COMMENTS
Current situation
The site is currently traversed by a 1050mm diameter Council s<strong>to</strong>rmwater pipeline and easement
along the north western boundary. S<strong>to</strong>rmwater run<strong>of</strong>f from Suakin, Bridge and West Streets,
converge in<strong>to</strong> a road pit on the north eastern boundary <strong>of</strong> No.8 West Street which is then conveyed
downstream, discharging in<strong>to</strong> a natural gully within the adjoining property at the rear, as shown on
drainage layout plan, Attachment 2.
The property is vulnerable <strong>to</strong> overflows in excess <strong>of</strong> the public drainage system or due <strong>to</strong> blockages,
as the drainage pit fronting the site is located in the road sag. Overland flows drain in a south
westerly direction over the gully coinciding with the pipe.
Proposal
Drawings detail measures <strong>to</strong> address conditions 2(a) and 2(b) in Annexure ‘A’. Proposed
mmodifications <strong>to</strong> the <strong>council</strong> drainage system comprise:
