(d)

Where conflict arises between GDOT standards and this section concerning non-local roadways, the stricter standard shall apply. Design of local roadways shall be governed by the policies as stated within the UDO; however, construction methods/practices of said roadways shall be governed by the stricter of the GDOT standards and the UDO.

(e)

All materials, equipment, labor and other matters related to street construction shall be provided by the applicant. The following is a summary of the improvements required:

(1)

All streets, roads, and alleys shall be graded to their full width right-of-way by the applicant so that the pavements and sidewalks, when installed in the future, can be constructed on the same level plane. The preparation of the right-of-way before grading is started, and the construction of cuts and fills, shall be accomplished according to the specifications of the county (see subsections 6.01.07(i) and (k)).

(2)

Two copies of an as-built subgrade centerline profile shall be submitted to the county. The profile shall include both proposed and as-built centerline elevations at every even station. No curb and gutter or waterlines shall be installed prior to subgrade approval.

(3)

An adequate drainage system, including necessary curbs, pipes, culverts, headwalls, intersectional drains, drop inlets, bridges, swale ditches, and detention areas, shall be provided for the proper drainage of all surface water. The drainage system shall be designed by a registered professional engineer, licensed in the state of Georgia.

(4)

After preparation of the subgrade, the roadbed shall have base material and paving applied according to county specifications (see subsections 6.01.07(i) and (k)).

(f)

Installation of underground public utility lines. The following minimum specifications shall govern the installation of underground public utility lines on county road rights-of-way.

(2)

Public utility lines shall be located underground along all new roads, and, at the discretion of the public works director, on all existing roads when serving new construction, excluding single-lot residential development.

(3)

Paved roads shall be bored rather than cut for the installation of utilities. The cutting of all paved county roads shall require the approval of the public works director prior to the cut being made.

(4)

Any paved road which is saw cut to a width of more than 12 inches shall be filled with a compacted base material to within eight inches of the riding surface and with concrete to within two inches of the riding surface. The remaining two inches shall be filled with asphaltic concrete to allow for a smooth riding surface.

(5)

Any paved road which is saw cut to a width of 12 inches or less shall be filled with a compacted base material to within two inches of the riding surface. The remaining two inches shall be filled with asphaltic concrete to allow for a smooth riding surface.

(6)

Any dirt road which is cut shall be filled with a compacted base material.

Private roads may be allowed only by authorization from the board of commissioners. Any such roads must be designed and constructed in accordance with all applicable county ordinances and specifications. Verification must be provided by the owner/developer at their own expense to satisfy the county engineer.

(a)

New roads. Prior to new roads being accepted into the county road system by the board of commissioners, the proposed road name shall be reviewed and approved by the county's technical review committee, which shall be a standing committee of the county department heads or their representative and be chaired by the director of the Butts County EMA-911, to ensure that the road name will not cause confusion with other roads. Roads that are obviously in alignment with roads within the same subdivision development should be given the same name. The names of new roads should not duplicate or closely approximate those of the existing roads in the county.

(b)

Name changes. Before the name of any county road may be changed from the current official name, the request shall be presented to the county's technical review committee to ensure that the proposed name will not cause confusion with other roads. If the proposed name is approved by the technical review committee, then the board of commissioners shall hold a public hearing for determination of whether to change the road name. A notice shall be published in the legal organ of the county once a week for three weeks stating the name of the road to be changed, the general location of the road, the proposed new name and the date, time and location of the hearing. The cost of the advertising shall be paid by the proponents of the name change.

(a)

Purpose. This section is enacted to more efficiently provide for the safety of persons and vehicles traveling on the county roads of Butts County, as allowed under O.C.G.A. § 32-4-42(6).

(1)

When the board of commissioners reasonably determines that any pipe, main, conduit, cable, wire, pole, tower or other signal and equipment, facilities or appliances of any utility in, on, along, over or under the public roads of the county should be removed or relocated because it has become an obstruction or interference with the use and safe operation of a county road, or will become an obstruction or interference with the use and safe operation of a contemplated county road or project, a written notice shall be directed to the utility company, giving at least 60 days notice in which to make such change as is necessary for removal or relocation as may be necessary.

(2)

If the utility does not thereafter begin removal within a reasonable time sufficient to allow for engineering and other procedures reasonably necessary to the removal and relocation of the utility facility, the board of commissioners may give the utility a final notice directing that such removal shall commence not later than ten days from receipt of such final notice.

(3)

If such removal has not begun, or if such removal has begun and the relocation has not been completed within a reasonable time, the county may remove or relocate the same with its own employees, or by contracted labor, tools, equipment, supervision or other necessary services or materials and whatever else is necessary to accomplish the removal or relocation, and the expense thereof shall be charged to the utility.

(4)

Such expense shall be certified to the county attorney, who shall have the authority to proceed with suit against the utility for same if payment or arrangements to make payment are not made within 60 days.

(5)

A copy of the delivery tickets for the asphaltic concrete material used shall be furnished to the division director or designee at the time of completion of the work. If the delivery tickets indicate a shortage in the material used from the quantity estimated, the division director or designee may require a minimum one-inch overlay of the streets.

(6)

As mentioned in subsection 6.01.07(d)(4), the GAB (base) thickness is to be measured and accepted by the county prior to placement of any asphalt course. The applicant shall have core tests made to verify the thickness and compaction of the asphalt pavement course. The minimum core diameter shall be such that compaction of the sample can be determined in the lab and subsequent data supplied to the division director or designee. The compaction of the course shall be required to meet GDOT specifications per the asphalt mix placed. If a two-course asphalt section is required, the cores for the binder layer shall be cut, reviewed, and approved by the division director or designee prior to placement of the topping lift. Also, in the event that a two-course asphalt section is required, the cores for the topping lift, if between one and one-half inch and one and one-quarter inch in thickness, shall be made to determine the thickness only. All cores shall be made on 400 feet intervals, alternating between each lane and center of roadway. If these cores indicate a deficiency in thickness or compaction of the asphalt pavement, an overlay shall be required when the following deficiencies occur:

a.

When the number of cores deficient in thickness within the allowable one-quarter of an inch tolerance, or deficient in compaction, exceeds 35 percent of the total cores taken on one street.

b.

When two or more consecutive tests show a deficiency of more than one-quarter of an inch allowable tolerance or a deficiency in compaction. When a core shows a deficiency in excess of the allowable tolerance or compaction, additional cores shall be taken to delineate the area of the deficient thickness/compaction.

(7)

The applicant shall correct any deficiency with an overlay extending a minimum of 150 feet beyond the outer limits of the deficient area for the full width of the street. Smooth, neat joints shall be saw cut normal to the roadway for full depth of asphalt pavement, removing the original pavement for a minimum of ten feet at each end of the overlay.

Table 6.04.01. Allowable Pipe Use

Notes:

1) All pipe materials shall meet the minimum requirements of the Georgia Department of Transportation's Standard Specifications Construction of Transportation Systems, most current edition.

2) Allow smoothed-lined HDPE, Type S (AASHTO M294) pipe for storm (longitudinal and cross) and side drain applications through 48-inch diameter so long as roadway's ADT is less than 15,000 vehicles per day.

(d)

Backfilling. Backfill for CSP, CAP, and HDPE pipe installations shall be constructed using graded aggregate base or crusher run six inches below the bottom of pipe to 12 inches above the pipe crown. Backfill for RCP pipe installations shall be constructed using graded aggregate base or crusher run six inches below the pipe invert to one-quarter of the pipe diameter. Foundation backfill material shall be used for RCP above one-quarter of the pipe diameter (if graded aggregate base is not used above one-quarter of the pipe diameter) as per Type I or Type II, as specified in sections 812.01 and 812.02 respectively, in Georgia DOT Standard Specifications. These materials shall be placed in layers of not more than six inches loose. Compaction of these materials shall be accomplished by hand tamping or machine tamping. Required compaction levels are as follows:

(1)

Within street right-of-way. Backfill within all street rights-of-way shall be compacted to 95 percent maximum density, tested using the AASHTO Method T-99.

(2)

In other areas. Backfill in all other areas shall be compacted to 90 percent maximum density, tested using the AASHTO Method T-99.

(3)

Construction loads and minimum covers. If drainage pipe is installed prior to the completion of grading, a minimum of four feet of fill should be provided where needed to adequately protect the drainage structure during the land development phase, unless the structure itself is designed to withstand the anticipated live load during construction.

(e)

End finish.

(1)

Headwalls or other end treatments are required on all culverts and at the outlet of all piped collection systems. Where ends of pipe are located within, or near, the right-of-way and are parallel, or nearly parallel, with the roadway, safety end sections shall be required when the posted speed limit is 35 miles per hour and over.

(2)

Headwalls are to be precast concrete, stone masonry with reinforced concrete footings, or poured in place, reinforced concrete with reinforced concrete footings. Precast concrete headwalls for corrugated aluminum coated steel pipe or aluminum alloy pipe shall be made with aluminum coated steel or aluminum alloy pipe stubs.

(3)

End treatments that conform to the slope may be pre-cast concrete end sections, aluminum coated steel or aluminum alloy end sections, masonry, PE end sections, reinforced poured-in-place slope collars, or grouted rip-rap. Concrete and metal flared end sections shall conform to applicable Georgia DOT Standard Drawing 1120, 1122, or Detail D-39.

(f)

Junction boxes and catch basins. Junction boxes and catch basins shall have metal manhole frames and lids for access.

(g)

Other structures. Natural bottom arches and box culverts may be used in accordance with the latest standard specifications of the Georgia Department of Transportation. Bottomless culverts shall require that a scour analysis be done by a registered professional engineer in that field to Georgia Department of Transportation Specifications and Standards to ensure the soundness of the proposed structure.

(a)

Each site requiring a driveway pipe/culvert for access shall be analyzed for stormwater runoff flow patterns and sized for a minimum 25-year storm event by the design professional.

(b)

Where a driveway pipe will be used in a stream crossing, the pipe shall be sized for a 100-year storm event by the design professional.

(c)

The construction plans and the final plat shall show the minimum driveway pipe size required for each lot.
