Plans.
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 Worksheetto complete the estimate.
A bond is required to be placed for all right-of-way improvements. The amount of the bond will
o
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 fromPermit Coordinators Linda Thornquist or Kristin Johns at 425-771-0220 or by email
at linda.thornquist@edmondswa.govor Kristin.johns@edmondswa.gov
Inspection fees for this project will be calculated at 3.3% of the 120% City approved estimate for
o
all improvements.
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.
3.Show all dry utilities, including vaults, and required utility separation.Please add a note that a
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.
4.Provide a Construction Sequence similar to that found on the City website or through this link.
5.Truncated domes will not be required along property frontage. Please revise plan sheets accordingly.

STORMWATER REPORT
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.shuster@edmondswa.govwith 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.
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 minamum requirement #8 (Wetland Protection). Please include.
3.Section 5, A & B – Indicate that based on the geotechnical study, the site will be modeled in WWHM using
Type C soils.
4.Section 5, C & E – The site is located within the Halls Creek drainage basin, making part of the Greater
Lake Ballinger Watershed (Edmonds Stormwater 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 Stormwater Management Manual for Western Washington or the phosphorus
treatment technologies approved by Ecology with a General Use Level designation
(http://www.ecy.wa.gov/programs/wq/stormwater/newtech/technologies.html). The most common of
these technologies used in Edmonds are the Kristar Flogard Perk 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 stormfilters that are included in the current design.
5.Section 5E – Include the WWHM reports for sizing the water quality treatment system.
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).
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.
Plan Sheets
8.Sheet C3.1 - CBs 6 and 8 (water quality treatment) should reference details on the configuration of the
treatment system (usually the manufacturer’s detail for the specified products(s))
9.Sheet C3.2, Detail 3 – The City has changed its standard for a flow control structure eliminating the shear
gates. See standard detail 5.4
(http://www.edmondswa.gov/images/COE/Services/Permits_and_Development/Standard_Details/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.
STORMWATER VAULT –STRUCTURAL PEER REVIEW
1.Peer Review of the structural design for the detention vault was competedby David Evans and
Associates. Comments from DEA were provided to CG Engineering on June 19, 2014.Please
address comments accordingly.

SHEET C2.1–TEMPORARY EROSION CONTROL PLAN
1.A sediment trap can be constructed with an overflow piped to the storm system; however, the plans
show an overflow spillway that will overflow across the public sidewalk. Please revise plans
accordingly.
2.Please revise the leader for the filter fabric fence so it points to the correct line. It currently points to
the property line.
3.Add notes that the existing sidewalk is to be removed and replacedand reference Sheet C5.1.
4.Add notes that the existing curb and gutter shall be removed and replaced in areas of replaced
driveway approaches and as determined by the Engineering inspector.
5.This project is in a high pedestrian location. Please addnotes that existing sidewalk shall be
maintained until removal and immediate replacement is planned. Temporary patches for utility
cuts/connections should be with asphalt.
6.Add notes in the location of the proposed construction entrance that the existing asphalt driveway
approach (and any on site asphalt) shall bemaintained as long as possible during construction.
7.Where existing water meter is to be removed and service abandoned, add a notethat the service shall
be cut and capped at the water main.
8.Show existing fire line from water main to the DCVA. The fire line will also need to be cut and
capped at the water main.
9.Show location of existing sanitary sewer line. Is there any intent to use the existing sewer 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
Page 3of 5
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 main line. Please add notes to the plans accordingly.
10.The trash enclosure area is not shown consistent on this plan sheet. Please revise.
SHEET C2.2–EROSION CONTROL DETAILS
1.The rock check dam detail provides Sections A-A and B-B. Please indicate where these cross sections
are taken from.
SHEET C3.1 –PRELIMINARY GRADING AND DRAINAGE PLAN
1.Please remove the word “preliminary” from the sheet title.

new gas service rerouted around the sewersystementirely.
2.Domestic water meter shall be shown in the ROW at the property line.
3.The tap off the domestic service for irrigation shall occur on private property. Please revise plans
accordingly.
4.Please clarify what is meant by “future phases” in the note that states “2” domestic service w/ 2”
meter (to be sized in future phases) per ….)
5.Show existing domestic and fire line connections at the main that are to be abandoned. The trench
shall be expanded to include this work.
6.A 6” inline valve shall be shown on the fire line near the City main connection.
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.
thth
8.The plans currently show two existing inline valves in 76Ave W near 210Street 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 withthe 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.
9.In addition, when a building is setback from the ROW by more than 10-feet a vault for the fireline
DCDVA is typically required. Staff is also discussing this issue and will follow-up with you.

are taken from.
SHEET C5.1 –STREETIMPROVEMENT PLAN AND DETAILS
th
1.Please submit a traffic control plan for all phases of work in 76Ave W. TCP will need to reflect the
actual number of travel lanes and state specific working hours so as not to conflict with peak school
traffic in the area. Please also provide a haul route plan for review and approval.
2.To provide clarity in how construction activities will disrupt traffic, please show travel lanes and
painted center line.
3.Clearly identify paving restoration limits. At a minimum the water and sewer utility patching shall be
incorporated into one solid patch. The storm system will likely need to be incorporated into this patch
as well. As currently shown, the storm trench would require a half-width or more overlay.
4.Replace standard detail E2.10 –Vertical Curb with E2.8 –Curb and gutter.
5.Truncated domes are not required at drivewayentrances. Please remove from plans.
