Dear resident:
As a part of the City of Carlsbad’s ongoing
program to maintain its streets, your street will be
slurry sealed over the existing roadway surface.
This construction will require the closing of your
street to through traffic for one day. Your street,
from XYZ St. to DEF Ave. will be closed to
through traffic and resurfaced on:
MON. TUE. WED. THU. FRI.
DATE: _XX / XX / XX______________
from 7:00A.M. to 5:00 P.M.
If you don’t plan to leave your home by 7:00 A.M.
on the above date please park your car on an
adjacent street in your neighborhood that will not
be resurfaced. Streets scheduled for resurfacing
can be determined by calling either the
Contractor or the C ity of Carlsbad’s Project
Inspector. When walking to and from your car,
remember not to walk on the newly overlaid street
or you will have black residue on the bottom of
your shoes. Please do not drive, walk on, walk
pets, play, or skate on the newly overlaid asphalt.
Also, please refrain from watering your lawns,
washing cars, etc., approximately 6-8 hours after
the asphalt is laid as running water will cause
damage to the new surface.
ABC is the Contractor that will be performing the
resurfacing w ork for the city and you may call
them at the above phone number if you have any
questions regarding the project. Resurfacing of
your street will not occur on the day your trash is

please call and inform the Contractor of the date.
If you have any concerns which cannot be
addressed by the Contractor, you may call the
City’s Project Inspector @ (xxx) xxx-xxxx.
Thank you for your cooperation as we work to
make a better City of Carlsbad.
