                      determined as being a highly likely requirement. These services are shown in the images
                      provided at Figures 1 & 2 below.
                      In this regard, MRP have advised that the approved development requires a minimum fire
                      hydrant system pressure of 350 kPa at 20 L/s at the two most disadvantaged hydrant outlets
                      located on Level 2. Historic flow and pressure data for the Cooroy area indicate an available
                      street supply of approximately 390 kPa at 20 L/s. After accounting for pressure losses
                      through the required pipework, valves, fittings, and vertical rise of 9m+ through the building,
                      hydraulic modelling of the hydrant system from the Unitywater water main to the most
                      disadvantaged hydrants indicates the minimum required performance likely cannot be
                      achieved from the Unitywater water main supply alone. Accordingly, provision for a single
                      fire pump housed within a dedicated fire-rated pump room (3m x 5m x 2.1m high) is required
                      to supplement supply pressure and ensure compliance with the applicable fire services
                      standards. Importantly, this has been located clear of Council’s required 6.0m setback from
                      the frontage.




                      Given the need to introduce these utility structures, a suite of amended architectural and
                      landscape plans have been produced by Hollindale Mainwaring Architecture and Project
