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.
