Outcome: Recommendations Approved

Is Key Decision?: No

Is Callable In?: No

Purpose:

Content: To approve the appointment of a consultant to undertake an origin destination Automatic Number Plate Recognition (‘ANPR’) survey and to provide an air quality modelling study for the Storrington Air Quality Management Area (‘AQMA’).   To approve the award of the required consultancy contract (‘the contract’) to the supplier identified and at the cost outlined in the exempt appendix.   To finalise the terms and conditions of, and to approve the entering into of, the contract in consultation with the Head of Legal and Democratic Services.     Horsham District Council declared an AQMA in Storrington in 2010 due to NO2 exceedance. The last Air Quality Action Plan (‘AQAP’) was made in 2020, setting out the measures that would be put in place to improve air quality within the AQMA. Work is currently underway to update the AQAP.   The Council is interested in exploring measures to reduce traffic levels currently using the A283 in Storrington AQMA. It is suspected that a good number of vehicles (such as the diesel cars and HGVs) that use the A283 are through traffic, which are avoiding the A27 due to congestion. The Council is interested in establishing the origin and destination of the traffic using the A283 to understand the proportion of through-traffic for the purposes of exploring: (i) the potential air quality improvement that can be achieved from different scenarios that would deter the use of the A283; and (ii) whether other behaviour change campaigns and traffic management schemes (i.e. advisory routes, diversions) can also deter the use of the A283.   The delivery of a consultant’s report on the air quality improvement associated with these scenarios can then be shared with West Sussex County Council to support with identifying the preferred traffic related air quality mitigation approaches for the Storrington AQMA.   Other Air Quality Action Plan measures have been considered to improve air quality in the Storrington AQMA such as: (1) implementation of a 7.5T weight limit restriction on the B2139 School Hill in Storrington to reduce heavy vehicles accessing the AQMA; and (2) the A27 Arundel bypass (which would start at Crossbush and reconnect with the existing A27 in the west near the A27/A29 Fontwell (east) roundabout and reduce traffic flows through Storrington where longer distance traffic is avoiding the A27 due to congestion). However, regarding these: (1) despite this 7.5T weight limit restriction, there have been several breaches; and (2) it has been confirmed that the A27 Arundel bypass will no longer be taken forward. So other strategies now need to be explored (see above).   None
