Applicant’s Response

The proposed minor change to Unit 17 will have no negative implications on the existing drainage patterns or
network. The additional Site Cover and Gross Floor Area does not alter the retention of stormwater nor
increase the velocity of stormwater on site.

Refer to Attachment 1 Historic Drainage Plans and the below photographs of the existing drainage patterns
on site. The existing drainage patterns on the site occur either by capturing rainwater via roofed areas and
discharging into the stormwater network, or by the overland flow paths. The paved pedestrian footpaths
throughout The Islander Resort have been designed to direct the overland flow into the stormwater network.

As indicated in the Historic Drainage Plans (Attachment 1) and the below Photographs 1 and 2, a stormwater
pit is located directly adjacent to Unit 17. The pit is located at the lowest section of the paved pedestrian
footpath. The stormwater pit is approximately 300-500mm below the floor level of Unit 17 (and adjoining and
nearby units).

The proposed redesign of the unit (an increase in Site Cover by approximately 10m2) will result in a continuation
of the living areas, and as such is at the same floor level of the existing unit. The minor increase in Site Cover
(roofed area) will greater assist the drainage network of the resort as water will be captured and directly
discharged into the stormwater network rather than an overland flow path.

The internal stormwater infrastructure on the premises is identified in Attachment 1 Historic Drainage Plans.
