Single-family home proposed on nearly 1-acre hillside lot
The plan calls for one house on 0.82 acres and is under city review. Staff say it needs hillside review because of steep slopes and unstable soils, and a geotechnical report and grading plan are on file.

Based on submitted documents and limited overview of the property, 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 (please submit them with subsequent applications), additional documents may be required during the CFH Review process.Additional documents that you can expect to provide will be a site-specific geotechnical report with the possibility of a global slope stability analysis (please see the Agency Comment for Hillside Retaining Wall Permitting within this PLN); structural calculations for any retaining wall system that is greater than four feet in height from top of foundation to top of wall, that has more than one wall when the interior horizontal distance between the walls is less than 10 feet and the total height of all walls exceeds four feet, that has a surcharge, that has 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); and civil plans. Please refer to the Hillside Development Requirements for Technical Reports for grading & drainage plan and geotechnical report requirements.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 to and accepted by PW Hillside (HillsideDrainage@cityofboise.org) before scheduling your inspection with the Building Department and receiving final occupancy.Slope setback requirements will need to be verified against the plat.Above ground swim spas (prefabricated) (or the similar prefabricated, self-contained, self-standing, plunge style “pools”) are approvable as they can be fully above ground and could meet the exemptions from building permits see below (still need electrical/trades as/if applicable) and would not be classified as a true “pool”. The swim spa cannot be built in, below grade, partially below grade, or supported through concrete/earth on the sides (decking/stairs would be okay as long as those would not be supporting the swim spa structure).If it does not meet the exemption criteria per the building code it would not be approvable as it would be considered as a pool. Please keep in mind, above ground swim spas/hot tubs do need to comply with planning setbacks. Per Boise City code:BCC 9-1B-8: IRC ONE-AND-TWO-FAMILY DWELLING BUILDING CODE AMENDMENT, SECTION R105.2, WORK EXEMPT FROM PERMIT: 7. -Prefabricated swimming pools that are not greater than four (4) feet (1219 mm) deep.NOTE: The hazards of developing and building on a property, especially in the Boise foothills, are 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. Please include your application number and address in the subject line.
