Project summary

Edit project overview to modify the project summary.


To create space for water, improve biodiversity and habitat, bring the river into the park to make it an accessible feature and improve water quality. Local park with river running north to south along its boundary. Fenced off from the park and and housing, inaccessible and prone to fly tipping. The water quality is poor due to misconnected waste water. There is no/few habitat or aquatic waterborne fauna.
