Skerningham THE PLAN PERIOD UPTO 2036

• Skerningham has an allocation of UPTO 1800 houses in the Draft Plan period.

• Increased numbers are a possibility through Garden Village Status which could increase this UPTO 2400 in the plan period

BEYOND 2036

• The development of UPTO 4500 houses will be well beyond the Local Plan Period and be subject to all of the Controls mentioned earlier.

MASTERPLAN & ISSUE

Access through the Park and the park itself has been raised as an issue to consider


Initial Traffic Assessment Findings Springfield Link Road has NOT been found to be critical at this initial stage of assessment.

However, the initial findings show it is very BENEFICAL.

If Springfield Link Road is not developed more detailed junction assessments will be required..

Key Findings without Springfield Park Link Road:

• Additional traffic on existing roads requiring further mitigation to be identified.

• Reduced public transport access points and possible service to Skerningham

• Additional impact on the existing junctions on Whinfield Road (A1150)

• Other access points may need to be considered.

• Not as good Quality of Place

• More concentrated development in early stages

• Will make early delivery of new services and facilities in a centrally located site more difficult.

• Impact on timeline of Local Plan and associated risks due to further traffic modelling work to validate and identify mitigation schemes.

WITHOUT Springfield Park Link Road

• Development of housing likely to be more focussed towards Barmpton Lane North • Whinbush Way carries an extra 4094 vehicles per day above 2017 levels. • Barmpton Lane North an extra 2976 vehicles per day from 2017 levels • Additional traffic on A1150 makes access from side streets more difficult in peak times.

Leading to significant queuing at Stockton Road and Whinbush Way junctions. • May need to consider additional access points

Traffic levels on A1150 increase. In both Scenarios there is a slight reduction of vehicles on Barmpton Lane South as ability to access Stockton Road is more difficult in peak hours making it less attractive and pushes traffic via Whinbush Way Traffic Signal controlled junction.


• Whinbush Way carries an extra 945 vehicles per day above 2017 levels. • Barmpton Lane North an extra 3697 vehicles per day from 2017 levels • May need to consider additional access points

At this point it is essential that the Skerningham internal network is delivered including a bridge across the ECML to the A167. The road network built as part of the Garden Village starts to enable alternative routes and mitigates against the housing development numbers. Additional east/west movements on A1150 will lead to congestion at Stockton Road and Whinbush Way junctions.


The modelling has been undertaken in 5 years blocks………

The completed infrastructure at 2030 shows a supporting network and alternatives for traffic.

However, between 2025 and the 2029 the traffic numbers will increase on existing local roads until a full NEW road network is completed at 2030.

! 2029 scenario may look like this ……


2029 Scenario just before Full 2030 Infrastructure in place WITH Springfield Park Link Road

• Springfield Link Road carries 6,021 vehicles per day…… • Whinbush Way carries an extra 1,832 vehicles per day above 2017 levels. • Barmpton Lane North an extra 1,755 vehicles per day from 2017 levels.

Traffic levels on A1150 increase. It is this scenario where the link road through Springfield Park provides an alternative to increasing traffic significantly on the exiting Local Roads The new access point to the east offers an alternative route


2035 – Assumes UPTO 2,400 houses built WITH Springfield Park Link Road WITHOUT Springfield Park Link Road

• Whinbush Way carries an extra 562 vehicles above 2017 levels. • Barmpton Lane North an extra 2949 vehicles from 2017 levels.

• Whinbush Way carries an extra 489 vehicles above 2017 levels. • Barmpton Lane North an extra 3798 vehicles from 2017 levels • May need to consider additional access points

At this point it is assumed the Skerningham internal network is delivered including a bridge across the ECML to the A167. The road network built as part of the Garden Village starts to enable alternative routes and mitigates against the housing development numbers. Additional east/west movements on A1150 will lead to significant congestion at Stockton Road and Whinbush Way junctions. Motorists will start to use the development access road as a by-pass. Additional mitigation schemes required to enable further housing beyond Local Plan numbers.

Access Points from estate adjacent to Springfield Park


Conclusions

Springfield Link Road has NOT been found to be critical at this initial stage of traffic assessment.

However, the findings show it is very BENEFICIAL and particularly prior to the NEW distributor road network being completed around 2030.

If the Springfield Park Link Road is NOT developed both Barmpton Lane and Whinbush Way have sufficient theoretical link capacity to carry this additional traffic. However, it does add significant traffic numbers onto existing local roads.

The junction capacity has not been assessed at this stage and would require further modelling work to determine whether the junctions can be improved to accommodate these levels of traffic.

The Springfield Park Link Road or Alternative Access Points could yet be found to be REQUIRED if junctions cannot be improved to accommodate the traffic predictions.

The traffic on the A1150 will increase and there will be junction delays where local roads meet the A1150 but this will be more significant for local residents without the Springfield Link Road.
