the proposed usage of land involved, the existing usage of land in the vicinity, the number of
persons who will reside or work in the proposed subdivision, and the probable effect of a such
variance on traffic conditions and public health, safety, convenience, and welfare of individuals
in the vicinity. No variances will be granted unless the council finds the following:
4�
(a) There are special circumstances or conditions affecting the land involved such that the
strict application of the provisions of the ordinance would deprive the applicant of the
reasonable use of his land.

other lands in the area in accordance with the provisions of this ordinance.
Pecuniary hardship to the subdivider, standing alone, shall not be deemed to constitute undue
hardship.
Any variance thus authorized is required to be entered in writing into the minutes of the

STREETS
All street improvements proposed for any subdivision to be developed under the jurisdiction of
these ordinances shall be fumished and installed by the subdivider in accordance with the
"Standard Specifications for Public Works Construction", published by the North Central Texas
Council of Governments (NCTCOG), latest edition.
The purpose of this section is to provide a set of minimum design standards to be used in the
designing of roadway facilities in the City of Anna. These guidelines will be used by consultants
employed by the city and engineers for private developments in the city. Each sheet of the
plans and profiles will bear the seal and signature of the registered professional civil engineer
who prepared them. These guidelines should result in the construction of safe, economical
streets and thoroughfares. The City Council may approve unusual circumstances or special
designs requiring a variance from the standards in this manual.
Classification of Roadways
There are four (4) basic classifications of streets in the City of Anna. The classifications are as
follows:
Principal Arterial seven (7) lane divided and undivided
This classification is designed to handle large volumes of intra- and inter -city travel through
Anna. No direct residential driveway access should be allowed (at least on new sections where
driveways do not presently exist).
Minor Arterial five (5) lane divided and undivided and Minor Arterial four (4) lane
undivided
This classification is designed to feed traffic from collectors and minor residential streets the
Principal Arterial. Direct residential driveway access should not be allowed on new sections of
arterial except where existing driveways are present.
Collector two (2) lane undivided
Collector streets should direct residential and local traffic onto the nearest arterial to avoid
carrying volumes of through -traffic across residential neighborhoods and other sensitive areas.
Direct residential driveway access is permitted. The Collector street shall be the minimum
street class serving commercial, industrial or multifamily areas.
Residential two (2) lane undivided
The minor residential is to provide access to the various residential classifications in the City of
Anna.
Each roadway is made up of elements that are related to the use of that particular facility.
These elements include right-of-way, pavement width, median width if required, arrangement of
traffic lanterns and parking tones, curb radii at intersections and other characteristics, Table No.
1 is to be used in the design of the various classifications of roadways in Anna.

Geometric Design
General
Geometrics of city streets may be defined as the geometry of the curbs or pavement areas,
which governs the movement of traffic within the confines of the rights-of-way. Included in the
geometrics are the pavement, width, radius of curvature, width of traffic lanes, parking lanes, or
turning lanes, median width separating opposing traffic lanes, median nose radii, curb radii at
street intersections, crown height, cross slope, geometric shapes of islands separating traffic
movements and other features. Since city streets are differentiated by their functions and
location, there is also a variance in the geometry which describes the path vehicular traffic
should follow.
Design Speed
The design speed is a primary factor in the horizontal and vertical alignment on city streets and
thoroughfares. Design features such as curvature, radii for turning movements and sight
distances are directly related to the design speed. The design speed also affects features such
as lane widths, pavement width, pavement cross -fall, pavement crown, and clearances.
The design speed is defined as the approximate speed that can be maintained safely by a
vehicle over a given section of road when conditions are so favorable that the design features of
40 the roadway govern. The speed limit or posted speed is the maximum legal speed set by local
Page 3 of 16
1-25-2000
i
The horizontal geometrics of the streets and thoroughfares include the segment of geometric
design associated with the alignment, inter -sections, pavement widths, and related geometric
elements. The various classifications, utilizing the design speed as a control, must have certain
horizontal and vertical geometrics to provide a safe economical facility for use by the public.
Horizontal Curves
The alignment of the streets and thoroughfares is usually determined by the alignment of the
existing right-of-way or structures which cannot be relocated. Changes in the direction of a
street or thoroughfare are minimized by constructing a simple curve having a radius that is
compatible with the speed of vehicular traffic.
Curvature in the alignment of arterials is allowed under certain conditions, but the greater traffic
volume and the higher vehicle speeds which accompany these thoroughfares tend to increase
the number of accidents when curving of alignment occurs. Curves in the alignment of
residential streets usually provide aesthetic value to residential neighborhoods without affecting
the orderly flow of traffic or safety. Minimum permitted radii of curvature are shown in Table No.
3. These are based on traffic consisting of typical present day automobiles operating under
optimum weather conditions. There are other important considerations in the design of curves
Page 4 of 16
1-25-2000
authorities for a certain roadway or area. The design speed should never be less than the likely
legal speed limit.
The various street and
thoroughfare classifications that make up the
system within the City
require different design
speeds according to their use and location. Table No. 2 indicates the
allowable design speeds for the various classifications within the City.
Lower design speeds
(and speed limits) may
be permitted for all classifications for unusual
conditions, terrain, or
alignment.

on thoroughfares including the location of intersecting streets, drives, bridges, and other
topographic features.

MINIMUM CENTERLINE RADIUS FOR ROADWAYS
Street Classification — Minimum Radius (FT)
i Arterial-- 40 mph 700 —�
LCollector-35 mph_ 500 {I
Residential -30 mph 300
Residential streets intersecting a collector street or arterial street will have a tangent section of
centerline at least fifty feet (50') in length measured from the right-of-way line of the collector or
arterial street. No such tangent is required when the residential street curve has a centerline
radius greater than four hundred feet (400') with the center located on the collector street or
major street right-of-way line.
Reverse circular curves shall be separated by a straight tangent section not less than one
hundred feet (100') long.
Turning Lanes
Turning lanes are provided at intersections to accommodate left -turning vehicles. The primary
purpose of these turning lanes is to provide storage for the turning vehicles. The secondary
purpose is to provide space to decelerate from the normal speed to a stopped position in
advance of the intersection or to a safe speed for the turn in case a stop is necessary. Left turn
lanes at intersections shall be twelve feet (12') in width (minimum). Turn lanes shall have a
width transition of not less than one hundred fifty feet (150') in length and a storage lane of not
less than one hundred fifty feet (150') in length.
Street Intersections
The intersection at grade of all thoroughfares will be at or near an angle of ninety degrees (900).
At the intersection of these thoroughfare types, the various geometrics including pavement
widths, lane widths, curb radii, median widths, tuming lane data, crossfall, crown height, and
other features differ. Streets often intersect at angles less than ninety degrees (90°); however,
no street will be allowed to intersect at less than seventy degrees (700). Table No. 4 shows the
curb radii required for intersections at ninety degrees.

The location of any median nose will be so located that traffic will clear it while making a left
turn. Other considerations include adequate clearance between the median nose and through
traffic on the intersecting thoroughfare and location of the median nose to properly clear the
pedestrian crosswalks.
Sidewalks
The purpose of the public sidewalk is to provide a safe area for pedestrians. The City of Anna
requires that sidewalks be constructed with the paving of streets or when building construction
occurs and that all sidewalks conform to state laws for barrier free construction.
Concrete sidewalks on residential streets will have a width of not less than four feet (4') and
thickness of not less than four inches (4") and will be constructed of three thousand pounds per
square inch (3,000 psi) concrete on both sides of all streets. Sidewalks will be constructed not
less than one foot (1') from the street right-of-way line and will extend along the street frontage
including the side lot corner lots and block ends.
Sidewalks on arterial streets and non-residential collectors shall be five feet (5') wide.
All concrete for sidewalks will be placed on a two-inch (2") sand cushion and will be reinforced
with 6 X 6 No. 6 gauge welded wire fabric or number three (3) reinforcing steel bars spaced at
eighteen inches (18") on center each way.
The subdivider may petition for a determination by the City that sidewalk construction is either
not feasible or inappropriate at the time of subdivision construction. If determined to by
inappropriate at the time of construction by the City, funds for such construction shall be placed
in escrow with the City by the subdivider. The sidewalk escrow rate will be approved by
resolution by the City Council.
Vertical Alignment
The vertical alignment of all thoroughfares should be designed to insure the safe operation of
vehicles by the traveling public and should allow easy access to adjacent property. A travel -
way, which is safe for vehicles, is dependent on criteria which considers operating speeds,
maximum grades, vertical curves, and sight distance. In addition to these considerations, other
factors related to vertical alignment include storm drainage inlet may also be required in the
median.
In presenting the grades of intersecting thoroughfares in the paving plans, profiles of all four (4)
curbs of a thoroughfare will be shown as a continuous grade through the intersection of the
other thoroughfare.
Minimum Grades
Minimum longitudinal grades for streets and thoroughfares are required to insure proper flow of
surface drainage toward inlets. Minimum grades are five -tenths percent (.5%) for Portland
cement and asphaltic concrete pavement. The minimum grades for cul-de-sacs will be six -
tenths percent (0.6%). All valley gutters should be a minimum of eight feet (8') wide and
• constructed of reinforced concrete and will have minimum grades of five -tenths percent (0.5%).

Maximum Grades
Maximum longitudinal grades will be compatible with the type of facility and the accompanying
characteristics including the design speed, traffic conditions and sight distance.
Arterials must move large volumes of traffic at faster speeds, and flatter grades will better
accommodate these characteristics. Truck and bus traffic on these type facilities often control
traffic movement, particularly if steep grades prevent normal speeds. The normal maximum
street grades allowed for Anna streets are shown in Table No. 5. Steeper grades may be
permitted for short lengths where required by topographical features or restricted alignment.

On undivided streets, the maximum difference in curb elevations will not exceed five -tenths foot
(0.5').
Vertical Curves
When two (2) longitudinal street grades intersect at a point of vertical intersection (PVI) and the
algebraic difference in the grades is one percent (1.0%) or greater, a vertical curve is required.
Vertical curves are utilized in roadway design to affect a gradual change between tangent
grades and should result in a design which is safe, comfortable in operation, pleasing in
appearance, and adequate for drainage. The vertical curve will be formed by a simple parabola
and may be a crest vertical curve or a sag vertical curve.
Stopping Sight Distance
Crest Vertical Curve
When a vertical curve is required, it must not interfere with the ability of drivers to see a length
of street ahead, should they be required to suddenly stop. This length of street, called the
stopping sight distance, should be sufficient length to enable a person in a vehicle having a
Page 7 of 16
1-25-2000
eye height of three and three quarters feet (3.75') above the pavement and traveling at or near
• design speed to stop before reaching an object in his path five tenths foot (0.5') in height.
The minimum stopping sight distance is the sum of two distances: 1) The distance traversed by
a vehicle from the instant the driver sights an object for which a stop is necessary to the instant
the brakes are applied; and 2) The distance required to stop the vehicle after the brake
application begins.
•
The minimum safe stopping sight distances for the City of Anna street types are shown in Table
No. 6. These sight distances are based on each design speed shown and on wet pavement.
The minimum length of crest vertical curve required for the safe stopping sight distance of each
street type may be calculated using the formula L = KA. The values of K for a crest vertical
curve are also shown in Table No. 6.

Sag Vertical Curve
When a sag vertical curve is required, the vertical curve will be of sufficient length to provide a
comfortable ride and safe stopping sight distance during the change in vertical direction. The
minimum length of sag vertical curve required shall be calculated using the formula L = KA and
the values of K for a sag vertical curve are shown in Table No. 6.
Intersection Grades
The grade of an intersecting street with the principal street gutter should not be generally more
than four percent (4%) either up or down within the first twenty feet (20') beyond the curb line of
the principal street except that in very hilly terrain a maximum intersecting grade of six percent
(6%) can be considered. Grade changes of one percent (1%) or more require vertical curves.
Median Openings
The following standards for median openings are established to facilitate traffic movement and
promote traffic safety.
Median openings will normally be permitted at all intersections with dedicated City of Anna
Streets. Exceptions would be at certain minor streets where, due to unusual conditions, a
hazardous situation would result. Normal spacing between median openings should be no
more than twelve hundred feet (1,200').
Mid -block median openings or other openings with left turns permitted into adjacent property will
not normally be permitted unless all the following conditions exist:
• The property to be served is a significant traffic generator with demonstrated or projected
trip generation of not less than two hundred fifty (250) vehicles in a twelve (12) -hour period.
• The median opening is not less than four hundred feet (400') from an intersection with an
arterial thoroughfare.
• The median opening is not less than two hundred sixty feet (260') from an intersection with
II t
a co ec or thoroughfare.
• The median opening is not less than three
proposed median opening.
Th
hundred feet (300') from any other existing or
• e median width is sufficient to permit the construction of a left turn storage lane.
• Median openings will not be permitted in left tum storage lanes, Wherever possible,
median openings should serve both sides of a thoroughfare.
Driveway and Curb Openings
The minimum distance between driveways is normally twenty feet (20'). The distance between
one-way, ninety -degree (900) drives can vary between four feet (4') and twenty feet (20'). The
island between angle drives should equal or exceed fifty square feet (50 S.F.) in area.
In all cases, driveway locations must conform to minimum safe sight distance and stopping sight
distance standards.
Page 9 of 16
1-25-2000
•
Driveway Grades
The normal driveway grade within the street right-of-way is one-quarter inch per foot rise above
the top of curb at the property line. The minimum elevation of a driveway at the right-of-way is
two inches (2") above the top of the curb. Barrier free sidewalk construction requires a
maximum driveway grade as measured from the gutter of eight percent (8%).
Where driveway construction or reconstruction must occur off the street right-of-way, the usual
maximum grade is fourteen percent (14%). The maximum change in grade without vertical
curve is twelve percent (12%) for any ten feet (10) in distance. Driveways should be profiled for
a distance of at least twenty-five feet (25) outside the right-of-way to ensure adequate
replacement design.
Due to state laws requiring barrier free construction of sidewalks, steps or other abrupt changes
in sidewalk grades are prohibited at driveways.
Alley Grades
Alleys are constructed with a 5 -inch inverted crown for drainage. The maximum grades for
alleys are eight percent (8%) within thirty feet (30') of an intersection with a street and fourteen
percent (14%) elsewhere, unless otherwise approved by the City, and the minimum grade is
four tenths percent (0.4%). Changes in grade, including intersections with streets, may not
exceed three percent (3%) without providing vertical curves.
Pavement Design
Factors which influence the performance of thoroughfare pavement include the subgrade upon
which the pavement structure rests, the quality of materials used to construct the pavement, and
the type and amount of traffic using the facility. In designing a pavement that will provide a
reasonable degree of performance during an expected life, certain factors can be
predetermined. The load bearing capacity of the subgrade will be determined by making a soils
engineering investigation of the site. The strength of the pavement can also be established by
specifications and quality control during construction.
Standard pavement sections are established in Table No. 10A, "Minimum Standard Concrete
Street Pavement Design" and Table 10B "Minimum Standard Asphalt Street Pavement Design".
Unusual design conditions may be encountered that will preclude the use of Table No. 10A or
10B. The proposed pavement will be designed in accordance with the geotechnical
investigation or Table No. 10A or 108, whichever is more restrictive.
