[Ord. No. 39-1998, ch. 2, 12-1-1998]
The subdivision ordinance, the definitions in section
66-1, the floodplain regulations (chapter
78, article
II), the site plan regulations (chapter
90), and the zoning regulations (chapter
102) shall be used as a supplement to this chapter. The following words, terms and phrases, when used in this chapter, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:
AASHTO
The American Association of State Highway and Transportation
Officials. Most guidelines for roadway design are from this organization.
ADT
Average daily traffic.
ADT PER RESIDENTIAL UNIT
ADT per residential unit equals 10 trips. Source: Table 3-1,
General Guide on Trip End Generation Rates by Land Use, Transportation
and Land Development, by Vergil G. Stover and Frank J. Koepke, published
by the Institute of Transportation Engineers.
BASE COURSE
The layers of select material (usually gravel) of designated
thickness placed on a subgrade to support a surface course.
BOND
A surety bond, or a form of security approved as to form
by the City manager and City attorney, which may include a letter
of credit or escrow account.
CITY ENGINEER
The City engineer may be a regular employee of the City or
a consultant to the City. The individual designated as City engineer
shall be a registered professional engineer, licensed by the state.
DEVELOPER
Any person, group of persons, organization, etc., whose concern
and desire is to improve land in accordance with the development regulations
of the City.
DEVELOPMENT
Any improvement done on any property which bears on the matters
covered in this chapter, and which triggers the need for approval
by the City, by way of regulation, rule, or ordinance of City, state
or federal government.
DRIVEWAY
A vehicular way that allows access onto private property
from a street. Driveways having over 80 ADT, or serving commercial
or industrial entities (home occupations and home occupation expanded
definition excluded), must be approved by the City engineer and the
City safety director. Driveways having 80 ADT and over or serving
commercial or industrial entities into parking lots are subject to
street standards regarding grade and drainage.
ITE
The Institute of Transportation Engineers. The organization
publishes a reference handbook entitled Traffic Engineering Handbook,
current edition.
FRONT YARD
A yard between the front line of the principal structure
and the front line of the lot and existing the full width of the lot
as it abuts along a public or private street.
MDOT SPECIFICATIONS
State of Maine Department of Transportation Standard Specifications,
Highways and Bridges, current revision.
PAVEMENT STRUCTURE
The combination of subbase, base course and surface course
placed on a subgrade to support the traffic load and distribute it
to the street bed.
PRIVATE WAY
A way totally owned by the entities being served. It can
be a driveway, or it can be a street or lane, subject to the applicable
standards.
RESERVE OR SPITE STRIP
Any land along a right-of-way located for the purpose of preventing development of abutting land through deprivation of required frontage or control of access to the right-of-way. See the subdivision ordinance, the site plan regulations (chapter
90) and the zoning regulations (chapter
102).
RIGHT-OF-WAY
A general term denoting land, property or interest therein,
usually a strip, acquired for or devoted to a street or road.
ROAD
A general term denoting a public or private way for purposes of vehicular travel, including the entire area within the right-of-way. For the purpose of this chapter, the term "road" shall refer to non-development and rurally located public and private ways, usually of rural design. See the zoning regulations (chapter
102).
SIDEWALK
That portion of the street primarily constructed for the
use of pedestrians, also called pedestrian way.
SLOPES
A side slope is the downward slope adjacent to the shoulder
(or sidewalk) of the road, which may go to a ditch or original ground.
A backslope is the upward slope to original ground on the other side
of a ditch (or shoulder in case of a ledge cut).
STREET
A general term denoting a public way for the purpose of vehicular
travel. This includes all of the right-of-way, and any other easements
or fee, dedicated to that purpose. In regard to this chapter, the
term "street" shall refer to the design and development of all public
and private ways, whether rural or urban. For the City, the factors
in classifying streets concern access to property, mobility, and traffic
volume. This chapter will not consider development of arterials or
freeways, as they involve other funding and would be subject to standards
other than City standards. The classification of streets, in ascending
order, is as follows:
(1)
Driveway. A driveway is usually privately owned and not a named
street. In its general usage, it has the lowest traffic volume of
this grouping, and allows interior access to property. See the definition
of "driveway."
(2)
Local street. A local street provides exterior access to adjacent land, such that vehicles travel short distances and connections are made to other streets. In regard to this chapter, local streets may be an urban lane (see figure 1 in section
98-85), a rural lane (see figure 1A in section
98-85), or a residential street (see figure 2 in section
98-85).
(3)
Collector street. A collector street serves as an intracity travel corridor, channelizing and distributing traffic to and from arterials and collector streets, in addition to providing exterior access to property. Residential collectors have an ADT range of 900 to 3,000. See figure 3 in section
98-85.
(4)
Industrial and commercial street. Industrial and commercial streets provide access to lots in commercial, business, and professional areas. See figure 4 in section
98-85.
The street and lane summary in section 98-85 provides a matrix comparison of the design requirements for these streets.

SUBGRADE
The top surface of a street bed upon which the select material
is placed, usually original ground or common fill material.
SURFACE COURSE
One or more layers of pavement designated to accommodate
the traffic load. The top layer may be called the wearing course.
The bottom layer may be called the binder course or pavement base
course.
TURNAROUNDS INVOLVING DRIVEWAYS
All drives must have the ability for the using vehicle to
turn around, or to pass directly through. One-unit residential drives
are exempt from this provision. Parking lots for cars are considered
to function as a turnaround as result of handicap spaces and the number
of spaces required. Commercial driveways and parking lots involving
truck usage must provide proper geometry to turn the truck around.
The use of AASHTO turning templates is required for truck (more than
two axles) usage, and is to be shown on the plan.
UNPAVED WAY
Any driveway having over 80 ADT or serving commercial or industrial entities (home occupations and home occupation expanded definition excluded) must be paved. Any unpaved driveway must be maintained in compliance with chapter
102, article
IX. The use of modern fabric grids or other methods in base material is a permissible design. The engineering design data is to be submitted for review, all subject to approval by the City engineer.
WALKWAY
A pedestrian way other than street sidewalk.
