Top 5 Common Reasons Landscape Plans Get Rejected by Councils

Few things frustrate built environment professionals more than having a project delayed at council due to issues in the landscape plan. For architects and designers working to tight deadlines, every additional information request can mean missed milestones, stretched budgets, and unhappy clients. Understanding the common pitfalls in landscape documentation can help you avoid them—and keep your projects moving.

Here are the top five reasons councils reject or delay landscape plans.

1. Missing or Incomplete Information

The most basic reason plans are rejected is also the most common: missing details. Councils often receive plans that lack:

• North points, scales, and dimensions.

• Plant schedules with species names.

• Tree locations and protection zones.

  
  

If assessors can’t clearly see what’s proposed, they’ll request more information, adding weeks to your timeline.

Pro tip: Always provide a complete drawing set with a clear legend and notes. Treat it as if you were handing it to someone outside your profession.

2. Non-Compliance with Planning Controls

Every council has its own Development Control Plan (DCP), and missing the mark on these is a fast track to rejection. Common non-compliances include:

• Insufficient deep soil zones.

• Lack of private open space.

• Exceeding maximum hard surface coverage.

• Ignoring tree protection or offset requirements.

  
  

Pro tip: Audit your drawings against the relevant DCP before submission—or have a landscape specialist review them for compliance.

3. Inappropriate Plant Selection

Councils are increasingly focused on resilient, sustainable planting. Common mistakes that trigger rejection include:

• Overuse of exotic or high-maintenance species.

• Lack of canopy trees for shade and heat mitigation.

• Ignoring local biodiversity targets.

  
  

Pro tip: Show intent to align with council’s greening strategies by including locally suitable, low-maintenance species.

4. Poor Coordination with Architectural or Engineering Plans

Landscape plans don’t exist in isolation. If your setbacks, levels, or drainage conflict with the architectural or stormwater drawings, council will send them back.

Pro tip: Cross-check your landscape documentation with the architectural and civil sets before submission. Outsourcing this step can help reduce coordination strain on in-house teams.

5. Lack of Professional Endorsement

More councils—like the City of Sydney—are requiring that landscape plans be prepared or endorsed by an AILA Registered Landscape Architect. Submissions without this endorsement risk delays or outright rejection.

Pro tip: Even when not mandatory, involving a registered professional adds credibility and speeds up approvals.

How to Avoid These Roadblocks

Avoiding rejection is less about producing award-winning drawings and more about producing complete, compliant, and coordinated plans. The fastest way to do this is to:

• Build compliance checks into your workflow.

• Use professional landscape support when needed.

• Treat DA and CDC submissions as strategic investments rather than admin tasks.
