Great sites for redevelopment according to schemes (10)

I believe the answer is:

strategies

'schemes' is the definition.
('strategy' can be a synonym of 'scheme')

'great sites for redevelopment' is the wordplay.
'for redevelopment' indicates an anagram (letters developed into a new form).
'great'+'sites'='greatsites'
'greatsites' is an anagram of 'STRATEGIES'.

'according to' is the link.

(Another definition for strategies that I've seen is " What planners need".)

I've seen this clue in The Times.
