EXECUTIVE SUMMARY
Snyder Partners proposes to develop an office complex project on the southwest corner
of Romaine Avenue and Seward Street in the Hollywood community of the City of Los
Angeles. The project consists of three buildings totaling approximately 241,568 square
feet of office and minor ancillary use. An approximate 710-space parking structure will
also be constructed as a part of the project.
For study purposes, it has been assumed that the project will be completed by the year
2010. Upon completion, it is estimated that the project will generate approximately
2,337 new trips per day, including 336 AM and 310 PM peak-hour trips.
The traffic study presented herein analyzed existing (2007) and future (2010) AM and
PM peak-hour traffic conditions at 18 critical intersections and daily traffic conditions on
three residential street segments in the vicinity of the project site. The cumulative traffic
conditions attributable to 100 potential related projects in the surrounding area were
also analyzed. It is anticipated that prior to mitigation, the project would have significant
traffic impacts at the following 11 study intersections:
o Sunset Boulevard & Highland Avenue
o Santa Monica Boulevard & Highland Avenue
o Santa Monica Boulevard & Cahuenga Boulevard
o Santa Monica Boulevard & Vine Street
o Santa Monica Boulevard & Gower Street
o Willoughby Avenue & Seward Street
o Melrose Avenue & La Brea Avenue
o Melrose Avenue & Highland Avenue
o Melrose Avenue & Seward Street
o Melrose Avenue & Rossmore Avenue/Vine Street
ii
o Melrose Avenue & Gower Street (N.)
Feasible mitigation measures could be identified only for the intersections of Santa
Monica Boulevard & Vine Street, Santa Monica Boulevard & Gower Street, Willoughby
Avenue & Seward Street, and Melrose Avenue & Rossmore Avenue/Vine Street.
Significant project traffic impacts, therefore, would remain at the other seven study
intersections above.
An analysis was also performed for three nearby residential streets to determine
whether the project might significantly impact the surrounding residential streets. No
significant residential street impacts were identified for the project.
In addition, project traffic impacts were analyzed for Congestion Management Program
(CMP) locations. The study intersection of Santa Monica Boulevard & Highland Avenue
is also a CMP intersection, and is expected to be significantly impacted according to the
CMP criteria as well as the more conservative City of Los Angeles criteria. No
significant regional traffic impacts were determined for any other CMP arterial or
freeway monitoring locations.

INTRODUCTION
The project under consideration is the development of an office complex on the
southwest corner of Romaine Avenue and Seward Street in the Hollywood community
of the City of Los Angeles, as shown in Figure 1, Project Site Vicinity Map. This site,
which has an address of 959 Seward Street, is vacant. The office complex will be
comprised of three buildings totaling approximately 241,568 square feet, including 4,000
square feet for a commissary/restaurant, a minor ancillary use, and an adjoining parking
structure with approximately 710 spaces.
Crain & Associates has assessed the potential impacts of the proposed project on the
surrounding roadway system. The analysis that follows was prepared in accordance
with the assumptions, methodology and procedures approved by the City of Los
Angeles Department of Transportation (LADOT). This report presents the results of an
analysis of existing (2007) and future (2010) traffic conditions before and after
completion of the project. The analysis contains a detailed evaluation of traffic

PROJECT DESCRIPTION
Snyder Partners proposes to develop an office complex and parking structure at 959
Seward Street. The project site is on the southwest corner of Romaine Avenue and
Seward Street in the Hollywood community of the City of Los Angeles. As shown in
Figure 3, Project Site Plan, the office complex will be comprised of three buildings
totaling approximately 241,568 square feet, including 4,000 square feet for a
commissary/restaurant, a minor ancillary use. The commissary/restaurant will be used
primarily by those working on-site, but it will also be open to the public. The site is
currently vacant as the previous uses were removed in March 2005. For purposes of a
conservative traffic analysis, a project completion year of 2010 has been assumed.
Parking for the project will be provided on-site within a multi-level parking structure
containing approximately 710 spaces. This parking supply is expected to adequately
satisfy the needs of the project. Vehicular access into and out of the site will be via one
two-way driveway on Seward Street and one two-way driveway on Romaine Avenue.

Existing (2007) Traffic Volumes
Traffic volumes for existing conditions at the 18 study intersections were obtained from
manual traffic counts conducted in November 2006 by Crain & Associates and its
subcontractor. The counts covered the weekday morning and afternoon peak commute
periods.
Peak-hour volumes were determined individually for each intersection based on the
combined four highest consecutive 15-minute volumes for all vehicular movements at
the intersection. A growth factor of one percent was applied to the 2006 volumes to
represent existing volumes for the year 2007. Weekday peak-hour volumes are further
discussed in the following pages and depicted in Figures 4(a) and 4(b). The manual
intersection traffic count data sheets are provided in Appendix A.
14
In addition to the intersection counts, daily traffic volume (ADT) counts were conducted
during a typical weekday in December 2006 on three residential street segments
located near the project site that could experience project traffic. The ADT volumes
from 2006 were growth-factored by one percent to reflect existing 2007 conditions. The
ADT traffic count data sheets are provided in Appendix A.
Information pertaining to intersection widths and geometrics, on-street parking
restrictions, and traffic signal operations were obtained from both field checks and City
engineering plans. The existing lane configuration and traffic control conditions for the
18 study intersections are illustrated in Appendix B.

LADOT Bus Service
DASH Hollywood provides local access throughout the Hollywood community.
Near the project site, DASH Hollywood operates along Fountain Avenue, with stops
provided at Vine Street, Cahuenga Boulevard, Cole Avenue, Wilcox Avenue,
Seward Street, Las Palmas Avenue and Highland Avenue. Stops are also
provided at the Hollywood/Highland and Hollywood/Vine Metro Red Line Transit
Stations. DASH Hollywood operates everyday, including holidays, on
approximately 30 minute headways. The Hollywood DASH provides transfer
opportunities to the Hollywood/Wilshire DASH and the Hollywood/West Hollywood
DASH, further extending access to and from the project site.
When transfer opportunities are considered, the project is well served by public transit.
Thus, it is expected that some of the person trips generated by the project will utilize
public transportation as their primary travel mode instead of private vehicles.
Analysis of Existing (2007) Traffic Conditions
An analysis of existing weekday AM and PM peak-hour traffic conditions was performed
at the 18 study intersections listed below. These intersections were determined in
consultation with LADOT. Thirteen of these intersections are signalized and five of
them are controlled by Stop signs.
1. Sunset Boulevard & Highland Avenue
2. Sunset Boulevard & Cahuenga Boulevard
3. Santa Monica Boulevard & La Brea Avenue
4. Santa Monica Boulevard & Highland Avenue

18. Melrose Avenue & Gower Avenue (N.) * Two-way stop-sign controlled intersection ** All-way stop-sign controlled intersection
The traffic analysis was performed through the use of established traffic engineering
techniques. The methodology used in this study for the analysis and evaluation of
traffic operations at each study intersection is based on procedures outlined in Circular
Number 212 of the Transportation Research Board.1 In the discussion of Critical
Movement Analysis (CMA) for signalized intersections, procedures have been
developed for determining operating characteristics of an intersection in terms of the
Level of Service (LOS) provided for different levels of traffic volume and other variables,
such as the number of signal phases. The term "Level of Service" describes the quality
of traffic flow. Levels of Service A to C operate quite well. Level D typically is the level
for which a metropolitan area street system is designed. Level E represents volumes at
or near the capacity of the highway which might result in stoppages of momentary

25
duration and fairly unstable flow. Level F occurs when a facility is overloaded and is
characterized by stop-and-go traffic with stoppages of long duration.
A determination of the LOS at an intersection, where traffic volumes are known or have
been projected, can be obtained through a summation of the critical movement volumes
at that intersection. Once the sum of critical movement volumes has been obtained, the
values indicated in Table 1 can be used to determine the applicable LOS.
Table 1
Critical Movement Volume Ranges* For Determining Levels of Service
Maximum Sum of Critical Volumes (VPH)
Level of Two Three Four or Service Phase Phase More Phases A 900 855 825
B 1,050 1,000 965
C 1,200 1,140 1,100
D 1,350 1,275 1,225
E 1,500 1,425 1,375
F --------------Not Applicable--------------- Note: * For planning applications only, i.e., not appropriate for operations
and design applications.
"Capacity" represents the maximum total hourly movement volume of vehicles in the
critical lanes which has a reasonable expectation of passing through an intersection
under prevailing roadway and traffic conditions. For planning purposes, capacity
equates to the maximum value of Level of Service E, as indicated in Table 1. A
capacity of 1,200 VPH was utilized for the two-way stop-sign controlled intersections of
Santa Monica Boulevard/Seward Street, Romaine Street/Highland Avenue, Willoughby
Avenue/Seward Street, and Melrose Avenue/Seward Street. A capacity of 1,000 VPH
26
was utilized for the all-way stop-sign controlled intersection of Romaine Street/Seward
Street. The CMA values used in this study were calculated by dividing the sum of
critical movement volumes by the appropriate capacity value for the type of signal
control present at the study intersections. Thus, the LOS corresponding to a range of
CMA values is shown in Table 2.
Table 2 Level of Service
As a Function of CMA Values
Level of Range of Service Description of Operating Characteristics CMA Values A Uncongested conditions; vehicles clear in a < 0.60 single cycle.
B Similar to above. >0.60 < 0.70
C Light congestion; occasional backups on >0.70 < 0.80 critical approaches.
D Congestion on critical approaches, but >0.80 < 0.90 intersection functional. Vehicles required to wait through more than one cycle during short peaks. No long-standing lines formed.
E Severe congestion with some long-standing >0.90 < 1.00 lines on critical approaches. Blockage of intersection may occur if traffic signal does not provide for protected turning movements.
F Forced flow with stoppages of long duration. > 1.00
By applying this analysis procedure to the study intersections, the CMA value and the
corresponding LOS for existing (2007) traffic conditions were calculated, as shown in
Table 3. The CMA calculation worksheets for existing conditions are included in
Appendix E.
As shown in Table 3, relatively good Levels of Service (LOS A to LOS C) have been
determined for half of the study intersections, while an additional six intersections are
27
currently operating at LOS D or better during one or both peak hours. The remaining
three study intersections currently operate at LOS E or F during one or both peak hours.
