Council Meeting, April 12, 1.988 Santa Monica, California
..-
To: Hayor & City Counci1.
From: city Staff
Subject: Recommendation to Authorize the City Manager to
Negotiate and Execute a Contract with Crain &
Associates to Conduct a Citywide Traffic Study.
Introduction
This report requests that the City Council authorize the city
Manager to negotiate and execute a contract with Crain &
Associates to conduct a Citywide Traffic Study.
Executive summary
The proposed Citywide Traffic study has several key purposes.
These are to:
1. Evaluate existing and future traffic conditions for the
-
city's street system and identify problem areas. Future
conditions will include evaluations under several scenarios
on levels of development.
2. Develop and prioritize traffic mitigation measures for
existing and future traffic problem locations. These may
include physical improvements to streets, as well as both
transportation systems and transportation demand management
techniques (TSMjTDM) .
b....L
- 1. - APR 1 2 1988
3. Develop financing plans and programs for the proposed
traffic mitigation measures. These may include traffic
mitigation fees, assessment districts, or other methods.
I 4. Develop neighborhood traffic mitigation plans and programs
to address concerns about traffic intrusion, etc. These will
be tailored to individual neighborhoods, most impacted by
these prOblems, but may be similar in nature.
5. In light of the information developed by the study, review
the City's development standards and identify possible
changes to those standards.
The length of the study is approximately eight months and will
include extensive public participation. Some of the
recommendations for traffic mitigation of existing conditions and
neighborhood traffic control may be implemented during the study
period and need not be delayed to the end of the study. The
budget for the study is approximately $210,000.00.
Baekground
One of the City's current year budget objectives is to coordinate
the preparation of a citywide traffic study. The City Council
provided funds to conduct this citywide traffic study in the
Fiscal Year 87-88 budget. The purpose of the proposed study is to
analyze traffic issues throughout the city and develop a program
to address existing and potential problem areas. A key goal is to
prepare a comprehensive traffic improvement program that would
provide the city with a clear direction in which to proceed.

Staff therefore believes the study will be an important element
in planning for the City's future. It should be noted that the
city has never before conducted such an extensive study of
traffic in Santa Monica.
In the fall of 1987, staff received various proposals to conduct
the study. Three consultant teams were interviewed. Although each
consultant team appeared technically qualified, staff did not
feel that any of the t.hree proposals fulfilled all of the
requirements. It was decided an alternate method of selection was
necessary.
In early 1988, st.aff asked an additional team, Crain <<
Associates, to submit a proposal. Staff approached Crain <<
Associates because they are well qualified and recently displayed
exceptional ability in working wi th neighborhood groups. In an
interview, staff determined Crain & Associates was a good
candidate and unanimously agreed to recommend that the City
proceed with them.
+.
A su~mary of the work program and a project schedule are enclosed
as Exhibits 1 & 2. The project will include extensive public
participation. Each major work product will be made available for
public review. The project budget also includes six public
workshops, a total of four public hearings before the Planning
Commission and City council, citywide telephone surveys of
residents and employees, and up to thirty small-group meetings
regarding neiqhborhood traffic improvements.
- 3 -
An important component of the proj ect will be an evaluation of
the city's development standards in the context of the traffic
projections developed by the study. This evaluation will result
in an information base which can potentially serve as the
foundation for decisions which will shape the future traffic
environment of the City.
Although the project length is approximately eight months, staff
believes some traffic mitigation measures can be implemented
during the study period. For example, once existing problem areas
are identified and mitigation measures proposed, some of the
measures, such as signal timing, signing, striping, etc. can be
implemented. Also, the same may apply to neighborhood traffic
control measures.
BUdget/Financial Impact
The cost of the study is approximately $210,000.00 and will be
funded from account nmnher 01-770-415-000-903 which was budgeted
in the FY 87-88 Capital Improvement program for this purpose.

SUMMARY OF SCOPE
r- Overview
I
i
,
1 The work program set forth emphasizes the process we feel will result In the best
I
i end products; the Near- and Long-Term Transportation Improvements. as well as
r
1
FinanCJal and Land Use Control Plans. Tasks wlthm the study are viewed as
components of the final products. The Intermediate tasks and reports will be
f' designed to produce useful information In their own- right and will be tailored to
provIde the necessary input into the subsequent tasks 10 a useful format. likewise,
! we have allowed for a high degree of interaction among those tasks which WIll be
I conducted concurrently. This interaction w1l1 be especially important dunng the
initial data gathering (Tasks 1. 2 and 3) to avoid duplication of effort. and during
[ the design of the Near- and Long-Term Transportation Improvement Plans (Tasks 7
[ and 9) to ensure that all elements of the plan represent comparable levels of effort.
Finally. this study effort will also interlace with other recent and ongomg studies,
I induding the City-Wide T5M Plan and the updating of the City's Land Use and
I . Circulation Element.
...-
L Data Base Con:atnJction
f_ During Task 1. massive amounts of traffic and highway systems data will be
gathered. City records will provide the pnmary data source. An Integrated
I approach wiJI be used whereby all information needs and the probable source
1 records will be identified, followed by a supplemental information search. ThiS Wtlt
again eliminate duplication of effort and allow all informatIon to be gathered In a
r timely fashion.
L
1--
I
I 7
The second source at data to be utllized dUring Task 1 will be current aenal
I J photographs. Use of aerial photos Will provIde a cost~ffectJve method tor
... r' analyzIng areas and determining data not contained in Gty records. The aenai
: photos WIll also be used for land use data to be collected In Tasks 2 and 3.
r
The third data source will be field surveys. Because this is the most expensive and
tJme.<onsummg data gathering method, its use will be minimized. However, some
,
data, such as pavement conditJon. parkmg conditions. etc., 15 best determined
r" through fieid surveys. AdditIonally, selected field checks WIU need to be conducted
i
I
[ to venfy much of the data gathered by other methods.
1 During Tasks 2 and 3, land use data Will be collected in much the same manner as
roadway information will be collected dunng Task 1. First, City. County. SCAG and
[ census records will be coHected, then aerial photos, and finaHy field surveys Will be
L utilized. Task 2 will conceflU'cste on producing data sets and models for use
throughout the study. Appropriate updates of the data sets will be made, With Task
I 3 bemg used to make the most concentrated land use changes -those in the City of
l . Santa Monica. Data collected In Task 1 Will be used to update the highway network
'-~
withm Santa Monica.
,-
I, Analysis
t Task 4 Will be used to identify eXIsting problems withm Santa MOnica, the attitudes
t
; of resIdents and employees toward those problems, and potential solutions.
L
I VolumeJcapacrty analysis will be used to Identify eXlstmg roadway deficiencies.
I General descriptions of the improvements necessary to provide acceptable levels of
L service will be produced. Also, as part of Task 4, surveys will be conducted to
t determme the attltudes of residents and employees concernmg problems and
I
~
8
potentIal solutJons (e~g. resldentJal preferential parking permit programs and
employee ndeshanng programs).
The aim ot Task 5 1$ to establish a near.term base case under the assumption that
,
the current status quo is maintamed. EstImates of the likely levels of de'lelopment
wtll first be produced. Indhndual prOJects WIn be identIfied and traffkwill be
assigned to the network using the Impact analysiS method. Volume/capaClty
analYSIS will be employed using the projected volumes and the scheduled roadway
;:- system improvements.
l The computer model of existing conditions will be run and calibrated during task 6.
I
L As a starting point. regionally calibrated values will be used in the model. Since the
l software package which WIIJ be used (MINUT?) is a micro-<omputer version of the
[ most commonly used main-frame model, this set of parameter values should
produce good Initial results. The parameters will be further calibrated until the
F model replicates existing conditJons in Santa Monica. Also during this Task, the
1
near-term conditions Wilt be modeled to validate both the calibration and the
,
i impact analysis ~s51.Jmptions.
I ....
Plan Development
I
L During Task 7, the Near.Term Transportation Improvement Plan will be developed.
'"
1 This plan will contain three separate elements - capaaty increases (TSM measures,
1 signal Improvements and capital improvements). demand reductions (TOM and
tranSit programs) and residential neighborhood intrusion reductions. Design of the
1 three elements will occur slmultaneously_ We will defer conducting
I volume/capacrty assessments and computer runs until after a preliminary set of
I improvements IS established for each element. The analysis tools will then be used
r in an iteratlve fashion, as a tool to help produce a more balanced overall plan. A
r
-
9
sens'tlVlty analysIs wIll be conducted to aid In thiS effort.. The key to establishing a
cost~ffectJve overaH plan will be to maXImize the interaction between its three
~ I
r elements. Cost effectiveness of the total package will be the mam cntenon In
I
[ determming what mix of these three elements is Incorporated into the final plan,
I
,
but other conSiderations, such as public acceptability and environmental Impact,
will also be used. LastJy, a finanCIng plan WtlJ be developed to provide the necessary
{ level of funding 10 order to meet the recommended Implementation sched ules.
The long-term scenanos will be developed during Task 8. First a buiJdout scenano
f WIll reflect development of vacant parcels and redevelopment of other parcels to
I their General ptan intensity for a specific target year determined by City staff. The
I level of redevelopment will be based on historic rates. An additlonaJ product of
Task 8 will be an estimate of the degree to which land use intensity must be reduced
r in the City to ensure that the transportation system operates at an acteptable level
l of service. Following preparation of Jower intensity land use scenarios, additIonal
model runs will be conducted to determine at what level of development the
I transportatIon system can be made to operate properly_
I .... Task 9 efforts will produce the Long-Term Transportation Improvement, Finanong
t and Land Use Control Plans. These, along With the near-term plans, Will be the final
product of the study. Task 9 Will be conducted in tandem with Task 8, With
~
, potential parallel improvements being modelled and refined. Separate sets of plans
I
I will be produced for each land use scenano modelled. The FinanaaJ and Land Use
Control Plans for each element will be consistent With the Transportation
1 Improvement Plan. Specifically, the Land Use Control Plan will ensure that only the
I assumed level of development occurs and the Financial Plan will only depend upon
revenue based on the assumed level of development but will also raisesuffioent
,
l revenue to meet the needs of the Transportation Improvement P\an.

Final Report and Presentation
j The Final Study report will be produced dunng Task 10. The first subtask will be to
, select a recommended set of long-term plans. This selectJon will be made in
I
i
consultation with City staff and officals and consider public input. The
1
, rei:ommended plans will then be produced in a manner conducive to further action
by the City. In addition, separate documentation of study results to support the
:
r recommended plans w1I1 also be produced.
[
Task 10 also Involves attendance at a total of up to four public meetmgs. in addition
l to the six workshop sessions conducted earlier in the project. The team views these
I meetl ngs as criti cal to th e su ccess of this study. They will provid e the team with
opportunities to present results to City staff and the public. This will create a forum
/ [ in orderto allow for completely informed decision making at the City level.
[ The following chart shows the relationship between the various activities within the
I study. This chart iIIu::iUciltes how the resutts of each task will be integrated into
those tasks which are bemg conducted simultaneously or subsequently. Emphasis
I - has been given to providing feedback between various elements of each plan where
