The height of the walls and loading conditions(e.g., close proximity of wall tiers, etc.) require a building permit, <br /> per IBC Section 105.2 (i.e.,work is not exempt). A geotechnical evaluation and report should be performed per <br /> IBC Sections 1803.1 and 1803.6. The report recommendations should include but are not limited to: <br /> a. General design criteria, including but not limited to surcharge loads behind the walls, maximum soil <br /> slope behind the walls,wall foundation preparation and minimum bearing strength, and drainage <br /> requirements. <br /> b. Evaluation of the wall loads on successive downhill tiers. <br /> c. Evaluation of the upper wall tiers on the existing rockery. <br /> d. Designs for the different wall configurations, including walls requiring supplemental geogrid <br /> reinforcement. <br /> 2. The construction drawings should include project specific sections through the full height of the wall system, <br /> including the existing rockery. See IBC Section 107.2.1. <br /> 3. The minimum spacing between wall tiers should be specified in the drawings, including the existing rockery. See <br /> IBC Section 107.2.1. <br /> 4. The drawings should be sealed and signed by a professional engineer licensed in the state of Washington. See <br /> IBC Section 107.1, and RCW Sections 18.43.010, 18.43.020, and 18.43.070.
