r 's 6. The area where the proposed garage is to be built on is fill material. All footings shall rest on undisturbed soil. Provide foundation design based on the original grade before the fill was placed or provide soils analysis prepared by a licensed geotechnical engineer for the construction of the garage on structural fill. 7. Show how the dwelling meets the requirements of the Washington State Energy Code (WSEC) including R-Value for floors, walls, ceilings. U-value for all new windows and doors and specify energy credits from table 406.2 of the WSEC. Concrete floors in conditioned spaces are required to have a minimum 24 inches of R-10 rigid insulation with thermal break at the perimeter of the slab, including thermal break at slab where the conditioned space transitions into the garage. 8. Provide Ventilation Calculations for the ceilings. The plans for the roof over the Master Bedroom call out 2 x 8 rafters with R-30 (R-38 required) insulation, which would not leave space for ventilation over the insulation. The plans show 2 x 12 rafters over the living room area with R-38 insulation which would not provide sufficient depth for ventilation over the insulation. 9. Provide detail of the guard construction along the stairs at the second floor. Please prepare a response letter showing where each item in this correction letter is addressed on the plan set. Upon resubmittal of the drawings, your application will be given priority and plan review will recommence. All required submittals shall be of sufficient detail and contain sufficient information to ensure that the proposed structure will be constructed in compliance with all adopted codes.
