ITEM TITLE:
Ordinance increasing the Speed Limit on Olympic Parkway between 1-
805 northbound ramps and Brandywine Avenue from 35 mph to 45 mph.
SUBMITTED BY:
Director of Engineering'tlJ ;f.
Interim City Manager~
(4/Sths Vote: Yes_ NoX)
REVIEWED BY:
With the recent completion of roadway improvements on Olympic Parkway near I-80S, an
Engineering and Traffic Survey (commonly referred to as a "speed survey") was done for the
segment of roadway between the northbound I-80S on/off ramps and Brandywine Avenue. Based on
the results of this speed survey, and pursuant to the authority under Chula Vista Municipal Code
Section 10.48.020, City staffhas determined that the speed limit on Olympic Parkway between I-80S
northbound ramps and Brandywine Avenue should be increased from 35 mph to 45 mph.
RECOMMENDATION:
That Council adopt the Ordinance increasing the speed limit on Olympic Parkway between I-80S
northbound ramps and Brandywine Avenue.
BOARDS AND COMMISSIONS: The Safety Commission, at their meeting of May 11, 2006,
voted to concur with staffs recommendation to increase the posted speed limit from 35 mph to 45
mph.
DISCUSSION:
Over the past six years, improvements to the Orange A venue/Olympic Parkway interchange with 1-
805 have been underway. The project widened Olympic Parkway east of the northbound I-80S on
and off ramps. Because this represents a significant change in the roadway, City staff was required
to conduct an Engineering Traffic Survey, commonly referred to as a "speed survey", to determine
the appropriate speed limit for the new roadway configuration.
Prior to construction ofthe recently completed improvements, Olympic Parkway, immediately east
ofl-805, was predominantly a two-lane roadway. Speed limits were posted, based on supporting
speed surveys, for 35 mph from I-80S to Brandywine Avenue. With the new roadway
improvements, Olympic Parkway is now a six-lane roadway from I-80S east, past Brandywine
A venue. It is this significant change in roadway characteristics that resulted in the need for a revised
speed survey to be completed along Olympic Parkway.
The speed survey conducted for the new ly widened segment of Olympic Parkway was performed in
accordance with the California Vehicle Code which indicates that the posting of speed limits be

determined by an Engineering and Traffic Survey which shall include: (l) prevailing speeds as
determined by traffic engineering measurements; (2) accident records; and (3) traffic/roadside
conditions not readily apparent to the driver. The Manual on Uniform Traffic Control Devices (2003
MUTCD) gives additional guidance, stating that speed limits should be established at the nearest 5
mph increment to the 85th percentile speed (defined as the speed.which 85 percent of the traffic is
moving at, or slower than) unless engineering judgment recommends otherwise based on roadway
characteristic factors. According to the MUTCD, speed limits set higher than the 85th percentile
speed are not generally considered reasonable and safe and limits below the 85th percentile do not
facilitate the orderly movement of traffic. Speed limits established on the 85th percentile basis
conform to the consensus ofthose who drive the street as to what speed is reasonable and safe, and
are not dependent on the judgment of one or a few individuals. Only when roadside development
results in traffic conflicts and/or unusual conditions that may not be readily apparent to drivers may
speed limits be posted below the 85th percentile speed.
Early in the Engineering and Traffic Survey process it was determined that the limits ofthe previous
speed survey covering this stretch of road needed to be modified in accordance with the new
roadway configuration. Previous surveys analyzed Olympic Parkway/Orange Avenue in this area
from Melrose Avenue to Oleander Avenue and from Oleander Avenue to Brandywine, assigning a
speed limit to each segment. Now that Olympic Parkway widens to six lanes at the northbound 1-805
ramps, the survey boundaries should be modified to allow for a different speed limit, starting at the
northbound ramps, to accommodate the new six lane configuration. This boundary adjustment can
be seen in the data collected for the Engineering and Traffic Survey as summarized in the following
table:

Meeting Date 12/12/06
On May II, 2006, this speed survey was brought before the Traffic Safety Commission for their
consideration. The Traffic Safety Commission approved staffs recommendation to increase the
speed limit on Olympic Parkway from 1-805 northbound ramps to Brandywine Avenue from 35 mph
to 45 mph. In addition, the Commission approved the recommendation to modify the survey's
westerly boundary from Oleander to the 1-805 northbound ramps and that Schedule X ofthe register
maintained in the office of City Engineer be revised to include this revised speed limit.
A resident who lives on Rivera Street adjacent to Olympic Parkway raised a concern that the
increased speed that vehicles would be traveling at would result in an increase in the noise generated
by the vehicle traffic. An acoustical assessment report was prepared in July of2000 as part of the
Mitigated Negative Declaration (MND) for the Olympic Parkway widening project. That report
modeled future noise from the roadway based on an anticipated speed of 50 mph at the ultimate six-
lane configuration. The mitigation measures for the street widening project, included noise walls
that are designed based on that speed and road configuration. These walls were constructed as part
of the widening project. No additional measures relating to noise were required by the MND.
Based on the low accident rate, the design speed as outlined in the Engineering/Traffic Survey, and
roadway characteristics, staff recommends modifying the survey's westerly boundary from Oleander
Avenue to the 1-805 Northbound ramps and increasing the existing speed limit of35 mph to 45 mph.
Staff also recommends that Schedule X ofthe register maintained in the office of the City Engineer
be revised as follows:
10.48.020 Schedule X - Established Speed Limits in Certain Zones - Designated
Name of Street Beginning At Ending At Proposed Speed Limit
Olympic Parkway 1-805 Northbound Brandywine Ave 45 mph
ramps
With the approval of the proposed speed limit increase, staff would make the recommended changes
to the speed survey boundary and Schedule X as discussed in the report and supported by the Safety
Commission.
ENVIRONMENTAL STATEMENT:
The Environmental Review Coordinator has reviewed the proposed project for compliance with the
California Environmental Quality Act (CEQA) and has determined that the project (increasing the
speed limit from 35 mph to 45 mph) qualifies for a Class I categorical exemption pursuant to
Section 15301 (c) (Existing Facilities) of the State CEQA Guidelines because it involves the on-going
operation of an existing facility. Thus, no further environmental review is necessary.
DECISION MAKER CONFLICTS:
Staff has reviewed the property holdings of the City Council and has found no property holdings
within 500 feet of the boundaries of the property that is the subject of this action.

FISCAL IMPACT:
The cost to replace existing speed limit signs and pavement legends is approximately $5,000.00.
This cost estimate includes sandblasting the existing pavement legends - work that cannot be done
by City crews. City crews will do the installation of the new speed limit signs and the pavement
legends as part of the Signing and Striping CIP project TF-332 (Gas Tax).

Commission Discussion: Chair White asked what was different between April's Meeting and this present
meeting, and also why the recommendation to do bike lanes was not in the report. Senior Civii Engineer
Moneda replied that action regarding bike lanes is directly related to the number of lanes, which needs to be
decided on by the Commission before anything can be implemented.
Public hearing opened.
The following persons spoke in oppOSition to staff's recommendation: (favored all-way stop)
1) Albert Servin, 1319 Raven Avenue
2) Ron Garcia, 1349 Raven Avenue
3) Harvey Currey, 1325 Raven Avenue
4) Bill Odle, 1211 Raven Avenue
5) Gifford Justice, 1343 Raven Avenue
6) Ed Dulude, 1336 Raven Avenue
7) Fernando Felix, 449 Sparrow Street
a. Unable to attend meeting, but sent an email through Ms. Walters that was added in as part
of meeting. Also favored all-way stop.

Commission Discussion: Vice-Chair A1-Ghafry mentioned the fact that an improperly installed stop sign can
give a false sense of security. It can actually go so far as to increase speeds, once cars are through stop
sign, so as to make up for lost time. He did however say that City staff did a great job, and supported staffs
recommendation Commissioner Rosario stated that he was in favor of all-way stop installation.
Commissioner Perrett was also in favor of all-way stop, however held some misgivings about lane changes
and striping. He and Commissioner Gave were in favor of all-way stop the previous Commission Meeting as
well.
MSC (White/Rosario) to approve all-way stop installation (5-1-1) A1-Ghafry (no); Willett absent.
7. Report on Speed Limit Revision on Olvmpic Parkway between the 1-805 Northbound ramps and
Brandvwine Avenue.
Brief presentation by Principal Civil Engineer Rivera. Due to the recent completion of the roadway
improvements on Olympic Parkway, staff completed an Engineering and Traffic survey for this segment.
Based on the results of this speed survey and pursuant to the authority under the Chula Vista Municipai Code
Section 10.48.020, city staff has detemnined that the speed limit on Olympic Parkway between 1-805
Northbound ramps and Brandywine Avenue should be Increased from 35 mph to 45 mph.
Staff Recommendation: That Safety Commission concur with staffs recommendation to recommend to
Council to modify the survey's westerly boundary from Oleander Avenue to the 1-805 Northbound ramps, to
increase the existing speed limit of 35 mph to 45mph, and that Schedule X of the register maintained in the
office of the City Engineer be revised to include this revised speed limit.
Public hearing opened.
The following person spoke in opposition to staffs recommendation:
1) Richard Allshouse, 640 Rivera Street
Public hearing closed.
Commission Discussion: Vice-Chair A1-Ghafry stated that if you do not post the speed at the 85'" percentile,
it becomes a speed trap due to the inability by police to enforce it. Some discussion of noise ievels, as
mentioned by pubiic speaker, however, with lack of expert on regulations, discussion was nothing more than
conjecture.

8. A11-Wav Stop at the Intersection of Emerson Street and Del Mar Avenue
Brief presentation by Senior Civil Engineer Moneda. City Staff received a request from Sandra Sato Ii . gat
224 Emerson Street concerning excessive speeding along Emerson Street and requested an all- y stop
installation along Emerson Street to inhibit the fast fiow of traffic. Mer reviewing the location staff d ided that
the intersection at Del Mar Avenue would be the most viable location for an all-way stop install on. Staff is
forwarding this report to the Safety Commission for consideration. Staff also mentioned that th received no
calls on this item,.
Commission Discussion: With lack of public support, as shown by zero attendance for ublic hearing to be
held, it was simply mentioned that volumes are almost identical between Emerson nd Del Mar, and the
Raven Avenue item, however, they are worlds apart in terms of community outcry. Li e discussion based on
this.
