CC - Item 4C - Approval of First Addendum to 1999 Engineering and Traffic Survey - Valley Boulevard stafleport
TO: HONORABLE MAYOR
AND MEMBERS
ROSEMEAD CITY COUNCIL
FROM: FRANK G. TRIPEPI, CITY MANAGER
DATE: SEPTEMBER 7, 1999
RE: APPROVAL OF FIRST ADDENDUM TO 1999 ENGINEERING AND TRAFFIC
SURVEY- VALLEY BOULEVARD
Last January, the City Council adopted the "Citywide Engineering and Traffic Survey." The survey
included 36 street segments within the City. However, because of the Valley Boulevard
reconstruction project,three streets-Valley Boulevard, Mission Drive and De Adalena Street-were
not surveyed at that time. Upon completion of construction on the street, staff began surveying
Valley Boulevard in mid-July,thus allowing traffic to return to "normal"pre-construction patterns.
Mission Drive and De Adalena Street, will be surveyed next month to take into account normal
school traffic on those streets.
The recent survey indicates that "85th percentile" speeds on Valley Boulevard did not exceed 37
miles per hour. Accordingly, staff is recommending that the City Council approve the survey and
retain the current 35 mph speed limit on Valley Boulevard.
RECOMMENDATION:
It is recommended that the City Council approve the Valley Boulevard addendum to the "1999
Engineering and Traffic Survey."
