12/1/09 - Please add a note to the plans that indicates all temporary asphalt walkway, curb and
gutter is to be removed and replaced with concrete walk, curb and gutter. It appears as though
the restoration boundaries might fall just short of encompassing the entire asphalt area.

1/14/10 Consistent with our discussions on 1/13/10, please revise plans to show sidewalk
1.
curb ramps that are necessary to transition the full height sidewalk to be flush with the
stained concrete driveway approach. Please see attached plan markup of what this could
look like.
12/1/09 - While it is not clear from this plan sheet if the stained concrete area is flush with the
driveable surface, it appears from Sheet 32-EDM-PS3 that it is.
a.A break in the curb is noted on the west side of the stained concrete, but curb ramps have
been provided to indicate a grade change from sidewalk to driveable surface. Please
revise accordingly.
b.It appears as though the curbing should wrap around the sidewalk areas. Please revise
accordingly.

12/1/09 - Please add a note to the plans that indicates all temporary asphalt walkway, curb and
gutter is to be removed and replaced with concrete walk, curb and gutter. It is difficult to tell if
the restoration boundaries encompass the entire asphalt area.
1/14/10 A few light pole locations are now in too close of proximity to the water main. In
4.
addition, light poles should not be located within the easement area. Please relocate
accordingly.
12/1/09 - Several light pole locations appear to be proposed over the top of existing utilities.
Please revise plans accordingly.

1/14/10 Thank you for relocating the water main and identifying the easement area. It
5.
appears as though a few of the parking lot light posts are now located within the easement
area and the concrete bases are too close to the water main. Please refer to Sheet 19
comment #4 above.
12/1/09 - Please adjust the location of the water and storm mains as follows on Sheets 24, & 25:
a.The City would like a 15 easement for the water main. While the easement will not be
provided until after the main install, consistent with plan note #5, the storm line will
need to be located outside the easement area. Show the location of the future water main
easement on the plans and adjust water and storm locations as needed so the only utility
within the easement area is the water main.
b.Move water main to west of current proposed location to eliminate/avoid bends in the
line.
c.Move the storm main east as needed to provide separation from water main and reduce
the need for bends in the water main.
6.The plans indicate the water service line will be 1 ½ diameter, while construction note 4 states
the size of the service is 1. Is note 4 really a reference to the water meter? Please revise
accordingly and ensure water meter size is called out on the plans.

b.Will the utility be placed with this project or is it for future use?
Bld20080257 Sound Transit Edmonds Station Page 4 of 7
c.Please clarify the area shown to the west of the steel casing in Railroad Ave. Is this the
remaining trench section for the utility or is this a bore pit?
d.Where will equipment be staged for this work?
2.Add in-line valves to either both sides of the hydrant connection to the main line.

located in the middle of the parking lot. As these signs will not be visible to vehicles, you
might consider painting the curb yellow instead.

1/14/10 Thank you for adding the pavement striping, however, the striping is difficult to

see. Please add a note that further brings attention to this striping.
Bld20080257 Sound Transit Edmonds Station Page 5 of 7
12/1/09 - Add pavement striping (just South of station) to better direct one-way traffic in both
the NB and SB directions. Striping should allow one-way traffic to continue around the parking
island as well as direct the two-way traffic heading south into the one-way lane.

stalls shown north of the Amtrak building to the curb ramp. Please revise.
1/14/10 Add 20 of center line delineating northbound and southbound lanes on the

south side of the James Street traffic circle.
1/14/10 - Add striping at James Street intersection approach (for northbound traffic and

westbound traffic) indicating that vehicles shall yield. Striping of isosceles triangles shall
be as shown on page 3B 25 & 26 of 2003 MUTCD.

1/14/10 Thank you for adding the stop sign. It appears as though a Right Turn Only

sign is identified on this stop sign and the stop sign at the exit from Railroad onto Main
Street. The MUTCD does not allow for placement of additional signs on the same post as
a stop sign. Please revise accordingly.
12/1/09 - Add Stop Sign to access Railroad Street heading west out of Skipper's parking lot.

1/14/10 No parking along Railroad Street should just be indicated by yellow curb
6.
signage is redundant in this case. Please remove signage.
1/14/10 Please relocate the Do Not Enter sign, shown on the west side of Railroad Street
7.
near Main Street, so it is closer to the Main Street intersection. This sign will need to be
visible to traffic heading east on Main Street. Placing the sign in the concrete is acceptable
with a use of a unistrut post and sleeve.
