The Sediment Taskforce has brought the private and public sectors to look at the problem of sediment loss from subdivision, building sites and roadworks entering our storm drains and waterways.
A new series of information sheets has been developed by the Sediment Task Force to help Western Australian builders, land developers, Local Government Officers, homeowners and residents prevent water pollution by keeping soil on site.
A summary of current data and case studies illustrating the economic costs of unmitigated erosion and sediment loss during subdivision, residential and commercial building construction and roadworks.

This report summarises findings from a research project commissioned by the Sediment Task Force, which is a partnership between Perth Natural Resource Management (NRM), the Department of Biodiversity, Conservation, and Attractions (DBCA) and other government environmental managers and enforcement agencies, leading housing industry groups, local government authorities, and community groups. The Sediment Task Force represents a collaborative approach to develop solutions that prevent sediment run-off, particularly, but not exclusively, from building sites.
This project was established to provide field data that identifies activities producing water-borne sediment, and the conditions under which that sediment is discharged from an urban development site, where land is being subdivided, landscaped, and roads and houses constructed. This project specifically aimed to:
Soil erosion from building, subdivision and construction sites is a major source of stormwater pollution in urban areas of WA. When it enters our waterways or wetlands, sediment (soil, sand, silt and mud) washed from urban areas can cause short and long-term environmental problems.
Sediment can block drains, leading to localised flooding, and obstruct and/or damage stormwater drainage infrastructure and Water Sensitive Urban Design technologies; often resulting in Local Governments having to pay to fix the damage.
Local Government Officers (LGOs) are often charged with the task of monitoring for compliance with State legislation and their own local laws, policies, plans and/or guidelines for erosion and sediment control.
To help LGOs in this important work, the Sediment Task Force has developed an On-Site Checklist for Inspecting Soil Erosion and Sediment Loss from Building, Subdivision and Construction Sites which aims to assist LGOs to quickly identify and inspect incidences of soil erosion, sediment runoff, sand drift and dust from building, subdivision and construction sites; record and follow up on actions to resolve a breach; provide best practice recommendations; and offer useful tips to facilitate a positive and timely solution.
This checklist has been endorsed by WALGA as a necessary tool in the drive for delivering a Waterwise community and to reduce the environmental impact of urban development.
Local Governments are encouraged to use this checklist as their own “in-house” publication. The Checklist could be included in a manual or as part of your internal reporting processes. It’s simple to do: choose the web-based version of the checklist and add your own logo.
An interactive pdf version of the checklist can be downloaded for use in the field; simply ‘save as’ with the name of the site visit to maintain your records. Download the interactive pdf checklist.
Free On-Site Builders Checklist for Preventing Sediment Loss now available – a handy new tool for your toolbox!
All builders (including sub-contractors, tradespersons & suppliers) must take responsibility for controlling sediment loss from building sites.
The Sediment Task Force’s Builders Checklist can be used as a guide to prevent soil erosion, sediment runoff, sand drift and dust from building sites. This is good news for builders as it will result in:
Builders can use the checklist when arriving at and leaving site, for regular checks of sites and vacant blocks, and before and after a rain, wind or storm event.
The checklist can help builders identify tasks to do immediately to avoid an infringement and/or possible prosecution.
The checklist also contains information on why covering soil and soil stockpiles is the best way to stop erosion and save money and time, and erosion and soil control tips and recommendations.
Building companies can add their own logo to the checklist for inclusion in a work schedule, guideline, manual and/or for reporting purposes. Download docx version here.
There’s also an editable pdf format so builders can fill out the checklist in the field. Download interactive version here using ‘Save As’.
Preventing and controlling soil erosion, sediment runoff and sand drift from building, subdivision and construction sites is a significant issue for Local Governments (LGs). The environmental and financial impacts are considerable, and these are managed by Local Governments across Western Australia in diverse ways to varying levels of success.
In order to raise awareness, educate and inspire LGs to trial and/or embrace new tools and mechanisms to more effectively manage soil erosion, sediment runoff and sand drift, the Sediment Task Force has compiled this case study series Examples of Local Government’s response to erosion resulting from urban development in Perth, WA.
