EXCAVATION PERMIT APPLICATION Apply for an Excavation Permit On-Line
Anyone wishing to open or excavate any street, must obtain a permit on a form provided by the Department of Highways. Each application for a permit must be accompanied by the required permit fee.
Work authorized by a permit shall be performed between 7:00 a.m. and 9:00 p.m., Monday through Friday form April 1st through November 15th, 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” section of the regulation shall apply.
The location of all utility facilities shall be determined sufficiently ahead of excavation work to avoid damage to those facilities and permit their relocation if necessary. The permittee shall, as specified by New Hampshire Law, RSA 374:51 and 374:55, call DIG SAFE at (1-888-344-7233) at least 72 hours prior to any excavation. The permittee shall also notify the Manchester Police and Manchester Fire Department, Manchester Transit Authority and Ambulance Services.
A Street Excavation permit gives the right to encumber a roadway with proper traffic control, as long as a minimum of one lane of traffic (11 feet wide) is provided on the street at all times. Access shall be provided to all property at night and on weekends and to all places of business at all times.
No more than 200 feet measure longitudinally shall be opened in any street at one time, except by special permission of the Department of Highways. No opening or excavation in any street shall extend beyond the centerline of the street before being backfilled and the surface of the street made passable to traffic.
Any street excavation restricting complete traffic movement must have an “ENCUMBRANCE PERMIT” in addition to the Street Excavation permit. This Encumbrance Permit will only be issued with an approved traffic control plan. If a complete street closure is necessary, at least seven (7) working days advance notice is required with confirmation of the proposed closure three (3) working days in advance of the actual street closure. The Public Works Director will review and approve any detours required.
Top
ENCUMBRANCE PERMIT APPLICATION Apply for an Encumbrance Permit On-Line
Encumbrance permits are required whenever work will require the full or partial blocking of a sidewalk, or street. Partial blocking is defined as less than eleven feet provided for the passage of traffic.
A legible sketch shall be provided by the applicant showing the street to be encumbered, and all signage and blockades being proposed. It is the policy of the Department of Highways to have these sketches/applications reviewed and approved by the Director of Public Works or his designee prior to the issuance of the permit. The sketch should be submitted at least seven days prior to the work commencing.
The encumbrance permit is issued in triplicate. One copy is given to the contractor. The remaining two copies are kept on file.
The Police Department, Fire Department and the Manchester Transit Authority (if the work is on an MTA route), are each faxed a copy of this permit, however, this does not release the contractor from his obligation to inform these Departments.
Insurance Requirements:
$1,000,000 General Liability and $1,000,000 Auto Liability (If permit is for a dumpster, then auto liability is not required).
Workman’s compensation (If permit is for a dumpster, then Workman’s Compensation insurance is not required).
The City of Manchester and Department of Highways must be listed as additional insured.

OFFSITE SEWER FEES
Some areas of the City have been designated as sewer improvement areas by the Board of Mayor and Alderman. These areas are listed below and shown on the attached plans. Applications for building sewer connection permits within these areas are subject to an offsite sewer improvement cost recovery fee as follows:
1. Hackett Hill Road Area $758.00 per unit of flow
2. Wellington Hill Road Area $600.00 per unit of flow
3. Youngsville Area $675.00 per unit of flow
The foregoing off-site sewer improvement cost recovery fees are based on an equivalent dwelling unit basis where one dwelling unit (of flow) is equal to a design average daily sanitary flow of 250 gallons per day. The off-site sewer improvement cost recovery fee will be paid to the Department prior to the issuance of the building sewer permit. (Section 52.116)
Per the general policy of the Department of Highways, when sewer main construction is proposed in a sewer improvement area, the sewer design flow, including groundwater infiltration, will be used to calculate the off-site sewer improvement cost recovery fee. Generally, the same calculations submitted to the NH Department of Environmental Services (NHDES) by a licensed Professional Engineer for a Discharge permit may be used.
Also per Department policy, any fees for groundwater infiltration into the sewer of a proposed development must be paid prior to the issuance of the first building sewer permit. The Public Works Director or his designee will determine the infiltration fee based on the sewer design calculations submitted to the NHDES.

Chapter 52.116 -Sewers
OFF-SITE SEWER IMPROVEMENT FEES EXAMPLE CALCULATION
Env-Ws 1008.03 Daily Flow Volume
Dwellings, per Bedroom = 150 gpd/bdm
Area # 1 Hackett Hill Road Area
1 Bedroom Home (lbr x 150 gpd/bdm1)/250gpd x $758.00 = $454.80
2 Bedroom Home (2br x 150 gpd/bdm1)/250gpd x $758.00 = $909.60
3 Bedroom Home (3br x 150 gpd/bdm1)/250gpd x $758.00 = $1,364.40
4 Bedroom Home (4br x 150 gpd/bdm1)/250gpd* x $758.00 = $1,819.20
Area # 2 Wellington Hill Area
1 Bedroom Home (lbr x 150 gpd/bdm1)/250gpd x $675.00 = $360.00
2 Bedroom Home (2br x 150 gpd/bdm1)/250gpd x $675.00 = $720.00
3 Bedroom Home (3br x 150 gpd/bdm1)/250gpd x $675.00 = $1,080.00
4 Bedroom Home (4br x 150 gpd/bdm1)/250gpd x $675.00 = $1,440.00
Area # 3 Youngsville Area
1 Bedroom Home (lbr x 150 gpd/bdm1)/250gpd x $600.00 = $405.00
2 Bedroom Home (2br x 150 gpd/bdm1)/250gpd x $600.00 = $810.00
3 Bedroom Home (3br x 150 gpd/bdm1)/250gpd x $600.00 = $1,215.00
4 Bedroom Home (4br x 150 gpd/bdm1)/250gpd x $600.00 = $1,620.00
Sample calculation for groundwater infiltration:
Assume (for this example only) infiltration = 1,800 gpd
Hackett Hill Road Area cost recovery fee = $758.00 per 250 gpd
Infiltration cost recovery fee = (1,800 gpd/250 gpd)x$758.00 = $5,457.60
