Promenade area not safer after redevelopment (8)
I believe the answer is:
seafront
'promenade area' is the definition.
'seafront' can be an answer for 'promenade' (I've seen this before). I am unsure of the 'area' bit.
'not safer after redevelopment' is the wordplay.
'after redevelopment' indicates anagramming the letters.
'not'+'safer'='notsafer'
'notsafer' is an anagram of 'SEAFRONT'.
Can you help me to learn more?
(Other definitions for seafront that I've seen before include "promenade" , "No faster (anag)" , "that's where the waves come in" , "Prom?" .)
