• Panatonni Development Page 2 September 17, 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. The proposed cul-de-sac serving the site is intended to be a public street. 2. The July 1, 2003 letter to Polaris Group from RCWD states that the wetland delineation has been reviewed and accepted. 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. A geotechnical evaluation previously provided reports that the underlying soils are generally sands and silty sands with the water table varying in depth. In general, the evaluation states 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. It is recommended that a geotechnical engineer be retained and consulted accordingly through the duration of construction. 4. Landscape Plans (L1, L2, and L1.1) were provided in a previous submittal. In the August 20 review memorandum, it was stated that the plan needed to be adjusted to avoid any plantings over utilities, especially sanitary sewer, water, and storm sewer. Revised landscaping plans must be submitted for further review. 5. The Tree Inventory and Tree Preservation Plans provide number identifications for the many trees on the site. Separate sheets for the tree sizes and types must be provided. 6. Retaining walls are shown at some locations on the site plan. The detail sheet should provide a standard detail for the type of wall and construction. 7. The developer shall be responsible for obtaining an NPDES permit prior to construction (see additional note under Grading and Drainage). 8. A right turn lane on CSAH 49 is proposed for the southbound approach to the site, and a pavement section and length are provided. The length of this turn lane and taper may be shorter than the standard required by Anoka County. The proposed shoulder/turn lane section and length must therefore be approved by Anoka County, and copies of approval correspondence provided.
