TRAFFIC SAFE1Y COMMISSION
STAFF REPORT
COMMISSION MEETING OF: July 6, 1992 ITEM NO. 6B
LOCATION: South Carlsbad
INITIATED BY: Morris Rabin, 7717 Morada Street, Carlsbad, CA 92009
REQUESTED ACTION: Establish a prima facie speed limit on the following streets or
segments of the street: Romeria Street, Gibraltar Street, Vieja
Castilla Way, Estrella De Mar and Corintia Street
BACKGROUND:
DATA:
Mr. Rabin previously attended the Traffic Safety Commission meeting of October 7,
1991 when golf cart issues were discussed. At that meeting the Commission was
notified that many of the subject streets did not qualify as a residence district and,
therefore, the streets did not have a prima facie 25 mile per hour speed limit.
Mr. Rabin has requested staff to conduct an engineering and traffic survey on the
above listed streets. Based upon the results of the survey, he asked that the Traffic
Safety Commission recommend a prima facie speed limit.
Sections 2235 7 and 22358 of the California Vehicle Code authorizes local authorities
to establish a prima facie speed limit on the basis of the results of an engineering and
traffic survey. Staff conducted the survey and has included the data for each street.
The recommended prima facie speed limit for each street or street segment is
indicated on Table A.
