1.0     INTRODUCTION:


SCG Consulting Engineers have been commissioned by Tim Ditchfield Architects to provide a Storm
Water Management Plan for the proposed development at Lots 1 and 2 on RP116776, 23-25 Sidoni

        •     Manage storm water peak flow rates of runoff and existing flow path characteristics.

        •     Protect against flooding.

        •     Adopt Water Sensitive Urban Design (WSUD) principles throughout.
