This letter addresses comments from you and other city staff members which were provided in an email dated July 25th, 2017. Sewer/Drainage(Arnie Roshak) 1. Due to the layout of the developed site, splash blocks would not be beneficial in this case. There is little vegetation that will remain on-site after final construction and a vegetated sheet flow path would not be met. 2. The proposed stormwater system within the right-of-way of McDougall has been rerouted to direct runoff north toward the intersection of McDougall and 33rd. The system will tightline to the existing stormline near this intersection, per discussions with City staff. See revised sheets 3 and 4. 3. Catch basins 4 and 6 are now proposed to be installed per COE standard drawing 401. See revised sheet 4. 4. A floatable material separator has been added to the last structure in the proposed on-site drainage system, which connects to an existing stormline on-site before discharging to the combined sewer within the right-of-way. See revised sheet 3. 5. The drain line was also field verified and is located on the project site. Water Review 1. The utilities sheet has been updated per the redlines on the plan. The correct water line is shown and the new fire line is now shown connecting to this line (8"). See revised sheet 3. Planner 1. The sidewalk has been updated to show 8' in width. 2. The landscaping note has been added to the plans. Please see sheet 1. 2
