In the RA, RB, RLF and A Districts, no structure used for residential purposes shall be erected to a height greater than 40 feet. Structures used for nonresidential purposes in said Districts shall not be erected to a height greater than 35 feet. Chimneys, spikes, towers and other projections not used for human occupancy may be constructed above the foregoing height limitations upon the grant of a special permit by the Board of Appeals; provided, however, that no wireless communications facility shall be erected except in compliance with Article XVI, Wireless Communications Facilities.
[Added 5-3-1999 ATM by Art. 22]
A. 
A lot which contains a nonresidential use in a Residence A, Residence B, Residence Lake Front or Agricultural District shall contain a buffer area at the perimeter of the lot. The buffer area shall consist of trees, shrubs, vegetation and topographic features sufficient to separate and/or visually screen the use from abutting properties in a residential district and shall be located on the same lot as the nonresidential use. For the purposes of this section, the following shall not be considered nonresidential uses:
(1) 
Lawful and permitted accessory uses to a residential use.
(2) 
Home occupation.
(3) 
Home professional office.
(4) 
Home personal service.

The buffer requirement shall not apply with regard to the area adjacent to the street providing the legal frontage for the lot. The buffer requirement shall not apply to nonresidential uses which are located on a lot which abuts a residential district but, rather, shall apply only to nonresidential uses which are upon premises located within a residential district.
C. 
Buffer areas shall remain in their natural state. If, in the opinion of the Planning Board, the current natural state is insufficient to adequately separate and/or screen the site from abutting properties, additional trees, shrubs, plantings or fencing may be required.
D. 
Activities and structures not permitted within the buffer areas include, but are not limited to: light poles and/or fixtures; parking lots; driveways; buildings; athletic playing fields; playgrounds. Pedestrian and bicycle trails may be located within buffer areas.
E. 
Upon a finding by the Planning Board that a buffer of lesser width would be sufficient to screen and/or separate the use from adjacent property, the width of the buffer may be reduced. The buffer width requirement may also be reduced in the event that the lot was previously developed and used for a permitted use within the district and permanent structures were erected within the buffer area. In those circumstances, it is the intent of the Board not to waive the buffer requirement, but, rather, to provide alternative screening arrangements, such as fencing and planting where possible.
Earth removal shall be permitted only in accordance with Chapter 96, Earth Removal, of the Bylaws of the Town of Hopkinton, regardless of zoning district.
[Amended 3-7-1963 ATM by Art. 35]

A. 
Purpose. The purpose of this section is to preserve the natural and cultural resources of the Town by insuring that development of land for residential use does not consume all or a significant portion of the town's woodlands, fields, farmlands, historic structures and landscapes, cart paths, stone walls, geologic formations, watercourses, wetlands, riparian zones, groundwater recharge areas, hilltops, scenic vistas, areas of critical environmental concern, vernal pools and other significant open spaces, and that such development is undertaken with respect for the land and the town's natural resources. It is the intent of the Town to encourage that residential development be undertaken in accordance with the provisions of the open space and landscape preservation development section of this Chapter when residential development is to occur.
B. 
Applicability. Any parcel or parcels of land which, individually, or, if in common ownership with a contiguous parcel or parcels on the effective date of this section, together contain 10 acres or more, shall be subject to the provisions of this section. The development for residential purposes by the subdivision of land as defined in MGL c. 41, § 81L, of any parcel or parcels of land owned individually or under common ownership which comprises 10 acres or more and the development of which occurs within any five-year period shall be considered a residential subdivision of 10 acres or more. For purposes of calculating the size of the parcel or parcels, the area comprising new lots and road rights-of-way shall be included.
C. 
Regulations.
(1) 
No residential subdivision of 10 acres or more shall be permitted except after application and approval pursuant to Article XVII, Open Space and Landscape Preservation Development (OSLPD) of this Chapter.
(2) 
After application for approval of a residential subdivision of 10 acres or more pursuant to the OSLPD, the Planning Board shall determine whether the proposal complies with the requirements and criteria of that article. If the Board issues a special permit for an OSLPD concept plan, any subsequent subdivision of the affected parcel shall be conducted in accordance with Article XVII, OSLPD. If the Board does not find that the plan meets the requirements and criteria of Article XVII, OSLPD, the applicant may in that event determine whether to pursue development under the OSLPD by revising the plan to meet the requirements and criteria of the OSLPD or by proposing a conventional subdivision.
(3) 
In making the determination as to whether development must proceed pursuant to Article XVII, OSLPD, or pursuant to the procedures governing conventional subdivisions, the Planning Board shall evaluate both plans and proposals and select the development method which most closely incorporates the purpose, criteria and requirements of Article XVII, OSLPD, and satisfies, to the greatest extent possible, the purpose of this section.
