Newly Constructed and Paved Streets A. To maintain the best travel surface feasible, there shall be no excavation on newly paved or substantially repaired streets for a period of five years except in emergency situations. If a City street absolutely must be opened to restore an existing essential utility service within the five year moratorium, the City may issue a street opening permit. The following conditions for street restoration shall apply: B. If the repair can be performed by excavating in one lane and not excavating across, the centerline of the street or road then the patch is to be paved with binder and surface flush with the existing surface pavement for the first year. The next year the Applicant shall return and mill one foot wider than the original patch in all directions approximately one inch in depth. This is to be paved with surface pavement flush with the existing pavement. The Applicants 36 months of maintenance responsibility for the patch shall begin when the City inspects and accepts the final street restoration. C. If the Applicant is required to excavate or trench across the centerline of the street or road, the patch is to be paved with binder and surface ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 05/07/2013 12 flush with existing surface pavement for the first year. The next year the Applicant shall return and mill the original patch curb to curb the full width of the street a distance of twenty (20) feet from the furthest outside edge of the original street opening approximately one inch in depth. The cold planed area shall then be repaved with one inch of surface pavement utilizing a paving machine and compaction equipment in compliance with the most recent Me DOT and City specifications. D. If any street opening overlaps the edge of a previous street opening, on a moratorium street, the City may require the Applicant to cold plan and repave the full width of the road to the furthest edge of that previous repair. The permit fee will be based upon the type of pavement (arterial, collector, residential, sidewalk, etc) and the total area of the opening in the street. The Director, may require excavations that are performed during the five year moratorium be treated with the infrared process or other approved method. E.

Backfill Methods A. Backfilling material in any street opening or excavation shall be compacted to a degree equivalent but, not less than the undisturbed ground in which the trench was dug, or 95% of relative maximum compaction, whichever is greater. Compaction of the layers of fill shall be done by mechanical tampers, vibrating plate compactors, or by trench rollers as required by the soil in question and sound engineering practices. Aggregate sub base and base material shall be sand or gravel consisting of hard durable particles free of vegetable matter, lumps or balls of clay. All aggregate sub base and base material shall meet the latest MDOT and City specifications. B. Backfill material shall be placed in lifts eight to ten (10) inches.

C. The City may require the Applicant to provide soil tests performed by a recognized soil testing laboratory or registered professional engineer specializing in soil mechanics when the City deems necessary. In order for the resurfacing to be permitted, such tests must show that the backfill material meets the minimum requirements prescribed by the City. All expenses of such tests shall be borne by the Applicant. The City reserves the right to test the material, and if it does not meet specification, the cost to remove and replace the material shall also be the responsibility of the Excavation or Contractor. When backfilling is done by controlled density backfill, also known as flow able fill, the fill shall not exceed 125 psi after 28 days and shall be capable of being excavated. The excavation shall be properly protected until the material has "set-up" any and all protection shall conform to Federal and State MUTCD standards. When backfilling, the Applicant shall consider hydrostatic pressures and brace structures accordingly. The flow able fill shall contain the water reducing and air-entraining admixture "DaraFill" as manufactured by Grace Construction Products of Cambridge, MA or approved equal.

The Applicant shall perform such restoration work so as not to obstruct, impede or create a safety hazard. B. Unless otherwise authorized by the Director, temporary resurfacing of streets shall consist of a cold patch when HMA is not available or HMA pavement at a minimum depth of three inches. All temporary HMA shall be compacted so that it is hard and smooth enough to be safe for pedestrian travel on sidewalks, and vehicular traffic on streets traveling at a normal rate of speed for the street or road involved. The Applicant shall maintain the temporary paving and trenches throughout the winter season as needed. Poor maintenance of any utility excavation at any time shall be considered a violation of the City’s Excavation Policy. All cold patch or other temporary pavement installed during winter excavations shall be removed and replaced with permanent Hot Mix Asphalt (HMA) meeting Me DOT Specifications no later than June 15. ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 05/07/2013 14 11. Surface Restoration A. Permanent resurfacing of excavations in streets and sidewalks shall be the responsibility of the Applicant.

The replacement of existing bituminous pavement shall be done with HMA meeting the requirements of the latest Me DOT and City specifications. When small excavations are resurfaced by hand, the compacted pavement thickness shall not exceed two inches in depth for any layer of pavement. For machine paving the maximum compacted thickness for a single course of pavement shall be three inches. The thickness of base pavement requirements for the types of streets listed is as follows: Arterials five inches, Collectors three inches and residential streets two and a half and a half inches. Arterials and collectors normally require one and one half (1 ½) inches of surface pavement and residential streets normally require one and a quarter (1 ¼) inches of surface pavement. The surface of the replacement pavement shall match the grade and type of the surrounding pavement. All (HMA) pavement used on City Streets shall be a Me DOT approved mix design. B. When an area to be repaved exceeds one hundred (100) square yards, resurfacing shall be accomplished using self-propelled paving equipment complying with the latest Me DOT and City specifications. All joints shall be cleanly saw cut with an approved mechanical pavement saw prior to removal of the old pavement. The Director may require the surface of the new pavement to be infrared treated when completing permanent repairs if necessary due to a mismatched joint or other surface defect. The infrared or other approved process if required shall be performed on arterials and collectors not less than six months or more than twelve (12) months from the date of resurfacing. C. Replacement of Portland cement concrete pavement shall be with an approved Portland cement concrete mixture and with reinforcement, thickness and contraction joints equal to that which was removed during the excavation. The City Engineer shall provide the specific requirements for the project. D. The restoration of existing grass areas, shall be to backfill with clean fill in compacted 12 inch lifts with the final six inches back filled with a screened loam to match existing.
