Infrastructure Strategy The Council needs to carefully monitor the potential for increased usage of the lying infrastructure need to be identified. These are listed in the hazard registers of unsealed network as a result of development and commercial pressures. Where road maintenance contracts. possible, Council requires developers to pay for any upgrade to a road which is required to accommodate significant additional traffic. To provide route security from natural hazards the Council will continue to upgrade the land transport network particularly at points of constraint and areas susceptible to Unsealed pavements are relatively cheap to maintain provided the input of the repair closure. or maintenance effort is targeted and timely. Preventative maintenance includes proactively identifying sites with the risk of failure, The current seal extension programme makes use of special rating levies to fund seal and analysing the cost of reducing that risk (eg; a section of road threatened by river extension on selected roads. erosion, or potential slip sites). 3.3 Multiple road users We will also ensure high risk and fragile sections of the network are known and can be proactively managed during events, eg; checking drainage on Port Underwood. Changes to heavy vehicle standards will mean geometric improvements will be required on some remote roads, especially in the Sounds. Another component of risk reduction is to future proof design — ensuring all design of roading renewals and upgrades take account of possible future conditions, for example Crash numbers and crash severity are relatively static with a slow upward trend in the culvert capacities should factor in increased rainfall intensity as a result of climate last two years. Safety is still the top priority on Marlborough District roads.

Investigation into the cause of such incidents Stage 2 needs to be carried out to determine solutions that will prevent further such incidents. Funding will continue to be allocated for this work. Council needs to have provision for managing road closure events, in procedures for contracted service providers to follow, and the ability to fund such work. During The Council will also consider network upgrade options including options for road- widespread weather-related damage the first response is to address public safety and widening, side road closures and the establishment of slow vehicle facilities to meet then to get the roads open to a basic level. the standards of the One Network Road Classification hierarchy. Council’s roading maintenance contracts have in place an Emergency Procedures and 3.4 Earthquake and flood risks Preparedness Plan (EPPP) which it follows during emergency events. Council has budgeted over the next few years to install permanent fold out sign on roads that The resilience plan consists of three stages, as outlined below: frequently flood, eg; Omaka Ford on Old Renwick Road. This will make road closures more efficient. • Stage 1 – reduce risk through maintenance, and taking account of possible future conditions in all design of roading renewals and upgrades Stage 3 Stage 2 – implement emergency management plans when events occur Ensuring that existing infrastructure can withstand the impacts arising from severe • natural hazard events can be managed to some degree, but it is not possible to Stage 3 – recovery after an event, following set processes, to return the network completely protect the asset from being damaged and becoming unusable.
