Simplify the drainage and utility easements around the ponds and along the west side of the <br />development by squaring them off and combining them with nearby and adjacent drainage and <br />utility easements. <br /> <br />3. Provide an easement for the shared hydrant service lead crossing over between both lots 1 and 2 <br />of block 1. <br /> <br /> <br />Existing Conditions, Erosion, and Sediment Control <br /> <br />1. Submit erosion control plans with final plat/construction plan submittal. <br /> <br /> <br />Site Plan <br /> <br />1. Provide 6’ wide concrete walks per City standards where 5’ concrete walks are currently shown. <br /> <br />2. Show necessary removals for the installation of the proposed utilities along Kenzie Terrace/ CR <br />153. <br /> <br /> <br />Grading Plan <br /> <br />1. Structural calculations for the proposed retaining walls greater than 4.0’ in height need to be <br />submitted for review prior to construction of the walls. The submittal will need to include: <br />a. Certification of a qualified MN licensed professional <br />b. Soil boring logs and geotechnical recommendation for support <br />c. Identify the type of material for the wall and design details <br />d. Provide details of the wall construction <br />e. Provide a safety railing or fence above the wall <br /> <br />2. Driveway ramps into the buildings should not exceed 10%. <br /> <br />3. The outdoor patios and plazas with the buildings do not appear to have any slope. How will <br />surface drainage be accomplished? <br /> <br />4. The NWL of the southwestern stormwater pond is the same elevation as the Multi-residential 1 <br />garage floor (912.0). <br /> <br />5. The HWL of both ponds exceed the garage levels of the connected buildings. <br /> <br />6. Demonstrate how the proposed improvements accommodate for the current ground water <br />elevations. <br /> <br />7. There are areas where the slopes shown do not meet the minimum required 2% or exceed the <br />maximum allowed 3:1. <br /> <br />8. The driveway elevations at the top of the ramps need to be raised to achieve a minimum 1’ <br />freeboard above the adjacent road’s EOF. <br /> <br /> <br />Sanitary Sewer and Watermain <br /> <br />1.
