(B) Street cross-section standards.
(1) Major thoroughfares. Cross-sections in accordance in conformance with the specifications of the County Road Commission.
(2) Local streets. To be determined.
(3) Minor streets. Sixty-foot right-of-way. A four-foot concrete sidewalk located one foot from the property line on each side of the roadway shall be provided.

(D) Grading and centerline gradients. Per plans and profiles approved by the village.
(E) Street grades. For adequate drainage, the minimum street grade shall not be less than 0.4%. The maximum street grade shall be 6%.
(F) Alignment.
(1) Vertical curves shall be adequate to provide the minimum vertical visibility as required under division (F)(3) below for major thoroughfares, local streets, and minor streets.
(2) Minimum horizontal curbs - the radii of centerline curvature:
(a) Major thoroughfare: 475-foot radius;
(b) Secondary streets: 300-foot radius; and
(c) A minimum 50-foot tangent shall be introduced between reverse curves on minor streets, 100 feet on secondary streets, and 300 feet on major thoroughfares.
(3) Visibility requirements are as follows.
(a) Minimum vertical visibility (measured from four and one-half foot eye level to 18 inch tail light) shall be: 500 feet on major thoroughfares; 300 feet on local thoroughfares; 200 feet on minor streets; and 100 feet on minor streets less than 500 feet in length.
(b) Minimum horizontal visibility shall be: 300 feet on major thoroughfares, measured on centerline; 200 feet on secondary streets, measured on centerline; and 100 feet on minor streets, measured on centerline.
(4) Streets shall be laid out so as to intersect as nearly as possible to 90 degrees.
(5) Street jogs with centerline offsets of less than 125 feet shall be avoided.

(G) Storm drainage system.
(1) Together with other drainage improvements per plans approved by the Village Council.
(2) Storm sewers shall not be less than 12 inch diameter and laid at such a grade that the flow will exceed two and one-half feet per second when flowing full. Design criteria shall be based on a five-year storm rate. Generally, all storm sewers shall be located 12 feet north or west of the property line.
(3) Stormwater shall run no more than 500 feet before being picked up by a catch basin. If stormwater is carried around an intersection radius, limit of pickup shall be 300 feet if grade is 0.60% or less; if greater than 0.60%, intercepting basins shall be installed.
(4) Adequate provision shall be made for proper drainage of stormwater run-off from residential rear yards. Unless each yard is drained from rear to front, there shall be one rear yard catch basin every 240 feet or less along the rear easement line. Rear yards shall slope at a minimum grade of 0.5% to the proper stormwater catch basin. Rear yard catch basins shall be connected to the stormwater system with a pipe of not less than six-inch diameter with slip seal joints or equal.

(H) Sewage disposal.
(1) The sewage system shall be located within street rights-of-way per plans approved by the City Engineer. Sanitary sewers shall be of not less than eight-inch diameter and tested in accordance with ASTM procedure. Exfiltration tests shall not exceed 750 gallons per inch diameter per mile per day. All sanitary sewers shall be laid at a grade to exceed a flow of two feet per second when flowing full. Minimum sanitary sewer depth in all new work shall be seven and one-half feet below the center of the closest road. Generally, all sanitary sewers shall be located on the centerline on minor streets.
