Pheasant Hills Preserve 12th Addition Page 5 September 17, 2004 City of Lino Lakes, Minnesota Storm Sewer The Standard Catch Basin detail shown shall be replaced by City of Lino Lakes standard Type 406 or Type 409 as appropriate. Other 1. A Tree Preservation Plan has been submitted as required. The Plan shall be subject to further review and approval of the City. 2. Provisions and coordination work for the extension of private utilities to the site (gas, electric, communication, etc.) shall be the responsibility of the Developer. 3. It is suggested that the street entrance radius at the end of Ruffed Grouse Road be enlarged to provide for a smoother turning movement on to the new street (i.e., incoming traffic is routed around the center island area correctly) to mitigate potential vehicle conflicts. 4. Per the requirements of the City of Lino Lakes, basement floor elevations must be at least 4 -feet above the normal water elevation and 2 -feet above the design flood level. The lowest building opening must be a minimum of 1 -foot higher than the emergency overflow elevation. According to the plan, the ordinary high water line of the surrounding wetland is 883.7. The minimum basement floor elevations as shown on the plan (888.6 and greater) would therefore appear to be adequate based on comparison to the ordinary high water mark. However, the 100 -year elevation of the surrounding wetland (as shown on the plan) is 887.6. The minimum floor elevation would therefore be required to be at least 889.6 for all units. In addition, the high water elevations of Pond 1 and Pond 2 are 888.32 and 888.61 respectively. Therefore, proposed units adjacent to those ponds must be at least 2 feet above those respective elevations. In addition to the pond and wetland elevations, a geotechnical report must be provided in order to ascertain if there are any further concerns with regards to groundwater elevations. 5. The proposed street serving the property (including the bridge) does not meet standard City requirements for width and other design requirements such as curb and gutter. In addition, a geotechnical recommendation is not available to confirm if the existing subgrade material is adequate, or if it should be removed and replaced with a suitable granular base. It is therefore expected that the street will be designated as a private street, and this must be clearly established in an Agreement between the City and the Developer (including all subsequent and future property owners). In addition, all roadway and bridge maintenance including snow plowing would not be the responsibility of the City.
