(a) Construction Standards. A concrete sidewalk shall be installed on both sides of all streets within the subdivision. The construction of all sidewalks shall be in accordance with plans and standard specifications approved by the Town and shall be installed prior to the issuance of an occupancy permit, to be five (5) feet wide, four (4) inches thick and expansion joints at a minimum spacing of twenty (20) feet and grooved at a maximum of every five (5) feet with a four (4) inch thick gravel base. The sidewalks across driveways and at street corners shall be six (6) inches thick and shall have welded wire fabric or fiber mesh reinforcing. The sidewalks shall be aligned with the sidewalk across the street and shall have handicapped accessible curb ramps at each street corner or where the Plan Commission deems them necessary. The subdivider shall further be required to construct all sidewalks in conformance with applicable State and Federal building codes and regulations as amended from time to time, as well as the Americans with Disabilities Act (ADA), as amended from time to time. Cast iron detectable warning mats shall be used at all such curb ramps and shall be painted brick red. Concrete used for sidewalks to be the same as concrete used for curbs and gutters. Three (3) separate ten (10) foot lengths of #5 rebar shall be required in sidewalks where there are b-box and sewer tap trenches crossing under the sidewalk section(s) from the street toward the buildings. The rebar shall be centered over the trench and evenly spaced across the width of the sidewalk.

(b) Payment in Lieu of Installation. In extraordinary circumstances, the Plan Commission may determine that the installation of sidewalks is impossible or illogical within the proposed subdivision or amendment and/or replat of subdivision. If the Plan Commission makes this determination, as an alternative to providing sidewalks, a subdivider may make payment to the Town of St. John sidewalk, curb and gutter installation fund in an amount equal to ninety (90) percent of the total cost of the installation of sidewalks. The payment in lieu of installing sidewalks shall be computed on the basis of the current average cost per square foot of sidewalk required, as determined by the Town Engineer. A subdivider's payment to the Town of St. John sidewalk, curb and gutter installation fund under this section does not obligate the Town to install sidewalks at any time on the subdivider's property. The subdivider's payment to the Town of St. John sidewalk, curb and gutter installation fund may be used to install sidewalks anywhere in the Town. Payment in lieu of installation of sidewalks shall release the subdivider from the responsibility to install sidewalks at the present time or any time in the future in those specific areas and locations identified by the Plan Commission. If the Plan Commission determines that the installation of sidewalks is impossible or illogical and the subdivider instead makes payment to the Town of St. John sidewalk, curb and gutter installation fund, this information shall be included in writing on the recorded plat of the subdivision.
