Highland Meadows East 2nd Addition Page 2 July 13, 2004 City of Lino Lakes, Minnesota 2. As described in the previous reviews, the majority of the property's drainage is directed to the street (private drive) and the stormwater pond along the north side of the property. No additional stormwater shall be directed to adjacent properties. 3. The Contractor shall adhere to NPDES Phase II requirements prior to engaging in any grading activities. The Contractor shall also submit a Storm Water Pollution Prevention Plan (SWPPP) to the City prior to engaging in grading activities. 4. The Grading Plan must provide the catch basin rim elevations on the plan. All City of Lino Lakes standard plates for erosion control must also be provided. It should also be noted that all construction notes for both the grading and utility plans are provided on Sheet 8 (Details and Notes). The Grading and Utility Plans (Sheets 4 and 5) do not provide any reference to Sheet 8. Notes specific to each type of construction (utilities or grading) shall be provided on the respective grading and utility sheets with references as needed. 5. No geotechnical report has been submitted. According to the Anoka County Soil Survey, all existing soils are type Soderville Type A, and no wetlands exist on the site All dwelling units must meet the City's minimum requirements for building elevations (low floor) with relation to groundwater and detention basin high water elevations. This would include 4 feet above normal water levels (including groundwater and detention basins), 2 feet above design flood elevations, and 1 foot above emergency overflows. Existing information provided would suggest that the building elevations meet the minimum separations required. However, because groundwater levels often may fluctuate, it is strongly recommended that the Applicant's engineer and contractor monitor groundwater levels during the course of construction to assure compliance. In addition, the emergency overflow elevation and location for the infiltration basin should be further verified. Surrounding elevations suggest that the EOF as shown may not be correct. Utility Plans 1. As stated in the previous review memorandum, the utility plan is incomplete and must provide substantially more detail. More specifically, the water, sanitary sewer, and storm sewer will be owned and maintained by the City of Lino Lakes. Therefore, the plans must provide complete design information, including plan and profile view, invert and rim elevations, services, pipe sizes, slopes, materials, stationing, etc. All City of Lino Lakes standard plates for all utility structures, appurtenances, services, etc, must also be provided. 2. As previously mentioned in the grading comments, all construction notes for both the grading and utilities are provided on Sheet 8 (Details and Notes). The Grading and Utility Plans (Sheets 4 and 5) do not provide notes referring to Sheet 8. It is required that notes specific to each type of construction (utilities or grading) be provided on the respective grading and utility sheets.
