|Project summary=Ladywell Fields has been transformed from its previously characterless and formless landscape into a diverse, popular and accessible public open space. The creation of a new gravel-bedded river channel through the centre of the park has also brought about significant improvements in biodiversity. Ladywell Fields won the best-new-public-space category at London Planning Awards for its rejuvenated park in Lewisham.

|Project summary=
*Date implemented - 2007
     
 
*Maintenance checks - channel erosion, sedimentation in ponds, vegetation control
 
*Investment (£) 1,404,500
 
*Additional storage (m3) 15,000
 
*Elevation of defences (m) < 2
 
*Risk reduction - impacts modelled
 
|Monitoring surveys and results=*Surveys indicating that the public’s perception of the park in terms of recreational value and safety has improved. Now 78% visitors feel safe (in comparison to 44% before the restoration), and use of the park has increased over 2 and a half times.
 
*survey results indicating a near 100% increase in the number of species present in the park (in particular fishing birds), which are benefiting from the greater range of habitat types now present following the restoration works.
|Lessons learn=Performance/Ecosystem benefits - large increase in flood water storage to maintain 1 in 100 year protection, range of environmental benefits including backwaters, riffles and pools

Project summary

Edit project overview to modify the project summary.


Ladywell Fields has been transformed from its previously characterless and formless landscape into a diverse, popular and accessible public open space. The creation of a new gravel-bedded river channel through the centre of the park has also brought about significant improvements in biodiversity. Ladywell Fields won the best-new-public-space category at London Planning Awards for its rejuvenated park in Lewisham.

  • Aims - natural flood risk management, land use change
  • Other aims and benefits - improving ecology, improving hydromorphological conditions
  • Rainfall (mm) 557
  • Altitude (m) 22
  • Type - Implemented Working with Natural Processes measures
  • Measures Flood storage areas, Reconnect rivers to floodplain
