During review of the above noted application, it was found that the following information,
corrections, or clarifications are needed. Please submit revised plans/documents with a written
response to each of the items below to a permit coordinator.
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, standard details and development code can be referenced on the City
website.
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.
a. A 3.3% inspection fee is calculated for the project based on 100% of the City approved
estimate for the entire project improvements.
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.
3. City standard details have been updated and renumbered. Please refer to City website and
reference and incorporate new details into plan set.
4. As noted during design review, a right-of-way dedication will be required at the building permit
phase of this project to clear up an existing right-of-way/parcel boundary discrepancy. Please
provide a site plan, meeting Snohomish County recording requirements, that shows the specific
dedication area. This will accompany the ROW dedication document. Once receiving the site
plan, City staff will present the topic at a Council committee meeting. Following that meeting
and approval at the committee level, the item will be placed on the council consent agenda.
Recording of the dedication will take place following that.
A Stormwater Covenant is required to be recorded against the property based on the proposed
stormwater facilities for the project. Please complete the attached covenant, including
notarization and any 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, the location of
facilities are to be verified (by field inspection and asbuilt) and then the covenant will be
recorded.
Sheet F-0.4 — TESC NOTES
1. Replace the following erosion control details with City standard details: CB protection,
construction entrance, and filter fabric fence.

Please insert this note which addresses compost amended soils.
Sheet F-1.1 - LAYOUT PLAN
1. Layout Note 42 states "see civil drawings for storm drainage and other general notes". There
does not appear to be a separate civil plan set and instead civil type plan sheets have been
included within the F-series sheets. Please revise note accordingly.
2. It does not appear as though Layout Note 14 has been referenced in plan view. Please revise
accordingly.
3. Sheet F-1.3 indicates a new storm line from CB #1 to the existing CB in the ROW, which will
run through City sidewalk. Please show limits of sidewalk restoration on this plan sheet. In
addition, refer to Sheet F-1.3 comments for storm line layout.
4. Plans indicate a "Curb Cut at Sidewalk" for replacement of the curb ramps at the driveway
approach on 2161h St SW. Thank you for referencing Note #20 which provides additional info.
Please revise note to more clearly indicate curb ramp replacement and add leader to show
replacement of both curb ramps is required.

Reviewer: Zack Richardson, PE
City of Edmonds, Stormwater Engineer
Recommendation: I recommend that BLD20180708 be withheld until the comments
below are adequately addressed. All comments below were provided as preliminary
comments under PLN20180014.
Review Comments:
1. The pervious pavements may remain as modelled (50/50) provided that any
underdrain is elevated above the bottom of base course to promote infiltration.
2. The applicant has verbally stated that no work to add impervious surfaces that
were not fully permitted and mitigated through the City has occurred; it is believe
that the retrofit requirement will not impact the project, but the applicant must still
provide written documentation of this.
3. Grading and drainage plans must be stamped and signed by the overseeing civil
engineer prior to construction approval (electrical engineer needs to sign
electrical plans too).
4. CB #13 now appears to be just barely over 5' from invert to top; add notes or
update plans as needed to reflect need for Type 2 if invert found to be more than
5' from rim elevation (or conduct pothole prior finalizing design).

DECLARATION OF COVENANT
Private Stormwater Facility
WHEREAS, the undersigned Declarant(s) have installed one or more stormwater
facilities under Edmonds Community Development Code Chapter 18.30 known as a "low impact
development best management practices (LID BMP)" as selected below:
❑ Permeable Pavement ❑
❑ Rain Garden / Bioretention Cell ❑
❑ Drywell ❑
Infiltration Trench
Gravelless Chamber
Other
WHEREAS, the City of Edmonds has allowed installation of the LID BMP, subject to the
execution and recording of this Declaration of Covenant; NOW, THEREFORE,
THE UNDERSIGNED DECLARANT(S), being the owners of the real property ("the
Property") located at the following address:
in the City of
Edmonds, Washington, and legally described on Exhibit A attached hereto and incorporated
herein by this reference as if set forth in full, hereby covenants and agrees, on behalf of
himself/herself/themselves/itself and his/her/their/its successors and assigns, as follows:
Declarant(s) warrant that he/she/they are the owners of the property described on Exhibit
A and have the authority to impose this covenant on the property and bind all future owners,
successors, and assigns of the Declarant(s). The Declarant(s), future owners, successors,
and assigns of the Declarant(s) shall be referred to collectively as "Owners."
2. The Owners of the Property agree that the Property contains one or more stormwater
management facilities referred to as an "LID BMP," which was installed to mitigate the
stormwater quantity and quality impacts of some or all of the impervious or non-native
pervious surfaces on the property. "Low impact development" means development
conducted in a way that seeks to minimize or completely prevent alterations to the natural
hydrology of the site. Low impact development includes site planning and design to reduce
alterations of natural soil and vegetation cover, minimize impervious surfaces, and specific
practices that help to replicate natural hydrology such as permeable pavements, green
roofs, soil amendments, bioretention systems, and dispersion of runoff.
3. The Owners shall maintain the size, placement, and design of the LID BMP as depicted on
the approved site plan, Exhibit B, and design details shall be maintained and may not be
changed without written approval either from the Engineering Division of the City of
Edmonds or through a future development permit from the City of Edmonds. Chemical
fertilizers and pesticides shall not be used where LID BMP is located. All costs of
maintenance and repair shall be the sole responsibility of the Owners.
4. The Owners shall inspect LID BMPs annually for physical defects. After major storm
events, the system shall also be checked to ensure that the overflow system is working
properly. The Owners also shall maintain all LID BMPs so they function as designed on a
year-round basis.
5. The City of Edmonds is hereby granted by the Owners the right, but not the obligation, to
enter upon the Property described on Exhibit A at all reasonable times for the purpose of
inspecting the private stormwater LID BMP facility. If, as the result of any such inspection,
the City of Edmonds determines that the LID BMP is in disrepair, requires maintenance or
repair, or is otherwise not functioning as provided in the BMP site plan, the City Engineer
or his designee shall have the right, but not the obligation, to order the Owners to maintain
or repair the same.
6. If the City of Edmonds determines that the LID BMP requires maintenance or repair
pursuant to Section 5, the City of Edmonds shall provide notice to the Owners of the
deadline within which such maintenance or repair must be completed. Said notice may
further advise that, should the violator fail to perform required maintenance or make repairs
within the established deadline, the work may be done by the city or a contractor designated
by the City Engineer and the expense thereof shall be charged to the Owners. The City's
officers, agents, employees, and contractors shall have the right, which is hereby granted
by the Owners, to enter upon the Property described on Exhibit A in order to perform such
work. The Owners shall bear the cost of all work performed.
7. The Owners shall indemnify, defend and hold harmless the City of Edmonds, its officers,
officials, employees and agents from any and all claims, demands, suits, penalties, losses,
damages, judgments, attorneys' fees and/or costs of any kind whatsoever, arising out of or
in any way resulting from the approval of the LID BMP(s), the installation and presence
of the LID BMP(s), and the acts or omissions of the Owners, their officers, employees,
contractors, and agents relating to the construction, operation and maintenance of the LID
BMP(s) on the Property, except for the City's intentional and willful tortious acts, and
waive and release the City of Edmonds from any and all claims for damages and injunctive
relief which the Owners may themselves have now or in the future, by reason of the
construction, maintenance and operation of said LID BMP(s).
8. This covenant shall run with the land and be binding upon the Owners.
