[Ord. No. 11-2I 118 §1, 5-12-2016]
A. 
General. The construction of sidewalks will be required to provide pedestrian access to facilities. The extent of sidewalks within a subdivision shall be determined by the Planning and Zoning Commission and approved by the City Council. Generally, sidewalks are required in subdivisions on at least one (1) side of collector and arterial streets. All new constructed walks shall meet the requirements of the current Americans with Disabilities Act. For alterations to existing facilities sidewalks shall meet the requirements, to the maximum extent feasible, of the current Americans with Disabilities Act. The phrase "to the maximum extent feasible" applies to the occasional case where the nature of the facility makes it virtually impossible to comply fully with applicable accessibility standards through a planned alteration. In these circumstances, the alteration shall provide the maximum physical accessibility feasible. Any altered features of the facility that can be made accessible shall be made accessible. All deficiencies shall be reported to the City for approval. Refer to Standard Drawings ST-6 through ST-7.
B. 
Design. On low speed roadways (posted speed of forty-five (45) mph or less), sidewalks are to be separated from the travelway by a barrier curb. In the event a sidewalk is located adjacent to a high-speed roadway, another type of physical separation between the vehicle and the pedestrian such as a guardrail or concrete traffic barrier will be considered. Sidewalks are not to be designated on paved shoulders located behind a mountable curb; nor shall paved shoulders be designated or striped as a pedestrian pathway.
1. 
Sidewalks are to be five (5) foot in width. Freestanding objects mounted on posts, pylons, etc., may overhang a maximum of twelve (12) inches from twenty-seven (27) inches and eighty (80) inches above the ground, although this situation should be avoided whenever possible. Obstacles below twenty-seven (27) inches are not to reduce the sidewalk width to less than three (3) feet. Obstacles reducing the sidewalk width below four (4) feet but not less than three (3) feet, should be corrected, but if not, documented why the sidewalk width was reduced and the obstacle was not moved or corrected at that location and reported to the City.
2. 
Sidewalks are constructed from Class "A" Portland cement concrete, four (4) inches thick, except where 6-inch thickness is required in residential driveways, and 8-inch reinforced thickness is required in commercial driveways and eighteen (18) inches on either side of said area. The sidewalk shall be constructed such that panels are formed using control joints that shall extend to one fourth (1/4) the depth of the sidewalk. If a grooving tool is used to form the control joint, the groove shall not be wider than one fourth (1/4) inch and edged with a one eighth (1/8) inch radius. If the control joints are sawed, the groove shall not be less than one eighth (1/8) inch wide. Whichever method of grooving is used the control joints are to be cut such that the resulting panel lengths are not less than four (4) feet nor greater than six (6) feet. Edges of the slab shall be edged with an edging tool that has a one fourth (1/4) inch radius.
3. 
Surfaces of sidewalks and all parts of the pedestrian network must be stable, firm and slip-resistant. Changes in levels up to one fourth (1/4) inch may be vertical and without edge treatment. Changes in levels between one fourth (1/4) inch and one half (1/2) inch will be beveled with a slope no greater than IV:2H (2:1). Level differences greater than one half (1/2) inch need to be removed or ramped.
4. 
Utility covers, such as for manholes, drainage or water meters, need to have a slip resistant top, as much as possible, and meet changes in level criteria. Lifting holes on covers need to be less than one half (1/2) inch in diameter or be satisfactorily plugged so a cane cannot get lodged in the hole. If grates are located in the sidewalk or other walkway paths, the grates will have spacing no greater than one half (1/2) inch wide in one (1) direction. If grates have elongated openings, then the grates will be placed so that the long dimension is perpendicular to the dominant direction of travel.
5. 
The running slope of the sidewalk should be as level as possible allowing easy use by travelers. For pedestrian facilities the running grade will be a maximum of five percent (5%). If this is technically infeasible, the sidewalk may be consistent with the running grade of the adjacent roadway. The rate of change in grade, the algebraic difference, measured over two (2) foot intervals, is not to exceed thirteen percent (13%).
6. 
Sidewalks are to have a minimum one percent (1%) cross slope to allow for drainage and a maximum of two percent (2%). Any cross slope over two percent (2%) is non-compliant and must be replaced.
7. 
A sidewalk plan must be prepared to show the sidewalk in plan, profile, and typical cross section. This plan may be included as part of the street plan.
8. 
For sidewalks to be constructed on unimproved streets, it is necessary to obtain sufficient field data to determine the probable future grade of the street curb and design the sidewalk accordingly. Additional right-of-way may have to be provided.
C. 
Expansion Joints. Bituminous preformed expansion joints, three fourth (3/4) inch thick and precut to the width of the sidewalk, shall be indicated on the plans eighteen (18) inches on each side of driveways, intersecting walks, curbs, and other locations as required. Expansion joints shall be placed at the locations specified on the plans or standard drawings. Expansion joints shall be placed between the sidewalk and all structures, such as light standards, traffic light standards, traffic poles, and columns, etc., which extend through the sidewalk. Refer to Standard Drawing ST-4 and ST-6 for additional information.
D. 
Ramps.
1. 
General. All ramps shall be constructed to the least possible slope with a maximum allowable slope of 1:12 (8.33%) and a minimum slope of one percent (1%) for drainage. The maximum rise for any run shall be thirty (30) inches. Refer to Standard Drawings ST-7.
2. 
A minimum five (5) foot by five (5) foot level landing area of 0.02ft/ft. Two percent (2%) cross slope or less in any direction shall be constructed at the top and bottom of each ramp, ramp run, wherever two sidewalks cross or wherever a turn is required. Diagonal curb ramps require a four (4) foot by four (4) foot clear space at the bottom protected within the crosswalk markings.
3. 
The minimum width of linear ramps shall be five (5) feet, exclusive of flared sides. In an alteration, the width of the ramp shall match the adjoining sidewalk or a minimum of four (4) feet.
4. 
The minimum width of parallel curb ramps shall be five (5) feet.
5. 
The cross slope on all curb ramps shall be a minimum of one percent (1%) and up to two percent (2%) maximum.
6. 
Grade breaks at the top and bottom of perpendicular curb ramps shall be perpendicular to the direction of ramp run. Grade breaks shall not be permitted on the surfaces of curb ramps, blended transitions and landings within the pedestrian access route. Surface slopes that meet at grade breaks shall be flush.
7. 
At raised islands and/or medians cut-through accessible routes level with the street with a five (5) foot by five (5) foot spacing space shall be utilized. Median cut through length is to be four (4) feet minimum. Detectable warning will be provided at each entrance to the street.
8. 
If a ramp is located where pedestrians must walk across the ramp, or where it is not protected by handrails or guardrails, it shall have flared sides with a maximum slope of 1:12 (8.33%). Curb ramps with returned curbs may be used where pedestrians would not normally walk across the ramp.
9. 
No ramp shall be permitted to project beyond the curb into vehicular traffic. Curb ramps shall be located or protected to prevent their obstruction by parked vehicles.
10. 
All ramps located at public streets and signalized intersections shall have a detectable warning panel installed manufactured by Armor-Tile Transit Systems model ADA-3024-CP or approved equal. Detectable warnings on walking surfaces are required to be truncated domes having a diameter of nine tenths (0.9) inch, a height of two tenths (0.2) inch, and a center to center spacing of one and sixty-five hundredths (1.65) inches to two and thirty-five hundredths (2.35) inches in each direction. The truncated dome panel is to contrast visually with adjoining surfaces, either light-on-dark or dark-on-light. The preferred color contrast is red for concrete and yellow for asphalt surfaces. The surface area for truncated domes is a minimum length of two (2) feet covering the entire width of the ramp or curb opening, excluding the flare sides. The truncated domes are aligned on a square grid in the predominate direction of pedestrian travel to permit wheelchair wheels to roll between the domes. They are to be placed at the bottom of a ramp perpendicular to the path of travel, and parallel to the grade break, or 6 to 8 inches from the front of the curb depending on the type and location of the curb ramp. They are also provided at cut-throughs in islands and medians and shall extend the entire width of the opening at the face of the curbline. Where truncated domes are placed at the bottom of a ramp, the path between the domes shall be parallel to the path of travel on the ramp. At a blended transition or on a landing, the direction of the path between the domes may vary. Where a sidewalk crosses a railroad track, the detectable warning surface shall be located so that the edge nearest the rail crossing is six (6) feet minimum and fifteen (15) feet maximum from the nearest rail. The rows of truncated domes in a detectable warning surface shall be aligned to be parallel with the direction of wheelchair travel.
11. 
Curb ramps shall be provided at all street intersections and at any marked midblock crossings or wherever a sidewalk crosses a curb. Transitions from ramps to walks, gutters, or streets shall be flush and free of abrupt changes (one fourth (1/4) inch or greater change in elevation).
12. 
Curb ramps at marked crossings shall be wholly contained within the markings, excluding any flared sides. If diagonal (or corner type) curb ramps have returned curbs or other well-defined edges, such edges shall be parallel to the direction of pedestrian flow. The bottom diagonal curb ramps shall have forty-eight (48) inches minimum clear space. If diagonal curb ramps are provided at marked crossings, the forty-eight (48) inch clear space shall be within the markings. If diagonal curb ramps have flared sides, they shall also have at least a 24-inch long segment of straight curb located on each side of the curb ramp and within the marked crossing.
13. 
Curb ramp alignment should be perpendicular to the curb being crossed to provide a level cut for wheelchairs and directional cues for the visually impaired. For large radii, it is often not possible to both, place curb ramps perpendicular to the curb and in-line with the pedestrian crossing. Ramps may be set back from the curb to provide a grade break that is perpendicular to the ramps slope and a landing or blended transition will continue to the curb. If the bottom of the ramp is more than five (5) feet from the curb, detectable warnings are placed at the back of the curbline.

Editor's Note: Former Subsection (B)(4), regarding width of driveway approaches, was repealed 8-22-2022 by Ord. No. 11-2I 171.
5. 
Residential entrances on existing City roads shall be located so the edges of the curb opening shall be a minimum of five (5) feet from the nearest edge of street inlets and ten (10) feet from the street corner radius point. The edges of the curb opening shall not project beyond the side property line extended normal to the pavement.
6. 
In the case of corner lots, no driveways shall be constructed within the sight triangle area bounded by the property lines of a corner lot and a line connecting two (2) points on the property lines each measured thirty (30) feet from the intersection of the two (2) property lines at the intersection. Where applicable, easement lines shall be substituted for property lines.
7. 
The distance between adjacent residential entrances shall be a minimum of twenty (20) feet measured along the road right-of-way line. When residential development conditions necessitate reduction of the distance between adjacent residential entrances to ten (10) feet or less, the City may require a common entrance approach.
8.
