Infrastructure Delivery Plan (Feb 2013) - Runnymede Borough Council

Runnymede and its surrounding areas result in an overall increase in additional traffic
and associated congestion on the non strategic road network. It is likely however that
the TIA will conclude that any potential increase will not cause a material increase in
traffic flow on the network or at M25 Junctions 11 and 12. As such, the Local Plan will
not result in an unacceptable level of congestion at these junctions. The risk of
IDPR009 is therefore considered to be low, and the severity is considered to be
medium.
6.50 Three risks were identified which are summarised in the table below.

6.51 Development proposals over the course of the Local Plan are likely to place additional
pressure on the non-strategic road network that serves the Borough. With the
exception of some localised issues (in this regard, the County Council has indicated
that it would be desirable to have some improvements to the network that will address
safety and localised congestion over the plan period), it is highly likely that the TIA
2012 will conclude that the overall increase in traffic growth over the plan period within
Runnymede, in combination with other similar developments will not significantly affect
this infrastructures capacity. Therefore, although congestion is likely to increase at
peak hours, the distribution of new development across the Borough over the plan
period (including that being proposed for the DERA site) is unlikely to affect this
conclusion. The preliminary conclusions which have been drawn in this chapter will
however need to be confirmed by the TIA.
6.52 Of the three identified risks identified above, IDPR007 is likely to be the only one that
the Borough could reasonably influence as the other risks are outside the Council’s
control.
Rail infrastructure
Existing conditions
6.53 The majority of rail infrastructure is the responsibility of Network Rail, with services
being provided by Train Operating Companies (TOC’s) under franchise agreements
with the Department for Transport (DfT). Runnymede has 6 railway stations:
Addlestone, Chertsey, Virginia Water, Egham, Byfleet and New Haw, and, Longcross.
All of these stations are believed to be leased from Network Rail by South West Trains
(See Figure 15).
