EXHIBIT "B"
That Chapter 12, "Unified Development Ordinance," Article 7 "General Development
Standards" Section 12-7.13 "Traffic Impact Analysis" of the Code of Ordinances of the City of
College Station, Texas, is amended to read as follows:
"Sec. 12-7.13. Traffic Impact Analysis.
This section establishes requirements and procedures pertaining to traffic impact analysis ("TIAs"). This Article is
intended to inform the applicant of the City's expectations to ensure safe and adequate access to development
properties; adequate traffic flow on existing and proposed/planned roadways; and sufficient connectivity of the
existing and proposed/planned roadway system attributable to their proposal. In addition this Article is intended to
expedite the City's review of TIA reports, provide standard criteria for evaluating proposals, and identify some
potential mitigation measures.
The TIA is intended to form the basis for design of any proposed access/roadway system to ensure coordination of the
proposed land use with the transportation needs resulting there from. The City of College Station and the developer
share responsibility to identify and solve transportation issues arising from land development.
College Station requires that TIAs accompany certain zoning applications, certain site plan applications, and certain
preliminary plan applications. It is intended that any TIA required for any type of land development proposal will
complement the overall goal of ensuring that adequate transportation facilities are in place to serve land uses by the
time those uses are occupied and generating traffic. These purposes are further amplified below.
A. Purpose.
1. Zoning TIA.
The goal of a TIA submitted in conjunction with a zoning request is to determine the effect that uses
allowed within various proposed zones will have on existing and/or any proposed/planned roadway
systems, and to ensure there is a balance between future land uses and future transportation systems.
Zoning applications that are required to have a TIA are evaluated using both current and long-term
traffic and roadway scenarios.
The TIA will determine whether acceptable levels of service will be maintained for traffic flow within
the proposed project and in its study area. Where service levels fall below acceptable standards,
mitigation solutions will be analyzed for their effectiveness. A TIA for a zoning request should not
recommend mitigation measures that are inconsistent with any traffic or roadway provisions of the
Unified Development Ordinance or the City's Comprehensive Plan,including the Thoroughfare Plan.
The Planning and Zoning Commission and the City Council shall consider the findings of the TIA in
approving or disapproving zoning changes to the extent allowed by law.
2. Preliminary Plan TIA.
The goal of a TIA submitted in conjunction with a preliminary plan is twofold:to assess the adequacy
and safety of proposed access to adjacent existing or planned roadways(or designs proposed for such
access or roadways); and to determine effects the proposed project may have on current and future
land development and roadway systems in its study area. Generally, the TIA uses current and
anticipated near-term traffic volumes and roadway configurations for the analysis.The process should
ensure that the roadway system is,or will be,adequate to accommodate the proposed use and that safe
and adequate access will be provided for travel between the site and the public roadway system.
Where the TIA shows levels of service falling below acceptable minimums on roadway systems in its
study area the TIA will recommend appropriate mitigation measures and demonstrate their
effectiveness. Example mitigation techniques may include adding/lengthening deceleration/turn
lanes, improving driveway access, providing connectivity, and modifying traffic control devices.
fb7edb53-000d-406f-9b1d-8b6f7942f4ab
Ordinance No. 2016-3796 Page 6 of 16
Combinations of these techniques and other techniques can be considered. A TIA for a preliminary
plan should not recommend mitigation measures that are inconsistent with any traffic or roadway
provisions of the Unified Development Ordinance or the City's Comprehensive Plan, including the
Thoroughfare Plan. The Planning and Zoning Commission shall consider the findings of the TIA in
approving or disapproving preliminary plans to the extent allowed by law.
3. Site Plan TIA.
The goal of a TIA submitted in conjunction with a site plan is twofold: to assess the adequacy and
safety of proposed access to adjacent existing or planned roadways (or designs proposed for such
access or roadways); and to determine effects the site project may have on current and future land
development and roadway systems in its study area. Generally,the TIA uses current and anticipated
near-term traffic volumes and roadway configurations for the analysis.The process should ensure that
the roadway system is, or will be, adequate to accommodate the proposed use and that safe and
adequate access will be provided for travel between the site and the public roadway system.
Where the TIA shows levels of service falling below acceptable minimums on roadway systems in its
study area the TIA will recommend appropriate mitigation measures and demonstrate their
effectiveness. Example mitigation techniques may include adding/lengthening deceleration/turn
lanes, improving driveway access, providing connectivity, and modifying traffic control devices.
Combinations of these techniques and other techniques can be considered.A TIA for a site plan should
not recommend mitigation measures that are inconsistent with any traffic or roadway provisions of
the Unified Development Ordinance or the City's Comprehensive Plan, including the Thoroughfare
Plan. The Planning and Zoning Commission shall consider the findings of the TIA in approving or
disapproving site plans to the extent allowed by law.
B. Definitions.
1. Trip Generation Rates.
Trip Generation Rates are used to estimate the amount of vehicular traffic generated by proposed
rezoning or a proposed site plan. For Zoning and Preliminary Plan TIAs, these rates are shown by
zoning district in the table below. Preliminary Plan trip generation rates should be based on the
underlying zoning district. Site plan TIAs shall use rates set forth in the latest edition of the Trip
Generation Report published by the Institute of Transportation Engineers (ITE), unless said Report
does not adequately address the type or intensity of the proposed land use. In this event the applicant
or his agent shall submit projected vehicle trips to the Administrator. For land uses adequately
represented in said Report, alternate trip generation rates shall not be accepted.

2. Design Year.
The design year is the point in time upon which assumptions pertaining to land use, population,
employment, and transportation facilities are based. All TIAs shall use a design year based on the
expected date of project occupancy, and shall include consideration of nearby development that has
been approved and will contribute traffic volume to the proposed project's study area.
3. Peak Periods.
Peak periods relate to times of day experiencing the greatest hourly traffic flow rates.Two(2)"peaks"
are to be addressed by a TIA: The morning and afternoon peak hours (or projected peak hours) of
existing (or planned) roadways serving the proposed land development. Typically roadway peak
periods are between 7:00 and 9:00 a.m. and between 4:00 and 6:00 p.m.
4. Base Volumes.
Base volumes shall be based on current traffic counts adjusted to the expected date of project
occupancy plus volumes generated by nearby future development(all phases)that has been approved
by the City.When available,base data will be supplied by the City Traffic Engineer.In all cases where
traffic counts are needed and are not available,the developer or his agent shall be required to collect
such data according to guidelines approved by the Administrator.
5. Level of Service(LOS).
Level of Service is a measure of the extent of congestion experienced on roadways. It is measured
through analysis of traffic operating conditions on roadway links and at intersections,using techniques
presented in the latest edition of the Transportation Research Board's Highway Capacity Manual.

Ordinance No. 2016-3796 Page 9 of 16
C. Applicability.
1. Zoning TIA.
Any zoning request, except for certain "redevelopment" areas as designated on the Comprehensive
Plan Future Land Use and Character Map, which is expected to generate at least one hundred fifty
(150) vehicle trips during any peak hour period requires a TIA. Where the Comprehensive Plan
designates a property as "Redevelopment" a TIA is required if the zoning request is expected to
generate at least one hundred fifty (150) vehicle trips during any peak hour period more than those
generated by the currently approved use(s) on the property. A zoning request involving multiple
zoning districts is required to have a TIA based on the total traffic generated for all the proposed
districts.A TIA may be required for a zoning request that generates less than one hundred fifty(150)
trips in the peak hour, where the peaking characteristics could have a detrimental impact on the
transportation system as determined by the Administrator.
A TIA shall be required unless the applicant demonstrates to the satisfaction of the Administrator that
a TIA is not necessary for the proposed rezoning request. In cases where a TIA is required, the
rezoning application will be considered incomplete until the TIA is submitted
2. Preliminary Plan TIA.
Any proposed development requiring preliminary plan approval,which is expected to generate at least
one hundred fifty (150) trips in any peak hour period requires a TIA. A TIA may be required for
preliminary plans that generate less than one hundred fifty(150)trips in any peak hour period where
the peaking characteristics could have a detrimental impact on the area's vehicular transportation
system as determined by the Administrator.
A TIA shall be required unless the applicant demonstrates to the satisfaction of the Administrator that
a TIA is not necessary for the proposed project.In cases where a TIA is required,the preliminary plan
application must be accompanied by the TIA
3. Site Plan TIA.
Any proposed development requiring site plan approval, excluding developments located in the
zoning classifications of NG-1, NG-2, or NG-3, which is expected to generate at least one hundred
fifty (150)trips in any peak hour period requires a TIA. A TIA may be required for site plans that
generate less than one hundred fifty (150) trips in any peak hour period where the peaking
characteristics could have a detrimental impact on the area's vehicular transportation system as
determined by the Administrator.
A TIA shall be required unless the applicant demonstrates to the satisfaction of the Administrator that
a TIA is not necessary for the proposed site project. In cases where a TIA is required, the site plan
application must be accompanied by the TIA.
D. Methodology.
1. Professional Engineer to perform TIA.
All required TIAs shall be performed by a professional engineer licensed in the State of Texas
qualified to perform such analysis. Qualifications may include,but are not limited to, certification as
a Professional Traffic Operations Engineer or Professional Transportation Planner by the Institute of
Transportation Engineers or certification by the Texas Department of Transportation to conduct traffic
engineering studies.
2. Pre-Submittal Meeting.
A pre-submission consultation with the Administrator is required at the time of the Pre-Application
Conference to discuss whether a TIA is required and, if so, the relevant aspects thereof. The study
area will be defined to include nearby land developments (existing or approved), the street network
to be examined(the "study network"), and the minimum extent of analysis.In addition,details of the
procedures, assumptions, data collection, and analysis methodology(ies) will be determined at this
fb7edb53-000d-406f-9b1d-8b6f7942f4ab
Ordinance No. 2016-3796 Page 10 of 16
meeting. Traffic from other nearby developments that have been approved but not yet constructed
will be accounted for in the TIA as determined by the Administrator. The Administrator may require
other specific assumptions such as the percent of trucks to match local conditions. The City may
require analysis of peak fifteen(15)minute intervals for certain types of land uses that generate major
traffic surges such as,but not limited to,stadiums,movie theaters, arenas, and schools.
3. Zoning TIA Content.
a. Study Area.
A map(s) will delineate the TIA study area, including land areas to be considered and all
existing/planned streets therein, and the "study network" (those streets and intersections
requiring specific analysis). The study area shall be determined based on the geographical area
most affected by the proposed zoning request as determined by the Administrator after
conferring with the applicant's traffic engineer.
b. Existing Zoning.
A description by zoning classification of the existing zoning in the area proposed for rezoning.
c. Proposed Zoning.
A description of the proposed zoning including land area by zoning classification.
d. Roadway Network.
A description of the existing and proposed/planned roadways of all classifications and traffic
volumes on the study network within the study area.
e. Impact Determination.
An assessment of projected traffic volumes is to be made for all study network roadways,
comparing those with allowable volume limits on roadways classed as collector and local, and
providing a description of the volume/capacity(V/C)ratio for all roadways in the study network.
In addition delay projections for signalized and unsignalized intersections in the study network
will be determined. Where V/C ratios and intersection delay are the measures of effectiveness
Level of Service D or better must be maintained. The analysis shall contain the following
minimum information:
1. Proposed Trip Generation.
Show in tabular form trip generation rates(see Table 1,2,or 3 as applicable)and the total
trips generated based on proposed zoning.
2. Existing Trip Generation.
Show in tabular form trip generation rates(see Table 1,2, or 3 as applicable)and the total
trips generated based on existing zoning.
3. Net Increased Trip Distribution and Assignment.
Show proposed trip generation minus existing trips and the calculation of new trips
generated. The net increase in trips generated by the zoning request is to be added to the
base volumes projected by design year. Twenty-four-hour and peak hour volumes must be
calculated. Distribution and assignment calculations must be provided.
4. Level of Service Analysis.
Show in tabular form peak hour Level of Service for existing and proposed zoning.
Calculations shall include all thoroughfare links and intersections. Calculate level of
service and percentage change (when compared to base volumes) for each link and
intersection.

Ordinance No. 2016-3796 Page 11 of 16
5 Neighborhood Traffic Analysis.
If a proposed rezoning is projected to increase the traffic on an existing or
proposed/planned minor collector or local residential roadway (street) at least ten (10)
percent, a neighborhood traffic analysis shall be performed. This analysis will include an
evaluation of existing and projected traffic on the affected roadways. Where the projected
traffic exceeds the limits indicated in the BCS Design Guidelines, street network layout
must be adjusted to lower this traffic volume.
6. Conclusions.
Summarize points of conflict and congestion, identify all thoroughfare links and
intersections not achieving Level of Service D or better, and the percentage change
resulting from the proposed zoning change. The results of examining collector and local
residential roadways,including the findings of any neighborhood traffic analysis must also
be summarized.
f. Mitigation.
A description of the mitigation measures proposed for achieving acceptable service thresholds
shall be shown. Analysis of the study network as adjusted by the proposed measures must be
documented. Traffic produced by the proposed zoning request plus traffic levels projected by
the time of project occupancy should result in Level of Service D or better. Locations not
meeting Level of Service D where the proposed zoning contributes five(5)percent or more of
the peak hour traffic must be mitigated by the applicant. Acceptable methods of mitigating
negative traffic impacts include any one(1), or a combination of,the measures listed below but
is not limited to those listed.
1) Modifying the zoning request so that resulting traffic volumes yield Level of Service D or
better throughout the study network.
2) Modify any street network proposed as part of the development project in terms of size,
layout,connectivity,intersection layouts,or location of termini with thoroughfares,or any
combination of such changes.
3) Limit development densities/intensities within one (1) or more zoning classifications or
land parcels to result in acceptable traffic volumes.
4) Making minor thoroughfare or intersection improvements, such as adding/extending or
relocating turn lanes,adding/extending acceleration and/or deceleration lanes,adding non-
traversable medians, relocating median openings, using special directional median
openings,or using special features to facilitate safe U-turn maneuvers.
Amendments to the City's Thoroughfare Plan shall not be accepted as a means of mitigating
negative impacts, unless the proposed amendment(s) can be shown to enhance capacity and
safety and will be constructed as part of the proposed land development project.
g. Planning and Zoning Commission Report.
The Planning and Zoning Commission shall make a report to the City Council on all TIAs it
considers in conjunction with requests for rezoning.The Planning and Zoning Commission may
make a recommendation for approval,modification, or denial of the zoning case based on other
planning factors in addition to its review of the TIA.
Where the identified impacts of the proposed zoning cannot be adequately mitigated, the
Planning and Zoning Commission may recommend to the City Council one (1) or more of the
following actions:
1. Denial of the zoning case in total or in part.

Submittals of TIAs for preliminary plan projects shall include the following:
a. Study Area.
A map(s) delineating the TIA study area, including land areas to be considered and all
existing/planned roadways therein, and the "study network" (those roadways and intersections
requiring specific analysis).The study area will be determined by identifying the geographical
area most affected by the proposed development as determined by the Administrator after
conferring with the applicant.In general the study area will cover all intersections through which
at least ten(10)percent of the proposed development's site traffic passes,and shall extend to and
include at least the first traffic signal in all directions if within one(1)mile of any portion of the

A depiction shown in tabular form,twenty-four-hour and peak hour volume/capacity ratios
for links and intersections within the study area. This analysis should be done for the
following traffic conditions: existing traffic, existing traffic plus projected traffic.
4. Neighborhood Traffic Analysis.
If the TIA calculations show that a proposed preliminary plan increases traffic on a minor
collector or local residential roadway (street)by at least ten(10)percent, a neighborhood
traffic analysis shall be performed. This analysis will include an evaluation of existing and

the development. It also must identify any safety and operational problems (e.g.,
driveways, sight distances,median openings, and signalization)within the study area.
g. Mitigation.
A description of the mitigation measures proposed for meeting acceptable traffic service
thresholds shall be shown. Where the development is contributing five (5) percent or more of
the traffic at locations failing to meet Level of Service D or better the total trips should be
mitigated by the applicant to low enough levels to achieve the required standard (or to pre-
development levels, if pre-development level is less than Level of Service D). Acceptable
measures for mitigating negative traffic impacts include any one(1), or a combination of,those
listed below.
1) Modifying the density or intensity of land use,such as a reduction in square footage or the
percentage of commercial use to result in traffic levels meeting Level of Service D or
better;
2) Phasing approval and construction of a project until additional roadway capacity becomes
available;
3) Modifying the proposed street network in terms of size, layout, connectivity, intersection
layouts, or location of termini with thoroughfares or any combination of such changes;
4) Making off-site improvements including the construction of additional lanes, increases in
storage lane capacities,or modification/installation of signalization,to list some examples.
h. Costs of Mitigation.
Mitigation improvements which are attributable to the proposed development shall be funded at
the developer's expense. Any other improvements shown which are consistent with the
Thoroughfare Plan may be repaid by the City in accordance with its cost sharing policies.
5. Site Plan TIA Content.
Submittals of TIAs for site plan projects shall include the following:
a. Study Area.
A map(s) delineating the TIA study area, including land areas to be considered and all
existing/planned roadways therein, and the "study network" (those roadways and intersections
requiring specific analysis).The study area will be determined by identifying the geographical
area most affected by the proposed development as determined by the Administrator after
conferring with the applicant.In general the study area will cover all intersections through which
fb7edb53-000d-406f-9bld-8b6f7942f4ab
Ordinance No. 2016-3796 Page 14 of 16
at least ten(10)percent of the proposed development's site traffic passes,and shall extend to and
include at least the first traffic signal in all directions if within one(1)mile of any portion of the
site. Existing roadway and intersection capacities shall be shown.
b. Existing Zoning and Development.
A description of existing zoning including land area (gross and net) by zoning classification,
square footage, density of hotel rooms, dwelling units, etc. Also, a description of development
currently within the proposed site plan, including showing how it will be affected by the new
development proposal;
c. Thoroughfare Network.
A description of existing thoroughfares, signals, signal phasing and traffic volumes within the
study area;
d. Proposed Development.
A description of the proposed development including land area(gross and net), square footage,
density of hotel rooms,dwelling units,etc.Also a description of anticipated roadway conditions
expected by the date of occupancy of the proposed development shall be included.
e. Proposed Access.
Identification of the proposed access driveways for the site. This shall include the location and
number of lanes, proposed traffic controls, and relationship to on-site circulation features for
each proposed point of access. It must also include any proposed modifications to adjacent
roadways. Once the TIA and an access plan has been approved,the final location and design of
all access points shall meet or exceed the current access management and roadway design
policies of the entity responsible for the condition of that portion of adjacent roadway.
f. Impact Determination.
A determination of the Level of Service for all roadways and intersections in the study area shall
be included, as shall an evaluation of pedestrian, bicycle, and motor vehicle safety conditions
along all the roadway frontage of the site. The analysis shall contain the following minimum
information:
1. Proposed Trip Generation.
A calculation of the total trip generation by use within the study area assuming full
development and occupancy, including both peak hour and twenty-four-hour information
show any reductions attributed to passers-by, mixed use, etc. show trip generation by use
in tabular form with land use trip generation rates and trips generated.
2. Trip Distribution and Assignment.
A calculation of trips generated by the proposed development as added to the base volumes
projected for the design year. Peak hour volumes must be calculated. Distribution
assumptions(and the bases therefore)and assignment calculations must be provided.
3. Level of Service Analysis.
A depiction shown in tabular form,twenty-four-hour and peak hour volume/capacity ratios
for links and intersections within the study area. This analysis should be done for the
following traffic conditions:existing traffic,existing traffic plus projected traffic.Capacity
analyzes must be shown for all points of ingress and egress,median breaks, and turn lanes
associated with the proposed site.
4. Neighborhood Traffic Analysis.

Ordinance No. 2016-3796 Page 15 of 16
If the TIA calculations show that a proposed site project increases traffic on a minor
collector or local residential roadway(street)by at least ten (10)percent, a neighborhood
traffic analysis shall be performed. This analysis will include an evaluation of existing and
projected traffic on the affected roadways. Where the projected traffic exceeds the limits
indicated in the BCS Design Guidelines mitigation to lower this traffic may be required.
5. Conclusions.
A summary of findings must be reported. It must show all adjacent roadways and
intersections noting those that fail to provide Level of Service D or better, and the percent
increase in total traffic produced by the proposed site project. In addition the report must
demonstrate that the proposed access design will provide safe and adequate access to the
project site.It also must identify any safety and operational problems(e.g.,driveways,sight
distances,median openings, and signalization)within the study.
g. Mitigation.
A description of the mitigation measures proposed for meeting acceptable traffic service
thresholds shall be shown. Where the development is contributing five (5) percent or more of
the traffic at locations failing to meet Level of Service D or better the total trips should be
mitigated by the applicant to low enough levels to achieve the required standard (or to pre-
development levels, if pre-development level is less than Level of Service D). Acceptable
measures for mitigating negative traffic impacts include any one(1), or a combination of,those
listed below.
1) Modifying the density or intensity of land use,such as a reduction in square footage or the
percentage of commercial use to result in traffic levels meeting Level of Service D or
better;
2) Phasing approval and construction of a project until additional roadway capacity becomes
available;
3) Improving the access plan by dealing with features such as overall site arrangement, the
placement and design features of access points, provision of additional access points to
roadways not immediately adjacent to the property, provision of alternate controls, or
adjustments in the site circulation system;
•
4) Making off-site improvements including the construction of additional lanes, increases in
storage lane capacities, or modification of signalization,to list some examples.
h. Costs of Mitigation.
Mitigation improvements which are attributable to the proposed development shall be funded at
the developer's expense. Any other improvements shown which are consistent with the
Thoroughfare Plan may be repaid by the City in accordance with its cost sharing policies.
E. Criteria for Approval.
The City shall consider the following standards in determining whether a proposed rezoning or submitted
site plan project meets an acceptable Level of Service:
1. Design Requirement.
The proposed rezoning or site plan project is consistent with the City's adopted access management
and design requirements and is consistent with the design requirements of the Texas Department of
Transportation on roadways maintained by such agency.
2. Level of Service D.
The desirable minimum Level of Service for the City of College Station is a Level of Service D as
that term is described in the Transportation Research Board's Highway Capacity Manual.
