§ 12.08.040. Pavement preservation.

A.

Excavation of pavement in a street that has a newly placed maintenance course (being defined as a pavement surface course addition less than one inch in thickness) may not be made for two years after substantial completion of the work.

B.

Excavation of pavement in a resurfaced street (being defined as a pavement surface course greater than one inch in thickness up to and not including new construction or reconstruction) may not be made for five years after substantial completion of the work.

C.

Excavation of pavement in a newly constructed street or reconstructed street (being defined as a construction that as a minimum involves the complete removal and replacement of the existing surface course) may not be made for eight years after substantial completion of the work. This shall include newly constructed roads intended for dedication to the city through subdivision or other development activities.

D.

Exception. In the event of an emergency, as determined by the city engineer, excavation may occur upon approval of the replacement limits as follows:

1.

Asphalt Streets.

a.

Restoration will be no less than one lane width and extend no less than three feet in the longitudinal direction from the edge of the cut or greater as required by the city standard specifications. The cut width includes the required ledge to undisturbed soil on both sides of the trench excavation.

b.

A bituminous seal coat of the asphalt pavement will be required for uniformity, or other acceptable method to match pavement color. The determination of treatment type will be made by the city engineer. The treatment shall extend ten feet in each direction beyond the limits of the cut.

2.

Concrete streets.

a.

The removal limit will extend beyond the edge of the cut to the nearest expansion, construction or dummy joint or to the point halfway between the two joints where the edge of the cut terminates, whichever is less, or additional as required by the city standard specifications.

b.

The cut width includes the required ledge to undisturbed soil on both sides of the trench excavation.

E.

Exception. In the event of non-emergency conditions for Section 12.08.040 A. B., and C. (including collector and arterial streets where pavement is older than four years), the petitioner shall have the option to overlay and replace the surface course of the street, which may be up to its entirety to the next construction seam, the limits of which shall be determined by the city engineer.

1.

General guidance for the city engineer shall be:

a.

Trench repair shall be completed per city asphalt or concrete trench repair specifications. The cut width shall include the required ledge to undisturbed soil on both sides of the trench excavation. Each mainline or lateral trench shall be considered a separate trench or excavation activity for testing purposes thereby requiring each separate trench or excavation location to have material and compaction testing provided for each backfill lift in accordance with city specifications and policies.

b.

One year following the excavation, asphalt shall be milled to a depth of one and one-half inches. Asphalt shall extend a minimum of thirty feet in length or five feet beyond the trench length. Width of mill and replacement shall be to centerline of roadway if the trench was only on one half of the street. Width of mill shall be the entire width of the street if the trench crossed the centerline.

c.

Following the mill, the block of street shall be sealed at all crack/joint locations and the length of street extending for the entire block on each side of the mill location shall be sealed with a bituminous seal coat meeting city specifications. The determination of treatment type will be made by the city engineer.

d.

If a roadway cut falls within five feet of the centerline of roadway, the patch must extend the full width of the road

F.

Exception. In the event of non-emergency conditions for Section 12.08.040 C. on collector and arterial streets where pavement is less than four years old, a mill and overlay of the roadway section from nearest intersection to nearest intersection, not more than six hundred sixty linear feet, shall be completed one year following the excavation.

G.

Fees. Excavation and final trench repair shall be guaranteed by a performance guarantee in accordance with Chapter 17.9 of the American Fork City Municipal Code with the city in the minimum amount of two thousand dollars plus five dollars for each square foot of replacement in excess of four hundred square feet or the anticipated roadway repair cost if greater as determined by the city engineer. The fee provision established herein shall increase as updated routinely with other city fees.

H.

Permits. Any person excavating within a public right-of-way, prior to commencement, shall obtain a permit to complete such activities as issued by the city engineer or designee.

I.

Trench repair. Trench repair shall require a pavement restoration in the minimum amount of three inches of asphalt for local streets or five inches of asphalt for collector or arterial streets, with the provision that in all cases trench repair pavement sections shall be one inch in depth in addition to the depth of the existing asphalt on the street being disturbed. Trench repair shall include an additional ledge of undisturbed soil that shall increase in width as the depth increases. For excavations between one and five feet in depth, the ledge shall be between one and two feet. For excavations deeper than five feet, the ledge shall be four feet and shall include a recompaction of the soil within two feet of the surface to the two feet nearest the trench or excavation limits.

J.

Streets improved and dedicated to the city as a part of subdivisions or other land development activities.

1.

Section 12.08.040 C. and E. shall apply to all roadways constructed and/or improved as a part of the development code approval process, which streets are dedicated to the city.

2.

At or near the close of the durability retainer period as defined in Section 17.9.400 of the American Fork City Municipal Code, the following shall be applied:

a.

A bituminous crack seal compound shall be applied to all concrete/asphalt joints and a crack seal to any asphalt cracks that are less than three-eighths inch in width. Any crack in excess of three-eighths inch in width shall require replacement per Section 12.08.040 E.

b.

Following the installation of the crack seal compound, a bituminous seal coat shall be applied over all asphalt surfaces. The determination of treatment type will be made by the city engineer.

c.

These treatments shall be applied prior to the release of the durability retainer. Failure to apply the treatments shall constitute "default" as per Section 17.9.500 of the American Fork City Municipal Code and the durability retainer funds shall be requested from the issuer and used by the city to install the treatments and remedy any other item guaranteed by said durability retainer.
