permit. Silt fence and erosion control measures are provided on the plan. • 2. There are various numbers on Sheet 2 that apparently refer to grading notes on Sheet 3. There should be a footnote identifying this referencing.
