AN ORDINANCE AMENDING JONESBORO CODE OF ORDINANCES CHAPTER 9.08, KNOWN AS EXCAVATIONS AND ALTERATIONS, BY AMENDING SECTION 9.08.03, EXCAVATIONS TO BE RESTORED, AND ADDING SECTION 9.08.04 LIMITS OF EXCAVATIONS.
body
BE IT ENACTED AND ORDAINED, by the Jonesboro City Council that Chapter 9.08, known as Excavations and Alterations be amended as follows:
SECTION 1: 9.08.03 Excavations to be Restored. All material excavated for the street cut shall be removed and disposed of by the person, firm, or corporation performing said excavation. All excavations shall be restored with flowable fill to within 2" of the surrounding bituminous riding surface.
* The mix design for the flowable fill will be prepared by the Applicant. The mixture will be proportioned to produce a flowable mixture without segregation, material for one cubic yard, absolute volume, shall be as follows:
Cement - 80 - 100 lbs.
Fly Ash - 220 - 300 lbs.
Sand - Variable to equal 1 cubic yard Water - Approximately 65 gallons
The minimum flow shall be 8". The unit weight shall be a minimum of 110 lbs./cu. ft.
*If the surrounding riding surface is concrete, flowable fill shall be placed to within 6" of the riding surface.
The flow test shall consist of filling a 3" diameter x 6" high open-ended cylinder to the top with the flowable material mixture. If necessary, the top of the mixture will be struck off level. The cylinder will then be pulled straight up and the flow will be measured by the approximate diameter of the mixture.
Placing of either bituminous hot mix for asphalt surfaces or concrete for concrete surfaces over the flowable fill may begin after the flowable material has taken its initial set, is stable, and does not displace under equipment. A tack coat of liquid asphalt shall be applied to the cut face of the surrounding asphalt pavement before final hot mix surface is placed. Steel plates shall be used to maintain traffic over cuts before flowable fill is placed if necessary and also during the curing time of the flowable fill. These steel plates shall be provided by the City. All pavement restoration shall be made by the City of Jonesboro.
In the event a cut is to be restored during a time when hot asphalt plant mix is not available, cold plant mix may be used as a temporary surface until a time hot plant mix is available. It shall be the applicants responsibility to maintain the cold mix patch until replaced with hot plant mix. The initial deposit will not be released until hot plant mix is in place and a final inspection has been made.
SECTION 2: 9.08.04 Limits of Excavations. The limits of cuts to be restored shall as follows:
(1) All longitudinal cuts within 5' of the edge of the paved surface.
(2) All transverse cuts to a distance of 3' beyond the edge of a paved surface.
When the excavation is not within a gravel surface or concrete or bituminous surface the flowable fill shall be placed to within 6" of the surrounding ground. The remaining 6" shall be filled with topsoil and seeded. The deposit shall be assessed at the rate for gravel surface as indicated in 9.08.02. When a proper stand of grass is obtained the deposit may be released. No cuts shall be made within 200' of a signalized intersection until the Engineering Department has been notified to locate traffic detection loops.
PASSED AND ADOPTED THIS the 15th day of June, 1998.
