5 The Council officer's assessment report to the Council of the development application under s 79C of the Environmental Planning and Assessment Act 1979 (the EP&A Act) dated 12 December 2007 identified a number of issues concerning the application. In relation to natural hazards it said:
Information available to Council indicates that part of this land could be subject to the risk of flooding by a one in one hundred year recurrence frequency or less. The nearest measured flood levels to the subject site are at the intersection of Old Tuggerah Road and Old Maitland Road Kangy Angy at a level of 12.03 AHD. The area is very flat; however, it appears that the shed is located on land approximately 14m AHD or above, based on the topographic information on Council's GIS system. However, based on the topography and natural drainage line through the site and adjacent to the site, the parcel could potentially be fully flood affected, but this would need to be substantiated by a flood study. At this stage the site will be considered as partly flood affected by creek flooding.
As the site is considered as a local overland flow path and the depth of flooding in a 1% AEP flood event is unknown a precautionary measure of applying a finished floor level of 300mm above the natural surface level should be applied. This is consistent with the Wyong Shire Council Flood Prone Land Policy F5.
There is a waterway that runs through the middle of the property; however, it is located approximately 75m from the proposed dog kennels. It is not considered that the proposed boarding kennels are likely to impact on the waterway.
The subject site is classified as bushfire prone land. The area where the dog kennels are located is shown as Buffer. No new buildings are proposed to be erected as a result of the current proposal and the shed is not habitable by humans.
As the proposal does not involve the construction of any new buildings, a formal bushfire or flood assessment is not required.
Applicants' submissions
6 The Applicants relied on the general provisions in s 79C(1) of the EP&A Act to argue that a mandatory relevant matter was not considered. Additionally, under s 79C(1)(a)(i) cl 23 of the WLEP had to be considered. That clause provides that:
(1) Notwithstanding any other provision of this plan a person shall not erect a building or carry out a work on land which, in the opinion of the Council is within a flood prone area, other than on land within Zone No 2(a), 2(b), 2(c), 2(d) or 2(g), without the consent of the Council.
