RE: Additional Service Amendment #1, P.O. #27438
Dear Haseeb:
As we discussed, the City of Carmel has a need for additional professional services and pursuant to our current
contract with DLZ, Contract #050510.15 dated May 5, 2010, I have requested and received from you the proposed
scope of services and fee estimates for the following work task:
Additional Service Amendment #1— 126`" Auman Drive Intersection Study
Traffic Control Study
See "Attachment A" Not to Exceed: $13,500.00
Per our contract procedural requirements, I hereby approve these Additional Professional Services estimates, and
request that the Board of Public Works ratify the above referenced Contract Amendment.
PLEASE NOTE
Please be advised that "Additional Services" performed on City contracts must be billed separately from the original
contract and other additional services. More importantly, the invoice must reference the appropriate Additional

Re: Professional Engineering Services Proposal
126 Street and Auman Road Intersection Study
Dear Mr. McBride:
DLZ Indiana, LLC (DLZ), appreciates the opportunity to provide the City of Carmel (City) with this
proposal for the study of 126 Street and Auman Drive intersection. The following project
understanding and subsequent scope is based on our meeting discussion dated June 16, 2010.
DESCRIPTION OF THE STUDY
This Study will evaluate possible conversion of the 126 Street and Auman Drive intersection to a
One -Way stop condition on Auman Drive. The intersection is currently controlled by an All -Way
stop condition. The City has indicated the desire to convert this intersection to a 1 -way stop since
the previously restricted intersection sight distance (ISD) has been mitigated by the City and there are
no ISD issues at the present. Furthermore, the City would also like to evaluate the traffic conditions
under the following control types:
1. One -Way Stop
2. All -way Stop
3. Traffic Signal
4. Roundabout
All of the afore mentioned control types will be evaluated based on the existing available traffic data
from the City. DLZ may also utilize available traffic information from the previously conducted
traffic study done by DLZ dated December, 2009 (Carmel Traffic Study). Both the City and DLZ
understand that the existing traffic patterns, due to the on -going construction on the Keystone
Avenue, will nullify any additional data collection at this time due to road closures, detours, etc.
Therefore, collection of additional traffic is not practicable for the purposes of this study.

126` Street and Auman Road Intersection Study

SCOPE OF WORK
DLZ's scope of work will include the following:
1. Task 1 Traffic Data Coordination:
DLZ will coordinate with the City to gather the existing traffic data for the subject intersection
and /or the Average Annual Daily Traffic Volumes (AADT) for the adjacent roadways. All traffic
data will be provided by the City for the purpose of using in this study. It is assumed that the
intersection turning movement counts (TMC) are not available. The TMC will be derived using
the following assumptions, as suggested by the City:
Eastbound and westbound 95% thru 5% left turns (both AM PM peaks hours)
Northbound 30% left turn and 70% right turn (AM peak hour); 50% each left and right
turns (PM peak hour)
The above peak hour TMC will be derived utilizing the AADT for 126 Street and Auman
Drive, as provided by the City. As per the estimates stated in the Carmel Traffic Study, DLZ will
assume a 50/50 directional split of AADT on the roadways and the AM and PM peak hour
volumes as 9% and 11% of the AADT, respectively.
The available traffic data will be projected to reflect the year 2010 traffic volumes utilizing the
traffic growth rates identified by the City, which are 2% and 0.5% annually for 126 Street and
Auman Drive, respectively.
2. Task 2 Traffic Signal and All -Way Stop Warrant
Utilizing the traffic data in the Task 1 above, DLZ will estimate the intersection TMC for the
warrant analysis purposes. These estimates will be done for both a traffic signal as well as for
checking the criteria for an All -Way stop condition. These warrants /criteria will be in
accordance with 2008 Indiana Manual on Uniform Traffic Control Devices (MUTCD). Since the
continuous 8 -hour intersection TMC are not available, DLZ will assume that the 8 highest hour
volume is 65% of the peak hour volume for these warrant analyses purposes.
If the assumed data indicate the traffic signal warrant may be met, DLZ will prepare a conceptual
layout of a traffic signal at the subject intersection along with a preliminary opinion on the
probable construction cost. It is assumed that a detailed /itemized cost statement will not be
required at this stage.
3. Task 3 Roundabout Analysis
DLZ will evaluate the option of a roundabout at the subject intersection. Rodel software will be
utilized to perfor n the capacity analysis for existing traffic conditions and to determine the
roundabout lane requirements. A conceptual layout will also be prepared for the roundabout
option for comparison purposes only along with a preliminary opinion on the probable
construction cost. The construction cost will be based on the overall area (in square feet) of the
J

potential roundabout pavement. A cost per square foot will be determined by DLZ based on the
past roundabout experience. It is assumed that a detailed /itemized cost statement will not be
required at this stage.
4. Task 4 Intersection Sight Distance
DLZ will conduct a field visit to verify that the existing intersection sight distance (ISD)
conforms to the current standards as set forth in the Indian Design Manual. This task will be
based on the preliminary field observation only and no detailed analysis or field survey will be
performed.
5. Task 5 Traffic Animation
DLZ will utilize Synchro /Sin7Tralic (version 7) traffic model to simulate the traffic conditions
along the 126' Street corridor between Rangeline Road and Keystone Avenue. The purpose of
this task is to demonstrate the gaps available in the 126 Street traffic stream for Auman Drive
motorists under a One -Way stop condition at the subject intersection. This model will extend
from the intersection of 126` Street /Rangeline Road to immediately before 126 Street /Keystone
Avenue roundabout interchange (this roundabout interchange will not be modeled).
6. Task 6 Crash Data Review
DLZ will review the most recent 3 years of crash records for the 126` Street and Auman Drive
intersection. This review will be performed to review any consistent crash frequency that may be
attributable to the existing stop control. The City will provide the crash data for DLZ's review
and DLZ will also prepare a crash data summary for the subject intersection.
7. Task 7 Report
Upon completion of the preceding tasks, DLZ will provide a letter report to the City stating the
finding and recommendations. Based on the assumptions for deriving intersection TMC and
warrant analyses stated above, DLZ may recommend a need for traffic volume verification once
the Keystone Avenue construction project is completed and normal traffic patterns are restored.
8. Task 8 Meetings:
DLZ will attend one (1) meeting with the City or the City Council members to present the
findings of the study and also to present the traffic animation (as per the Task 5 above).
ADDITIONAL SERVICES
Additional services that are not included in this fee proposal but can be provided include:
1. Traffic data collection.
2. Analysis of future traffic conditions.
3. Detailed design services
4. Topographic Survey
