Nil
2.5 SOIL AND WATER MANAGEMENT WORKS
These works are to undertaken on an ongoing basis by the landscape
contractor.
2.5.1 Generally
All soil and water management works shall be undertaken before the
commencement of earthworks.
All works must be in accordance with The Hills Shire Council’s standard
practices for Soil and Water Management.
For the purposes of this specification soil and water management works
include:
erosion and sediment control measures that minimise sediment
pollution to downslope lands and waterways
measures to avoid altering the drainage pattern in relation to adjoining
land.
2.5.2 Clearing
The site is presently developed with adequate cover over all areas. Where
possible this cover must be retained until the final turfing can commence.
All reasonable measures will be undertaken to protect all other vegetation on
the site from damage during construction, including the erection of individual
or group fencing.
2.5.3 Land Disturbance
Where practical, the soil erosion hazard on the site will be kept as low as
possible. To this end works should be undertaken in the following sequence, if
required.
Approved runoff and erosion controls will be installed before clearing site
vegetation other than those associated with the construction of the controls.
A ‘silt’ fence shall be installed along the existing boundary fences below the
site works and maintained for the duration of the works.
Topsoil will only be stripped from approved areas and will be stockpiled for
later reuse during site rehabilitation and landscaping.
Stockpiles of topsoil, sand, aggregate, spoil or other material will be stored
clear of any drainage line or easement, natural or artificial waterbody, footpath
or road surface. They will have measures in place to prevent the movement
of such material onto the areas mentioned.
North Rocks Pre-school Landscape Specification
Playground
__________________________________________________________________________
Page 5
Undertake site development works in accordance with the landscape plans.
Where possible, phase development so that land disturbance is confined to
areas of workable size.
Final site landscaping will be undertaken as soon as possible and within 15
days of completion of construction activities.
2.5.4 Sedimentation Control
Water will be prevented from entering the permanent drainage system unless
it is relatively sediment free ie. the catchment area has been filtered through
an approved structure.
Temporary soil and water management structures will be removed only after
the lands they are protecting are rehabilitated.
All disturbed lands will be rehabilitated promptly and effectively and within
fifteen days of completion of work or other period as specified on the soil and
water management plan.
