Ting is using a ground penetrating radar machine to check for any underground conflicts with the planned work before it begins work in the street. The GPR machine, as it is called, is about the size a lawnmower, doesn’t make any noise, and its work is quickly completed as it simply needs to be walked up and down the street, directly where cars are typically parked. For this reason, Ting needs to post for no parking. However, it doesn't take long for the GPR machine to pass, and that part of the work can easily be missed by those expecting large construction equipment. To allow the GPR work, the no-parking period may last 1-2 days because Ting isn't certain of when the GPR machine will be on any particular street segment. However, after completing the GPR pass, Ting is removing the no parking signs, to allow cars to resume parking. Sometimes, Ting may not remove the orange cones, but may simply update the no-parking signs to indicate the future no-parking dates for other parts of the project.
The other frequent explanation for why a street appears to be posted for no parking but no work is being done is that large areas may be posted with orange cones for no parking, but different sub-areas are posted with different dates for different ranges of days.
There are instances where Ting has scheduled work and has had to reschedule for one reason or another. If you have questions about why your specific block was posted for no parking without seeing any work being done, please contact Jason Dowty at Ting at firstname.lastname@example.org or call (424) 392-6572. If Jason is unable to address your question or concern, then please contact the Culver City Public Works Engineering Division at (310) 253-5600.
