We are pleased to submit the enclosed recommendation and supporting documentation

SEGMENTS WITH SPECIAL CONDITIONS
The following segments surveyed had recommended speed limits that were 5 miles per
hour (mph) or more below the critical speed due to conditions not readily apparent to the
driver. Each segment is discussed below.
Segment 33 — Jefferson Street — Westward Ho to Highway 111
This segment is currently posted at 55 mph and has three through lanes in each direction
with an ADT of 24,330 vehicles per day. The adjacent land is commercial along the 0.49 -
mile -long segment. The 85th percentile speed is 50 mph and would normally justify a 50 -
mph posted speed limit. This segment is identified as a land or facility that generates high
concentrations of bicycles and pedestrians. The segment has bike lane presence along
the corridor. Because this segment is established as a land or facility that generates high
concentrations of bicycles and pedestrians, an additional 5 mph reduction can be applied.
It is recommended that the speed limit be posted at 45 mph for the above reasons. This
recommendation falls within the limitations requiring the recommendation be no more
than 12.4 mph under the 85th percentile speed.

JUSTIFICATION:
This segment of Jefferson Street is a six -lane divided roadway. The adjacent land uses are solely residential golf communities. The
speed data shows an 85th percentile of speed of 51.4 mph, which may suggest a speed limit of 50 mph. A review of the accident
history revealed that this segment had two (2) speed related accidents, one (1) fatality, one (1) involved a serious injury and one (1)
involved a bicyclist, which ranked it as one of the top locations in the City that involved fatality and/or serious injury accidents. In
accordance with CVC 22358.7(a)(1), this segment is designated as a "Safety Corridor" which allows the speed limit to be reduced by 5
mph. Collectively, this segment and other City streets designated as a "Safety Corridor" did not exceed more than 20% of City
maintained streets. Therefore, it is recommended that the existing 50 mph speed limit be reduced to 45 mph.
