All proposed retaining walls or rockeries. 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 1/2" x 14". 2) Guardrails are required to resist 200 psf and the in -fill components must resist 50 psf per Table R301.5. Note on plans. 3) Show how island sink will be vented through the roof or with a loop vent as permitted by UPC 909.0. Air admittance valves are not permitted. 4) Show size and location of crawlspace access (Minimum 18" x 24" in floor or 16" x 24" through perimeter wall). 5) Show size and location of attic access (Minimum 22" x 30"). 6) Provide typical stair detail showing rise, run, handrail, guardrail, headroom etc. complying with R311.5. 7) Per our Retaining wall handout retaining walls located in a critical area must have plans designed consistent with ECDC Chapter 23.80 (including design calculations) and stamped by a Washington State Licensed Professional Engineer. The City reserves the right to require peer review and/or special inspections for all retaining walls in critical areas or their buffers. Whenever a retaining wall exceeds 6 feet in height, peer review and special inspections will be required. 8) See attached structural comments from city consultant. Respond to each item in writing.

Type Area S.F R31U TYPE VB 4232/1008 The above referenced project is in the process of plan review for compliance with The City of Edmonds ordinances and applicable codes (Structural, Non Structural, Energy & Ventilation). The following comments, deficiencies/corrections must be addressed prior to completion of plans review and subsequent issuance of permits. Provide revised plans and calculations along with a written response to each of the items listed below to facilitate a shorter back -check time. SCOPE OF REVIEW The scope of this review is for the ordinance, structural and energy portions of this project. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval. MCEIV60 JUN 2 7 2007 DEVELOPMENT SERVICES 1 GENERAL COMMENTS SHEET 1 1. Smoke Alarm Smoke alarms are not indicated on main level & main level guest room. Please Clarify STRUCTURAL COMMENTS CALCULATION Plan irregularities --- This project plan configuration and its lateral force resisting system contain reentrant corners where both projections of the structure beyond a reentrant corner are greater than 15 %. Please show the calculation of the drag force and specify the strap and nailing for drag strut in the lateral load analysis, especially for the re-entrant corner. The design forces determined shall be increased 25 % per IBC 1620.4.1 and table 1616.5.1.1 plan structural irregularities. 2. Simplified wind load method (method 1) can't be used for this project for the following two reasons: (1) the building is not regular shaped and don't have symmetrical cross section in each direction per IBC 2003 1609.6.1.1 .5. (2) The mean roof height cannot exceed the least horizontal dimension of the building per IBC 2003 1609.6.1. 3. Sheet 4 of 6. Detail " DECK DETAIL " specify (3) 16d to resist 20# / LF for handrail. Per SBC 1607.7.1 Handrail assemblies shall be designed to resist a load of 50 PLF applied in any direction at the top. Please resolve. DRAWINGS 4. Sheet 1 of 6. Main floor plan. Please call out the size of exterior wood posts at the main entrance. 5. Sheet 4 of 6. Detail " DECK DETAIL ". Please call out naturally durable woods or preservative treated wood for the structural members that are exposed to weather. Per IBC 2304.11.2.6 & IBC 2304.11.5. 6. Sheet 4 of 6. Detail " Restrained foundation wall "_ Please provide calculation and verify the adequacy the 9 ft high retaining wall with only a 2 `-8" wide footing. It appears that the overturning safety factor will exceed 1.5 for the case of top connection parallel. If the wall is design top and bottom restrained, then the wood floor diaphragm has to be designed to resist the lateral loads from retaining soil plus the seismic load. All load paths must be complete. (From diaphragm to shear wall to footing) 7. Sheet 4 of 6. Detail " typical pony wall ". Please specify standard hook in the footing per IRC R403.1.3. 8. Sheet 4 of 6. Detail " INTMED BRG SUP. ". show bottom of footing below the undisturbed ground surface is less than 12 ", which is in conflict with IBC section 1805.2. Please clarify. 3 Additional corrections may be required following receipt of corrections and additional information as requested. Your plans are being reviewed concurrently with the Building Department, Fire Department, Zoning Department and Public Works Engineering. Changes, clarifications or additional corrections may be required subsequent to the Building Department plan review when comments are received from the other concerned departments.
