That'll be something taxpayers will have a hawkseye on since taxpayers' money are heavily invested into the Olympic Village. The justification at the time that it was invested was for plans to turn over the units for social housing after the events and that there were proposed plans to build up social housing in that area. There may be a portion sold off to private buyers at market rate {for an immediate ROI) and a portion on a shared ownership which is how most new-built properties under social housing i.e. "affordable" is sold. Market rate over here is £250,000 on average now. The rest, I presume, would fall within the norm i.e. controlled rents. The beneficiaries of the housing units will be very lucky as most of the associated facilities to the Village will remain.

A further hawkseye on the impact of the events to be held in my town.

"GREENWICH Park will not be fully restored to its current state after the Olympics until 2015, the planning application documents, published on the council’s website on Tuesday, show.

Areas of the park will be closed off from February or March 2010, meaning that the park has less than four months of full public access left. The total duration of the Olympic-related works and closures in the Park will be five years. The total duration of the events themselves is two weeks.

The length of the work period, far in excess of expectations, is one of a number of very unpleasant shocks from the planning application documents. The principal document, the Environmental Statement volume 1 (ES), is downloadable in two parts from this document list

(it is about three-quarters of the way down the list of documents). References which follow are to ES paragraph numbers, except where indicated.

Lorry and vehicle movements

Construction and removal of the main 23,00-seat showjumping arena will create an estimated 6,420 lorry movements to the park - an average of 43 to 58 per day .(ES 3.4.17). This phase will close large parts of the park for a total of eight months in 2012, from April to November inclusive (ES 3.2).

Other items of plant in the park will include 160-tonne mobile cranes, 5 tonne mini-excavators, bulldozers and JCBs (ES 3.4.23).

The events themselves will create 35,960 vehicle movements by competitors, officials and media to the park, an average of 625 a day. (ES 3.4.32). The park will be almost completely closed for four weeks (ES 3.3.7) and largely closed for longer.

Heritage impact (archaeology, historic buildings, etc.)

The overall permanent impact on the park’s heritage features is assessed as “likely to be neutral to slightly adverse” and the ES admits that some heritage features could suffer permanent “loss or partial loss.” (ES introduction, page 10).

Most features, it is claimed, will be protected by mitigation (protective structures and the like). But “as a last resort,” some heritage features will be “preserv[ed] by record,” ie permanently destroyed, but only after pictures and records have been made of them. (ES introduction, page 10).

A set of ornate gates into the park will be removed to allow vehicle access, although it is promised that they will be replaced afterwards.

Visual impact and trees

The park will be surrounded by a 9-foot-high metal security fence, with spotlights every 80 feet and CCTV cameras on 16-foot poles every 250 feet. There will be a similar, inner fence cordoning off other areas. (ES 3.2.32-3.)

The ground in the open area in front of the Maritime Museum, which currently slopes slightly, will be made level, with topsoil potentially needing to be stripped to a depth of 1.3 feet. “Retaining structures” may have to be installed in the soil in this area. (ES 3.2.2-9.)

Seventy-two trees will be pruned to allow a 11-foot clearance for horses to pass underneath, including a “small number” which will suffer “removal of branches to the main stem.” The majority of pruning would be to branches of 25mm or less,
although a number would be up to but not more than 50mm. (ES 12.6.9).

There will be temporary power plants, water and fuel tank compounds (ES 3.2.52-5). Temprary ducts will be dug across the park to divert some existing gas, water and sewage mains pipes which currently pass under areas needed for the competition (ES 3.2.61).

“On balance, the overall magnitude of change is considered to be
medium adverse resulting in a moderate adverse effect.” (ES 12.6.14)"

Just a few of the reasons against holding the events at the Royal Park. The residents firmly hold that the damage to the Royal Park is disproportionate to the benefits.
