INITIATED BY: Sandra Gravitt, 7410 Esfera Street, Carlsbad CA 92009
Recommend approval of the Esfera Street Traffic Calming Plan REQUESTED ACTION:
BACKGROUND:
DATA:
Speeding vehicles on Esfera Street has had a negative impact on the residential "feel"
and "character" of the neighborhood. Over the past several years, staff has been
working with the residents on Esfera Street to address their concerns about speeding
utilizing the Carlsbad Residential Traffic Management Program (CRTMP), the city's traffic
calming program. This segment of Esfera Street has met the CRTMP Phase II eligibility
criteria, making it possible to consider Phase II traffic calming measures when supported
by the residents of the neighborhood and approved by the City Council. Staff invited
residents to a neighborhood meeting to provide input to the proposed traffic calming
plan. After the neighborhood meeting, surveys were sent to the residents on Esfera
Street to determine if a majority of the residents supported the traffic calming plan.
Based on the results of the resident survey, staff is recommending that the Esfera Street
traffic calming plan be approved.
Esfera Street is a residential street in the southeast quadrant of the citV: Esfera Street is
improved with curb and gutter, sidewalks, and street lights. It has a curb to curb width
of 40 feet with a single travel lane in each direction, is not striped, with on-street
parking allowed on both sides of the street. This segment of Esfera Street is
approximately 1,775 feet in length, with a curvilinear alignment and southerly sloping
down-hill grades varying to nearly 12%. Traffic control on Esfera Street is provided by
STOP signs at Cadencia Street on the north, and a traffic signal at La Costa Avenue on
the south. The posted speed limit on Esfera Street is 25 miles per hour. There are 38
single family residences on this portion of Esfera Street.
The CRTMP is a three-phase process. Phase I solutions include the installation of speed
limit signs and pavement legends, deployment of temporary speed feedback signs, and
police enforcement. As required by the CRTMP, Phase I was completed for Esfera Street
prior to consideration of Phase II. In order for a street to qualify for Phase II, streets are
required to have a critical speed (the speed at which 85% of the vehicles surveyed are
driving at or below) of 32 miles per hour or greater. This segment of Esfera Street was
found to have a critical speed of 39 miles per hour.
Phase II of the CRTMP utilizes cost effective traffic management features such as
residential STOP signs to reduce the uncontrolled length of a street to a "residential

neighborhood scale". This is typically accomplished by restricting the uncontrolled
length of a street to approximately 500 -1,000 feet by installing residential STOP signs.
Drivers tend to comply with speed limits in residential neighborhoods when
uncontrolled street lengths are less than 1,000 feet. Esfera Street from Cadencia Street
to Piragua Street is approximately 1,775 feet in uncontrolled length. Four streets
intersect this segment of Esfera Street; Casca Way, Fosca Street/Fosca Way, Cabo Way
and Piragua Street; all four are controlled by minor approach STOP signs at Esfera
Street. The Esfera Street traffic calming plan proposes installing residential STOP signs
on Esfera Street at Fosca Street/Fosca Way and Piragua Street to reduce the
uncontrolled lengths of the road segments to a "residential scale" and thereby reduce
vehicle speeds.
As part of the Phase II process, a neighborhood meeting was held on May 9, 2012, at La
Costa Heights Elementary School to present the proposed Phase II traffic calming plans
to all of the residents of the 36 homes along Esfera Street. Four people attended the
meeting, representing four homes. At the meeting, staff answered questions from the
residents regarding the proposed traffic calming plan and worked with the residents to
establish consensus for the plan.
Implementation of the Phase II plan requires that a majority of the residents on the
street support the plan as determined by responses to a mailed resident survey. The
survey is considered valid if 50% or more of the residents and non-resident owners
return the completed survey. Support for the plan is indicated by 67% or more of the
returned surveys in support of the proposed plan. 38 surveys were mailed out to
residents and non-resident owners for the Esfera Street traffic calming plan. 22 surveys
were returned for a 61% return rate. Of those 22 surveys, 17 or 77% were in support of
the proposed plan.
In summary, the Esfera Street traffic calming plan proposes installing residential STOP
signs on both legs of Esfera Street at Fosca Street/Fosca Way, and on both legs of Esfera
Street at Piragua Street (see attached Exhibit 1). This would reduce the uncontrolled
length of the segments of Esfera Street to a "residential scale" as follows:
• Cadencia Street to Fosca Street/Fosca Way -900 feet in length
• Fosca Street/Fosca Way to Piragua Street -875 feet in length
This reduction of the uncontrolled lengths of the segments of Esfera Street should result
in a reduction in vehicle speeds.
RECOMMENDATION:
Based on the findings contained in this report, and the requirements of Phase II of the
Carlsbad Residential Traffic Management Program, the Traffic Safety Coordinating
Committee recommends approval of the Esfera Street traffic calming plan.
