Rottingdean High Street air quality trial scheme

On 25 October 2019 we started an experimental trial aimed at addressing poor air quality in some parts of Rottingdean Village caused by vehicle emissions.

Rottingdean has been the subject of an Air Quality Management Area (AQMA) since 2013 as levels of nitrogen dioxide have exceeded the statutory limit set by the government. Road transport is the main source of the emissions.

The proposals seek to address air quality issues in the section of the High Street south of Park Road where there is close proximity of residential frontages to the kerb. In this area, nitrogen dioxide is in excess of EU and UK regulation and therefore presents the greatest hazard to health for residents.

Our proposals

Rottingdean Parish Council and Brighton & Hove City Council formed a joint action group in response to serious public concerns about this issue.

The project group, including ward and parish councillors, commissioned traffic modelling to consider various options and are now proposing to trial an experimental traffic order on a temporary basis. The trial will consist of three physical measures: 

  • a temporary chicane outside 80-82 High Street (north of Park Road/south of the existing zebra crossing) with a give way to the north giving priority to northbound traffic
  • a no stopping (yellow hatched) box on the southbound lane from southern building line of Dene’s Mews (northern wall of 66 High Street) to the southern boundary of 29 High Street
  • a ban on right turns out of West Street

Benefits of our proposals

The chicane is intended to encourage a free flow in the narrowest bit of the High Street where the air quality is worst. The yellow hatched box on the southbound lane is intended to prevent vehicles from waiting in the same area. The ban on right turns out of West Street is intended to prevent vehicles blocking the northbound lane.

Additional air quality monitoring technology will be installed to establish the success of the scheme in improving air quality in the area.

Working with residents and businesses during the trial

The trial will be in place for up to 18 months and will be subject to monitoring for the first 12 months.

We invite residents and businesses to share their views and objections during the first 6 months of the trial.

Project update: 31 October 2019

The planter has been moved 1 metre to the north to improve the safety of left turns out of Park Road. Planting will take place in mid-November and ‘Rottingdean in Bloom’ will maintain the plants during the trial. Council staff continue to work with retailers on the High Street and West Street to resolve issues around lorry deliveries.  

Project Update: 16 January 2020

A collision occurred north of the Park Road junction near the planter/ chicane on the morning of Saturday 11 January 2020. The incident was attended by East Sussex Fire and Rescue and Sussex and Surrey Roads Police. A shop front was damaged after being hit by a southbound vehicle. Fortunately, no injuries were reported by the driver or the building’s occupants. The police have told the Council’s Accident Investigation Officer that they do not believe that the planter/ chicane was the cause of the collision. There are no plans at the moment for further adjustments to the layout of the trial scheme in response to this incident.
