Marshan Meadows 2 March 28, 2005 City of Lino Lakes, Minnesota • • • 3. A Ghost Plat must be provided to show the road shift and lot splits to the south. The individual streets on the plans should also be identified or given names. 4. The utility plans must provide additional detail prior to approval for construction. Pipe lengths, slopes, and profiles must all be provided. 5. The sanitary sewer plan has been modified to provide for the extension of sanitary sewer to the site from an existing stub at Park Court, rather than from Stagecoach Trail. It is recommended that the extension into the property and subsequent run to the north end of the property be kept as low in elevation as possible (minimum grades) in order to maximize service to the north in the future. It would appear that the connection at Park Court may be slightly lower to gain some additional elevation. 6. The watermain termination at the north end of the property should provide an additional stub for future service and looping. 7. The property shall be subject to the review and approval of the Rice Creek Watershed District (RCWD). A copy of an approved permit and conditions from RCWD must be provided. 8. The low floor elevations of Lots 1 -5 (Block 2) do not meet the City's minimum elevation requirements with regards to the projected 100 -year elevation of the adjacent infiltration area (2 foot minimum clearance). In addition, the lowest ground opening of each structure must be at least 1 foot above the emergency overflow elevation. Emergency overflow locations and elevations are not shown on the plans. 9. Development of the property will require the demolition and removal of existing structures and facilities (above ground and under ground). This may include the capping of wells and/or removal of septic treatment facilities. All removal and disposal work shall be performed in accordance with the requirements of the city of Lino Lakes, State of Minnesota, and any other agencies as applicable. Other Comments Geotechnical 1. The applicant shall be responsible for attaining any permits as required for de- watering. 2. Geotechnical information was provided in the previous submittal. Soil borings reported that much of the site consists of areas of lacustrine soils consisting of topsoil and sandy silts. These areas are considered unsuitable for buildings and the direct support of streets and utilities. In these areas, soils will need to be excavated, removed, and replaced with compacted granular material as recommended by the geotechnical engineer. It is recommended that notes be provided on both the grading and utility plans that provide for the removal and replacement of unsuitable soils as recommended, and that the geotechnical engineer be retained throughout the duration of construction to monitor actual
