The permittee must repair the area affected by the disruption of the street surface and subsurface to a condition equal to or better than the surrounding street surface and maintain the area affected by the disruption until such time as the street, sidewalk or other area is either rebuilt or overlaid. The permittee must further repair or remove and replace any street or other surface scarred by work performed pursuant to this section. All repairs shall be inspected and approved by the superintendent of streets upon completion. If a repair is not approved by the superintendent of streets, it must be repaired again to meet approval.

A. If the excavation is less than ten feet (10') deep from the existing ground level to the bottom of the excavation, the restoration or repair shall be made as follows:
1. All street openings that are to be repaired in the area of an existing pavement subgrade or where the inner edge of a trench for such conduits of closer than two feet (2') to the edge of the existing pavement, stabilized shoulder, curb, gutter or sidewalk shall be backfilled with the following materials:
a. All trenches, structures, culverts, utility cuts and other work extending under pavement locations shall be filled with control low strength material (CLSM). No material excavated may be placed back in the excavation.
b. CLSM shall consist of one of the following mixtures:
MIXTURE NO. 1
Portland cement | 50 | pounds |
Fly ash | 200 | pounds |
Fine aggregate (SSD saturated surface dry) | 2,990 | pounds |
Water | 49 - 57 | gallons |
(Ord. 575, 3-27-2000)
MIXTURE NO. 2
Portland cement | 185 | pounds |
Fine aggregate (SSD) | 2,990 | pounds (SSD) |
Air-entraining admixture | 6 | fluid ounces |
Water | 49 - 57 | gallons (as directed) |
These quantities will give an approximate yield of one cubic yard. The flow ability of the mixture shall be observed by the street superintendent or his/her designee and the water content increased/decreased within the stated limits for mixture no. 1 and the water content and the air-entraining admixture content increased/decreased as directed for mixture no. 2.
The mixing of the CLSM shall be as specified in section 803 of the "Standard Specifications For Road And Bridge Construction" adopted July 1994, by the Illinois department of transportation or as approved by the street superintendent.
c. All materials incorporated shall meet all requirements of the "Standard Specifications For Road And Bridge Construction" adopted July 1994, and more specifically the following or as approved by the street superintendent or his/her designee:
Water | 702 |
Fine aggregate | 703 ASTM C 33 |
Portland cement (type 1) | 718.19 (b) |
Fly ash (class C) | 701 |
Air-entraining admixtures | 718.01 (b) |
d. The CLSM must be free of frost prior to placement of any surface. (Ord. 550, 2-22-1999)
2. Areas that have been opened in existing pavement to facilitate the installation or repair of utilities shall be saw cut to provide a square edge with the existing pavement. All holes shall be temporarily patched with a minimum of six inches (6") of bituminous cold patch mixture or shall be permanently patched as set forth below.
A permanent patch shall be constructed by October 15 following the installation of the temporary patch in the following manner: a) if concrete, the same thickness of concrete as the existing pavement, but not less than six inches (6") of PCC concrete; b) if bituminous surface, three inches (3") of bituminous cap and six inches (6") of PCC concrete base, or if the pavement is full depth bituminous eight inches (8") or greater, then bituminous of the same thickness as the existing bituminous. (Ord. 636, 5-13-2002)
B. If the excavation is greater than ten feet (10') deep from the existing ground level to the bottom of the excavation, the restoration or repair may be made as provided in subsection A of this section, or shall be made as follows:
1. All street openings that are to be repaired in the area of an existing pavement subgrade or where the inner edge of a trench for such conduits is closer than two feet (2') to the edge of the existing pavement, stabilized shoulder, curb, gutter or sidewalk shall be backfilled with the following materials:
The top ten feet (10') shall comply with the CLSM requirements as provided in subsection A of this section. Below the initial ten feet (10') of CLSM, selected granular backfill materials for the repair of said openings shall consist only of sand, stone sand, crushed stone, or crushed gravel with gradations as specified in 20-2, 21C of the said standard specifications. This backfill material is to be placed and compacted in lifts not to exceed eighteen inches (18") and placed to within six inches (6") of the finished surface. (Ord. 575, 3-27-2000)
2. Areas that have been opened in existing pavement to facilitate the installation or repair of utilities shall be saw cut to provide a square edge with the existing pavement. All holes shall be temporarily patched with a minimum of six inches (6") of bituminous cold patch mixture or shall be permanently patched as set forth below.
A permanent patch shall be constructed by October 15 following the installation of the temporary patch in the following manner: a) if concrete, the same thickness of concrete as the existing pavement, but not less than six inches (6") of PCC concrete; b) if bituminous surface, three inches (3") of bituminous cap and six inches (6") of PCC concrete base, or if the pavement is full depth bituminous eight inches (8") or greater, then bituminous of the same thickness as the existing bituminous. (Ord. 636, 5-13-2002)
3. The material for granular cradle for restoration of streets opened for the repair or installation of sanitary sewer, storm sewers or water distribution shall be stone, screening, crushed stone, pit run gravel, washed gravel, crushed boiler slag, or other granular material approved by the city or its representative and conform to gradations specified in said standard specifications. (Ord. 575, 3-27-2000)
C. If the permittee fails to repair in accordance with this section or section 9-1-9 of this chapter, after notification by the superintendent of streets, then the city may, at its option, repair or replace such portion of the street, sidewalk or other area and the permittee shall be liable for the city's reasonable costs, including labor, engineering and attorney fees.
