North Cave Catchment Partnership

Partners and benefits
hide
Council
leaf
officer expertise across flooding, drainage, highways, tree planting, more?
leaf
political backing
hide
EA
leaf
catchment-based approach, biodiversity targets
hide
YW
leaf
relationship between foul and surface water
leaf
flood risk + resilience
hide
OHDB
leaf
issue of current role and extent of remit
hide
Landowners
leaf
key partners, with knowledge of land and land-use.
leaf
can partnership make agriculture more resilient to flood and drought? (e.g. reduce erosion, provide irrigation water)
hide
Community
leaf
Take responsibility for matters which over-stretch council resources: monitoring, simple maintenance
leaf
Maintain a common and continuous view of what is needed
leaf
Local knowledge + flood experience
leaf
Act within own property, whether house or landholding
leaf
Property resilience
hide
Monitor weather...
leaf
understand relationship between events (e.g. 7/14 Nov each close to 50mm, 2007 80mm) so understand implications of weather forecasts and warnings
leaf
contribute to understanding of flood events
hide
Education
leaf
University research
leaf
School involvement e.g. monitoring
hide
Wildlife trusts other partnerships
leaf
e.g. “Chalkshire” biodiversity opportunities
hide
Funding
leaf
e.g. weather monitoring, highway / ditch / attenuation works, landowner compensation?, planting grants
hide
Taking a Partnership Approach
leaf
Benefit of combined expertise / action / funding
leaf
Response to flooding should not be ‘one-off’ actions.
leaf
Regular meetings (perhaps every few months, reverting to annual over time).
leaf
Maintain continuity of attention and approach, ensure maintenance is carried out to an agreed regime
hide
Issues
hide
Wider catchment
leaf
37 sq km determines behaviour of and flooding along becks
leaf
Inc Newbald and Hotham
leaf
potential for greatest depth/speed of flood water
leaf
most complicated to resolve
leaf
effects most noted through centre of North Cave, Mires Lane
leaf
Need to consider downstream effects e.g. South Cave / Ellerker
hide
Local catchments
leaf
Smaller areas unconnected with main rivers
leaf
Surface flooding can happen anywhere a flow path coincides with property (e.g. Nordham, Ev Lane, Everthorpe) - only Nordham appears on Surface flooding maps.
leaf
simpler to resolve
hide
affect wider catchment and main rivers
leaf
e.g. Everthorpe Lane > Station Road > Croft > Finkle St > Blanshards Ln > NC Beck > Mires Beck > Ellerker
leaf
e.g. Everthorpe > South Cave (West End)
leaf
Only North Cave Catchment?
hide
Principles
leaf
NOT to 'get water away'!
hide
Catch and detain water where it falls, across all parts of the catchment
leaf
e.g. along Hotham- Drewton- North Cave- Mires- Becks.
leaf
Intercept, detain and direct flow paths
leaf
Create controlled flow paths around groupings of property
leaf
Take opportunities to use existing infrastructure, like ditches, to both expand attenuation capacity and detain water with leaky dams (whether woody or engineered)
leaf
Reduce surface water surcharge to foul sewers
hide
Need to review and document issues like
leaf
drainage at Nordham and Everthorpe
leaf
relief from The Croft to Mires Beck (currently YW pipe)
leaf
low bridge at Froscoles
leaf
link from beck to wetlands - Townend Lane
leaf
effect of impermeable cells of restored water between Mires Lane and South Ings Lane (and consider effect of next stage of quarrying)
hide
Data exchange
leaf
foul / surface water routes
leaf
mapping
hide
Next steps
leaf
Willingness and authority to commit to a partnership
leaf
Terms of partnership, formalities, obligations
leaf
Identify what partners can bring to the partnership (expertise, funding...)
hide
Actions
leaf
convene formal partnership meeting with agencies, landowners, residents
leaf
agree scope and aims
hide
identify priorities based on:
leaf
regularity and severity of flooding
leaf
achievability of mitigation
leaf
cost / funding
leaf
ERYC S19 report and other official / statutory inputs
hide
set timescales for action based on:
leaf
short/long term
leaf
liaison within partnership
leaf
landowner agreements
leaf
funding
leaf
design
leaf
planning / other approvals
leaf
implementation
leaf
publicity / wider engagement
