Edmondson Park South Development Control Plan 2012 - Landcom

Edmondson Park South DCP 2012 November 2012
4.0 Environmental Management
4.1 Riparian Corridors and Water Cycle Management
Stormwater quantity and quality management seeks to reduce the impact of rapid stormwater conveyance on
streams and wetlands, remove pollutants to improve water quality, retain habitats, conserve water, integrate
landscape and recreational opportunities and protect downstream development from inundation. Water
quality detention / bio-retention basins will be an integral part of stormwater management.
Objectives
1. To provide for sustainable urban stormwater management with flood detention basins and water quality
treatment as part of the landscape and water systems.
2. To manage, protect and enhance ecosystems and their biodiversity, soil stability, fauna and aquatic
habitats in natural streams and corridors.
3. To promote development, compatible with stormwater risk and public safety that encourage active and
passive recreation, social, cultural and interpretation opportunities with the corridors.
4. To develop a maintenance strategy that aligns with Council's existing maintenance regime.
Controls
1. Riparian Corridors are to be provided in accordance with Figures 21 - 22, Table 8 below and the relevant
parts of the Edmondson Park South Water Cycle Management Plan, September 2010, prepared by J.
Wyndam Prince.
2. All remnant vegetation along the CRZ must be protected and enhanced unless required to be removed as
part of the re-engineering works to improve the system.
3. Any bank stabilisation measures are to use soft engineering techniques that promote sustainability and
naturalness, except for the Maxwell's Creek Urban Park / corridor.
4. Development, other than low impact recreational facilities and detention basins, is to be excluded from
the CRZ. Recreational facilities include pathways, picnic shelters, seating, educational and interpretative
features. Special attention is to be given to the location and type of facility in the core riparian corridor to
minimise impact on existing vegetation and the ecological integrity.
5. The riparian corridors are to be designed so as to:
a) retain aquatic connectivity through use of crossing structures consistent with the NSW Department
of Primary Industries – Fisheries guidelines,
b) provide access to the water course at locations where the ecological integrity of the existing riparian
vegetation and stream bed and bank stability will not be significantly compromised,
c) provide educational and interpretative features and information in riparian corridors at key locations,
d) be bounded by perimeter streets, and
e) accommodate service utilities only if no other practical or feasible opportunity exists to cross the
corridor at designated crossing points, such as streets and pedestrian crossings.
6. All development is to implement and be consistent with the water cycle strategies outlined in the
Edmondson Park South Water Cycle Management Plan, September 2010, prepared by J. Wyndam
Prince. This includes:
a) on lot treatments (i.e. water wise landscaping, reticulated recycled water etc),
b) street level treatments (i.e. gross pollutant traps), and
c) precinct treatments (i.e. rain gardens, detention basins as shown as Figure 22).
7. Habitable floor levels are to be located above the 100 year ARI floor level plus 500mm freeboard and that
appropriate flood evacuation can be provided for dwellings located below the probable maximum flood
level.
