TRAFFIC IMPACT ASSESSMENT Executive Summary Introduction WSP-Opus have been commissioned by Manawatu District Council (MDC) to develop a traffic impact assessment (TIA) in relation to the proposed Growth Precinct 4 of the Urban Growth Plan Change. The TIA will be used to support the Plan Change and Section 32 report at time of public notification. The purpose of the traffic impact assessment is to assess the transportation effects of the proposed re-zoning and future residential development of Growth Precinct 4 (with reference to the conceptual roading network) on the efficient and effective operation of the surrounding road network. Study Area The Traffic Impact Assessment focuses on the effects of additional traffic generation from Growth Precinct 4 on the arterial road network located within the immediate vicinity of the development, focusing on the following sites: • Site 1: North Street / Lethbridge Street / Makino Road / Chamberlain
