Ms. Katie Larsen 9/3/2025 Page 4 Turf maintenance access shown on revised plans. Turf maintenance access should not be located within the septic areas (see Lot 4). The turf maintenance access location has been adjusted to be out of the septic area. Access is not a problem in this location, but in any case, access paths from the driveway have been noted on the sides of the basin. 6.Plans shall show rip rap or alternative stabilization for drain tile underdrain outlets. Riprap splash pad is indicated on plans for underdrain outlets. Detail will be included on final plans. 7.Provide calculations to confirm the adequacy of the sizing for the proposed culverts. The culvert shown on sheet C02 velocity exceeds 6 fps. Design outlets to the wetlands to achieve an outlet velocity less than 6 fps. The proposed culverts, including the noted culvert on sheet C02, have been modified to reduce velocity to less than 6 fps for the 100-year storm flow. HydroCAD results for proposed culverts are provided in the following table: Sheet #Culvert LocationPeak Flow Velocity C01Outlet from Basin B1P5.8 FPS C02Under Lot 2 Driveway4.4 FPS C02Outlet from Basin B2P4.6 FPS C03Outlet from Basin B5P5.9 FPS C04Outlet from Basin B8P3.9 FPS 8.Address all redline comments shown on plans 9.Grading or construction in the utility easement will require the authorization of the facility owner a.Verify all clearances are met and poles are not undermined with construction b.Show all utilities and poles on plans 10.Label all EOFs 11.Show all proposed wetland buffer signs on plans (see preliminary plat) 12.One of the 918 Contour lines that extends across several pages is the wrong line type 13.Adjust Lot 4 Plan Sheet to include the full extents of Lot 4 14.Show how water in the low area along the roadside of Lot 4 gets to the wetland to the west a.Provide a proposed culvert with invert elevations Lake Amelia Woods Final Plat Engineering Review
