dc.description.abstractRESEARCH QUESTION How can we use green infrastructure to improve the stormwater quality in the suburb of Ahuriri? ABSTRACT Due to changes in the world climate, Napier, a city on the west coast of New Zealand is facing stormwater pollution problems.Perfume Point which is a costal park at the downstream of Ahuriri surbub, suffered from stormwater pollution.This study have shown that some of Napier's stormwater flows through surface runoff, residential areas, and industrial areas and finally merges into Ahuriri and the surrounding harbour. In addition to this, stormwater collected from the roads flows into the estuary along with pollutants. As a result, the Health Authority in Hawkes Bay warns people against any contact with the water in Ahuriri. In particular, untreated rainwater can pose a more severe risk to the environment and people's health. The study aims to use green infrastructure to help improve water quality in Perfumr Point. It sets a series of objectives based on the current situation, including assessing and analysing existing problems with the Napier stormwater system and development around the Ahuriri River. The current study collects data relating to land use, natural conditions and infrastructure around the city by analysing existing theories and case studies. Furthermore, the study will conduct a site survey around the site to analyse specific locations, conditions, issues and opportunities for future development. Building on existing issues, the research question was posed: How can we use green infrastructure to improve the stormwater quality in the suburb of Ahuriri? Based on a literature review of green infrastructure, water sensitive urban design and low impact urban design and development, the creation of rain gardens, depressions, roof gardens, permeable facilities and artificial wetlands throughout the catchment area could help to purify stormwater. A site analysis of the entire catchment area was carried out using ArcGIS. The results showed that stormwater problems will become more of a problem. However, the creation of wetland parks at the Perfume Point, rain gardens, permeable pavements and green infrastructure throughout the catchment can effectively reduce the impact of stormwater pollution. In addition, it is also essential to provide a space for residential activities at Perfume Point.en_NZ
