Infrastructure Strategy Impact: High. The frequency and costs of high impact natural events could have an Risk: Land may be developed out of sequence and infrastructure will need to be effect on NZTA’s ability to fund emergency remedial work at current Financial installed in a less efficient manner to accommodate the growth Assistance Rates. Level of Uncertainty: Medium Roads assumption: The rate of deterioration of road pavements will remain relatively unchanged over that currently being experienced. Impact: Low. Costs will be recovered from the developer but the return profile may need to be adjusted to meet the inefficiencies of construction Risk: Increased financial and non-financial impacts on roads due to climate change, heavy motor vehicles and/or earthquakes Assumption: Inflow & Infiltration will continue at current rates Level of uncertainty: High, for natural hazard events. Medium for increase in heavy Risk: Increases rates of infiltration will increase flows in sewers and possible vehicular traffic. surcharging. Impact: High. Severe damage could be incurred from a large natural event. Level of Uncertainty: Medium Assumption: Due to the fact the population is spread over a large area and attracts a Impact: I&I beyond current expectations may cause increased overflows, maintenance high number of independently travelling tourists, the community is likely to remain and pumping costs. dependent on private vehicular transport in future. Assumption: Winery waste will continue to be discharged at rates anticipated Opportunity: Use of self-drive vehicles and car sharing trends may further reduce safety risks. Risk: Changes in global markets, health concerns or disease may cause significant change in demand for Marlborough wines Level of uncertainty: Medium Level of Uncertainty: Low Impact: Low. Impact: A significant increase in demand may restrict economic development. A down- Stormwater Assumption turn in demand may result in reduced funding stream.
