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 '/2" 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 location on civil plans and landscape plans as well. • 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 SWI 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 G1, 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 Al 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) Add the insulation values to the typical framing detail on Sheet G1. 12) 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. 13) 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. 14) The party wall must have a Sound Transmission Class rating of 45 or more (IRC Appendix K). Provide a listed and tested assembly that meets this code, and note the specific requirements of the assembly on Dl/A13. 15) 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 -I on Sheet A-13 accordingly. 16) 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. 17) 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. 18) Revise note on detail D I/A 13 to read "fire -retardant -treated" plywood (as part of parapet exception noted below). 19) Since you have chosen to use the parapet exception, on roof plans and D1 /Al 3 clearly note that no penetrations of any 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 20) Fire sprinkler riser room door must be labeled. 21) Revise "fire caulk" note on D1/A13 to note the fire stopping requirements of IRC 317.3. 22) Note the post to beam connectors on the framing plans. 23) Provide a typical interior and exterior guard details (TRC R312). Loading must meet IRC R301.5 24) Provide a typical detail for island sink loop venting per UPC 909.0. Air admittance valves are not permitted. 25) Smoke alarms are missing on Sheet A6 — please revise. 26) Cross-reference on the floor plans where D3/A13 applies. 27) Specify finish materials under exterior decks and covered porch areas for weather protection. 28) The design professional for the Building Enclosure documents, must submit a written statement 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 54.55.090". 29) Per conversation with you on 6/24108, 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. 30) It appears that a surcharge will be imposed on the foundation walls at the garages. Provide structural calculation to justify foundation wall design at these locations. 31) Special inspections are required by the Geotechnical Engineer of Record 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. • Excavation/Grading/Site Preparation • Placement of Fill and Compaction • Proof Rolling • Soil Bearing Verification • Footing Drain Installation, Subsurface Drainage Installation • General site monitoring during wet weather construction • Final letter 32) See attached structural comments from city consultant.

ADDITIONAL INSTRUCTIONS OR OTHER TESTS Sample and Test Components AND INSPECTIONS: L r f��y,' �. W recti pkted by a Tick. Tekphone No-: Date_ city of edmonds development information 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.energv.wsu.edu.

To 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 home 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 mechanical ventilation: spot ventilation fans, and a whole house ventilation system integrated with your heating system. Spot 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 there 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 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: 5UPPLY DUCT FRESH AIR INTAKE Figure 1. Whole house ventilation system integrated with a forced air heating 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: If your system is not equipped with a mechanical damper, your home will also receive ventilation whenever the system fan operates, including when it's on to provide heating or cooling. Selecting a Whole Dowse 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. TIME OF DAY ON/OFF PINS AUTO: RUN TIME BASED ON TIMER ON: CONTINUOUS OPERATION Figure 2. Typical whole house ventilation timer - 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 Cl 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. Manual 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 handler 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.
