RE: NYLAND APARTMENTS (formally Edmonds Apartments)
- RESPONSE TO CORRECTION NOTICE (PERMIT# BLD20170899/0900)
Dear Development Services,
Thank you for your review of the Nyland Apartments project (formally Edmonds Apartments). The
following is a response to the review comments from the Planning, Building, Engineering and Fire
Departments. The review comments are listed below along with our responses in bold. Our proposed
site, civil and landscape plans and supporting documents have been resubmitted back to the City of
Edmonds for our second review.
REVIEW COMMENTS BY JOANNE ZULAUF ENGINEERING TECHNICIAN, 9/21/17
GENERAL
1. 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
engineers cost estimate will be provided prior to plan approval.
a. The amount of the bond will be based on 120% of the City approved estimate for the off -site
improvements. Understood.
b. A 3.3% inspection fee is calculated for the project based on 120% of the City approved estimate
for the entire project improvements. Understood.
2. Please add a note to plans stating "A separate right-of-way construction permit is required for
all work within the city right-of-way." Please note, a ROW permit application with contractor's signature
shall be provided to the city prior to issuance of civil construction plans. Note added on Sheet C0.1.
3. Please provide a written response from the geotech that the civil plans are consistent with the
geotech report. Geotechnical review letter provided with our resubmittal.
4. Please consider moving the paving sheets (currently C1.1 and C1.2) to the end of the
construction sheets to mimic the flow of a construction job. Please move the general notes to the first
or second sheet. We are using a conventional sheet sequence for which I've used my entire career. I
my experience, the developers and contractors like to see the site / paving plan as the Csheets for general orienting of the site and understanding of the finished project.1 8 }j opy

5. Please submit a traffic control plan for work on 244th. A Traffic Control Plan will be provided
prior to plan approval. We have added a water main extension on SW 244th Street. We'd like an
initial review by the City prior to providing a TCP.
Include a haul route on 1st or second sheet. Provided on Sheet 0.2.
7. Some sheets are missing the City Engineering Division approval block. Please revise. This
approval block has been added to all civil sheets, except for the Olympic View Water & Wastewater
permit sheets.
8. Olympic View Water and Sewer District shall have their own approval block on pages specific to
their review and approval. The applicant will be required to submit plans approved and signed by
OVWSD prior to the final approval of the civil plans by the City. We are under review with OVWSD.
Sheets 1-5 are specific to the District reviewed water and sewer design and include their approval
block.
9. Stormwater Checklists (found in the Appendices of the Addendum) are required to be submitted
for all projects. Please complete and return Checklist #2, #3, #4, and #6 and any other checklists that
may apply to this project. The lists are a combination of informational material and plan requirements;
due to the formatting of the checklists, there is definitely some overlap within each checklist and across
the checklists. They are still a work in progress. Ultimately though they contain details that you may
have overlooked in our code and addendum or in the Manual so it is definitely to your advantage to
complete them. See attached completed checklists.
10. A Stormwater Covenant is required to be recorded against the property based on the proposed
stormwater facilities for the project. Please complete the covenant, including notarization and required
exhibits and submit to the city. The document must be complete, but will not be recorded prior to
permit issuance. Prior to construction final location of facilities are to be verified (by field inspection
and asbuilt) and then the covenant will be recorded. The Stormwater Covenant will be submitted prior
to plan approval.

carefully to understand all the prohibitions. The B62 Retaining Wall handout, located under the building
division handouts on our website, is available for wall construction information if needed to meet grade
conditions. Additionally, Per ECDC Chapter 18.70 approval of an Encroachment Permit may be granted
to locate a Retaining Wall within the City right-of-way if it does not interfere with the public's use of the
right-of-way and/or if the proposal benefits the public interest, safety or convenience. Ex. rockery is not
within the R/W.
41. Use the correct texture to show the access drive limits. Revised.
42. Add dimensions to the paved drive and the access easement. Added.
43. Please label all water lines as existing/proposed. Added.
44. Note that water meter lids shall be replaced with drive rated lids where necessary. Water
meters will be removed from the drive aisle; relocated to planters.

underground. Per follow-up discussion, the overhead wire can remain since the Denny's is served via
overhead wires from an onsite pole to their restaurant.
46. The existing 10' sewer easement limits are unclear. Linetype revised.
47. "Ex. A.C. Paving" is called out in the access easement. Please add note to the plans stating
existing failing, damaged or non-ADA compliant frontage improvements shall be removed and replaced
as determined by the City Engineering Inspector. Added.
48. City of Edmonds requires a 2 ft minimum sawcut, please revise note. The road will be restored
with an grind/overlay.
49. Add the COE standard details for paving and reference wherever paving will be performed in the

60. Add name and contact number for CESCL or preparer of the SWPPP or other tesc responsible
person on plan sheet with construction sequence. Note added but blank; contractor not chosen yet.
61. Construction is proposed to begin in wet weather season. Tesc proposed shall meet wet
weather tesc requirements. Specific wet weather requirements shall be prominently noted on plan and
noted in construction sequence. Schedule changed; clearing and earthwork proposed during Dry -
Season. Note added and SWPPP revised.
62. Show job shack location, if any. Added.
63. The location of the temporary sediment pond is in the same location as the proposed
stormwater system. Please revise plans to avoid this conflict. Moved to the bioretention planter area.
TESC pond can remain in place until the sitework is nearly complete and then the bioretention planter
can be installed on TESC pond removed.
64. A temporary sediment pond typically is designed to remove sediment no smaller that medium
silt (0.02mm). This method does not lower the turbidity enough for the runoff to leave the site. See
2014 SWMMWW BMP C241. Minimum turbidity of 25 NTUs is required for runoff directed off site. The
temp sediment pond may be used but will be subject to daily turbidity testing. Provide a point for
testing the NTUs after the pond and before the property line. The testing is to be provided by special
inspection. A special inspection form from the engineering division shall be completed with all required
signatures and submitted prior to plan issuance. Other options include removing the water from the
pond via baker tank or similar. Please clarify which option is to be followed by the contractor or revise
plan using another tesc measure. We are planning for Dry -Season clearing and grading. We expect
less issues of erosion and sediment control. Sediment pond sized for the 10-yr/24-hr storm event.
65. Show all existing trees on the plan. Indicate trees to be removed and show tree protection for all
trees to remain. Add standard detail for tree protection. Added.
66. The BMPs noted in the SWPPP to be installed shall be shown on the plans. Add note referencing
other measures (from SWPPP) to be installed "as needed". Added.
67. All tesc bmp standard details referenced are from the SWMMWW, Vol II chap 4, please replace
COE details with the SWMMWW details on sheet C6.1. Please use the stormwater manual detail
reference numbers so reference can be made to the stormwater manual extended summary of the bmp
if needed. Revised.
SWPPP REPORT
68. Section 2.2. Cut and Fill amounts are not consistent with Sheet. Revised.
69. Section 6.2.1 Please correct "If turbidity exceeds 250 NTU" to 25 NTU. Revised.
70. Appendix B Construction BMPs is missing page 2A-73, which includes part of the description of
the sediment pond. Please add page and check for other missing pages. Revised.
SHEET C3.1— GRADING AND DRAINAGE PLAN
71. The portion of segmental wall ranges from 2 ft to 6 ft. The "large" segmental wall ranges from 2
ft to 3 ft. Are they mislabeled as the smaller wall states it is being designed by others? The wall
standard detail 3/3.2 is consistent with the COE detail E8.12 Modular Block Wall. At heights over 4 ft,
they must be designed by an engineer. Also a 2 ft shy distance must be maintained between driveway
areas. See new Sheet C6.4 — Wall Details as provided by Associated Earth Sciences.

72. There is a symbol on the center landscape strip located on the north row of parking stalls. It
appears to have no label. If existing cb, please provide rim and invert elevations, if not, please label to
identify. —found it on the sewer plan -please label the new light standard. Labeled as a parking light.
73. Rolled asphalt berm or trench drain call out. Please choose one and depict on the plans. A
trench drain will require an invert elevation at the connection to tightline. Asphalt berm proposed,
storm trench option omitted.
74. Please label the Bioretention Swale as a Bioretention Planter. Also please correct reference
from 3/C4 to 2/C6.2. There is no sheet C4 in the drawing set. Revised.
75. The very first infeasibility criteria for bioretention-in the SWMMWW Vol V, page 7-9 is the
following:
"Where professional geotechnical evaluation recommends infiltration not be used due to reasonable
concerns about erosion, slope failure, or down gradient flooding."
Please review the Subsurface Exploration, Geologic Hazard, and Geotechnical Engineering Report
Section 4.3 on page 4. "infiltration into the till is not recommended."
Please choose another treatment consistent with those conditions or provide specific information in the
stormwater report stating that this system is the appropriate choice for the soil conditions. The
Bioretention Planter is designed for Runoff Treatment only with an underdrain to the downstream
detention system. No infiltration capacity was assumed when sizing this facility. The existing till soils
will provide very little infiltration and the use of the underdrain will keep any infiltration head to a
minimum.
76. The note located at northeast of site "See Sheet C4 for Offsite Storm Line" references sheet C4.
Sheet C3.2 is the location of that information. Revised.
77. Where the sewer enters the adjoining condominium property, please extend to show the point
where is crosses the proposed storm line. Provide approximant inverts for both pipes at point of
crossing. Revised.
78. Provide a copy of the easement agreement (draft okay) with the condominiums for stormwater
installation and access. Draft stormwater easement agreement with Sunrise at Edmonds
Condominiums provided within Appendix E of the revised Storm Drainage Report.
79. See Stormwater Engineer Comment Letter for additional comments on Sheet C3.1.
a. If a vault is chosen for stormwater mitigation, a separate structural plan and calculations shall be
provided. The vault submittal will be sent out for peer review. The fee is $300 plus the consultants peer
review fee which will be pass through. Underground Wiring Requirements of ECDC 18.05 shall be
followed. All utility services shall be installed underground. Design has been changed to an
underground detention tank system. 54-in diameter CMP proposed.
b. Show location of pad mounted transformer; it is to be located on private property. Added near
the NW corner of the site.
C. Show location of dry utilities and required utility separation (5-feet from City utilities within the
ROW and 3-feet from water/sewer/storm utilities on private property). Added.
SHEET C3.2 — GRADING AND DRAINAGE PLAN
80. Please provide the bottom and top elevation of the rockery on the condo property at the
location of the proposed storm line. If the rockery will be removed at that point and it meets any of the
prohibition criteria, please provide a proposal to replace. See comment #21 above under SHEET C2.1.
Added.

SHEET C4.3 — SEWER PLAN
81. The plans show an existing sewer easement. Is there a sewer line in it? Please provide a copy of
the easement language to confirm the installation of other improvements do not interfere. The
dumpster, for example. There is no existing sewer main along the east property line. We are working
on getting this easement relinquished by the District.
Sheet L1.1— LANDSCAPE PLAN
82. Add Note: "A separate irrigation permit must be obtained from the City Public Works
Department. Prior to final acceptance provide a copy of the backflow test report to the City's Cross -
Connection Control Specialist. Test reports can be faxed to 425.744.6057 or e-mailed to
jeff.koblyk@edmondswa.gov. Backflow testing will be required on an annual basis thereafter."
Understood.
83. Please review Civil Sheet C4.2. Please see the fire equipment placement and provide plantings
that will not interfere with access. Plantings have been omitted near the fire hydrant and FDC's
84. The bioretention planter is shown with 5 large bushes that spread up to 5' in width. Please
arrange and choose planting that will leave access to clean out and to beehive outlet free for
maintenance of the mitigation system. The proposed shrubs have been moved.
STORMWATER REPORT
85. Page 7. Please elaborate or revise the criteria used to move down the bmp lists. The
infeasibility criteria must be addressed consistent with the 2017 COE Stormwater Code and Addendum,
and the 2014 Stormwater Manual. The report has been revised to include the Infeasibility Criteria
provided within your Addendum.

Background
This is classified as a Category 2 Small Site because it proposes impervious area exceeding 5,000 SF.
Category 2 Small Site Projects are subject to Small Site Minimum Requirements 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
and 11.
Minimum Requirement 41 — Preparation of Stormwater Site Plan
Comments:
1. TIR WWHM Page A-8, The vault modeled is rectangular 4.75' deep, but the Stormtech chambers
are semi -circular 3.75' deep. As such, the model over estimates the volume. Please provide an
accurate WWHM model of the proposed system. The design has changed to underground
detention tanks. The WWHM calcs have been revised to use 54" dia tanks with 6" dead
storage. Modeling reflects 1551f of tank. 140 If of tank is proposed with the remaining
storage provided by the 4 — 54" dia manholes. See updated drainage report.
2. TIR Downstream Drainage Analysis: The analysis is stamped by an agricultural engineer. The DOE
manual and Edmonds regulations require the report be prepared and stamped by a Professional
Engineer licensed in the State of Washington in Civil Engineering. I have stamped this report.
3. TIR Downstream Drainage Analysis Page 3: The report references a stormwater supplement to
the Edmonds code. The 2017 Edmonds code uses an addendum and checklists. The supplement
is for the superseded 2010 code. Revised.
4. TIR Downstream Drainage Analysis Figure 4 and Pages B-11 through B-18: The analysis appears
to be for an older version of the design and does not reflect discharging to the existing storm
drain system in condominium complex north of the project site. Revised.
5. Sheet C3.1: The callout for the segmental wall on the left side of the sheet is cutoff. Please
adjust the callout for readability. Revised.
6. Sheet C3.1: Label the 445 contour. Added
7. Sheet C3.1: The note "SEE SHEET C4 FOR OFFSITE STORM LINE" should reference Sheet C3.2
Revised.
8. Sheet C3.1, Structure Table: CBs 16, 18, 20, and 21 have 8" of cover. The City of Edmonds
requires a minimum of 12" cover for non -driven surfaces. Revised.
9. Sheet C3.1, Structure Table: CB #25 is mislabeled 24. Revised.
10. Sheet C3.1, Pipe Schedule, Pipes L, N, and Rare listed as 2% Min. They calculate to 5.03%, 17.3%,
and 20.0% respectively. Revised.
11. Sheet C3.1: Detention system specifies a chamber system with an open bottom. The geotech
does not recommend infiltration. Additionally, the proximity of the retaining wall immediately
to the east will express "infiltrated" groundwater. The bioretention planter also infiltrates and
therefore does not meet the geotech's recommendation. The design has changed to
underground detention tanks. The BioRetention Planter is not modeled to infiltration runoff;
it is designed to provide treatment only with underdrain and overflow designed to discharge
to the detention tanks.
12. Sheet C6.2, Detail 1: The lower orifice is shown as 1.00 in. The WWHM modeling was performed
with a lower orifice size of 2.0 in. WWHM calcs revised. 1" orifices used.
