Environmental Impact of Parking Stall Striping

[Ethan]

While reviewing a preliminary site plan, I came across a few potentially redundant callouts. We will be repaving an entire parking lot, but there are callouts that state: "(E) Striping - To Be Removed".

Does the striping really need to be removed before the existing pavement gets demolished? It seems like extra work.
Is there an environmental reason why the demolished asphalt has to be clean of any paint?

Welcome


Does it mean the same striping will not be there, when redone???

But than again you are talking moon beam land

 

[Ethan]

When we repave, we will also repaint the parking stalls (some will not change, but others will).
Regardless, does the existing paint need to be removed prior to demolition? Or is it acceptable to just demo the asphalt with the paint still on it?

We have a requirement to test for asbestos and lead before proceeding with demolition of a building, and abate if found. I presume you should test for lead in the paint before proceeding; however, that requirement came into effect in 1978 so I can't see how parking lot paint could survive for 39 years.

There are some Californians on the forum.

Give them a day or two to reply.

You can do an anyomous call to the city this project is in and ask the question

I do not require striping be removed prior to removing the paving. But I do require storm water filtering or low impact development procedures when replacing the pavement.

Not sure how you could remove and recover the removed material??

CDA, there are in fact machines that can remove, regrind and repave with the same material. This of course is based on economy of scale and the condition of the subbase.
As was noted, depending on the age of the lot you may or may not have water based striping paint. If oil based it would/could be encapsulated during the above reprocessing.
Removed asphalt can also be reprocessed for use on other sites.

All paint applied before 1978 must be tested for lead, it it tests positive it must be abated by someone certified, I use the same state licensed abatement company I use for asbestos abatement.

In demolishing a building, a licensed abatement company must come in and abate the lead and asbestos prior to demolition to keep the lead and asbestos out of the landfill, I would assume the same applies to parking lots.

I have seen that before, just wondering how and how much trouble to just remove the stripe and a little asphalt only

Asphalt pavement (AP) Contains lead.
Recycled asphalt pavement (RAP) as road base material also Contains lead. Adding the asphalt "encapsulated paint" would not add significat levels of lead.
EPA allows for encapsulation for both lead and asbestos.
It would be different if the striping were to be sandblasted
