    A determination has been made that this project will be a Category II Hillside project due to slope, erosion-prone soils, unstable soils, earth movement, and other geologic and hydrologic hazards. In addition to the already submitted documents, additional documents may be required during the CFH Review process.Additional documents that you can expect to provide will be a global slope stability analysis with setback requirements of the pool to wall to slope (please see the Agency Comment for Hillside Retaining Wall Permitting within this PLN); and structural calculations for any retaining wall that is greater than four feet of height, more than one retaining wall when the horizontal interior distance between the retaining walls is less than 10 feet and the total of all retaining walls exceeds four feet in height, a retaining wall having a surcharge, having a backslope greater than three feet horizontal to one foot vertical, or that has structural components (these requirements will be assessed again at the time of occupancy).Due to the observed and reported issues in this area, additional geotechnical requirements may be necessary.A subgrade inspection by a geotechnical firm will be required at the time of construction once the subgrade is exposed and prior to placement of foundation materials or forms/rebar. A report of the inspection will need to be submitted and accepted by PW Hillside before scheduling your inspection with the Building Department and receiving final occupancy.*** Additionally, please contact PW Sewer at msheppard@cityofboise.org and arazaee@cityofboise.org as soon as possible to review the sewer connection requirements; FYI, the sewer line has a lift station. ***NOTE: The hazards of developing and building on property, especially in the Boise foothills, is well known. It is the responsibility of the applicant/owner’s design, geological, and engineering professionals, not the City, to identify, address, and mitigate any hazards to the site. Satisfying these Conditions of Approval is for limited [City purpose] only and should not be relied on for design, geological or engineering purposes. Developer will comply with all requirements of Boise City Hillside Development Code Sections or submit evidence satisfactory to the Boise City Engineer that the proposed development is exempt from the requirements therein stated due to location, topography and/or the absence of adverse conditions associated with slope stability, ground water, erosion and sedimentation.If you would like to discuss this determination, please contact us at HillsideDrainage@cityofboise.org or we can set up a meeting if you prefer.
