Email consultation:

We are seeking your views on the Council’s proposal to introduce a sustainable drainage system (SuDS) on the southern end of Camley Street between the rail bridge and the junction with Goods Way. SuDS help to reduce flood risk, improve water quality and take pressure off the sewer network. In addition to managing surface water runoff, SuDS can contribute towards building the place function of streets, increasing biodiversity and better water and air quality.
 
We have been exploring options for incorporating SuDS on the public highway throughout the London Borough of Camden, and as part of this propose to establish this pilot project on Camley Street. If implemented, it is hoped this scheme will set a precedent for other interventions in the borough, and increase SuDS awareness and knowledge within Camden.
 
The Council’s flood risk modelling indicates that Camley Street is an area of elevated flood risk, particularly the southern end near the junction with Goods Way. In response to this, the Council is proposing to introduce SuDS rain gardens on Camley Street. Rain gardens are planted areas that allow rainwater to be collected, stored and filtered into the groundwater system. The proposed rain gardens on Camley Street will include the following features:
 
·         a 2m wide linear bioretention raingarden along the western kerbline – a planted feature with freely infiltrating soils and storage layers beneath that will collect all the rainwater  from the carriageway and western footway.

·         the width of the carriageway will be reduced to 6m and the footway on the western side of the road reduced to a width of 2m, over a total gross length of approximately 180m. This is to allow for the 2m wide rain gardens. The road markings and formal parking provision (three disabled bays) on Camley Street will not change.

·         existing vehicle access points on the western side of the footway will be retained, and pedestrian crossing points will be designed in at appropriate intervals.

·         the SuDS system will be designed to deal with a 1 in 30 year flood event.
 
It is our view that introducing SuDS on Camley Street will improve the streetscape and experience of Camley Street in the following ways:
·         reduced flood risk
·         reduced reliance on the sewer network
·         general visual enhancement
·         increased separation of vehicles and pedestrians
·         air quality improvements for pedestrians
·         biodiversity enhancement
·         additional planting and greater contact with nature
 
The scheme is being funded through Thames Water, as part of the London Strategic SuDS Pilot Study, and funding from Section 106 contributions.
