Att 8 - SWMP

             1. Introduction
             1.1 Scope
             This Stormwater Management Plan (SWMP) has been prepared to support a development
             application for Material Change of Use for a proposed commercial development at 11-19
             Hilton Terrace Tewantin. A proposal plan is provided as Appendix A.

             This SWMP has been written to address stormwater quantity and quality generally in
             accordance with Noosa Plan requirements and the Queensland Urban Drainage Manual
             (QUDM, 2013).

             1.2 Site Description
             The existing site is almost completely impervious, comprising a number of buildings and
             hardstand areas. Figure 1.1 shows existing site conditions and surface coverage.

             The site is low-lying, having surface elevations generally between 1.0m and 2.0mAHD. As
             such, the site will need to be filled in order to achieve adequate flood immunity and will
             therefore be raised above the existing verge level.

             A small stormwater catchment associated with Ernest Street flows into the site via an
             existing pipe on the Eastern Site Boundary and is shown in the site survey provided in
             Appendix B. This external catchment will need to be accommodated in the stormwater
             design for the site.
