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) Site plan is missing many of our minimum submittal requirements (i.e. topography elevations, utilities, eaves, height calculations, datum point, impervious surface calculations, lot coverage, etc.). See attached sample site plan. Please submit 3 new site plans scaled no larger than 1"=20' and one on no larger than 8 %" x 14" size paper. 2) On the site plan also show window bumpouts for units 1 and 3. 3) On the site plan clearly label all covered porches and decks and show all stairs for all 4 units. Also, show concrete patio and steps for rear sliding doors on the site plan. 4) As mentioned in the pre -application comments a complete soils report is required for this lot. See attached for minimum report requirements. 5) Update stair detail 1012 to show max 7 3/4" rise. 6) On the floor plan dimension stairs to show that they meet the minimum winder stair requirements of IRC311.5.3.2. 7) Minimum 100 cfm fan is required over the kitchen stove. Note on plans. 8) Energy form submitted is for King County. All though information is similar please transfer to City of Edmonds form (see attached). 9) On the floor plans the fire place manufacture information is per ICBO requirements which no longer exists. Please update this note. 10) Specify on the elevation views the grade slope away from the building. If minimum 6" within 10' is not possible or habitable or useable space is below grade, foundation drainage is required. Provide footing drain detail on foundation sections complying with R405.1 and show required drain locations on the foundation plan. 11) For dwelling unit separation provide copy of listed and tested 1 -hr wall assembly (see attached samples) and incorporate requirements into details 4, 11 and 15. Also add fire block information at the floor and ceiling levels and add attic draft stopping information to the details. 12) See attached structural comments from city consultant.

LATEMPWILDINGIHANDOUT ICODESICOMMNEW BI9 DOC 6 ' i F ov EDS city of edmonds Y� development information Fst. 1890 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 (Current Edition) Washington State Ventilation & Indoor Air Quality Code (Current 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. The code allows flexibility to permit the use of innovative approaches and techniques. This handout however only provides the basic minimum codes for prescriptive compliance. This handout describes the basic prescriptive approach for energy code compliance that 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 U -value of all windows and doors, and the 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 has been created as a means for bringing in fresh outdoor air, and exhausting the interior stale air. The 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. energvy.wsu. edu.
