DIVISION 15: EROSION AND SEDIMENT CONTROL

Table 14-50 Erosion and Sediment Control

 

 

 

 

$1.1 Site disturbance is limited: to
building areas, their surround and
other use areas;

AND

$1.2 Sediment barriers are
provided throughout and
downslope of disturbed areas to

‘| prevent sediment washing into
.| gutters, drains and watercourse

either on or off the site.
AND

$1.3 All stockpiles including sand,

| soil or building materials are
within the premises and
contained within individual
sediment barriers;
AND
$1.4 Sediment basins are
provided where the site contains
fine or dispersive soils;
OR
$1.5 A stormwater catchpit
incorporating a stormwater
‘| catchpit protection device is

| installed so that all runoff from

disturbed areas flows to the
catchpit;
AND

$1.6 For buildings:

(a) Temporary or permanent
downpipes are connected to
the stormwater system before
laying the roof; OR

(b) Locatised erosion is avoided
by directing flow from
downpipes over non-erosive
areas.

Sediment runoff from all disturbed
areas is directed, via temporary
diversion drains, to sediment
basins at low end of site to
minimise sediment runoff from the
site, as per the Erosion and
Sediment Control Plan, Drawing
No. NO07046-02 by Brown
Consulting.

Sediment fences are proposed to
low lying boundaries of the site to
prevent sediment working into
gutters, drains and watercourses.

All stockpiles will be contaminated
within individual sediment
barriers.

 

 

diverted’

$2.1 Diversion drains or bunds
are designed and constructed to

| drain upstream runoff around the
| disturbed site;

“= | AND

 

 

 

Stormwater runoff will be diverted
to sediment basins as per drawing
No. NO07046-02 by Brown
Consulting.
