A determination has been made that this project will be a Category II Hillside project due to the nature of surrounding slopes. 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 geotechnical report with the possibility of a global slope stability analysis (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, or having a backslope greater than three feet horizontal to one foot vertical (these requirements will be assessed again at the time of occupancy).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.
