New threat to Welsh Harp - time to act quickly

The view today from the west bank of the Welsh Harp

The view in the future if the development goes ahead

Four years  ago a united campaign of local political activists and environmentalists saw off proposals for housing developments in both Barnet and Brent areas of Brent Reservoir, popularly known as the Welsh Harp.

Those proposals are dwarfed by the enormous West Hendon development proposed by Barratts which is soon to be considered by Barnet Council.


The development is adjacent to an SSSI (site of Special Scientific Interest) on the Welsh Harp which is home to nesting birds and used by over-wintering birds.  It draws visitors from all over London and beyond. The footpath is well used by many Brent residents who start their walk at the Birchen Grove end of the Welsh Harp.

The development will include tower blocks of up to 26 storeys high - double the height of the one in the photograph.The existing 597 homes will be demolished and replaced by 2,000 houses and flats including 4 tower blocks. There are proposals to build footbridges over the Silk Stream and beside Cool Oak Bridge which are likely to cause water pollution during construction. The area is already one designated as having poor air quality and the development is likely to increase traffic in the area.

Barratts have already built a 12 storey block next to Cool Oak Bridge which gives an indication of the overbearing nature of such blocks and the extent to which they rise above tree height. The new blocks will be twice as high.


There is some confusion about the date by which letters have to be received by Barnet Planning Officers, the safest assumption is that the deadline is April 30th. The Planning Reference is H/01054/13 and the Barnet Planing contactsis: Thomas.Wyld@barnet.gov.uk

I reproduce below a submission on the development that sums up the issues very well:

• There will be a major increase in disturbance of the wildfowl refuge both during construction and when occupied, both due to the excessive height of the buildings and the tripling of the number of occupants
• The developers would like to remove tree screening to open up sight lines. This will make matters worse and increase disturbance. We can expect that this will have a major impact on roosting and nesting birds. The existing tree buffer hides all but the single 15 storey tower that currently exists and in addition to increased disturbance any reduction in the tree cover will have a major and detrimental landscape effect when viewed from the bridge or the footpath to the west of the north reservoir. The tree screen needs to be effectively managed and maintained.
• There will be a large increase in the amount of night-time light pollution in what is currently a dark area. This will affect birds and mammals such as bats. External night-time lighting of the towers must be kept to a minimum. Brightly lit towers have been shown to have a detrimental effect on night flying and migrating birds
• The extreme height of the tower blocks will interfere with flight lines for birds trying to get away from sailing disturbance on the main reservoir. There could also be an increased risk of bird strikes made worse by the large number of high level glass windows.
•  A proposed bridge and circular route crossing the river further upstream will disturb and damage the wet woodland where shy woodland birds such as woodpeckers, owls and warblers breed. This woodland forms part of the SSSI buffer and Local Nature Reserve.
• This proposed bridge will also disturb scarce breeding wildfowl such as Gadwall, Pochard and others which breed in the pools and reed-beds at the end of the reservoir next to the woodland.
• The proposed location of the towers next to the SSSI boundary appears to be mainly for commercial and marketing reasons and has little regard for the nature reserve. They should be lower and further back.
• Due to the huge increase in occupancy of the estate there will be many more people visiting the lake and therefore greatly increasing the disturbance. The planned occupancy level greatly exceeds the level proposed for the site by the GLA.
• The provision of car parking, schools and health centres appears inadequate for the level of occupancy. This will put great strain on local infrastructure, facilities and roads.
• The two reservoirs have an important secondary function as a flood buffer. The huge increase in the local built footprint and areas covered by concrete will have an adverse effect on the carrying capacity in times of heavy rain. Flood events seem to be on the increase at the site from my own observations over a period of 30 years.
• The SSSI boundary with York Park has long been a dumping ground for domestic appliances and waste. The huge increase in occupancy will clearly make this much worse.
