Part I
Street and Roadway Design Criteria
Section 1
Street and Roadway Classification
1.01 General
Augusta-Richmond County Planning Commission shall determine street/road
classifications for all new developments or substantial changes or improvements to
existing developments. These classifications shall be based on the following definitions
utilizing Average Daily Traffic (ADT) information, The ADT will be determined using
the Institute of Traffic Engineers (ITE) Trip Generation manual, current edition.
Minor or Residential Streets - Streets that provide access to frontage properties and are
designed to carry traffic having origins or destinations within the immediate area
traversed. Such streets are not designed to interconnect adjoining neighborhoods,
subdivisions, or non-residential areas. They should be designed so that no segment has
an ADT greater than 500. A loop street may be considered two separate streets but the
design ADT at any point shall not exceed 500.
Residential Collector Streets - The highest order of residential street. Conducts and
distributes traffic between lower-order residential streets and higher-order streets (arterial
or expressways). Such streets function to promote free traffic flow; therefore, curb
parking should be prohibited and special setbacks and/or lot widths should be required,
Residential collectors should be designed to prevent use by non-neighborhood traffic.
Total traffic volume should not exceed 3,000 ADT.
Collector Streets - Streets that connect minor or residential streets to higher order streets,
either collectors or arterials. Such streets function to promote free traffic flow, therefore
curb parking should be prohibited and special building setbacks and/or lot widths should
be required. Collectors should be designed so as not to be attractive as shortcuts for
traffic that has neither an origin nor destination within a neighborhood or an immediate
area traversed. Residential collectors should have sidewalks on at least one side.
Collector streets should be designed to accommodate a maximum ADT of3,000.
Arterial Streets - Higher order, interregional streets that convey traffic between centers.
There should be no curb parking and ideally there would be limitations on access to
frontage properties. Most traffic would not have origins or destinations within the
immediate area traversed,
Section 2
Right-ofway Requirements
2.01 General
Right-of-way requirements shall be established based on roadway classification and the
proposed geometry of the pavement section, Because design requirements and proposed
concepts vary for each proposed project, cross-sectional roadway geometry will vary to
provide for the installation of curb and gutter or conversely, shoulders and ditch sections,
3
;J .
The following right-of-way requirements and pavement widths have been established for
each roadway classification:
PROPOSED ROADWAY REOUIREMENTS
CLASSIFICATION MINIMUM CURB & GUTTER SHOULDER & DITCH SECTION
DESIGN
SPEED Right-of- Pavement Width Right-of- Pavement Shoulder
Way B/C to B/C Way Width Width
Minor 25 60 31 80 24 6
Residential 30 60 31 80 24 6
Residential CoIlector* 35 80/60 31 80 24 6
Collector 35 80 31 80 24 6
Industrial Access 35 80 31 80 28 6
Arterial** 45 100 53 120 48 8
*Residential Collector streets shall require an 80 foot right-ofway on theftrst 200 feet of the proposed
residential collector street from major intersections, The right-of way may be reduced to 60 feet for those
portions of a residential collector street between major intersections beyond the 200 feet requirement.
**Georgia DOT Standard Specifications Type 7 curb and gutter shall be required where speeds
are 45 mph or greater.
2.02. Intersections
Right-of-ways at intersections shall include a "mitered" configuration. The mitered right-
of-way would be established by reducing the property line a total length of twenty-five
(25) feet along each right-of-way line from the intersecting point of two (2) right-of-way
lines. Connecting the two (2) right-of-way lines at the twenty-five (25) feet distance will
create the "mitered" configuration. "Clear View" easements shall not be accepted.
On all corner lots, there shall be provided a sight area easement. This easement shall be
that triangle formed by the lines beginning at the point of intersection of the centerIines
of the intersecting streets and extended sixty feet along each centerline for a distance of
sicty feet, and a line connecting the points represented by the end of these lines. Within
this easement no structure, earth, vegetation, or other obstruction shall be allowed which
is more than 2 Yz feet in height above the finished centerline grade on the road.
Driveways and parking stalls are also prohibited from encroachment of the sight area
easement. This may be increased upon recommendation of the Traffic Engineer. In liew
of providing a sight area easement, the developer may show said areas as part of the
street right-of-way. Supporting data shall be shown on the plans,
Section 3
Layout Requirements
3.01 Vertical Ali~nment:
· The minimum centerline grade for roadways shall be maintained at 0.5% for cross-
sections utilizing concrete curb and gutter; all others shall be at least 1 %.
4
, '
) -.
· The maximum centerline grade for roadways shall be maintained at 15 percent. In
the event that specific site conditions necessitate the design ofroadways in excess of
15 percent, the Augusta-Richmond County Planning Commission along with the City
Engineer shall review and consider an exception, It shall be handled on a case-by-
case basis.
· Street and intersecting street approaches shall not have grades in excess of 5% for a
distance of fifty (50) feet from the intersection of centerlines in all directions for all
streets,
· At roadway intersections with normal crown, a vertical curve is required to tie into
the grade of the intersecting street. The vertical curve shall be designed with the
extension of the cross slope of the through road as the first tangent and the approach
grade of the intersecting street as the second tangent.
· The vertical curve tying into an intersecting street with a through street shall not tie
into the edge of the pavement of the through street, but shall maintain at least a 15,0
foot tangent distance from the edge of pavement to the PVT.
· All intersections shall be designed to avoid cumulation of water.
· Vertical curves at intersections shall be designed to accommodate a minimum two car
stacking distance.
· The minimum length of a vertical curve through the run of the road shall be 130 feet;
the minimum length of a vertical curve used to accommodate an intersection design
shall be 50 feet.
· The minimum stopping sight distance shall be established based on design speed
limits in accordance with AASHTO design criteria. The minimum stopping sight
distance shall govern the length of vertical curve, but in no case shall the minimum
length of vertical curve be less than 130 feet.
· Excepting minor classified streets, a minimum 30-mph design speed limit should be
utilized unless otherwise noted and agreed upon by the Augusta-Richmond County
Planning Commission or Traffic Engineering. A minimum design speed of 25 mph
should be utilized for minor streets. Design exceptions may be granted on a case-by-
case basis as approved by City Engineer, Augusta-Richmond County Planning
Commission and Traffic Engineer.
3.02 Horizontal Ali{!nment
.
The maximum length of any dead-end./cul-de-sac street shall be 1,000 feet. The
Augusta-Richmond County Planning and Zoning Commission will review special
condi tions necessitating the installation of a roadway in excess of 1,000 feet.
Exceptions to this policy shall be granted on a case-by-case basis.
All permanent dead-end streets shall be provided at the closed end with a turn-around
having a street-property line diameter of not less than eighty (80) feet. Turn-arounds
of this nature shall have a paved diameter of not less than sixty (60) feet. Dead-end
streets intended to be continued at a later time shall be provided with the same turn-
around as required for a permanent dead-end street, but only that portion to be
required as right-of-way when the street is continued shall be dedicated and made a
public street.
Minor and residential roadways should be laid out to avoid long tangent sections and
to discourage speeding and cut-through traffic. New techniques in the layout of
residential developments that discourages speeding may be approved on a case-by-
.
.

1 .
case basis with specific design requirements governed and approved by the Augusta-
Richmond Planning Commission, Public Works and Traffic Engineer,
· Minimum tangent requirements for horizontal curves will be based on roadway
classification in accordance with the following table:
Road Classification Length of Tangent
(feet)
Minor 60
Residential 75
Residential Collector 100
Collector 125
Arterial AASHTO
Typically, residential streets will not require superelevation design if posted speed limits and
calculations are based on a speed limit of 30 mph or less. For speeds in excess of 30 mph on
collector and arterial roadways, superelevation cross-sections shall be requiredfor horizontal
curves.
.
For minor and residential streets with posted speed limits less than or equal to 30
mph, the tangent distance required between reverse curves shall be based on the
minimum stopping sight distance requirements.
Reverse curves are discouraged in the design of roadways. However, topographic
and design characteristics may dictate the need for reverse curves. Reverse curves
will only be allowed on minor and residential road classifications. Should speed
limits dictate the use of superelevation horizontal curve design, the transition zone
required to achieve superelevation will establish the tangent length between reverse
curves.
When submitted for review by the City Engineer and Traffic Engineer, plans and
construction drawings shall include the road classifications in accordance with
Planning and Zoning requirements. Classifications shall be clearly labeled on each
road/street.
The minimum allowable distance between the centerlines of streets intersecting a
common roadway shall be established by the minimum stopping sight distance, In
the event that development of property along existing right-of-ways necessitates a
roadway intersection without the appropriate stopping sight distance between
intersecting street centerlines, the City Engineer and Traffic Engineer will review
the available data and consider permit exceptions.
Connecting an existing street to a proposed street with non-parallel centerlines will
be allowed for streets with posted speed limits less than 30 mph, The connection of
the two streets shall result in a centerline deflection of less than 10 degrees.
Centerlines that connect at deflections greater than 10 degrees will require the
design and installation of a horizontal curve in accordance with road classification
requirements.
Minor and residential street intersections shall be designed with a minimum 25 foot
radius on each intersecting corner, All roadways that intersect collector, arterial or
state highways will require a minimum 30 foot radius on each intersection corner.
Intersection of streets shall maintain a 90-degree angle, Design exceptions may be
granted on a case-by-case basis as approved by the City Engineer and Traffic
Engineer.

5.01 General:
Each public street and road shall be paved or surfaced with a paving or surfacing of a
type and strength deemed suitable for the volume and character of traffic to be expected.
No street or road shall be provided with less than a paved (asphalt or concrete) all
weather surface. The type of roadway surfacing shall be determined by the Department
of Public Works and Engineering except where the proposed roadway is on a part ofthe
existing system of state highways, Public Works and Engineering shall first consult with
the Georgia Department of Transportation over such portion of the state system for its
recommendation.
Due to the geologic location of Augusta-Richmond County along the Fall Line,
separating the Coastal Plains Geologic Province from the Piedmont Province, the Georgia
Department of Transportation Standard Specifications for Construction allow the use of
sand-clay in the construction of roadway base course (Section 303). Although sand-clay
and graded aggregate are acceptable materials to be utilized in the development of base
and sub-base construction, Augusta-Richmond County encourages graded aggregate base
constructi on.

sub grade stabilization prior to base construction,
5.03 Base:
All base course design and construction shall be accomplished in accordance with
Georgia Department of Transportation Standard Specifications, current edition.
7
inches of compacted graded aggregate base will be required in accordance with Georgia
Department of Transportation Standard Specifications.
Complete pavement analysis and design data may be required by the City Engineer to
establish minimum rigid and flexible pavement system components. Base thickness shall
not be less than the minimum established for minor and residential roads.
On roadway cross-sections without curb and gutter, the base material shall be extended at
least six (6) inches beyond the limits ofthe asphaltic or concrete pavement on each side
of the road.
5.04 Pavement Criteria:

asphalt curb shall not be installed on top of existing asphalt pavement (Appendix).
· The tie-in of storm drainage structures installed on raised edge asphalt cross-sections
shall include concrete transitions as specified in the Augusta-Richmond County
Construction Standards (Appendix).
· In curb and gutter road sections, roadside slopes should be constructed to include a
shoulder of 8 feet from the face of curb.
· A minimum of one (1) foot extension of sidewalk grades shall be required behind the
sidewalk prior to establishing slopes. Site conditions should dictate actual slope
cross-sections for fill or cut slopes; a minimum fill section slope of two (2) horizontal
to one (1) vertical is desirable. A minimum cut cross-section slope of two (2)
horizontal to one (1) vertical is desirable.
· Concrete "rolled curb" may be allowed in certain residential developments. The
application for utilizing concrete rolled curb will require prior approval by the City
Engineer. The approval process will include hydraulic and road spread calculations
to establish the safety of rolled curb for the specific application. All rolled curb shall

classifications. The minimum length of deceleration lanes is 150 feet.
· Deceleration lanes shall be constructed to provide a minimum 12 foot travel lane and
total pavement width of 14.5 feet to the back of curb. In the event that curb and
gutter is not used, the asphalt width shall be 12.5 feet with an appropriate shoulder in
accordance with the road classification requirements.
· Exceptions for the requirement of a deceleration lane shall be considered by the City
Engineer and Traffic Engineer on a case-by-case basis. Exceptions shall be based on
projected traffic generation, through street traffic counts, and accident analysis in the
area.
· Acceleration lanes shall not be required. In lieu of an acceleration lane, a 50-foot
taper shall be installed from the end ofthe radius of the intersecting street to the
arterial or collector road. The Traffic Engineer shall determine specific radius and
lane taper.

8.02 Commercial Developments:
Large developments, greater than 200,000 square feet of building area, shall provide a
traffic impact study to determine required roadway improvements. Required
improvements shall be established by the Traffic Engineer and may include but is not
limited to left turn lanes, signalization, deceleration lanes, concrete curb and gutter, etc.
Section 9
Driveways
9.01 General:
Individual driveways may be required on all residential properties and commercial
properties. Depending on the design and construction of the public roadway system,
various pavement cross-sectional structures may be used including roadside shoulders
and ditches, concrete curb and gutter, and raised asphalt sections. Additionally, materials
of construction utilized to establish the access driveways may vary.
9.02 Residential Drives:
· For concrete curb and gutter roadway cross-sections, driveways may be extended to
the edge-of-pavement utilizing a typical Georgia Department of Transportation valley
gutter section. The concrete curb and gutter may be removed on both sides of the
intersecting driveway to the nearest full joint or construction joint of concrete curb
and gutter. This curbing shall be replaced in the construction of the new driveway in
accordance with Georgia Department of Transportation Specifications.
· An alternate drive construction technique is allowable for concrete curb and gutter
roadway sections in accordance with the following criteria. The curb shall be saw cut
at the end of the radius of the proposed driveway. The existing gutter shall remain
intact. A new concrete lip shall be constructed 1.5 inches above the gutter line
extending from the gutter to the back of curb. The driveway concrete apron shall be
installed to back of the newly constructed 1.5 inch concrete lip at back of curb with
appropriate expansion joint.
· For raised edge asphalt pavement cross-sections, driveways shall be constructed to
the back of the raised edge asphalt without disturbing the structural integrity of the
pavement system, including the raised edge asphalt. Grading activities to install the
drive shall be accomplished to avoid damage to the base or sub grade supporting the
pavement system and the raised edge asphalt.
· For roadway cross-sections with shoulders and longitudinal ditch sections, driveways
shall be installed with a culvert capable of handling the projected stormwater runoff
through the longitudinal ditch. Appropriate design calculations sizing the culvert will
be required. Flared end sections and/or concrete headwalls, in accordance with
Georgia Department of Transportation Specifications, shall be required. All
headwalls shall be located to meet clear zone requirements as established by the
AASHTO Roadside Design guide. Changes in alignment of longitudinal ditch
sections to meet clear zone requirements are subject to approval by the City Engineer
10
based on appropriate hydrologylhydraulic calculations. In addition to end treatments,
culverts shall require appropriate soil and erosion control measures to control velocity
entering and leaving the culvert section and protect the longitudinal ditch section
from erosion, siltation or degradation. All disturbed areas within the right-of-way,
including the longitudinal ditch section and shoulders shall be revegetated
appropriately.
Driveways constructed over longitudinal ditch sections shall require a minimum 8 foot
travel surface with 2 foot shoulders on each side of the travel way. Minimum slope
dimensions for the embankment construction shall be 3 horizontal to I vertical.
Longitudinal culverts under the drive shall be sized to allow appropriate end treatment
(and tied into the driveway embankment). Material types in accordance with Georgia
Department of Transportation Standard Specifications shall be utilized.
9.03 Commercial Driveways:
· All commercial driveways shall be installed in accordance with Georgia Department
of Transportation Standard Specifications. All commercial drives tying into varied
roadway cross-sections as described for residential driveways shall be treated
similarly. The location and width of all commercial drives shall be subject to the
approval of the City Engineer and Traffic Engineer.
· A curb cut shall be located as far as practical from the intersection of the right-of-way
lines of two streets, and no curb cut shall be permitted within fifty (50) feet of an
intersection. Each parcel that is in ownership separate from the ownership of
contiguous parcels shall be entitled to at least one curb cut per street front. Except in
single family residential zones, curb cuts shall be at least 100 feet apart where
practical. Except in single family residential zones, shared driveways are encouraged,
and where practical a driveway that is not a shared driveway shall be at least fifty (50)
feet from a property line.
· Owners/developers of commercial developments accessing county roadways utilizing
existing driveway cuts shall be required to submit development plans indicating on-
site traffic movement and site ingress and egress to the City Engineer and Traffic
Engineer for review and approval. The owner may be required to improve the
driveway cut to accommodate the proposed development or eliminate the existing
drive.
Section 10 Miscellaneous Elements
10.01 On-street Parkine:
On-street parking along commercial corridors is allowed in certain areas of the urban
district. On-street parking will be evaluated on a case-by-case basis by the City Engineer
and Traffic Engineer.
On-street parking will not be allowed on collector streets and/or arterial roadways. On-
street parking along residential collector streets shall be evaluated by the City Engineer
11
and Traffic Engineer. On-street parking is generally allowed on residential and minor

Part IV
Maintenance
General:
The construction of roadway systems and streets within our county are of particular concern to
the Augusta-Richmond County Commission-Council. Proper design, construction and
maintenance ofthese facilities require a responsibility on the part of the developer/contractor to
construct cost effective yet structurally sound transportation corridors that may be accepted into
the County roadway system. Once accepted, these facilities become the responsibility of the tax
payer to maintain.
In general, maintenance requirements vary for various types of construction and treatment.
Therefore, temporary maintenance agreements are required for those properties dedicated to
Augusta-Richmond County Commission for maintenance and ownership while private and
commercial development are responsible, independently for the maintenance and efficient
operation of facilities developed for these proj ects.
Section 1
Commercial Development
Owners of commercial developments are responsible for all aspects of traffic ingress/egress to
commercial facilities. Augusta-Richmond County assumes no responsibility or liability for the
operation, maintenance, and care of these systems. In the event that deterioration of systems
encroaching public right-of-ways at access locations to County maintained roads, minimum
levels of maintenance to insure the safety of motorist, pedestrians, and other forms of vehicular
transportation are required. Therefore, Augusta-Richmond County Commission reserves the
right to require improvements to these facilities within the right-of-way in the event structures
are not adequately maintained.
Section 2
Subdivision Development with Public Right-ofways
During the developer maintenance period, the developer and/or contractor shall be responsible
for all routine, remedial and/or capital improvements required to insure that the roadway system
and associated storm drainage facilities effectively operate within the parameters established
during design.
Following the developer maintenance period, and after public rights-of-way and easements are
dedicated to and accepted by the Augusta-Richmond County Commission, routine maintenance
and capital improvement activities shall be the responsibility of the County.
Section 3
Private Subdivision Developments
Private subdivisions may be designed and developed in accordance with sound engineering
practices and specifications that have not been adopted by Augusta-Richmond County
Commission for acceptance into the county infrastructure system. All private subdivisions not
designed, constructed, inspected, and approved in accordance with the minimum standards
established by Augusta-Richmond County can n.Q.t be accepted into the county infrastructure
system for ownership and maintenance. Therefore, it is the responsibility of the property
owner(s) to maintain all facilities in accordance with design requirements. This responsibility

shall include the necessary periodic and regular maintenance as required to insure the efficient
operation of the system. Capital improvements may be required in the event of system
deterioration or ineffective operation of the facility based on approved plans.
Final plats of privately developed subdivisions shall include the following statement identifying
the property owner(s) responsibility for maintenance of the roadway system in perpetuity:
"The streets, roads and stormwater management facilities are the private
property oJ the owner, who has Jull and perpetual responsibility Jor their
maintenance and repair. The owner releases Augusta-Richmond County
Commission from any and all claims, damages, or demands arising on
account oJ design, construction, ownership and maintenance of the streets
and roads as shown hereon. The Augusta-Richmond County Commission
assume no liability or duty related thereto, and in no manner approves or
assumes liability Jor the design of the streets and road as shown hereon. "
Private subdivisions not constructed in accordance with the standards and specifications setforth
by Augusta-Richmond County Commission may not be inspected during construction activities.
Consequently, these developments and associated infrastructure can not be accepted into
Augusta infrastructure system for ownership and maintenance.
