Project summary

Edit project overview to modify the project summary.


Deculverting through the park. Scope for accompanying lake enhancement/ fisheries project. Loxford Water is heavily urbanised, degraded and a in a concrete culvert for the most of its length. Through the park there is space available for re-naturalising the river. At the moment it is fully concreted bed and banks or rip-rap further downstream adjacent to the lakes.

Monitoring surveys and results

This case study hasn’t got any Monitoring survey and results, you can add some by editing the project overview.
