Exhibit A
Amendment 1 to Contract 5436
Contract #5436
Amendment to Scope of Services
Road Impact Fee and Rough Proportionality Policy Development
The following Scope of Services is an amendment to the approved scope af services foi° the referenced
project. This amendment generally involves cevisions to further update the Mobility P(an to develop a
travel demand mode{, expand the functional classifications, develop alternative design cross sections foc
the type of roadway incorporaYing the pedestrian and bicycle components, evaluate future raadway
service and alignments to provide cecommendations to current plan, and any related meetings.
The various taslcs affected by this anzendment are listed below along with the associated chai°ges. The
total contract amendment expenditure shall not exceed one-hundred and sixty-five thousand do[lars
($165,000) and is detailed �n Attachment 1.
1 1 !' • C� . -
Task 1— Public Invo(vement and Meetings
A. Staff Technical Committee Meetings - Up to six (6) meetings wili be atte'lded with the OWNER
and are envisioned to cover the following elements; issues identification, travel demand modeling
(2 meetings}, expanded functional classification systetn to include type of roadway, development
of alternative cross sections, and overall plan development.
B. Public Meetings - Three (3) Public Meetings will be attended to garner public input. These are
envisioned ta accur at the outset of the project for issues identification and towards the end of the
project for Plan recomrnendations. These public meetings could include presentations to the
Mobility Committee and/or City Councrl.
Task 2 — Data Collection
T/ze following infornzation will be collected:
• OWNER contacts — The OWNER will provide the organizational structure for the project team
for the completian of the Mobility Roadway Plan update.
• Previous Mobility Roadway Plan Reports — Tlie OWNER will provide the CONSULTANT tlie
previous Mobility Roadway Plan report and any relevant Mobility Roadway Plan documentation
created since the adoption of the current Mobi(ity Roadway PIan.
• OWNER provided list of current raadways that have been identified for modificatian to the
Mobility Roadway P[an.
• Maps — The OWNER shall pcovide CONSULTANT with available GIS shapefiles, associated
databases, and layer fifes in ESRI ArcGIS10.x format. All data shall be projected in NAD $3
State Plane, South Central Texas Zone coordinates. Data should include:
i. Available ROW information;
ii. Existing uti[ity locations;
iii. Existing gas we(ls and gas li�ze;
iv. Cantours; and
v. FEMA flood plain data.
Travel Model — The CONSULTANT will worl< on obtaining the current NCTCOG model used
far its Mobility 2040 Plan. The CONSULTANT intends to use their current transportation mode[

(NCTCOG). The NCTCO model will be incorporated into the CONSULANTS model.
Task 3— Existing Conclitions Analysis
The CONSULTANT will condt�ct and general overview of the existing thoi•ougl�face system to serve as a
basis plan development. Elements included as part of this assessment will include; existing functional
classification, existing network level-of-service, identification of critical intersections, existing and future
major traffic generatois, current daily volumes and non-motorized and transit connectivity.
Traffic volumes will be based on available information as compiled by the OWNER and supplemented
with data fcom the current Raadway Impact Fee Study.
Task 4— Develop and Calibrate Existing ("Base Year") Model
The CONSULTANT will update the travel demand model identified fo�° use in Taslc 2. The
CONSULTANT will revise the TransCAD model to reflect the network configuratians and demographic
datasets cequiced to model the existing transportation system.
' � 1'• �r
The CONSULTANT will review and modify Yhe existing traffic survey zones from the travel
demand modeL The trafftc sutvey zones will be agreed upon prior to modeling work. Any
change to the traffic survey zones after modeling would result in additional services.
: 1� � , �• ��
The existing demographic datasets will be used from the current Roadway Lnpact Fee Study
project broken inta the agreed upon traffic survey zones.
1- • � , "�,i, � j7
The CONSULTANT will update the roadway network to reflect the existing roadway netwark.
! � � �;
The travel demand model will then be calibrated using the existing traffic counts coilected as part
of the cw•rent Roadway Itnpact Fee Study project. The CONSULTANT will calibrate the
network by functional class and up to 6 screen lines throughout the City according to the FHWA
modeling methodology. Once calibrated, this existing conditions model (or "base year" model)
will be used to develop a baseline condition.
1 . � �, I � 1 ,: � !' �
The CONSULTANT will utilize the Base Year Model deve(oped as part of Task 4 to assist in the
development of the futuce model. The CONSULTANT will develap a 2040 Build Out Model. The
purpose of the 2040 (Build Out) model is to develop the ultimate Mobility Roadway Plan.

The CONSULTANT wil( update the roadway networl< utilized in the future analysis. Up to four
different roadway networks ace intended to be analyzed for the 2040 (Build Out) model. An
example of these roadway networks are as follaws:
• Existing Roadway Network
• Base Future Netwoi°k (Existing + Committed Roadway Projects);
• Other Raadway Scenario; and
• Updated Mobi(ity Roadway Plan.
The actua( caadway networks will be agreed to prior to model analysis.

Based on work efforts iri Tasks 1-5, the CONSULTANT will conduct transportation planning to address
tlloi°oughfai°es.
Travel focecast modeling in Task 5 will identify system needs and seive as a basis for recommendation of
roadway sizing. Incorporated into this thought process will be considerations for road or lane diets, as
appropriate.
A. Functional Street Classifications: This task w►11 include research of national best �cactices
and industry standacds and make recommendatians for new functional street classifications to
be considered as part of the plan update.
B. Defz�e Type ofStreets: Recommendations will consider Context Sensitive Design for all
transportation modes and built upon concepts that are wlder consideration locally and
regionally. This concept bi°eaks down the functional sti•eet class►ficatiort into types of streets
which may be based on the surrounding land uses. Cross sections and plan views will be
developed.

revisioits to the Desigil Criteria Manual will be p►-oduced and a process wiil be created ta
implement the changes.
D. Alzgnment Consider^ations: CONSULTANT wilf analyze a[ignment alternatives at a
conce�tual fevel for the Mobility Roadway Plan. The CONSULTANT will use available
COII�OLII'S, parcel data/right-of-way information, utilities, flood plain and gas well locations to
aid in the cecommendation of alignment. The CONSULTANT will rely upon the accuracy of
th� data col[ected during Task 2. TIZis task anticipates looking at up to ten (10) roadway
alignments (new and existing). No roadway design or survey services wece assumed to be
included as part of this project.
E. Intersection Irz�provem.ents: CONSULTANT wil[ identify intersection impravement to aid in
the overall mobility of tlle City. These impravements may include but are not limited to
signals, turn lanes, roundabouts, etc.

Mobility Roadway Plan documentation will be sumtnarized in a concise report detailing;
study overview, plan gaals and abjectives, existing transportation conditions, travel demand
modeling, functional c[assification system, future needs and plan recommendations. The
Mobility Roadway P1an wi11 be suminarized on a single map and depicting roadway
functional class throughout the City. Supporting maps wi(l detail the composition of each
functional class facility (i.e. street type}.
A draft plan will be prepared and submitted ta the OWNER for review and comment. Based
on comments, a revised draft ("final draft") will be prepared and presented to the Planning
atla Z011ll1g C01111111SS1011 FOC CO11S1(�eP3�1011. SU�JOCt �0 CO1111111SS1011 CO1I1111�11iS, a final repai°t

(PDF farmat) of the draft plan will be submitted to the City far staff review. Ten (10) copies
of the draft final and final reports will be prepared and submitted to the city for distribution.
