3.0 PERMIT REOUIRED
3.1
GENERAL: No person shall construct, reconstruct, relocate or in any way alter the
design or operation of any driveway without a building or approach permit issued by the
Chief Building Official. No work shall be undertaken on a driveway until the executed
permit has been received by the applicant. In no event shall a driveway be allowed or
permitted if it is determined by the Director to be detrimental to the public health, safety
and welfare.
3.2 APPLICABILITY: Driveway permits shall be issued only in compliance with this
ordinance and may include terms and conditions authorized by the ordinance.
3.3
STREET RECONSTRUCTION: Where in the course of public street reconstruction by
the City, County or State of Texas it becomes necessary to revise an existing driveway to
protect public health, safety and welfare, the property owner shall be notified in writing
of the required changes. Said changes shall be implemented at the cost of the appropriate
public agency, and will not result in denial of reasonable access from the property to the
general street system.
3.4 TRAFFIC IMPACT ANALYSIS REQUIRED: For commercial, service or mnlti-family
driveways on a major street facility or collector or local street, the Applicant shall submit
a Traffic Impact Analysis as part of the permit application and review process if the
number of parking spaces serviced by the driveway exceeds 100 spaces per driveway or if
-5
the driveway is projected to serve 1000 or more vehicles per day or 100 ingress vehicles
in the design hour.
3.5 COMMON ACCESS: Lots with sufficient frontage to safely meet the design
requirements of Section 5.0 may be permitted their own driveways. A common access
easement may be required between adjacent lots fronting on a major street facility or
collector or local street in order to minimize the total number of access points along those
streets and to facilitate traffic flow between lots.
The owner or developer of property required to use common driveways shall be
responsible for obtaining easements on adjacent property as necessary. The City may,
but shall not be required to, assist in the acquisition of off-site easements if the owner is
unable to acquire them. With a request for assistance, the owner shall provide the City
with documentation of his efforts, including evidence of a reasonable offer made to the
adjacent property owner. Upon such a written request for assistance, the City may
attempt to acquire these easements through negotiations. If the negotiations are
unsuccessful, a request may be submitted to Council for consideration of acquisition
through condemnation or a request may be submitted for consideration of a temporary
drive in accordance with Section 6.2 if the adjacent property has not developed. If the
applicant choses to pursue an off-site easement, the total cost of the acquisition and the
cost of the easements shall be paid by the owner (developer). If the applicant choses to
pursue a temporary drive, the owner (developer) shall be responsible for the cost of the
temporary drive and shall provide f'mancial security to remove the temporary drive and
replace or repair the street as needed upon development of the adjacent property. In the
event the City elects not to acquire the property through condemnation, alternate
driveway locations and designs shall be required in conformance with tiffs ordinance.
4.0 REVISION OF EXISTINQ DRIVEWAYS FOR CONFORMANCE
Upon application for building permit or certificate of occupancy, existing driveways that are
not in conformance with this ordinance shall be brought into compliance at the expense of the
Applicant as a condition of the building permit or certificate of occupancy if one of the
following conditions exists:
a. The existing use of the driveway is projected to increase in actual or proposed daily
design hour volume by twenty (20) percent or more.
The change in the use of the property or modifications to the property restricts the flow of
vehicles entering or exiting the property in a manner which is anticipated to disrupt
normal traffic flow in the public street, thereby creating a hazard. Change in property use
may include but is not necessarily limited to change in type of business, expansion in an
existing business, change in zoning, and subdivision which creates new parcels. It does
not include modifications in advertising, landscaping, remodeling, general maintenance,
or aesthetics that do not affect internal or external traffic flow or safety.

TABLE ONE NOTES:
The requirements for Driveway Throat Width and Driveway Curb Radius are for standard undivided two-way
operation and may be varied by the Director if traffic volumes, truck usage, common driveways, and other
factom warrant such.
The minimum centerline spacing does not implicitly determine the number of driveways allowed. Driveways
served by deceleration lanes may be spaced at closer intervals if approved by the Director. See Section 5.2('0)
for additional restrictions on driveway locations along S.H. 114 frontage roads.
Distance measured from the intersecting R.O.W. line to the centerline of the driveway. See Section 5.2Co) for
additional restrictions on driveway locations along S.H. 114 fi'ontage roads.
Service driveway centerline spacing may be reduced to 150' if the ingress/egress volume is less than 50 vehicles
per day and if the service driveway is a secondary driveway ancillary to a commercial driveway within the
same development.
· The minimum centerline spacing may be reduced to 250' provided that the driveway is connecting directly to a
frontage road and provided that it meets the criteria in Section 5.2('o).
Refer to Section 5.2(c). Commercial, multi-family and service driveways may not be permitted on collector or
local streets.
The minimum centerline spacing may be reduced to 250' for right-in/right-out driveways. Refer to Section
5.2(a).
5.2 GENERAL DESIGN CRITERIA
DRIVEWAYS ON F.M. 1709, F.M. 1938 & INTERSECTING ARTERIALS:
The minimum eenterline spacing for full-access driveways on F.M. 1709 & F.M.
1938 is 500 feet as per Table One; however, the minimum centerline spacing may
be reduced to 250 feet for right-in/right-out driveways in accordance with
Appendix 1: Driveways constructed within 250 feet of an intersection of F.M.
1709 or F.M. 1938 and an arterial shall be right-in/right-out only. All right-
in/fight-out drives shall be designed in accordance with Appendix 5 and shall
have signs placed at the Applicants expense indicating right turn in only facing
the street and right turn out only facing the property.
DRIVEWAYS ON S.H. 114: Driveways along S.H. 114 (and its future frontage
roads) shall be designed in accordance with Texas Department of Transportation
(TxDOT) access control guidelines as applicable to the conceptual design and
a|i~ments of the proposed reconstruction of S.H. 114. Driveways will be not be
allowed within areas indicated as "access denied" as per Appendices 2 & 3.
Co
DRIVEWAYS PROHIBITED: Commercial, multi-family and service driveways
shall not be permitted on collector or local streets unless the tract or lot has no
other public access. In the event there is no other public access, commercial,
multi-family and service driveways shall be permitted on collector or local sta'eets
provided that they meet the design standards in Section 5.1.
REQUIRED INTERNAL STORAGE (STACKING / MINIMUM THROAT
LENGTH): The driveway for any multi-family, commercial or industrial property
that connects to a major street facility or collector or local street shall extend onto
private property a minimum distance of 10 feet, but not less than the required
front bufferyard width, from the right-of-way line before intersecting any internal
circulation drive. Internal storage (stacking) shall be provided on multi-family,
commercial or industrial properties for corresponding driveways in accordance
with Table Two for driveways that provide ingress/egress to parking areas of 20
or greater spaces.

driveways are not included in the calculation.)
~tte total number of parking spaces is the stun of all spaces accessible by a driveway or
driveways both on-site and off-site.
The internal storage shall be separated from parking areas by a raised curb island
or median with a back-of-curb to back-of-curb width equal to the minimum
storage length divided by 25 or 3 feet, whichever is greater. Planting
requirements for the island or median shall be in accordance with Sections 3.4(b)
and 3.5 of the Landscape Ordinance No. 544, excluding the requirements for
canopy trees. Appropriate signage (e.g. stop, yield, etc.) shall be placed for any
vehicular cross movement or internal circulation that intersects the ingress/egress
circulation beyond the required internal storage.
10-
COMMON ACCESS EASEMENTS: The use of common driveways shall require
the dedication of a joint-use private access easement on each affected property.
Said dedication shall be provided on the final plat of the subject properties, or be
filed by separate instrument with Tan'ant County with a copy forwarded to the
City.
The common access easement shall encompass the entire width of the planned
driveway plus an additional width of one foot (1') on both sides of the drive. At a
minimum, the size of the aeeess easement must be twelve (12') feet wide and
fifteen (15') feet deep for residential driveways or twenty-six (26') feet wide and
forty-two (42') feet deep for commercial and service driveways. When the center
of the easement is offset from the common lot line, the easement must~ extend past
the lot line a minimum distance of one (1) foot.
RADIUS RETURN LIMIT: For any driveway, the point of radius return tangency
with the street curb shall not extend beyond the property line (projected
perpendicular to the street centerline) except as provided in common driveway
agreements and as approved by the Director.
g. CURB LEAVE-OUTS: Ifa street curb is to be left out for later installation of a
driveway, the driveway shall be poured within six (6) months of the issuance of
the permit, or the curb shall be replaced.
UTILITY OFFSET MINIMUM: No portion of any driveway shall be located
within four (4') feet of any fire hydrant, electrical pole, or any other surface public
utility. The Applicant, at his expense, may have the surface utility moved, if the

OFF-STREET MANEUVERING: All vehicle maneuvering on multi-family,
commercial, and industrial properties into a parking space or up to a loading dock
or into any other area shall be accomplished by off-street maneuvering areas and
internal driveways. No back-in or back-out vehicle maneuvering from a driveway
shall be allowed to occur on any public street or right-of-way with the exception
of residential drives on local streets.
ADEQUATE SIGHT DISTANCE: Driveways shall be prohibited where adequate
sight distance is not available for the established speed limit Sight distances shall
be calculated in accordance with the latest edition of the AASHTO "A Policy on
Geometric Design of Highways and Streets." Ifa field inspection indicates that
driveway sight distance may be insufficient, the Applicant will be required to
submit vertical and horizontal information prepared by a registered Professional
Engineer to the City Engineer that verifies adequate sight distance is available for
the proposed driveway location.
SITE PLAN REQUIRED: A site plan showing all existing right-of-way,
easements, curbs, storm drain inlets, flmes, underground and overhead utilities,
trees and sidewalks shall be required for each non-residential driveway permit
application. The proposed driveway grades shall also be shown for a minimum
distance of fifteen (15') feet past the right-of-way line. All driveways and median

access easement shall also be required as described in Section 3.5. Shared
residential driveways may be required for adjoining residential lots on major
street facilities to reduce the number of access points on those roadways.
ACCESS TO MAJOR STREET FACILITY: Driveway access to a residential lot
from any major street facility shall not be permitted unless that lot has no other
public access. If such a driveway is approved on a major street facility, an off-
street maneuvering area approved by the Director shall be provided to ensure that
vehicles will not back into the public street. Driveway access to a residential lot
from a collector street may be denied if either (a) the lot has access to a local
street or (b) the proposed access would create a traffm flow or safety problem
unless there is no other access.
5.4 AUXILIARY LANES
WHEN REQUIRED: As a condition of a Driveway Permit, the Applicant shall
provide a deceleration lane for any driveway located on an arterial sweet if the
right mm ingress volume exceeds 50 vehicles in the design hour (150 vehicles if
the design hour occurs on a Sunday). If the existing or future speed limit on the
street faciliW exceeds 40 MPH, a deceleration lane may be required if40 right
Co
do
turn ingress vehicles occur in the design hour (100 vehicles if the design hour
occurs on a Sunday).
DRiVEWAYS PROHIBITED: No driveway shall be permitted within the
transition area of any separate right turn or deceleration lane.
EXTENSION OF RIGHT TURN LANE: When a driveway is approved within
the separate right mm lane ora public street intersection, the lane shall be
extended a minimum of fifty (50') feet in advance of the driveway.
CONTINUOUS DECELERATION LANE: A continuous deceleration lane may
be required as a condition of a driveway permit when two or more deceleration
lanes are planned and their proximity necessitates that they be combin0d for
proper traffic flow and safety. The transition taper for a continuous deceleration
lane shall not extend into or beyond a public street intersection.
LEFT TURN LANES ON UNDIVIDED ROADS: On undivided arterial
roadways, a left mm lane and taper may be required as a condition of the
driveway permit when the product of the projected left mm ingress volume (50
minimum) and the opposing volume per lane exceeds 25,000 in any design hour.
In such cases, a Traffic Impact Analysis shall be provided by the Applicant to
analyze the present and future traffic volumes to verify that the left turn lane is
necessary to maintain minimum levels of traffic flow and safety.
LEFT TURN LANES ON DIVIDED ROADS: On divided arterial roadways, the
Applicant shall, as a condition of the permit, construct a left turn lane at an
existing public street median opening when the proposed driveway will be served
by such median opening and no left turn lane exists in the median.
g. TEMPORARY AUXILIARY LANE: The Director may requke a temporary
attxiliary lane to be constructed on existing arterial roadways that are planned for
future improvement.
h. DECELERATION LANE EXTENSION: In the event the Applicant is allowed to
locate a driveway connecting to a deceleration lane within one hundred (100!) feet
of an arterial intersection, the Applicant shall be required to extend the
deceleration lane to such intersection. The one hundred (100') feet shall be
measured from the nearest edge of the driveway throat to the nearest R.O.W. line
of the intersecting arterial.
CONSTRUCTION COSTS: The Applicant shall be responsible for the design,
right-of-way adjustment of utilities, and construction costs of any auxiliary lane
and street widening required as a condition of the driveway permit. If for any
reason an auxiliary lane required under this Ordinance cannot be constructed in
conjunction with the driveway by the Applicant, the Applicant may be required to
place all necessary funds in escrow with the City.

5.5 SIGNALIZED DRIVEWAYS
DRIVEWAY INTERSECTION SIGNAL ANALYSIS: As a condition of a
driveway permit on a major street facility, the Applicant shall submit driveway
volume and capacity information when signalization is requested at the driveway
intersection. Signals shall not be installed unless one or more signal warrants are
met as per the most recent edition of the MUTCD (Manual on Uniform Traffic
Control Devices) and unless the study indicates the installation of a traffic signal
will improve the overall safety and/or operation of the driveway intemection. If a
signalized driveway is constructed on F.M. 1709, F.M. 1938, or on the S.H. 114
or the frontage roads of S.H. 114, it shall be no less than 1000 feet from any
adjacent signalized driveway or signalized public street intersection.
SIGNAL CONSTRUCTION: If the driveway analysis indicates a signal is
required and an overall public benefit is shown, the Director may require as a
condition of the permit that the Applicant pay for the traffic signal installation
costs necessary to serve the subject driveway.
SIGNAL RECONF1GURATION COSTS: Ifa driveway is permitted and installed
at an existing signalized intersection, the Applicant shall pay any costs necessary
to modify the existing signal to acconunodate the new driveway.
5.6 SPECIAL DRIVEWAY DESIGNS
HIGH VOLUME DRIVES: The Director shall require the Applicant to submit a
Traffic Impact Analysis for any driveway on a major street facility or collector or
local street projected to serve 1,000 or more vehicles per day, or 100 ingress
vehicles in the design hour. Based on the need created by such driveway, the
Director may require internal driveway improvements, turning movement
prohibitions, auxiliary lanes, and traffic control devices to address safety and/or
capacity problems with the property which may have a detrimental effect on the
adjacent public street system.
LEFT TURN EGRESS CONTROL MEDIAN: All driveways on undivided
arterial roadways having a projected exiting left mm volume that will operate at a
level-of-service "E" or worse as defined in the Thoroughfare Plan may be required
to be c0nstmcted with a left mm egress control median. Likewise, any driveway
having a projected ingress left mm volume that will have a level-of-service "E" or
worse as defined in the Thoroughfare Plan may be required to have a left turn
ingress control median. If the level of service for both left mm ingress and left
turn egress are projected to be at a level-of-service "E" or worse as defmed in the
Thoroughfare Plan, a right in/right out driveway design shall be required.
-14-
5.7 DRAINAGE DESIGN: In the vicinity of existing or future drainage structures, no
driveway shall be permitted which may impair the effectiveness of the existing drainage
facilities. Drainage in side ditches shall not be significantly altered or impeded by any
driveway.
6.0 CONSTRUCTION STANDARDS
6. I DRAINAGE:
ESTATE SECTIONS (streets without curb and gutter): When drainage structures
are required, the dimensions of the culvert or opening and other design features,
such as slope, capacity of structure, drainage computations and amount of flow,
necessary grading upstream and downstream information, and section treatment
and similar information on any upstream and downstream structures shall be
shown on a site plan and accepted by the City Engineer. A minimum (smooth
flow) pipe size of an eighteen inch (18") diameter shall be required. The
restricted areas (defined in Section 7.1) adjacent to the driveways may be filled in
or graded, provided they are in compliance with the requirements herein.
CULVERT DESIGN: The drainage structure shall have a minimum
capacity of a five (5) year frequency event (and preferably a 25 year or 100
year), unless an analysis is submitted by the applicant that demonstrates
the bar ditch capacity on both sides of the proposed installation is less.
The City Engineer may, based on the results of this analysis, allow a
culvert with less capacity. In addition, grading of the upstream and/or
downstream side ditches may be required to allow the proposed drainage
system to function as designed. Proper provisions shall be made for
surface drainage, so that all surface water on any filled area shall be
carded over the drive and drainage structure by means of a swale
(minimum eighteen inches (18") unless otherwise approved) and in
accordance with the natural drainage patterns.
REQUIRED HEADWALL: The drainage system undemeath the filled
area shall have sloped end sections six feet (6') horizontal to one foot (1')
vertical with necessary concrete rip-rap or TxDOT standard Type "A" or
"B" headwalls. This provision shall apply unless an alternate is requested
in writing and approved by the City Engineer.
CURB AND GUTTER STREETS: The surface of the driveway at the throat
(tangent point of the driveway radius to the edge of the driveway) shall be six (6")
inches or greater above the pavement at the outer line. Driveways shall not be
constructed at such locations or in such manner that water is diverted fi.om the
street onto private property.

no case will the standards be less than the following: 1. Ditch flows will not be impeded,
2. The entrance will allow access by emergency vehicles during all weather
conditions,
3. The entrance will not create adverse impacts on existing roadways,
4. The entrance shall be maintained during the life of the temporary facility.
In no cases will the use of a temporary driveway be permitted for a period longer than
120 days. In the event that an entrance is anticipated to be used for a longer period of
time specific permission will need to be obtained from the Director of Public Works.
6.3 PERMANENT DRIVEWAYS: Permanent driveways are any driveway intended for long
term usage. All construction shall conform with the City of Southlake Construction
Standards. In no case shall the thickness of the driveway approach be less than the

Any such curb or block shall be a minimum of six (6") inches wide, six (6") inches high,
and shall be permanently and securely anchored. The property owner shall replace any

the street right-of-way while being serviced, a greater distance may be required by the
Director.
7.4
MAINTENANCE AND RESERVATIONS: Maintenance of all driveways, islands, and
other driveway appurtenances within public right-of-way shall be the responsibility of the
Applicant prior to issuance of a certificate of occupancy after which the maintenance

changes, lnaintenances, and repairs shall be borne by the property owner.

8.1
MODIFICATIONS: Modifications may be granted by the Director for the particular area
of responsibility controlled by such official under unique circumstances whenever needed

provided that the modifications are in conformity with the intent and purpose of this
ordinance. The Director may defer any request by an applicant to the City Council for
final determination.
8.2 VARIANCES AND APPEALS: Any applicant who desires a variance or elimination of
the requirements herein, or who desires to appeal a decision of the Director regarding
modifications to this ordinance shall file a written appeal to the Director who shall place
the request on the agenda for consideration by the City Council. The City Council shall
have the authority to grant a variance to this ordinance. In granting any variance, the City
Council shall determine that a literal enforcement of the regulations herein will create an
unnecessary hardship or practical difficulty on the applicant, that the situation causing
urmeces~ary hardship or practical difficulty is unique to the affected property and is not
self-imposed, that the variance will not injure and will be wholly compatible with the use
and permitted development of adjacent properties, and that the granting of the variance
will be in harmony with the spirit and purpose of this ordinance. The decision of the City
Council shall be final.
