Subject: Traffic Calming Plans for Segovia Way and Harwich Drive.
Recommended Action Based on the findings contained in this report and the requirements of the Carlsbad Residential Traffic Management Program, staff recommends that Traffic and Mobility Commission support the proposed traffic calming plans on Segovia Way and Harwich Drive.
Background
The Carlsbad Residential Traffic Management Program (CRTMP) was approved by City Council in
2001 and was revised in 2011. This program was designed to address speeding on residential
streets. The program is a three-phase process, which offer solutions at increasing levels of cost
and complexity. The first phase is initiated when a concerned resident contacts the City. This
phase focuses on education and enforcement solutions and utilizes measures such as installation
of speed limit signs, pavement legends and working with the police department to provide
enforcement based on their availability.
Phase II utilizes cost-effective traffic management devices such as speed cushions, traffic circles,
high-visibility crosswalks and signs to help reduce speeds on neighborhood streets. The
measured critical speed, otherwise known as the 85th percentile street, must be at least 32 miles
per hour (mph) to be eligible for Phase II consideration. The Phase II process utilizes public input
to establish community support before a proposed traffic calming plan can be implemented. This
report describes two streets that are currently in the Phase II process.
Data
In response to speeding concerns, staff deployed the portable speed feedback signs on Segovia
Way and Harwich Drive (Exhibit 1). The measured criteria speeds for each of these streets are
summarized in Table 1.

STREET STREET LIMITS CRITICAL SPEED
Segovia Way Levante Street to Quebrada Circle 32 mph
Harwich Drive Tamarack Ave to 400 feet north of Edgeware Way 33 mph
The critical speeds measured on Segovia Way and Harwich Drive met the threshold to be eligible
for Phase II of the CRTMP.
Per the CRTMP Phase II process, staff invited residents within the study area to neighborhood
meetings to discuss traffic calming strategies and to receive feedback from residents on the
various concept plans staff developed to address speeding concerns. Details of the neighborhood
meetings on the two subject streets are summarized in Table 2.

Based on the feedback received at the neighborhood meetings, a preferred traffic calming plans
was selected by the attendees at the two neighborhood meetings. For Segovia Way, a traffic
calming plan consisting of seven speed cushions was selected. For Harwich Drive, a plan
consisting of four speed cushions was selected by majority of the meeting attendees.
After the meetings, letters were sent to the residents and property owners with proposed
features directly in front of their homes. This gives residents and property owners the
opportunity to express any specific concerns and for staff to make any adjustments to the
concept plan, if necessary. Based on the comments received, the preferred traffic calming plan
for each street was finalized (see Exhibits 2 and 3).
The CRTMP requires that the majority of the residents and property owners within the study area
must support the plan as determined by a mailed survey. The survey is considered valid if 50%
or more of the residents and non-resident owners return the completed survey. Positive support
for the plan is indicated by 67% or more of the returned surveys in support of the proposed plan.
The survey results for each of these streets are summarized in Table 3.
