RE: Plan Check: BLD2019-0026 —1st review
Project Address: 549 Paradise Lane
Project: Paradise Heights civil improvements
Scope: Site excavation/grading/retaining walls/infiltration system/storm and
foundation drainage and other related work for proposed structures constructed under
BLD2019-0025
Please be advised that the building plans for the above referenced project have been disapproved
for the purposes of obtaining a building permit. During a review of the plans by the Building
Division for compliance with the applicable building codes, it was found that the following
information, clarifications, or changes are needed. Reviews by other divisions, such as Planning,
Engineering, or Fire, may result in additional comments that require attention beyond the scope of
this letter.
A complete review cannot be performed until the revised plans/documents, including a
written response in itemized letter format indicating where the `clouded' or otherwise
highlighted changes can be found on the revised plans, have been submitted to a Permit
Coordinator. Only those sheets specifically referenced as follows need to be resubmitted.
Resubmittals must 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 from 8:30am-12pm on Wednesdays.
On the provided geotechnical report prepared by Samuel E. Suruda, G.I.T., for Earth Solutions NW,
LLC — ES-5839 — dated March 5, 2018:
1. Provide a signed stamp/seal of a geologist licensed in the State of Washington that prepared,
or was in responsible charge, for the engineering geology report per Washington
Administrative Code (WAC) 308-15-075.
2. Provide confirmation that a review of the plans for the final design of the proposed
residential structures and other site elements has been completed to verify the incorporation
of the geotechnical recommendations provided in the report.
General plan review note: The following plan review comments regard the Building Division
concerns after a review of the submittal documents prepared by Donna Breske & Associates, LLC.
On sheet 1 of 6 — SITE PLAN FOR PARADISE HEIGHTS HLD LLC:
3. SITE PLAN
a. Indicate on the plans the top of the north -descending steep slope with a gradient in
excess of 40 percent referenced in the geotechnical report prepared by Samuel E.
Suruda, G.I.T., for Earth Solutions NW, LLC — ES-5839 — dated March 5, 2018. Of
particular concern is the establishment of the slope hazard area and the required
setback from it for the placement of the proposed infiltration systems and the
proposed retaining walls as noted on page 14 of the above referenced geotechnical
report.
b. Provide on the plans a detail, and a reference to it, for the minimum required
construction of the `KEYSTONE BLOCK WALL' located along the northwest
portion of the lot. A detail found on sheet `4 of 6' — GRADING FOR PARADISE
HEIGHTS HLD LLC — may be used to guide proper review construction, and
inspection — see also plan review comment V.
c. Provide on the plans a detail, and a reference to it, for the minimum required
construction of the `CONCRETE RETAINING WALL' located along the east,
south, and west portion of the lot — see also plan review comment `5.b'.
d. Identify on the plans the purpose of the two 20 foot wide, 60 feet long elements
located in/below the driveway along the south and west portion of the lot.
On sheet 2 of 6 — ROAD & DRAINAGE PLAN FOR PARADISE HEIGHTS HLD LLC:
4. ROAD & DRAINAGE PLAN - Indicate on the plans the top of the north -descending steep
slope with a gradient in excess of 40 percent referenced in the geotechnical report prepared
by Samuel E. Suruda, G.I.T., for Earth Solutions NW, LLC — ES-5839 — dated March 5,
2018. Of particular concern is the establishment of the slope hazard area and the required

the above referenced geotechnical report.
On sheet 4 of 6 — GRADING FOR PARADISE HEIGHTS HLD LLC:
5. GRADING PLAN
a. Indicate on the plans the top of the north -descending steep slope with a gradient in
excess of 40 percent referenced in the geotechnical report prepared by Samuel E.
Suruda, G.I.T., for Earth Solutions NW, LLC — ES-5839 — dated March 5, 2018. Of
particular concern is the establishment of the slope hazard area and the required
setback from it for the placement of the proposed retaining walls as noted on page 14
of the above referenced geotechnical report.
b. Provide on the plans a detail, and a reference to it, for the minimum required
construction of the `RETAINING WALL' located along the east, south, and west
portion of the lot. The design must be supported by structural calculation prepared
by an engineer licensed in the State of Washington.

6. Section 1 — KEYSTONE BLOCK WALL — Clarify on the plans the provided information
regarding the details for the construction of the `KEYSTONE BLOCK WALLS'. It does
not indicate the minimum 18 inch deep backfill of free -draining material placed along the
height of the wall as specified on page 13 of the geotechnical report prepared by Samuel E.
Suruda, G.I.T., for Earth Solutions NW, LLC — ES-5839 — dated March 5, 2018. The
required minimum `GRID DEPTH' must also be specified on the plans to guide proper
construction and inspection.
The unique and specific nature of the work necessary to complete your project requires special
inspection per IBC 1704. A City of Edmonds `Special Inspection and Testing Agreement' for work
specified in the geotechnical engineering /infiltration reports will need to be completed and returned
prior to permit issuance.
