Flood Overlay Assessment

Portion of the rear boundary is mapped within the Flood Hazard Overlay Map (OM-FH) – Flooding & inundation extent. The
only addition in the flood area is the roofed pergola (refer screenshot below). The pergola roof is an elevated roof structure
that will not reduce flood storage or imapct flood waters. The pergola will maximise the private open space of the allotment,
providing shade & protection of the rear alfresco area.




The structure is non-habitable, open and unenclosed by walls. The proposal will not contain the storage of dangerous goods
or hazardous material & is sufficiently setback from all boundaries to ensure that water is free draining during a flood event.
The proposed non-habitable roofed pergola is considered a low importance level structure and is highly unlikely to
significantly increase the risks to persons & property from flood hazard events.

Due to the small scale of the structure that will be roofed (<10m), the structure will not worsen the concentration, intensity
or divert flood water in a way that will adversely effect adjoining properties. The pergola footprint is subject to the same
conditions as the existing dwelling; there will be no change to the existing flood storage or flow of flood waters.

The stormwater from the structure is to be connected to the lawful point of discharge.




Dual Occupancy & Multiple Dwelling Code

The proposed dwelling additions maintain compliance with the aceeptable outcomes of the Dual Occupancy & Multiple
Dwelling Code. The additions are non-habitable, of low-impact and will not impact the safety and amenity of residents. The
additions are sufficiently separated from adjoining habitable areas due to the site adjoining a local park in the Recreation &
Open Space Zone.

The proposed pergola, deck & roof additions increase the useability of the site and promote areas of safe, useable, outdoor
private open space. The additions do not impact room for landscaping on the subject site.

The proposed additions do not impact on-site carparking or vehicle access.

Works Code

The proposed dwelling additions maintain compliance with the acceptable outcomes of the Works Code. The dwelling
additions, including the roofed pergola at the rear, ground level deck and roof extension adjacent to the south-eastern side
boundary do not impact vehicle accesss or areas of existing landscaping. The proposed additions require no earthworks and
stormwater is to be connected to a lawful point of discharge.
