Provide written responses to each comment and where changes can be found on the plans. Please resubmit to Manie 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.1 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 units (building enclosure documents are also required as noted below). 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 (building enclosure documents per RCW 64.55 are only required if the developer elects to do them per RCW 64.55(6)(b)). 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 (the City does not review and approve Building Enclosure documents for compliance with RCW 64.55). In addition to Building Enclosure plans, the design professional stamping the plans must also submit a Tetter stating that "The undersigned has provided building enclosure documents that in City of Edmonds of� } a 7 ;fid PLAN REVIEW COMMENTS BUILDING DIVISION (425)771-0220 DATE- August 21, 2007 TO: Erik Bredberg AD Shapiro Architects FAX: 425-778-3032 FROM: Ann Bullis, Assistant Building Official RE: Plan Check #2007-0640 Project: New Townhouses (Building A) Project Address: 23004 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.

" 5. 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 (LBC Chapter 7). 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. 6. Provide construction details of the fire sprinkler room and cross reference where they apply on the plans. 7. Since each parking garage is accessed only by the dwelling unit it serves, revise occupancy to U rather than S2. 8. Under `Building Code" information on Sheet A0, the allowable area increase per IBC 506.3 for the R2 occupancy is only permitted with an NFPA-13 system (plans note a 13R system). Revised garage areas to U occupancy and revise allowable area and height calculations accordingly. Also see IBC 406.1 for more information specific to U occupancies. 9. On the site plan, label all decks, cantilevers, patios, stairways, canopies, dumpsters, etc. Dimension distances to property lines. 10. Provide stair construction detail for exterior stairways including rise, run, width, handrails on both sides, handrail height, handrail extensions, dimensioned landings, etc. 11. 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. 12. If proposed lot lines will separate dwelling units, a 2 -hour Fire Wall will be required (IBC 503.2) with no openings permitted and must be constructed per IBC 705. Provide construction section details clearly showing a continuous 2 -hour Fire Wall from foundation through to a point 30" above the roof (unless exception is used per IBC 705.6.). Also see provisions for stepped roofs. Provide listed and tested 2 -hour wall assembly with an STC of 50 or more. The fire wall must be constructed to allow collapse of construction on either side of the wall without collapse of the wall itself for the 2 -hour time period (IBC 705.2). This must be coordinated with the structural engineer, including floor and roof sheathing which cannot be continuous through the fire wall. Clearly show how fire walls will terminate at the exterior wall, and through eaves, decks, etc. (or if exception is used, clearly note and show compliance). Clearly note what penetrations are proposed at the fire wall (TBC and provide listed and tested fire stopping assemblies applicable to the type and size of penetrations. 13. 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). 14. Revise 7/A0.1 to show correct occupancies and fire ratings. 15. 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. 16. 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. 17. Sheet Al0.1 window and door schedules are missing from the plans. Page 2 of 3 1 S. 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 7/1.0/2006, or provide addendum to report with additional recommendations. 19. 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 20. See attached comments from City Consultant.

Page 2 of 9 EECE#: EDM 07-30 Valhalla Building A STRUCTURAL COMMENTS General 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. FOR, the architectural drawings show decks being used supported by diagonal rods. Submit an analysis and details for these conditions. I was unable to find where this was done by the FOR. 3.
