A. 
Number of spaces. Adequate off-street parking must be provided to service all increases in parking demand created by new structures or additions or created by change of use. The number of parking spaces provided must be as required in § 123-15B, unless the special permit granting authority or the Planning Board in either performing site plan review or responding to a request for determination by the Building Inspector finds that a lesser provision would be adequate for all parking needs because of such special circumstances as shared parking for uses having peak parking demands at different times, unusual age or other characteristics of site users, company-sponsored carpooling, or other measures which reduce parking demand.

Location of spaces. Required parking spaces must be on the same lot as the use they serve, except that crediting the following may be authorized on special permit by the Planning Board for cases where both the use and the parking are located within either or both the Commercial District or the Village Overlay District, upon determination by the Planning Board that, subject to conditions regarding location, egress design, landscaping and screening, or other matters doing so will be more beneficial to the vicinity than the alternative of requiring all demand to be met on site, and will not result in departure from historic patterns of land or street usage or substantially add to congestion or hazard:[1]
[Added by 5-29-2007 ATM, Art. 17]
(1) 
Legal on-street parking spaces not otherwise assigned or credited, if on the same side of the street and extending not more than 10 feet beyond the extended side lines of the premises.

[Amended by 6-5-1972 STM, Art. 5]
E. 
Driveways. Use of land for shared driveways is permitted in all districts, However, a shared driveway shall not be considered to adequately provide access for parking as required by this chapter on any lot for which a shared driveway is proposed as the sole means of access for parking unless the Planning Board so authorizes in performing site plan review under § 123-2C of the Zoning Bylaw or under a special permit. Authorization shall be granted only if all shared portions of the drive are to be paved and the Board determines that the arrangement improves public safety, such as by reducing the number of curb cuts on a major road or by avoiding a driveway at a potentially dangerous location; or serves environmental protection, such as by eliminating a wetlands crossing; and unless the Board further finds that the use of a shared driveway does not circumvent the intent of the Subdivision Control Law.[2]

A. 
No activity shall be permitted in any district unless it can be demonstrated that its operation will be so conducted that the following standards will be met:

No vibration, odor or flashing shall be normally perceptible more than 400 feet from the premises if located in the Industrial or Commercial Districts or more than 100 feet from the premises if located in a residence district. Interference originating in Commercial or Industrial Districts shall not normally be perceptible more than 100 feet within a residential district.
(2) 
Cinders, dust, fumes, gases, radiation or trash or other waste shall be effectively confined to the premises or disposed of.
(3) 
On-site disposal of industrial wastes (as defined in Title 5 of the Massachusetts Environmental Code) shall be allowed only in volumes and concentration such that resultant groundwater quality at the boundaries of the premises will not fall below the standards established by DEQE in Drinking Water Standards of Massachusetts.
(4) 
Premises involving the preparation, use or storage of toxic or hazardous materials shall make provisions to protect against discharge or loss of such materials through corrosion, accidental damage, spillage or vandalism through such measures as provision for spill control in the vicinity of chemical or fuel delivery points, secure storage areas for toxic or hazardous materials and indoor storage provisions for corrodible or dissolvable materials.
B. 
The Zoning Agent may require that applicants furnish evidence of probable compliance with the above requirements, whether by example of similar facilities or by analysis and certification by a professional engineer. Issuance of a permit on the basis of that evidence shall indicate acceptance of the conformity of the basic structure and equipment, but future equipment changes and operating procedures must be such as to also comply with these requirements.
