Personally I appreciate people leaving things like this out so they can find new homes, but if you don’t like seeing it there, you can often get useful (or even apparently useless!) items removed from the streets more quickly by posting them on Craigslist.

They have an active free stuff page for people to list items being given away or discarded, where many people post about items left out on the street:

https://sfbay.craigslist.org/search/zip?query=free%20stuff#search=1~gallery

It costs nothing to post a street find, just go to https://www.Craigslist.org, click on "create a posting", and choose "free" under the "for sale" category.

It's a better place than this to find people willing and happy to take something off the street and reuse it – probably faster than government officials relying on public resources will get around to removal too.

Best of all, the items you list may find a better home than just getting sent to the landfill.
