A.
Intent of requiring minimum level of service.
1.
It is the intent of the UDC, along with the City's adopted Technical
Manuals, to define certain minimum requirements for Public Facilities,
including utilities, roadways, storm drainage, parks, and other facilities
determined by the City Council as necessary to protect or promote
the public health, safety, and welfare and to ensure the quality of
life currently enjoyed by the citizens of Bee Cave.
2.
It is the intent of this UDC that no Subdivision occurs unless,
and until, it provides for the minimum levels of service required
by the UDC.
3.
The Subdivider must dedicate, construct or upgrade required
Public Facilities to a capacity that meets Adequate Public Facilities
standards (see Section 2.1.4).
B.
Basis for minimum standards.
1.
For each category of Public Facilities, the City requires a
minimum standard of infrastructure based upon historic studies and
construction projects of the City and other cities, which the City
may publish and update from time to time in its Technical Manuals
(see Section 1.1.16).
2.
The minimum standards reflect the minimum Public Facilities
required to protect or promote the public health, safety, and welfare
and to ensure the quality of life currently enjoyed by the citizens
of Bee Cave.
3.
All Private Facilities must be designed to Public Facilities
standards.
C.
Applicability.
1.
Within this Section 2.5, the term "Subdivision" has the meaning
of both Subdivision and development, and the term "Subdivider" can
refer to a Subdivider, Developer, Property Owner, or applicant. If
any question of interpretation arises, the City will define a term
as it is defined in the UDC.
2.
These standards apply to any development listed in subsection
2.1.2.C, Requirement to Plat and Section 2.1.6, Platting in Extraterritorial
Jurisdiction (ETJ).
(Ordinance 475 adopted 6/28/22)
A.
The City requires that each Subdivision contribute a fair and proportional
share of the costs of providing Adequate Public Facilities, consistent
with TLGC Section 212.904.
B.
The City finds a direct correlation between increased demand on Public
Facilities created by new a Subdivision and the City's requirements
to dedicate public right-of-way and easements, and to construct a
fair and proportional share of Public Facilities.
C.
A fair and proportional share is the Subdivider's portion of the
costs of Public Facilities as determined by the City Engineer in conformance
with State Law, which may be satisfied through dedication of public
right-of-way or easements, the payment of fees, or payment of construction
costs.
D.
The intent of this Section 2.5 is to provide standards for construction
and dedication of Public Facilities that are roughly proportional
to the nature and extent of the impacts created by the proposed Subdivision
on Public Facilities, including roadway, storm drainage, or parks
systems.
E.
For appeals to the requirements of this Section 2.5, see Section
2.6.1 [2.6.2] Subdivision Proportionality Appeal for procedures.
(Ordinance 475 adopted 6/28/22)
A.
Services required. Land proposed for Subdivision in the City and
in the City's extraterritorial jurisdiction (ETJ) must provide Adequate
Public Facilities, including water facilities, wastewater facilities,
roadway and pedestrian facilities, drainage facilities, and park and
open space facilities.
B.
Adequate public facilities not exclusive to city-owned facilities.
The term "Adequate Public Facilities" may refer to any Public or Private
Facility, which may be owned by the City or another public or private
entity, so long as the facility is designed, constructed, and maintained
to the standards of the UDC and the City's Technical Manuals.
C.
Approval timing. The City will not approve a Subdivision unless the
Subdivider provides adequate public facilities.
(Ordinance 475 adopted 6/28/22)
A.
Design and construction of Public Facilities must conform to the
standards, criteria, and requirements of the following, as they may
from time to time be amended by those responsible for their promulgation.
1.
The City's Thoroughfare Plan;
2.
The Texas Uniform Traffic Control Device Manual;
3.
American Association of State Highway Transportation Officials
Design Manual;
4.
Texas Health Code;
5.
The City's Engineering Criteria Manual;

7.
All other codes and ordinances of the City.
(Ordinance 475 adopted 6/28/22)
A.
Lot design.
1.
Lot design shall provide adequate width, depth, and shape to
provide open area, to eliminate overcrowding, and to be appropriate
for the type of development and use contemplated, and shall meet the
requirements of the Zoning Regulations of the City.
2.
Figure 2.5.5-1: Lot Types is provided for illustrative purposes
only and is not intended to represent examples of conforming lots
under this UDC.

B.
Lot frontage requirement. Every lot shall have frontage on, and access
to, a public street or private street (including alleys) meeting right-of-way
standards (see Section 3.4.1, Dimensional Standards for frontage requirements).
C.
Lot frontage restrictions for single-family lots on arterial and
collector streets. Single-Family Residential lots shall not have direct
access to any street classified as an Arterial Street, Neighborhood
Collector or Primary Collector. Direct access to a Residential Collector
Street shall be at the City Engineer's discretion.
D.
Right angles for side lot lines. All side lines of lots shall be
at approximately right angles to straight street lines and radial
to curved street lines except where a variation to this rule will
provide an improved street and lot layout, as determined by the City
Engineer.
E.
Through lots, reverse corner lots, and flag lots.
1.
Through Lots and Reverse Corner Lots are prohibited except where
essential to provide separation of residential development from traffic
arteries or to overcome specific disadvantages of topography and orientation.
2.
Through Lots require front setbacks on both frontages established
in accordance with the underlying Zoning Regulations.
3.
Proposed Through Lots meeting the criteria of this subsection
2.5.5.E may be approved by waiver (see Section 2.6, Subdivision Relief
Procedures).
4.
Flag Lots are prohibited.
F.
Lots with septic tanks. If a Subdivider wishes to serve buildings
in a Subdivision with septic service, the size of lots the septic
will serve must be large enough to provide drainage fields which meet
the County and State standards for septic service.
G.
Land subject to a 100-year flood.
1.
Any land that, in its natural state, is subject to a 100-year flood (i.e. base flood) or which cannot be properly drained shall not be subdivided, re-subdivided or developed until the Subdivider demonstrates that the construction of specific site drainage improvements will yield a usable building site per the minimum lot size standards of the zoning district, i.e., Flood Study and FEMA CLOMR (Conditional Letter of Map Revision) and in conformance with Section 6.5 [Article 7] Stormwater Management.
2.
If, after the completion of site drainage improvements, the Subdivision will yield a usable building site, as required in subsection 2.5.5.G.1, the Planning and Zoning Commission may approve a Subdivision Plat in conformance with all requirements of this Article 2. However, occupancy of a building is prohibited until the specific site drainage improvements have been planned, construction completed, and a LOMR (Letter of Map Revision) issued by FEMA.
H.
Variances for lots under common ownership.
1.
The Planning Director may approve variances to the standards
in this subsection 2.5.5 for lots intended to function under common
property ownership if the lots are dedicated on a Final Plat for the
use, ownership, and management of a Property Owners' or Homeowners'
Association as described in subsection 2.5.7.
2.
Condominium development, on a legal lot of record, may divide
property in a manner consistent with the UDC, subsection 2.5.7, Property
Owners' Associations, and Texas Property Code Chapter 82.
(Ordinance 475 adopted 6/28/22)
A.
Block measurement.
3.
Block measurement factors. the length, width, and shapes of
blocks shall be determined with due regard to:
(i)
Provision of adequate building sites suitable to the special
needs of the type of use contemplated;
(ii)
Zoning requirements as to lot sizes and dimensions;
(iii)
Needs for convenient access, circulation, control
and safety of vehicle and pedestrian traffic;
(iv)
Limitations of topography; and
(v)
Compatibility with efficient development of Public Facilities
as established by surrounding development.
|
Figure 2.5.6-1: Block Measurements
|
|
B.
Block length.
1.
Nonresidential block length. Block length in Nonresidential
Zoning Districts shall not exceed eight hundred (800) feet or ten
(10) times the minimum lot width permitted in that district, whichever
is greater.
2.
Mixed-use block length. Block length in the Mixed-Use zoning
districts (MU-N; MU-C; MU-TC) shall not exceed six hundred (600) feet
in length.
3.
High density residential block length. Block length in the Transitional
Residential (R-3) District, Urban Residential (R-4) District and Multifamily
Residential (R-5) District shall not exceed six hundred (600) feet.
4.
Low density residential block length.
(i)
Block length in the other Residential Zoning Districts and in
the ETJ shall be between two hundred (200) and eight hundred (800)
feet or 12 lots, whichever is less.
(ii)
If residential lots back up to a commercial use,
drainage area, or to an Arterial roadway, then there is no restriction
on the block length or the maximum number of lots, subject to the
Subdivision meeting the requirements of subsection 2.5.10, Access
Management.
(1)
If the residential lots back up to a commercial
use, the Subdivision must provide at least one (1) pedestrian walkway
to connect the commercial lots to the residential lots, unless the
City Engineer determines a connection is impractical. The walkway
may be gated to prevent two-way access.
(2)
Where residential development faces both sides
of a street, the required block length and restriction on the number
of lots along the block applies to the opposite side of the residential
street, including stubbed-out streets.
5.
In cases where physical barriers, adjacent development, or property
ownership, including dedication, ownership, and management by a Property
Owners' or Homeowners' Association (see subsection 2.5.7, Property
Owners' Associations) creates conditions justifying one or more variances
to the standards of this subsection 2.5.5 [2.5.6], the Planning Director
may administratively approve a waiver to meet existing conditions,
having due regard for connecting streets, circulation of traffic,
and public safety.
(Ordinance 475 adopted 6/28/22)
A.
Applicability. When a Subdivision contains one or more Common Areas
or other improvements not intended for dedication to the City for
public use, a Property Owners' Association shall be created through
a declaration establishing the duties and responsibilities, consistent
with state law.
B.
Dedication. The Common Areas shall be shown on the Final Plat along
with an adequate form for dedication thereof.
1.
This dedication form shall save the title to Common Areas for
the benefit of the Property Owners' Association; and
2.
The Subdivider shall convey the Common Areas to the Property
Owners' Association by filing a declaration and restrictive covenants
and providing a copy of such documents to the City (see subsection
2.5.7.F.5), and reference the documents by note on the face of the
Plat.
C.
Membership. A Property Owners' Association is an incorporated nonprofit
organization operating under recorded land declarations through which:
1.
Each lot owner in a described land area is automatically a member;
and
2.
Each lot is automatically subject to a charge for a proportionate
share of the expenses for the Property Owners' Association's activities,
such as maintenance of Common Areas, including common open spaces,
private streets, stormwater infrastructure, ponds, recreational facilities,
and the provision and upkeep of the same.
D.
Legal requirements. To ensure the establishment of a permanent Property
Owners' Association, including its financing and the rights and responsibilities
of the homeowners in relation to the use, management and ownership
of Common Areas, the Subdivision Plat, dedication documents, covenants,
and other recorded legal agreements must:
1.
Legally create an automatic membership, nonprofit Property Owners'
Association;
2.
Place title to the Common Areas in the Property Owners' Association
or give definite assurance that it automatically will be so placed
within a reasonable and defined time;
3.
Appropriately limit the uses of the Common Areas;
4.
Give each lot owner the right to the use and enjoyment of the
Common Areas;
5.
Place responsibility for operation and maintenance of the Common
Areas or Property in with the Property Owners' Association;
6.
Provide for or place an association charge or assessment on
each lot in a manner that will ensure sufficient Association funds
to maintain the Common Area and facilities;
7.
Give each lot owner voting rights in the Association; and
8.
Identify the land area within the Association's jurisdiction
including, but not limited to, the following:
(i)
The property intended for transfer to the City, PUA, or other
public agency;
(ii)
All properties or divisions of property or buildings
(such as townhomes or condos) intended for private ownership;
(iii)
The Common Areas to be transferred by the Developer,
Builder, or Subdivider to the Property Owners' Association.
E.
Private covenants. Private Covenants or Restrictions that assign
responsibility to the Property Owners' Association for the maintenance
and operation of all common property, and include provisions for assessments
enforceable by lien shall be developed.
F.
Procedure. Prior to or concurrent with the submittal of a Final Plat,
the Developer, Builder, or Subdivider shall:
1.
Draft the articles of incorporation of the Property Owners'
Association, its bylaws, and the covenants;
2.
Submit draft articles, bylaws, and covenants to the Planning
Director for approval;
3.
After approval, create an incorporated nonprofit corporation;
4.
Record approved covenants, at the County Clerk's office, which
will automatically make every property owner a member of the Association,
give the owners the right to use the Common Areas, and establish voting
rights and obligations to pay assessments;
5.
Provide a copy of the recorded articles, bylaws, and the restrictive
covenants prior to Final Plat approval; and
6.
Pay attorney fees for document review.
G.
Maintenance, repair, or capital improvement. Any maintenance, repair,
or capital improvement effort made to Property Owners' Association
property or facilities by the City as a result of non-performance
or negligence on the part of the Association shall be assessed between
the various Association members in proportion to the taxable value
of their properties.
(Ordinance 475 adopted 6/28/22)
A.
Sidewalks required. Sidewalks and Pedestrian Way are required as
a part of Subdivision approval to help the City achieve the following:
1.
Promote the mobility, health, safety, and welfare of residents,
property owners, and visitors to the City and to implement objectives
and strategies of the Comprehensive Plan.
2.
Improve the safety of walking by providing separation from motorized
transportation and improving travel surfaces for pedestrians.
3.
Improve public welfare by providing an alternate means of access
to transportation and social interaction, especially for children,
other citizens without personal vehicles, or those with disabilities.
4.
Facilitate walking as a means of physical activity recognized
as an important provider of health benefits.
B.
Path easements required. Properties adjacent to Bee Cave Parkway,
SH-71, FM 3238, RM 2244, and RM 620 are not required to construct
sidewalks adjacent to the highway but must dedicate a path easement
within the required landscape buffer parallel to the roadway.
C.
Sidewalk location, design, and construction.
1.
Sidewalks must be constructed for both sides of all streets
within a Subdivision.
2.
Sidewalks must be constructed along all lots adjoining public
or private streets, along Arterial streets where lots do not adjoin
the street, across power line easements, and in other areas where
pedestrian walkways are necessary.
3.
Routing to clear poles, trees or other obstacles is subject
to City Engineer approval.
4.
The Subdivision Construction Plans must show the location of
all proposed sidewalks and state at what stage of the project they
will be constructed.
5.
Sidewalks will be installed abutting the Public Right-of-Way
line unless the City Engineer approves an alternate location in writing.
6.
Public sidewalks constructed on private property (i.e., those
that meander from the Public Right-of-Way by design or necessity)
must have access through a pedestrian access easement recorded with
the Final Plat.
7.
At least five (5) feet of grass or other permeable ground is
provided between the roadway and sidewalk, unless the City Engineer
determines this is not feasible through a written determination.
8.
Sidewalk construction in front of lots may be delayed until
the development of those lots, but in locations not adjacent to lots
such as across bridges and culverts or open space lots, the sidewalk
must be constructed with the other improvements to the Subdivision.
9.
All sidewalks shall conform to Federal Americans with Disabilities
Act (ADA) requirements and barrier-free ramps must be provided wherever
a sidewalk intersects a public or private street or commercial driveway.
(Ordinance 475 adopted 6/28/22)
A.
Purpose. The purpose of this section is to ensure adequate and safe
pedestrian and vehicle circulation within the City and ETJ, and into
adjoining areas.
B.
General.
1.
Every Subdivision must be accessed by a public street, and each
lot or unit within the Subdivision must have access to a public street
or a private street that meets City standards and provides access
to a public street through the Subdivision.
2.
Gated subdivisions are not permitted within the City limits
or ETJ, except for single-family residential subdivisions with lots
one acre or greater in size, in which case gating of roads is permitted
under the following conditions:
(i)
Gating does not impede the current or future roadway connections
depicted in the City's adopted Thoroughfare Plan;
(ii)
Roads are privately owned and maintained pursuant
to Section 2.5.7;
(iii)
The method to be used to ensure City and emergency
access into the subdivision shall be approved by applicable emergency
services district. If the association fails to maintain reliable access
as required herein, the City may enter the subdivision and remove
any gate or device which is a barrier to access at the sole expense
of the association. The association documents shall contain provisions
in conformity with this Section which may not be amended without the
written consent of the City Council. Any private street which has
an access control gate or cross arm must have a minimum uninterrupted
pavement width of twenty-two feet (22') at the location of the gate
or access control device, both ingress point and egress point, regardless
of the type of device used. If an overhead, or lift-up, barrier is
used, it must be a minimum of fourteen feet (14') in height above
the road surface, and this clearance height shall be extended for
a minimum distance of fifty feet (50') in front of and behind the
location of the device. All gates and cross arms must be of a breakaway
design. A minimum vehicle stacking distance of one hundred feet (100')
shall be provided from the right-of-way line of the public road from
which the private street subdivision is accessed to the first vehicle
stopping point, which is usually an access request keypad or telephone
or a guard's window. Adequate distance shall be provided between the
access request point(s) and the entry barrier, or gate, to accommodate
a vehicle turnaround as described below.
(iv)
A paved turnaround space must be located in front
of any restricted access entrance barrier, between the access request
device and the barrier or gate, to allow vehicles that are denied
access to safely exit onto public streets without having to back up,
particularly into the public street upon which the entrance is located.
The design and geometry of such turnaround shall be of such pavement
width and having such inside turning radius that it will accommodate
smooth, single-motion U-turn movements by the following types of vehicles:
(1)
Larger passenger vehicles, such as vans and pickup
trucks;
(2)
Passenger vehicles with short trailers up to twenty-four
feet (24') in length, such as small flatbed, camping or box-type trailers;
and
(3)
The types of service and utility trucks that typically
visit or make deliveries to neighborhoods that are similar to the
proposed private street development, such as utility service vehicles,
postal and delivery trucks, and two- to three-axle flatbed or box-type
trucks used by contractors and moving companies.
3.
All Subdivisions must provide for streets and sidewalks to serve
the Subdivision in accordance with requirements included or referenced
in this Section 2.5.
4.
The Subdivider shall pay for, or, by Improvement Agreement,
participate in the cost to construct all roadways, public or private,
within or adjacent to the Subdivision, other than Arterials (see subsection
2.5.2, Rough Proportionality and Fair Share Policy Statement).
5.
The Subdivider is responsible for the cost of dedicating public
right-of-way and Public Facilities, including streets, in accordance
with the policies and standards of this Section 2.5.
6.
Additional public right-of-way may be required at some street
intersections to accommodate utilities, sidewalks, traffic control
devices, or sight distances, as determined by the City Engineer with
reference to a particular standard of the UDC or the City's adopted
Technical Manuals.
7.
See Section 5.1.2, Fencing and Screening Standards for fence
requirements related to lots backing to Arterial or Collector roadways.
C.
Street classification and design.
1.
Street classifications shall be as defined in the adopted Thoroughfare
Plan.
2.
All streets shall conform to the construction criteria contained
in the Engineering Criteria Manual.
3.
The City may prescribe vertical or horizontal geometric design
features to streets to facilitate bike and pedestrian traffic and
to slow auto traffic in areas intended for bike and pedestrian traffic.
These features may include speed tables, chicanes, curbs, drive aprons,
or other measures as approved by the City Engineer.
D.
Street layout.
1.
The Subdivider will coordinate and connect the Subdivision's
street system with existing future streets in the surrounding area,
consistent with the City's adopted Thoroughfare Plan.
2.
New streets created by the Subdivision shall connect to streets
in each adjacent Subdivision for the direct and convenient movement
of traffic between properties and Subdivisions.
3.
Where an existing residential Subdivision or property abuts
the proposed Subdivision, a street connection between the two properties
must occur at least every nine hundred (900) feet, or in alignment
with abutting Subdivision streets along each boundary of the Subdivision.
4.
Intersections and offsets.
(i)
Streets must intersect at safe and convenient locations at ninety
(90) degree angles. When ninety (90) degree angles are not possible,
the City Engineer may approve a skewed intersection. Skewed Intersections
should in no case have an angle less than 80 degrees or greater than
100 degrees.
(ii)
All proposed median openings will be spaced according
to the design criteria in the City's Technical Manuals, unless otherwise
approved by the City Engineer, or TxDOT as applicable.
(iii)
The spacing between curves and intersections
shall be in accordance with the City's Technical Manuals, unless the
City Engineer determines that no other practicable alternative exists.
5.
Stub-outs and cul-de-sacs.
(i)
Stub-out streets must be provided for connections to future
development.
(1)
If no development occurs and a stub-out street
is to be terminated, the Subdivider is responsible for creating a
permanent turnaround at the street that meets the City's standards.
(2)
The Subdivider must provide a temporary turnaround
for any stub-out street that exceeds one hundred and fifty (150) feet
in length from the nearest intersection. Dimensions are subject to
the adopted Fire Code.
(ii)
A cul-de-sac street must be platted and constructed
with a concrete cul-de-sac at the closed end having a turnaround with
a large enough radius to accommodate fire access.
(iii)
The maximum length of a Cul-de-sac or dead-end
street is three hundred (300) feet in length, unless the City Engineer
approves a greater length after determining no alternative layout
is practical.
6.
"Knuckle" street corners.

(i)
The minimum centerline
radius for the knuckle is fifty (50) feet;
(ii)
From the point of intersection of the centerlines
of the street sections leading into the turn, the minimum radius to
the right-of-way is fifty (50) feet and the minimum radius to the
edge of pavement is forty (40) feet;
(iii)
The minimum return radius of the knuckle is twenty-five
(25) feet; and
(iv)
The interior angle of the knuckle may not be less
than eighty (80) degrees or more than one hundred (100) degrees.

Access must be to a Collector Street or larger facility.
3.
Access points will be calculated by the total number of lots
shown on the Preliminary Plat.
4.
The Planning and Zoning Commission may require additional access
points if the configuration, number of lots, or other consideration
creates the need for additional access.
5.
In case of a conflict between this subsection 2.5.9.E and the
adopted Fire Code, the most restrictive standard applies.
F.
Street names and signs.
1.
Streets will be named to provide continuity with existing streets.
Names of new streets must comply with Section [Article] 16.05 of the
Code of Ordinances.
2.
Street signs will be furnished and installed by the Subdivider
for all intersections within or abutting the Subdivision.
3.
Such signs shall be of a type approved by the City.
4.
The Subdivider is responsible for installing street signs and
street marking in compliance with requirements set forth in the Technical
Manuals and the most recent edition of the Texas Manual on Uniform
Traffic Control Devices.
5.
All lots on which construction is proposed must have direct
access to a named street dedicated to the City or referenced on a
Final Plat.
6.
A Private Street must be named on a Final Plat if it provides
the only direct access to two (2) or more lots.
G.
Alleys. Unless explicitly required, alleys are optional improvements
and may be constructed at the discretion of the Subdivider. If alleys
are constructed, they must meet the regulations of this subsection
2.5.9.G and be in a separate lot(s) dedicated to and maintained by
a Property Owners' Association.
1.
Reinforced concrete or asphalt construction. Alleys must be
paved with reinforced concrete or asphalt with concrete curbing.
2.
Alley fences. Where a driveway connects to an alley, a fence
may be constructed along the rear lot line to a point within five
(5) feet of the intersection of the driveway and the alley.
3.
Alley right-of-way width and design. Minimum alley right-of-way
width and design will conform with the City's Technical Manuals.
4.
Intersections at right angles. Alleys shall intersect streets
at right angles or radially to curved streets.
5.
Intersections at arterial streets prohibited. Alleys shall not
intersect Arterial Streets.
6.
Dead-end alleys. The Subdivider must construct alleys with adequate
turnaround facilities meeting the standards in subsection 2.5.9.D.4
[2.5.9.D.5].
7.
Access. If an alley is the sole point of access to a particular
lot, the alley must meet minimum fire access requirements.
8.
Drainage conveyance. If the surface or subsurface area under
an alley is to be utilized for the conveyance of drainage from multiple
lots, the Subdivider must design and install proper drainage structures
and place them within drainage easements.
H.
Street right-of-way dedication. Any Subdivision with new streets,
existing streets, or adjacency to existing streets must dedicate sufficient
public right-of-way in accordance with the following regulations.
1.
General dedication requirements.
(i)
Travis County right-of-way.
(1)
Per agreement between Travis County and the City
of Bee Cave, all new developments in the ETJ must dedicate public
right-of-way pursuant to the Travis County Transportation Plan or
Bee Cave's Thoroughfare Plan.
(2)
If there is a difference in the width required
in the Travis County Plan and the Bee Cave Plan, the width of the
dedication must meet the wider requirement.
(ii)
Right-of-way alignment. The required alignment
of the public right-of-way is determined with respect to property
boundaries, safety, design, topography, and traffic management consideration.
(1)
Principles of efficient traffic management will
be applied in accordance with the City's goals and objectives as expressed
in the current Comprehensive Plan, including but not limited to the
Thoroughfare Plan.
(2)
The appropriate alignment of any public right-of-way
will be determined by examining the property and topographical conditions
along the entire length of the street.
(3)
In order to provide adequate information to establish
appropriate public right-of-way alignment, the Subdivider must provide
a survey showing property and topographical information for a minimum
distance of two hundred (200) feet in every direction that the street
extends from the property.
2.
New streets. The Subdivider will provide streets where there
is not an existing street, roadway, or passage.
(i)
The City's adopted Technical Manuals will determine the design
of internal streets.
(ii)
Perimeter streets.
(1)
When a Subdivision develops that abuts an existing
or planned Arterial Street or Collector Street, the Subdivider must
dedicate enough public right-of-way within the Subdivision to accommodate
the future build-out of the Arterial or Collector Street.
(2)
The Subdivider must construct their proportional
share of the abutting street and its appurtenances (such as curbs
and gutters, sidewalks, barrier-free ramps, street trees, etc.) to
the City's standards for the applicable street type (see subsection
2.4.4, Improvement Agreements and Fiscal Security).
(3)
The Subdivider's proportional share of the street
construction is determined by the City Engineer and is roughly proportional
to the impact the Subdivision causes on the street system (see subsection
2.5.2, Rough Proportionality and Fair Share Policy Statement).
(4)
If the Subdivider disagrees with the City Engineer's
determination of rough proportionality, then the Subdivider may file
a Subdivision Proportionality Appeal (see subsection 2.6.1 [2.6.2],
Subdivision Proportionality Appeal).
3.
Existing streets. If the existing geometric configuration of
a street does not accommodate the standards of the Technical Manual,
the City may require the dedication of additional public right-of-way
to address safety, design, topography, and traffic management considerations.
(i)
Adjacent to a platted subdivision.
(ii)
Along a right-of-way described by a metes and
bounds or a general written description.
(1)
The right-of-way dedication is based on the geometric
centerline of the right-of-way as described.
(2)
Reasonable geometric adjustments will be made to
accommodate safety, design, topography, and traffic management considerations.
(3)
All existing right-of-way dedications within the
Subdivision must be converted from "separate instrument" to a platted
right-of-way on the Final Plat.
(iii)
Along a prescriptive right-of-way.
(1)
The right-of-way dedication is based on the apparent
centerline of the existing pavement or of the travel way if unpaved.
(2)
Reasonable geometric adjustments will be made to
accommodate safety, design, topography, and traffic management considerations.
(3)
The Subdivider must indicate on the Preliminary
Plat and, if required, on the Final Plat any property lines and features
that identify the prescriptive right-of-way. Features may include
fences, borrow ditches, utility lines, drainage improvements, limits
of plowed fields, etc.
(4)
All existing prescriptive right-of-way dedications
within the Subdivision must be converted from prescriptive to a platted
right-of-way on the Final Plat.
4.
Private street.
(i)
A Subdivider may receive approval of one (1) or more private
streets if the following conditions are met:
(1)
The street is not shown on the City's Thoroughfare
Plan and is not or will not serve as the primary route between two
(2) or more Subdivisions or developments and an existing or future
public street;
(2)
The proposed street is built to City Standards
or with modifications approved by the City Engineer;
(3)
The private street is dedicated on a Final Plat
as a single and separate lot labelled as "Private Street" and deed
is granted to a Property Owners' Association for ownership and maintenance.
(ii)
The Planning and Zoning Commission may deny a
Final Plat on the basis of requested private streets or approve the
Final Plat with the condition that streets be dedicated to the City.
(Ordinance 475 adopted 6/28/22)
A.
Purpose. It is the intent of this section to:
1.
Prohibit the indiscriminate location and spacing of driveways
while maintaining reasonable vehicular access to and from the public
street system;
2.
Reduce conflicting turning movements and congestion and thereby
reduce vehicular accidents; and
3.
Maintain and enhance a positive image for the attraction of
new, high-quality developments in the City.
B.
Applicability.
1.
It shall be a violation of this UDC to construct, reconstruct,
relocate or in any way alter the design or operation of any driveway
without first being released by the City to begin construction.
2.
The City Engineer may prohibit a permit for a driveway if the
driveway is detrimental to the public health, safety and welfare.
C.
Common access.
1.
A Common Access Easement is required between abutting lots used,
zoned, or planned for nonresidential uses, mixed-uses, or multi-family
uses in any combination and fronting on any street section, unless
the City Engineer authorizes an exemption due to site constraints.
2.
Access easement.
(i)
The use of common driveways requires the dedication of a Common
Access Easement (also known as a mutual access easement or reciprocal
access easement) that affords access to a public street for each property
that is restricted from obtaining direct access due to the standards
of this subsection 2.5.10 (see Figure 2.5.10-1: Shared Driveway With
Cross Access Easement).
|
Figure 2.5.10-1: Shared Driveway With Cross Access Easement
|
|
(ii)
Common Access Easement dedications are dedicated
on the Final Plat of the subject properties, unless previously filed
by separate instrument with the County. Alternatively, the Common
Access Easement may be dedicated by separate instrument, so long as
the separate instrument requires City approval to amend.
(iii)
A Final Plat that includes a Common Access Easement
must state that the owner(s) of the property are responsible for maintaining
the Common Access Easement.
(iv)
A Common Access Easement shall encompass the entire
width of the planned driveway or 25 feet, whichever is greater, plus
an additional width of five (5) feet on both sides of the drive.
D.
Driveway design for non-State maintained roadways. The City may establish
standards to regulate the design and construction of driveways within
the Transportation Criteria Manual, including but not limited to driveway
dimensions and spacing (non-State maintained roadways) and deceleration
lanes for driveways on arterial streets required (non-State maintained
roadways).
E.
Driveway stacking.
1.
Driveway stacking is driven by the number of anticipated trips
based on parking spaces, and shall be provided on multi-family or
nonresidential properties for corresponding driveways in accordance
with Table 2.5-2: Minimum Driveway Stacking Requirements for driveways
that provide ingress/egress to parking areas of twenty (20) or greater
spaces. Stacking depth shall be measured from the right-of-way line.
2.
Stacking depth may be no less than 15' or the depth of the required
landscape buffer, whichever is greater.

|
1
|
The average number of parking spaces per driveway is calculated
by dividing the total number of parking spaces by the number of commercial
and multifamily driveways. (Service driveways are not included in
the calculation.)
|
|
2
|
The total number of parking spaces is the sum 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 five-foot
(5') wide, raised curb island or median. Planting requirements for
the island or median shall be one (1) Small Tree and one (1) five-gallon
(5 Gal.) shrub for every fifteen (15) linear feet. 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.
|
F.
Adequate sight distance.
1.
Driveways are prohibited where adequate sight distance is not
available for the established speed limit.
2.
If a field inspection indicates that driveway sight distance
may be insufficient, the applicant is 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. The determination of sufficiency
is at the sole discretion of the City Engineer.
G.
Sight visibility. Sight visibility easements shall be provided at
all intersections with a public street (see Section 6.4).
(Ordinance 475 adopted 6/28/22)
A.
Purpose. All development is recognized to add trips to the city's
transportation network. The purpose of this section is to outline,
based on the number of trips generated by the associated development,
the process an applicant will follow to determine the development's
impacts on the safety and functionality of the network, and to determine
the extent of the network modifications necessary to maintain the
city's adopted level of service.
B.
The following are the steps to be undertaken by the applicant to
determine the need for a TIA and roughly proportionate determination
study.
1.
When an application is submitted for development or, at the
discretion of the Building Official, for a building permit, the applicant
shall complete a Peak Hour Trip Generation Form reporting the number
of peak hour trips (PHT) generated by the proposed development as
determined from the most recent version of the ITE Trip Generation
Manual. PHT analyzed may be the A.M., Midday, P.M., Saturday, and/or
Sunday peak hours, based on the peak hour trip generation for that
given day and land use. Linear trip generation rates shall be used,
except where the ITE Trip Generation Manual clearly indicates the
use of regression equations better captures the trip generation estimates.
2.
The City will review and, if adequate, approve the Trip Generation
Report. Based on the findings of the Trip Generation Report:
(i)
If the proposed development will generate 49 PHT or fewer:
(1)
The applicant shall submit a turn lane analysis
as described in Section 2.5.12.F.
(2)
The applicant may be required to submit a circulation
study, in accordance with the TCM, at the discretion of the City Engineer.
(3)
A TIA is not required.
(4)
When a proposed thoroughfare is depicted on the
property subject to the application, the applicant is required to
either make the right-of-way dedication or prepare a Proportional
Mitigation Determination Report, as described in Section 2.5.12.E,
to determine their proportionate share of right-of-way dedication.
If there is no proposed roadway depicted on the Thoroughfare Plan,
this Report is not required.
(ii)
If the proposed development will generate more
than 49 PHT:
(1)
The applicant shall submit a turn lane analysis
as described in Section 2.5.12.F.
(2)
The applicant may be required to submit a circulation
study, in accordance with the TCM, at the discretion of the City Engineer.
(3)
The applicant shall submit a Proportional Mitigation
Determination Report as described in Section 2.5.12.E.
(4)
The applicant shall submit a TIA.
(iii)
If any of the following modifications to an existing
development are proposed, either the existing TIA will be required
to be updated or, if there is no prior TIA, a TIA will be required
and the applicant may be required to submit a circulation study, in
accordance with the TCM, at the discretion of the City Engineer.
(1)
The modifications result in an increase of 49 PHT
or more;
(2)
Land uses are changed resulting in different distribution
patterns;
(3)
Increases in land use intensities result in at
least ten (10) percent or greater PHT than those assumed in the previously
completed TIA.
(4)
Land uses are relocated or reallocated;
(5)
Site access points are increased, reduced, or relocated;
or
(6)
Traffic controls at access points are changed;
(iv)
For the modification of an existing Public School
campus and/or building within it, irrespective of the PHT generation:
(1)
The applicant shall submit a turn lane analysis
as described in Section 2.5.12.E [2.5.12.F].
(2)
The applicant shall submit a circulation study
in accordance with the TCM.
(3)
The applicant is not required to submit a Proportional
Mitigation Determination Report as described in Section 2.5.12.E.
(4)
The applicant is not required to submit a TIA.
(v)
If a previously completed TIA for a subject property was completed
more than three (3) years prior to the submittal date of the current
application, a new TIA will be required.
3.
If pursuant to Step 2.5.11.B.2, a Traffic Impact Analysis is
required, then the applicant shall undertake the following steps:
(i)
Conduct a meeting with city staff to determine the scope of
the Traffic Impact Analysis pursuant to Section 2.5.12.B.
(ii)
Complete the Traffic Impact Analysis in accordance
with City of Bee Cave UDC and TCM;
(iii)
Identify mitigation improvements and thoroughfare
plan implementation requirements if any, that are needed to support
the development; and
(iv)
Identify the total approximate cost, including
design, engineering and construction, to deliver the mitigation improvements
identified in Section 2.5.11.B.2(iii), if any.
(v)
The applicant, using the approved methodology of the City of
Bee Cave, shall determine the probable maximum amount of mitigation
improvements (measured in dollars) that may be attributable to the
development.
(vi)
The applicant shall compare the cost of the mitigation
improvements determined in Section 2.5.11.B.3(iv) to the maximum amount
of mitigation improvements identified in Section 2.5.11.B.3(v).
(1)
If the cost of the improvements identified in Section
2.5.11.B.3(iv) is less than or roughly equal to the maximum amount
of mitigation improvements identified in Section 2.5.11.B.3(v), then
the mitigation improvements identified in the TIA are said to be roughly
proportionate to the impact of the development.
(2)
If the cost of the improvements identified in Section
2.5.11.B.3(iv) is greater than the maximum amount of mitigation improvements
identified in subsection B.3(v), then the mitigation improvements
identified in the TIA must be limited by the city to an amount roughly
equal to the costs identified in Section 2.5.11.B.3(v).
(Ordinance 475 adopted 6/28/22)
A.
Purpose.
1.
A TIA is intended to adequately assess the potential traffic-related
impacts of a development on the existing and planned transportation
network, including but not limited to the thoroughfare system. The
purpose of these regulations is to:
(i)
Provide the safest and most efficient transportation system
in conjunction with the development review process;
(ii)
Inform the Applicant of the City's requirements
and expectations;
(iii)
Provide standard guidelines for the preparation
and review of a TIA; and
(iv)
Establish equitable and cost-effective mitigation
measures for the accommodation of identified impacts.
B.
Pre-submission meeting.
1.
Along with the submission of the development application triggering
the requirement for a TIA, but prior to the commencement of a TIA,
a TIA Scoping Meeting with the City Staff is required to jointly review
the requirements and methodology to complete the TIA and to establish
specific elements of the TIA. For all developments where a TIA is
required, a TIA scoping meeting shall be required. The TIA scoping
meeting shall include the engineer performing the TIA, the property
owner, or owner's agent, and city staff, and may include TxDOT and
county staff, if applicable.
2.
The purpose of the scoping meeting shall be to establish the
TIA requirements in accordance with generally accepted practice (as
described in the most recent version of the ITE Recommended Practice
Transportation Impact Analyses for Site Development). During the scoping
meeting, the following elements will be determined:
(i)
Study Area.
(ii)
ITE Land Use Code.
(iii)
TIA Analysis Periods.
(iv)
Trip Generation Rates and Calculation of Trips.
(v)
Trip Distribution & Assignment.
(vi)
Mode Split.
(vii)
Pass-by & Internal Trip Credits.
(viii)
Access locations & restrictions.
(ix)
Study Intersections & Adjacent Driveways.
(x)
Phasing of Development.
(xi)
Analysis Years.
(xii)
Other Developments to Include.
(xiii)
Planned Roadway Improvements to Include.
(xiv)
Growth Rate to be Applied.
C.
Responsibility of TIA preparation and review.
1.
Preparation.
(i)
A TIA must be prepared in accordance with all the guidelines
of this ordinance and submitted in accordance with the City's development
review schedule.
(ii)
The responsibility for TIA preparation rests with
the Applicant.
(iii)
A licensed Professional Engineer (P.E.) in the
State of Texas with PTOE certification and experience in traffic and
transportation engineering must conduct the study.
(iv)
The final TIA report must be signed and sealed
by the P.E. responsible for the analysis to be considered for review
by the City.
(v)
Application and review fees as indicated in the Fee Schedule
are due at the time of each submittal.
(vi)
City Staff will serve primarily in a review and
advisory capacity, and will only provide data to the Applicant when
available and at no additional cost to the City.
2.
Submittal.
(i)
It is the Applicant's responsibility to submit TIA reports,
final reports, including background data in native format, an electronic
copy of software analysis and executive summaries with the development
application.
(ii)
The proper number of reports, the timing for submission,
and the review of these reports shall be based on standard City development
review procedures.
(iii)
When a TIA is required for consideration of the
development application, an incomplete TIA or failure to submit a
TIA with the Application will cause the Application to be incomplete
and delay consideration of the requests (see Application Submittal
Procedures).
(iv)
Should it be determined that a TIA is required,
consideration of a related Application shall be deferred until the
applicant submits a completed TIA, the City has reviewed the TIA,
and the City has approved the TIA.
D.
TIA standards. To achieve uniformity in the evaluation process, the
following standards will apply:
1.
Determination of study area intersections & roadway segments:
Study intersections will be determined by the distribution of PHT
through the adjacent roadway network based on the trip distribution
identified in the TIA scoping meeting. The PHT will be distributed
to subsequent intersections until the minimum fifty (50) PHT or the
1.5 mile maximum distance is reached.
The signalized intersections, controlled approaches of unsignalized
intersections, and associated roadway segments within the study area
shall be identified during the TIA scoping meeting. Unsignalized intersections
include two-way stop controlled (TWSC) and all-way stop-controlled
(AWSC) intersections identified within the study area.
2.
Trip generation resources.
(i)
The City's standard for trip generation rates for various land
use categories are those published by the Institute of Transportation
Engineers (ITE) in the latest edition of Trip Generation Manual or
other published or recognized sources applicable to the region. The
City Engineer may accept alternate trip generation rates on a case-by-case
basis if the Subdivider can provide current supporting data substantiating
that their development significantly differs from the ITE rates. The
City Engineer must approve alternative trip generation rates in writing
in advance of the TIA submission. The City Engineer will approve the
ITE Land Use Code, use of data from Land Use Peak Hour vs Adjacent
Street Peak Hour and use of linear rates vs. regression equations.
(ii)
Trip reductions for pass-by trips, internal trips,
and mode splits are permitted, subject to analytical support provided
by the Subdivider and approval by the City Engineer, on a case-by-case
basis. Methodologies for calculation and application of internal and
pass-by credits and the provided pass-by percentages by Land Use Code
should be obtained from the ITE Trip Generation Handbook. Assumptions
relative to vehicle occupancy, or percentage of daily traffic to occur
in the peak hour must be documented and will be considered subject
to analytical support provided by the Subdivider.
3.
Study horizon years. The TIA must evaluate the impact of the
proposed Subdivision on future traffic conditions by establishing
existing traffic conditions, predicting future conditions without
the proposed project and comparing with the future traffic conditions
for the horizon year(s).
4.
Level of service. The appropriate Level of Service (LOS) (using
Highway Capacity Manual (HCM) delay values in seconds per vehicle)
shall be determined for each analysis period and each analysis scenario.
The following scenarios shall be included at a minimum: Existing Condition,
"No Build" Condition (existing traffic plus anticipated growth of
existing traffic plus neighboring development activity and road improvements
to be completed), and "Build" Condition ("No Build" plus project traffic).
An impact is identified as follows when comparing No Build results
with Build results for any analyzed peak hour using the LOS and Measures
of Effectiveness (MOE) per the HCM methodology for intersection capacity
analysis:
(i)
Signalized intersections:
(1)
If the No Build intersection LOS is C or better
and the Build intersection LOS drops below C.
(2)
If the No Build intersection LOS is C or below
and the Build intersection LOS drops to D, E or F.
(3)
If the No Build intersection LOS is F and the Build
intersection LOS is F and the delay increases by 10% or more.
(4)
If the No Build intersection LOS is D, E or F and
the Build intersection LOS does not decrease, but the overall intersection
delay increases by 10% or more.
(5)
If a No Build lane group movement or turning movement
LOS drops from C or better to a LOS E or F.
(6)
If a No Build lane group movement or turning movement
LOS is F and the corresponding Build LOS is F and the delay increases
by 10% or more.
(ii)
Unsignalized intersections:
(1)
AWSC Intersections:
(a)
If the No Build intersection LOS is C or better
and the Build intersection LOS drops below C.
(b)
If the No Build intersection LOS is C or below
and the Build intersection LOS drops to D, E or F.
(c)
If the No Build intersection LOS is F and the Build
intersection LOS is F and the overall intersection delay increases
by 10% or more.
(d)
If the No Build intersection LOS is D, E or F and
the Build intersection LOS does not decrease, but the overall intersection
delay increases by 10% or more.
(e)
If a No Build lane group movement or turning movement
LOS drops from C or better to a LOS E or F.
(f)
If a No Build lane group movement or turning movement
LOS is F and the corresponding Build LOS is F and the delay increases
by 20% or more.
(2)
TWSC intersections:
(a)
If the No Build LOS for a stop-controlled approach
or major road left-turn movement is C or better and the Build LOS
drops below C.
(b)
If the No Build LOS for a stop-controlled approach
or major road left-turn movement is C or below and the Build intersection
LOS drops to D, E or F.
(c)
If the No Build LOS for a stop-controlled approach
or major road left-turn movement is F and the Build intersection LOS
is F and the delay increases by 20% or more.
(d)
If a No Build LOS for a lane group movement or
turning movement at a stop-controlled approach or for a major road
left turn movement drops from C or better to a LOS E or F.
(e)
If a No Build LOS for a lane group movement or
turning movement at a stop-controlled approach or for a major road
left turn movement is F and the corresponding Build LOS is F and the
delay increases by 20% or more.
5.
Mitigation of impacts.
(i)
Mitigation of impacts are required if the proposed Development
would cause an impact as defined in subsection D.4 above. If mitigation
is required, the Applicant is responsible to mitigate the impact of
the proposed development, and would not be responsible for alleviating
deficiencies in the thoroughfare system that may occur without the
proposed development.
(ii)
Mitigation improvements for each intersection
shall be identified, for each time period of analysis (with a preliminary
cost estimate to implement the improvements), and roadway segments.
(iii)
Mitigation improvements may consist of off-site
improvements, the participation in funding for needed thoroughfares,
and intersection improvement projects;
(iv)
Examples of acceptable mitigation measures might
include:
(1)
Addition of traffic signals or AWSC or roundabout.
(2)
Addition of backage/quadrant roadway for cross
access.
(3)
Construction of medians, hooded left-turns, and
other access management measures.
(4)
Innovative intersections such as, RCUT'S, DDI'S,
DLT'S, SPUI'S.
(5)
Implementation of turn prohibitions.
(6)
Optimization of Signal Timing.
(v)
If a TIA identifies new traffic signals as mitigation measures,
the Signal Warrant Analysis for each new signal must be included in
the TIA.
E.
Mitigation improvements and roughly proportionate determination.
1.
The purpose of the TIA is to identify if any mitigation improvements
are necessitated by and attributable to the proposed development.
Mitigation improvements required by the city may include the following:
(i)
Implementation of the major thoroughfare plan; including right-of-way
dedication (right-of-way dedication value shall be determined using
the most recent appraisal district land values) and/or construction.
(ii)
Improvements inside the TxDOT right-of-way required
by the city and/or county, including right-of-way dedication, as approved
by TxDOT.
2.
For all phased development projects, implementation of the mitigation
improvements must be completed no later than the completion of the
project phase for which the TIA shows that they are required. Development
Applications for project phases subsequent to a phase for which a
mitigation improvement is required may be approved only if the mitigation
improvements are completed or the funds have been placed in escrow
for the improvements.
3.
Following the identification of mitigation improvements and
any other improvements necessitated by and attributable to the development,
the applicant shall utilize the methodology developed and approved
by the city to determine if the mitigation improvements identified
are roughly proportionate to the impact of the proposed development.
(i)
At the conclusion of the TIA, the applicant will summarize all
of the mitigation improvements identified in the TIA and the approximate
total cost of all mitigation improvements including design, engineering
and construction. Mitigation improvements that only serve the proposed
development (such as site plan related recommendations, turn lanes
at site access locations and traffic signals that are needed to serve
the proposed development) and provide minimal to no benefits to the
study area roadway network shall not be included in the cost of the
mitigation improvements (when compared to the maximum amount of improvements
attributable to the proposed development).
(ii)
The applicant will utilize the approved methodology
made available by the city to determine the maximum amount of improvements
(measured in dollars) that may be attributable to the proposed development.
(iii)
The applicant shall then compare the cost of
the mitigation improvements to the maximum probable amount of improvements
that may be attributable to the development.
(1)
If the cost of the mitigation improvements is less
than or equal to the maximum amount of improvements that may be attributable
to the development, then the mitigation improvements identified in
the TIA are said to be roughly proportionate to the impact of the
development.
(2)
If the cost of the mitigation improvements is greater
than the maximum amount of improvements that may be attributable to
the development, then the mitigation improvements identified in the
TIA are limited to an amount roughly equal to the maximum amount of
improvements that may be attributable to the development.
(iv)
The methodology utilized by the city shall be
as follows. The maximum amount of improvements attributable to a development
is roughly proportional to the demand created by a development. This
value shall be determined (measured in dollars) by multiplying the
following values together:
(1)
Intensity of the development (using independent
variable identified in the ITE Trip Generation Manual, e.g. number
of dwelling units, number of one thousand (1,000) square feet of leasable
floor area, etc.);
(2)
Number of vehicles - the peak hour trip generation
rate for the applicable peak hour (from the most current version of
the ITE Trip Generation Manual);
(3)
Length of the trip - the anticipated trip length
to/from the development on the city's thoroughfare network (a minimum
value of 2.0 miles and a maximum value of 2.5 miles shall apply);
and
(4)
Cost per vehicle-mile - the average cost per vehicle-mile
for the City of Bee Cave to deliver a typical roadway capacity improvement
project based upon the latest Average Unit Price List. The Average
Unit Price List shall be reviewed by the City Engineer on a regular
basis to ensure the Average Unit Price List is consistent with current
construction costs.
(v)
Projects within a planned development district where mitigation
improvements have been previously constructed at the cost of the applicant
shall receive credit for these improvements. The credit for improvements
shall be determined using the cost of the improvements at the time
they were constructed. This value shall be included with the total
cost of the mitigation improvements required to serve the development.
The land uses previously constructed or planned for, shall also be
included in the calculation of the maximum probable amount of improvements
that may be attributable to the development.
F.
Turn lane requirements at site access locations. Turn lanes are considered
a safety requirement serving the traffic associated with the proposed
development. As such, they are not considered mitigation of impacts
and are not included in the roughly proportionate determination study
in Section 1.1.1 B(iii) and (iv) [2.5.12].
1.
The construction of turn lanes may be limited due to topographic
conditions or the need to obtain right-of-way from adjacent property
owners. The applicant must show that all reasonable efforts have been
made to implement turn lanes when required. This may include relocating
driveways or roadways to allow for the construction of turn lanes
and/or offers to purchase right-of-way from adjacent property owners.
3.
Right turn deceleration lanes shall be required:
(i)
At all driveways or streets with a daily entering right-turn
traffic volume of five hundred (500) vehicle trips or at all driveways
or streets with fifty (50) entering right-turn vehicle peak hour trips;
and
(ii)
At street and driveway intersections in TxDOT
right-of-way with 50 peak hour right-turn vehicles; and
(iii)
Where unsafe conditions such as limited sight
distance, high travel speed, uneven grade, etc. may exist.
4.
Left-turn lanes shall be required:
(i)
At all median openings;
(ii)
If no median - at all driveways or streets with
an average daily entering left-turn traffic volume of five hundred
(500) vehicle trips or at all driveways or streets with fifty (50)
entering left-turn vehicle peak hour trips, or on all Collectors and
Arterials if no median;
(iii)
At street and driveway intersections in TxDOT
right-of-way; or
(iv)
Where unsafe conditions such as limited sight
distance, high speed, uneven grade, etc. may exist.
G.
Administration.
1.
The City Engineer, following review, shall take one or more
of the following actions on the TIA:
(i)
Approve the TIA and direct any necessary mitigation approaches
be included in associated agreements, such as Improvement Agreements,
if the project has been determined to have no significant impact or
where the impacts can be adequately mitigated;
(ii)
Deny the TIA request, where the impacts cannot
be adequately mitigated.
(iii)
Recommend that the density or land use mix of
the development be reduced such that it removes impacts that cannot
be mitigated.
2.
The City Staff, Planning and Zoning Commission, or the City
Council, as appropriate based on the type of Development (see Section
3.4 [3.5] for Zoning requests and Sections 2.1 and 2.2 for Plat requests),
may use the TIA as a basis for consideration of associated Development

Definitions.
The maximum number of vehicles that can pass a given point
under prevailing roadway and traffic conditions. Capacity represents
the ability of a roadway or an intersection to accommodate the vehicular
demand.
A summary of the crash history at nearby intersections and
on adjacent roadways during a specified time period. Crash trends
and contributing factors are identified, where present. Where site
traffic is anticipated to contribute to or exacerbate an identified
crash trend or safety issue, measures to mitigate or reduce the propensity
for crashes should be included in the TIA.
A qualitative measure of traffic operating conditions based
on equations utilizing quantitative values. Level of service (LOS)
describes the quality of traffic operating conditions and is rated
from "A" to "F". LOS A represents the most desirable condition with
the free-flow movement of traffic with minimal delays. LOS F generally
indicates severely congested conditions with excessive delays to motorists.
Intermediate grades of B, C, D, and E reflect incremental increases
in the average delay per stopped vehicle. Delay is measured in seconds
per vehicle.
Level of Service analyses conducted as part of a TIA shall
be determined using procedures of the latest edition of the Highway
Capacity Manual, Special Report 209 published by the Transportation
Research Board (TRB).
The percentage of trips by mode. For example, bicycle, walking,
single-occupant automobile, shared ride or transit.
An analysis of vehicle stacking/queueing and identification
of the needed lane storage necessary to accommodate anticipated maximum
vehicle queues. Typically performed for drive-through facilities,
drop-off zones to schools and day care facilities.
An evaluation of the available horizontal and vertical sight
distance for entering and exiting traffic movements at access points
to a site, intersection, or roadway section.
The time period, in seconds, required for one complete sequence
of traffic signal indications.
A part of the signal cycle allocated to a traffic movement
or any combination of traffic movements.
A study that provides information to:
Identify impacts to the road network, created by the traffic
generated by a proposed development; and
Determine whether the existing and planned thoroughfare system
can accommodate the traffic to be generated by a proposed development;
and
Identify and evaluate the appropriate improvements and recommendations
needed to mitigate the impacts from the development.
The designated time periods to be studied and analyzed for
assessment of traffic operations as part of a TIA submittal.
Signs, signals, pavement markings, or device placed or erected
for the purpose of regulating, warning, guiding, or restricting vehicular
traffic or pedestrians.
The use of a computer model to provide detailed analysis
of the interaction between traffic, roadway geometry, and traffic
control devices.
The distribution of estimated peak hour trips generated by
the proposed development onto the street system using existing traffic
patterns, demographic data, and travel characteristics of land uses.
The estimated number of trips, entering and exiting, generated
by proposed land uses and based on variables that may include building
size, type of dwelling unit, employees, land area, etc. Trip generation
calculations are typically based on statistical data in the ITE Trip
Generation publication or through collection of trip data at similar
land uses.
A determination of the need for turn lanes and an analysis
of storage requirements combined with acceleration/deceleration length
requirements for driveways, median openings and intersections based
on existing and future roadway volumes, geometry, speeds and traffic
controls. The City of Bee Cave utilizes the TxDOT Roadway Design Manual
and Access Management Manual for turn lane standards.
The ratio of daily or peak hour traffic volume to the capacity
of a roadway, lane or intersection. A V/C at or over 1, represents
an over-saturated condition where the capacity of the roadway, lane
or intersection exceeds the demand and fails to operate effectively.
