(Date)

As part of the City of Carlsbad’s ongoing program to maintain our roadways, streets in your neighborhood are scheduled for resurfacing in the coming weeks. The resurfacing work will require traffic control to be put in place in those areas. The work will take place between the hours of 8:30 a.m. and approximately 3:30 p.m., or until the traffic control devices are removed.

Residents located on the streets scheduled for resurfacing will be notified 72 hours in advance of the work. Look for a brightly colored 3 ½” x 8 ½” card attached to your doorknob. You will also notice temporary “no parking” signs on your street with a specific “no parking” date written on it.

PLEASE NOTE: weather conditions and other factors outside our control can sometimes cause work to be rescheduled at the last minute. If this happens, we will notify you as soon as possible of the new date.

To prepare for this road work, we are asking neighbors to help. Here’s how:

• Park your car outside the area of work unless you plan to leave before 8 a.m. the morning the work starts. Watch for “no parking” signs.
• Park your car in your driveway or garage (off the street) if you aren’t going to need it between 8:30 a.m. and 3:30 p.m.
• Avoid walking, bik ing and skate boarding on new roads until construction signs are removed.
• Please keep kids and pets off the new roadway on the day of the resurfacing. • Do not walk on the newly resurfaced street or you may get black residue on the bottom of your shoes. The residue may damage or mark surfaces and be very difficult to remove. • Please try to keep the work area and new road dry until construction signs are removed.

Monitor sprinklers, hoses and other water sources around your home. • Please note that mail could be delayed on the day of the resurfacing if your postal carrier cannot reach your mailbox.
• Work will be coordinated with trash pick-up.
• If you have a special concern or need reasonable accommodations, please call the City of Carlsbad at 760-602-2780.

(Contractor Name) will be performing the resurfacing work for the city. You may call a contractor representative at (XXX) XXX -XXXX for more information about the project and to answer questions.

Dear resident:

As a part of the City of Carlsbad’s ongoing program to
maintain its streets, your street will be resurfaced with asphalt concrete 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: / /
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 City 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 you r lawns, washing cars, etc., approximately 6 -8 hours after the asphalt is laid as running water will cause damage to the new surface.

You may call the Contractor that will be performing the resurfacing work for the city at the above phone number if you have any questions. Resurfacing of your street will not occur on the day your trash is collected. Mail delivery may be delayed if the postman cannot reach the mailbox
