Elec­tri­city BT Line River Dee

S1 S14 S13 Embank­ment Floodplain

Excav­a­tion of scrapes to enhance hab­it­at and flood stor­age. Include vari­able depths cre­at­ing dif­fer­ent hab­it­ats and max­im­ising wild­life benefits.

S9 Cre­ate island fea­tures to increase hab­it­at diversity with­in the scrapes while redu­cing excess cut material.

Remove all bank toe pro­tec­tion along river left bank to remove con­straints to lat­er­al adjust­ment. Install Large Wood Struc­tures (LWS) to enhance nat­ur­al pro­cesses and cre­ate phys­ic­al and hab­it­at diversity in chan­nel. Scrape back embank­ment (strip­ping the turf and reusing it fol­low­ing con­struc­tion) and infill area of low ground behind embank­ment and/​or cre­ation of raised areas of flood­plain, using spoil gen­er­ated from embank­ment remov­al and scrape cre­ation. Retain a sec­tion of exist­ing embank­ment to avoid any impact on exist­ing over­head powerline.
