Parish flood defences
In 2017, we contributed 50% towards the cost of Flood Doors installed at two properties along St Whites Road to protect the properties from flooding from The Cinderford Brook.
In 2019, we made drainage improvement works to alleviate flooding along the ordinary watercourse on the Milkwall Cycle Track, Coleford. A replacement trash screen was constructed to reduce the degree of blockage and improve the conveyance of water, and new steps were installed to improve access for maintenance.
In order to reduce the frequency of flooding to a property at high flows, we installed a Stop Log Flow Control to improve the conveyance of water away from the property and enable the watercourse to be used to its full capacity.
We plan to undertake drainage improvement works in 2020, to alleviate flooding of residential properties from an ordinary watercourse off Church Road, Longhope. A replacement trash screen will be constructed to reduce the degree of blockage and improve the conveyance of water. Access will also be improved for ease of maintenance.
Lakeside Ave (upstream attenuation)
In 2015, a penstock was installed by Forest of Dean District Council (FODDC) upstream of the A48, to maximise the capacity of the channel and attenuate runoff, slowing the flow of water towards the downstream residential area (Lakeside Ave).
At the request of FODDC, further in-channel attenuation was installed by the land owner in Spring 2017. This consisted of two earth bunds to maximise the capacity of the channel and further slow the flow of water towards the downstream residential area (Lakeside Ave).
Lakeside Ave (replacement headwall and trash screen)
In Summer 2017 we improved the evacuation of water at the culvert entrance upstream of Lakeside Ave. The original trash screen had the potential to block and during high rainfall events in Summer 2007 and Winter 2013 and 2014, resulted in significant flooding along Lakeside Avenue.
The scheme involved extending both culverts, 12m upstream onto Forest of Dean District Council land and installing a new brick and block headwall with main culvert and overflow “on face”. An improved trash screen design was installed, with vertical flat bars to reduce the potential for blockage.
A flood alleviation scheme was undertaken in 2018 to reduce the frequency of flooding to properties in Newent Town Centre and a number of residential properties adjacent to the Peacocks Brook. The main aspect of this flood alleviation work was the construction of a 50m long, 1.5m high earth bund, to create a significant storage area upstream of the residential area.
