VILLAGE OF CENTERVILLE GENERAL STREET CONSTRUCTION SPECIFICATIONS 1. GENERAL CONSTRUCTION SPECIFICATIONS The following specifications are general and will apply to each and every street hereafter constructed in the Village. Definite and detailed speci- fications and plans shall be designed by the Village Engineer for each individual project based upon its own location and special features. The detailed speci- fications shall be in accordance with this general outline and for the purpose of residential street construction. All Village streets, including residential access streets, shall be designed as minimum 5 ton (axle loading ) all weather streets capable of handling a minimum of 400 vehicles per day. 2. RIGHT -OF -WAY All streets constructed shall be constructed on right -of -ways of not less than 60 feet in width, except primary streets shall be constructed on right - of -ways of such additional width as may be necessary to accommodate the final completed ultimate street as required by the ultimate use for which that street is designed. 3. TEST The Council may authorize the engineer to conduct such tests, take such borings or make such surveys as may be necessary for the proper design of the street. The cost of such test borings and /or surveys shall be considered as part of the overall cost of the street improvements. 4. GRADING All streets shall be graded for the full width of the right -of -way in accordance with the designed typical cross sections prepared and staked by the Village Engineer. After rough grading has been accomplished and the street is at the approximate designed grade for the full width of the right -of -way, the center 32 feet lying 16 feet on each side of centerline shall be undercut to an elevation which is twelve (12) inches below the established profile grade, or to a depth adequate to accommodate the sub -base, base and bituminous surfacing. 5. SUB GRADE The sub -grade of the streets shall be so constructed as to satisfact- orily sustain the street in a stable condition. Any unsuitable or undesirable material shall be removed. 6. SUB -BASE AND BASE All streets shall be constructed having a gravel sub -base of six inch minimum thickness using gravel conforming to MHD Spec. No. 3138 Class 4, and a gravel base of three inch minimum thickness using gravel conforming to M.H.D. Spec. No. 3138, Class 5. The total minimum thickness of the sub -base and base as mentioned above, are applicable . to the A -6 sub -grade soil group. For other soil groups the following factors shall be employed to determine the total minimum thickness of the sub -base and base. Adjustment of the total thickness shall be made in sub -base only and the three inch minimum thickness of the base shall not be decreased.
