Counters Creek was originally a stream that flowed from Kensal Green to Chelsea Creek. It played an important role in natural drainage in the area but over the years it's been filled in, covered and diverted and only small sections remain visible.
The Counters Creek Flood Alleviation Scheme (CCFAS) was developed following widespread basement flooding caused by intense rainfalls in the Royal Borough of Kensington and Chelsea and the London Borough of Hammersmith and Fulham.
The flood alleviation project is intended to provide flood protection and was programmed to be completed by March 2020.
We've been constructing flood protection measures for many basement properties affected by flooding since 2007. These measures include:
These measures have helped to reduce the number of reported flooding incidents significantly. Further intense rainfalls experienced in recent years indicate that these measures have been effective in the reduction of flooding risk to basement properties.
We've therefore decided to continue with this approach - namely the construction of local schemes and installation of FLIPs - in order to protect the remaining basement properties with reported flooding.
In addition, we're working in partnership with the London of Hammersmith and Fulham to implement a number of Sustainable Urban Drainage Systems, also known as SuDS, to reduce peak flows into the sewer network.
In summary, the measures included in the Counters Creek Flood Alleviation Scheme are:
FLIPs are local protection devices in the form of a small pump, which are fitted in the basement, light well or road to protect properties from flooding. Since 2007, we have installed over 900 local protection devices to individual or adjoining properties and from 2017 to 2020 are installing around another 400 of these devices.
We're also constructing up to seven local schemes to increase the sewer capacity and provide flood protection for multiple properties. The construction of three of these schemes started in February 2019 and the rest are programmed to continue into early 2020.
The local schemes are being constructed by Barhale Ltd and the start dates are below:
We will be contacting residents and businesses in the immediate areas of these schemes and will be liaising closely with the local authorities whilst work is being carried out.
Sustainable Urban Drainage Systems, or SuDS, are an important method of managing flows in the catchment, which is a key part of reducing the risk of flooding in the long term. Between 2010 and 2015, we worked with the London Boroughs of Hammersmith and Fulham, and the Royal Borough of Kensington and Chelsea, to implement three sustainable drainage systems at Melina Road, Mendora Road, and Arundel Gardens. These were trials to assess the performance of different types of drainage systems in reducing flows into the sewer system.
Based on the results of the trials, we're now working with the boroughs again to implement a further five drainage systems in the catchment. These will include replacing the road surface with porous materials and allowing rainwater to filter through into the structures underneath the road where it's stored and then passed forward to the sewer system at a slower rate.
The proposed streets for SuDS are:
This approach to flood alleviation has been chosen following extensive investigations and consultation with the local community between 2010 and 2015. One of the many options tabled was to construct a storm relief sewer tunnel. We moved away from this option as:
