Dear Ms. McConnell:
The following is in response to your correction checklist dated July 16, 2014 (revised).
Please find listed below our itemized responses:
GENERAL
1. Please provide an itemized engineers cost estimate, including units and unit prices, for both on-
site and off-site (right-of-way) improvements, including traffic control. Please utilize the King
County Site Improvement Bond Quantity Worksheet to complete the estimate.
o A bond is required to be placed for all right-of-way improvements. The amount of the bond
will be based on 120% of the City approved estimate for all right-of-way improvements. The
City will inform you of the appropriate bond amount after review of the cost estimate. Bond
forms can be obtained from Permit Coordinators Linda Thornquist or Kristin Johns at 425-
771-0220 or by email at linida.thornquist@edmondswa.gov or
1,,'-i-istin.j'ohns@edmondswa.gov
o Inspection fees for this project will be calculated at 3.3% of the 120% City approved estimate
for all improvements.
RESPONSE: Please see attached an itemized e)7-i17eers cost estimate, includirng units and tmit
prices, for both on-site (right -of �vay) improvements, including traffic control. The King County
Site Improvement Bond Quantity Worksheet has been used to complete the, estimate.
2. Please include a City of Edmonds Engineering approval block on each plan sheet. A sample
approval block can be found on the City website or through this link.

minimum of 3' separation is required between the dry utilities (power, gas, phone, cable, etc.)
and sewer, water, and storm and 5' from any City main lines.
RESPONSE: Layers added to civil plans. Note added to C3.1 plan sheet.
4. Provide a Construction Sequence similar to that found on the City website or through this link.
RESPONSE: Added to C 1.1 Sheet

RE SPONSE: Added to plans.
The following comments are from Jerry Shuster, Stormwater Engineer, and were
emailed to CG Engineering on July 1, 2014. Please contact Jerry directly at 425-771-
0220 or by email at jerry.shustei-Ca),edmondsiva.gov with any specific questions you may
have regarding these comments.
1. Section 1, second from the last paragraph — Include that this site qualifies as a Large Site
Project per ECDC Chapter 18.30.
RESPONSE: Added to report where indicated.
2. Section 3 — This section properly lists the minimum requirements applicable to the project.
The reviewer could not find discussions on how the project complies with minimum
requirement #3 (Source Control of Polltion) and minimum, requirement #8 (Wetland
Protection). Please include. I
RESPONSE: The site does not discharge directly or indirectly into a wetland., so i-niniMMI-1
requirement #8 does not appear to be applicable. This is discussed in Chapter 4 of the report,
Source Control is discussed in Chapter 6.
3. Section 5, A & B — Indicate that based on the geotechnical study, the site will be modeled in
WWHM using Type C soils.
RESPONSE: Added to noted parts of report.

4. Section 5, C & E — The site is located within the Halls Creels drainage basin, making part of
the Greater Lake Ballinger Watershed (Edmonds StormlVater Code Supplement [ESCS] page
51). Consequently per ESCS Section 5.6.2.2, phosphorus treatment of the runoff from the
pollution generating impervious surface is required. The designer can choose from those
treatment technologies in the 2005 or 2012 Ecology Storinwater Management Manual for
Western Rashington or the phosphorus treatment technologies approved by Ecology with a
General Use Level designation
(http://www.ecy.wa.yov/programs/wq/stormwater/newtech/teclu-iolovies.html). The most
common of these technologies used in Edmonds are the Mistar Flogard Perls Filter (low head
requirement) and the Americast Filterra units (Note: the City is not endorsing the use of these
products, just providing some potential options that will meet the regulatory requirements.).
The same "pretreatment" requirements apply to these'technologies that apply to the Contech
stormfrlters that are included in the current design.
RESPONSE: Perls Filters by Kristar have been implemented into the design in }dace of the
Storrmilters.
Section 5E — Include the WWHM reports for sizing the water quality treatment system.
RESPONSE: Added to report.
6. Section 5F— Show that the riser. pipe that is part of the detention system control structure can
handle the 100 year un -detained flow (1.16 cfs).
A SPONSE: Discussion of the overflow capacity added to this section.
7. Section 6 — Since the site is classifies as a Large Site project, it is subject to the requirements
in Appendix I of the City's stormwater discharge permit with Ecology. While most of the
requirements have been addressed, the City requires the applicant fill out the Permit
Appendix 7 (Construction Site Sediment Damage Potential Worksheet, enclosed). This form
helps the City's inspectors plan for the frequency of inspection during construction. Please
include a filled out worksheet in the report.
RESPONSE: This worksheet is added to Section 6. It does not appear that any of the -erosion
sensitive features denoted in Step 1 are applicable. If none of these features apply, Step 1.
indicates the assessment to be complete.
Plan Sheets
8. Sheet C3.1 CBs 6 and S (water quality treatment) should reference details on the
configuration of the treatment system (usually the manufacturer's detail for the specified
.products(s))
RESPONSE: Details added (Sheet C3.3)

tails/Storm Drainage/E5-4 FLOW CONTROL STRUCTURE.pdf ). An AutoCad version
is available upon request. Note that either a v -notch or a rectangular notch is permitted.
RESPONSE: Added to C3.3. Detail 3/C3.2 has been left in the plan set to convey design
information for this specific project, although we. have removed the shear gate and updated
dimensions accordingly.
STORMWATER VAULT — STRUCTURAL PEER REVIEW

Associates. Comments from, DEA were provided to CG Engineering on June 19, 2014. Please
address comments accordingly.
RESPONSE: Comments addressed in separate response letter.
AM — SITE PLAN
1. Please revise the site plan so as not to include specific notes related to civil construction plan
improvements. A note should be added to the Site Plan that states "Refer to Civil Construction
Plans for site development requirements."
RESPONSE: A note has been added on site plan sheet A 1.1 that states "Refer to Civil.
Construction Plans for site development requirements.

lateral? If so, the condition of the lateral will need to be TV'd by the City Public Works
Department to determine its condition and if it's acceptable to reuse. If it not acceptable to reuse
or if the intent with the proposed design is to run a new lateral, then the existing lateral shall
either be cut and capped,at the property line or chased back to the mainline. Please add notes to
the plans accordingly.
RESPONSE: Location of existing seNver shown (as much as is known). We are not Planning. to
reuse this line.
10. The trash enclosure area is not shown consistent on this plan sheet. Please revise.

trench shall be expanded to include this work.
RESPONSE: Trench expanded, lines shown, note added.
6. A 6" inline valve shall be shown on the fire line near the City main connection.
RESPONSE: Crate Valve added.
7. Please move the fire line connection closure to the domestic service connection. Moving this
line further to the south would also eliminate the need for a bend at the building..
SPONSE: Fire line had to be moved farther apart due to added vaults, utility separations. etc.
8. The plans currently show two existing inline valves in 76th Ave W near 210t" Street SW. These
valves do not exist as inline valves. Please remove from plans.
The City's PW Operations group has indicated a very large area would be affected by a
water main shutdown. Instead of installing a valve cluster with the fire line connection to
the City main, an EZ -valve. 2 inline valve insertion may be required. Staff is currently
discussing this and will follow-up with you soon.
SPONSE: EZ -2 valve added as directed.
