HOLDERNESS FLOODS
OF 25-26 JUNE
2007
My family were badly affected by the floods
of 25-26 June 2007. They and others so affected have asked me
to send this to you.
Findings following consultations with residents,
farmers and authorities:
Evidence of the loss of drain capacity
due to build up of silt and debris.
Allegations that dredged material
from Burstwick drain was found contaminated with toxic material
leading to excessive disposal costs. Drains not cleared since.
Habitat protection schemes are blamed
for mud flat build up at Hedon Haven and Stone Creek. Even though
legislation (Conservation Regs 1994) have provision to allow this.
Claims that the use of mechanical
means to clear outlets to the estuary is prevented to avoid mud
disturbance. English Nature say there is no widespread use of
"management agreements" (as in Conserv' Regs 1994) for
areas bordering SSSIs etc. When put to EA manager Peter Holmes
he agreed it is budget issues affecting maintenance activity.
Humber dredgers now "recycle"
mud under conservancy regulations.
EA blamed for lack of maintenance
on key facilities such as sluices or cloughs, the EA's own evidence
>1 m of debris/silt on sills inhibiting flows to the estuary.
Doors do not fully shut allowing sea water into land drains and
do not fully open to release properly at low tides. Fresh water
or landward side barrier doors are not operated as they had been
years ago to hold water back and to be released suddenly to flush
sluice/clough sills clear.
No adequate flood risk management
for Holderness.
The plan needs to address three risk
cases:
Rising sea levels and tidal
surges.
Sudden high influx of water
from tributaries (45% of England drained to Humber estuary) into
a silt clogged estuary.
Changes in weather patterns
leading to "monsoon" conditions in localised areas of
Holderness.
There is no routine maintenance plan
and no provision for exceptional contingency, even given it is
a high level document.
Keyingham level drain not referred
to, it receives Skeckling drain this drain was a significant contributor
to Burstwick flooding.
Cash damages in the CFMP way off!
Table 3.14 of page 113 of EA's Hull and Coastal Streams Flood
Management Plan are grossly under estimated. The events of 25-26
June much worse than figures given for a 1% AEP! These then affect
cost effectiveness appraisals of any proposed mitigating actions.
There should be use areas of farm
land as flood relieflocal farmers are in favour of these
measures.
Controls on housing developments
are poor.
Examination of one such location
showed NRA recommendations do not appear to have been considered,
they were:
Surface water drainage
cannot go into a system already at maximum capacity (Skeckling
drain).
Therefore this must go
to agricultural run off at a min of 1.4m/sec/hectare.
In this case development
base level should be lifted to the level of a previous development
(approx 2 m)this would have left it away from the effects
of the run off recommendation.
Residents believe the authorities
were slow to respond to the developing emergency.
Residents in particularly high risk
locations not aware of how serious the risk was to them.
When under severe pressure people
turn to most trusted agencies of Police and Fire Brigade, but
these were over stretched.
ERC emergency control not set up
until 1.30 pm Wednesday 27 June?
Sandbag distribution was too lateflooding
already happened.
Representatives sent to talk with
residents appeared too defensive and not "engaged" enough.
