Comments 1 —May 30, 2018
Comments 2 — August 2, 2018
The scope of the project and plan sheet numbering has changed. The previous plan review
comments that remain in effect have been rearranged to correlate with the new plan sheets.
GENERAL
1. August 2, 2018 — Response letter states that no work is planned for 219th; however,
frontage improvement work along 219th St SW will be required with the removal of the
parking garage entrance. Please revise plans accordingly.
May 30, 2018 comment - The site development plans/civil construction plans for this project
should show all proposed improvements on private property, as well as existing and proposed
changes to frontage improvements along 219th St SW.
2. August 2, 2018 — Response letter states that no closures of 219' are anticipated; however,
frontage improvement work along 219' St SW will be required with the removal of the
parking garage entrance. Please provide a traffic control plan.
May 30, 2018 comment - Provide a traffic control plan addressing lane closure on 2191h during
construction.
August 2, 2018 — comment not addressed. It has been stated that some coordination with
the applicant's traffic engineer is needed; however, no questions have been posed by the
traffic engineer so it is unknown what is needed.
May 30, 2018 comment - Provide traffic impact analysis worksheet. Refer to City Handout
E82.
C-01— TESC PLAN AND SEDIMENT CONTROL
1. August 2, 2018 — Comment partially addressed. It is understood that the current project
does not trigger stormwater management, but the proposed improvements will direct
stormwater runoff to the existing system and therefore the requested information is
applicable to this project. An Impervious Surface Area Analysis chart was provided that
still includes a net change. Please refer to the net change discussion below and revise the
table accordingly. In addition, provide a response to (a.) below.
May 30, 2018 comment - Include Hard Surface Area chart on the plans. Provide a
breakdown of all existing and proposed impervious/hard surface areas.
a. Indicate the quantity of impervious surface area that currently drains to the existing
stormwater management system and how much area will drain to that system in the final
condition.
b. If the current project creates or replaces more than 2000sf of impervious/hard surface
area and the proposed amount exceeds the capacity of the existing stormwater
management system, then a new/additional stormwater management system will need to
be provided.
c. A chart has been provided on Sheet TI-0.0 that includes a net change. The net change
does not determine stormwater management requirement thresholds, the project itself is
what this determination is based off. If the project itself creates 2000sf or more hard
surface area then stormwater management will be required. The question is how much
of that can/will drain to the existing on -site stormwater management system and how
much of that will need to discharge to a new on -site stormwater management system.
2. August 2, 2018 — Several labels on the plans have been left incomplete such as "Existing
tree to ... ". Please revise as needed.
3. August 2, 2018 — revise note that states "line of erosion control fencing / hay bales" to state
straw wattles instead of hay bales.
4. August 2, 2018 - Please clarify what the blue striped hatching indicates on the plans.
5. August 2, 2018 — See comment 1 under C-02 below. Revise demo plan as needed to
address future conditions.
C-02 — SITE WORK — CIVIL / LANDSCAPE
1. August 2, 2018 - Remove features from this plan sheet that are shown to be removed on
the demo plan. This plan shall clearly show what is to be constructed.
2. August 2, 2018 — As noted in the comments above, with the removal of the entrance to the
parking garage, the driveway approach shall be removed. The approach will also not be
used by the trash hauler as the plans currently indicate. A wide curb ramp may be
provided to roll the trash bin in and out of the enclosure, but this will not look like a
driveway approach. A driveway approach is intended to lead vehicles onto a site, typically
to a parking area. Revise plans to show new curb, gutter and sidewalk per City standards.
Standard details pertaining to frontage improvements shall be included in the plan set.

May 30, 2018 comment - Closure of existing parking garage will require existing driveway
approach to be removed and replaced with standard curb, gutter and sidewalk. Revise plans to
show proposed improvements and reference City standard details.
3. August 2, 2018 — Areas that are converted from impervious to landscape area shall be
compost amended. This may apply to some of the area where the old driveway will be
removed.
May 30, 2018 comment - Add note: "disturbed areas to be compost amended".
4. August 2, 2018 — Response comment letter states these will be confirmed on site by the
contractor prior to beginning work. As the project consists of underground utility work,
knowing the location of these existing utilities is critical. Please revise plans as requested.
May 30, 2018 comment - Show location of existing water, sewer, storm and dry utilities on the
site.
6. August 2, 2018 — comment not addressed.
May 30, 2018 comment - Show location of existing stormwater management system and show
conveyance lines to that system.
7. August 2, 2018 — comment partially addressed. RIM and invert elevations at existing and
proposed structures has not been provided. Please note, in reconfiguring the driveway
approach and access to the trash enclosure, a drain may not be necessary. Some of the
area currently shown to be concrete may become landscaping.
May 30, 2018 comment - Note TI 5 on sheet TI-0.0 states the existing storm drain line will be
extended. Clearly indicate location of existing catch basins and conveyance lines and label as
such. Provide RIM and invert elevations at existing and proposed structures and indicate how
existing lines (if any) will be connected to the storm system in its revised location.
8. August 2, 2018 — The new mailbox location has been shown on the plans; however, it is not
accessible from a mail delivery vehicle on 2191" St SW. Please coordinate with the post
office on an approved location with access from 219' St SW.
May 30, 2018 comment - TI 10 — Note states "Move mailbox (approx. 6') to location shown".
Please revise plans to also show location of existing mailbox.
9. August 2, 2018 — For clarification, landscape bark would be considered a pervious surface,
but typically a play area would have wood chips or other surface instead of bark. The
surface material was questioned to confirm impervious/pervious area quantities, but also
to confirm whether an open grate on the CB would be acceptable. The existing CB falls
within a play area in which children will be running and playing. There is high
probability that the material will fall into or be dropped into the catch basin. This needs
to be reviewed closely to prevent issues within the storm system that would affect the
overall function of the system.
May 30, 2018 comment - TI 4 — Note states "... assume landscape bark" As this area will be the
kids outdoor play area, it is assumed that landscape bark will not be used. Please clarify what
surface material will be used at this location — will it be pervious or impervious?
10. August 2, 2018 — Please provide topography contour elevations.
11. August 2, 2018 — Refer to plan review comments from Steve Fisher regarding the trash
enclosure. Revise plans to show the required concrete pad for the enclosure.
