Project summary

Edit project overview to modify the project summary.


The overall objective would be to restore the river channel throughout the park for the 85m length. Due to constraints set by DLR, this may mean leaving one river wall in place and up to half of the bed, however solutions will be available to soften both banks and generate a natural low flow channel. This is likely to be partially funded by the Seager Distillery section 106 agreement, however further funding will be required to complete the whole section of river. This site was cleared and developed into a public park, leaving an 8m boundary to the river for future river restoration works. The channel has a uniform concrete bed and banks and is semi-tidal. It is very shallow during low flow/low tide and could cause a barrier to fish migration. It is devoid of habitat. Start date governed by planning agreement (S106 Seager)
