Statement of Environmental Effects for The Hills Shire DA

A Statement of Environmental Effects for a The Hills Shire Development Application must show how your proposal sits with The Hills Local Environmental Plan 2012 and The Hills Development Control Plan 2012, and how it manages its impacts on neighbours and the surrounding area. Every DA lodged with The Hills Shire that needs consent must include one, and it is the document the council reads to understand your project.

The tricky part for The Hills owners is that the shire stretches from established suburbs like Castle Hill, Baulkham Hills and Kellyville through fast-growing release precincts at Box Hill, Gables and North Kellyville, and on to rural land in the north near the Hawkesbury River. A lot in a growth-area precinct can carry controls that an established street does not, so the wrong assumptions send your SEE off arguing the wrong case.

This guide explains what a The Hills SEE has to cover, 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 The Hills Shire Council requires in a Statement of Environmental Effects
• Which planning framework applies — established LEP or growth-area precinct controls
• Common DA types in The Hills and what each SEE must address
• How to lodge a Hills Shire DA through the NSW Planning Portal
• Who determines your application and when it goes to a planning panel

What The Hills Shire Council Requires in a SEE

Your SEE must address five matters mapping onto the section 4.15 assessment — LEP compliance, DCP compliance, site constraints, neighbour impacts, and the public interest — and growth-area precinct controls add a layer for release lots.

Your Statement of Environmental Effects for a The Hills DA must address five things: how your proposal complies with The Hills LEP, how it meets The Hills DCP, 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 The Hills SEE must address. They mirror the section 4.15 assessment the council runs.

The Hills Shire Council's principal planning instrument is The Hills Local Environmental Plan 2012, supported by The Hills Development Control Plan 2012. The LEP sets your land's zone and the development standards that come with it, such as the maximum height of buildings and the floor space ratio. [VERIFY: confirm the current LEP version and year against the live instrument, as a more recent The Hills Local Environmental Plan may apply; and do not state a specific height, FSR, or setback figure for any zone unless confirmed against the current LEP maps and DCP. Growth-area precincts such as Box Hill and North Kellyville have their own precinct DCP controls.] The DCP then sets the design detail: setbacks, landscaping, private open space, parking, and privacy. Your SEE works through each control that applies and either shows you comply or justifies the variation.

Common DA Types in The Hills and What Your SEE Must Address

The focus of your SEE shifts with the project type — a release-area lot needs precinct DCP controls addressed, while a standard addition in an established suburb centres on overshadowing and privacy.

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

For alterations and additions, your SEE concentrates on building height, setbacks, overshadowing, and privacy from new windows or balconies. For a secondary dwelling, often called a granny flat, the focus is floor area, private open space, parking, and amenity. For a new dwelling on a release lot in a growth-area precinct such as Box Hill or North Kellyville, it addresses the precinct controls, drainage, and lot-specific constraints. For pools and outbuildings, it covers siting, drainage, fencing, and the streetscape. A DA lodgement checklist for NSW helps you gather the right supporting documents for each.

How to Lodge a DA with The Hills Shire Council

You lodge every Hills Shire DA through the NSW Planning Portal — upload plans, SEE, owner's consent, and pay the fee; the council registers it and notifies neighbours before assessment.

You lodge a The Hills DA through the NSW Planning Portal at planningportal.nsw.gov.au, the system every NSW council uses. 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.

• Confirm consent is required by checking your LEP 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

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 Hills Shire Local Planning Panel, and regionally significant development is determined by the Sydney Central City Planning Panel.

Figure 3: Who decides your The Hills DA depends on how significant or contentious it is. Most house DAs are decided by an officer.

For a typical extension, granny flat, or pool, expect a council officer to determine it. The biggest cause of delay is an incomplete application or a SEE that does not address the controls, which triggers a request for more information. The general DA requirements across NSW councils follow the same legislative base, so a complete The Hills lodgement looks much like any other.

Do You Need a Town Planner for a The Hills DA?

For a straightforward residential DA you can prepare the SEE yourself — a town planner costs $600–$1,200 and takes one to three weeks, which is steep for a clearly compliant project on an established lot.

Not always. For a straightforward residential DA in The Hills, 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 release lot governed by growth-area precinct controls, a rural or tree-constrained site, a multi-dwelling development, or one that seeks to vary a development standard such as height or floor space ratio under clause 4.6. For the common residential cases, a well-structured SEE that addresses The Hills LEP and DCP is what you need.
