Panatonni Development Page 3 August 7, 2003 City of Lino Lakes, Minnesota 3. A typical section (pavement section) must be provided for the proposed street entryway (bituminous thickness, gravel base thickness, etc.). The street is identified as 40 feet in width with B618 concrete curb and gutter. Termination and matching of the curb into CSAH 49 must be coordinated with Anoka County. 4. The slope and grade of the cul -de -sac gutter is identified as 0.6 %, but appears to be much flatter based on the proposed spot elevations. It is recommended that the grades be further reviewed and adjusted as needed to provide proper drainage. 5. Any imported topsoil, fill material, or granular materials for roadway and building foundation (material and source) must be approved by the City Engineer. 6. A note shall be provided that any clearing of trees shall be performed in accordance with the requirements of Mn/DOT 2101. 7. All grading shall be confined to the property. No additional runoff from the site shall enter upon neighboring properties. If grading requires any work into the adjoining property, the Contractor shall be responsible for obtaining authorization as needed. • 8. All storm sewer structures and types identified should also refer to City of Lino Lakes standards. In • addition, flow direction arrows on the storm sewer lines are needed. 9. A right turn lane on CSAH 49 is proposed for the southbound approach to the site. The proposed shoulder /turn lane section shown must be approved by Anoka County. 10. The graphic for TuffTurf does not show up clearly on the plan and should be adjusted accordingly. 11. The Mn/DOT Specification for turf restoration (2575) and a seed mixture approved by the City must be specified. Drainage Calculations 1. Emergency overflow locations and elevations for the ponds and infiltration areas must be identified. 2. Proposed ponds 1, 4, and 5 have proposed pond bottoms below the groundwater level. 3. High water elevations for the wetlands are not shown. The information submitted does not indicate if the wetland elevations will rise or be impacted by the proposed construction. In addition, the school pond must be modeled for existing and proposed conditions. The existing conditions appear to be correct while the proposed condition must be revised accordingly. 4. The wetland and Pond 5 should be modeled separately (not combined) to determine their respective flood elevations.
