Report - London Borough of Hillingdon

it could be either a diesel spill or a result of salt in solution
Post salting will only be considered on minor roads not included in the pre-determined routes in
response to a specific report that a particular road is in an icy condition and then only after it has
been inspected to confirm that treatment is necessary.
Minor roads will not be treated with salt until after the pre-determined routes have been
sufficiently treated to ensure that they remain open to traffic at all times. These roads will then
be treated on a hierarchical basis of importance and in response to specific requests from the
Police, public etc.
No action will be taken to treat ice on private roads (i.e. where there are no public right of
highway rights) unless specific arrangements are in place.
5.3 Ad hoc post-treatment
The Highways 24/7 Emergency Call Out team is available with full access to the gritting
vehicles. Should it ever be necessary, this team can call out the Winter Service Team if this
action is required by road conditions.
5.4 Snow Clearance
The decision to move to the snow clearance operation shall be made by the Winter Service Call
Out Officer, following consultation with the Street Environment Manager.
Snow fall of less than 30mm will not normally require any further action than precautionary
salting unless prolonged sub-zero temperatures are forecast.
For snow falls in excess of 30mm or when drifting occurs, post salting and ploughing will take
place on Priority and Secondary routes as soon as is practicable. In the most severe cases it
may be necessary to deploy all available resource to maintain free flow on the major routes and
minimise unsafe conditions.
5.5 Routes for footway treatment.
Footways will only be treated once snow has settled or during periods of prolonged freezing
conditions on a priority basis at locations including (See Annex B to Appendices 1 & 2):
• Town Centres
• Hospitals
• Old Peoples Homes
• Day Centres
• Schools (during term times only)
• Footbridges
• Bus Stops
Secondary footway treatment will be carried out once Priority footways have been treated (See
Annex B to Appendices 1 & 2). If any reports of icy footways are received for locations not
included in on the Priority or Secondary listings, the footway will be inspected to assess
whether it should be treated or not.
