OPERATIONAL PHASE:

RECOMMENDATIONS FOR ESTABLISHMENT & OPERATION:

PHASE OF ESTABLISHMENT:

The first 2 Years after construction are crucial for the performance of the VBFS.

“Ensure the right plant selection (refer "Healthy Waterways" for plant selection)
**During dry periods provide sufficient watering

****Perform regular weed removal

****Replace not established plants where required

Perform routine inspections of the raingarden (VBFS) to identify any areas of obvious increased sediment deposition, scouring from
storm flows, rill erosion of the batters from lateral inflows and clogging
Perform routine inspections of the inflow systems in particular the grated drain and clean the grated drain regular from debris and litter
Perform routine inspections of the surface of the raingarden and clean from litter and gross pollutants
Remove sediment build ups in the raingarden

Repair any damage from vehicle traffic

Provide regular irrigation/watering during extended dry periods
Remove any invasive weeds at any time

Remove plants that have died and replace them

Perform regular pruning as to Landscape Architects schedule to encourage growth and healthy establishment of plants

Perform vegetation pest minotoring and control as to Landscape Architects schedule

RECOMMENDATION:

THE RAINGARDEN IS PROPOSED TO BE A STORMWATER TREATMENT DEVICE AS OPPOSED TO A NORMAL GARDEN
BED. WE RECOMMEND TO SET UP A SIGN EXPLAINING THE PURPOSE OF THE RAINGARDEN.

MAINTENANCE PLAN

 

The maintenance of the bioretention basin elements involve:

WATER SENSITIVE URBAN DESIGN TECHNICAL DESIGN GUIDELINES FOR SOUTH EAST
QUEENSLAND (Chapter 5, Item 5.6).

Routine inspection of the bioretention basin profile to identify any areas of obvious increased sediment
deposition, scouring from storm flows, rill erosion of the batters from lateral inflows, damage to the profile

from vehicles and clogging of the bioretention basin (evident of "boggy" filter media surface).

Routine inspection of inflows systems, overflow pits and under-drains to identify and clean any areas of
scour, litter build up and blockages.
Removal of sediment where it is smothering the bioretention basin vegetation.

Where a sediment forebay is adopted, removal of accumulated sediment.

Repairing any damage to the profile resulting from scour, rill erosions or vehicle damage by replacement of
appropriate fill (to match onsite soils) and revegetating.
Tilling of the bioretention basin surface, or removal of the surface layer, if there is evidence of clogging.
Regular watering/irrigation of vegetation until plants are established and actively growing.
Removal and management of invasive weeds (herbicides should not be used).

Removal of plants that have died and replacement with plants of equivilant size and species as detailed in

the plant schedule.

Pruning to remove dead or diseased vegetation material and to stimulate growth.
Vegetation pest monitoring and control.

Refer "Water by design" by HEALTHY WATERWAYS.

TREATMENT TRAIN

1. Use LUCERN OR EQUIVALENT for mulching

2. Do not use organic Soils or soil fractions
for filter layer.

3. Provide a suitable irragation system required
for the establishment of the plants and for
use in extended dry periods. Irragation
system shall be supplied from the

harvesting tanks.

4. Do not use any geotextile or related
products between filter and transition or
between transition and drainage layers.

5. Geotextiles may be used in addition to the
impermeable concrete & block surrounds.

6. Provide flush out points for subsurface
