just found the full report, takes a long time to download but just read this critical bit:

"Second, other than for some limited areas of public burial, most areas of Camberwell New do not become ‘old’ enough for re-use until at least 2045, by which time all the
short and medium term options will have been exhausted. Some of the shortfall in capacity might be made up by taking up a portion of Honor Oak Park, (1/3rd) whilst retaining the football pitches and substantively enhancing the remainder of the Park.
Recognising that this is likely to be unpopular and, at this point in time, not an option preferred by the Council the Strategy considers it essential that the authority should also conduct a review of Nunhead Cemetery to ascertain whether, mindful of the particular sensitivities and status of that cemetery, there is any scope for limited reclamation/re-use in conjunction with restoration. In addition, working in partnership with other London authorities, the council should seek to secure alternative burial space, (potentially also including natural burial space) by way of an additionallandholding."

So at first glance, it seems that the Council will only move on the Rec if all their other stratgies fall short in 27 years! Is that reason for optimism?!
