• Marshan Meadows Ciiy of Lino Lakes, Minnesota April 22, 2005 5. The sanitary sewer plan provides 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 lowered to gain some additional elevation. 6. The watermain termination at the north end of the property must 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 RCV2L 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 around 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 around). This may include the capping of wells and /or removal of septic treatment facilities. All removal and disposal work shall be perfoim.ed in accordance with the requirements of the city of Lino Lakes, State of Minnesota, and any other agencies as applicable. 9ther Comments Geotechnical 1. The applicant shall be responsible for attaining any permits as required for de- watering. 2, Geotechnical information was provided in a 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 site conditions and construction requirements. Any imported fill to the site must be approved by the City Engineer. Grading and Drainage • Drainage calculations were provided for a previous review, and comments were provided as follows:
