A. General Requirements:
1. Sidewalks shall be installed on both sides of all public streets and shall run to the back of the curb at each corner lot.
2. All sidewalks along streets shall be installed in the public right of way. The back of the sidewalk shall be one foot (1') inside the right of way, unless, for good cause shown, a variance in location is authorized by the village board of trustees. Sidewalks at the cul-de-sac terminus of dead end streets may be built as close as four feet (4') to the curb with the authorization of the village engineer.
3. The village board of trustees may waive or defer the requirements that the subdivider install sidewalks in all subdivisions except those restricted to multi-family or apartment developments.
4. Public crosswalks shall be located within the ten foot (10') easement or commons area as directed by the village engineer. This location shall be dependent upon the location of proposed utilities within the same easement.
5. All proposed sidewalks abutting streets shall be ramped with a nonslip surface so that the street and sidewalk blend to a common level, enabling persons in wheelchairs to travel freely. See subsection B9 of this section.
6. Sidewalks shall be constructed by the subdivider after site grading but prior to any construction upon any individual lot. The sidewalk adjoining a block of roadway shall be constructed at one time.
7. a. The construction of sidewalks may be deferred until after construction upon any individual lot. In this way, damage may be avoided to previously installed sidewalks during the construction process. Construction of the sidewalks must commence within one year from the date that any other portion of the public improvements are accepted by the village.
b. If construction of the sidewalk or a portion of the sidewalk is deferred until after lot construction, the construction performance guarantee must not be reduced to an amount less than the value of the sidewalks. See subsection 12-4-6D of this title. Maintenance guarantee and surety shall be required after the sidewalks are dedicated to the village. See subsection 12-4-9E of this title.
B. Design:
1. All sidewalks shall be a minimum of four feet (4') in width with a preferred width of five feet (5') in areas zoned residential and a minimum of five feet (5') in width in areas zoned commercial or industrial.
2. All sidewalks shall be a minimum of four inch (4") thick portland cement concrete. All sidewalks through driveways shall be a minimum of six inches (6") thick or of a thickness equal to that of the driveway, whichever is greater.
3. Premolded expansion joints shall be placed at forty eight foot (48') intervals and at all curb intersections or intersections with other permanent structures.
4. All sidewalks shall be hand grooved at least one-half inch (1/2") deep, with a one inch (1") grooving tool, at four foot (4') intervals, and edged with an edging tool.
5. Sidewalks shall be constructed having a longitudinal slope no greater than five percent (5%). Ramps are to be constructed per ADA requirements with a longitudinal slope of no greater than one inch (1") per foot.
6. Sidewalks shall be constructed having a transverse slope toward the street of one-fourth inch (1/4") per foot.
7. The subgrade shall be prepared "properly" so that after compaction it will conform to the alignment, grade and cross section shown on the approved plans. Soft and unstable material that will not compact shall be removed and replaced with material authorized by the village engineer. The entire subgrade shall be compacted to not less than ninety percent (90%) of the standard laboratory density. Topsoil materials shall not be utilized for subgrades.
8. Sidewalks along street pavements shall be constructed with not less than two percent (2%) nor more than fifteen percent (15%) slope between the back of curb and closest edge of the sidewalk. All sidewalks shall be built above the street pavement, unless special circumstances dictate otherwise, as authorized by the village engineer.
9. Sidewalk ramps shall comply with the Illinois department of transportation detail 424001-03 (revised January 1, 2004) and section 12-7-6, figure 11, of this title. This detail requires a twenty four inch (24") wide area adjacent to the street with a pattern of raised truncated domes (detectable warnings). The color of the domes shall be the same contrasting color as required by IDOT, namely federal standard color 30166, brick red.
C. Construction Requirements:
1. All sidewalks shall be constructed in accordance with the provisions of the "Standard Specifications For Road And Bridge Construction", IDOT, latest edition.
2. Portland cement concrete mix design shall be the same as stated in this chapter.
3. Portland cement concrete sidewalks shall be field tested at the rate of two (2) specimens per one thousand two hundred (1,200) linear feet or two (2) specimens per day, whichever is greater, for strength, air content, and slump.
4. Sidewalks shall be provided with a light broom surface finish.
5. Sidewalks shall be properly cured and protected for not less than three (3) days. (Ord. 2007-19, 5-21-2007)
