Assess landscape sites


Application

This unit of competency describes the skills and knowledge required to carry out a landscape site assessment and develop recommendations.

It applies to individuals who analyse information and exercise judgement to complete a range of advanced skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

3.3 Locate structural elements and confirm existing services and facilities

3.4 Record the presence, location and extent of other relevant site constraints

3.5 Sample areas of homogeneous soils and growing media to send for testing and analysis of soil content and contamination as requested by client or as required in the brief provided

4. Determine the impact of development for trees on site

4.1 Obtain the consulting arborist report to assess trees on site

4.2 Determine and record tree protection zones

4.3 Document the impact of proposed development on each tree

4.4 Identify trees that are exempt from approval requirements

4.5 Identify and locate on the site plan trees impacted by development, according to regulations applying in the local jurisdiction

4.6 Include trees identified by the consulting arborist report as requiring pruning or removal in a development application

5. Document a site assessment report
