[Adopted 3-8-1983 by Art. 3]
Street opening permits shall be issued by the Public Works Director of the Town of Bedford. Anyone wishing to open or excavate in any street must make an application for a permit on a form provided by the Public Works Director. Each application for a permit must be accompanied by a fee in accordance with the fee schedule on file in the office of the Department of Public Works.
Work authorized by a permit shall be performed between the hours of 7:00 a.m. and 7:00 p.m. weekdays, unless the permittee obtains written consent from the Public Works Director to do the work during another time. Such permission shall be granted only in case of an emergency or in the event the work authorized by the permit is to be performed in traffic congested areas. In case of an emergency, the emergency provisions of Article IV shall apply.
No opening or excavation in any street shall extend beyond the center line of the street before being backfilled and the surface of the street made passable to traffic.
No more than 300 feet measured longitudinally shall be opened in any street at one time, except by special permission of the Public Works Director.
Every permittee will be required to place around openings, excavations, encumbrances, or obstructions such barriers, barricades, lights, warning flags, and danger signs as may be required by the Public Works Director to protect the safety of the general public.
During the hours of darkness, adequate artificial lighting devices are required to call attention to and indicate the actual location of obstructions and hazards.
All barricades, warning signs, lights, temporary signals, and other protective devices shall conform with the edition of the Manual on Uniform Traffic Control Devices for Streets and Highways, current on the date of application for the permit; which Manual is approved by the Federal Highway Administrator as the national standard for all highways open to public travel.
Traffic control devices shall be set up prior to the start of construction or maintenance operations and shall remain in place only as long as needed, as required by the Public Works Director.
Advertisements, notices, and signs other than for traffic control shall not be displayed on or attached to any barricade or fence in any highway.
A minimum of one lane of traffic shall be provided on all streets at all times. The minimum width for temporary traffic lanes is 11 feet. Access shall be provided to all property at night and on weekends and shall be provided to all places of business at all times.
If a complete street closure is necessary, at least seven working days' advance notice is required with confirmation of the proposed closure three working days in advance of the actual street closure.
The Public Works Director will review and approve any detours required. If an emergency necessitates the complete closing of a street, the closing will be governed by Article IV, Emergency Highway Closings.
When the work area encroaches upon a sidewalk, walkway, or crosswalk area, protective barriers, together with appropriate warning and guidance devices and signs, must be utilized so that the passageway for pedestrians is safe and well defined.
The location of all utility facilities shall be determined sufficiently ahead of trench excavation work to avoid damage to those facilities and permit their relocation, if necessary.
Property or street line monuments, survey reference points, and permanent survey bench marks shall not be removed or disturbed, unless specifically permitted in writing by the Public Works Director.
Provisions shall be made to provide for proper drainage during construction, and the permittee shall be responsible for all claims for damage or injury whatsoever that may arise from the obstruction or use of any public sewer or drain in connection with the work contemplated under the permit.
Shade trees shall not be cut down, trimmed, or otherwise injured. Where it is necessary to cut and remove pavement, curb, sidewalk, and/or other surface improvement, the material shall be cut and removed by means of equipment suitable to the type of material to be removed and in a manner which results in a minimum amount of damage to adjacent improvements.
Excavated material shall be replaced or backfilled in layers or courses not to exceed 12 inches in compacted thicknesses and shall be compacted at or near optimum moisture content using pneumatic tampers, vibratory compactors, or other approved means.
The material shall be compacted to not less than 98% maximum dry density as determined by the Standard Proctor Method in accordance with Standard Specifications.
If unsuitable for backfill, excavated material shall be replaced with granular backfill as specified in the Standard Specifications for Road and Bridge Construction, State of New Hampshire Department of Public Works and Highways, hereinafter referred to as the "New Hampshire Standard Specifications."
Water shall be uniformly applied during compaction in the amount necessary for proper consolidation, but puddling will not be allowed.
The minimum depth to any substructure, except manholes, vault entrance tubes, valve casings, and catch basins, shall be 24 inches below the surface of the nearest edge of the traveled portion of the street, and no excavation shall be less than 20 inches in length or width.
Within the asphalt paved areas, crushed gravel (as described in New Hampshire Standard Specifications) equal to the existing gravel course shall be placed in layers not exceeding six inches loose depth and thoroughly compacted. In no case shall the compacted depth of crushed gravel be less than 12 inches.
In other areas, the present surface type shall be restored by placing similar material on top of the trench to a depth equal to that existing before excavation. Any existing grassland, additionally, shall be fertilized and reseeded. Any asphalt or concrete sidewalk shall have surfaces of equal depth, kind, and quality placed.
As the work progresses, all streets shall be thoroughly cleaned of all rubbish, excess earth, rock, and other debris resulting from such work.
After an excavation is commenced, the work shall be prosecuted with diligence and expedition and shall be completed and the street restored to its original condition, or as near as may be, so as not to obstruct the public places or travel thereon more than is reasonably necessary. In any event, the surface of the street shall be permanently restored within a period of time not to exceed five days from the date of completion of the project.
The Public Works Director, as a condition of the permit, reserves the right to restore the highway or cause the same to be restored under his directions, and the permittee shall reimburse the Town for any or all liability and expense suffered by reason of such work.
The permittee further agrees to indemnity and save harmless the Town of Bedford, New Hampshire, from all claims for damage or injury whatsoever that may arise from the encumbrance, obstruction, occupation, or use of said highway, and the applicant shall be accountable for all damage that may occur on account of said encumbrance, obstruction, or use of the aforesaid highway, the Town of Bedford, in no case, assuming any responsibility or liability by reason of granting the permit.
The person, partnership, firm, corporation, etc., who obtains the permit to excavate a Town highway, shall be responsible for said excavation for 30 months after all work contemplated under the permit has been completed and the Highway Department so notified, and may be ordered by the Public Works Director at any time during the thirty-month period to improve or replace the work.
Each applicant for a permit shall be accompanied by a plan drawn to an approved scale, sufficient in detail to provide for easy field location of the work. Upon completion of the pavement restoration, the Department of Highways shall be immediately notified as to the location and time of completion.
