[Adopted 9-11-2006 by Ord. No. 3-2006; amended in its entirety 12-12-2016 by Ord. No. 12-2016 (Ch. 11, Art. I, of the 1976 Code)]
The purpose of this article is to:
A. 
Promote public health, safety and welfare of the residents of Winslow by establishing construction standards for public and private roads.
B. 
Establish minimum specifications for the design and construction of driveways and roads.
C. 
Ensure that safe and sufficient access is provided to all development within the Town.
D. 
Promote road durability and reasonable service life.
E. 
Establish minimum standards for traffic safety and the carrying capacity of roads.
These standards shall apply to all new and expanded public roads and driveways within the Town of Winslow that are designed, installed or constructed as of the effective date of these standards on September 11, 2006.
A. 
Provisions of safe and adequate access. All development, structures, and buildings located in the Town of Winslow shall have access to a public road. The type of access will vary, depending on the location and number of residential dwelling units. Commercial and other nonresidential access shall be designed based upon the estimated daily vehicular trips. Classifications are as follows.
(1) 
Private driveway (for residential use only). A private driveway may not serve more than two residential dwellings. It is intended for private access and is not eligible for public acceptance. Lots may be permitted only after the twenty-foot right-of-way is recorded at Kennebec County Registry of Deeds. Planning Board approval is required prior to construction.
(2) 
Common private driveway (for residential use only). A common private driveway may serve no more than four residential dwellings. Common driveways are intended to serve rear lot development and small housing clusters with limited potential for additional housing. They are not eligible for public acceptance. Lots may be permitted only after the thirty-five-foot right-of-way is recorded at Kennebec County Registry of Deeds. Planning Board approval is required prior to construction.
(3) 
Rural standard road. A rural standard road is designed to serve up to 40 residential dwelling units. This road design is intended for small to moderate-sized subdivisions and developments.
(4) 
Rural collector roads. A rural collector road is designed to serve developments of more than 40 residential dwellings. These roads are intended for use in major developments and as collector streets for other, smaller rural roads.
(5) 
Urban standard roads. An urban standard road is designed for up to 40 residential units in densely developed residential subdivisions within the MDOT Urban Compact Area. Curbs and gutters are required.
(6) 
Urban collector roads. An urban collector is designed to serve over 40 residential units in densely developed areas within the MDOT Urban Compact Area or streets serving multiple commercial establishments within the MDOT Urban Compact Area. Depending on traffic analyses, more than two traffic lanes, and turning lanes, may be required. Sidewalks, curbs and gutters are required. These roads serve as collector streets for other, smaller urban roads.
B. 
Commercial and nonresidential development. Driveways, parking lots and roads proposed to serve commercial and nonresidential developments shall be designed by a professional engineer and designed to serve the estimated daily vehicular trips for the proposed use.
C. 
Exceeding design category. Northing shall prevent a person from designing and building a road or driveway to a higher category than required by these standards.
D. 
Future upgrades. All roads and driveways constructed after the effective date of these standards may not serve new development that would exceed the dwelling unit design threshold of the road or driveway in which they were constructed, unless the road or driveway is expanded according to these standards.
E. 
Upgrades to existing roads. A road built prior to the effective date of these standards shall be upgraded in conformance with these standards whenever the existing road provides the only access for proposed development and would exceed the design threshold. The Planning Board may determine that an upgrade is not required, but only if the new development will also be served by another Town road or if the expansion makes a new connection to another Town road.
A. 
The Planning Board shall review applications for establishment of new or upgraded roads under this article or in conjunction with subdivision applications. The developer may not make field changes to engineered plans accepted by the Planning Board; construction must conform to accepted plans. If changes are necessary, the developer must present proposed changes to the Planning Board prior to continuing with construction.
B. 
The Planning Board shall evaluate the type of road selected by the applicant to ensure that the road will be capable of accommodating future development expansion. The Planning Board may vote to require a higher road classification and shall consider the following in making its determination:
(1) 
Whether the particular conditions of the site allow for future expansion.
(2) 
A phased built-out of the subdivision is proposed.
(3) 
The applicant owns or has retained land adjacent to the subdivision with future development potential.
(4) 
Land adjacent to the proposed subdivision is suitable for future development.
(5) 
The density, and anticipated traffic volume, of development accessing the road.
C. 
The applicant shall provide, to the Planning Board, detailed construction drawings showing a plan view, profile, and typical cross-section of the proposed road, and existing roads within 300 feet of any proposed intersection. The road plans shall be designed by a professional engineer. The plan view shall be at a scale of one inch equals no more than 50 feet. The vertical scale of the profile shall be one inch equals no more than five feet. The plans shall include the following information:
(1) 
Date, scale and north point indicating magnetic or true north.
(2) 
Intersections of the proposed road with existing roads.
(3) 
Roadway and right-of-way limits including edge of pavement, edge of shoulder, sidewalks and curbs.
(4) 
Kind, size, location, material, profile and cross-section of all existing and proposed drainage structures and their location with respect to existing and natural waterways and proposed drainageways.
(5) 
Complete curve data shall be indicated for all horizontal and vertical curves.
(6) 
Turning radii at all intersections.
(7) 
Center-line gradients.
(8) 
Size, type and locations of all existing and proposed overhead and underground utilities.
(9) 
Erosion control plan showing all temporary and permanent measures.
(10) 
Stormwater control plan for the roadway.
(11) 
Stamp and signature of the engineer.
D. 
Engineering waivers. Engineering alternatives for new or different materials and practices may be considered by the Planning Board, provided that the intent of these standards is not reduced. The applicant shall hire a professional engineer to provide the Planning Board with all necessary information, in order to determine the adequacy of the proposed alternative.
All driveways and common driveways shall be constructed to the following minimum standards:
A. 
General standards for driveways and common driveways:
(1) 
A driveway shall be considered a private way and shall be maintained by its owner or owners.
(2) 
A turnaround area shall be provided for every portion of the driveway in excess of 800 feet.
(3)
