Background to the HIAMP

• “Well Maintained Highways” – Code of Practice

(July 2005)

• Prescriptive document
• “Highways Maintenance Plan” prior to 2015
• 2015 review produced Highways Asset

Management Plan to align with Policy and Strategy

• New Code of Practice “Well Managed Highway

Infrastructure” introduced in October 2016

Page 155

Review

• Adjusting the Highways Asset Management

Plan to match Central government requests and maintain Local Best practice

– Align to DfT funding streams – Full Risk based approach (where appropriate) – Legal Relevance and Repercussions – Full Risk based approach (where appropriate)

Priority Areas

Adoption of a Risk-Based Approach A Network Hierarchy Review Engagement and Communication with Stakeholders Consistency with Other Authorities Page 157

Code of Practice Structure

• Overarching Principles
• Highways
• Structures
• Street Lighting

Page 158

Risk-based Approach

• The management of current and future risks

associated with assets should be embedded within the approach to asset management. Strategic, tactical and operational risks should be included as should appropriate mitigation measures (HIAMG Recommendation 11 - Risk Management).

• ‘Prevention is better than Cure’

Hierarchy Review

Current Carriageway Hierarchies

• Hierarchy 1 - some of the busiest A roads
• Hierarchy 2 - some A roads, some B roads
• Hierarchy 3 - some B roads, some C roads
• Hierarchy 4/5 - some C roads, all unclassified

roads
