Wind impact information

Policy 4.5 identifies wind impacts as a matter to address for buildings over 6 metres that require Council approval. The City should identify the information it relies on for this issue.

Applicant's claimEN-0005

The applicant states an overall height of up to about 12 metres

The development summary says court-clearance requirements result in an overall building height of up to about 12 metres above natural ground level.

What this does not prove: “Approximately 12m” is the applicant's stated precision. This note does not independently survey the building height.

Policy 4.5 requires impact information for certain buildings over 6 metres

For buildings over 6 metres that require Council approval under Clause 8.1, Policy 4.5 says the application shall include information addressing amenity, overshadowing, wind impacts, building design, siting, bulk, scale and colour.

What this does not prove: This note records the topics the policy says must be addressed. It does not decide whether the applicant's information is adequate.

Review of the supplied DA file did not identify a wind-impact assessment

Policy 4.5 lists wind impacts among the matters to address for buildings over 6 metres. The recorded review of every page image and transcription in the supplied 47-page DA file did not identify a wind-impact assessment.

What this does not prove: This is a result of the stated review methods within the supplied file, not a finding that unacceptable wind effects will occur. Other material may exist.

Questions worth asking

What wind-impact information did the applicant provide for this building?
Does the City consider that information adequate under Policy 4.5?

CAMPAIGN POSITION

Refuse DA26/1308 in its current form.

Only if approved anyway: If approved anyway, require suitable wind evidence and any controls before construction.
