KEEPING UP APPEARANCES
A cursory look at the rationale driving
watercourse management
in Derby.

Why Bother
• Heritage – Should it worry us
• Achievement – Will anyone notice
• Sustainability – Does it make a difference

Detail of Area Considered

What can be done
• Do Nothing –
Works already done,
minimise further
disturbance of nature,
allow natural ecology to
find balance.
• Do minimum –
Prevent flooding, do not
allow situation to worsen
• Do something –
Carry out regular
assessment, remove
degradation, provide
regular maintenance,
restore and improve as
deterioration takes place.

Who can do it • Riparian Owner • Incentives needed - Why should they other than personal
satisfaction
• Finance – Regularly limited by funds available
• Economics – Large schemes on private land crippling for
individual
• Time – Insufficient available to dedicate to large operation
• Energy – Sheer effort required can be beyond most
individuals
• Skill – Protected Species may be involved

Induced flood potential through lack of understanding

Who Else could do it
• Ecological Groups (Do Gooders) • Unable to be there at correct or required time
• Cost limitations with finances frequently limited
• Skills – often marginal or not across board to give needed
input
• H&S Considerations – Often unable to be met through
group structure
• Specialisation – Often required to take further advice

How About Public Body
• Incentive – Public Duty and practical duties
• Finances – Public purse & grant allowance where available
• Time – Not restricted to part time or availability of
disparate groups
• Skills – Trained specialist staff used to carrying out similar
functions
• H&S requirements – Formal contracts using known &
approved formulae with compliance contractors
• Specialisation – Availability to divide work into specific
disciplines to suit requirements

How Do We Do It
• Think Big – Whole problem not just part of it
• Think CAMP – Consider whole catchment not
solely area directly affected
• Think Long – Approach scheme with a view to
long term benefit (125 years design life for
structures)
• Think Others – Remember that actions taken now
may not affect environment for some years
