[21 October 2019] Monaghans Mushrooms access

We are informed that Monaghans have now appointed the contractor to progress construction of the access changes that got planning approval in the summer.  The contractor still needs to finalise a S278 technical agreement with WSCC Highways, but we understand that this should not take long as Highways were consulted in detail at the HDC planning stage.  Scheduling of the works should take place in parallel.  We still do not have a firm start date, but we will continue chasing for this to be as soon as possible and will update residents as soon as this is known.  The PC has been frustrated by the slow progress on delivering this key element of originally-agreed works relating to the Abingworth development.  Amongst the reasons offered by Monaghans’ management has been Brexit uncertainties, as this may have a significant impact on the mushroom-growing business.

[12 July 2019] Monaghans Mushrooms access and HGV routing

Horsham District planners have now given permission for long-awaited proposals to re-shape Monaghans Mushrooms’ front-of-site access arrangements, which are designed to prevent (as far as possible) HGV vehicles from entering or leaving the site in a northerly direction on the B2139.  This was an original planning requirement linked to financial benefit that the Monaghans operation received from the Abingworth Meadows housing development, and seeks to address (albeit only partially) the problem of wide vehicles using the narrow and steeply banked sections of the B2139 over Dukes Hill.  This has taken much longer to progress than the Parish Council expected, which has been very frustrating for the community, but things are now moving.  Full details of the works proposed can be found here on the HDC planning portal.

The new planning permission includes reinstating original conditions relating to HGV traffic to and from the site being routed exclusively from the south, and the Parish Council has made clear to  Monaghans that we expect them to take appropriate steps to reinforce this with its hauliers, and to be pro-active/responsive in cases where this policy is being flouted.  We have also asked Monaghans to ensure that their guidance to hauliers strongly emphasises that HGV drivers need to negotiate the Abingworth traffic calming features in a considerate way for other road-users.

Although planning permission is now secured,  WSCC Highways still require further technical approvals (S278 agreement), so this is being progressed as quickly as possible, with a view to scheduling the works without further delay.  The PC will keep residents updated as the timeline of the roadworks emerges.

It will not escape readers’ notice that, even if Monaghans’ HGV traffic becomes better-managed, there continues to be nothing (except the inconvenience of the pinch-point system) deterring other HGV ‘through’ traffic in central Thakeham.  Unfortunately, WSCC Highways have not been receptive to the Parish Council’s suggestions that a general vehicle width restriction should be applied to this section of the B2139, for safety reasons.  We are told that an order of this kind would first require a strategic framework plan for routing HGVs through West Sussex to be in place, and there is no current prospect or political appetite for such a plan.   The Parish Council will continue to raise this as a policy priority via County Councillors.

Measuring the impact of the Abingworth traffic calming measures

As advised by the safety auditors (see below) Abingworth Homes commissioned a further Traffic Calming Speed Study, comparing traffic speed and volume data measured in week of 29 April – 05 May 2019 to the same data recorded in November 2016, before installation of calming measures.  These are deemed comparable working weeks, during school terms, with no roadworks effects. The full report, now produced, can be read here; its key conclusions are:

Traffic speed

The implementation of the traffic calming scheme has resulted in a very significant decrease in vehicle speeds in the Abingworth 30mph zone of the B2139 Storrington Road.  Using the standard measure (average 85th percentile speeds)

  • Northbound vehicle speeds have decreased by 11.1mph (from 40.1mph in 2016 to 29.0mph now);
  • Southbound vehicle speeds have decreased by 6.3mph (from 38.3mph to 32.0mph now).

Therefore the impact of these measures has brought average vehicle speeds close to the 30mph speed limit.

Of course within these averages, some drivers are still driving too fast, but the proportion of drivers speeding excessively has reduced to relatively low levels.  In 2016, 13% of drivers were travelling at 41mph+, whereas only 0.3% of drivers are now exceeding 40mph.

Traffic volume

The overall traffic volume is effectively unchanged (increase of 0.7%), with weekly vehicle movements in both directions remaining about 3400 per week.  Within that total, there has been some decrease (-16%) in the AM rush hour, balanced by an increase (+10%) in the PM rush hour.  The introduction of traffic calming features will only be one factor in this picture, alongside other local developments including the 2017 move of Thakeham Primary School from The Street to Rock Road, expansion of the Pre-School in its new building, as well as occupations of new housing at Abingworth (approx 75 units).

Based on official police road accident reports, the study concludes that ‘implementation of the traffic calming scheme has not resulted in an adverse impact upon the local highway network in terms of operational safety’.  The Parish Council is very aware that many residents will disagree, particularly in relation to new accident risks created at the northern pinch-point, where the northbound sightline is poor.  The PC is taking these steps to address this:

  • Regular strimming of vegetation on the west verge of the B2139, starting 30 May;
  • Liaising with Hyde New Homes regarding the safety audit recommendation to make an adjustment to the line of the close-boarded fence line behind the Massey Close properties nearest the pinch point.

We will update further on the progress of this as soon as possible.

[22 March 2019]

A further safety audit site visit was undertaken on 21 March 2019 by a team comprising: representatives from Road Safety Initiatives LLP (independent specialists, appointed by the developer), WSCC Highways and Sussex Traffic Police.  The PC Clerk attended in an observing capacity and this report is based on the Clerk’s understanding of what the audit report is likely to recommend (although it is likely to be some time before a formal doc emerges and the developer, who is responsible for the works, responds).
1. Southerly build-out: this feature is considered to be functioning effectively & safely.
2. Visibility from Abingworth Crescent north jct: is now considered to be satisfactory.
3. Northern build-out feature
The specialists concluded that although the way this feature is working is certainly well short of ideal, it meets threshold safety criteria and on balance it can stay in place subject to the developer agreeing & achieving these further steps:
3.1 measures directed at northbound traffic
a)  further improvement of northbound visibility by removing part of the close-boarded fence line behind the Massey Close properties nearest the pinch point.  This is actually a double row of close-boarding to create a walkway for garden/bin access, and it is considered feasible to remove the outer line of fence (replacing with post + rail) without affecting the householders’ amenity.  This could appreciably improve the sightline.
b) an extra SLOW road marking for northbound vehicles approaching the build-out;
c) additional culverted drainage to allow floodwater to escape into the stream by the build-out;
3.2 measures directed at southbound traffic
d)  decluttering of existing signage around the start of the 30mph zone (several redundant signs to be removed and bus stop sign adjusted to not obscure the VAR sign);
e)  adjusting the VAR sign range/aim so that it measures and signals speeds over 30 at a point closer to the village gateway features – it is currently flashing too early.
Failing agreement and delivery of all steps under (3), the fallback will be reconsidering moving this northern build-out 40-50m northwards (which side of the road would be considered further if necessary).
4. Measuring impact of works
The report will strongly advise that re-collection of traffic speed/volume data is necessary, to enable assessment of impact of the installed calming measures, against data from 2017.
Further developments will be published here as soon as available.

[16 November 2018]

WSP consultants leading on this for Abingworth Homes have now completed consultations with WSCC Highways following the safety audit of 10 October 2018, and have confirmed the findings of the audit and next steps as follows:

1. Northern build-out area

In general the safety audit noted that the design of the scheme in this area has been conditioned by the fact that the bends in the road militated against a build-out on the eastern carriageway, which would force southbound traffic into the path of northbound vehicles coming around a blind bend.  The build-out on the northbound carriageway is, provisionally, considered viable, but the audit found that the details of the current implementation are causing some safety concerns that require addressing.

Initial work measures will include:

  • a new sub-plate sign with a ‘Give way to oncoming vehicles’ message installed underneath the existing regulatory sign for vehicles approaching the buildouts
  • Installation of new carriageway-edge road markings around the buildout and opposite kerbline to create a further enhancement and visual narrowing to the existing buildout.
  • Replacement of the existing bollards with new double-sided bollards with yellow reflective panels
  • Further vegetation clearance to maximise visibility.


In addition to these measures, Oakford Homes are liaising with Hyde Homes to investigate the scope to move (or remove) the close-boarded fence north of the northern buildout, to improve the northbound sightline.

To be considered further

The audit has also considered the possibility of additional speed reducing features north of the current build-out (to slow southbound traffic).  Once the first set of remedial works are completed there will be a further safety audit site visit to review the effectiveness of the initial measures and make a recommendation as to whether further works are required.

2. Southern build-out area

In general, the safety audit noted that there was no viable option that would meet relevant requirements for a build-out on the northbound side of the road, and found the current arrangement to be working satisfactorily, subject to this further minor work:

  • Reinstatement of the ‘Slow’ road marking

3. Next steps

WSP are now producing the technical designs and associated details that will then be forwarded to WSCC for final review and sign-off; Oakford Homes will progress the initial works above and are looking to complete this work as soon as possible.

[9 November 2018]

Over the past three weeks the Parish Council has repeatedly pressed the developer’s traffic scheme designers (WSP Consultants) and WSCC Highways to urgently agree and confirm the position relating to further works following the safety audit site visit of 10 October.  The Parish Council is not a direct party to this process.  Further contacts today seem to indicate that a statement will emerge next week. We will publish it as soon as possible.

[late October 2018]

The Parish Council full meeting of 15 October received this update report

  • Traffic calming: the safety audit site visit of 10 October had been informed in advance by a summary of cllr/resident comments. Subject to seeing the resulting report, indications of likely recommendations relating to the northern pinch-point included a possible additional build-out further north on the east carriageway, and improved sightlines and visibility of features in both directions.  The inspector seemed relatively satisfied with the southern pinch-point, but may recommend reinstatement of some of the road markings and additional road surface treatment in tandem with the new southern village gateway feature due to be installed soon on the north side of Jackets Hill.  Additional works can be done under the existing S278 agreement as a framework, but an extra northern build-out would require another neighbour consultation process.  The developer has asked for a list of works to be progressed quickly. The report will also recommend further collection of traffic speed/volume data to assess the impact of the scheme, although this will need to await completion of additional works.

The Parish planning meeting of 22 October received this further update:

  • In relation to traffic calming, the stage 3 safety audit report had been issued to the contractor and WSCC Highways and its  recommendations are apparently in line with the points reported to the last TPC meeting, but there would be a delay while parties digest the recommendations, before a confirmed summary of further works becomes available.

(Action: Clerk to progress reporting of final agreed works to the community).

[late September 2018]

Since installation of the new calming scheme, a number of concerns have been raised by councillors and residents about how the scheme works on the ground, including about the northern arrangement. It is standard that new schemes of this kind have a routine post-implementation safety audit led by specialists independent of both the developer and WSCC. That review is due to happen in the next couple of weeks and the PC will be feeding directly into that process, ensuring that key points of concern raised by residents are fully heard. We will report back to residents on the outcome of this process as soon as possible.

Meanwhile,we are continuing to progress with developer and WSCC the reduced speed limit over Jackets Hill, which is due to be implemented in the first half of 2019.

[July 2018]

The Parish Council is pleased to report that the ‘pinch-point’ scheme for the 30mph zone of the B2139 Storrington Road has now finally been signed off and approved by WSCC Highways, and the works will be progressed urgently during this summer school vacation, with 31 August as the target completion date for main works.  We look forward to this making a real difference to vehicle speeds in central Thakeham from this September.

This will of course mean a month of temporary traffic light controls in this area. As and when the works require temporary relocation of bus stops, Compass Buses are being involved to risk-assess and organise temporary arrangements.

The finalised scheme (which is effectively unchanged from the one consulted-on in January 2018) can be seen/downloaded here.



We also welcome and fully support the recent initiative by resident Ian King to set up a Community Speedwatch group (see his recent Facebook post on our Community page).  It will be important to monitor the impact of the pinch-point scheme, and even if it is successful for that area, there are several other areas of Thakeham with similar speeding problems, so we hope to work closely with this new group when it is set up.

[June 2018]

The Vehicle-Activated Signs at the boundaries of the 30mph zone are now finally operational.

The pinch-point scheme is going ahead: negotiations between the Abingworth developer and WSCC Highways on fine detail of the design seems to be near complete, and the developer has stated the aim of getting the works done during the 2018 school summer vacation.

[March 2018]

Following the frustration of the installation of the vehicle activated signs in the Abingworth 30mph zone being set back by the contractor going out of business, latest news is that a new contractor has taken on this work and we expect installation to commence this month.

The latest on the pinch-point scheme is that the consultants say that they are on track with translating the consulted design into a detailed agreement with WSCC Highways; we will keep pressure up for the work to start as soon as possible.  Monaghans Mushrooms have also agreed to re-start steps (including a planning application) to re-shape the front of their site, with features to prevent HGVs turning north up the B2139.

[October 2017] Traffic Calming: Phase 2 revised ‘pinch point’ scheme now available for comment

We have now finally received the revised/refined proposal for the Abingworth Phase 2  ‘pinch point’-based traffic calming scheme, which you can see and download below.  The PC will be reviewing this scheme at its Neighbourhood Planning Committee meeting of Monday 23 October (6.30pm, Village Hall).  The feedback that we give to the consultants who have produced the scheme will influence the detail of what is then formally submitted to WSCC Highways for approval.  We want this submission to be made by the end of November, to allow sufficient time for Highways to consider/approve and for the developer to schedule the work for Spring 2018.  Given the long history of resident concerns and the terrible fatal accident in March 2017, the PC is seeking widest possible community comments on the new scheme.  You can give your input either by attending the meeting above, or email  by close of Friday 27 October.  The PC’s planning group will take on board all comments received by then.

Reduced speed limit over Jackets Hill

Although the scope of the proposals above are limited to the Abingworth 30mph zone itself, we are also continuing to pursue the extension of the 40mph limit from the northern edge of Storrington over Jackets Hill.  WSCC Highways and Sussex Police have indicated that they are open to this, subject to the lower speed limit being supported by vehicle-activated speed signage, and financial commitment to this was secured from Abingworth Homes as part of planning permission granted for the revised phase 2 housing scheme in April 2017.   We will continue to progress this in parallel with the scheme within the 30mph zone, aiming for implementation in 2018.

Phase 1 works – latest as at October 2017

We have continued working with the developer and WSCC Highways to deliver the ‘phase 1’ traffic calming measures around the Abingworth 30mph zone that have been approved in principle by HDC planners.  These works comprise: vehicle-activated signs (VASs), village gateway features, and signage upgrades.  Progress has been frustratingly slow due to the many steps required to get relevant Highways approvals and infrastructure in place (e.g. electrical connections to the locations of the VAR signs).  However, we do seem now to be finally on track for this work to happen in November 2017.

Previous background

Who does what
WSCC Highways are responsible, and are the decision makers, on all matters relating to roads, and road safety.  Where road layout and safety issues are linked to housing/business development projects, that also brings in the Horsham District planning process.  As in the case of the Abingworth development, planning agreements can provide funding and design proposals for certain road improvements, but the detailed design still has to be agreed and signed off by WSCC Highways. That process involves statutory consultations, including with the police, which are led by the developer. The PC’s role is to consult with and, via these processes, act as the voice of the local community to push for the changes that our residents want.

Abingworth 30mph zone

While the details of the incident that caused the recent death of a young resident remain for the inquest to determine, the community is well aware of long-standing issues with the 30mph limit in the Abingworth area being ignored.  There is a long back-story to the PC’s lobbying to get this situation improved, but this is the current situation:

April/May 2017: This pass of work around the southern access to the Abingworth Meadows housing development had been scheduled for some time, and involves:

Southern access junction area

Works here will improve sight lines and will involve:

  • New signage for northbound drivers approaching from Jackets Hill;
  • New footway north of the access junction and a new pedestrian crossing point next to Stringers Cottage. (Not, as yet, a light-controlled crossing but see Phase 2 plans below.)
  • Footway on west side of B2139 extended southwards to northbound bus stop
  • Both bus shelters will be replaced/reconstructed.

During these works, temporary bus stop arrangements have been agreed with Compass and WSCC Education Travel team.

Northern access junction area

We also need improved pedestrian crossing arrangements around the northern Abingworth junction, which is where the new shop and village hall will be. Following directly on from the southern works above (i.e. May 2017) will be works to improve sightlines and the pedestrian crossing arrangements around the northern Abingworth junction.  This will include moving the current crossing north of High Bar Lane to a better visibility point slightly further northwards.

School bus stops – longer term

The Parish Council’s view that there remains more to do to make the school bus pickup points safer (preferably off the Storrington Road altogether), as well as continuing to improve pedestrian crossings. We will continue looking into the options and opportunities as the Abingworth development moves forward.

Further phases of Abingworth traffic calming works

The PC has agreed designs for the following further works with Abingworth Homes, but details and timing of delivery remain dependent on HDC planning and WSCC Highways consultations/approvals – see ‘who does what’ above.  The phasing below relates to planning technicalities, but the timeline that the PC and the developer are seeking to work to is to deliver as much as possible of both phases below by early autumn 2017. 

Phase 1

This pass of work is due to include:

  • New village ‘gateway’ features and speed indicator devices at both south and north ends of the 30mph zone.
  • Further improvements to speed control signage and road surface treatments, including ’30mph’ roundels.

Drawing of Phase 1 works as part of HDC planning proposal DC/16/2835

Phase 2

The planned further works are as below.  The detail of this is subject to further consultation with WSCC Highways, residents and other consultees.

  • The addition of several further build-outs into the B2139 roadway to create a ‘pinch point’ priority system enforcing the 30mph limit through the whole 30mph zone.
  • a new bridleway crossing near the northern access junction (at the southern edge of the new local worker housing). This will form a westward extension of the new east-west bridleway through the Abingworth site, which will rejoin High Bar Lane near the playground. The design involves the east side of the crossing being built out into the road.
  • New 40mph speed zone over Jackets Hill, i.e. extending the current 40mph limit northwards from its current limit at Merrywood Lane; this will involve an additional vehicle activated speed indicator display;
  • New footway along the east side of the B2139 north of Merrywood Lane, creating a safer link for pedestrians/cyclists between the edge of Storrington and existing bridleways and footpaths to the Abingworth area.  This will include upgrading the full length of the Strawberry Lane bridleway.

Other areas of road safety concern

While we are currently focusing mainly on the Abingworth area, the PC is aware that there are real road safety issues in a number of other areas within the parish, including:

Rock Road area

We remain concerned about the safety of pupils commuting on foot/bicycle near the Rock Road school site, both at the Water Lane roundabout, and on the footways northwards, which cross the busy B2139 several times.  Thakeham PC and Storrington & Sullington PC are pressing WSCC Highways to bring forward improvement schemes.  Frustratingly, Thakeham already has potential funding available to assist with this (£60K from a past development), but has so far been unable to get WSCC to engage with this.

Picketty Corner  (jct of the West Chiltington Road with B2139/Coolham Road)

This junction, and the stretch of the B2139 to the south, are dangerous with many recent minor accidents and near-misses. Although WSCC Highways have rejected a proposal for a new 40mph speed limit on the bends south of Picketty Corner, they have agreed to implement improvements to signage, road treatments and vegetation cut-back which should improve warnings to motorists and sight-lines.

Junction of Crays Lane with Goose Green Lane

This is a dangerous junction with very poor sight-lines for drivers emerging from Crays Lane to turn eastwards onto Goose Green Lane in a 60mph zone.  WSCC Highways have agreed to add improved signage and vegetation cut-back works to their list of upcoming improvement works.

Other areas of concern regarding excessive average traffic speed

These include:

  • The B2139 between Harbolets crossroad and Coolham; 
  • Greenhurst Lane.

We will move on to prioritise these areas as soon as possible.
