21A-33 Streets and sidewalks | St. John Town Code

Sec. 21A-33. Streets and sidewalks.

(a) Grading. The subdivider shall grade the full width of the right-of-way of all streets proposed to be dedicated in accordance with plans and specifications approved by the Town. The subdivider shall grade the roadbeds in the street right-of-way to subgrade.

The subgrade shall have compaction and/or density tests performed as prescribed in the current edition of Standard Specifications of the Indiana Department of Transportation before the base is constructed. Proof rolling of the subgrade shall be required prior to performing compaction and/or density tests. Where fill is required to bring the subgrade to the proper elevation, the same test is required for each lift. Each lift shall not exceed twelve (12) inches in depth, except in cases where the depth of fill required exceeds four (4) feet. In this case, lifts of twenty-four (24) inches may be permissible if a method of compaction is proven to achieve the minimum density required. The location and number of compaction and/or density tests shall be approved by the Public Works Department and/or Town Engineer. Test results are to be submitted in writing to the Department of Public Works or the Building and Planning Department before the next lift or base is installed. The subgrade shall be compacted to a minimum of ninety-five (95) percent of Standard Proctor for frontage and minor streets. Compaction requirements for collector and arterial streets shall be per the Town Engineer, but in no case less than ninety-five (95) percent of Standard Proctor.

(b) Surfacing. After the installation of all utility and stormwater drainage improvements, the subdivider shall surface all roadways and streets proposed to be dedicated to the widths described by these regulations and the Comprehensive Plan or Comprehensive Plan components of the Town. Said surfacing shall be done in accordance with plans and standard specifications approved by the Town. The intermediate coat of asphalt and curbs must be installed before any building permits are issued. All street construction shall be performed in the manner prescribed in the applicable sections of the current edition of Standard Specifications of the Indiana Department of Transportation, and in the manner prescribed in any subsequent and applicable Town ordinance. In any instance where conflicting requirements may appear between Standard Specifications and an applicable municipal ordinance, the Town Engineer shall make the final determination.

(c) Curb and Gutter. After the installation of all utility and stormwater drainage improvements, the subdivider shall construct concrete curbs and gutters of a roll-type or as otherwise approved. Rebar dowels shall be required at cold joints or across utility trenches.

(1) A concrete sidewalk shall be installed on both sides of all streets within the subdivision unless the Plan Commission rules otherwise.

(2) Wider than standard sidewalks may be required by the Plan Commission in the vicinity of schools, commercial areas and other places of public assemblage and the Plan Commission may require the construction of sidewalks in locations other than required under the preceding provisions of this chapter if such walks are necessary, in their opinion, for safe and adequate pedestrian circulation. Eight (8) foot wide sidewalks shall be required along Town streets with a right-of-way width of eighty (80) feet and above.

(3) Sidewalks shall have curb ramps in line with the sidewalk along the street between blocks that conform with the Americans with Disabilities Act (ADA) at all streets. Cast iron detectable warning mats shall be used at all such curb ramps and shall be painted brick red. The area between sidewalks extended to the curb shall be concrete, not grass or other material that requires maintenance. Such curb area shall not be depressed.
