Fedi-brain-hive, I need you once again.

Is there an #English #word that means "to make permanent?" Essentially, I need the word "permanentize" to exist, but evidently it does not. Surely another word exists in its stead?

Please #help! This problem has been vexing me for over three years (since I began tracking the way cities changed their street space during the pandemic and whether or not those changes were permanentized).

I'm so tired of writing "were made permanent."
