Welcome

Hello everyone and welcome to the February edition of “Keep Things Flowing”, the monthly newsletter presented by Storm Water Consulting.

In this month’s newsletter we review Gold Coast City Council’s recent policy updates and new releases and we review some of the reports that we can prepare to help with your development.

 

Gold Coast City Council Updates

On the 2nd of February Gold Coast City Council adopted the City Plan Version 2 document. The City Plan Version 2 document has two new additions which affect the stormwater related aspects of development.

1.     The addition of a Flood Overlay Code;

2.     New Stormwater Quality Management Triggers;

The new Flood Overlay Code affects land with flooding or the potential to flood. The purpose of the Flood Overlay Code is to ensure development does not adversely impact flooding conditions and to ensure safe and sustainable development. The new Flood Overlay Code assessment criteria can be viewed at the link presented below:

The State Planning Policy (SPP) requires water quality objectives to be met if a development was at least 2500m2. The new triggers (in the City Plan document) for water quality treatment are based on various factors including area, development type and development layout. This potentially increases the number of developments that are subject to meet water quality objectives.

The new Stormwater Quality Management Triggers can be viewed at the link presented below.

As well as releasing a new City Plan, Gold Coast City Council also released a new interactive mapping tool. The new interactive mapping tool features updated aerial imagery, zoning and overlays on a larger display than the previous mapping tool. The new interactive mapping system can be viewed at: http://cityplanmaps.goldcoast.qld.gov.au/CityPlan/index.html

 

SWC Reports

Storm Water Consulting prepare many different types of stormwater reports to support development. Some of the more common reports are summarized below.

Preliminary Assessment Report

This report is typically used to determine whether the stormwater or flooding constraints associated with a property could prevent development. If there is development potential then the approximate design constraints will be identified. This type of report is useful for:

·         Developers seeking information on properties with significant flooding issues

·         Potential purchasers of flood affected properties

·         Sellers of flood affected properties

 

Overland Flow Assessment Report

This report is typically used to identify the extent of overland flow inundation across a property. The proposed development is modelled to demonstrate that no adverse impact is created and finished floor/lot levels are set. This type of report is useful for:

·         Properties subject to overland flow inundation

·         Properties experiencing frequent runoff from external areas

·         Properties in low lying areas

 

Site-Based Stormwater Management Plan Report

This report assesses flooding extent, stormwater quantity and stormwater quality requirements, minimum finished floor level requirements and impacts of development. This type of report is generally used for larger projects. This type of report is useful for developments including:

·         Subdivisions

·         Multi-unit Developments

·         Industrial Developments

·         Commercial Developments

 

Stormwater Quality Assessment Report

This report is typically used to select a treatment train to meet water quality objectives for a development. This type of report is useful for:

·         Properties with a land area greater than 2500m2

·         Properties with a use classed as "High Risk"

 

Flood Impact Assessment Report

This report is typically used to determine the impact of development on a range of flooding sources. Often properties are subject to several sources of inundation and it must be demonstrated that development would not create an adverse impact on neighbouring properties. Sources of flood water include:

·         Brisbane River

·         Creek/Waterway

·         Overland Flow

·         Stormtide

·         Sheet Flow

 

Flood Overlay Code Assessment Report

This report is typically required when using a private certifier to approve a development. This type of report is used when:

·         The development is being approved by a private certifier

·         Submitting a Risk Smart Application

·         There is a reasonably low level of flooding affecting the property
