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 Theresa Umbaugh, Senior Permit
Coordinator.
1) Please add the ,following information to the site plan. Resubmit three (3) new site plans scaled 1"=20'
with one additional reduced plan on paper no larger than. 8 %" x 14".
Label and show covered porches, landings, patios, overhangs and dimension distances to property
lines.
Based on the number of overall parking stalls 1 accessible space is required. Show location of
accessible space/with signage details on the site plan (see enclosed sample detail). Coordinate
Iocation on civil plans and landscape plans as well.
Show accessible path of travel from the public street to the building entrances of the 5 -unit
buildings.
■ Show proposed location of all permanent fencing on site plan (coordinate on landscape plan as
well).
■ Height calculations shown on Sheet Al should be placed on Overall Site Plan P1 for all buildings.
2) On the site plans and Sheet SW 1 clearly note and show that all utility lines are stubbed directly
to each townhouse unit. These lines are not permitted to penetrate the party walls separating
dwelling units (including at attic and crawlspace areas). IRC R317.2
3) Provide copies of all recorded easements that encumber the property.
4) Include required over -excavation (as noted in geotech report for foundations) in the grading calculations.
5) Clarify on the foundation plan where the 6", 8" and 10" walls will be used and cross reference to Sheet
G1 for details. On the Gl, note the maximum height of the foundation wall with unequal backfill. The
soils report anticipates excavations up to 7.5' in depth.
6) Provide specific requirements for footing drains as noted in the geotech report.
7) Provide exterior Lighting Summary Form for each building (forms attached).
8) Complete attached energy and ventilation worksheets for each building.
9) Revise occupancy classification information on Sheet AI to R3 since constructed under the IRC.
10) Where a unit plan is "typical" for information, clearly note this on the plans and cross reference so there
is no confusion.
11) The lower floor of the 5 unit buildings must meet Type B accessibility requirements per ICC/ANS1
Al 17.1 (2003 ed) section 1004. For example, the unit entrance, accessible route throughout the floor,
kitchen, bathroom, etc. Provide details and dimensions on the plans to show compliance.
12) Add the insulation values to the typical framing detail on Sheet Gl.
13) On the garage floor plans, note that the ducts in the garage and ducts penetrating the walls/ceiling
separating the dwelling from the garage must be 26 ga minimum.
14) Provide listed and tested assembly for the 1 -hour exterior wall assembly (WAC amendment to IRC
317.2) such as from the Gypsum Fire Resistance Design Manual, UL, or IBC Chapter 7 tables (also see
STC comment below). The wall must be rated for exposure from both sides (not just the exterior side).
Clearly note all requirements of the assembly (including fastener type/size/spacing) so it is constructed
and inspected properly in the field.
15) The party wall must have a Sound Transmission Class rating of 45 or more (TRC Appendix K). Provide
a listed and tested assembly that meets this code, and note the specific requirements of the assembly on
D1/A13.
16) IRC 317.2.1 requires the double 1 -hour exterior walls to be continuous from the foundation through to
the underside of the roof sheathing. Revise detail D-1 on Sheet A-13 accordingly.
17) The party wall must be continuous through the covered porch areas and the attic areas. Provide details
to clearly show this and cross-reference where applicable on the floor plans.
18) IRC 317.2.4 requires that the townhomes be structurally independent (see noted exceptions). The floor
sheathing is not permitted to be continuous through the units (only wall and roof sheathing may be
continuous). Revise structural and architectural plans accordingly.
19) Revise note on detail D1/A13 to read "fire -retardant -treated" plywood (as part of parapet exception
noted below).
20) Since you have chosen to use the parapet exception, on roof plans and D1/A13 clearly note that no
penetrations of a�. ny kind are permitted within 4 feet of each side of the party wall. For example, there
are furnace and fireplace flue penetrations shown on the plans. Please revise and verify. IRC 317.2.2 #2
exception
21) Fire sprinkler riser room door must be labeled.
22) Revise "fire caulk" note on D1/A13 to note the fire stopping requirements of IRC 317.3.
23) Note the post to beam connectors on the framing plans.
24) Provide a typical interior and exterior guard details (TRC R312). Loading must meet TRC R301.5
25) Provide a typical detail for island sink loop venting per UPC 909.0. Air admittance valves are

stamped/signed 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".
30) Per conversation with you on 6/24/08, a townhouse subdivision will be done in the future. Since
the subdivision will take place 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 and buildings.
31) It appears that a surcharge will be imposed on the foundation walls at the garages. Provide

Washington State Energy & Ventilation Codes
Residential Compliance Worksheets
Prescriptive Approach
CODES: Edmonds Community Development Code Chapters 19.30 and 19.35
Washington State Energy Code 2006 Edition
Washington State Ventilation & Indoor Air Quality Code 2006 Edition
The purpose of the State energy code is to provide minimum standards for new or remodeled construction to
achieve efficient use and conservation of energy. This handout provides the basic minimum codes for
prescriptive compliance. The basic prescriptive approach for energy code compliance is the easiest way to
determine or show code compliance. It is a straight takeoff and comparison of total window (glazing) and door
opening area versus the heated floor space. The percentage of glazing shown on the enclosed charts determines
the minimum U -value of all windows and doors for the project, and the insulation R -value for wall, floor, slab
and ceiling insulation. This handout is intended to provide minimum prescriptive compliance and it is not
intended as a substitute for the entire State Energy Code.
Also included in this packet is a Ventilation and Indoor Air Quality Worksheet. Tighter construction and
insulation standards have introduced a vast amount of chemicals and other pollutants into dwellings_ The
process of natural ventilation has also been greatly reduced due to the required sealing of sheathing at walls and
floor levels. The State Ventilation and Indoor Air Quality Code (VIAQ) has been created as a means for
bringing in fresh outdoor air, and exhausting interior stale air. The VIAQ code allows either a manual portal
system or a mechanical system that runs unmonitored on a timer to convey the air.
Forms and additional information about the State Energy and Ventilation Codes can be found on the WEB at
www.energy.wsu.edu.

Whole House Ventilation Systems Integrated
with a Forced Air Heating System'
Your new home has been constructed to use energy efficiently, while
maintaining a healthy indoor environment with goad supply of fresh air.
7-o help you achieve these benefits, we recommend that you take a few
minutes to read these instructions.
Your home has been constructed to the most current requirements of the
Washington State Energy Code (2003 edition) and the Washington State
Ventilation and Indoor Air Quality Code (2003 edition). This means your
home and the ductwork of your heating system have been well sealed,
which limits uncontrolled exchange of air between the indoors and
outdoors. The amount of fresh air provided to your horne is under your
control. You can increase the ventilation rate of your home by opening
windows, or by operating your mechanical ventilation systems. Your home
has two types of rrnechanical ventilation: spot ventilation fans, and a whole
house ventilation system integrated with your heating system.
Fans:
A spot fan has been installed in each bathroom, the utility room and the
kitchen. If your home includes an indoor spa, or any other room that
may need additional ventilation, a spot fan will be included there as well.
The purpose of spot ventilation is to control excess moisture, odors, or
chemical byproducts at the source. It is far more effective to quickly
eliminate moisture and pollutants when they are created than to allow
them to dissipate slowly over time. Controlling moisture reduces the cause of
many molds and protects the finishes of your home. Controlling odors and
chemical byproducts reduces any health hazard that may be associated with
them.
It is particularly important to operate your kitchen fan if you have a gas or
propane range. As well as removing moisture and odors created by cooking,
your kitchen exhaust fan removes the unhealthy byproducts of combustion,
including carbon monoxide and nitrogen oxides.
Recommended spot fan operation:
• Turn on the spot fan whenever moisture, odors,
household chemicals, or combustion byproducts
are present in the room, such as during shower-
ing, washing clothes, or cooking.
• Since moisture vapor, odors, and combustion
byproducts tend to linger, run the spot fan for
up to 60 minutes beyond the activity that
produced them.
Whole house ventilation integrated
with the heating system.
The forced air heating system in this home is
equipped with a ventilation system. This system
includes a fresh air intake connected to the return
air duct (return air is the air that flows into your
heating system), a damper that controls the
amount of air that enters the system, and a timer
that controls when the system operates. To
change the amount of ventilation in your home
adjust the timer to increase or decrease the time
the system operates. In some cases you may also
want to adjust the damper.
Here's how the system works:
SUPPLY DUCT FRESH AER INTAKE
Figure 1. Whole house ventilation system integrated with a forcers air
Beating system.
• When the ventilation timer calls for ventilation,
the furnace fan motor turns on. If the ventila-
tion system is equipped with a mechanical
damper, it also opens.
• The furnace fan pulls fresh air through the fresh
air intake into the return air duct.
- Fresh air is then distributed to the home
through the supply air ducts of the heating
system.
- When the ventilation timer shuts off, the.furnace
fan motor turns off. If the system has a me-
chanical damper, the damper also closes.
Note: 1f your system is not equipped with a
mechanicaldamper, your home will also receive
ventilation whenever the system fan operates,
including when it's on to provide heating or
cooling.
Selecting a Whole House Ventilation
Schedule:
Your contractor has set the timer on your
ventilation system to provide a minimum of eight
hours of ventilation per day. To get the maximum
benefits of the system, you'll want to adjust the
timer to suit your own schedule.
• Run the system more when you expect to be
home, or when more people are expected to be
in the home.
• Set the timer to cycle the system on and off for
short periods. For example, 10 minutes on, 20
minutes off.
•
Use the manual control to turn the system on
when large groups gather in your home.

2 Ventilation System Operating Instructions
Dampers:
There are three types of dampers allowed by the
ventilation code. Figure 3 identifies these dampers
and describes how they work. This system uses the
damper checked below.
❑ Manual Damper
❑ Constant Air Flow Regulator
❑ Motorized Damper
As required by code', your heating contractor has
tested the Flow reate of fresh air brought into your
home and set the damper accordingly.
Manua! Damper Operation:
In normal operating conditions, the damper is
always open, regardless of the settings on the
ventilation timer. The home receives ventilation
whenever air handier fan turns on, or when the
thermostat calls for heating or cooling,
Using the timer to regulate the ventilation rate is
always the best choice. But because this system
provides ventilation to the home whenever the air
handier fan operates, ventilation rates may be
excessive during very cold or very hot weather.
This can mean wasted energy and an
uncomfortable home. In this case, you may wish
to adjust the manual damper. Before doing so,
keep a few things in mind:
• Before you change the damper setting, make
note of the position of the damper adjustment.
You will need to return the damper to this
setting when the extreme weather passes.
• Only reduce the ventilation rate when abso-
lutely necessary.
• Be aware for signs of under -ventilation, includ-
ing smells and high humidity_
