Statement of Environmental Effects for a Sutherland Shire DA

A Statement of Environmental Effects for a Sutherland Shire Development Application must show how your proposal sits with the Sutherland Shire Local Environmental Plan 2015 and the Sutherland Shire Development Control Plan 2015, and how it manages its impacts on neighbours and the surrounding area. Every DA lodged with Sutherland Shire Council that needs consent must include one.

Sutherland Shire is one of the most constrained residential areas in Sydney. The Shire wraps around bushland and the Royal National Park, so large parts of it are bushfire prone. It has long water frontages on Port Hacking, the Woronora and Georges Rivers, and the Cronulla coast, so foreshore and coastal controls apply widely. Low-lying land carries flooding and acid sulfate soils. A SEE that ignores these gets stalled with a request for more information.

This guide explains what a Sutherland Shire SEE has to cover, the constraints that shape it, the common DA types in the area, how to lodge with the council, and whether you need a town planner.

In this guide, you will learn:

• What Sutherland Shire Council requires in a Statement of Environmental Effects
• How bushfire, the coastal foreshore, flooding and acid sulfate soils shape your Sutherland Shire SEE
• Common DA types in Sutherland Shire and what each SEE must address
• How to lodge a Sutherland Shire DA through the NSW Planning Portal
• Who determines your application — officer, Sutherland Shire LPP, or State panel

What Sutherland Shire Council Requires in a SEE

Your SEE must address five matters under section 4.15 — LEP compliance, DCP compliance, site constraints, neighbour impacts, and the public interest — with bushfire, coastal protection, flooding, and acid sulfate soils each potentially decisive depending on your location.

Your Statement of Environmental Effects for a Sutherland Shire DA must address five things: how your proposal complies with the Sutherland Shire LEP 2015, how it meets the Sutherland Shire DCP 2015, the constraints on your specific site, the impacts on your neighbours, and the public interest. These map directly onto the matters a council must weigh under section 4.15 of the Environmental Planning and Assessment Act 1979.

Figure 1: The five matters a Sutherland Shire SEE must address. They mirror the section 4.15 assessment the council runs.

Sutherland Shire Council's principal planning instruments are the Sutherland Shire Local Environmental Plan 2015 and the Sutherland Shire Development Control Plan 2015. The LEP 2015 is a standard instrument plan made under the EP&A Act 1979 and applies LGA-wide, having superseded the former Sutherland Shire LEP 2006. [VERIFY: do not state a specific height, FSR, setback, or flood planning level for any Sutherland Shire zone unless confirmed against the current Sutherland Shire LEP 2015 maps, the Sutherland Shire DCP 2015, and the council's bushfire, flood and acid sulfate soil mapping.]

The Bushfire, Coast, and Flood Constraints Your Sutherland Shire SEE Must Address

Sutherland Shire's combination of extensive bushfire prone land adjacent to the Royal National Park, long coastal and river frontages on Port Hacking and the Georges River, and low-lying land carrying flooding and acid sulfate soils means the site constraints section of your SEE does heavy lifting.

The constraints in Sutherland Shire are the constraints of a bush-and-water landscape, and your SEE has to confront the ones that touch your land.

Figure 2: The constraints that shape a Sutherland Shire SEE. Bushfire, flooding, and acid sulfate soils are flagged as hazards.

Large parts of the Shire are mapped as bushfire prone land because of the surrounding bushland and the Royal National Park, which brings Planning for Bush Fire Protection into play and can require a bushfire assessment. The water frontages on Port Hacking, the Woronora and Georges Rivers, and the Cronulla coast carry foreshore building lines and coastal controls, including the State Environmental Planning Policy (Resilience and Hazards) 2021 for coastal management. Low-lying land near rivers and estuaries floods, so floor levels and safe access matter, and the same low-lying land is often mapped for acid sulfate soils, which needs a management plan if soils are disturbed. Heritage items, conservation areas, and biodiversity values are also listed and mapped under the LEP 2015. Check the NSW Planning Portal spatial viewer for what touches your site.

Common DA Types in Sutherland Shire and What Your SEE Must Address

The focus of your SEE shifts with the project type and the constraints on your lot — bushfire prone and foreshore sites need those issues addressed upfront, while a standard addition on unconstrained residential land centres on overshadowing and privacy.

Most residential DAs lodged with Sutherland Shire Council fall into a handful of types, and the focus of your SEE shifts with each one.

Figure 3: The four most common Sutherland Shire DA types and where each SEE puts its weight.

For alterations and additions, your SEE concentrates on height, setbacks, overshadowing, and privacy to neighbours. For a secondary dwelling, often called a granny flat, the focus is floor area, private open space, parking, and amenity. For a dual occupancy or medium-density development, it addresses density, built form, deep soil and landscaping, privacy, and parking. For pools and outbuildings, it covers siting, drainage, fencing, and the streetscape, plus bushfire and foreshore setbacks where they apply. A DA lodgement checklist for NSW helps you gather the right supporting documents for each.

• Confirm consent is required by checking your LEP 2015 zone and land use table
• Prepare plans, SEE, owner's consent, and BASIX certificate where needed
• Lodge on the NSW Planning Portal and pay the DA lodgement fee
• Respond promptly to any council requests for additional information
• Await council assessment against section 4.15 and the determination

How to Lodge a DA with Sutherland Shire Council

You lodge every Sutherland Shire DA through the NSW Planning Portal — upload plans, SEE, owner's consent, and pay the fee; the council registers it, notifies neighbours, and assesses it against section 4.15.

You lodge a Sutherland Shire DA through the NSW Planning Portal at planningportal.nsw.gov.au, the system every NSW council uses, and DAs must be lodged online there. You upload your plans, owner's consent, supporting documents, and your SEE, then pay the fee. Our step-by-step guide to lodging a DA in NSW covers the portal mechanics.

Once lodged, the council registers your DA, notifies adjoining owners where required, and assesses it against section 4.15. Most straightforward residential DAs are decided by a council officer under delegated authority. More contentious or significant applications go to the Sutherland Shire Local Planning Panel, and regionally significant development is determined by the Sydney South Planning Panel. The general DA requirements across NSW councils follow the same legislative base, so a complete Sutherland Shire lodgement looks much like any other once you are working from the right plan.

Do You Need a Town Planner for a Sutherland Shire DA?

For a straightforward residential DA on unconstrained land you can prepare the SEE yourself — but bushfire prone lots, foreshore sites, flood-affected or acid-sulfate-soil land are where a specialist earns their fee.

Not always. For a straightforward residential DA on an unconstrained, sewered lot, such as a single-storey addition, a granny flat, or a pool, you can prepare the SEE yourself or use a service rather than engaging a town planner. A traditional town planner in NSW typically charges $600 to $1,200 and takes one to three weeks, which is a lot for a clearly compliant project.

You are more likely to want a planner where the project is complex: a bushfire prone lot near the Royal National Park or other reserves, a foreshore site on Port Hacking or one of the rivers, a flood-affected or acid-sulfate-soil lot, a heritage item or conservation area, or a proposal that seeks to vary a development standard such as height under clause 4.6. For the common residential cases, a well-structured SEE that addresses the current Sutherland Shire LEP 2015 and DCP 2015 is what you need.
