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 '/2" 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 fixture 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 of RCW 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. Page 2 of 2 Eagle Eye Consulting Engineers, P.S.

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.

Please review and modify all relevant details and note references accordingly, as required per code. 8317.2 and 8302. Sheet A-2.0: Building #7 Floor Plans 1 Roof Plans 2.
