Stormwater Management Plan Wollondilly

Sustainable Stormwater Management Solutions for Local Council Approval

“Smart stormwater solutions that balance compliance, sustainability, and practicality.”

Effective stormwater management is crucial for protecting Wollondilly's waterways, natural environment, and community. Development that is not well-planned may risk increased flooding, erosion, and water pollution, and can ultimately result in costly delays, noncompliance, and long-term environmental impacts.

At Harris Environmental Consulting, we develop site-specific Stormwater Management Plans for Wollondilly to help developers, businesses, and government agencies achieve compliance while promoting sustainable growth. We have 20 years of experience across New South Wales, and our use of the scientific approach and practical solutions achieves real-world outcomes.

Why a Stormwater Management Plan is Critical in Wollondilly

A properly formulated Stormwater Management Plan is not merely a regulatory requirement; it is a means to protect both the project and the environment. An area with sensitive environments, creeks and rural landscapes, Wollondilly demands proper planning when creating new developments.

An effective plan will:

  • Reduce the risks of flooding and erosion.
  • Improve water quality before it enters local waterways.
  • Safeguarding biodiversity and local ecosystems.
  • Comply with the Wollondilly Shire Council and NSW legislative requirements.
  • Mitigate delays on project timelines due to environmental non-compliance.

How We Manage Stormwater in Wollondilly

Every site is unique, which is why we develop every Stormwater Management Plan to consider the site conditions, council requirements and your project needs, throughout our process:

  • Site Assessment - We assess the topography, soil, vegetation and hydrology of the site to understand how stormwater flows and is managed on your site naturally.
  • Impact Assessment - We identify the risks to waterways, infrastructure, and the surrounding environment.
  • Proposed Solutions - We propose affordable and sustainable drainage and retention systems, including rain gardens, detention basins, and permeable surfaces.
  • Compliance - We provide options for each recommendation that align with Wollondilly Shire Council's stormwater policies and comply with environmental policies at both the state and federal levels.
  • Support - We provide accessible documentation, information for team construction, and ongoing monitoring support to ensure longevity.

Our goal is straightforward: to provide solutions that are practical and environmentally friendly, taking into account the project's budget and timeframes.

Frequently Asked Questions

Do I need a Stormwater Management Plan for every development in Wollondilly?

If your project will result in the change of land use, an increase in hard surfaces, or an impact on drainage, then yes, it’s likely the Wollondilly Shire Council will require a plan. We can let you know if your project requires a plan and assist you with the process for obtaining approval.

How long does it take you to prepare a Stormwater Management Plan?

The time taken depends on the level of detail involved in the project, as well as site conditions. Most plans can be prepared within 2-4 weeks once we have received site information. If your project is urgent, please let us know and we will endeavour to accommodate your timeframes.

What information do you need to provide me to get started?

In most cases, we will need site plans, details of the proposed development, and whether survey data exists. However, if you aren’t sure, we will help outline precisely what is required.

Are you able to assist even if the council has already refused my plans?

Indeed, we help clients improve their life plans or reports that have been denied or require additional information from the council. We will work with you to find practical solutions to address issues, and we will organise a compliant and professional plan or report for submission.

What is different about your approach, outdoor services and plans?

We can marry technical knowledge with workable solutions on the ground. Our stormwater plans and reports are not just about ticking boxes; they are about delivering stormwater outcomes that benefit projects, the community, and the environment.
