A.
Classification. In accordance with the Comprehensive Plan of the Town of Cumberland and for the purposes of these standards, streets are classified according to the average daily traffic (ADT) they are intended to serve, as calculated by the number of average daily trips, as follows:
(1)
Average daily trip. "Average daily trip" shall be defined as the anticipated number of daily vehicle trips generated by a use as established by the Trip Generation Manual, published by the Institute of Transportation Engineers, 1991, as revised. If the developer disagrees with the estimated number of trips per day generated by a particular use as listed by the Trip Generation Manual published by the Institute of Transportation Engineers, the developer may request a waiver of these standards if information is submitted demonstrating that the Trip Generation Manual estimate is inaccurate. Table 1 lists the estimated number of average weekday trips for residential uses.
Table 1 | |
|---|---|
Housing Type | Average Weekday Trip Generation Rates (trips per dwelling unit) |
Single-family detached | 10 |
Duplex, multiplex, townhouse, apartments, condominium, etc. | 8 |
Mobile home | 5.5 |
Retirement home | 3.5 |
(2)
Arterial streets. Arterial streets and highways serve primarily as major traffic ways for travel between and through towns.
(3)
Residential private streets. Private streets serve as feeders to access, subcollector, and collector residential streets and may be the principal entrance streets of a residential subdivision. Private streets are permitted only when the average daily traffic is less than 50.
(4)
Residential access streets. Access streets serve primarily for access to abutting residential properties and as feeders to other residential streets of equal of greater capacity. Access streets are intended to serve subdivisions with average daily trips less than 200.
(5)
Residential subcollector streets. Subcollector streets serve as collectors from access or private streets and as feeders to collector streets; they are intended to serve subdivisions with average daily trips of 200 to 500.
(6)
Residential collector street. Collector streets serve as collectors from subcollector streets and as feeders to arterial streets; they are intended to serve subdivisions with average daily trips equal to or greater than 500.
[Amended 12-27-2021]
(7)
Commercial access streets. Access streets shall be defined as streets servicing commercial and industrial subdivisions with average daily trips less than 2,000.
(8)
Commercial collector streets. Collector streets shall be defined as streets servicing commercial and industrial subdivisions with average daily trips greater than 2,000.
(9)
Classification of street types will be made by the Planning Board within the considerations outlined above.
B.
Layout.
(1)
Proposed streets shall conform, as far as practical, to such comprehensive plan or policy statement as may have been adopted, in whole or in part, prior to the submission of a preliminary plan.
(2)
All streets in the subdivision shall be so designed that, in the opinion of the Planning Board, they will provide safe vehicular travel while discouraging movement of through traffic over local streets.
(3)
The arrangement, character, extent, width, grade and location of all streets shall be considered in their relation to existing or planned streets, to topographical conditions, to public convenience and safety, and their appropriate relation to the proposed use of the land to be served by such streets. Grades of streets shall conform as closely as possible to the original topography.
(4)
In the case of dead-end streets, where needed or desirable, the Planning Board may require the reservation of a minimum thirty-foot-wide utility easement and/or minimum twenty-foot-wide right-of-way for pedestrian and/or bicycle traffic. The Planning Board may require that additional right-of-way widths be provided if it determines that future extension of the street may occur. Such additional widths shall be consistent with the right-of-way width of the dead-end street.
(5)
In front of areas zoned and designed for commercial use, or where a change of zoning to a zone which permits commercial use is contemplated by the municipality, the street right-of-way and/or pavement width shall be increased by such amount on each side as may be deemed necessary by the Planning Board to assure the free flow of through traffic without interference by parked or parking vehicles and to provide adequate and safe parking space for such commercial or business district. In no case shall the street have a right-of-way width and pavement width less than that specified in Table 3.
(6)
Where a subdivision borders on or contains a railroad right-of-way, the Planning Board may require a street approximately parallel to and on each side of such right-of-way at a distance suitable for the appropriate use of the intervening land, as for park purposes in appropriate districts. Such distances shall also be determined with due regard for approach grades and future grade separations.
(7)
Where a subdivision borders an existing narrow road (below standards set herein) or when the Comprehensive Plan indicates plans for realignment or widening of a road that would require use of some of the land in the subdivision, the applicant shall be required to show areas for widening or realigning such roads on the plan, marked "Reserved for Road Realignment (or Widening) Purposes." It shall be mandatory to indicate such reservation on the plan when a proposed widening or realignment is shown on the Official Map. Land reserved for such purposes may not be counted in satisfying setback or yard or area requirements of Chapter 315, Zoning.
(8)
Where topographic and other site conditions allow, provisions shall be made for street connections to adjoining lots of similar existing or potential use, for the purposes of facilitating public safety services and/or to enable the public to travel between the two subdivisions without the need to travel on a collector street. When a street connection is not feasible or desired, a "live end" street shall be shown on the plan which allows for a pedestrian or bike trail connection to the abutting parcel.
(9)
The extension or continuation of an existing street right-of-way less than that specified herein may be permitted with the approval of the Planning Board.
(10)
If deemed necessary by the Planning Board, the subdivision may be required to provide at least two street connections with existing public streets or streets on an approved subdivision plan for which a bond has been filed.
(11)
Entrances, either proposed driveways or streets, onto existing state aid or state highways must be approved by the Maine Department of Transportation. Copies of such approval shall be submitted to the Planning Board at the time of final review.
(12)
Utility plans must be approved by the responsible utilities. Copies of written approval shall be submitted to the Planning Board at the time of final review.
(13)
If the Planning Board determines that future subdivision will occur on land adjacent to or near the proposed subdivision, whether it is owned by the applicant or not, then the Planning Board shall retain the right to require the developer to meet the requirements for collector street design and construction as specified herein at no cost to the Town.
C.
Street naming and numbering. The assignment of street names and unit numbering shall be in conformance with Chapter 246 of the Cumberland Code.
D.
Street name signs. Street name signs shall paid for by the applicant but furnished and installed by the municipality.
E.
Traffic control devices. The developer shall furnish and place all appropriate signing and pavement markings required for the proper control of pedestrian, bicycle and vehicular traffic within the subdivision. The types and locations of all such devices shall be determined by the Planning Board, Police Chief, and Municipal Engineer and shall be in conformance with the Manual on Uniform Traffic Control Devices, as currently revised.
F.
Street lighting. The applicant shall coordinate with the appropriate servicing utility, the Road Commissioner, and the Police Chief for furnishing, locating and placing of any lighting. Light poles and luminaires shall be a type approved by the Planning Board and said utility.
G.
Walkways shall be provided along all roads within a proposed subdivision.
H.
Private ways.
(1)
A private way built to the "private residential" standards of this section shall not be accepted as a public way; provided, however, that privately owned roads in mobile home parks are exempt from the requirements set forth in this article but shall be considered as streets for building purposes. The plan shall contain a note which shall read: "The Town of Cumberland shall not be responsible for the maintenance, repair, plowing, or similar services for the private way shown on this plan."
(2)
If at a future date users of the road upgrade the private way to the standards set forth in this article, the users may petition the Town Council to consider the acceptance of the road as a public way.
