Bushfire Hazard Assessment
- - - Subdivisions
    - Whenever a boundary is altered (made smaller or changed) in a residential or rural residential area planning controls for subdivision is required (if two or more existing lots are consolidated this is not considered a subdivision).

  - - Rezoning Reports
    - Bushfire Assessments are prepared as part of a rezoning in a bushfire prone area.

  - - Infill Development
    - An Infill Development involves new house, alterations and additions in pre-existing subdivisions.

- - - Special Fire Protection Purpose Developments
    - Any proposals involving schools, hospitals, bed and breakfast accommodation, eco-tourism, housing for older people, retirement villages, childcare centres, music festivals are considered particularly vulnerable during bushfires and are therefore required to meet some specific requirements. In particular, an emergency/evacuation plan is considered an important component of the strategy to plan for any bushfire risk. The consent authority is the local council but only after the RFS has issued a BUSHFIRE SAFETY AUTHORITY.

    - Check your 149 certificate to see if you need a Bushfire Attack Level (BAL) risk assessment.

Water Cycle Management Studies

Water Cycle Management Studies addresses the integrated management of stormwater, wastewater and erosion and sediment control for the specific type of development proposal. In the context of the Sydney Drinking Water Catchment the WCMS needs to show that the proposed development and management measures can achieve a Neutral or Beneficial Effect (NorBE) on water quality. For other locations outside of the drinking water catchment, the WCMS may be more focused on stormwater quality or soil and water management.

Harris Environmental capabilities include:

WCMS's are reports required for development within the Sydney Drinking Water Catchment. The WCMS must meet WaterNSW criteria for a Neutral or Beneficial Effect (NorBE) on water quality, as required under the State Environmental Planning Policy (Sydney Drinking Water Catchment) 2011. The reports need to be supplied with a development application, with the details to be included depending on the type and scale of development. Typically these assessments will address:

Stormwater management
On-site wastewater
Erosion and Sediment Control / Soil and Water Management

The level of detail required depends on whether your development falls under Module 1, 2, 3 or 4. Once this has been established, can can prepare the report to meet the requirements. For example, a Conceptual Erosion and Sediment Control Plan is required for all new dwellings with construction area >250m², MUSIC stormwater quality modelling and a Soil and Water Management Plan are required for all types of development with more than 2500m² of impervious area.

These studies will be needed for sewered and un-sewered residential subdivisions (more than 4 lots), townhouse developments, extractive industries, car parks, commercial buildings and intensive agriculture and horticultural development where these impervious areas are exceeded.

Recent Projects

Wastewater Transfer Centre

Commercial developments like the one shown in the image, will require a Watercycle Management Study to demonstrate the required stormwater treatment. In the example shown storm water from the exterior hard stand surfaces needed to be treated by biotension basin, sediment basin and constructed wetlands. Where as the wash down water from the putresible waste management system required an anaerobic treatment system followed by constructed wetland.

A Water Cycle Management Study was prepared for a proposed prayer hall and cemetry with on-site wastewater management facilities.

Proposed Boarding House

With limited soil depth and available land, this project needed an Aerated Water Treatment System and 4 sand mounds.

SYDNEY OLYMPIC PARK – LAKE BELVEDERE

The 34m2 floating wetland was positioned to surround half the island (2 x 4m x 4m) and placed as close as possible to the eroding bank to allow roots to bind into the submerged sediment and dampen the currents that are eroding the island.
