RE: Plan Check #2007-0641
Project: New Townhouses (Building B)
Project Address: 23006 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 Marie 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.I 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. 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.
4. 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
(IBC Chapter 7 and IRC R302). 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.
5. Provide construction details of the fire sprinkler room and cross reference where they apply on the plans.
6. Revised occupancy to R3 for the dwelling units, and U for the garages.
7. Under "Building Code" information on Sheet A0, under the IRC allowable area calculations are not
required, and height is limited to 3 stories per R101.2.
8. On the site plan, label all decks, cantilevers, patios, stairways, canopies, dumpsters, etc. Dimension
distances to property lines.
9. .Provide stair construction detail for exterior stairways including rise, run, width, handrails on both sides,
handrail height, handrail extensions, dimensioned landings, etc.
10. 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.
11. If proposed lot lines will separate dwelling units, a 2 -hour Fire Wall will be required (8317.2) with no
openings permitted. Provide construction section details clearly showing a continuous 2 -hour Fire Wall
from foundation through to the underside of the roof sheathing (see requirements of R317.2.2 exception
2). Provide listed and tested 2 -hour wall assembly with an STC of 50 or more. The fire wall must be
constructed per R317.2. Only roof sheathing is permitted to be continuous across the fire wall, which
must be coordinated with the structural plans. Clearly show how fire walls will terminate at the exterior
wall. Clearly note what penetrations are proposed at the fire wall and provide listed and tested fire
stopping assemblies applicable to the type and size of penetrations (see R317.2 exception in common 2 -
hour wall).
12. 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).
13. Revise 7/A0.1 to show correct occupancies and fire ratings.
14. 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.
15. 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.
16. Sheet A10.1 window and door schedules are missing from the plans.
17. 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 7/10/2006, or provide addendum to report with
additional recommendations.
18. 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
19. See attached comments from City Consultant. Provide written responses to each comment and where
changes can be found on the plans

STRUCTURAL COMMENTS
General
1. 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. EOR, the architectural drawings show entry canopy cantilevering off the side of the
wall. Submit analysis or the support of this canopy..
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.

clearance for the anchor specified is. They told me the edge distance must be a
minimum of 4-114 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 8112". Based off the detail it appears this will not
