Resource Consent Application U061021

Marlborough District Council was granted for a resource consent to discharge stormwater from the Adams Lane and Rose Street catchments to Murphys Creek. The consent expires in 2012 and its purpose is to provide for the disposal of stormwater from a developing catchment, in the short term, while options for upgrading the stormwater system in the longer term are finalised.

Scenario Diagrams

The scenario diagrams included within the report are better viewed individually. The scenarios represent different development possibilities and the consequences of these for the discharge of stormwater.

There are five scenarios. In all five a 2002 aerial photo of the areas provides a common base. Coloured shading and hatching depicts different development scenarios. The existing stormwater network (pipelines and manholes) is also shown, together with the options for upgrading it.

The inset is a blow-up, to show more detail of the design flows and the discharge point to the upper reaches of Murphy's Creek. This occurs at point A, adjacent to Middle Renwick Road.

Scenario 5 is the subject of resource consent application U061021.
