560 Code of Massachusetts Regulations.
The requirements set forth within the provisions of these regulations are intended to promote the general health, safety, welfare and convenience of the inhabitants of the Town of Groton by reducing the difficulty in responding to individual residences, commercial properties and nonprofit locations in cases of police, fire, medical or other emergency situations requiring immediate location determination and response; by facilitating the delivery efforts of the United States Postal Service through the creation of a naming and numbering system for all delivery locations; by decreasing the potential for traffic accidents caused by motorists searching for address locations; by allowing the use of information technology to provide for the efficient administration of Town government; by improving local census data gathering capabilities; by improving the accuracy of important real property legal documents requiring location information; and by assisting the planning efforts of a growing community.
A. 
Display of building numbers.
(1) 
Each and every building owner in Groton is responsible to ensure at all times, day and night, and in all seasonal conditions that the Town-assigned building number is displayed in a fashion and at locations which facilitate rapid and accurate response by Groton emergency service agencies as well as responders from surrounding mutual aid communities. These regulations provide the framework for naming of streets along with the assignment and display of building numbers. Extensive as they are, these regulations can neither identify nor define every building numbering situation that may arise. To come up with a building number display solution for a particular location, building owners must work within the spirit and intent of these regulations, apply common sense, and collaborate with both the Fire Chief and Building Commissioner to ensure the best solution.
(2) 
With regard to the display of building numbers, the building owner's on-going highest priority must be to display and maintain the assigned building number in such a manner that it is easy, simple and fast for emergency service agencies to accurately find the building when responding to a request for emergency services. Mundane as the topic may be, it is important to remember that at some point the proper display of building numbers may make the difference between life and death.
B. 
Enhanced 9-1-1 service.
(1) 
In 1990, Massachusetts enacted legislation for Enhanced 9-1-1 on a statewide basis in the commonwealth. This legislation established the Statewide Emergency Telecommunications Board (SETB) as the state agency responsible for coordinating and administering the implementation of Enhanced 9-1-1 and for promulgating standards to ensure a consistent statewide approach for Enhanced 9-1-1.
(2) 
The Enhanced 9-1-1 system automatically displays the address and telephone number of the emergency caller on a screen at all 9-1-1 communications centers in Massachusetts, commonly referred to as "public safety answering points" (PSAPs). There are approximately 270 PSAPs in the commonwealth, some of which are regionally based to answer calls for multiple communities.
(3) 
In the first half of 2009, the State 911 Department adopted regulations governing Enhanced 9-1-1 service for multiline telephone systems. The regulations require that, beginning July 1, 2009, any new or substantially renovated multiline telephone system (often referred to as PBX, Centrex®, or key set systems) shall provide the same level of Enhanced 9-1-1 service that is provided to single-line subscribers in Massachusetts. The regulations require that the operator of a multiline telephone system provide a sufficiently precise indication of a caller's location so that emergency response services may be dispatched to the specific location of the caller to further shorten response times and help save lives and property. Additional information is available on the State 911 Department website at www.mass.gov/e911, 560 CMR 4, Regulations Governing Enhanced 9-1-1 Service for Multi-Line Telephone Systems.
(4) 
It is the responsibility of every building owner in Groton, consistent with Massachusetts laws and regulations, to ensure that any and all wire-line telephone service on their premises terminates at the correct public safety answering point when 9-1-1 is dialed.

STREET CATEGORIES
A. 
COLLECTORA street with anticipated traffic equivalent to that generated by 50 homes or more or which serves abutting land zoned for business or industry.
B. 
DEAD ENDA street or street system which has only one means of ingress from or egress to a collector or minor street. The dead end category includes streets commonly called "cul-de-sacs."
C. 
LANEA dead-end street or loop street which cannot serve as access to more than 12 dwelling units and cannot be extended.

[1]
Editor's Note: For example, in Groton Peabody Street which connects Old Ayer Road to Farmers Row is a through street, and Champney Street which connects Main Street to Hollis Street is a through street.)
A. 
Campuses: In recognition of their nonstandard roads, driveways, and building layouts, campuses (e.g., schools, camps with multiple permanent buildings, retreat facilities, and similar properties) and campus-like properties shall adopt street names that are agreeable to the campus owner and to the Groton Fire Chief. In reaching this mutual agreement, both parties will give the highest priority to facilitating the fastest and most accurate response by both Town and mutual-aid emergency service responders.
B. 
Selection of street names: To prevent duplication of street names or the use of similar sounding street names, all street names used in Groton must be approved, in advance, by the Town Manager. The Town Manager will collaborate with the Fire Chief, the Building Commissioner, and the E-9-1-1 Database Liaison prior to approving a new street name. The Town Manager may solicit and consider, but need not use, street name suggestions from developers and residents.
C. 
Naming of private driveways: Naming of private driveways and shared driveways serving three or fewer units is prohibited unless the Fire Chief determines a name is necessary for public safety reasons.
D. 
Roadway ownership category: These street naming principles apply regardless of the legal ownership category of the roadway which vehicles traverse.
The Town of Groton has a wide variety of street patterns, types of land use and densities of development. Therefore, the roadway network and development trends in each area must be carefully studied to determine the most appropriate building numbers. At times this may require the use of different methods to assign numbers. In order to provide a basic framework for consistency in making these decisions, the following numbering principles shall be used.
A. 
Application of numbering principles: It is unrealistic to think that a numbering method can be described for every possible combination of building type, building design, road type, building orientation relative to the street, placement of external entrances, etc. Accordingly, the Town Manager or his/her designee will generally apply these numbering principles, using his/her reasonable discretion and judgment, when assigning numbers. It is important that numbers be assigned consistently to like or very similar situations. In this regard, when truly new numbering situations present themselves, the Town Manager will collaborate with the Fire Chief, the Building Commissioner, the E-9-1-1 Database Liaison, and the Information Technology Manager and agree on a solution. The agreed-on solution for the particular situation will be documented and used each time a like or very similar situation presents itself in the future. These documented situation-specific numbering solutions may be consolidated and included in future revisions to these regulations.
B. 
Campuses: In recognition of their nonstandard roads, driveways, and building layouts, campuses and campuslike properties shall adopt a numbering scheme that is mutually agreeable to the campus owner and to the Groton Fire Chief. In reaching this mutual agreement, both parties will give the highest priority to facilitating the fastest and most accurate response by both Town and mutual-aid emergency service responders.
C. 
Road ownership category. These street numbering principles apply regardless of the legal ownership category of the roadway upon which vehicles traverse.
D. 
Number interval method:
(1) 
This method shall be used to assign numbers for residential and nonresidential buildings.
(2) 
Numbers will be based on twenty-foot intervals along the center line of the street.
E. 
Single street number with unit designation:
(1) 
As a general rule, buildings with multiple external entrances will have each external entrance assigned a unit letter. When frontage on the street makes this impossible or impractical, the building will be assigned a street number using the twenty-foot-interval method.
(2) 
All units with external entrances will be assigned an alphabetic unit designation starting, when facing the building from the vehicular access, beginning with the lefthand corner and progressing from left to right (in a counter-clockwise direction) as shown on the following diagram:
258 page 7.tif
(3) 
All units with internal entrances will be assigned an alphabetic unit designation from left to right alternating along the inside of the hallway as shown on the following diagram:
258 Page 8.tif
(4) 
All units with internal entrances in buildings with multiple floors will be assigned a floor number followed by an alphabetic unit designation from left to right alternating along the inside of the hallway. Units accessed by a separate external entrance shall be assigned a floor number followed by an alphabetic unit designation as shown on the following diagram:
258 page 10.tif
F. 
Numbers assigned to driveway or front entrance: Numbers shall be assigned based on the location of the vehicular access to the building. Consideration may be given by the Building Commissioner, for new buildings, and by the Fire Chief, for existing buildings, to the assignment of numbers based on where the building faces the road when there is a demonstrated need for assigning the number in such a manner.
G. 
Numbers assigned to through streets: Through street numbering will begin at the end of the street with the shortest straight-line distance to the corner of Main Street and Station Avenue.
H. 
Even/Odd numbers: Starting at the end of the street with the shortest straight-line distance to the corner of Main Street and Station Avenue, the lefthand side of the street will be assigned odd numbers and the righthand side of the street will be assigned even numbers.
I. 
Hammerhead lots and other lots with obstructed visibility from the roadway: Within areas where development is situated on hammerhead lots or lots with obstructed visibility from the vehicular access to the building, the location of the residential building must be considered. When a building is located a considerable distance from the roadway or visibility to the building is obstructed from the roadway, the building number shall be determined using the vehicular access to the roadway.
J. 
Private rights-of-way (Residential):
(1) 
In situations where three or fewer buildings are located on a private unnamed right-of-way (sometimes referred to as a "shared driveway"), each residential building will be assigned a building number off the connecting public right-of-way or street. (See Chapter 381, Part 4, Shared Driveways, of the Code of the Town of Groton.)
(2) 
In situations where more than three residential structures are located on a private unnamed right-of-way (sometimes referred to as a "shared driveway"), the private drive shall be named. The Town Manager shall solicit and consider, but need not use, name suggestions from property owners on the road. Once a name has been approved, a Town standard street name sign shall be installed. (See Attachment 1 to Chapter 381, Code of the Town of Groton.)
(3) 
The buildings shall be numbered according to these principles using the number interval method. The property numbers shall be posted in accordance with the Town's street name sign standards.
K. 
Fractional numbers: Fractional numbers shall not be used. Alphabetical suffixes are acceptable when a secondary property designation must be assigned and no valid number is available. Alphanumeric suites and apartment numbers may also be used.
L. 
Use of "L" or "R" as a suffix: Use of the letter "L" to designate "left" or the letter "R" to designate "right" or the rear of a numbered building shall not be used.
M. 
Use of LL as a prefix or suffix: The letters "LL" shall be used only to designate lower level and may not be used for any other purpose.
N. 
Campuses: Campuses and campus-like complexes shall mark each and every building on the campus using a numbering system that is mutually agreeable to the Town of Groton and the property owner or owners. In reaching such mutual agreement, facilitation of rapid and correct response for public safety personnel shall be the highest priority consideration. Designation of campuses and campus-like complexes for numbering purposes shall be at the sole discretion of the Fire Chief.
O. 
Duplexes: Each unit in a duplex dwelling shall be assigned an alphanumeric designation in accordance with the provisions stated for multifamily houses.
P.

(1) 
For single-story multifamily dwellings, the unit's designation shall be composed of one or more alphabetic characters.
(2) 
For multistory multifamily dwellings, the unit's designation shall be composed of one or more numeric characters followed by one or more alphabetic characters. Spaces or hyphens between the numeric characters and alphabetic characters are not allowed. The numeric characters shall identify the floor upon which the unit is located, and the alphabetical characters shall uniquely identify the unit on that floor.
(3) 
Each floor in a multifamily building shall be assigned a unique floor number from top to bottom, with the ground floor being the first floor and increasing sequentially for each floor above the first floor, except basement units which shall be assigned the prefix "LL" (lower level).
(4) 
Each unit on a floor in a multifamily building shall be designated alphabetically with Unit A starting at the left corner of the building when facing the building from the vehicular access to the building. If there are more than 26 units on a floor, Unit 27 will be designated "AA," Unit 28 will be "BB" and so forth. Basement units shall be designated with the prefix LL (lower level) followed by an optional floor number and unit letter. Examples:
(a) 
The eighth unit from the left front corner of the building of a single-story multifamily dwelling would have the designation "H."
(b) 
The fifth unit from the left front corner of the building on the second floor of a multifloor multifamily dwelling would have the designation "2E."
(c) 
The 29th unit from the left front corner of the building on the third floor of a multifloor multifamily dwelling would have the designation "3CC."
Q. 
Numbering of accessory apartments: When an accessory apartment has been authorized on a particular piece of property, the primary residence shall use the assigned street number for the property . The accessory residence shall use the assigned street number for the property followed by an "A."
R. 
Apartments and residential condominiums: Each primary private access road to an apartment or residential condominium complex with three or more buildings shall be named, and a standard Groton street sign shall be installed. At the sole discretion of the Town Manager, in cases where the apartment units or residential condominiums are located near the vehicular access to the building or along shallow parking areas along the street, a separate street name may not be required.
S. 
Multiple-use properties: Each separate building should be assigned an individual number. For properties with narrow street frontage, the numbers may be borrowed from the next available number when necessary.
T. 
Commercial, office and industrial complexes: A choice must be made among several methods:
(1) 
Assign the number to the main building where all of the mail is to be received. Auxiliary buildings may be assigned separate numbers.
(2) 
Each principal building in the complex may require a separate number.
(3) 
For strip mall type shopping center developments, one number shall be assigned to each freestanding building in the strip mall, and each individual business shall be assigned a unique alphabetic unit or suite designation. Basement units shall be designed with the prefix "LL" (lower level). For security and emergency response purposes, the business name and assigned address of each business shall be placed on all of its entrances and loading areas.
(4) 
Interior mall shopping centers shall have one number assigned for the entire mall. Individual businesses shall be assigned a unique alphabetic unit or suite number. For security and emergency response purposes, units in such interior mall shopping centers with individual external entrances shall display the business name and assigned address at all external entrances and loading areas.
A. 
Street name approval: All proposed street names shall be submitted to the Town Manager for approval prior to the submission of any tentative or preliminary subdivision plan to the Planning Board or Building Commissioner, as appropriate.

A. 
Purpose: To ensure prompt delivery of emergency and routine services, it is important that the assigned property numbers be displayed on each property. Postal Service regulations require that each mailbox be identified. However, along many streets, mailboxes are not suitably located to provide for the identification and location of each residence. Therefore, some residents will need to display their property numbers in two locations, at the point of vehicular access from the right-of-way to the property and on the building.
B. 
Responsibility for display: It is the duty of the owner to ensure that the assigned property number is displayed in a conspicuous place.
C. 
Regulations for display:
(1) 
The numbers on the building shall be affixed in a place visible from the vehicular access to the building and driveway access area, as applicable.
(2) 
Whenever possible, the numbers shall be displayed near a light source to improve visibility at night.
(3) 
The numbers shall be on a background of highly contrasting color (light on dark or dark on light). The use of brass numbers as well as gold- and silver-colored numbers is strongly discouraged but may be used if the width of each number outline is at least 3/8 of an inch, at least three inches tall, and the number or numbers are displayed on a strongly contrasting background.
258 page 19.tif
For example, the combination of brass, gold-colored or silver-colored numbers on a natural color pressure-treated wooden post does not meet the strongly contrasting background requirement.
(4) 
The numbers shall be large enough (three-inch minimum) to be readable from the street.
(5) 
If the principal building is not visible from the street, the numbers shall be displayed on a granite post, gate post, or other conspicuous location on the property near the driveway. The numbers must be visible from both directions year round.
(6) 
If the principal building is shared with another person or occupant/user who has a separate entrance, and each entrance has been assigned an individual building number, then each should display his number near his doorway. Both numbers shall also be displayed in accordance with the regulation for display, stated above.
(7) 
If a building has more than one unit and the units are accessed by separate driveways, each building number and unit designation shall be displayed at the vehicular access to each unit.
(8) 
If the mailbox is not located on the street (public or private) by which the number has been assigned, the entire address (number and street name) shall be shown on the mailbox to avoid confusion. In these cases, it will be necessary to also display the number on the building, as described above.
(9) 
On corner lots, only one number will be assigned. To avoid confusion, the number must be displayed to face the vehicular access to the building.
D. 
Directional indicators for named street serving three or fewer residences: In addition to compliance with the regulations for display above, a directional marker must be displayed at the entrance to each individual driveway. The specifications for these directional markers are shown in Diagram 2, at the end of these regulations.
E. 
Removal of other numbers: It shall be the duty of the property owner and occupant, upon affixing the new number, to remove any different number which might be mistaken for, or confused with, the number assigned to that property by the Fire Chief.
F. 
Maintenance of Property Numbers: It shall be the duty of the property owner and occupant to maintain property numbers in accordance with these regulations.
See Code of the Town of Groton, Chapter 119, § 119-4, dated December 28, 2009.
See Code of the Town of Groton, Chapter 119, § 119-8, dated December 28, 2009.
If any provision, paragraph, sentence, or clause of these regulations is held invalid for any reason by a court of competent jurisdiction, all other provisions shall continue in full force and effect.
[Amended 10-1-2018 ATM by Art. 14]
These regulations shall take effect upon adoption by the Groton Select Board in accordance with Chapter 119, § 119-6, of the Code of the Town of Groton.
