All sidewalks shall be laid upon a four-inch bed or foundation of well-compacted gravel or coal cinders, covered by at least one inch of sand and having an inclination toward the gutter. Where bricks are used in the construction of any sidewalks outside of the business portion of the city, the bed or foundation shall have a convexity of one-half of one inch in the center, and bricks used in the construction of any sidewalks shall be what are known as hard paving brick and shall be laid diagonally across the walk. The whole work of grading and laying down of sidewalks, whether done by the city or the owner of the respective lots or parcels of land abutting upon the same, will be under the supervision of the committee of the Council on streets and sidewalks or Street Superintendent and subject to their approval.
