RE: Plan Check # 2007-1106
Project: Edmonds Arbor Court Townhomes
Project Address: 23812 Edmonds Way (BUILDING 2)
During review of the above noted application, it was found that the following information,
corrections, or clarifications are needed. Please redline plans or submit two (2) sets of revised
plans/documents (affected sheets only) with a written response to each of the items below to a
Permit Coordinator.
1) Please add the following information to the site plan.
■ On the site plan clearly show all of Edmonds Way and exactly where the PK Nail used for
the datum point is located. If it is not located on the shoulder or somewhere safe to perform
height inspection then an alternate datum point will need to be chosen or established.
■ Any common areas (i.e. mail boxes or dumpster enclosure, etc.) must be accessible. Please
show location and accessibility requirements if there will be any such common areas on this
site.
You may redline plans or resubmit three (3) new site plans scaled no smaller than 1 "=20' and
one on paper no larger than 8 %" x 14".
2) For the units that have a den on the lower floor please revise the design or label this as storage.
When a room has a closet it is considered a sleeping room and sleeping rooms are prohibited
from exiting into a garage. This room can not be used for anything other than storage.
3) Clearly note on the plans if a 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. 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) 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. In addition to
Building Enclosure plans, the design professional stamping the plans must also submit a letter
stating that "The undersigned has provided building enclosure documents that in my
professional judgment are appropriate to satisfy the requirements ofRCW 64.55.005 through
64.55.090. "
5) Sheet A5.0
a) Specify and provide copies of listed and tested fire rated assembly to be used. Note,
chosen assembly must be rated for exposure from both sides.
b) Fire blocking is required at the floor lines and roof -ceiling line of the air space created
between the walls. Show the fire blocking and call out the material (IRC R602.8). You
may want to coordinate with your contractor since this can be tricky to build.
c) Clarify that fire rated walls will extend to the underside of the structural roof sheathing.
d) On the roof plan, show that no penetrations are permitted for a distance of 4 feet on each
side of the two walls.
6) Provide letter from Geotechnical Engineer of Record stating that they have reviewed the plans
and that they are consistent with the report recommendations.
7) Special inspections are required for the following. Complete the enclosed special inspection
agreement signed by the owner, the general contractor and the special inspector and submit to
the City for approval prior to issuance. (A separate form is required for each separate special
inspector).
• Excavation/Grading/Site Prep
• Soil Bearing Verification
• Placement of Fill and Compaction
• Footing drains
• General Site Monitoring during wet weather construction
• Structural special inspections noted on 51.1
8) See attached structural comments from city consultant. Respond to each item in writing.

ORDINANCE COMMENTS
General
1. Please note that per R317.2, the rated assembly requirement for townhouses within 3
feet of the shared property line, is a one-hour rated wall assembly for each unit, or a
common 2 -hour wall provided some conditions. Drawings appear to reference one-
hour rated assemblies at the shared property lines, when these assemblies must in fact
comply with (2) one-hour rated assemblies or similar. Please review and modify all
relevant details and note references accordingly, as required per code. R317.2 and
R302.
Sheet A-2.0: Building #1 Floor Plans / Roof Plans
2. It appears that the Wall Legend references may need modification, as necessary to
meet the required fire -resistance -rated wall assemblies for townhouses. R317.2 (See
Comment 1)
3. It appears that the wall tag "C" (plumbing both sides), applies at 3`d floor laundry
(Unit D)1 bath (Unit A), rather than wall tag "B" as currently shown. Please clarify.
4. Mechanical equipment in garages of Unit Types A and B must be installed with
sources of ignition 18 inches minimum above the garage floor. M1307.3
5. Water heaters/ appliances must be strapped at upper third and lower third. M1307.3

at the floor and ceiling lines as well as horizontally at intervals not exceeding 10 feet.
Please indicate on wall details. IRC R602.8
Sheet A-5.0: Wail Types
S. Please note that for "Townhouses," walls separating dwelling units shall be
constructed of either two structurally independent 1 -hour wall assemblies, or one

only supports 6 kips It appears that footing pad F2 will be insufficient at Unit A and
Unit B exterior corners. Please modify accordingly.
38. Please clarify how the lateral loads of the second floor horizontal diaphragm are
being collected at the garage headers into the adjacent exterior shear walls at first
story.
39. Based on the location of hold downs, the garage entry shear walls appear to cross unit
