Meeting Date 10/2/19
Currently, the existing posted speed limit on East ‘H’ Street, between Buena Vista Way and
Southwestern Drive is 45 mph (Segment 1). The existing posted speed limit on East “H” Street
between Southwestern Drive and Otay Lakes Road is 35 mph (Segment
2). The E&TS for both segments have expired, and roadway conditions are consistent between
both segments.
City staff completed a speed survey for above segments in accordance with the California
Vehicle Code. As described in the California Vehicle Code, the survey shall include:
(1) Prevailing speeds as determined by traffic engineering measurements;
(2) Accident records;
(3) Traffic/roadside conditions not readily apparent to the driver.
Physical Conditions
The following information describes the existing conditions along East ‘H’ Street between Buena
Vista Way and Otay Lakes Road:
Classification Between Buena Vista Way and Otay Lakes Road – Six Lane Major.
Length/Width – 2,444 feet (0.46 miles) long and 84’ to 113’ wide, including raised
median.
Average Daily Traffic: 42,997 (2015)
Number of Lanes: 6 lanes (3 per direction).
Existing Speed Limits – Posted 45 (Segment 1) and 35 mph (Segment 2).
85% Percentile Speed: Segment 1 is 46 mph. Segment 2 is 46 mph.
Striping – Six lanes of traffic, bike lanes, left-turn and right-turn pockets.
Parking – Parking is not allowed along both segments.
Bike Lanes in both directions.
Horizontal Alignment – Horizontal Curve east of Southwestern Drive with a radius of
2000’ over a length of 557’ yields a design speed over 50 mph.
Vertical Alignment – Vertical Sag east of Southwestern Drive with a grade change of
4.5% over 500’ indicates a design speed over 50 mph
Accident Rate History – The accident rate at this segment is 0.32 accidents per million
vehicle miles, which is lower than the rate of 1.36 for similar roadways in the State of
California.
Traffic Calming
Segment 2 is the only segment with a proposed speed increase. Given its short length and major
roadway classification, no traffic calming measures are feasible. The MUTCD recommends that
roadway segments be a minimum of 0.25 miles; therefore, a speed increase on Segment 2 and
merging it with Segment 1 is the recommended approach.

Speed Enforceability
If the proposed speed increase is not approved, the following are the only means of enforcing
speed on Segment 2:
Basic Speed Law: police car matches speed of vehicle and determines that speed is
unsafe for current conditions. Infeasible due to insufficient police availability and the
segment is too short.
Maximum Speed Law: use RADAR/LiDAR methods to enforce speed limit of 65 mph.
If the proposed speed limit is approved, police can use RADAR/LiDAR to enforce the approved
posted speed limit.
CONCLUSION:
When speed limits are appropriately established the following objectives are achieved:
- Meaningful, unambiguous enforcement
- Voluntary public compliance
- Clear identification of the unreasonable violator
- Elimination of unjustifiable “tolerances” of higher speed travel
Based on the 85th percentile speed of the roadway, as well as a low collision rate outlined in the
Engineering/Traffic Survey, staff has determined that the speed limit on East ‘H’ Street between
Buena Vista Way and Otay Lakes Road be 45 mph. Segment 1, between Buena Vista Way and
Southwestern Drive, is proposed to retain the 45 mph posted speed limit. Segment 2,
Southwestern Drive and Otay Lakes Road (Segment 2) is proposed to be increased from 35 mph
to 45 mph.
Should the City Council establish the 45 mph speed limit, Schedule X of the register maintained
in the Office of the City Engineer be amended to reflect the speed limit increase:
East ‘H’ Street, Buena Vista Way and ending at Otay Lakes Road, proposed Speed Limit
45 mph.
FISCAL IMPACT:
The increase of the speed limit would require the posting of two (2) new speed limit signs and
speed limit legends. This work will be funded by an existing Traffic Engineering Capital
Improvement Project, TRF0332, Signing and Striping Program.

Eliminating the 2-hour parking restriction on Vance Street and the need for residents to obtain a
special parking permit will no longer be needed.
Staff recommends that the Safety Commission adopt the resolution and recommend to the City
Council repeal Ordinance No. 3075 to eliminate the 2-hour time-limited parking along the 500
block of Vance Street and amend Schedules VI and XVI of the Register of Schedules, which is
maintained by in the Office of the City Engineer.
