The comments provided below are based upon review of the application and documents
submitted for the subject application. Additional information is requested from the applicant at
this time. Please ask the applicant to respond to the following.
Stormwater Engineer Review:
Refer to attached plan review comments by City Stormwater Engineer, Zachary Richardson.
Please contact Zack directly at 425-771-0220 or by email at
Zachary.richardsongedmondswa.gov with any specific questions you may have regarding his
comments.
1. See attached redlined plan.
General Engineering Review:
The plans are very difficult to read. Please consider that they are probably more difficult to
read on the printed sheets than in CAD. Please make revisions to clarify plans.
a. Please lighten up the existing conditions or just turn the layer off on all but the
existing conditions/demolition sheet.
b. Minimize call outs on items already identifiable by hatching etc, and use "typ".
call -outs to minimize clutter.
c. Show drainage in dark pen only on drainage sheet.
2. Frontage Improvements and Access:
a) Some areas of the plans are showing a 10 ft landscape strip and a 5 ft sidewalk. The
sidewalk appears to be 4 ft in width near the 72" d access. The CG code specifies that the
pedestrian zone be a 5 ft landscape strip, 5 — 10 ft wide sidewalks (dependent on row
availability) and an 18" amenity zone. Please revise plans to meet these specifications.
b) Street trees are required along 212' and 72nd. Please use a small symbol (not an actual
tree symbol) to show the planting locations to verify no conflicts with utilities. They
should be 40 on center on 2121h and 20 on center on 72nd St SW.
c) The sidewalk ramps at both driveway will be at least 6 ft in length, maybe longer on the
north side of the west exit on 72nd to meet the under 8.3% ADA slope requirement, please
revise plans.
d) Please identify the slope of the entrance on 212th, include the cross slope of the sidewalk
(verify it is under 2%).
e) The trash area and adjacent sidewalk area is not clear. Please provide a cleaner
presentation of that area. Will the area be accessed from the garage by garbage trucks?
accessed from the sidewalk?? Is that a curb cut for garbage trucks? Is there cover over
it all? Walls? Is it enclosed? There appears to be a storm pipe? Maybe a detail of the
area without the utilities would be helpful?

typical but do not control over other requirements of this chapter.
