RE: Plan Check #2007-0640
Project: New Townhouses (Building A)
Project Address: 23004 Edmonds Way
During review of the proposed plans for the above noted project, it was found that the following
information, clarifications or changes are needed. Provide written responses to each comment and
where changes can be found on the plans. Please resubmit to Manie Harrison, Permit Coordinator.
1. On Sheet AO.1 under contractor coordination notes, specifically note in one list separate permits
and deferred submittals for this project. It appears that you intend mechanical/HVAC,
plumbing, fire sprinkler, fire alarm, State electrical, and fire connection to be separate permits.
Common deferred submittals are shop drawings, steel stairways, guardrails, listed and tested fire
stopping assemblies, etc. Please clearly note for both so there is no confusion what is not
included with this main building permit.
2. The "Existing Conditions" plan on Sheet AO shows existing property lines that must be removed
or relocated so that buildings do not cross property lines. Contact Planning Division for
appropriate procedure.
3. Sheet 20/AO.1 Townhouse Lot Perimeters shows that lot lines will be placed between each
dwelling unit and building. Clearly note on the plans if the subdivision will take place before or
after construction of the buildings. If after building construction, it is the architect's
responsibility to insure that the City approved construction plans for the building must address
all code requirements with the intent of placing future lot lines between units (building
enclosure documents are also required as noted below). If the subdivision will take place before
building construction, a survey (prepared by a State Licensed Land Surveyor) will be required
prior to pour of the foundation wall to insure that the building wall(s) are located on the property
lines (building enclosure documents per RCW 64.55 are only required if the developer elects to
do them per RCW 64.55(6)(b)).
4. For Building Enclosure documents, submit 2 sets of plans and details stamped and signed by an
architect or professional engineer, separate from the main construction plans (the City does not
review and approve Building Enclosure documents for compliance with RCW 64.55). In
addition to Building Enclosure plans, the design professional stamping the plans must also
submit a Tetter stating that "The undersigned has provided building enclosure documents that in

addition to Building Enclosure plans, the design professional stamping the plans must also
submit a Tetter stating that "The undersigned has provided building enclosure documents that in
my professional judgment are appropriate to satisfy the requirements of RCW 64.55.005
through 64.55.090. "
5. Lot lines are proposed to go through the middle of fire sprinkler room connecting Building A
and Building B, which would not comply with fire separation distance requirements of the
building code (LBC Chapter 7). The fire sprinkler rooms also appear to connect these 2
buildings, requiring revised allowable area and height calculations to justify Type of
Construction (IBC 503). This would also require Building B to be constructed entirely under the
IBC rather than the IRC. Please revise to show code compliance.
6. Provide construction details of the fire sprinkler room and cross reference where they apply on
the plans.
7. Since each parking garage is accessed only by the dwelling unit it serves, revise occupancy to U
rather than S2.
8. Under `Building Code" information on Sheet A0, the allowable area increase per IBC 506.3 for
the R2 occupancy is only permitted with an NFPA-13 system (plans note a 13R system).
Revised garage areas to U occupancy and revise allowable area and height calculations
accordingly. Also see IBC 406.1 for more information specific to U occupancies.
9. On the site plan, label all decks, cantilevers, patios, stairways, canopies, dumpsters, etc.
Dimension distances to property lines.
10. Provide stair construction detail for exterior stairways including rise, run, width, handrails on
both sides, handrail height, handrail extensions, dimensioned landings, etc.
11. Expand 1/A2.1 by adding dimensions to required setback line to clearly show that all buildings,
patios, canopies, retaining walls, etc. meet setback or encroach permitted distances into setback.
Clearly label all items.
12. If proposed lot lines will separate dwelling units, a 2 -hour Fire Wall will be required (IBC
503.2) with no openings permitted and must be constructed per IBC 705. Provide construction
section details clearly showing a continuous 2 -hour Fire Wall from foundation through to a point
30" above the roof (unless exception is used per IBC 705.6.). Also see provisions for stepped
roofs. Provide listed and tested 2 -hour wall assembly with an STC of 50 or more. The fire wall
must be constructed to allow collapse of construction on either side of the wall without collapse
of the wall itself for the 2 -hour time period (IBC 705.2). This must be coordinated with the
structural engineer, including floor and roof sheathing which cannot be continuous through the
fire wall. Clearly show how fire walls will terminate at the exterior wall, and through eaves,
decks, etc. (or if exception is used, clearly note and show compliance). Clearly note what
penetrations are proposed at the fire wall (TBC and provide listed and tested fire stopping
assemblies applicable to the type and size of penetrations.
13. Since 2 -hour Fire Walls will be creating separate buildings at proposed property lines, provide
floor area and occupant load information for each dwelling unit (include fire sprinkler room
where applicable).
14. Revise 7/A0.1 to show correct occupancies and fire ratings.
15. The listed and tested assembly for the exterior rated wall calls for Dens Shield on both sides.
Please confirm this is what you are proposing. You may want to look at the Exterior Wall
section of the Fire Resistance Design Manual (WP 8XXX) or UL assemblies for one that will
meet your design.
16. Exterior wall coverings 5 feet or less to real or imaginary property lines must essentially be non-
combustible by not exhibiting sustained flaming per NFPA 268. Revise elevation views and
provide manufacturer's information for siding to show that it meets this requirement.
17. Sheet Al0.1 window and door schedules are missing from the plans.
Page 2 of 3
1 S. Provide a letter from the geotechnical engineer of record that they have reviewed the plans and
they comply with the recommendations in their report from 7/1.0/2006, or provide addendum to
report with additional recommendations.
19. Special Inspections will be required as follows:
Geotechnical inspections:
a. Excavation, grading and site preparation
b. Shoring installation and monitoring
c. Placement of fill and compaction
d. Soil bearing verification
e. Foundation and retaining wall drainage
f. General Site monitoring during wet weather construction
Structural inspections:
g. Concrete construction
h. Structural steel fabrication and erection
i. Anchor bolt and holdown installation
j. Shearwall and diaphragm nailing
20. See attached comments from City Consultant. Provide written responses to each comment and
where changes can be found on the plans

STRUCTURAL COMMENTS
General
Engineer of Record (EOR), please reference where to use each detail. There is a
note that states all details may not be used and for the contractor to verify, but the
design professional should specify which detail to use where and cross off details
that do not apply for this permit. Please modify the drawings to clearly show which
detail is to be used where. I will do my best to try to verify where each detail is to
be used and review the set based off this but the drawings should be revised to
check the minimum code requirements.
2. FOR, the architectural drawings show decks being used supported by diagonal
rods. Submit an analysis and details for these conditions. I was unable to find
where this was done by the FOR.
3. EOR, there appears to be items that do not pertain to this structure. For example,
portions of the quality assurance plan. Please cross off all portions that do not
pertain to this permit.
Sheet A4.2 Wall Sections, Details

24. Detail 6: EOR, please submit an analysis for the attachment of the wood ledger to
the concrete wall. Also, please specify the required edge distance of the KB3 to the
concrete edge.
25. Detail 6: I called Hilti at 1-800-879-8000 and asked them what the minimum edge
clearance for the anchor specified is. They told me the edge distance must be a
minimum of 4-1/4 for 518" bolt no matter how the load is applied. The load must
be modified accordingly to their technical guide for influence of edge distances.
For the full value you must have 8-112". Based off the detail it appears this will not
be met. EOR, please modify accordingly or submit documentation that the detail
will support the loads as detailed. Hilti product technical guide
