The following is being circulated as a flyer to residents of Earl and Duke Streets and Bullstake Close. Links are being emailed to our supporters.

Update from the Oxford Flood Alliance (OFA) on Progress in Reducing the Risk of Flooding of Earl and Duke Streets and Bullstake Close; July 2010

It is 3 years since the severe floods of July 2007, so it seems a good moment to report on progress made since then, but also to highlight a further project that requires the most urgent and determined action. OFA has worked hard, since November 2007, to make sure things have been done and we continue to do so.

How these streets flood

Earl and Duke Streets flood by a combination of water coming up through the ground, water coming up through the drains and water which arrives over the surface. Bullstake Close floods by surface water.

What has been done

Bullstake Close:
Oxford City Council built a wall around part of Bullstake Close to protect it from surface water arriving from north of the Botley Road. DONE, 2009

Earl and Duke Streets:
the Bullstake Close barrier will hold back flood water until it is overtopped. DONE, 2009

Thames Water and Oxford City have installed special valves which, when flooding threatens, can be closed to isolate the drains in Earl and Duke Streets from other local drains, taking the pressure off them. DONE, 2009

there are permanent pumps in Earl Street, installed by Oxford City (?) to pump accumulating floodwater away into the floodplain to the south. DONE, 2004

the gullies in the street have been altered so that that all now feed into the pumps, so enabling the pumps to work more effectively. DONE, 2010

a culvert has been installed by Oxfordshire County Council at the end of Duke Street and out into the floodplain to the south. This is to provide a route out for water running down Earl Street from the Botley Road. To streamline the flow of this water the pavement has been rounded off where Earl Street connects via an alley into Duke Street. DONE, 2009

a road and pavement hump built by Oxfordshire County Council across the Botley Road end of Earl Street to stop floodwater flowing down the street (until it is overtopped). PLANNED FOR 2010

a barrier across the path leading into the southern end of Duke Street to prevent water flowing into the street from Bulstake Stream which it has done in the past. UNDER CONSIDERATION

the City Council has suggested that residents at the southern end of the east side of Duke Street might like to consider property level defences for their houses. Property level defences means floodgates for doors and sealing off airbricks. If everyone got together and did this, this would make a barrier to stop water flowing into and through these houses from Bulstake Stream. This would directly protect the individual houses and, indirectly, their neighbours. It is possible that grants may be available to help with the costs of this, though current cuts mean this is uncertain. RESIDENTS WILL DECIDE WHETHER THEY ARE INTERESTED.

last but not least, providing an alternative route for floodwater in the Botley Road to get away downstream to the south. In the past it has flowed down Earl Street like a river. The alternative route proposed is down Lamarsh RoadUNDER ACTIVE AND URGENT CONSIDERATION.
