Integrated Catchment Management Plans
 

Background Information

Waitakere City Council (WCC) wishes to allow additional urban development in the north west part of the city and in the New Lynn Town Centre area to provide for economic growth and additional population. Before giving consent to this, Auckland Regional Council requires WCC to prepare plans to show how stormwater will be managed in these areas These plans are referred to as Integrated Catchment Management Plans (ICMPs) and acts as supporting documentation for WCC's application for the respective network discharge consents.

Totara Creek Integrated Catchment Management Plan

To authorise the diversion and discharge of stormwater and wastewater, in accordance with Section 14 and 15 of the RMA.

The catchment area generally described as that land in the Totara Creek Catchment that is bounded by State Highway 16 to the west, Brigham Creek and Dale Road to the north, Trig Road to the east and State Highway 16 and Hobsonville Road to the south.

In addition to the main report, appendices and figures provided below, the following information should be read in conjunction with each ICMP.
