HomeMy WebLinkAboutAgenda Report - August 5, 1981 (49)CHANGES APPROVED Council was apprised that on a number of occasions
IN COMMERCIAL during the last few years, commercial developers
SHOPPING CENTER have submitted plans including driveways with
DRIVEWAY curved curb returns rather than the three foot flares
STANDARD that are standard. Staff have commented that
these driveways did not meet our City standards
and the plans were revised. The developers of
the Mo' ,tsnne Village Center brought new design
criteria for high volume commercial driveways
to our attention and have asked that their
request for this type of drive be taken to the
City Council.
The reason behind the City's existing standard
is mainly that there should be a clear difference
between public and private street facilities.
Streets and alley approaches had curb returns
and driveways had flares.
However, use of curb returns on commercial
driveways is increasing in other cities, par-
ticularly in shopping centers where volumes are
high. These driveways, with proper design, can
improve traffic flow by allowing turns to be
made similar to turning from one street to
another. This will reduce rear end accidents
and improve street capacity. Separation of
ingress and egress by medians eliminates delays
due to ears using the center of the drive
and blocking other traffic. Use of curbing and
lanes perpendicular to the street for some
distance into the parking lot eliminates conflicts
between cars maneuvering wit:iin the parking lot
and those waiting to exit. The driveway section
between the returns will continue to be concrete
as driveways are now, this will maintain the
division between public and private streets.
Sketches were provided for Council's perusal.
Following discussion, Council, on motion of
Councilman Pinkerton, Murphy second, directed
the Public Works Director to develop standards
and criteria for special commercial driveways and
approved the installation of a special commercial
driveway at the Mokelumne Village Center.

COUNCIL COMMUNICATION
SUBJECT: Approve Change In Commercial Shopping Center Driveway Standards
RECOMMENDED ACTION: That the City Council direct the Public Works Director
to develop stan ars and criteria for special commercial driveways and that
they approve the installation of a special commercial driveway at the
Mokelumne Village Center.
BACKGROUND INFORMATION: On a number of occasions during the last few years,
commercial eve oilers ave submitted plans including driveways with curved
curb returns rather than the three foot flares that are standard. We have
commented that these driveways did not meet our standards and the plans were
revised. The developers of the Mokelumne Village Center brought new design
criteria for high volume commercial driveways to our attention and have asked
that their request for this type of drive be taken to the City Council.
The reason behind our existing standard Is mainly that there should be a
clear difference between public and private street facilities. Streets and
alley approaches had curb returns and driveways had flares.
However, use of curb returns on commercial driveways is increasing in other
cities, particularly in shopping centers where volumes are high. These drive-
ways, with proper design, can improve traffic flow by allowing turns to be
made similar to turning from one street to another. This will reduce rear
end accidents and improve street capacity. Separation of ingress and
egress by medians eliminate delays due to cars using the center of the drive
and blocking other traffic. Use of curbing and lanes perpendicular to the
street for some distance into the parking lot eliminates conflicts between
cars maneuvering within the parking lot and those waiting to e:it. The
driveway section between the returns will continue to be concrete as drive-
ways are now, this will maintain the division between public and private
streets.
The attached sketch is an isometric, schematic view of a typical high volume
commercial driveway described above.

Mokelumne Village Center's request and would like Council direction to
develop criteria and standards for use and construction of what we will
call a I'speclIAcommercial driveway."
