(1) Concrete. Sidewalks shall be constructed of concrete with a compressive strength of not less than 3,000 pounds per square inch, using not less than 500 pounds of cement per cubic yard of concrete, and with a maximum slump of four (4) inches. In cold weather, calcium chloride may be added by dissolving in the mixing water an amount not exceeding two percent (2%) of the weight of the cement in the concrete mix.

(2) Other material. Other materials such as bricks or flagstone may be used for aesthetic effects where approved by the approving authority or as otherwise provided in Section 10.358, Central Business District. Such material will have flat surfaces suitably finished for sidewalk use. Materials submitted shall be comparable in strength to concrete and shall be placed with suitable mortar to provide a permanent, maintenance-free sidewalk. (Effective Dec. 1, 2013.)

(3) Construction. Sidewalks shall be constructed according to the structural specifications prescribed by the City Engineer. A sidewalk shall be nominally four (4) inches thick, except where a sidewalk crosses a driveway it shall be nominally six (6) inches thick. A sidewalk shall slope one-quarter (1/4) inch per foot toward the curb. The edge of the sidewalk nearest the curb shall be at an elevation equal to the rate of one-quarter (1/4) inch per foot above the curb.

Where a residential building site fronts on an unimproved residential street the requirement to improve sidewalks may be waived if the development qualifies for deferral of street frontage improvements as per Section 10.432, Street Improvement, Deferred.

(4) Width. Sidewalks shall be five (5) feet in width except in the C-B district of the city where sidewalks shall be as per Section 10.358 of this code and shall extend from the property line to the curb. Required sidewalk width does not include curb width. All planning, design and construction documents shall clearly state that at least five (5) feet of the sidewalk is to be clear of obstructions such as sign posts, utility and signal poles, mailboxes, parking meters, fire hydrants, trees, and other street furniture.

(5) Alignment. Sidewalks on arterial and major collector streets shall be set back a minimum of ten (10) feet from the back of the face of curb (See the street diagrams for arterial and collector streets above), unless curvelinear as provided below.

Sidewalks on all other streets shall be located a minimum of eight (8) feet from the back of curb unless curvelinear as provided below. If there are existing sidewalks on the same side of the street in the same block, then the sidewalk location shall be determined by the approving authority.The approving authority may approve curvelinear or meandering sidewalks for aesthetic purposes or for other reasons such as topography or to avoid existing trees. Where approved, such sidewalks shall tie to adjacent property lines in such a manner as to allow standard sidewalk construction on that property. (Effective Dec. 1, 2013.)

(6) Repair. All projects subject to Site Plan and Architectural Review shall be required, as a condition of approval, to repair all frontage sidewalks as determined by the Engineering Department. When attached as a condition of approval of a Site Plan and Architectural Review application the sidewalk maintenance procedures set forth in Chapter 3, Section 3.025, Notice on Hearing of City Repair of Sidewalks, through 3.035, Notice of Sidewalk Repair, are hereby superseded.

(7) Permit for Sidewalk Work. Before beginning the construction, reconstruction, or repair of a sidewalk the developer shall apply to the City Engineer for a permit. If the sidewalk conforms to the provisions of this section, the City Engineer shall establish the grade of the sidewalk, if not already established, and issue the permit upon payment of a permit fee established and periodically amended by ordinance of the City Council.
