Halliwick Recreation Ground - Sustainable Urban Drainage Scheme (SuDS) consultation

Share on Facebook Share on Twitter Share on Linkedin Email this link

Background

The council is the Lead Local Flood Authority (LLFA) for London Borough of Barnet as stipulated under Flood and Water Management Act 2010. As an LLFA this means we are responsible for managing local flood risks from surface water, groundwater, and ordinary watercourses across the borough.

Barnet’s Local Flood Risk Management Strategy has identified 33 Critical Drainage Areas (CDAs) which are at the highest risk of surface water flooding. The top ten priority CDA’s, including Muswell Hill (CDA 014), are part of our priority flood risk management program that has been produced as part of our Local Flood Risk Management Strategy.

This consultation is for the proposed flood alleviation scheme (within Muswell Hill CDA) at Halliwick Recreational Ground (N10) in Barnet. The scheme proposes to build a new flood storage detention basin in the north -eastern corner of the Halliwick Recreational ground which will store storm water during heavy rain, reducing the risk of flooding to nearby properties and highways.

Benefits of the proposed scheme

The proposed scheme will be the first sustainable urban drainage scheme in the borough. In addition to providing flood mitigation benefits, the scheme will provide environmental, amenity benefits for the local residents and biodiversity and habitat enhancements. The flood storage basin will also provide water quality benefits by treating the storm water runoff from the highways.


Scheme details and how the scheme will look

The scheme will divert the rainwater from Albion Avenue (N10) into a shallow drainage channel along the existing footpath in the recreation ground and then store it in a basin in the north-eastern corner of the Halliwick Recreational ground. The scheme will be carefully designed to reduce the flood risk to the nearby properties and highways. You can view the images here.


What we are consulting on

The scheme is now being moved into Detailed Design and Construction stage and we want to hear your views on our proposals, so that we can gather your feedback at an early stage, before the detailed designs are finalised. We are very interested to hear from local residents specially along The Vale, Albion Avenue, George Crescent and other adjacent streets about their past flooding experiences.


How to have your say:

Attend an engagement event in the Recreational ground.

An engagement event on the proposed scheme has been organised for 19 June in the Halliwick Recreation Ground, where we will be happy to share more information on the scheme and capture any initial feedback from local residents.

The event will also be used to highlight the benefits are of such schemes and help raise awareness of the flood risk and impacts of climate change within the local community.

Regular engagement events will then be organised in the Recreation Ground throughout the summer and autumn and the dates will be published on this page. We will keep residents updated on the progress of the scheme.
