Water Sensitive Urban Design<br />
Figure 17 - Bollards or kerbs with regular breaks allow distributed flow to the <strong>WSUD</strong> element while protecting these systems from traffic<br />
••<br />
Street-scale <strong>WSUD</strong> elements should be<br />
part of an overall <strong>WSUD</strong> strategy for a<br />
development (Figure 16).<br />
••<br />
It is not necessary to provide <strong>WSUD</strong><br />
elements on all streets, however<br />
streetscape <strong>WSUD</strong> elements may form<br />
an important part of a <strong>WSUD</strong> strategy<br />
for a development.<br />
••<br />
Parking areas can be located adjacent<br />
to <strong>WSUD</strong> elements, but should be<br />
designed to prevent vehicles damaging<br />
these systems. Bollards or kerbs with<br />
regular breaks are required to allow<br />
distributed flow to the <strong>WSUD</strong> element<br />
(Figure 17).<br />
••<br />
Parking areas may be interspersed<br />
between <strong>WSUD</strong> elements, such as<br />
parking bays between raingardens.<br />
An example of a road cross-section is<br />
shown in Figure 18.<br />
Different types of streets will lead to<br />
different opportunities for <strong>WSUD</strong>. Model<br />
street types described in L<strong>and</strong>com’s Street<br />
Design Guidelines are listed in Table 4<br />
along with potential <strong>WSUD</strong> opportunities.<br />
