Landscape Master Plan

 

Minimum swale inspections shall be conducted monthly during spring and summer with
further monitoring required after major storm events (ie. > 25mm rain in 1 hour).
Inspections during autumn and winter shall be conducted ever 2 months.

Appropriate maintenance shall follow inspections to restore the swale performance if any

of the following conditions are evident.

Typical Swale Maintenance Checklist (Refer to Environmental Management Plans for
detailed Maintenance Checklist to be used at each inspection).

 

Inspection Item

.| Action if Required

 

Gross pollutants — litter & debris

Collect, remove & deposit at Council landfill.

 

Sediment deposits / accumulation

Excavate either by hand or using mechanical
means and deposit in accordance with
Council procedures. Ensure that any areas of
disturb vegetation are reinstated in
accordance with original design and
consistent with other vegetation in swale.

 

Evidence of erosion ie.scour, rilling etc.

Re-establish swale profile and revegetate. In
areas where erosion continues to occur,
suitable armouring (rock, reinforced turf etc.)
will need to be investigated.

 

 

Ponding Ensure swale grade is consistent with original
design and re-establish where deficient. If
reoccurrence occurs, consider installation of
subsurface drainage in problem areas.

Weed growth Remove weeds via manual! methods.

 

Vegetation condition - health & density

Replace dead & diseased plants with -
approved species. Investigate causes if
reoccurrence is noted.

 

Grass condition

Mow during dry conditions — Note that
aeration of the soil may be required if grass
condition deteriorates over time.

 

Damage or vandalism

Repair and or reinstate as required.

 

 

Other or repeated occurrence of above

 

Report, determine cause & rectify.

 

Note: No fertilising or herbicide applications during establishment or during
maintenance of swales as this will impact upon their water quality improvement
function in swales. Photographs of swale elements requiring remediation should
be taken prior to and following corrective actions.

Maintenance of subsurface drainage shall be in accordance with stormwater
management guidelines as described in the Environmental Management Plans.
