Service Description: The hillside data set was created for the City of Boise Planning and Development Services and Public Works Department to delineate areas where slopes are over 15%, and areas where potential erosion and sedimentation problems exist within the Boise Area of Impact. To alleviate potential erosion damage, properties within the Boise Area of Impact that reside in a hillside area are subject to specific restrictions and conditions for all development and permit applications.

Description: This is a polygon data set representing areas designated as hillsides, by Boise City, within the Boise Area of Impact. Section 11-14-02.1 of the Boise Municipal Code defines hillside areas as “any topographical slope” that “exceeds fifteen percent (15%) or where adverse conditions associated with slope stability, expansion soils, high water table and springs, erosion or sedimentation are present.” Hillside areas were originally defined based on visual analysis of digital 7.5’ USGS topographic maps and interpretations made by City of Boise Public Works Department staff. The hillside polygons represent generalized areas where relatively steep slopes or adverse conditions are present. Boise City GIS developed the hillside dataset under direction from the Boise City Public Works Department staff. This data is updated upon request by the Boise City Public Works Hillside Engineer Technician, and is current to the date it was published.
