Neptune Homes are seeking a side boundary setback relaxation for 21 Central Avenue along the North-Eastern side, reducing it to 530mm. In the Siting Assessment Report submitted as part of this application it is claimed the setback should be 1400mm, but according to the contour plans submitted to Council at the time Lot 4 was subdivided in 1998, the true height of the building above Natural Ground is greater than 7.8m due the Natural Ground Level at registration of this subdivision in 1998, being below 32.0m across the rear of the proposed development. Based on Council Code MP1.2 for lots of greater than 450m2 with a width of 12.1m, the boundary setback where greater than 7.5m above natural ground should be 2000mm. This means that the relaxation being sought is 1470mm.
The plans submitted with the application by Neptune Homes show the planned building height to be 6964mm including the supporting slab (310mm). The platform level shown for the site is 33.140m. This is an increase of more than 1140mm above the Natural Ground Level of 32.0m as determined when the Lot was subdivided in 1998. The significant amount of fill required to achieve the planned platform height will result in a retaining wall along the northern boundary of over 2.0 metres in height.
This substantial relaxation has the effect of considerably increasing the overshadowing along the length of the adjacent properties at 25 and 27 Central Avenue, not to mention creating several significant overland flooding and safety issues:
• Undermining and or over-loading the existing retaining walls along the length of this boundary.
• Creating significant overland flooding along the length of the North-Eastern boundary and into the neighbouring properties.
• Destruction of the existing 40 metre long Murraya Hedge running the entire length of the boundary which has been carefully cultivated and maintained for privacy and amenity over the past 30 years
• Substantial overshadowing of the properties at 25 and 27 Central Avenue.
I urge Council to reconsider the request for variation based on the flawed information provided by Neptune relating to the Natural Ground Height, as well as the significant risks to the adjacent properties.
