Brooke Road Flood Risk Management Scheme

Following the serious flooding in Waltham Forest during summer 2021, we have been working with Thames Water, the Department for Education and residents to develop a scheme that will help reduce the risk in flood-prone areas, and help protect local homes, schools and businesses.

As Brooke Road was one of the worst affected places, the Council is prioritising this area for further investment to help tackle the issues caused by heavy rainfall, reduce pressure on Thames Water’s infrastructure (drainage systems), minimise risk to residential properties and St Mary’s C of E School, and enhance biodiversity.

Thanks to funding from Thames Water, the Department for Education and Waltham Forest Council we have developed the following concept plans for the area:

  • Install rain gardens along the carriageway on Brooke Road to manage rainwater run off from hard surfaces after downpours. Rain gardens often involve planting attractive, low maintenance, wildlife-friendly plants which also help boost biodiversity.
  • Install water attenuation and storage cells:
    • under the road surface between St Mary’s C of E School and the junction with Oliver Road
    • under the school yard and on Chestnut Avenue.
    • An attenuation cell is an underground tank which receives water from the surface either through a permeable carriageway surfacing material or drainage slots. This additional storage helps slow the rate of water flowing into Thames Water’s infrastructure (drainage system), relieving pressure during intense periods of rainfall, and preventing drains overflowing and flooding.
  • Permeable carriageway surfacing and road construction along parts of Brooke Road. The new permeable surfacing and road construction used will absorb rainwater and allow it to flow into the underground storage tanks. The new permeable road construction also acts as a temporary additional rainwater storage in its own right, slowing down the speed at which the water enters Thames Water’s infrastructure.
  • St Mary’s C of E School will be supporting our scheme with their ‘SuDS’ (Sustainable Urban Drainage) in Schools’ initiative and is proposing to harvest rainwater by linking the school’s downpipes to rain planters.

In addition, Thames Water and Waltham Forest Council will jointly fund 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.

To view the concept plans and ask Council Officers questions, come along to our Brooke Road Flood Risk Management Scheme Drop-in session on Thursday 16 March 2022, anytime between 5pm and 7pm at the ‘14th Walthamstow Scout Group’, 205a Wood Street, E17 3NU.

We may also have a representative from the National Flood Forum attending the drop-in session to answer any queries.
