Comments 1- June 23, 2016
Comments 2 — September 6, 2017
GENERAL
1. September 6, 2017 — Thank you for providing an engineer's cost estimate. Please revise as
follows:
a. Include traffic control for work performed within the City right-of-way
b. Revise sidewalk lineal footage to include curb ramps at the driveway
c. Include striping for stop bar and arrows
d. Include trash enclosure
e. Include parking stall striping within the building
f. Include oil/water separator
g. Update cost estimate as needed based on the following plan review comments.
6/23/2016 - Provide an itemized engineers cost estimate for both on -site and off -site (right-of-
way) improvements, including traffic control and all utility installations. Use the King County
Bond Quantity Worksheet (available on the county website) and utilize "write-in" sections
where appropriate. The amount of the bond will be based on 120% of the City approved
estimate for the off -site improvements.
h. A 3.3% inspection fee is calculated for the project based on 120% of the City approved
estimate for the entire project improvements.

3. ok
4. September 6, 2017 — Response letter states this will be provided by the contractor. Please
note, the traffic control plan will need to be submitted to the City prior to permit issuance.
6/23/2016 comment - Provide a Traffic control plan for review and approval.
5. September 6, 2017 — On 8/6/2017 an email was sent regarding the need to update the
traffic impact analysis to be consistent with the current project proposal. An incorrect
number of apartments, retail square footage and fee rates have been used. To date, I have
not seen a revised analysis. Please submit for review and approval.
6. September 6, 2017 — Thank you for updating the plans with the last submittal to show the
public pedestrian easement area required for that portion of the sidewalk that falls within
private property. As the easement is to be approved by City Council, please provide a
reduced size plan sheet (8 V2 x 11 if possible) that specifically details the easement area.
• The easement will be taken to Council Committee as the first step (and prior to permit
issuance). The next Council Committee meeting is September 26'.
• Final approval before City Council will need to occur prior to project completion and
at a point when the sidewalk has been constructed to confirm exact location.
Please have the requested documentation to me no later than September 191h, in order to
make the 9/26 council committee date. This document can be emailed directly to me —

Sheet D-1.0 — DEMOLITION AND ESC PLAN
1. Revise Demolition Key Notes as follows:
G: September 6, 2017 — Sheet D-1.0 was updated to reflect relocation of the sign, but
references C-1.0 for new location. In reviewing C-1.0 the new location was not found.
Please clarify
6/23/2016 comment - The truck route sign on Edmonds way shall be removed when needed
during construction and preserved so that it can be re -installed prior to project final. Please
revise note or add a new note to reflect this. Also there is a private business sign on private
property near Edmonds Way on the old single-family parcel that is to be removed. Please
update plans to reflect this.
H: September 6, 2017 — Response letter states the re -use of existing DDCVA will be
evaluated by OVWSD during their review/approval process. In reviewing the Utility Plan
Sheet C-3, it is unclear that the DDCVA is being proposed for relocation. To resolve any
Page 2 of 6
potential conflict with OVWSD approvals, please add an approval block to the demolition
plan for OVWSD, in addition to the Edmonds approval block. T
6/23/2016 comment - Confirm with OVWSD that this is acceptable.

etc. will be restriped prior to project completion.

1. September 6, 2017 - Response comment states the existing 8" sewer line is located on
adjacent private property not controlled by this project and therefore a connection is
shown to the main in Edmonds Way. However, the 8" line is a City main line and the City
Page 3 of 6
has an easement across the adjacent parcel: AFN 1858336. Please revise the plans to show
connection to this existing 8" main line and not in Edmonds Way.
6/23/2016 comment - A sewer manhole shall be installed with an 8" connection to a City sewer
main. The sewer main located in Edmonds Way is a 24" line and the sewer main along the west
nection to the 8" main line.
2. September 6, 2017 — Thank you for adding the callout. One of the references to Key Note
P is not pointing to the sewer entry. Please revise.
6/23/2016 comment - Callout sewer pipe size for lines exiting the building.

7. September 6, 2017 — Response letter states the pre -application meeting documentation and
City GIS information indicated the sewer will be provided by OVWSD. However, upon
further review of the project, it has been realized that the original parcel 10032 Edmonds
Way is actually a City of Edmonds customer. Furthermore, connection to the 8" line to
the northwest of the property creates the least amount of impact to traffic and street
disruption and is the preferred approach. Please revise plans accordingly.
6/23/2016 comment - The water system shall be approved by the Olympic View Water and
Sewer District. Consider two different plan sheets (a sewer/general utility plan and a separate
water plan) or include approval blocks for both Edmonds and Olympic View on the same plan
sheet.

STORMWATER REPORT
The following comments are provided from Robert Edwards, Stormwater Engineer. Please
contact Robert directly at 425-771-0220 or by email at Robert.edwards(aedmondswa.2ov with
any specific questions you may have regarding these comments.
September 5, 2017 Comments:
Background
This is classified as a Large Project because it involves 1 or more acres of land disturbing activity.
Large Project are subject to Small Site Minimum Requirements 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11.
Minimum Requirement #1— Preparation of Stormwater Site Plan
Comments:
1. Storm Drainage Report, Page 108: WWHM modeling is to use the Puget East rain gage, not
the Everett rain gage. This is accessible by selecting the WS-DOT data on the project screen.
This comment remains unaddressed. The engineer's response "no guidance to use another
rain gage is identified in City code or stormwater addendums" is incorrect. The use of the
Puget East rain gage has been in effect at the City of Edmonds for 7-years. This is cited in
the 2010 Stormwater supplement on page 18, table 4-4, or more recently in the 2017
Addendum, page 5, Section 2-6. Please provide updated hydrologic/hydraulic modeling
analyses compliant with this requirement.
2. Storm Drainage Report Pages 119 and 123: Several of the selected BMPs rely on
infiltration. The geotechnical report did not perform an infiltration evaluation. An infiltration
evaluation needs to be performed and infiltration rate(s) need to be determined for final
design of these BMPs. This comment remains unaddressed. As this submittal is for permit
and construction, final design must be prepared. Please provide infiltration testing for this
final design.
3. Geotechnical Report, Page 9: Infiltration investigation was not performed. This comment
remains unaddressed. As this submittal is for permit and construction, final design must be
prepared. Please provide infiltration testing for this final design.
Page 5 of 6
4. Sheet CV-1.0, General Notes, 435, specify which compaction test is required. (e.g.,
modified proctor, ASTM D1557) This comment remains unaddressed. The design engineer,
being the engineer of record, must specify the proposed compaction testing.
5. Sheet C-2.0, Structure IA: The plans propose a "Type 2 CB (54")*" The proposed CB ties
into an existing 36-inch diameter concrete pipe. The maximum pipe allowance for a 54-inch
CB is 30-inch concrete pipe. For help in designing Type 2 CBs, see WSDOT Standard Plan
B-10.20-01. Please clarify the use of an asterisk in this context.
6. All plan sheets and report are either unstamped, unsigned, or marked "Preliminary Not For
Construction" The submittal is for permit and construction and is considered to be a final
design. As such, all plans and reports must be stamped and signed per WAC 196-23-20.
Please provide stamped and signed plans and reports.
7. Response letter dated July 14, 2017: The letter is addressed to the City of Renton at the City
of Renton's address. This project is in the City of Edmonds. Our address is 121 5th Avenue
North, Edmonds WA 98020.
