Wadley Road / Esther Road / King’s Passage
Flood Risk Management Scheme
Following the extreme flooding in Waltham Forest during summer 2021, we have been developing a scheme that aims to reduce the risk of flooding in your local area.
As Wadley Road, Esther Road and King’s Passage were some of the most affected areas in the borough, the Council is prioritising these areas for further investment in highway improvement measures aimed at reducing instances of local flooding, by relieving pressure on Thames Water infrastructure (drainage systems) to minimise flood risk to residential properties. The schemes also aim to improve and support the local drainage system and biodiversity by introducing Sustainable Urban Drainage Systems (SuDS) where feasible.
The initial concept design for the area includes the elements below:
· Permeable Surfacing
A permeable road and pavement is proposed to allow rainwater and overland flows to infiltrate through the carriageway surfacing and into the voided stone fill sub-base layer below, which provides surface water attenuation. These stored volumes of surface water are discharged back into the Thames Water sewer system at a controlled rate over a period of time as capacity becomes available in the sewer network after the storm event has passed and the surcharging in the sewer network subsides.
These SuDS features provide an opportunity for infiltration and the voided stone fill layer provides attenuation for surface water flows during rainfall and storm events. This stored rainwater is discharged into the sewer network at a controlled rate when capacity becomes available once surcharging in the sewer network subsides after the storm event has passed. Raingardens also provide enhanced amenity, with an improved ecological habitat with enhanced biodiversity and a generally improved appearance to the area.
In addition, Thames Water and Waltham Forest Council have jointly funded a local representative for a minimum of one year to join the National Flood Forum, which is an independent charity that supports individuals and communities at risk of flooding. The representative will assist in developing a Community Flood Plan as well as organising self-sustainable community-based support networks in the event of an emergency.
We will be arranging a scheme drop-in session, where you can come and view the concept design plans and talk to council officers.
Please see drop-in session details below:
Wednesday 25 May 2022 between 5pm and 7pm
at Elim Pentecostal Church, Hainault Rd, Leytonstone, London, E11 1EL
We may also have a representative from the National Flood Forum attending the drop-in session to answer any queries.
