RE: Plan Check #2007-0643
Project: New Townhouses (Building D)
Project Address: 23010 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. Previous item 2: On the "existing conditions" plan, the label is missing for the dark dashed line
between parcel B and parcel C. The same line is also not labeled on the site plan. Please revise.
2. Previous item 3: Clearly note on 20/A0.1 that this plan is for reference only for "future" lot
perimeters and that the subdivision must first be approved by the City of Edmonds.
3. Previous item 4: The Building Enclosure letter submitted must still be signed by the architect.
4. Previous item 5: Label the type of retaining walls shown at the rear of building E (e.g. concrete,
keystone, etc.). Show the location and extent of the 3' high rockery now shown at the rear of
building F. Coordinate civils, site and landscape plans to show all retaining walls and rockeries,
and cross reference construction details on both site and civil plans. Detail 16/A1.2 is for walls
up to 4 feet high, while some walls shown on the site plan exceed this height. Revised detail
and provide structural calculations for walls over 4 feet high.
5. Previous item 7 & 14: Since you are now designing to the IRC (confirmed with architect
11/29/07), revise code information on Sheet A0:
a. 2003 IRC, 2003 UPC, 2004 WSEC, and 2003 VIAQ
b. R3/[J occupancies
c. Type of heating system (forced air furnace, in -floor hydropic, etc.).
6. Previous item 9 & 11: Show the cantilevers on the east side of building D, and dimension
setback to cantilever. Show the decks and cantilevers on the west side of building D.
Dimension the encroachment of the patios into the east setback area. Some setbacks appear to
have been added to the future lot perimeters plan, but they need to the on the site plan.
7. On the site plan, relocate the "area of work" to be associated with Building D rather than
Building A. Also, the height calc box and elevations need to be added to building D.
8. Provide construction detail showing how prefab concrete stair treads are to be installed.
9. North exterior wall of Building D (previous item 15):

a. 2003 IRC, 2003 UPC, 2004 WSEC, and 2003 VIAQ
b. R3/[J occupancies
c. Type of heating system (forced air furnace, in -floor hydropic, etc.).
6. Previous item 9 & 11: Show the cantilevers on the east side of building D, and dimension
setback to cantilever. Show the decks and cantilevers on the west side of building D.
Dimension the encroachment of the patios into the east setback area. Some setbacks appear to

7. On the site plan, relocate the "area of work" to be associated with Building D rather than
Building A. Also, the height calc box and elevations need to be added to building D.
8. Provide construction detail showing how prefab concrete stair treads are to be installed.
9. North exterior wall of Building D (previous item 15):
a. An imaginary property line needs to be placed between buildings E and F. Assuming it
will be placed per the "future lot perimeters plan", exterior walls of both buildings must
be 1 -hour fire resistive construction with no openings permitted (IRC R302).
b. Clearly show on Sheet A2.1 and A2.2 that the north exterior wall of the building is 1 -
hour fire rated, and cross reference construction details with listed and tested assembly.
c. The exterior wall symbol on the wall key Sheet A2.1 is not the same symbol as shown on
the floor plans. Please coordinate. Also, the reference to 18A/A9.1 is the incorrect wail
type. It should reference wall types B1 and D1 for 1 -hour walls for both types of siding.
d. The north elevation view on Sheet AM shows both stucco and cement fiber siding.
Clarify where one siding stops and the other starts.
e. Revise construction details D/A9.1 and B/A9.1 to show exterior 5/8" Denshield
Fireguard over the exterior sheathing per GA W3 615 on 12/A0.1.
f. Provide a details of the roof termination and trim on the exterior side of the wall. Show
where 2 & 3/A4.2 apply. Exterior wall trim cannot encroach closer than 24" to the
imaginary property line.
10. At rear patio door of each unit, there needs to either be a 36" minimum landing in the direction
or travel or a complying step (IRC R311.4.3). Clearly show/dimension on the unit floor plans.
11. Townhouse separation walls (previous item 12):
a. On Section 16/A4.1 change reference detail number for lid to 4/A4.2.
b. On detail 4/A4.2 label the roof joists so it is clear that the walls are extending to the
underside of the structural roof sheathing. Also, revise the gyp at the underside of the
roof sheathing so it starts at the edge of the double top plate (the structural sheathing
should be continuous over the double top plate with no gyp in between).
c. Revise 1/A0.1 notes to reference 1 -hour exterior walls instead of fire barriers. The town
house separation would be two 1 -hour exterior walls. Also, clarify with notes that you
are using IRC R317.2.2 exception instead of a parapet. Change R2 occupancy to R3.
d. On Section 16/A4.1 the gyp must cover the rim joists of each wall.
e. DetailISC/A9.1:
i. Each wall must be a 1 -hour wall, therefore 5/8" type x gyp (or whatever materials
the listed and tested assembly requires) will be required on the air space side of each
wall. The listed and tested assembly IBC Table 720.1(2) 16-1.1 has been tested for
fire exposure from the inside only which does not meet IRC 8302.1. Both of these
walls must be tested for fire exposure from both sides, so a new assembly must be
provided. Also, the walls together must have an STC rating of 45 or more (IRC
Appendix K).
ii. 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.
iii. Clarify that both fire rated walls will extend to the underside of the structural roof
sheathing.
iv. Clearly show and note on the site plan that no utilities will pass through the
common foundation and townhouse separation walls.
V. On the roof plan A2.1, show that no penetrations are permitted for a distance of 4
feet on each side of the two walls.
12. Previous item 12: Unable to find fire stopping details on the plans.
Page 2 of 3
13. Detail 9/A4.2: The perimeter of the handrail measures more than 6 '/4" therefore it must meet
R311.5.6.3 #2. Clearly dimension handrail to show it meets all requirements of this exception.
14. Detail 14/A4.2: Dimension the height of the guard above finished floor/grade.
15. Detail 7/A1.2: Revise to show the handrail end returned at the bottom of the stair.
16. Previous item 13: Provide floor areas for each dwelling unit.
17. Previous item 18. Still waiting for letter from geotechnical engineer.
18. Previous item 19: Still waiting for Special Inspection and Testing Agreements. These must be
submitted prior to permit issuance.
19. Detail 2/A9.1, clearly note that all wood in contact with concrete must be pressure treated.
20. Overflow drains are required in addition to the roof drains. See IRC R903.4.1 for requirements.
Show on roof plans and provide details.
21. Provide structural calculations for metal grate guard at decks to show that it meets loads in Table
R301.5. (Details on A4.2)
22. See attached comments from City Consultant. Provide written responses to each comment and
where changes can be found on the plans

ARCHITECTURAL COMMENTS
General
1. 40. Structural members supporting occupancy separations shall be the same rating
as the occupancy separations. Please add details and clearly show this on the
drawings. This still has not been modified as required per code. Please modify the
drawing to show the columns in the wall to be individually protected as required
per IBC 714.2.1. IBC 714.2.1
2. 41. AOR, please clearly show the required fire blocking at the stairway as required
per 717.2.2 The response state this is shown on sheet A4.1 but this sheet appears
not to show the required fire blocking as required per sections 717.2.2. Please
modify accordingly. IBC 717.2.2
3. 42. AOR, based off the layout it appears there will penetrations in the firewall
walls. For example, the kitchen areas. Please add the required information for the
member penetration in rated assemblies. For example, between the kitchens. IBC
712.3.2 This appears not to be addressed on the drawings at this time. Please
modify the drawings accordingly.
Sheet A2.1 Building Plans
4. 45. AOR, the code does not allow openings within 4 feet of the separation wall
between the units. Please clearly dimension the sky lights to meet this provision.
IBC 705.6 exception 4 The response state the skylights have been moved back is
fine but still the distance from the wall should be added to the drawings to assure
compliance. Please add this dimension to the drawings.
Sheet A2.2 Unit D 1 & D2 Floor Plans
(This sheets has been changed to reflect just the D 1 Floor plans)
5. Please clarify the call outs for `D2' plans on this sheet. I believe the intent for this
page is to show all D 1 plans.
6. Please add a smoke alarm on the First Floor. R313.1
7. 49. Please add a smoke alarm on each level. One is required on each level and
also giving access to each sleeping room. There is not one shown on first floor or
garage hall way. Please add one on each level. Please add a smoke alarm to the
garage level hallway. R313.1
8. 50. Please add a smoke alarm giving access to the bedrooms. None is shown at
this time. This appears to still not be addressed. There should be a smoke alarm
added to the area giving immediate access to the bedrooms. R313.1
