§ 281-46. Resurfacing of street openings.

A. 

Temporary resurfacing.

(1) 

Immediately after backfilling the excavation, the permittee shall place thereon an acceptable temporary resurfacing as provided hereinbelow. Such temporary resurfacing shall be maintained even with the roadway or other surface, as directed, until permanent restoration of the surface is ordered by the Commissioner.

(2) 

The temporary resurfacing shall consist of not less than two inches of approved premixed bituminous paving material except that, where topsoil, seeded areas or sod have been disturbed by the excavation, or by any work related thereto, the permittee shall restore the entire ground area to the same condition as existed before the work began.

(3) 

The permittee is responsible for maintaining the temporary resurfacing in such a manner as to avoid creating a hazard to the vehicular or pedestrian traffic.

(4) 

Permanent restoration of the surface over a street opening excavation shall not be made until satisfactory settlement of the backfill has taken place, in the opinion of the Commissioner.

B. 

Concrete pavements.

(1) 

Before proceeding with pavement resurfacing, the existing concrete pavement shall be neatly cut back a distance of not less than 12 inches beyond the edges of the excavation, care being taken not to remove any existing steel reinforcement. Such distance shall not be reduced without prior approval of the Commissioner and may be increased as provided hereinunder.

(2) 

Where the existing pavement has been undermined by the excavation or by any work connected therewith, or where spalled or scaled surface areas of existing pavement adjoin the area to be resurfaced, the permittee shall remove additional pavement beyond the distance stated hereinabove, as ordered by the Commissioner.

(3) 

In the event that any portion of the proposed concrete resurfacing, as finally determined by the Commissioner as provided hereinabove, is nearer than four feet from a joint, then such removal shall be extended to said joint. The smallest horizontal dimension of the concrete resurfacing shall be not less than four feet.

(4) 

None of the subgrade so exposed shall be disturbed in any way except when, in the opinion of the Commissioner, such subgrade is unstable, in which case the unstable material shall be removed as ordered, and replaced with approved stable material in layers not to exceed four inches, each layer being thoroughly compacted.

(5) 

The upper edges of the existing concrete pavement shall be uniformly plumbed and tooled for a depth not to exceed one inch, the remaining depth being left with straight but rough edges.

(6) 

Reinforcement, consisting of six-by-six-inch, 6/6, welded wire fabric shall be placed two inches above the subgrade and shall be adequately tied in with the existing reinforcement, if any.

(7) 

The edges of the existing concrete payment shall be thoroughly washed, wire brushed, dampened and painted with a neat cement coating of 1:1 immediately previous to the placing of the new concrete resurfacing.

(8) 

The concrete shall be proportioned, mixed, placed, finished and cured as ordered. The Commissioner's may, in the latter's discretion, require the use of an approved high early-strength cement placed under approved methods. The use of admixtures and work in freezing weather will be allowed only with the Commissioner's prior approval and as directed.

(9) 

Approved joints shall be installed where directed.

(10) 

The resurfaced area shall not be opened to traffic until so ordered by the Commissioner.

C. 

Asphalt concrete.

(1) 

Asphalt concrete surface on existing concrete base.

(a) 

Prior to the replacement of the asphalt concrete surface, the subgrades shall be properly prepared and a reinforced concrete foundation of required thickness and proportions shall be placed thereon, all in accordance with the requirements of concrete pavements outlined before.

(b) 

The existing asphalt concrete pavement shall then be neatly cut back a distance of not less than six inches from the edges of the new concrete foundation. The entire foundation so exposed shall be thoroughly cleaned in an acceptable manner, and a new asphalt concrete pavement surface of approved type and thickness shall be placed thereon and rolled in an acceptable manner by the permittee.

(2) 

Asphalt concrete pavement. In patching existing asphalt concrete pavement, the permittee shall cut back the existing pavement a distance of not less than one foot beyond the edge of the excavation, and to a minimum depth below the top of the existing pavement as follows:

(a) 

When any street patch dimension is less than five feet, the depth to the subgrade shall be a minimum of eight inches. After the subgrade is properly prepared, a six-inch-thick concrete foundation shall be placed by the permittee. The top of this concrete base shall be two inches below the existing pavement. After the concrete is properly cured, the permittee shall have the option to place a two-inch layer of asphalt concrete pavement surfacing or to have said work performed by the City. In the latter case a fee of $2.50 a square foot shall be charged against the permittee's deposit.

(b) 

When trench or patch dimensions are a minimum of five feet wide by at least 10 feet long, the permittee shall have the option of using a hot asphalt concrete base mix four inches thick and compacted with a ten-ton roller for the foundation course in lieu of the contract foundation as specified in Subsection C(2)(a) above, except that, in this case, the permittee shall be responsible for placing the two-inch top course.

(c) 

The total thickness of the pavement as specified in Subsection C(2)(b) and (c) is the minimum allowed and applies only to openings that are in residential streets in any one-family or two-family Residence Districts as defined in the Zoning Ordinance of the City. In all other streets constructed of pavement type other than reinforced portland cement concrete, the thickness of the pavement to be replaced will be as specified by the Commissioner, depending on whether the street is arterial, collector or local.

Editor's Note: See Ch. 331, Zoning.

D. 

Other surfaces. Any other surfaces disturbed by reason of the work performed under the permit shall be restored by the permittee as directed by the Commissioner.

E. 

Work may be done by City. The Commissioner may, in his discretion, cause any or all of the work contemplated in this article to be done by the City's own forces, or by contract or otherwise, in which case the City shall be reimbursed for any expense incurred thereby in accordance with the provisions of § 281-34, and the permittee shall have no claim against the City for loss of anticipated profits or for any other losses by reason thereof.

F. 

Permanent resurfacing. All street opening projects that exceed, in the aggregate, a length of two City blocks shall be permanently resurfaced in accordance with the specifications of this chapter by resurfacing the entire expanse of the affected street from curb to curb.

[Added 9-19-1989 by Ord. No. 226-1989]

G.

[Added 7-16-2002 by Ord. No. 137-2002]
