3. PROJECT WORK PLAN
INTRODUCTION
The JHK Project Team has developed a work plan for this study that will
ensure the timely delivery of the project products. The outline of the proposed
study approach is contained in Exhibit 3-1. A detailed description of the elements
of the study approach is presented later in this section of the proposal. The study
approach consists of eight major tasks with various associated subtasks. A series of
workshops and public meetings has been included in the study approach. These
workshops and meetings will occur at strategic times during the project to support
other tasks. The timing of these workshops and meetings relative to the other task
requirements is given in the project work time schedule.
It should be noted that, in addition to the project deliverables that were
specifically requested in the RFP, JHK is proposing to supply two other elements
that will significantly enhance the final product. The first is a documentation of the
" possible funding sources and levels of funding available to construct and maintain
transportation facilities. This information will significantly aid the Town of Marana
~ decision making regarding project implementation priorities, and the levels of new
funding that may be required.
The second additional product is a video log of the key highway facilities in
the study area. The video log is relatively easy and inexpensive to produce, and it
provides valuable information on the condition of the existing highway facilities.
For example, during the project JHK will use the video log to validate the PAGTPD
existing network assumptions for such factors as the number of traffic lanes, and
posted speed limits. After completion of this project the video log can be used by
the Town of Marana to review signing and pavement markings, shoulder conditions,
roadway design and sight distance problems, and identify roadside hazards. JHK
used this video, technique quite successfully on a recent Pima County project where
over 200 miles of roadway were logged.
The JHK Project Team has identified several key factors which will be
important during this project. A discussion of these, and comments on how each
factor will be addressed, is given below.

The TRANPLAN Model
TRANPLAN is a large-scale, integrated set of computer programs offering,
within a single package, comprehensive capabilities for transportation planning,
encompassing forecasting capabilities for both highway and transit networks.
TRANPLAN is designed to evaluate planning areas with up to 3,000 zones and 32,000
highway links. The modeling system includes an interactive graphics network
editing capability, and a large range of plotting capabilities. TRANPLAN is
currently maintained, and used exclusively for regional planning in the Tucson
metropolitan planning area (which includes Marana) by the Pima Association of
Governments Transportation Planning Division (PAGTPD). PAGTPD devotes
considerable manpower and capital resources to the maintenance and operation of
TRANPLAN, and the upkeep of the regional database required for forecasting travel
demand. TRANPLAN is a complex modeling systern, and its use requires
considerable expertise which can only be obtained at the expense of training by
knowledgeable professionals and many hours of hands-on experience.
" The RFP states that a microcomputer version of TRANPLAN for the Town of
Marana be a product of this product. However, the RFP does not indicate whether
or not the $60,000 project budget includes the cost of the purchase of TRANPLAN
and the computer equipment necessary to operate the modeling system. It has been
indicated that the Town of Marana does have some microcomputing capabilities.
However, it is not known if these capabilities are sufficient to operate the modeling
system.
A complete description of the recommended T'RANPLAN software, optional
software, minimum recommended computing system, and optional system
enhancements is contained in Chapter 14 of this proposal. The minimum
recommended software system will cost $2,500, and the minimum recommended
computer system to operate TRANPLAN is available at an approximate additional
cost of $5,800. 'This yields a potential total cost of the recommended software and
hardware system of $8,300. Hardware costs to Marana could be less depending on
the type of computing capability currently possessed. Enhancements to the
software and hardware system could add an additional $12,400 to the price of
TRANPLAN capability.
3-4
~.....~~_.~~_~..,..~~..uµ~.,~.~.v_~.u_~.,~.. _
i
The potential total cost of TRANPLAN and the recommended hardware could
significantly reduce the budget available for this project to produce other requested
products. T'he resources required to produce the other requested products, at a
desirable level of detail, are substantial. Therefore, the use of a portion of the
budgeted funds to purchase and instali TRANPLAN in Marana would significantly
reduce the planning and engineering activities of this project. Also, given the
current size of the Marana area and the current level of population and employment,
it would appear that all of the modeling activities required by Marana for the
foreseeable future could be efficiently and capably handled to PAGTPD, once this
project was completed.
Therefore, it does not appear that the cost associated with the purchase of
TRANPLAN, the recommended hardware, and the devotion of Town staff to
TRANPLAN use would be necessary expenses at this time. However, JHK is
prepared to provide Marana with a microcomputer version of TRANPLAN and the
computer hardware if this is considered a requirement of performing this project.
" In consideration of the above stated factors, JHK has approached this proposal
in a slightly different fashion. The proposed workplan and the associated budget are
based on JHK's recommendation for Marana not to purchase TRANPLAN at this
time, but rather to use the microcomputer version of TRANPLAN at the JHK
Tucson office to perform the modeling and produce the support data in
microcomputer files. The microcomputer files could be turned over to Marana for
use with TRANPLAN if it were purchased at a later date, and these data files would
be incorporated into PAGTPD TRANPLAN files for use with any subsequent
modeling and planning activities.
JHK would use the available funds to provide enhanced planning and
engineering activities. However, JHK has also provided in this proposal a revised
budget, and level of effort by task, assuming that TRANPLAN and some computer
hardware are purchased under this contract. If TRANPLAN is to be purchased
within the study budget, selected project activities will be subject to minor revision
in order to stay within the overall budget limit. If it is determined by the consultant
selection commitee that TRANPLAN, and the required computer
3-5
hardware must be supplied by this project under the $60,000 budget limit, then the
revised budget and level of effort by task should be considered with this proposal.
Note that the elements of this study approach that are considered candidates
for elimination or reduction in scope, if the option to purchase TRANPLAN and
computer hardware is selected, are highlighted in Exhibit 3-1.
Transportation Modeling Within a Regional Context
It is vital that the transportation modeling for the Town of Marana study area
be coordinated with the regional modeling system maintained by PAGTPD in order
to establish a high level of consistency and credibility in the results. This
coordination must include the transportation and land use goals, objectives, and
policies as expressed in the Town of Marana General Plan. Exhibits 3-2 and 3-3
show the transportation circulation element and land use elements of the General
Plan. The coordination must occur at three levels:
o The transportation analysis zone (TAZ) structure.
o The distribution of the population, employment, and other socioeconomic
data for the study area.
~ o T'he transportation network structure.
The TAZ Structure
The P/~GTPD regional TAZ structure for the study area is shown in
Exhibit 3-4. This existing TAZ structure is too coarse to perform transportation
modeling at the desired level, except for the areas in the southeast corner of the
study area. Using the land use pattern described in the General Plan as a guide, the
zone structure of the study area will be redefined at a level commensurate with the
desired detail for transportation modeling. The General Plan zonal land use system
has already been configured within the context of the circulation system and will
easily convert to a redefined TAZ system. It is also very important that the
redefined TAZ system for the study area aggregate to the existing PAGTPD TAZ
system to facilitate use of the PAGTPD socioeconomic database and conversion of
the Marana zone configuration to the PAGTPD modeling system.

It should be noted that the project study area extends beyond the influence
area defined in the Marana General Plan both to the north across the Pinal County
line, and to the west. The appropriate land use assumptions for the area beyond that
defined in the General Plan will be made after discussions with officials of the Town
of Marana and Pinal County, and after coordination with the consultants responsible
for the development of the General Plan. These assumptions will most likely be
similar to those already made for the perimeter areas of the General Plan land use
pattern.
Distribution of Socioeconomic Data
The PAGTPD Year 2010 forecast for the population growth in the Marana
study area will be used as the base condition for the 20-year time period. The
distribution of the Year 2010 population and employment data throughout the study
area wili be determined considering the current PAGTPD distribution assumptions,
the General Plan land use pattern, developer plans for the study area, and the
~ current distribution of activities.
„ Alternative scenarios to the PAGTPD Year 2010 forecast totals for the study
area will be considered only if it is determined that the Marana growth policy, as
expressed in the General Plan, differs significantly from the PAGTPD assumptions.
The inclusion of portions of so~thern Pinal County in the study area will also be
reviewed to evaluate its affect on the magnitude and distribution of the
socioeconomic data in the modeling process.
The IO- and 15-year transportation improvement programs will be based on
scaled down versions of the Year 2010 population and employment forecasts, with
consideration of the existing conditions, and staged land use developed. The five-
year distribution of activities will be based on a trend analysis of the current
conditions, taking into consideration the General Land Use Plan and the current
development plans for the area. JHK will coordinate the land use development
scenario with the consultant that performed the General Plan land use analysis to
ensure consistency, and aid in the identification of the "most likely" land use
, scenario for each time period.
3-10
The HiQhway Network
1'he PAGTPD modeling representation of the existing and Year 2010 highway
network in the Marana study area are shown in Exhibit 3-5. A comparison of the
PAGTPD Year 2010 network to the Marana Circulation Plan in Exhibit 3-2 shows
considerable difference in the network assumptions. The JHK Project Team
proposes to use the Circulation Plan as the base condition for the long-range
transportation alternatives in the study area. Potential changes in the Circulation
Plan may be identified as the Plan is subjected to evaluation and review. The
Circulation Plan will be tested utilizing the PAGTPD Year 2010 socioeconomic
database to determine if it is relevant to the 20-year transportation needs. At least
two other long-range alternatives will be proposed, evaluated, and critiqued in
comparison to the Circulation Plan.
The study area extends beyond the PAGTPD regional planning area to the
north into Pinal County. This impacts the network and the travel assignment in the
PAGTPD modeling system in that the Marana Study area extends beyond the
~ northern external trip node used in the PAGTPD modeling system. The external trip
node must be moved north of the northern boundary of the study area, and the
' number of external trips adjusted to reflect the inclusion of the interchange
between I-10 and Marana Air Park Road in the study area. This can be accomplished
with relative ease given knowledge of the existing traffic accessing and egressing
I-10 at Marana Air Park Road, and a review of the 1983 PAGTPD External Travel
Survey.
Use of the PAGTPD Modeling System-TRANPLAN
It was indicated in discussions with PAGTPD staff that three alternatives were
avaiiable for the use of TRANPLAN:
o PAGTPD operates TRANPLAN and inputs all data as provided by the
consultant.
o PAGTPD supplies the consultant with "log-on" access to its computer
system where the consultant manipulates the data, and PAGTPD operates
TRANPLAN.
o The consultant establishes TRANPLAN on an independent computing
system along with the rnost recent versions of the existing and Year 2010

highway network and socioeconomic databases supplied by PAGTPD,
manipulates the data, and operates the modeling system.
In each of these operating scenarios it is highly desirable that PAGTPD
provide a review of all model input and output used in the project, and review the
consultants interpretation of the modeling results.
'fhe JHK Project Team is in an excellent position to supply consultant services
utilizing the latter alternative for the operation of TRANPLAN. JHK has, in its
Tucson office, both the TRANPLAN modeling system and the PAGTPD network and
socioeconomic databases necessary to perform this study. JHK has extensive
experience in the use of this model and the manipulation of the PAGTPD data from
its work on the I-10 Corridor Study for ADOT. The ~HK Project Team is ready to
proceed with the modeling with no wasted effort learning the modeling system or
gaining familiarity with the database, and believes that running the modeling system
in its 7ucson office will provide the most efficient means to conduct this study, and
ensure a timely delivery of project products. This also puts JHK in the best possible
, position to deliver a microcomputer version of TRANPLAN and the data files for its .
use.
It is also the intent of the JHK Project T'eam to review modeling assumptions,
data input, and model output with PAGTPD staff to ensure the integrity and
consistency of the JHK version of TRANPLAN. Note that this is the working
relationship that JHK has established with PAGTPD for the performance of the
ongoing I-10 Corridor Study for ADOT, and that the JHK microcomputer version of
TRANPLAN was validated by PAGTPD staff.
Transportation Planning Coordination
The Marana study area extends beyond the current boundaries of the town and
includes portions of the transportation system under the jurisdiction of the Arizona
Department of Transportation, Pima County and Pinal County. The study area also
encompasses large areas of state land, and includes a small portion of the Saguaro
National Monument along its southern boundary. The entire study area is also
included in the metropolitan Tucson regional planning area as defined by the Pirna
Association of Governments (PAG). Marana along with Oro Valley, the City of
3-13
Tucson, South Tucson, and Pima County comprise the PAG membership. Elements
of the adopted regional transportation plan must be approved by the PAG members.
Other planning or engineering studies that affect the study area have either
been completed recently or are currently underway. Exhibit 3-6 provides a list of
these studies. The results of several of these studies have patential major impacts
on the Marana area.
Therefore, it is vital that transportation planning aspects of this study be
coordinated with the public agencies, as well as the private interests affected, and
be pursued in light of the other studies that will impact the study area. JHK is in a
particularly advantageous position to provide this coordination because of its
involvement in other studies that could have a major impact on the Marana area.
The I-10 Corridor Study will provide recommendations for the future development of
I-10 through the Marana area, which will include the number of mainline lanes, the
use of continuous frontage roads, and the location of interchanges. The BAJA
project will provide a comprehensive transportation plan for the entire Tucson
, metropolitan planning region, including the Marana study area. JHK's primary
w responsibilities on the Baja project include the evaluation of the transportation
system, modeling transportation system alternatives using TRANPLAN, and
providing the expertise in transportation engineering at public meetings.
The JHK Project Team will provide the appropriate coordination between
public and private interests, and other transportation studies through a series of
workshops, meetings, and a review of the pertinent study literature. A preliminary
list of the public agencies and private concerns that may have an interest in this
study is given in Exhibit 3-7.
Subtasks have been included in the project study approach which are devoted
to workshops and meetings with the various project interest groups. These meetings
and workshops will occur throughout the duration of the project and will be used to
disseminate and gather information. The first workshop will be with the Steering
Committee for this proje~t to identify issues and refine the workplan. JHK will hold
a public meeting early in the study process to identify the study goals and
objectives, and gather information on public concerns and issues. JHK will
interview public agency personnel and enurnerate the planning coordination issues

and concerns. Meetings with local developers wil! also be conducted to review
development and area plans. The project Technical Panel will review the
transportation plan for the study area and identify the opportunities and constraints
to plan implementation.
As the transportation plan is developed more fully, a second public meeting
will be held to review the preliminary findings and solicit public input. A final
public meeting will be held to present the Master Transportation Plan and gather
public response.
Opportunities and Constraints
'fhe establishment of a transportation master plan for areas with relatively
few existing roadway alignments requires the consideration of a wide range of
feasibility issues. Issues that need to be considered include terrain, soil conditions,
, environmental sensitivity, drainage and hydrological implications, current approved
private and public plans, and opportunities for transit implementation. To ensure
that these issues are incorporated into the planning process, the JHK Team will
devote a significant effort toward defining opportunities and constraints to elements
of the circulation system to be recommended in this study. Workshops will be held
with representatives of public and private organizations as well as from technical
disciplines to obtain insights into circulation plan feasibility.
The JHK Project Team includes a panel of local technical experts in the areas
of environmental impacts, drainage/hydrology, geotechnical engineering,
archaeological/cultural resources, and transit planning. The panel consists of the
following individuals:
P. Scott Den-Baars Geotechnical Engineering GRC Consultants
Steven R. Walker Drainage/Hydrology Water Resource Engineering
Mary Lou Heuett Archaeological Resources Cultural and Environmental
Services, Inc.
Mary L. Rodin Environmental Assessment JHK dc Associates
Larry Sauve Transit Planning JHK bc Associates
3-17 •
The panel will prepare a brief evaluation of the proposed transportation plan
to identify opportunities and constraints for plan implementation.
Recommendations will be proposed to mitigate problem areas, and if particular
constraints appear to severely limit the feasibility of plan implementation,
alternatives will be recommended.
Validating the Model
Current development is generally sparse except for a cluster of TAZs in the
southeast corner of the study area, and for the area defined generally by TAZ 421
within the Marana town limits (see Appendix B for 1987 PAGTPU data). The
existing levels of development combined with the coarse TAZ structure over rnost of
the study area pose a concern in terms of validating the model for the existing
conditions.
. JHK proposes to validate the model through the following process:
o A new zone structure for the study area will be established based on the
factors previously discussed.
o The existing population and employment will be redistributed as necessary
to the new zone structure, based on aerial photographs of the study area,
previous land use studies, and field surveys as required.
o The 1987 PAGTPD network for the study area will be reviewed and
updated based on current maps, and field surveys as required. JHK
proposes to video log the highway system in the study area as an
additional means of updating this information.
o Traffic counts will be provided by the Arizona Department of
Transportation at a reasonable number of locations to establish the basis
for model validation using screenlines and cordons.
o The modeling system will be run with the existing network and database
and the output will be compared to the ground counts.
o Adjustments in the model parameters and database will be made as
required to obtain a reasonable level of consistency between the ground
counts and the model estimates of the existing conditions in the study
. area.
3-18
This procedure will result in a modeling system that is sufficiently accurate
for the purposes of this study. There is no anticipated need to attempt to
recalibrate the trip generation or trip distribution models for the Marana study area.
The assumption will be made that residents of the study area, as an element of the
regional planning area, will travel and respond to land use development in a manner
consistent with that of the population for the entire region. Therefore,
recalibration of the models should not be necessary.
Funding for Transportation Improvements
Often the cost of impiementing recommended transportation plans exceed
current and future funding levels. Therefore, the JHK Team will investigate and
document possible funding sources to construct and maintain transportation
facilities. Several alternatives that have been used as funding mechanisrns include
local sales tax, local payroll tax, developer fees and charges, benefit assessrnent
district, and tax increment financing. Potential revenues to be gained from various
: funding mechanisms will be analyzed in the study and compared with projected .
construc*.ion and maintenance costs for implementing the transportation plan
; recommendations. It is anticipated that a combination of funding sources will be
needed to produce the required revenues.
Street Design Standards
The establishment of design standards in a circulation element is considered by
JHK to be an often overlooked factor. The JHK Project Team will make a
significant effort to ensure that details related to roadway cross section, provision
for bicycle and pedestrian modes, provision for underground and overhead utility
placement, and such factors as landscaping and aesthetic treatments are considered
in developing the overall plan. By placing emphasis on these "design details" at an
, early stage, the Town of Marana will be better able to implement new and improved
roadway in a manner which meets Town objectives.
3-19
A key element of the transportation master plan will be the development of
street design standards to guide future road development. Design standards will be
based on ADOT, Pima County, City of Tucson, and AASHTO guidelines and policies,
and consideration of the Marana goals and objectives for the Circulation Plan. JHK
is familiar with the newly revised AASHTO design standards (the Green Book) and
guidelines and has used AASHTO standards to develop numerous design criteria for
freeways, urban/suburban arterials, and rural roads. JHK is also familiar with
ADOT and Pima County standards which have been used in numerous traffic studies.
Transit Modeling and Planning
Existing transit service to the study area consists of the Ina Road express
service to downtown Tucson and the University of Arizona, and the Huges Aircraft
shuttle. Both of these routes extend only to the southern boundary of the study area
along Ina Road east of I-10 providing extremely limited service. For the Year 2010,
the PAGTPD database assumes that some transit service will be provided to the
= southeast quadrant of the study area as indicated in Exhibit 3-8. However, inherent
to the PAGTPD modeling process is the assumption that approximately 20 percent
~ of the person-trips generated in the portion of the study area indicated to have
transit service will be made by transit. This assumption is based on a regional goal
of obtaining a six percent transit mode split by the Year 2010. Current regional
transit ridership is between one and two percent of all person-trips.
From a modeling perspective, the impacts of the assumed levels of transit
ridership must be evaluated with respect to its affect on the need for roadway
improvements. This can be accomplished by evaluating the affect of maintaining
the status quo in transit ridership for the study area. In addition, imbedded in the
PAGTPD modeling system are assumptions concerning the level of ridershare
activity for the study area in Year 2010. The impact of these assumptions on the
evaluation of transportation needs must also be examined. JHK is familiar with
these assumptions and has performed similar evaluations for the I-10 Corridor Study.
From a planning perspective, the potential for developing a transit circulation
. system for the study area with connections to the regional transit system should be
investigated. This, and other transit alternatives, will be considered by Mr. Larry

and has performed similar small-area transit evaluations. Mr. Sauve will formulate
transit service concepts for the study area and evaluate their service potential
based on the distribution of population and activities.
STUDY APPROACH
1'ask 1 Prepare Detailed Workplan
Subtask 1.1 Steering Committee Workshop The JHK Project Team will
conduct a workshop with the project Steering Committee to identify the issues,
concerns, and work elemen#s that require modification in the proposed workplan
presented here.
Subtask 1.2 Revise Proposed Workplan The proposed workplan will be
revised based on the comments and suggestions from the Steering Committee. A
draft final workplan will be prepared for presentation at the first public meeting.
Subtask 1.3 Conduct Public Meeting. JHK will advertise, conduct, and
~ document a public meeting in the Town of Marana. The purpose of this initial
meeting will be to present the project goals and objectives, and solicit public input
on the issues and concerns that should be incorporated into the project workplan.
Subtask 1.4 Prepare Final Workplan. JHK will incorporate the comments
and concerns of the project Steering Committee and the public into the final
workplan. The final workplan will be furnished to the Steering Committee for
approval.
Task 2 Inventory of Existing Conditions
Subtask 2.1 Assemble Existing Roadway and Traffic Data Through contacts
with ADOT, PCDOT, PAGTPD and the Town of Marana, JHK will assemble the
existing roadway and traffic data. The data sought will include information on
jurisdictional responsibility, functional class, roadway geometrics, location of
traffic signals, recent traffic counts, intersection turning movements, vehicle mix,
3-22
posted speed limits, accident data, and information on pavement condition. This
information will supply the basis for establishing the existing roadway and traffic
conditions in the study area.
Subtask 2.2 Video LoQ ExistinQ Hi~hway Network JHK will video tape the
existing highway system in the study area for all roadways considered to be of
functional class collector and above. That is, local streets will not be taped. The
portion of I-10 that traverses the study area will not be included in the video log
because it is under the jurisdiction of the State and could not become an element of
the highway system under Marana jurisdiction.
Each mile of roadway will be taped in both directions of travel through the
windshield of a moving vehicle. This technique has worked well in previous JHK
studies, and provides an excellent means to inventory roadway and roadside
conditions. The tapes will be edited and indexed to show the roadway name and
direction of travel on the tape. A written index of the tape will be provided
. indicating the location of each roadway segment on the tape.
Subtask 2.3 Perform Traffic Counts. JHK will identify those locations
where traffic and turning movement count data are required to validate the
modeling system and evaluate the short-term transportation system needs. As
indicated in the RFP, this data will be collected by ADOT and furnished for the
project. JHK will schedule the performance of these traffic counts with ADOT.
Subtask 2.4 Assemble PAGTPD Databases. JHK currently has, in its Tucson
office, PAGTPD databases representing the 1987 and 2010 highway network and
socioeconomic data used with the 'fRANPLAN modeling system. These data are
being used for the I-10 Corridor Study. The Project Team will determine whether or
not these represent the most current data available from PAGTPD, and if not, the
' updated versions will be obtained. It should be noted that through the work on the
I-10 Corridor Study JHK has generated the most up-to-date configuration of I-10 in
3-23
the regional network, and therefore the networks used in this study will include the
recommended alternatives for I-10 which may impact the study area.
Subtask 2.5 Assemble Relevant Planning and Engineering Studies The JHK
Project Team has identified a preliminary list of the planning and engineering
studies that are relevant to this project. These are shown in Exhibit 3-6. Much of
this information has already been accumulated in the JHK Tucson office as a result
of work on other projects. Meetings with the public agencies identified in
Exhibit 3-7 will be held to complete the inventory of this material.
Subtask 2.6 Assemble Existing Land Use Data and Development Plans JHK
will assemble the existing land use data from a review of the aerial photographs to
_ be supplied by ADOT, from PAGTPD databases, and from a compilation of previous
and ongoing plans and studies. Development plan information will be obtained for
' Pima County, from the Town of Marana. The Marana General Plan also contains
existing land use data as shown in Exhibit 3-9. Pinal County will also be contacted
to determined if any plans or data are available for the portion of the study area
north of the county line.
In addition to the assemblage of data from the above mentioned sources, JHK
will meet with developers that have approved plans, or are developing plans for the
study area. This will ensure the most up-to-date land use data available and
facilitatE the evaluation of both short and long-term needs.
Subtask 2.7 Assemble Revenue and Funding Data Data on the levels of
existing funding for highway improvements will be gathered from the Marana
Managers Office, and from Pima County. Forecasts of the future revenues from
taxes and the lottery will be gathered from the State. This information will be used
to assess the funding needs to support the elements of the Master Transportation
" Plan.

Task 3 Review Plans and Programs
Subtask 3.1 Review Roadway and T'raffic Data The roadway and traffic
data will be reviewed to facilitate the definition of the existing network conditions.
This data will be compiled for use in validating the TRANPLAN model for the study
area, and to determine if additional field data collection is required.
Subtask 3.2 Review Video Tapes and Verify Existing Network The review of
the video tapes will be used to verify the data describing the existing network in the
study area. Roadway geometry information and intersection control data taken
from the videos will be used to update the 1987 PAGTPD database for the study
area.
Subtask_ 3.3 Review Previous and OngoinQ Studies Data from previous and
ongoing planning and engineering studies wil! be used to update the PAGTPD 1987
database, and revise the Year 2010 database as appropriate. This will include both
information on the network and the distribution of activities affecting the study
area. This information will also be use to evaluate the short and long-term
transportation development and needs affecting the study area.
Subtask 3.4 _ Review Land Use and Development Plans The existing land use
and development plans will be reviewed and summarized in comparison to the 1987
and Year 2010 PAGTPD socioeconomic databases. The distribution of the existing
and Year 2010 forecast activities will be updated as appropriate. This information
will supply the basis for TRANPLAN validation, and for the evaluation of the future
' transportation system needs.
3-26
Subtask 3.5 Review and Update PAGTPD Databases. The PAGTPD data-
bases will be compared to the data that is collected, for both the 1987 and 2010
time periods. The 1987 network and socioeconomic data will be updated as
necessary to provided the most current representation of existing conditions for the
study area. PAGTPD assumptions of the 2010 condition will be reviewed in light of
the current development patterns, planned development, and the General Plan land
use policies. This review will be performed at the TAZ level. An evaluation of this
type was performed by JHK for the I-10 Corridor study, which included the Marana
study area. An example of how this analysis was accomplished is given in
Exhibit 3-10. Virtually all of the Marana study area has already been reviewed by
JHK in this manner. The updated socioeconomic databases will be used as the basis
for the establishment of the "most likely" development scenarios.
Subtask 3.6 Establish "Most Likely" Development Scenarios Through the
review of the data, the existing and planned land use developments, the Marana
" General Plan land use policies, and through discussions with Marana officials, Pima
. County staff, and PAGTPD staff, JHK will devise a set of development scenarios for
the five-, 10-, 15- and 20-year time periods. This effort will also be coordinated
with the consultant that performed the . General Plan study. The "most likely"
development pattern for each time period will be used to develop the desired
transportation improvement programs and plans.
Subtask 3.7 Technical Panel Workshop The first technica! panel workshop
will be held immediately following the development of the land use scenarios. This
workshop will be used to review the data describing the study area with the panel
and establish an initial assessment of the opportunities and constraints to
transportation development. This assessment will include geotechnical,
archaeological/cultural, drainage/hydrology, environmental and transit related
issues.

Subtask 3.8 Identify Short-Term (Five-Year) Needs. JHK will identify the
short-term transportation system needs based on the review of the current traffic
conditions, land use development patterns and plans, and an assessrnent of the short-
term roadway capacity and level o# service in the study area. JHK has already
performed this type of analysis for a small portion of the study area in a recent
PCDOT study. The results of the PCDOT study are shown in Exhibit 3-11 for those
intersections and roadway segments in the Marana study area. Using the traffic
count data supplied by ADOT, JHK will evaluate the remainder of the study area in
a similar fashion and provide improvement recommendations.
Other factors to be reviewed for the development of the short-term
improvement program will be pavement condition, as judged from the video tapes,
and traffic accidents. Traffic accident data for Pima County roadways is compiled
and published annually by PCDOT. JHK will review this data with PCDOT staff and
identify intersections and roadway segments of concern that are within the study
area. Accident history for the Town of Marana will be obtained from ADOT for the
. most recent three years of data.
~ Subtask 3.9 Prepare Working Paper. The JHK Project Team will prepare a
working paper which documents the results of Tasks 1 through 3. The working paper
will be submitted to the Steering Committee for review and comment.
Subtask 3.10 SteerinQ Committee Workshop JHK will present the results of
Tasks 1 through 3 to the Steering Committee. JHK will document the Committee's
questions, concerns, and suggestions for incorporation into the final products of this
project.
Task 4 Implement TRANPLAN
JHK has procured the assistance of Mr. Edward Granzow, of UAG, to ensure
that the implementation and use of TRANPLAN progresses as smoothly and

efficiently as possible. UAG is the proprietor of TRANPLAN, and Mr. Granzow is
the creator of many of its elements. Mr. Granzow will be used in an advisory
capacity on an as-needed basis.
Subtask 4.1 Redefine Traffic Analysis Zone (TAZ) System JHK will
redefine the PAGTPD TAZ system for the study area such that the zone size is
small enough to produce the desired level of accuracy in the traffic assignment.
The General Plan zonal land use system will provide the basis for redefining the TAZ
system. The new zone system will be defined such that it will aggregate easily to
the existing PAGTPD system. This will allow a smooth transition between the to
systems and facilitate the record keeping of the socioeconomic data. The new zone
system will be input to the TRANPLAN model.
Subtask 4.2 Update and Redistribute Years 1987 and 2010 Socioeconomic
Data. The 1987 and the Year 2010 socioeconomic databases will be updated based
on the previous review of this material. The Year 2010 database will be adjusted to
~ represent the "most likely" development scenario evaluated in an earlier task.
_ The 1987 and the Year 2010 database will be redistributed to the redefined
zone system. The 1987 database will be used to validate the model on the existing
network, and the Year 2010 database will be used to assess the long-range
transportation needs.
Subtask 4.3 Update 1987 Network. The PAGTPD 1987 network will be
updated as required based on a comparison of the database to the actual network
configuration. This update will consider such factors as network configuration,
number of lanes on each roadway link, travel speeds, capacity and intersection
control. Another important element of this update wil! be the definition of the new
TAZ centroid connectors for the network.
Subtask 4.4 Define Trip Productions and Attractions by TAZ The trip
generation of the redefined zone system will be evaluated with the constraint that
the total trip productions and attractions for the Years 1987 and 2010
socioeconomic data must be the essentially the same as under the present PAGTPD
3-31
TAZ system. Differences will occur if the PAGTPD databases are altered in the
review and update process. The most efficient method of generating the trip
productions and attractions for the new zone system is to use the PAGTPD trip
generation model. JHK has the PAGTPD trip generation model in its Tucson office.
The Project Team will establish the T'AZ input parameters to the trip generation
model and use the model to calculate the trip productions and attractions for the
redefined TAZ system. 1'he results for the Years 1987 and 2010 databases wil! be
compared to the present PAGTPD generated productions and attractions to ensure
that they are consistent with the changes in the data.
Subtask 4.5 Distribute and Assign 1987 Trips The 1987 trip productions and
attractions will be distributed and assigned to the 1987 network using TRANPLAN.
The output will be compared to previous PAGTPD data along major arterial
roadways such as I-10 and Ina Road to ensure consistency in the modeling effort, and
Beta test the network and socioeconomic data entries.
~ Subtask 4.6 Validate Model Output The 1987 traffic assignment for the new
, TAZ system will be compared to traffic counts at strategic screenlines to validate
the model.
Subtask 4.7 Refine Model Parameters. The model input parameters will be
refined as indicated by the validation step in subtask 4.6. Subtasks 4.6 and 4.7 will
be repeated until an acceptable level of agreement is obtained between the model
results and the traffic counts.
Subtask 4.8 Prepare Working Paper A working paper will be prepared
describing the activities and results of Task 4. The working paper will be submitted
to the Steering Committee for review and comment.
Subtask 4.9 Steering Committee Workshop JHK will present the results of
Tasks 4 to the Steering Committee. JHK will document the Committee's questions,
concerns, and suggestions for incorporation into the final products of this project.
3-32
Task 5 Determine Street Development Standards
Subtask 5.1 Review ExistinQ Standards and Practices The Project Team will
review the existing standards and practices for roadway development for Pima
County, Pinal County, Marana, ADOT, the City of Tucson, and AASHTO. It is
important to review the county standards because much of the study area is
currently under county jurisdiction, and it would be beneficial to incorporate
consistency into the future roadway development. The review will catalog current
standards and practices by roadway functional classification, for example arterials,
collectors and local streets.
Subtask 5.2 Establish Recommendations for Street Development Standards
JHK will recommend street development standards for Marana by the functional
classification of the roadway. It is anticipated that the standards will be based on
ADOT, Pima County, and City of Tucson design standards, as they apply to the
Town's needs, and the policies set forth in the 1987 Marana General Plan. Street
• design information will be provided in the form of typical cross-sections for each
functional class of roadway, and will include number and width of lanes, median
width, bike lane location and width, sidewalks, and typical right-of-way width as
appropritate. This information will provide for consistent design treatments as new
roads are developed and existing roads are improved.
JHK will also formulate recommendations for other key design areas such as
driveway and median access spacing, and design storm frequencies to be used for
drainage design.
Subtask 5.3 Prepare WorkinQ Paper JHK will prepare a working paper
describing the activities and recommendations resulting from Task 5. This working
paper will be submitted to the Steering Committee for review and cornment.
Subtask 5.4 Steering Committee Workshop JHK will present the results of
Tasks 5 to the Steering Committee. JHK will document the Committee's questions,
concerns, and suggestions for incorporation into the final products of this project.
3-33
Task 6 Develop and Test Area Transportation Plans
Subtask 6.1 Identify Goals, Objectives, and Standards JHK will identify the
goals and objectives of the Master Transportation Pian based on the interaction with
the public, the Steering Committee, and the Technical Panel, and through
incorporation of the goals, objectives and policies that are presented in the General
Plan. The goals, objectives and policy statements concerning the (l~Iarana circulation
system are given in Exhibit 3-12. JHK will incorporate these statements into the
development of the #ransportation plans generated through this project.
The operating standards for evaluating the required size and number of
roadways to be recommended will be set as a matter of Town of Marana policy.
Typical operating standards for urban signalized intersections is level of service D,
and level of service C is the typical standard for arterials and collectors between
intersections. JHK will use these policy standards in the evaluation of the
transportation needs of the Marana community.
~ Subtask 6.2 Identify Opportunities and Constraints Through a second
~ workshop, the Project Team will define the opportunities and constraints for
~ transportation system development within the study area based on the "most likely"
development scenarios proposed, and the review of previous and ongoing planning
and engineering studies affecting the study area. The Marana area is particularly
sensitive to flooding because of its location relative to the Santa Cruz River, and
the large portions of the study area are subject to sheet flow. The impact of these
drainage and hydrology issues will be evaluated with regard to the implementation
of the circulation system presented in the General Plan. Also of concern, is the
potential impact of the Central Arizona Project canal locations on transportation
system development in the study area. Similar evaluations will be made with
respect to geotechnical, environmental, and archaeological/cultural issues.
Of particular importance will be the evaluation of the potential for transit
service. Currently the study area is served by a single express route along Ina Road
that travels to the Tucson downtown area and to the University of Arizona.
Considering the forecast growth for the study area their may be opportunities to
expand the regional transit service, or establish a Iocalized circulation type

MARANA GENERAL PLAN GOALS, OBJECTIVES,
AND POLICIES FOR THE CIRCULATION ELEMENT
OBJECTIVE
Develop multi-purpose use arterial roads, to enhance view orientation, provide
buffers between land uses and to act as drainage barriers.
Policy
Encourage the private ownership and maintenance of neighborhood street
systems within established subdivisions.
Policy
Assist developers in establishing reimbursement agreements for fair share pay
back of constructed streets and utilities.
Program
. Assist in funding of major street construction and utilities. .
° OBJECTIVE
Assist in the expansion of Avra Valley Airport.
Policy
Influence Pima County in the location of Tangerine Road, Sanders Crossing,
the Airport expansion, and the Santa Cruz River Park trails.
Policy
Develop an intergovernmental agreement with Pima County to provide for a
comprehensive circulation/transportation plan.

transit system. These and other opportunities will be examined by Mr. Larry Sauve
of JHK, who has extensive transit planning experience.
Subtask 6.3 Develop LonQ-range (20-year) Concepts. The circulation
element of the General Plan will be used as the base condition in the formulation of
the long-range transportation concepts the study area. Alternatives will be
generated as constraints dictate the need for change, and as opportunities indicate
the potential for improving on the circulation plan. It is anticipated that the
circulation plan and at least two alternative concepts will be designed for initial
testing using the TRANPLAN modeling system.
Subtask 6.4 Model and Evaluate Lon~-ranQe Concepts. The alternative long-
° range transportation system concepts will be modeled using TRANPLAN and
- evaluated to determine their effectiveness in meeting the goals and objectives of
~ the community. The evaluation will be based on several measures of effectiveness
including such factors as:
o Lane miles of roadway required
o Potential operating levels of service
o System implementation cost
o Vehicle miles of travel within the study area
o Potential environmental impacts
o Feasibility of implementation
o Conduciveness to transit service
o Impact on Marana quality of life
o Potential to disrupt existing development
Based on the results of this analysis, the alternatives may be adjusted,
modeled, and evaluated again. The result will be a recommended circulation plan
scaled to the anticipated study area needs for the Year 2010.

JHK has procured the assistance of Mr. Edward Granzow, of UAG, to ensure
that the implementation and use of TRANPLAN progresses as smoothly and
efficiently as possible. UAG is the proprietor of TRANPLAN, and Mr. Granzow is
the creator of many of its elements. Mr. Granzow's role in this study will depend on
whether or not the option to purchase TRANPLAN is selected.
Subtask 6.5 Develop Intermediate Transportation Plans. Intermediate
transportation phasing scenarios will be developed for the 10 and 15 year time
periods, based on the "most likely" development patterns established in earlier tasks,
and the recommended circulation plan for the 20-year time period. This will be
accomplished by scaling back the 20-year transportation system needs to match the
development patterns for the 10- and 15-year time periods.
Subtask 6.6 Prepare Working Paper. JHK will prepare a working paper
describing the activities and recommendations resulting from Task 6. This working
° paper will be submitted to the Steering Committee for review and comment.
- Subtask 6.7 SteerinQ Committee Workshop. JHK wil! present the results of
Tasks 6 to the Steering Committee. ~HK will document the Committee's questions,
concerns, and suggestions for incorporation into the final products of this project.
Whcn the elements of the transportation plans presented in the working paper are
approved by the Steering Committee, they will be prepared for presentation at a
public meeting.
Subtask 6.8 Public irleeting. JHK wil! advertise, conduct and document a
public meeting in the Town of Marana where the elements of the recommended
transportation plans will be presented. Suggestions, comments and criticisms will be
considered in a reevaluation of the plans.
Task 7 Produce Draft Master Transportation Plans
Subtask 7.1 Draft Report. JHK will incorporate the working papers,
Steering Committee comments, Technical Panel evaluation, and public comments
3-39
into a draft of the final report. The report will detail the development of the
recommended transportation plans, and the roadway development standards.
Subtask 7.2 Steering Committee Workshop. The draft final report will be
presented to the Steering Committee for review and comment. Upon approval of
the Steering Committee the draft final report will be prepared for presentation at a
public meeting.
Subtask 7.3 Public Meeting. 7HK will advertise, conduct and document a
public meeting on the draft final report in the Town of Marana.
Task 8 Develop Final Master Transportation Plan
JHK will revise the draft final report based on the comments and suggestions
of the Steering Committee, and the comments received at the public meeting. The
result will be the Master Transportation Plan for the Town of Marana, which will
: include a short-range (5-year) capital improvement program, intermediate-range (10
• and 15-year) transportation development plans, a long-range (20-year) transportation
- plan, and a set of street development standards.
JHK will provide sixty (60) copies of the final report, one hundred (100) copies
of the executive summary, and a reproducible master of each.
