A public street or streets shall be provided to afford convenient access to all property within the subdivision. Proposed streets shall be connected to existing street systems where possible. Private streets or alleys shall not be permitted.
A. Arterial or collector streets shall have a dedicated street right-of-way of eighty feet. Minor streets and cul-de-sac street rights-of-way shall be sixty feet.
B. Minimum dedicated street right-of-way for a cul-de-sac shall be one hundred twenty feet in diameter.
C. Minimum pavement widths for streets as measured from back of curb to back of curb shall be thirty feet. All developers are required to construct a minimum thirty-foot pavement width unless the project property line is the centerline of the dedicated right-of-way in which case the developer shall construct one-half of the required pavement width. If additional pavement width and/or thicknesses are required, the city will participate in the additional cost.
D. Pavement grades shall be:
1. Minimum 0.50%;
2. Maximum 8.00%.
E. Radii at pavement intersections shall be twenty-five feet measured along the edge of pavement.
F. All cul-de-sacs shall have a minimum pavement radius of fifty feet measured to back of curb.
G. Horizontal curves in streets shall be permitted provided no curve shall be greater than that approved by the city engineer as reasonably safe for traffic at the particular location of the curve.
H. Street jogs with centerline offsets of less than one hundred twenty-five feet shall not be permitted if the same can be reasonably avoided.
I. Proposed streets which are obviously in alignment or continuation of existing streets already named shall bear the name of such existing streets. In no case shall the name for proposed streets duplicate existing names irrespective of the use of the suffix street, avenue, road, boulevard, drive, place, or court, or an abbreviation thereof, or minor variations in spelling.
J. Provisions shall be made to grant access for future development of unplatted adjacent land at intervals of not more than one-quarter mile.
K. Blocks shall not be less than four hundred feet nor more than eight hundred feet in length except as the plan commission considers necessary to secure efficient use of land or desired features of the street pattern. In blocks six hundred feet or more in length, the plan commission may require a public crosswalk for pedestrian travel to extend entirely across the block at the location deemed necessary. The crosswalk shall be constructed of portland cement concrete. The width of the concrete shall be four feet, thickness four inches, and the crosswalk shall be located on a ten-foot easement. Blocks shall be wide enough to allow two tiers of lots, except where fronting on major streets or prevented by topographical conditions or size of the property, in which case the plan commission will approve a single tier of lots.
L. Cul-de-sacs shall have a maximum length of six hundred feet measured from the centerline of the intersection street to the center of the turnaround, unless the topography of the land being subdivided, or the physical situation of that land, makes such a restriction impractical.
M. Where an existing street is adjacent to the subdivision, the subdivider shall improve the half of the street to conform to these standards, except where the existing street is a town-ship road.
N. If any trees are proposed to be planted in any part of the subdivision devoted to public use, the species of trees and the location thereof shall be subject to the approval and direction of the Hoopeston plan commission.
O. Street signs shall be erected at each street intersection within the subdivision. A detail of the street sign is attached to these standards and located at the end of this title. (Standard Drawing No. 1)
P. Before final approval all pavements shall be cored for thickness by the developer in the presence of the city engineer. Two cores shall be taken every five hundred feet per lane unless deficiencies are encountered. Requirements in the event of deficient pavement thickness shall be as follows:
1. One inch or less deficiency will be accepted only in isolated area;
2. Over one inch deficiency will be removed and replaced to the plan thickness or an asphalt overlay constructed as approved by the city engineer.
