Environmental framework Print

​​​​Two of the four principles of WSD refer to natural systems, namely 'Protect and enhance the values and functions of natural ecosystems'; and 'Mimic natural systems and processes for stormwater management'. 

An environmental framework such as that in Figure 15 determines the value of existing on-site environmental resources at the regional, catchment and site scale. Site layout is then optimised to protect and enhance on-site resources. An environmental framework is built from the data collected during the Site Assessment phase. 

An environmental framework is a means to ensure that sufficient ecosystem services are provided in a site or catchment to support the wellbeing of communities in current or future developments. It ensures the principles of WSD are considered by protecting and enhancing a site's natural systems across open space networks, ecological corridors, receiving environments and enhanced landscapes. A project team will generally consider the following site elements or attributes as part of a combined environmental framework: 
  • Landscape and natural character values 
  • Soil and riparian ecosystems 
  • Biodiversity values to ensure native species resilience 
  • Ecosystem connectivity to ensure ecosystem resilience. 
To assist with the determination of values, Auckland Council has produced several documents which provide guidance for developing an environmental framework. These are: 
  • TR2009/083 Landscape and Ecology Values within Stormwater Management (Lewis et al., 2010) 
  • Criteria for the Identification of Significant Ecological Areas in Auckland (Sawyer & Stanley, 2012). 
Environmental frameworks are prepared by ecological and landscape specialists to ensure the classification and optimisation of on-site resources is completed correctly. Getting these specialists involved early on in the Site Analysis phase provides the best opportunity to maintain and enhance the environmental resources of a site.​
