DEPARTMENT:' ENGINEERING -TRAFFIC SAFETY COMMISSION ----------------------
SUBJECT: SPEED ZONE ON ALGA EOAD
STATEMENT OF THE MATTER
"t~
Initial:
Dept. Head (
City Atty Vfd
City Mgrl?_ ~
At their June 1, 1981 meeting, the Traffic Safety Commission reviewed a
request from the Police Chief to consider reducing the speed limit on
Alga Road between El.Camino Real. and Alicante. The speed limit is pres-
. ently 55 mph.
The Commission recommended that the speed limit be reduced to 45 mph on
Alga Road £pr uhe following reasons:
1. Traffic volumes on this road are about 6500 vehicles per day. ,,
2. There is an unexpected lateral transition due to narrowing of the
!oadway which has a record of speed-relate~ ~~~idents .
. 3. The curve and pavement slope in the are~ can cause drivers to over-
react in the transition area. . .,
Widening of .Alga Road is expected to occur within a year. After widen-
ing, the above conditions will be r~moved, and the Commission recommended
that· a radar a11d accident survey be taken to· (;)Stablish new speed zoning
~t the 85th p~rcentile ~evel. The Vehicle Code requires that an engineer-
ing and traffic survey be conducted to form the basis of the reduced speed.-~
zon~. The required report is attached.
FISCAL IMPACT .

June 9, 1981
SUBJECT: REPORT OF ENGINEERING AND TRAFFIC SURVEY HITH A RECOMMENDATION THAT
THE EXISTING 55 MPH ZONE BE REDUCED TO A 45 MPH ZONE ON ALGA ROAD
FROM 500' EAST OF ALICANTE ROAD TO 300' EAST OF EL CAMINO REAL
The vehicle code in Section 22358 grants a local authority, upon the basis of
an engineering and traffic survey, the power by ordinance to determine and
declare a prima facie speed limit is reasonable and safe. The declared prima
facie speed limit shall b~ effective when appropriate signing giving notice
is erected upon the street.
The Engineering Division has made such a survey and found the following.
The existing 55 MPH speed limit should be reduced to 45 MPH for the following
reasons:
1. The traffic volumes on this road are about 6500 vehicles per day.
2. There is an unexpected lateral transition due to narrowing of the
roadway which has a record of speed-related accidents.
3. The curve and pavement slope in the area can cause drivers to overreact
in the transition area.
4. Additional roadway striping and curb painting will make the area more
visible. The area can be safely negotiated at 45 MPH. At speeds
greater th~n this, there is the possibility of accidents.
After the street is widened (which is expected within a year) and the above
conditions removed, it is recommended a radar and accident survey be taken
to establish new speed zoning at the 85th percentile level.
