A. Streets (and alleys, where provided) shall be completed to grades shown on plans, profiles, and cross-sections provided by the subdivider and prepared by a registered professional engineer and approved by the Commission.
B. The streets shall be graded, surfaced, and improved to the dimensions required by the cross sections and the work shall be performed in the manner prescribed in "Standard Specifications for the Indiana Department of Highways," latest issue hereinafter referred to as the Standard Specifications. A copy of the current Standard Specifications should be on file in the office of the Zoning Administrator.
C. The following are describe the different roadway classifications:
1. Highways are devoted to high-speed, long distance traffic movement with (ideally) little or no access to adjacent land. Highways typically carry over 20,000 trips per day.
2. Arterials move traffic between principal traffic generators. Direct residential access is generally discouraged, but access to commercial or industrial areas is allowed. Arterials generally carry 5,000 to 20,000 trips per day.
3. Collectors serve internal traffic functions, and generally function to connect local streets (below) to arterials. They can also provide direct access to property. Collectors typically carry 1,000 to 1,500 trips per day.
4. Local streets exist primarily to provide access to adjacent land.
D. Local streets shall be surfaced to a minimum width of thirty (30) feet, measured back to back of curb. Streets classified in the Thoroughfare Plan shall be surfaced to a minimum width of forty-two (42) feet.
(Curb and gutter is included in the minimum surface, see division (I) herein.) The Commission may require the subdivider to provide street surfacing on streets which are proposed to be extensions of existing paved streets, and which exceed the minimum dimensions set forth above, to the full width of the existing paved street. Alleys shall be surfaced to their full width. Cul-de-sac turn-arounds shall be paved to a diameter of seventy-six (76) feet.
E. The streets shall be graded, surfaced and improved to the dimensions required by the cross sections and the work shall be performed in the manner prescribed in "Standard Specifications for the Indiana Department of Transportation," latest issues (hereinafter referred to as the Standard Specifications). A copy of the current Standard Specifications is available through the Town Engineer.
F. The subgrade shall be prepared in compliance with Section 207 of the Standard Specifications.
G. The subbase, where required, shall be prepared in compliance with Section 304 of the Standard Specifications. Special subbase drainage in areas of cuts, swales, and fills shall be as set out in the approved plans and specifications.
H. The street surface shall be of Portland Cement Concrete materials and construction shall be in accordance with Section 501 of the Standard Specifications and division (1) below. Hot asphalt concrete materials and construction shall be in accordance with Section 403 of the Standard Specifications and division (2) below. In the case of a proposed alternative method, discrepancy, omission or duplication in the required specification standards, the decision of the Town Board shall be sought and considered final.
1. Rigid Type Pavement (Portland Cement Concrete).
a. Minimum design characteristics of street pavement shall be as follows:
1. 6% air entrained.
2. 28-day compressive strength 4000 p.s.i., 28-day flexural strength 550 p.s.i.
3. Thickness shall conform to the following schedule:
Residential | Collector/Feeder | Arterial | |
Concrete | 6" | 7" | 8" |
Aggregate | Subject to review by Town Board | 4" | 4" |
Subbase | Subject to review by Town Board | 4" | 4" |
b. Portland Cement Concrete pavement shall be in accordance with Section 501 of the Standard Specifications. In addition, the following shall govern and be met:
1. The subgrade shall conform to Section 501.5 and 207 of the Standard Specifications. Subgrade shall be moist but not muddy at the time the concrete is placed. If required, it shall be sprinkled, but the method of sprinkling shall be such that mud or pools of water will not be formed.
2. Subbase, if required, shall meet the above minimum thickness requirements and conform to Section 304 of the Standard Specifications.
3. Weakened plane or dummy transverse contraction joints shall be placed not to exceed twenty (20) foot spacing. A transverse contraction joint shall be placed at every catch basin and manhole in line of pavement. The location of manholes, and the like, in the pavement shall determine the exact location of joints. All joints must extend throughout sidestrips to full width of pavements. Transverse contraction joints will be a groove and conform to Section 504.14 of the Standard Specifications.
4. Whenever the width between forms of the pavement under construction is greater than thirteen (13) feet, longitudinal joints shall be constructed so as to divide the pavement into strips not to exceed thirteen (13) feet each. Work shall conform to Section 504.14 of the Standard Specifications.
5. Expansion joints, with approved dowel bar assembly, shall be placed at intersections where shown on the plans and shall conform to Section 501.15 of the Standard Specifications.
6. Concrete shall be machine finished except on widened portions, intersections, or other places where hand finishing will be permitted if authorized. Finishing machines or vibrating strike-boards of design other than as specified in the Standard Specifications will be permitted only if work of equal quality as set out in these specifications is obtained. Authorization prior to construction is required. Work shall conform to Section 501.15 of the Standard Specifications.
7. Curing with approved impervious membrane or sealing compounds shall be required, conforming to Section 501.17 of the Standard Specifications.
2. Hot Asphalt Concrete Pavement.

Base/Subbase Courses | Local/Residential | Minor/Major Collector | Minor/Major Arterial |
Base | 6" Compacted #53 Stone | 6" Compacted #53 Stone | 6" Compacted #53 Stone |

1. The subgrade shall conform to Section 207 and 215 of the Standard Specifications.
2. Subbase shall meet the minimum thickness requirements and conform to Section 301 of the Standard Specifications.
3. (HMA), base, binder and surface coarses shall meet the above minimum thickness requirements and conform to Section 402 of the Standard Specifications.
