Proposed Scope of Work October 22. 1991
FIVE -CITY TRAFFIC STUDY
The following is a proposed scope of work for completing the Five -City traffic study. It
addresses the revisions to the original scope of work as discussed at the September 8th meeting*of
the City Managers, and the directions given at the meeting with technical staff on October 8th.
OVERVIEW
The work carried out to date for the Five -City traffic study has included the development of
a traffic modeling capability (short-range and long-range), preparation of land use data, short-range
(1995) traffic forecasts, and identification of potential traffic improvements at selected intersection
locations in each of the five cities. A comprehensive interim report is available which documents the
results of this work.
The revised scope of work will continue to focus on the short-range, but will use a seven-year
time frame (1999) rather than the 1995 data that is currently the basis for the short-range analysis.
The land use data will be revised accordingly, and new traffic forecasts produced. These revised
forecasts will be used to update the short-range traffic improvements. Cost estimates will be
produced for the improvements and a nexus analysis carried out to allocate costs to the seven-year
land use forecasts.
The long-range analysis will produce ADT and peak hour traffic forecast data and examine
the short-range improvements within a longer range context. The intent is to ensure that the short-
range improvements appear warranted in the long-range, and are consistent with current long-range
improvement plans and/or General Plan Circulation Elements.
The product of the study will be a seven-year transportation improvement program and
corresponding nexus findings. Improvements will be specified in terms of intersection lane
requirements, and the nexus information will equate improvement costs to land use growth in each
part of the analysis area.

WORT{ ITEMS
The work items that are proposed here can be summarized as follows:
I. Revised Short -Ran a Anal sis
The interim report produced for the Five -City Traffic Analysis contains considerable
information with respect to short-range improvement needs. Questions regarding feasibility of some
of the projects will be resolved, and the program will be updated to reflect the seven-year time frame.
The steps that will be undertaken in this regard are as follows:
1. Prepare new land use database (1999;
2. Prepare new traffic forecasts
3. Revise improvement program
It is anticipated that item 3 will involve numerous iterations with respect to traffic model data,
and will require considerable input from the project team. The product will be a revised version of
the short-range improvement program.
2. ImRroyement Costs
In this work item, costs will be assembled for the improvements identified in work item i
above. These cost estimates will be prepared by each jurisdiction, and reviewed by AFA for
reasonableness.
3. Nexus Analysis
This step in.. the analysis will be a r exus evaluation of the improvement costs and land use
growth in the study area. The nexus procedure will relate the costs of the improvements at each
individual location to the growth in land use (existing to 1999). The result will be a set of costs per
tripend specified by individual areas within the overall study area.
In carrying out this analysis, a set of sub -areas will first be defined, and the growth in land
use in each sub -area will be estimated. Various nexus formulations will then be analyzed, taking into
consideration participating development, existing fee programs, etc. While at this stage it is not
intended that the nexus results should be directly converted into a fee program, the results will
Four -City Traffic Study 2 Austin -Foust Associates, Inc.
provide some general cost parameters for evaluating potential funding mechanisms.
4. Post-2010 Tralrc Forecasts
The traffic model used in the Five -City study has a Post-2010 version that can be prepared
for use without a major work effort. This model will be used for identifying peak hour intersection
volumes in a similar manner to that carried out for 1999. The peak hour forecast data will be utilized
to prepare intersection capacity utilization (ICU) values for this long-range time period. A
preliminary set of lane configurations will be prepared for each intersection to show the type of
improvements that may be needed: These configurations will be preliminary in nature, and will not
be subject to a detailed feasibility and cost analysis.
5, Final Report and Presentations
The results of the traffic analysis will, be written into a final report, and up to five
presentations will be given to summarize the findings.
COST ESTIMATE
The traffic model area includes the City of Tustin, although the short-range version of the
model will need to be set up to process intersections in Tustin. Assuming availability of traffic count
and land use data, this is estimated to cost around $3,000. The additional cost for carrying out the
above five work items with an expanded study area that includes intersections in Tustin is $6,000.
Table 1 summarizes the estimated costs for the scope of work described here. It includes the
City of Tustin as a participant in this next phase of the study. Additional costs for each city can be
summarized 'as follows:
Total work effort cost $49,000
Less funds remaining $25,000
Net Additional Cost $24,000
Cost per City:
Tustin $9,000
Others $3,750

Direct the City Attorney to prepare and authorize the Mayor and
Clerk of the Council to execute an amendment to the agreement with
Austin -Foust Associates, Inc. for the Five -City Traffic Study for
additional professional services in the amount of $3,750.
The Five -City Traffic Study is a cooperative effort between the
cities of Tustin, Costa Mesa, Irvine, Newport Beach and Santa Ana.
The area under study encompasses major employment centers in the
South Coast Metro Business Area of Orange County. The purpose of
the original study was to identify needed short-range
transportation improvements generated by development within the
study area and to provide a funding mechanism to implement the
improvements.
In June 1989, the Inter -City Liaison Committee retained the
services of Austin -Foust Associates, Inc. to conduct the traffic
analysis. On March 19, 1990, the City Council authorized the City
to join in the cooperative study, and Santa Ana's participation
required a contribution not to exceed $15,000. Austin -Foust
Associates, Inc. has completed all of the tasks identified in the
original scope of work. The work completed to date has included
development of traffic modeling capability , preparation of land
use data, traffic forecasts through 1995, and identification of
potential traffic improvements at selected intersection locations
in each of the five cities.

AMENDMENT TO AGREEMENT FOR
FIVE -CITY TRAFFIC STUDY
June 1, 1992
Page 2
Staff from each of the cities has agreed that the scope of work
needs to be revised. The revised scope of work will continue to
focus on short-range time frames, but will use a seven-year period
through 1999. The seven-year time frame was agreed to because it
is more compatible with transportation planning for Congestion
Management and Measure M Program purpose.
The land use data will be revised accordingly and new traffic
forecasts will be produced. The revised forecasts will be used to
update the short-range traffic improvements. Cost estimates will
be produced for the improvements and a nexus analysis will be
conducted to allocate costs to the various jurisdictions. The
study will include a seven-year transportation improvement program
and corresponding nexus findings. Improvements needed will be
specified in terms of needed traffic system improvements. The
additional cost to the City of Santa Ana is $3,750 to complete the
work effort described above.
FISCAL IMPACT
Funds for the City of Santa Ana's share of this work effort are
budgeted and available in the Five City Traffic Study Project
(account no. 42-631-6631).
