Obligation Bond Program, Project No. 12302. Cost: $113,422.00 BACKGROUND: This project was established to design and construct the reconfiguration ofthe existing Belt Line Road/Dallas
North Tollway interchange to act as a single intersection instead of two. The proposed improvements will allow the simultaneous operation ofleft turns for the east/west traffic and north/south
traffic movements. In addition, it is anticipated that there will be a 15-20% improvement in efficiency in this intersection upon completion of the project. The:finn ofCarter & Burgess,
Inc. submitted a proposal, in the amount of $113,422, to perform the first phase ofthe proposed SPill improvements. Through the selection process and submittal of Statements ofQualifications
by several engineering :finns, Carter & Burgess was selected. This first phase will consist ofidentifying and analyzing five geometric and operational approaches that will make a significant
enhancement to the overall traffic operations in the intersection and develop several alternatives for design consideration. Subsequent phases ofthis project will include final design
and construction services. RECOMMENDATION: It is recommended that Council authorize the City Manager to enter into a contract with Carter & Burgess, Inc., in the amount of$I13,422.00,
for engineering services associated with the first phase ofthe Single Point Urban Interchange project.

( Scope of Services Intersection Improvements Beltline Road at Dallas North Tollway September 4, 2001 The scope of services for Intersection Improvements to Beltllne Road at the Dallas
North Tollway includes planning, design and construction phase services. The intent of this scope is to identify and analyze geometric and operational improvernents that will make a
significant improvement to the overall traffic operations of the intersection and along Beltline Road. This scope will use previously conducted studies of this intersection as a basis
for alternatives. These previous studies will be the basis for identifying alternatives; however, new traffic information including traffic counts, changes in land use, and changes in
travel patterns in the immediate area will be included in the analysis. This study will include five alternatives: 1. the:base (existing) condition, also known as the no-build alternative;
. 2. 'one single-point diamond alternative with U-turns, 3. one single-point diamond alternative without U-turns; 4. a traditional diamond interchange alternative with geometric and
operational improvements, and 5. one additional alternative. 􀁁􀁬􀁴􀁥􀁲􀁮􀁡􀁴􀁩􀁶􀁾􀁳 will consider options for pedestrian movements over the Dallas North Tollway and options for aesthetic
enhancements. "1-The City will provide Carter & Burgess all available studies or plans including plans for cityowned utilities and traffic counts or timing plans for intersections along
Beltline Road. Carter & Burgess will obtain relevant studies, traffic counts, plans, etc., from the City of Dallas. Upon completion of the alternatives analysis phase, the City will
select a recommended action for design and construction. Additions to this scope of services will be made for design and construction phase services. Additional right of way may be required
at each of the four corners of the intersection. It may be necessary to relocate City-and Dallas-owned and private or franchise utilities. . Phase 1: Identify and Analyze Alternatives

Fax • Re: Phase I Report for Single Point Urban Interchange Jurisdictional Support Investigation Dear Mr. Whitehead, Attached you will find the Phase I Report to determine the level
of support for the construction of a Single Point Urban Interchange (SPill) at the intersection ofBeltline Road and the North Dallas Tollway, Dallas, Texas. The objectives of Phase I
of the assignment were to determine the level of support for the construction of a SPill at this intersection and to obtain concurrence and approval, if possible, of the project from
the City ofDallas, Dallas County, the Texas Department of Transportation, Dallas Area Rapid Transit, the North Texas Turnpike Authority, and the North Central Texas Council of Governments.
The Coker Company met with representatives from various jurisdictions and the general consensus was that if the SPUI design could effect a measurable improvement in the intersection's
efficiency at a cost that would not be umeasonable for the traffic improvement created, that the project should be pursued. None of the jurisdictions put their position in writing, but
the attached report provides a synopsis of discussions, issues, and opinions from the interviewees about the proposed project. During discussions with the jurisdictions, we did discuss
funding opportunities and potential jurisdictional funding support. My impression is that the City ofDallas is inclined to participate at some, unspecified level in the construction
of the intersection since it is in the City of Dallas. Dallas County indicated that any funding for the next three years has already been prioritized and would not likely be assigned
to this project. DART indicated that the Town of Addison has received their allocation ofDART related funding and that the Town may allocate a portion ofthis funding to this project
in accordance with the standards and requirements of the funding agreement. The Council of Governments, as the MPO (Metropolitan Planning Organization) empowered with the distribution
ofTEA 21 funds, indicated that application could be made through that organization, but that project funding may not be available and if funding were made available, that the funding
cycle would more than likely occur following the target dates for design and construction. NTTA did not offer any funding for the project during this support investigation. ZONING· LAND

Page 2 Whitehead Letter September 14,2001 Support for the project is generally good with the related jurisdictions. Coker Company recommends that that Town ofAddison vigorously pursue
additional funding resources from the City ofDallas, NCTCOG, DART and others to fully fund the land acquisitions required, the engineering and ultimately the construction ofthe interchange.

( This report is the result ofan investigation perfonned by the Coker Company on behalf of the Town of Addison to determine the level of potential support from a number of governmental
and quasi-governmental jurisdictions for the construction of a single point urban interchange at the intersection of Beltline Road and the North Dallas Tollway, Dallas, Texas. EXECUTIVE
SUMMARY There is generally support for the project across the jurisdictions and agencies interviewed. There remains some skepticism about potential improvements in mobility and safety
resulting from the operation of this type of interchange. Insuring pedestrian mobility and safety continue to be a theme from a number of the agencies interviewed. Funding, outside of
what the Town ofAddison has identified, has not been committed, but multiple agencies have indicated a willingness to consider funding if appropriate requests are submitted. Other sources
of funds may require significant additional time to acqUire. ASSIGNMENT The Phase I assignment included contacting officials with the specified jurisdictions and determining or assessing
their level of support for the proj ect. Officials in each of the specified jurisdictions were contacted either in person or by telephone. INVESTIGATION TOWN OF ADDISON The Town of Addison,
while not one ofthe jurisdictions to be interviewed, is critical to this assessment of support. Officials and citizens from the town believe that a single point urban interchange (SPUI)
design will improve traffic operations at this intersection. To that end, the citizens have authorized a significant source of funding through the Town's capital bond program to underwrite
a substantial amount of the land acquisition, design and construction for the project. The majority ofthe intersection is within the corporate limits ofthe city of Dallas. Therefore,
obtaining support from the city ofDallas is critical to the potential for success at this intersection. CITY OF DALLAS On June 18, Coker Company representatives Michael Coker and Liz
Carter met with City of Dallas Public Works and Transportation Director David Dybala and one of his Assistant Directors responsible for the Capital Bond Program, Warren Benoy. Mr. Dybala
indicated that he was supportive any intersection design that could improve traffic operations at this intersection. Mr. Benoy indicated that there was money in the upcoming bond election
(May 2002) for improvements to the east of the intersection and
( that he would work to include as much funding as he could for improvements and/or land acquisition at the intersection. Mr. Dybala stated that statistical information that supports
the contention that a SPill will demonstrably improve traffic operations and safety would help him market the concept to the City Manager and the City Council. Coker Company representatives
advised him that that information was available. One concern that Mr. Dybala expressed was related to the pedestrian safety issue. His contention is that there is a significant volume
of pedestrian traffic that crossed over the Dallas North Tollway during lunch hours and in the evening. Coker Company representatives advised him that the Town of Addison is aware of
those concerns and that the engineer/intersection designer is considering all ofthe opportunities available to ensure the safety ofthe pedestrian public. Mr. Dybala and his staff are
supportive of the concept and are interested in cooperating with the design and ultimate construction of the project. COUNTY OF DALLAS Michael R. Coker met with Dallas County Planning
Director, Rick Loessberg and Don Cranford, Assistant Director of Public Works and other senior members of the Department of Public Works regarding the proposed SPUI on July 3, 2001.
Their position was that of moderate support. There was no support for providing additional county funding for the project at this time since their funding cycle recently closed, but
there was no opposition to the concept provided that the SPUI design actually does improve traffic operations and safety. Like the city of Dallas, there was concern expressed regarding
the ability ofpedestrians to successfully and safely navigate their way from one side ofthe interchange to the other. The County supports the project, especially if it improves mobility
and traffic safety. NORTH TEXAS TURNPIKE AUTHORITY On July 3, 2001 Michael R. Coker met with the executive director ofthe North Texas Turnpike Authority, Jerry Hiebert and several senior
staff members. They indicated that they did not have a position about the SPUI concept, but guardedly indicated that an improvement to the transportation system would be a good thing
as long as construction did not adversely affect their main lane operations on the Tollway. Mr. Hiebert and his staffmade it clear that any construction interference with the Tollway's
main lanes would necessarily require significant coordination and cooperation. NTTA staff did not provide any encouragement about funding for any portion of the project.
( ( It is my assessment that NTTA staff are neither supportive nor are they adverse to the concept. They do not want any interchange construction (SPUI or other) to interfere with the
Tollway's ability to move vehicles. DALLAS AREA RAPID TRANSIT AUTHORITY Coker Company representatives, Michael R. Coker and John Abbott met with senior DART manager, Jack Wierzenski
regarding DART's level of support for the concept and whether or not they would be able to contribute any funding to the land acquisition, design or construction of the project. DART
supports any transportation improvement that reduces congestion, improves circulation and vehicular through put, and that does not adversely affect pedestrian mobility or safety. He
indicated that the Town of Addison receives money from DART for them to use for transportation improvements that are important to the overall transportation system and that are consistent
with traffic and safety issues, and that assist in reducing the environmental impacts of vehicular transportation. TEXAS DEPARTMENT OF TRANSPORTATION The Coker Company discussed the
project with staff at the TXDOT regional office. While there was not an expression of support for the project, neither was there opposition to the project. TXDOT supports projects that
improve mobility and that reduce adverse air quality impacts. There was no indication of a willingness to support the project financially. NORTH CENTRAL TEXAS COUNCIL OF GOVERNMENTS
In a telephone conference with Michael Morris at the North Central Texas Council of Governments, it was determined that there is support for the project ifit does improve mobility. It
was also determined that funding for projects of this type can be made available, but the process included an application and review process that can take a long time. Coker Company
recommends that the application process be commenced, especially with as many ofthe potentially affected jurisdictions (including DART) as possible in sponsorship roles. CONCLUSION There
is a consensus of support for the project, especially if this design can improve mobility, reduce operational costs, and not adversely affect pedestrian mobility and safety. There remain
some skeptics regarding the forecasted mobility improvements and projected costs for the design and construction of the project. Additional funding, while potentially available, has
not been committed. The Coker Company recommends that the Town of Addison and the other potentially affected jurisdictions pursue all available avenues of financial support for the project.

Mr. Chutchian: Please find attached out revised proposed scope of services for this study. We have incorporated your comments to the scope and have revised our cost estimate accordingly.
Most of the comments related to the Phase 1 scope were to clarify the meaning of the scope and had little impact on the cost proposal. We did Incorporate additions to the scope for the
design and construction phases but these changes had no impact on the cost proposal as they are to be negotiated when the recommended alternative is selected. The cost proposal includes

( . DRAFT Scope of Services Intersection Improvements Beltline Road at Dallas North Tollway June 18, 2001 The scope of services for Intersection Improvements to Beltline Road at the
Dallas North Tollway includes planning, design and construction phase services. The intent of this scope is to identify and analyze geometric and operational improvements that will make
a significant improvement to the overall traffic operations of the intersection and along Beltline Road. This scope will use previously conducted studies of this intersection as a basis
for alternatives. These previous studies will be the basis for identifying alternatives; however, new traffic information including traffic counts, changes in 􀁉􀁾􀁮􀁤 use, and changes
in travel patterns in the immediate area will be included in the analysis. Stuayalternatives will include five alternatives: the base (existing) condition, also known as the no-build
alternative; one single-point diamond alternative with and one without U-turns; a traditional diamond interchange alternative with geometric and operational improvements, and one additional
alternative. Upon completion of the alternatives analysis phase, the City will select a recommended action for design and construction. Additional right of way may be required at each
of the four corners of the intersection. It may be necessary to relocate City-owned and private or franchise utilities. The City will provide Carter &Burgess all available studies or
plans including plans for cityowned utilities and traffic counts or timing plans for intersections along Beltline Road. Phase 1: Identify and Analyze Alternatives 1.1 Using results from
previous intersection study by Parsons Transportation Group, identify alternatives for intersection improvements. Study alternatives will include five alternatives: the base (existing)
condition, also known as the no-build alternative; one single-point diamond alternative with and one without U-turns; a traditional diamond interchange alternative with geometric and
operational improvements, and one additional alternative. 1.2Collect additional traffic-related information including 24-hour traffic volumes and peakperiod turning movement counts, signal timings, accident data, pedestrian movements, land uses,
etc. Develop design volumes for use in traffic analyses. 1.3 Collect plans of existing facilities in the immediately surrounding area including plans of Beltline Road, plans of the Dallas
North Tollway and Dallas Parkway, utility locator plans, plans of various critical utilities, plats of adjacent developments, etc. 1.4 Supplement plans of existing facilities with field
surveys. Determine locations of property corners for potentially impacted properties. 1.5 With City staff input, develop criteria to evaluate intersection improvements. Standards will
include objective measures such as calculated total intersection delay, lengths of approach queues, additional right-of-way cost, and construction cost. Subjective measures may include
incidental affects to adjacent property, affects to pedestrian movements, ability to effectively sign approaches, etc. 06/21/2001
( 1.6 Analyze alternatives for operational, construction and traffic impacts. 1.7 Meet with affected or involved parties and agencies including DART, Dallas, North Texas Tollway Authority,
County of Dallas, utility companies, adjacent property owners. 1.8 Meet with city staff at various times throughout project. 1.9 Present draft findings including recommended action to
city staff for review and comment. Provide__copies of draft report. 1.10 Incorporate comments on draft findings, update analysis and report and complete final report. Provide __copies
of final report. 1.11 Present final report to City Council in workshop or council meeting format. Phase 2: Design of Selected Alternative The scope of construction for the Beltline Road
intersection assumes (need to identify what we are to design) 2.1 Prepare final construction plans, specifications and estimates of selected alternative. Prepare roadway, drainage, bridge,
retaining walls, and traffic signal, signing and pavement markings designs. Coordinate designs with adjacent private development and with city plans for Beltline Road. Prepare landscape
and aesthetic enhancement plans, sidewalks and pedestrian features, traffic handling for construction, pavement markings, illumination and plans to adjust city-owned utilities. This
scope does not include plans to adjust privately-owned or franchise utilities, or technical assistance in support of condemnation proceedings. 2.2 Obtain additional field information
needed for design including soil boring data and geotechnical recommendations. 2.3 Meet with city staff at least monthly to review progress. As directed by city, coordinate plans with
affected parties. 2.4 Submit to city for review and comment plans at approximately 35-percent level of completion. Plans shall identify significant construction items and include roadway
geometry, location of structures, and overall drainage plan. The cost estimate from Phase 1 shall be updated and confirmed. 2.5 Submit to city for review and comment plans at approximately
65-65-percent level of completion. Plans shall include all roadway and drainage facilities, and traffic control facilities. Structural items shall be significantly detailed. A conceptual
plan to handle traffic during construction shall be submitted. The construction cost estimate shall be updated. A draft outline of construction specifications and bidding documents shall
be submitted. 06/21/2001
2.6 Submit to city for review and comment pre-bid plans. Plans shall be complete and ready for bidding. The construction cost estimate shall be updated and construction specifications
and bidding documents shall be complete. 2.7 City will bid project. Incorporate final plans comments and assist city in bidding project. Attend pre-bid conference. Evaluate bids received
and make recommendation to city of contractor. Phase 3: Construction Phase Services 3.1 Attend pre-construction conference 3.2 Review shop drawings and other contractor submittals. 3.3
Provide engineering design support to city during construction. 06/21/2001
Belt Line Road Intersection Irnprovernents Design Case Scenarios Base condition: re-striping, signal timing adjustments, etc. Nominal design costs. Modifications to standard diamond
interchange configuration: provide additional left-turn lanes, right turn lanes, widen Belt Line Road bridge, revise abutments to accommodate additional bridge beams for widening. Relocate
power transmission line. Complex traffic handling issues. Geotechnical investigations and recommendations. SPUI alternatives: widen Belt Line Road bridge, modify existing bridge construction,
posttensioned cantilevered frontage roads over DNT, drilled shaft designs for widening bridge abutments and for cantilevered frontage road, coordination with NITA for construction impacts

Noah: As you may know, the Town of Addison is continually seeking ways to improve the flow of traffic through the Town. Our busiest east-west thoroughfare is Belt Line Road, which carried
67,000 vehicles per day at our last count a little over one year ago. Accordingly, we are proposing to convert the Belt Line/Dallas Parkway intersection into a Single Point Urban Interchange
to improve the efficiency of the intersection in all directions. I have enclosed one copy of a Design Report prepared by Barton Aschman Associates, Inc. (October, 1995), that gives the
results of a study to identify and evaluate alternatives for improving traffic conditions at the Belt Line/Dallas Parkway intersection. I have also enclosed one set of plans that show
the concept we propose. The plans include a plan view that shows an expansion of the bridge deck to accommodate the left turn lanes, a drawing showing the drilled shaft and cantilever
bent concept of support for the expanded deck, and a drawing showing the resulting clearances between the cantilever bent and the outside curb lane. Counts of pedestrian crossings are
recorded on the plan view for one mid-week day in September, 1997. We have submitted the plans to Mr. Jack Antebi, P.E. of the Dallas Public Works & Transportation Department and have
received favorable comment. An updated concept project cost estimate is also enclosed. Since this project will benefit both DART and the City of Dallas, as well as the Town of Addison,
the Town would like to propose proceeding with the project under. a cost sharing program, with 1/3 of the funding each coming from the Town of Addison, DART and the City of Dallas. Funding
would include final engineering, right-of-way acquisition, and construction costs. The Town would be willing to manage the project and absorb the management costs.

propose. The plans include a plan view that shows an expansion of the bridge deck to accommodate the left turn lanes, a drawing showing the drilled shaft and cantilever bent concept
of support for the expanded deck, and a drawing showing the resulting clearances between the cantilever bent and the outside curb lane. Counts of pedestrian crossings are recorded on
the plan view for one mid-week day in September, 1997. A concept cost estimate is also enclosed. Please perform a "technical" review of this submittal so that we may have the benefit
of your comments. After you have had time for your review, we would like to meet with you to receive your comments. In the meantime, if you have any questions, please call me'at 972-450-2879.

( PUBLIC WORKS DEPARTMENT May 8,1997 .MEMORANDUM TO: Ron Whitehead, City Manager FROM: John Baumgartner, Director ofPublic Works-pCJJ k 􀀮􀀺􀁲􀁋􀁾 SUBJECT: Engineering Services Contract
with Barton-Aschman (972) 450-2871 16801 Westgrove Attached is a proposal from Barton Aschman Associates, Inc. to provide engineering and surveying services for the schematic designs
of a Single Point Urban Interchange and pedestrian bridges at the intersection of Belt Line Road and Dallas Parkway. The proposal is in the amount of $50,247.95. The project is a budgeted
item. The proposed Single Point Urban Interchange will allow the intersection to operate like a normal four approach intersection. (i.e. Midway/Belt Line) This will reduce the length
of the traffic signal cycle and will increase the capacity of the intersection approximately twenty-five percent. The proposed improvements will require the widening of the existing
bridge, which is owned by the Texas Turnpike Authority and controlled by the city of Dallas. The new new configuration of the intersection will also make it difficult for pedestrian
traffic to safely cross the intersection. Pedestrian bridges across the tollroad will be investigated as part of this contract. The scope of the project will be the preparation of schematic
designs, cost estimates, preliminary environmental assessment, and potential sources of construction funding. This information will allow the Town to decide whether or not to proceed
with this project. If the Council elects to proceed with the project, staffwill enter into discussions with the TTA, DART, and the city of Dallas. Staff requests that the Council approve
the proposal from Barton-Aschman Associates and authorize the City Manager to execute the agreement in the amount of$50, 247.95.

a Letter of Agreement between the Town of Addison (Client) and Barton-Aschman Associates, Inc. (BA) to provide the scope of services described below. PROJECT UNDERSTANDING Barton-Aschman
has previously prepared traffic studies and analyses using an SPill as an alternative. The analyses indicated that the SPUI would be an effective and appropriate traffic enhancement
at this intersection. The purpose of this project is to prepare a schematic design, estimate costs, provide environmental assessment documentation, and identify potential sources of
construction funding. SCOPE OF SERVICES The attachment includes the services to be provided for this project. SCHEDULE We estimate that we can complete this project within four (4) months
(exclusive of review time) following receipt of a signed copy of this Letter of Agreement. We are prepared to begin work on this project immediately. MEETINGS For the purpose of our
fee estimate, we have included the cost of attending five (5) meetings with the Town of Addison. This cost for BA to attend additional meetings, if authorized, will be billed separately
on a cost and expense basis.
FEE FOR SERVICES AND METHOD OF PAYMENT The fee for completing the project will be on a Lump Sum basis for services rendered. We estimate the cost to perform the scope of services, outlined
in the scope of services, is $50,247.95. This fee will not be exceeded without authorization from the Client. Direct reimbursement for out-of-pocket expenses such as mileage, reproduction,
etc. will be billed at cost and is included in the quoted fee for this project. The fee for extra meetings, work sessions, and presentations (and work in addition to the tasks indicated
in the Scope of Services) will be billed separately based on our hourly rates for staff time and expense. Invoices will be submitted monthly and will indicate charges incurred during
the preceding month. Billings are due and payable within thirty (30) days of invoice date. A one and one-half (1.5) percent carrying charge will be added each month to all past due accounts.
AUTHORIZATION We are prepared to initiate work on this project immediately upon receipt of a signed copy ofthis Letter of Agreement. This proposal will remain valid for thirty (30) days.
We appreciate the opportunity to submit this proposal and look forward to assisting you on this project. Uyou have any questions regarding this proposal, please do not hesitate to call.

study of potential traffic flow improvements at Belt Line Road and Dallas Parkway. I have attached HNTB's review comments for your consideration. The TTA will be supportive of the improvements
proposed by Barton Aschman, provided they do not adversely affect traffic flow on the Tollway. Northbound P.M. traffic flow on the Tollway at Belt Line is so heavy that the TTA cannot
tolerate any structural modifications that would produce Tollway operational flow problems in that location. w· mes . Griffin, P.E. ecutive Director ek Ene. cc: HNTB Engineering MEMBERS:

TOLLWAY DNT-240 General Consulting Services Belt Line Road Traffic Revisions Dear Mr. Griffin: !·iil·iO.• !l.•.. We have reviewed the Design Report prepared by Barton Aschman for improvement
of the efficiency of traffic flow at the intersection of Belt Line Road and the Dallas Parkway. Three alternatives are presented in the report with each having an affect on the Texas
Turnpike Authority (TTA) facilities. Alternative 1 has the least effect on the TTA's, facilities and apparently would only require modification of the island separating V-turn traffic
from the through traffic on Belt Line Road. As noted in the report, though, this alternative does little to improve traffic efficiency. Alternatives 2 and 3 are essentially the same
insofar as the effect on the tollway bridge structure at Belt Line Road. The right-of-way needs for Alternative 3 appear to be somewhat greater than for Alternative 2, but since the
additional property is to the right of the frontage road, that issue should not affect the Authority. The Single Point Vrban Interchange introduces significantly larger turning radii
on the left turn lanes through the intersection. Due to the close proximity of the left turn lanes to the retaining wall and bridge structure and the larger radii, the resulting left-turn
roadway will overhang the wall and require a radius corner extension at each corner of the bridge. Radius corners already exist on the bridge, and it would not be practical to introduce
a bridge slab projection or cantilever in excess of that currently constructed on this prestressed concrete beam structure. It may be possible to remove a portion of the existing bridge
under the V-turn lane and reconstruct this portion of the bridge to accommodate the radius corner utilizing a post-tensioned concrete box structure with a center median support pier.

( Texas Turnpike Authority Dallas, Texas 75.219 -2-( Dallas North Tollway June 17, 1996 Bridge modification would require cast":in-place construction over the Tollway and would restrict
clearance to about 12 feet. Retaining walls at each comer of the bridge would require modification, and traffic on lanes adjacent to the median would need to be controlled during construction
of the median support. These construction operations would create significant congestion for the tollway traffic. With respect to the cost estimate, we note the unit price for bridge
modification is probably too low for the relatively small area of structure and difficulty of construction in the severely restricted area. Please call and we will be pleased to discuss
the proposed plan in more detail if you wish. Very truly yours, HNTB CORPORATION 􀁾(􀁚//;'􀂣􀁃i ..􀁾-􀁽􀀬.􀁾􀀻􀀢.􀀯"􀀭􀀦􀁾􀁾􀁾􀀮.􀁾􀀮 Daniel F. Becker, P.E. Vice President, Central Division

Baumgartner, Director of Public Worky , Dallas North Tollway at Belt Line Rd. Attached is a proposal from Barton-Aschman to provide professional engineering services to study the possible
alternatives to reconfigure the Belt Line Road/Dallas Parkway intersection to obtain additional capacity. This intersection is located in both the Town ofAddison and the City ofDallas
and currently operates at a "level of service E or F". Barton-Aschman's proposal will examine the possibility of separating to north and south bound movement while still providing for
multiple turning movements at Belt Line; at grade improvements, and the use of a modern urban interchange. The fee proposed for this initial phase ofthe project is a time and materials
fee not to exceed $19,700. Because this study was not budgeted, funding will come from an unencumbered portion ofthe existing general fund balance. Staffrecommends the council consider
the proposal and authorize the City Manager to execute the Agreement with Barton-Aschman for a time and materials fee not to exceed $19,700. JRB/amh Attachments 1. Barton-Aschman Proposal

at Belt Line Road Study Dear Mr. Baumgartner: Barton-Aschman Associates, Inc. is pleased to submit this proposal to provide professional transportation planning and engineering services
in connection with the proposed access roadway associated with the Dallas North Tollway at Belt Line Road Study in Addison, Texas. Based on our discussions and understanding of the project,
we have prepared a Scope of Services for this project. Our study approach and Scope of Services are presented below in this proposal. If accepted, this letter will become an agreement
between Town of Addison and Barton-Aschman Associates, Inc. to provide the services described in the Scope of Services below. SCOPE OF SERVICES Our Scope of Services includes the following
work tasks. Task 1.0 PROJECT INITIATION MEETING We will meet with the Town of Addison (Town) staff to discuss the proposed scope of services, project schedule, data collection activities,
unit cost information, evaluation criteria, and simulation procedures and outputs. We will also discuss possible roadway improvement alternatives to be a analyzed in subsequent tasks.
Output: 1. Finalized Scope of Services and Schedule. 2. Evaluation criteria for analysis. 3. Alternatives to be evaluated. 4. One meeting with Town staff. riil 􀁾 PARSONS
( Mr. Baumgartner January 18, 1995 Page 2 Task 2.0 DATA COLLECTION We will collect the following data to form a sound basis for subsequent analysis: • P.M. Peak Hour turning movement
counts. These counts will be conducted on a Friday between the hours of 4:00 P.M. and 6:30 P.M. • "As Built" plans for the study intersection. • Existing utility information. • Existing
Right-of-Way information. • Toll Plaza discharge rates for entering and exiting toll booths south of Belt Line Road. • Existing Signal Timing plans for the Belt Line RoadJDallas North
Tollway Intersection. • Existing lane configurations. • Saturation Flow Rates for all approach movements to the intersection. • Vehicle delay studies for each approach to the intersection.
• Site plans for adjacent properties. • Design plans for proposed right tum lane for eastbound Belt Line Road traffic. Output: 1. Database of existing transportation infrastructure and
traffic characteristics for the study intersection. TASK 3.0 SIMULATE EXISTING CONDITIONS We will conduct an analysis of existing conditions during the P.M. peak hour at the intersection
using the TRAF-NETSIM microscopic traffic simulation model. The model will be calibrated to existing conditions observed in the field. Model outputs include vehicle delays and stops,
number of failed cycles during the design period, and vehicle emission information. These existing measures of effectiveness (MOEs) as the base conditions in the utility/cost analysis
of each of the alternatives.
Mr. Baumgartner January 18, 1995 Page 3 Output: 1. Calibrated simulation model. 2. Existing conditions MOEs. TASK 4.0 PREPARE BASE MAPS We will prepare base maps for the study intersection
using the data collected in Task 2.0 Base maps will be prepared in AUTOCADD (vI2.0) at a scale of 1"=50' on 24"x36" sheets. The base maps will include existing roadway curb lines, R.O.W.
information, lane configurations, utilities (including drainage), and prominent features (i.e. parking lots, building footprints, etc.) on adjacent properties. Output: 1. Base maps of
existing conditions. TASK 5.0 DEVELOP INTERSECTION IMPROVEMENT ALTERNATIVES We will develop three intersections improvement alternatives for further analysis. Up to five conceptual alternative
sketches will be developed for Town of Addison review based on discussions with Town staff included in Task 1.0. The three alternatives selected for further development and analysis
will be chosen during a work session with Town staff. It id anticipated that the three alternatives will include the following: • At-grade improvements only. • Depression of the Northbound
and Southbound Dallas North Tollway Frontage Roads. • Modern urban interchange. The three alternatives will be developed on the existing base maps using AUTOCADD. The alternatives will
be submitted to Town staff for review and comments and finalized during a work session with staff. Output: 1. Three improvement alternatives for analysis. 2. Two work sessions with Town
staff.
( Mr. Baumgartner January 18, 1995 Page 4 TASK 6.0 PREPARE ENGINEER'S OPINION OF COST We will prepare an engineer's opinion of cost for each of the three alternatives developed in Task
5.0. Output: 1. Spreadsheet showing the engineer's opinion of cost for each alternative. TASK 7.0 SIMULATE EACH ALTERNATIVE We will simulate traffic conditions for each of the three
alternatives using the calibrated simulation model developed on Task 3.0. Measures of Effectiveness for each alternative will be the output of each of the simulation. We will also video
tape the simulation graphics developed by the TRAP NETSIM model for each of the alternatives. Output: 1. MOEs for each of the alternatives. 2. Video tape of simulation graphics for each
alternative. TASK 8.0 CONDUCT UTILITY/COST ANALYSIS We will conduct a utility/cost analysis of each of the alternatives using the evaluation (utility) criteria identified in Task 1.0
and the MOEs from the simulation tasks. This utility/cost analysis will identify the preferred alternative based on the criteria and need identified in previous tasks. The results of
the utilitylcost analysis will be submitted to Town staff for review and finalized in a work session with staff. Output: 1. Utility/cost analysis of each alternative. 2. Preferred alternative.
3. One work session with the Town staff. TASK 9.0 PRESENT TO TOWN COUNCIL We will present the study procedures, findings, and conclusions to the Town Council for their review and comment.
Output: 1. Five copies of draft report. 2. Ten copies of final report.
Mr. Baumgartner January 18, 1995 Page 5 TASK 11.0 MEETINGS For purposes of our fee estimate, we have assumed our attendance at two meetings in addition to the meeting and work sessions
identified in the previous tasks. We are certainly available to attend any meetings deemed necessary. However, additional meetings will be beyond the scope of this study and will be
considered additional services. Additional meetings will be billed separately based on time and expenses incurred. Output: 1. Two meetings with Town staff. FEE FOR SERVICES AND METHOD
OF PAYMENT The fee for completing the project will be based on our hourly rates for staff personnel, current at the time of performance for staff services rendered. The maximum fee and
expenses for completion of this project will not exceed $19,700 without receiving written authorization. Direct reimbursement for reasonable out-of-pocket expenses such as mileage, reproduction,
etc., will be belled at cost and will be added to the staff time costs incurred on the project. Invoices will be submitted monthly and will indicate charges incurred during the preceding
month. Billings are due and payable within thirty (30) days of invoice date. A one and one-half (1.5) percent carrying charge will be added each month to all past due accounts.
( Mr. Baumgartner January 18, 1995 Page 6 AUTHORIZATION We are prepared to initiate work on this project immediately upon receipt of a signed copy of the Letter of Agreement. This proposal
will remain valid for thirty days. We appreciate the opportunity to submit this proposal and look forward to assisting you on this project. If you have any questions regarding this proposal,
