ISSUES FOR THE FUTURE
• Reversing or managing the decline in the condition of the Highways
• Pressure from tripping and other claims
• Residents and visitors perception of the condition of the Highways
• How do we prioritise limited funds?
ISSUES FOR THE FUTURE – MAIN ROUTES AND
RESIDENTIAL STREETS
• Main routes – carry more traffic and thus more wear
and tear– more expensive to repair and maintain.– represent the “shop window” and give
a good or bad impression to visitors to Blackpool.
– Safety and injury risks are greater
• Residential Streets– Tripping claims arise largely from the
“core area” residential footways.– Residents concerns about “their street”
A FUTURE APPROACH?
• Review the funding available for maintenance
• Use available funding and resources to try to ensure that the strategic network (main routes) are kept at the current condition standard.
• Assets which have safety implications shall be given priority for maintenance.
• Residential streets will be maintained to the best standard that can be achieved given the above, with available resources being targeted to areas known to generate claims when appropriate.
