Highland Meadows East 2nd Addition Page 2 February 26, 2004 City of Lino Lakes, Minnesota 2. 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. However, stormwater not directed to the pond must not flow to adjacent properties, particularly along the south side of the property. The property must either be graded to swale to the 21 -inch RCP, or storm sewer shall be installed along the property line to intercept the drainage. 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. Only the 100 -year computations have been submitted. The 1 -year and 10 -year computations must be submitted. 5. Existing condition curve numbers and time of concentrations are acceptable. 6. Proposed conditions computations should assume Type "B" soils in all disturbed areas when computing curve numbers. 7. Outlet control structure details are required. Skimming must be provided for at least the 1 -year storm event. 8. No geotechnical report has been submitted. Groundwater levels are therefore unknown. Low floor elevations must be a minimum of 4 feet above the high groundwater and pond normal water elevations. 9. All requirements and conditions of the RCWD shall apply as provided. 10. 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. Groundwater levels must be verified to adjust any elevations as may be needed. Additional Comments: 1. The proposed street serving the property is designated as a private drive. It is therefore presumed that the utilities (sanitary sewer and water) shall be private, and that the property owners or local association shall be responsible for owning and maintaining both the street and utilities. This shall include all maintenance and replacements as needed, including snowplowing and street repair. However, all public utilities shall be constructed per the standards and requirements of the City of Lino Lakes. This should all be spelled out very clearly in the City/Developer Agreement, and a written agreement designating responsibility to the homeowners or local association as appropriate
