  • Brine spraying was popular with town centre shopkeepers – no complaints regarding dirty shops.

  • No detritus left on footways treated with brine spray.

  • Brine spray alone not effective on fallen snow.

  • Priority 1 footways generally treated between 5 – 8am.

  • Pro-active decision making made more effective use of resources.

  • Scope to increase lengths of Priority 2 footways.

  • Community Service groups used to assist in extreme weather conditions.

Roads and Transportation Service Footway Treatments – Winter 2011/12

  • Trial in Kilmarnock extended for a further winter.

  • Calcium chloride to be used instead of sodium chloride. This is effective to lower temperatures and have a longer residual life but is more expensive.

  • Snow ploughs to be available for quad bikes.

  • Monitoring regime to be developed to ensure effective feedback on trial, with comparisons made with control sites.

  • Trigger level for Priority 1 brought forward to 10am, effect is likely to increase number of days of treatment.
