The Council may order the construction of permanent sidewalks upon any street or court in the City and may specially assess the cost of such improvement to abutting property owners in accordance with the provisions of Chapter 384 of the Code of Iowa.
(Code of Iowa, Sec. 384.38)

3. Construction. Sidewalks shall be of one-course construction.
4. Sidewalk Base. Concrete may be placed directly on compact and well-drained soil. Where soil is not well drained, a three (3) inch sub-base of compact, clean, coarse gravel or sand shall be laid. The adequacy of the soil drainage is to be determined by the City.
5. Sidewalk Bed. The sidewalk bed shall be so graded that the constructed sidewalk will be at established grade.
6. Length, Width and Depth. Length, width and depth requirements are as follows:
A. Where residential sidewalks currently exist, residential sidewalks shall be at least four (4) feet wide and four (4) inches thick, and each section shall be no more than four (4) feet in length. Where there are no sidewalks present, or more than seventy-five (75%) percent of the existing panels need replacement, sidewalks shall be five (5) wide, four (4) inches thick and no more than five (5) feet in length.

6. Location. Residential sidewalks shall be located with the inner edge (edge nearest the abutting private property) one foot from the property line, unless the Council establishes a different distance due to special circumstances.
7. Grade. Curb tops shall be on level with the centerline of the street which shall be the established grade.
8. Elevations. The street edge of a sidewalk shall be at an elevation of not less than one-half (½) inch above the curb for each foot between the curb and the sidewalk.
9. Slope. All sidewalks shall have a cross slope of 1.5%.
10. Joint Filler. A one-half (½) inch non-extruding type expansion joint shall be provided between all sidewalks and adjoining backs of curbs and between intersecting sidewalks and between sidewalks and driveways.
11. Finish. All sidewalks shall be finished with a "broom" finish.
12. Ramps for Persons with Disabilities. Ramps required at the intersections shall be constructed to meet the Iowa DOT Design Manual for Accessible Sidewalk Design and inspected by City staff prior to construction.
Whenever any material of any kind is deposited on any street, avenue, highway, passageway or alley when sidewalk improvements are being made or when any sidewalk is in a dangerous condition, it shall be the duty of all persons having an interest therein, either as the contractor or the owner, agent, or lessee of the property in front of or along which such material may be deposited, or such dangerous condition exists, to put in conspicuous places at each end of such sidewalk and at each end of any pile of material deposited in the street, a sufficient number of approved warning lights or flares, and to keep them lighted during the entire night and to erect sufficient barricades both at night and in the daytime to secure the same. The party or parties using the street for any of the purposes specified in this chapter shall be liable for all injuries or damage to persons or property arising from any wrongful act or negligence of the party or parties, or their agents or employees or for any misuse of the privileges conferred by this chapter or of any failure to comply with provisions hereof.
It is the duty of the owner of the property abutting the sidewalk, or the owner’s contractor or agent, to notify the City immediately in the event of failure or inability to make necessary sidewalk improvements or to install or erect necessary barricades as required by this chapter.

2. Openings. Keep open any cellar door, grating or cover to any vault on any sidewalk except while in actual use with adequate guards to protect the public.
