(a) The arrangement, character, extent, width, grade and location of all streets shall be considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets.
(b) Conformity to Planned Public Way. Whenever a tract of land included within any proposed subdivision embraces any part of a planned public way, shown on plans which have been adopted by the proper authority, such part of the proposed public way shall be platted by the subdivider in the location and the width indicated by the plan.
(c) Storm Drainage. Adequate storm drainage shall be required, as per standards established by the Department of Public Works and Water Pollution Control. These standards shall control the design and construction of storm drainage facilities so that acceptable storm water flow and minimum acceptable runoff qualities are achieved by the subdivider.
(d) Classification of Streets. Streets which may be classified by definition under two or more street types shall conform to the higher requirements. Marginal access streets shall conform to the regulations for the purpose they serve, i.e., residential street or business street.
(e) Street and Subdivision Names. The proposed name of the subdivision and the proposed street names shall not duplicate or too closely approximate the name of any other subdivision or street in the area covered by this Chapter. Proposed streets which are obviously in alignment with existing streets or are an extension of an existing street shall bear the name of the existing street. All street names shall be subject to approval by the Planning Commission.
(f) Subdivision Containing or Abutting Major Street or Railroad Right of Way.
(1) Where a subdivision abuts or contains an existing or proposed major street, the Planning Commission may require marginal access streets, reverse frontage with screen planting contained in a non-access reservation along the rear property line, deep lots with rear service lanes, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
(2) Where a subdivision borders on or contains a railroad right of way, the Commission may require a street approximately parallel to and on each side of such right of way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential streets, or for the business or industry in the appropriate districts; such distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
(g) Half Streets. Streets within a proposed subdivision shall be designed where possible to allow for a through connection to a future subdivision on adjacent property or to future phases of the same subdivision. These shall be known as half streets and shall be designed with temporary T-turnarounds at their ends. The turnaround shall be removed and a permanent through street created when the adjoining property is subdivided and where a half street is contiguous to a previously platted half street. Half streets shall be shown on the final plat.
(h) Street Center Line Offsets. Street jogs with center-line offsets of less than 125 feet shall not be allowed.
(i) Tangents Between Reverse Curves. A tangent at least 100 feet shall be introduced between reverse curves on major and collector streets.
(j) Street Intersections
(1) Three-way street intersections should be utilized, using four-way intersections only when absolutely necessary.
(2) Flat grade within and fifty to one hundred feet each way from the street intersection is preferred but over seven percent (7%) grade is not acceptable.
(3) Right angle street intersections are preferred, but no intersection shall be at an angle of less than seventy-five degrees or more than one hundred fifteen degrees. The curb radius for residential and commercial streets shall be twenty feet. The curb radius for a collector street intersecting a major street shall be fifty feet.
(4) A clear sight triangle shall be provided at all street intersections. Within such triangle no vision-obstructing objects shall be permitted which exceed a height of twenty-four inches above the elevation of the abutting streets.
(5) Such sight triangles shall be established from a distance of:
A. One hundred feet from point of intersection of the street center lines for major streets;
B. Seventy-five feet from point of intersection of the street center lines for collector streets;
C. Fifty feet from the point of intersection of the street center lines for all other streets.
(k) Residential Streets to Discourage Through Traffic. Residential streets shall be so laid out that their use by through traffic will be discouraged.
(l) Street Grading. All streets shall be graded to their full right-of-way width so as to provide adequate shoulders and pedestrian walkways. All streets shall be paved, and drainage courses, sidewalks and other structures installed according to City standards. Driveways shall meet the sidewalk grade at the property line.
(m) Street Installation Responsibility. The subdivider shall be responsible for the cost and installation of the road foundation and paving necessary to meet the requirements of this Chapter.
