Statement of Environmental Effects – Strathfield Council NSW

A Statement of Environmental Effects (SEE) is a mandatory planning document that must accompany every development application (DA) lodged with Strathfield Council. Its content is set by Schedule 1, Part 1 of the EP&A Regulation 2021, and the council assesses it against the five-part framework in s 4.15(1) of the EP&A Act 1979.

Strathfield is a compact inner-west municipality — covering Strathfield, Strathfield South, Homebush, Homebush West (Flemington markets), and parts of Greenacre and Belfield — with a planning character shaped by intact Federation and interwar housing, rail and road corridors, and creek flooding in low-lying areas. Getting the SEE right from the start avoids requests for further information and delays.

What Planning Instruments Govern Strathfield DAs?

Every DA lodged with Strathfield Council is assessed against the Strathfield Local Environmental Plan 2012 and the Strathfield Consolidated Development Control Plan, with the legal content floor for your SEE set by the EP&A Regulation 2021.

The Strathfield Local Environmental Plan 2012 (LEP 2012) is a standard instrument plan made under the EP&A Act 1979. It is the primary planning instrument across the Strathfield local government area and governs the fundamental development parameters for every DA — land use zone, maximum building height, floor space ratio, and heritage protections. The LEP 2012 must be the first instrument your SEE addresses.

Beneath the LEP 2012, the Strathfield Consolidated Development Control Plan (Consolidated DCP) provides detailed controls for heritage, residential development, character areas, landscaping, and flooding. Where the DCP and LEP 2012 overlap, the LEP prevails, but your SEE must demonstrate compliance with both layers.

The legal content floor for your SEE is set by Schedule 1, Part 1 of the EP&A Regulation 2021. That schedule specifies the minimum matters a SEE must address for any DA. State Environmental Planning Policies (SEPPs) — including housing and infrastructure SEPPs — may also apply, particularly for sites near the Strathfield, Homebush, and Flemington rail corridors.

The council assesses your DA against the five-part framework in s 4.15(1) of the EP&A Act 1979: the provisions of the applicable environmental planning instruments (including the LEP and any SEPPs), any DCP, the likely impacts of the development, the suitability of the site, and the public interest.

Heritage and Federation Character — the Defining Constraint

Heritage items and conservation areas mapped under the Strathfield LEP 2012 are the single most significant planning constraint across large parts of the municipality — and the most common reason SEEs are returned for further information.

Strathfield's housing stock is defined by intact Federation and interwar streetscapes. The LEP 2012 heritage schedule lists individual heritage items across the LGA, and the LEP 2012 maps heritage conservation areas (HCAs) over broad swathes of Strathfield, Strathfield South, and surrounding suburbs. If your property is listed or within an HCA, your SEE must address heritage significance and demonstrate that the proposed works are compatible with it.

Heritage SEE content in Strathfield typically requires assessment of:

• Heritage significance of the item or conservation area · Front setback alignment with the street pattern · Roof form, pitch, and materials compatible with the period · Scale and bulk relative to adjoining heritage fabric · Impact on the streetscape as experienced from the public domain · Colour and finish palette consistent with period character

Even where a property is not individually listed or within an HCA, the Consolidated DCP contains character controls for residential streets that test similar considerations — bulk, scale, front setback, and roof form — to maintain the wider character of Strathfield's Federation and interwar precincts.

If your property is heritage affected, check the LEP 2012 heritage schedule and the NSW Planning Portal for your address, and engage a heritage consultant early. A Heritage Impact Statement prepared by a suitably qualified consultant is commonly required as a supporting document to the SEE.

Rail, Road, and Acoustic Considerations

Three rail corridors and two major arterial roads create acoustic and air-quality obligations for a significant portion of the Strathfield LGA.

Strathfield sits at the intersection of major rail and road infrastructure. The Strathfield, Homebush, and Flemington rail corridors pass through or adjoin the LGA, and Parramatta Road and Liverpool Road are high-volume arterial roads. For sites within or near these corridors, acoustic noise and vibration — and in some cases air quality — become mandatory SEE topics.

Your SEE must assess whether the proposed use is sensitive to traffic and rail noise (dwellings, accommodation, childcare, and similar uses are). Where noise levels at the site exceed applicable noise criteria, the SEE must identify attenuation measures — glazing specifications, mechanical ventilation, acoustic barriers — and these typically need to be supported by an acoustic report prepared by a suitably qualified acoustic engineer.

For sites on Parramatta Road, the NSW Department of Planning has published specific guidelines on noise and air quality. Your SEE should engage with those guidelines if the proposed use is sensitive to noise or air quality impacts.

Flooding — Powells Creek and Saleyards Creek

Low-lying land near Powells Creek and Saleyards Creek can be subject to flood planning controls — and if your land is flood affected, your SEE must address finished floor levels and flood-compatible construction.

Hazard notice: Flood-affected land in Strathfield is subject to specific LEP 2012 flood planning controls. If your planning certificate (formerly s 149 certificate) shows flood affectation, your SEE must address finished floor levels, flood-compatible materials, and the requirement to avoid any net increase in flood impacts on neighbouring properties. Check Strathfield Council's flood information and the applicable flood study for your catchment before preparing your SEE.

Powells Creek and Saleyards Creek are the primary waterways creating flood risk for low-lying land in the Strathfield LGA. The extent of flood affectation varies by site — some land is within the flood planning area without being in the high-hazard zone, while other land is more severely constrained.

If your site is flood affected, your SEE must address:

• Whether the proposed development is a permissible use on flood-affected land under the LEP 2012
• Finished floor levels in relation to the flood planning level
• Materials, construction methods, and fittings that are appropriate for flood-affected buildings
• Evacuation and access during a flood event
• The requirement not to worsen flood impacts on neighbouring land

Council flood study information is publicly available for the affected catchments. A preliminary check of your planning certificate and the council's flood mapping will confirm whether flood planning controls apply to your site.

Common DA Types in Strathfield

Most DAs lodged with Strathfield Council fall into one of four categories, each with a distinct SEE focus shaped by the LGA's heritage character, creek flooding, and proximity to rail infrastructure.

Understanding which category your DA falls into helps you build a SEE that addresses the right issues in the right depth.

Heritage alterations and additions are among the most common DA types across Strathfield and Strathfield South. The SEE must assess heritage significance, streetscape impact, and the compatibility of the proposed design with the period character of the item or conservation area. A Heritage Impact Statement prepared by a suitably qualified consultant is commonly required as a supporting document.

New dwellings and replacement dwellings require a SEE that addresses building height and setbacks under the LEP 2012 and DCP, character compatibility with the street, privacy and overshadowing impacts on neighbours, and tree canopy obligations. Heritage status must be checked before finalising the design.

Medium-density development near Strathfield or Homebush centres requires assessment of built form, height, density, parking, traffic, and the transition from denser development near the centre to lower-density residential streets. SEPP overlays should be verified for sites near the rail corridor.

Flood-affected sites require a SEE that specifically addresses flood planning controls, finished floor levels, and flood-compatible construction methods — regardless of the development type proposed.

When Does the Sydney Central City Planning Panel Decide?

Most Strathfield DAs are determined by council officers or the Strathfield Local Planning Panel — but larger or more complex applications go to the Sydney Central City Planning Panel.

Strathfield sits within the Sydney Central City Planning Panel's jurisdiction. For DAs with a capital investment value (CIV) above the threshold set by the EP&A Act and relevant Minister's directions, the Sydney Central City Planning Panel — not Strathfield Council — is the consent authority. Certain categories of development (including sensitive development and Crown development) may also be referred to the Panel regardless of CIV.

Where the Panel is the consent authority, your SEE must satisfy the same legal content requirements under Schedule 1, Part 1 of the EP&A Regulation 2021 and s 4.15(1) of the EP&A Act 1979 — but the Panel's processes, pre-lodgement requirements, and assessment timelines differ from council's. Confirm the consent authority for your DA before lodging.
