Judgment (52 paragraphs)
- The applicant described the "works as executed" in the following terms in the Points of Claim filed 6 December 2000: 4. …The sediment pond includes the following components and features: A It has dimensions of approximately 9.5 metres across the north/south section and 11 metres across the east/west section. B It has a water volume of 57 cubic metres. C The walls are partially constructed of sandstone boulders ranging in size from approximately 600mm to 1200mm. D It has a lining consisting of crushed blue metal stones approximately 75mm in thickness with a geo textile filter fabric laid on top. E The down hill side of the sediment pond including the spillway is constructed of dry packed sandstone boulders approximately 1500mm above the surrounding ground. F A 375mm concrete drainage pipe discharges into the sediment pond. G A manhole and service pit to the concrete drainage pipe are located approximately 18 metres from the sediment pond. H A 1200mm black chain wire fence is constructed on it's northern boundary. I Below the spillway a rock filled drainage channel has been constructed which drains the sediment pond to the adjacent creek. J The total area containing the sediment pond, concrete pipe, manhole and service pit and the fence is approximately 200 square metres.
- Williams describes the works, and the proposed completion of them, in the following terms, in his affidavit of 23 November 2000: 40. The sediment pond has not yet been fully constructed in accordance with Plan No 96/145/2 exhibited at 'RDW4'. Following the Council Order to remove the sediment pond I caused works on the pond to be stopped. The sedimentation pond, as constructed, has the following features: i) It has dimensions of approximately 9.5 metres across the north/south section and 11 metres across the east/west section ii) It has a water volume of 57 cubic metres. iii) the sediment pond walls are partially constructed of rock boulders ranging in size from approximately 600mm to 1200mm. iv) It has a lining consisting of crushed blue metal stones of up to a maximum of approximately 75mm in size with a geo textile filter fabric laid on top. v) The down hill side of the sediment pond including the spillway is constructed of dry packed sandstone boulders approximately 1500mm above the surrounding ground. vi) A 375mm concrete drainage pipe discharges into the sediment pond. This drainage pipe serves Honeyeater Crescent and the second stage of the subdivision. vii) A manhole and service pit to the concrete drainage pipe are located approximately 18 metres from the sediment pond. viii) The sediment pond is proposed to be fully fenced off by a 1200mm black chain wire fence on it's northern boundary. To date the fence has only been partially constructed around the boundary of the sediment pond. ix) Below the spillway a rock filled drainage channel has been constructed which drains the sediment pond to the adjacent creek. x) the total area containing the sediment pond, concrete pipe, manhole and service pit and the fence is approximately 200 square metres. 41. My application for a Building Certificate which I lodged with the Blue Mountains Council referred to in paragraph 34, relates to all of the structures which form part of and are integral to the proper functioning of the sediment pond referred to in items i) to x) above. 42. The following works are still required for the pond to be fully constructed in accordance with Plan No 96/145/2 exhibited as 'RDW.4' which will result in a final cubic capacity of 78 cubic metres: i) The wall of the sediment pond on the low side at the spillway is required to be increased in height by a further 250mm and each side of the spill way by a further 550mm. ii) The sediment pond also requires to be cleaned out and deepened and then relined with filter fabric and a protective layer of blue metal after development of the subdivision lots is complete and stable.
