Purpose. In 2000, the cities of Portland and Westbrook worked jointly to develop a gateway plan for the entrances of our communities along the Brighton Avenue corridor. The Brighton Avenue/Main Street Corridor Traffic and Streetscape Study identifies a number of safety and appearance improvements to the corridor, intended to provide a safer and more pleasing experience for the driver and pedestrian as they move through the corridor. This should, over time, increase property values in this corridor, creating an incentive for further investment.

Improvement standards. When there is new construction (i.e., an addition or new building), or when more than 20% of a property's activity or use changes, the owners are required to submit an application for site plan review, demonstrating how the following performance standards are to be met:

Minimum lot frontage: 200 feet.

Yard depths:

Maximum height: None.

Minimum lot frontage: 200 feet.

Yard depths:

Maximum height: 75 feet and up to five stories. Maximum height shall include mechanical equipment and architectural detail.

Noises created by construction and maintenance activities between 7:00 a.m. and 10:00 p.m. are exempt from the maximum permissible sound levels set forth in this section.

The following uses and activities shall also be exempt from the requirements of this section:

Limited retail uses. Retail may be allowed as an accessory use if the Code Enforcement Officer determines that the following conditions are met:

Hours of operation. The Code Enforcement Officer may approve operations outside these hours for emergencies, such as the need to repair a public utility or a public right-of-way as a result of a severe weather event.

Blasting. No more than eight production blasts may be conducted per calendar year. In addition to production blasts, safety blasts limited to no more than 1,000 pounds of explosive materials per blast may be conducted if necessary to maintain the safe operation of the quarry, but not for the purpose of producing rock for crushing or commercial sale. Except in the case of a safety emergency, safety blasts shall be conducted on one or more of the days when production blasts are conducted.

Truck traffic. Trucking may not exceed an average of 45 daily truck departures and may not exceed a peak limit of 105 truck departures in any single day. The average daily truck departures will be determined by dividing the total number of annual truck departures by the total number of annual operating days, to be reconciled on an annual basis. A "truck departure" is defined as any instance in which a loaded truck, containing material for sale or commercial processing, other than a pickup truck or a service vehicle truck leaves the quarry. An "operating day" is defined as any day quarrying activities occur at the quarry. For the purposes of calculating the average daily truck departures, the total number of annual operating days is to be calculated as follows:

Insurance. Maintain a minimum of $10 million in insurance coverage in aggregate for blasting.

Buffers, berms, and fencing. Maintain the existing visual buffer between the quarry and abutting properties and streets or a substantially equivalent visual buffer, as approved by the Code Enforcement Officer.

Unitrode site. Not work the quarry below the water table except in accordance with the monitoring plan developed by Sevee and Maher Engineers, Inc., and approved in advance by the City Engineer after consultation with the Maine Department of Environmental Protection's Mining Coordinator and Unitrode Project Coordinator.

Blast monitoring. Use third-party blast planning and monitoring and provide annual reports to the City to document blasting within the preceding 12 months. Video record all blast activities and maintain such records for a period of one year. These records will be provided upon request to the City.

Seismograph monitors. Provide off-site seismic monitors to all requesting property owners within 1/2 mile, to be monitored by a third party, to the extent such monitoring is not duplicative in the judgment of a third party providing such monitoring. Monitoring reports shall be kept for three years and shall be made available to the property owners and the City within 10 days of each blast.

Preblast surveys. Provide one third-party preblast survey to each requesting home or business within 1/2 mile radius of the quarry. Copies of the surveys shall be kept until blasting at the quarry has been completed, plus one year.

Weather conditions. Blast only during weather conditions which are favorable to mitigating off-site impacts, e.g., noise and dust.

Inspection and repair. Develop, in conjunction with the City, a process through which an independent third party will inspect claims of property damage that are raised by neighboring property owners. If any damage is determined, based on the independent review, to have been proximately caused by blasting, provide reasonable compensation for necessary repairs, as recommended by an independent third party.

Blast call list. Maintain and use a blast call list for any property owner within 1/2 mile of the quarry who requests inclusion on the blast call list. Property owners on the blast call list shall be notified not less than 24 hours before any scheduled production blast and telephoned or emailed, as the property owner has specified, not less than one hour before the actual production blast. In addition, production blasts shall be scheduled not less than two weeks in advance and notice of the blasts shall be provided on the City's website. Those property owners who prefer may request their notice to be sent by U.S. mail.

Access road and entrance. Maintain the existing paved access road below the grade of Spring Street and maintain the existing entrance onto Spring Street. Once the quarry has been in operation for at least six months, the quarry owner shall meet with the City and neighbors of the quarry in a public session to discuss the design of additional left-hand and right-hand turn lanes in Spring Street at its intersection with the new access road entrance to address traffic coming from or headed to County Road. No later than 12 months thereafter, the quarry owner shall commence construction of any required turn lanes and shall prosecute the same diligently to completion, provided the City shall use its reasonable, lawful authority, if necessary, to acquire any needed additional right-of-way width(s) and/or governmental approvals to accommodate the same; provided, further, the quarry owner shall reimburse the City for any reasonable expenses incurred and for the final fair market value of any real property interests it may have to acquire.

Vibration. Utilize electronic (digital) detonators for all blasts to reduce the off-site effects of blasting activities; not exceed a maximum of 0.50 inch per second peak particle velocity for blast vibrations as measured by any seismograph located under the provisions of Subsection E(2)(h) and 0.25 inch per second peak particle velocity for blast vibrations as measured at a baseline seismograph located at 2 Ledgeview Drive, Westbrook (City Tax Map 002-000-101); utilize laser profiling and borehole tracking as part of blast design and implementation to improve the effectiveness of drilling activities and to reduce the risk of fly rock from blasting activities; utilize a blast face profiler to reduce impacts of air blasts.

Noise. Limit noise levels for all blasting so as not to exceed 129 dBA, measured in accordance with Maine Department of Environmental Protection regulations Chapter 375, Section 10C(4), for one blast per day; 126 dBA for two blasts per day; 124 dBA for three blasts per day; 123 dBA for four blasts per day; limit daily operational noise levels for extractive industry so as not to exceed 75 dBA as measured at the property lines of the parcels on which the quarry is located; use synthetic screens, urethane liners in crushers, or their substantial equivalents to reduce noise levels associated with crushing and screening; limit on-site speeds to no more than 10 miles per hour; to the extent permitted by state and federal laws and regulations, minimize the volume of sound resulting from required sensors on on-site equipment through the use of sonar and similar alarm systems.

Dust. Not allow dust to migrate beyond the property line and take the following measures: enclose the producing areas of crushers so as to reduce the dust and noise generated by the crushing activity; pave the first 500 feet of any entrance from a publicly utilized right-of-way and install wheel washers in order to reduce off-site dust from vehicles leaving the unpaved area of the quarry; incorporate pre- and post-blast water mitigation to reduce the presence of dust created during blasting activities; utilize a vacuum sweeper and water truck, as needed, on all internal roads to reduce the presence of dust created during quarrying operations; utilize water fog nozzles as needed at all materials transfer points and stockpiles of quarried materials to reduce the level of dust created by quarrying operations; utilize two-sided truck trimming racks to ensure material is removed from the sides of trucks prior to the vehicles leaving the site; require load covers for trucks transporting material from the quarry operation.

Spillage. Perform a daily inspection of truck routes to remove any spillage of gravel, crushed stone, product, or debris from trucks leaving the quarry from the entrance to Spring Street up to and including the intersection of Spring Street and County Road and the intersection of Eisenhower Drive and Spring Street and shall provide cell phone contact numbers to requesting residents and to City officials so that the quarry owner may promptly respond to any request to remove any spillage from trucks leaving the quarry. Respond with cleanup activities immediately upon notification.

Community. Meet at least annually with a neighborhood working group constituted by the City, review relevant records with this group, and review and discuss compliance with the performance and use standards. The operator will send a responsible management representative and provide records reasonably related to compliance with the conditions. The operator will submit all of its business records as are reasonably related to compliance no less than quarterly to be kept on file at City Hall, provided that the operator may request that certain business records be kept confidential by the City to avoid compromising the operator's legitimate business interests. The initial meeting of the neighborhood working group shall be called by the City, but at that first meeting, the neighborhood working group shall assume control over all aspects of the group, both substantive and procedural, and shall open the group's membership to all persons or firms as it deems appropriate. The City and its officials thereafter shall serve only as a resource for the working group and, upon reasonable advance notice, shall provide for public meeting space for the group; provided, at a minimum, the City Council ward representative for this area of the City, or his/her designee, shall attend such meetings if so requested; provided further, subject to and consistent with Section 59 of the Consent Order, the working group may call for an audit if the group believes there is a substantial issue of noncompliance with the performance standards of this section.

Compliance audits. The City may initiate an audit of extractive industry operations to determine compliance with the performance and use standards in this section to be performed by an independent third party engaged by the City. The auditor shall provide the operator with not less than two working days' advance notice of any site visit and shall conduct any such visit during normal business hours. Not more than one audit may be performed in any twelve-month period. The results of the audit shall be made available to the operator. These compliance audits shall be separate from and not a limitation upon inspections by the Code Enforcement Officer.

The quarry owner shall comply with the reclamation plan submitted to the City. Any amendments to the reclamation plan shall receive the prior approval of the City Engineer pursuant to the then-current requirements of the Department of Environmental Protection.
