If all the corrections are made, mylars will be requested. The remaining items in the general comments shall be addressed prior to utility permit issuance. The preconstruction items need to be completed prior to the preconstruction meeting. Please contact me if you have any questions. GENERAL COMMENTS Final plans need to be signed by the engineer or surveyor of record. *This is a typical comment for all sheets. The NPDES Permit number is WAR304395. Add this to Sheet GR-01. On Sheet GR-01, update background storm drainage linework to show the new proposed storm drain alignment. Adjust the construction limits to accommodate for the new alignment. Revise the layout of the off-site bypass pipe shown on Sheet FR-01. Add a type 2 catch basin east of CB #22 where the continuation of the storm drain alignment between CB #17 and CB #18 would intersect. No additional overlay is required provided the trench line is not closer than 3’ to the adjacent lane. Revise all plan callouts accordingly. Revise the profile and profile callouts to match the new pipe alignment. Show all utility crossings in the profile including water, sewer, and gas. Change CB #22 from a type 1 catch basin to a concrete inlet. Make this change on Sheet FR-01 and Sheet RD-03. On Sheet FR-01, add note to rotate sewer manhole riser so that lid is not in the curb line but instead is in the planter strip along 116th Avenue SE. The structural plans for the pond walls call for a footing drain. Show where the footing drain will drain to on Sheet PN-01. On Sheet PN-03, update the restrictor plate orifice to match the KCRTS model. Update the pavement section on Sheet DT-01 to conform to the City’s standard pavement section per RMC 4-6-060.

Text is missing on the conveyance calculations sheet. Please ensure all text is showing in the final TIR. Update conveyance calculations so that they match the plans. Account for the new by-pass storm drain layout. CB #13 is now a perk filter vault. The in and out elevations have changed. Update the conveyance calculations in and out of this structure to match the plans. CB #10 and CB #11 values changed when the catch basin inverts were updated last submittal. No conveyance or backwater calculation is shown for the stretch of pipe from CB #18 to CB #17. Update bond quantity worksheets to reflect changes in materials. Include new storm drain, concrete inlet, and type 2 catch basin. Please have approved water and sewer plans from Soos Creek Water and Sewer District routed to the City for final review prior to permit issuance.
