RE: Application #: BLD20181564
Project: Almark Homes - Single Family Residence
Project Address: 926 Sea Vista Place
During review of the above noted application, it was found that the following information,
corrections, or clarifications are needed. Please submit revised plans/documents including a written
response to each item below.
Resubmittals can be made at the Development Services Department on the 2nd floor of City Hall.
Permit Center hours are M, T, Th & F from 8am-4:30pm and on Wednesdays from 8:30am-noon.
City of Edmonds handouts, new updated standard details with new reference numbers, application
and other forms, and development code may be referenced on the City website:
www.edmondswa.gov under Services/Permits and Development.
GENERAL
1) The address "926 Sea Vista Place" has been assigned to this property. Please update plans.
2) General Construction Notes. It looks like you have an older version of our general notes.
Please visit the city website and download the current version. Please be sure to change the
WSDOT/APWA version to 2019.
3) Show all existing and proposed frontage improvements.
4) For road widening, c/g and sidewalk improvements or development of an alley, cross
sections through the ROW shall be provided.
5) Add a 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.
TESC
1) Please provide the location of the temporary stockpile. Add a note that the stockpile is to be
covered within 24 hours
WATER
1) As indicated by the Fire Department, a fire sprinkler system is required for this property.
Typically if there is an existing water service line from the water main to the meter, the
water service line/meter will not be the appropriate size and a new tap will be required. The
applicant will be required to pay for the new tap on the main and the new meter. Please
revise plans to include the following:
a. Please add a note that a 1" meter is to be installed
b. Show the water meter located in the right-of-way, such that the back of the meter is
on the property line. The water meter shall not be located within the driveway. (
c. Please show a 1-1/2" water service line to be installed from the back of the meter to
the house (as required for a combination fire and domestic service).
d. Please label the pipe material and note tracer wire to be installed on the water service
line.
2) Please add a note to the plans that all final restoration shall be completed by the contractor
not the City of Edmonds.
SEWER
1) Entire sewer run shall be shown from the main line to the house.
2) Label pipe material and size. The sewer lateral (from the main to the property line shall be
6". Once on private property the sewer may reduce to 4".
3) Show a 6" cleanout at the property line. Please add a note that the 6" cleanout at the
property line shall have a 12" cast iron lamphole cover with hexbolts.
4) Show a cleanout located within 2' of the house, at any 90' bend, when there is less than 3'
between two 45' bends, and when there is more than 100' between cleanouts.
5) Provide invert elevations at the main, the cleanout at the property line and at the house so
that a minimum 2% slope and minimum 2' pipe coverage can be verified. If the slope of the
pipe exceeds 20% the pipe will need to be anchored.
STORMWATER ENGINEER REVIEW
Refer to separate plan review comments by City Stormwater Engineer, Zachary Richardson.
Please contact Zack directly at 425-771-0220 or by email at
zachary.richardson(a,edmondswa.t!ov with any specific questions you may have regarding his
comments. (NOTE TO REVIEWER: Any comments provided will be located in the
Engineering electronic address files. Combine PDF's with Engineering comments to attach as
one packet in Permit Trax.
1) The following language is to be included with all permit reviews where the Supreme Court
ruling on stormwater vesting comes into play. (Only for lots where a subdivision was
approved prior to 2017 and stormwater the lot was not deferred to the construction of the
lot)
The Supreme Court of Washington issued a ruling on December 29, 2016 regarding the "vesting" of
Stormwater regulations. This ruling upholds the Department of Ecology's regulations for application and
construction dates for projects with Stormwater requirements.

The City of Edmonds has received clarification from the Department of Ecology on what this ruling means for
development applications submitted prior to local stormwater codes being adopted. The stormwater codes in
effect at the time the application for a plat/subdivision is submitted apply to all subsequent building permits if
stormwater is being addressed at the subdivision/plat level. If the subdivision included restrictions or
requirements for the individual lots, (e.g. maximum impervious surface, LID BW s), those requirements
should be recorded for each lot and must be enforced when the individual lot is developed.
Under the municipal stormwater permits the only place that the recent supreme court decision comes into play
is if the developer does not start construction on the plat/subdivision until after January 1, 2022.
For the purposes of the municipal stormwater permits both "application " and "start construction " are defined
in the permits.
Application means at a minimum, a complete project description, site plan, and if applicable SEPA checklist.
Start of construction means at a minimum, the site work associated with and directly related to the approved
project has begun. For example: grading the project site to final grade or utility installation.
Language shall be included on the face of the recording documents for the plat/subdivision that states the
stormwater codes in effect at the time of application for the plat/subdivision shall apply, as long as
construction on the plat/subdivision starts prior to January 1, 2022. If construction does not begin prior to
this date, the stormwater system for the plat/subdivision shall be redesigned to comply with current codes.
2) On January 1, 2017, the City of Edmonds adopted the Department of Ecology 2012(14)
Stormwater Mitigation Manual for Western Washington (SWMMWW). Stormwater design
submittals shall be consistent with the SWMMWW, as modified by the Edmonds
Community Development Code (ECDC) 18.30 and the 2017 Edmonds Stormwater
Addendum. Links to documents and code are available on the City website. Please include
the applicable checklists with your resubmittal.
a. For new SFR projects connecting to a stormwater system approved with a
subdivision approved prior to 2017, the SFR may connect to the system constructed
with the subdivision as long as the proposed impervious surface area does not exceed
that for which the system was designed. If it exceeds the allotted impervious surface
area it shall be designed to the code effective at the time of SFR permit application.
b. SFR permits where the subdivision approved prior to 2017 states the stormwater
system improvements are deferred to the building permit, will be required to meet
the code in effect at the time of building permit submittal.
3) (NOTE TO REVIEWER: 2017 code has a retrofit component) The proposed project site
includes existing impervious surface area. If a stormwater management system was
installed to mitigate the existing impervious surface area, please provide the design
information for the system and show it on the proposed plans. If an existing stormwater
management system does not exist for the existing impervious surface area, the 2017
stormwater code requires that mitigation of 25% of the existing impervious surface be
included in the proposed stormwater design. Please review ECDC 18.30.060.D.5.b.i
regarding the applicability and requirements for the Retrofit bmp.
