The director may order that this plan be designed by a traffic engineer and stamped by a professional engineer. G. Excavation and Repair Standards 1. All excavations on paved streets and sidewalks shall be pre-cut in neat straight lines with approved pavement breakers or saws. Saw cuts in streets shall be perpendicular or parallel to the flow of traffic. 2. All excavations in existing pavement within 36” of the edge of pavement or curb shall require the removal and replacement of all old asphalt completely to the shoulder or curb at no cost to the City. 3. Certain types of pavement breakers may be prohibited by the City when the use endangers existing substructures or other property or does not meet the trench finish requirements. 4. Pavement edges shall be trimmed to a vertical face. The width of the trench prior to pavement replacement shall be consistent the entire length of cut. The trimmed edges shall not vary by more than three inches for every ten (10)linear feet of cut. An approved tack material shall be applied to all edges of existing pavement to ensure the new patch has a water tight bond with the old pavement. 5. An additional six inches of pavement shall be removed from all sides of the excavation measured from the edge of the excavated trench.Unstable or damaged pavement shall also be removed from the perimeter of the excavation. 6. When multiple patches are required in a distance of seventy-five (75) feet or less the applicant shall be required to grind a minimum of 1.5” inches and overlay the entire area including between the excavations and shall repave as one trench. In cases where the existing pavement is in poor condition the director may modify or waive this requirement. 7. The joint of an asphalt patch for a street excavation shall not fall within the wheel path of a vehicular travel lane. In such cases the excavation shall be enlarged to the center of the lane or adjacent lane. 8. Feather joints shall not normally be acceptable for overlays of old patches on arterials or collector streets. Repairs are to be made by grinding to the desired depth and then matching in with new pavement. ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 07/15/2008 Effective 07/16/2008 6 9.

The applicant shall transport the material to a storage site to be designated by the City, except when these items are part of the surface restoration. All excavated granite blocks, concrete pavers, granite curb and cobblestones remain the sole property of the City. The contractor shall be responsible for any damage to the material during excavation or transportation. 10. The applicant shall be responsible for the cost to replace any street markings or traffic loops disturbed by the work. The repair or replacement work shall only be done by a contractor approved by the Director. 11. The maximum length of open trench in an excavation permissible at any time shall be two hundred feet. No greater length is to be opened for pavement removal excavation, construction, backfilling, repairing or any other operation without with the express written permission of the Director. 12. The applicant shall not remove, even temporarily, any trees or shrubs, which exist in any street right of way without first obtaining the written consent of the City Arborist. The City Arborist shall be notified of any trees that are damaged. The contractor shall be responsible for the repair or replacement of any damaged trees. 2. Fee Schedules A. A street opening permit fee shall be charged for all work performed within the City right-of-way. These fees are to cover the City’s inspection and administrative costs associated with the street opening permit program. The fee structure is intended to reasonably reflect a permittee’s proportionate share of such costs. The City will periodically review these fees and fee structure. In the event the fees assessed fail to reasonably reflect the City’s inspection and administrative costs, or applicant’s share of such costs are substantially disproportionate, the City will revise the fee amounts or fee structure accordingly. The tiered fee schedule is established to reflect the complexity of projects associated with each type of street and the fee shall be based according to the following unit rates. A list of arterial and collector streets is provided in Appendix A of this policy. In every individual case, however, a minimum fee of $53.00 shall be required, but in no case shall the amount of fee charged exceed $1,577.00. B.

This shall include proper guards or barricades, signs, traffic cones and traffic flaggers. B. Work flood lights and flaggers with lighted traffic control devices may be required during periods of reduced visibility or at night to protect the public from hazard. C. If the work is to take place on major arterial streets, the work shall be done at night or during week-ends as approved by the Director to reduce conflict with traffic. The director may wave this requirement in special circumstances. D. Each applicant shall conduct and carry out the excavation work in such a manner as to avoid unnecessary inconvenience and annoyance to the general public and residents of neighboring property. All material excavated from trenches piled adjacent to the trench or in any street shall be piled and maintained in such manner as to minimize erosion, and not endanger those working in the trench, pedestrians or passing motorists. Any materials placed or stored within a travelway shall be barricaded in compliance with the latest MUTCD standards. Where the confines of the street being excavated are too narrow to permit piling of excavated material beside the trench, the City shall have the authority to direct the applicant to haul the excavated material to a storage site and then haul it back to the trench site prior for backfilling. It shall be the applicant’s responsibility to secure the necessary permission ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 07/15/2008 Effective 07/16/2008 9 and make all necessary arrangements for all required storage and disposal sites. The contractor shall also meet BMP”S for non point source pollution control. 6. Right to Inspect A.

When required by the City the applicant shall provide the following materials testing data; 1. Samples of materials used for aggregate road base or subbase sufficient for testing requirements. 2. Results of lab grain size analysis testing for subbase/base. 3. Results of in place density testing of any road base or subbase. 4. Mix design and per cent asphalt content of any HMA used on the project. 5. Thickness and density testing results of pavement on the project. 6. All pavement shall meet the latest City/MDOT specifications for HMA. B. It shall be the duty of the applicant to guarantee and maintain the site of the excavation work in the same condition as it was prior to the excavation for thirty-six (36) months after the date the work is accepted by the City C. The City shall have the right to revoke a street opening and if any other necessary City, State or Federal permits have not been obtained, or if the applicant is not in compliance with applicable City, State or Federal rules, laws or regulations, or is deemed by the Director to be a threat to public safety. 7. Penalties Failure of an excavator to follow the standards outlined in this policy, shall result in a written warning for a first offense. If the applicant fails to follow these standards within one year of the written warning, he shall receive a $500.00 fine. No excavation or street opening permits shall be issued, and privilege to excavate shall be revoked until this fine is paid. If the applicant fails to follow these standards within one year of the second offense, he/she shall receive a second fine of $500.00 and have all excavation and street opening privileges revoked for a six month period. Potential offenses could be, but are not limited to substandard work, excavation without street opening permits, excavation without an excavation permit, and failure to make repairs in a reasonable amount of time. 8. Newly Constructed and Paved Streets 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 an excavation must be done within the five year moratorium, the City may issue a street opening permit and require the applicant to cold plane and relay the full width of the road surface on both sides of the street opening cut a distance of 20 feet from the furthest outside edges of the cut. If that repair overlaps the edge of a repair from a previous opening, the City ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 07/15/2008 Effective 07/16/2008 10 may require the applicant to relay 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 such as but not limited to cold planning and paving with a paving machine. To prevent unnecessary excavation after reconstruction or repaving, the City will issue a minimum 60-calendar day notice to the potentially concerned utilities, and adjacent property owners prior to the roadway being repaved. 9. Backfill Methods A. Backfilling 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 subbase and base material shall be sand or gravel consisting of hard durable particles free of vegetable matter, lumps or balls of clay. All aggregate subbase and base material shall meet the latest MDOT and City specifications. B. Backfill material shall be placed in lifts eight to ten (10) inches. Aggregate subbase shall be fifteen (15) inches for residential streets, twenty-one (21) inches for collector streets and twenty-seven (27) inches for arterial streets and aggregate base shall be three inches for all streets. C. The City may require the contractor or utility 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 be borne by the excavation contractor. D. When backfilling is done by controlled density backfill, also known as flowable 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 excavator shall take hydrostatic pressures into consideration and brace structures accordingly. The flowable fill shall contain the water reducing and air-entraining admixture "DaraFill" as manufactured by Grace Construction Products of Cambridge, MA or approved equal. This method may be used during winter excavations, or when there are no feasible mechanical methods to backfill and compact. ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 07/15/2008 Effective 07/16/2008 11 10. Excavation Maintenance A. The applicant shall prosecute with diligence and expedite the completion of the excavation work to restore the street as specified in section 9. 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 two 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 reasonable rate of speed. The applicant shall maintain the temporary paving and trenches for a period not to exceed thirty (30) calendar days. At this time, the contractor shall install permanent pavement over the excavation. All excavations shall be kept safe for pedestrian and vehicular traffic until the excavation has been permanently resurfaced. All cold patch installed during winter excavations shall be replaced with permanent HMA no later than June 15. 11. Surface Restoration A. Permanent resurfacing of excavations in streets and sidewalks shall be the responsibility of the applicant. Resurfacing shall normally be completed the same day the excavation is compacted to finish grade. The replacement of existing bituminous pavement shall be done with HMA meeting the requirements of the latest MDOT 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 are normally as follows; Arterials six inches, Collectors four inches and residential streets three inches. Arterials and collectors normally require two inches of surface pavement and residential streets normally require one and a half inches. The surface of the replacement pavement shall match the grade and type of the surrounding pavement. 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 MDOT and City specifications. All joints longer than fifty (50’) linear feet in length and more than ten (10’) linear feet wide 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. 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. B. 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. ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 07/15/2008 Effective 07/16/2008 12 C. 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. A grass mix approved by the City Arborist shall be used. The applicant shall be responsible for grass growth within two months of planting or by June 15 of the following year for replanting work done after September 15. The Director may require an erosion control mesh, sod or other restoration method to be placed under special conditions, such as steep slopes and drainage ditches. The Contractor will comply with erosion control standards required by the Maine Department of Environmental Protection and the City. D. Repair of existing brick or concrete paver walkways shall be made with the existing stones that have been removed prior to any excavation. All brick or concrete pavers damaged by the contractor shall be replaced in kind at the contractor's cost. The replacement aggregate base shall be compacted over a woven geotextile. The pavers shall be placed on a one inch thick sand layer consisting of 100% passing a 3/8 inch sieve, but not more than 3% passing a No. 200 sieve. The pavers shall be compacted into place with a vibrating plate compactor. The Contractor shall be responsible for the paver replacement for a twenty-four (24) month period for damages relating to poor compaction and paver placement. This work shall be done in accordance with the Standard City Specification for Concrete & Brick Pavers. E. Repair of existing brick and concrete paver walkways on Lisbon Street from Chestnut Street to Main Street shall be made with the existing stones that have been removed and cleaned prior to any excavation. After initial backfilling with compacted subbase, a twelve inch (12") Compacted (MDOT) Type B aggregate base shall be installed. A four inch MDOT Grade binder course shall be installed on the compacted aggregate base. A three quarter inch setting bed of MDOT Grade asphalt shall be place over the binder. It shall be leveled with a screed between two 3/4" bars to produce a consistently even bed, then rolled with a water filled shaping roller. A two percent neoprene modified asphalt adhesive shall be used to set the pavers to finish grade and original pattern. The hand tight joints shall be a maximum of 1/8". The joints shall be filled with a dry sand and mortar mix swept into them until full. Joints around site elements shall be filled with an latex grout, matching the original. Any expansion joint removed shall be replaced with a premolded expansion joint fill of "Self-Expanding Cork," as manufactured by the Construction Products Division, R.W. Grace and Company or approved equal. The joint shall be filled with a two compound polysulfide self-leveling compound, matching the original joint sealant. ---PAGE BREAK--- EXCAVATION AND STREET OPENING POLICY Updated 07/15/2008 Effective 07/16/2008 13 Appendix A Federal Highway Administration Functional Classification of Lewiston Streets Arterial Streets Alfred A.
