Schedule 4A Assessment of Compliance

 

Specific Outcome

A probable Solution

(b) subject to paragraph (c), the bottom
edge of the base of a retaining wall,

under the retaining wall, revetment
or seawall for at least 50 years;

(c) if a relevant planning scheme
standard is more stringent than the
standard mentioned in paragraph (a)
or (b)—the relevant planning

Comments

 

 

19.4 Prescribed tidal work that is a
retaining wail, revetment or seawall, is
not adversely affected by hydrostatic
pressure behind the retaining wall,
revetment or seawall.

 

The design and construction of the
retaining wall, revetment or seawall is
consistent with the following

standards—

(a) subject to paragraph (b), airetaining
wall, revetment or seawall provides for
drainage holes, and suitable filter material
behind the holes, to

telieve any hydrostatic pressure

behind the retaining wall, revetment or
seawall;

(b) if a relevant planning scheme standard
is more stringent than the

standard mentioned in paragraph
(a)—the relevant planning scheme
standard, to the extent it is more
stringent than the standard

mentioned in paragraph (a).

 

Geotextile behind the rock wall will provide necessary
protection against hydrostatic pressure.
