PUBLIC WORKS DEPARIMEN
TO: City Council
FROM: City Manager
MEETING DATE: August 5, 1987
AGENDA TITLE: Revised Policies on Speed Limit Signs and Street Centerlines
RECOMMENDED ACTION: Informational only.
BACKGROUND INFORMATION: During the recent Council discussion concerning
Lakeshore Vi age tra fic controls, staff indicated some unwritten policies
would be reviewed and formalized. Written policies regarding speed limit
signs and street centerlines are attached for the Council's information.
Charges from past practices are:
° 25 mph signs - Signs will be installed on approximately 20 residential
streets near the intersection of high speed streets (40 mph or higher).
° Centerlines on curved streets - More curved streets will be striped
with a centerline.
° Fewer streets with centerlines - Past practice was to install a
centerline on streets such that a motorist would be no more than two
blocks from a street with a centerline. Under the new policy, streets
such as Royal Crest Drive, Tamarack Drive, and Daisy Avenue do not
need centerlines. They will, however, be maintained until the street
is resurfaced, at which time they will not be repainted.
