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

OPERATIONAL PHASE:

e Perform routine inspections of the raingarden (VBFS) to identify any areas of obvious increased sediment deposition, scouring from

 

storm flows,

RECOMMENDATION:

| 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

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.

SPECIFICATION

 

(NOT TO SCALE)

 

NOTES:

1. Provide selected plants as to specification of
"Healthy Waterways” http://www.healthywaterways.org/

2. Provide "FOREBAY’ made of rocks and pebbles. For
scour protection. Refer detailed design for area.

 

 

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

The maintenance of the bioretention basin elements involve:

e — Routine inspection of the bioretention basin profile to identify any areas of obvious increased sediment

NOTES:

1.
2.

3.

Use LUCERN OR EQUIVALENT for mulching
Do not use organic Soils or soil fractions
for filter layer.

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.

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

. Geotextiles may be used in addition to the

impermeable concrete & block surrounds.

. Provide flush out points for subsurface

drainage.

Removal of sediment where it is smothering the bioretention basin vegetation.
e 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

Pruning to remove dead or diseased vegetation material and to stimulate growth.

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
