STORMWATER MANAGEMENT 38
4.4.4 Retention of Vegetation
Where possible, as much native/existing vegetation as possible should be retained. This
vegetation serves a key role in reducing soil erosion (through minimising the impact velocity of
rain drops) and maintaining the soil-water balance. Much of the present SLVA development
area has been undertaken in a way which achieves this goal.
4.4.5 Minimisation of Directly Connected Impervious Area
Wherever possible, impervious areas should not (Figure 4.5) be directly connected to trunk
stormwater drainage systems. Opportunities should be explored to:
• connect impervious areas to dedicated infiltration areas;
• reduce the amount of impervious area by substituting modular pavers for concrete for
example; and
• reuse or recycle impervious area runoff (eg. rainwater tanks)
Figure 4-5 Example of Directly Connected Impervious Area
4.4.6 Education and Awareness
Especially in the case of Smiths Lake, Council will need to consider the preparation of
appropriate education and awareness raising material for council officers, builders and
residents. This material will need to encompass both construction and operational stormwater
issues, and is particularly important given the ‘non-traditional’ nature of proposed site
stormwater management recommendations.
