A. Sidewalks. Sidewalks shall be constructed on both sides of all public streets.
1. Residential sidewalks. Residential sidewalks shall be constructed as illustration for a concrete sidewalk. A green space may be provided between the curbing and the front face (side nearest the curb) of the sidewalk and a one foot or more space which shall be provided between the back of the sidewalk and the property line as shown in Figure 8-11, General Sidewalk Detail. The minimum width of residential subdivision sidewalks shall be four feet, one-half inch deep construction and expansion joints, and wire mesh reinforcement requirements are indicated in Figure 8-11 General Sidewalk Detail. Concrete used in the construction of the sidewalks shall be 3500 or 4000 psi mix.
2. Commercial district sidewalks. Figure 8-10, Commercial Detail Curbface Walks and Wingwalk describes the requirements of commercial areas. The minimum width of sidewalks in a commercial area shall be five feet. Re-rods or wire mesh shall be used as reinforcement materials. Concrete used in the construction of the sidewalk and curb shall be 3500 or 4000 psi mix.
3. If sidewalks are not provided, the street grade shall be completed so that additional grading will not be necessary for any future provision of sidewalks.
B. Additional considerations for sidewalks.
1. Sidewalks shall be provided on both sides of a public, or private, bridge where a sidewalk or sidewalks exist entering onto the bridge. All new bridges shall have either one or two sidewalks for the convenience, safety and welfare of pedestrians.
2. Curb ramps shall be provided at all intersections of sidewalks with the corners of the block, crosswalks, pedestrianways and at other locations deemed necessary by the Commission. For details of construction refer to Figure 8-12, Typical Curb Ramp Detail, and Figure 8-13, Typical Intersection Curb Ramp Detail. Detectable warning surface as shown in the figures are required. Consult with the City Street Superintendent for specific construction details.
3. New sidewalks shall be extensions of existing sidewalks when a new subdivision is adjacent to an existing community which has sidewalks.
4. For additional information relative to the care and maintenance of sidewalks refer to Columbia City Code Chapter 97, §§ 97.10 through 97.28 as amended.
5. The Commission may waive the provision for sidewalks for good cause.
C. Crosswalks/pedestrianways/bicycle paths shall be placed at street intersection and, when desirable at mid-block. They shall have a minimum width of six feet. A warning sign shall be posted. A pedestrian operated signal light is required at such places when a state highway is affected.
Consideration should be given for warning devices at other potentially dangerous locations as designated by the Board of Public Works and Safety.
D. Driveway approach/driveway surface drainage. Driveway construction regulations shall be as indicated in city ordinance specifications referenced in § 97.20. Driveways shall be constructed so as not to impede the surface drainage system.
E. Applicability to private streets. The Board of Public Works and Safety or the County Board of Commissioners recognizes that there are justifiable reasons for inclusion of privately maintained streets in new subdivisions such as privacy and security. The Board of Public Works and Safety and the County Board of Commissioners also recognize that the inclusion of privately maintained streets in new subdivisions for the purpose of evading the respective road specifications is not a justifiable reason for such purposes, therefore all streets proposed to be privately maintained shall be required to meet the same specifications, requirements and procedures required by this ordinance for publicly maintained streets during the construction and through the required maintenance period.
