An integral concrete sidewalk and curb section bears on an aggregate base with a minimum thickness of four inches over a prepared soil base. The concrete slab features a four-inch thickness, a maximum slope of two percent sloping toward the adjacent asphalt or concrete paving, and a six-inch curb height dropping to one foot six inches at the gutter line. The curb width measures six inches at the base with a minimum four-inch subgrade clearance. Finish grade transitions meet the back of the sidewalk as indicated in the general notes.
