Habitat Landscape Architects have a strong environmental bias being experienced in a wide range of environmental and spatial planning aspects. We have successfully completed a diverse range of environmental projects from large scale strategic planning to local site-scale rehabilitation projects.

Some of the environmental services we provide include:

  • Large scale strategic and environmental planning
  • Rehabilitation frameworks, plans and management plans
  • River rehabilitation and stabilization
  • Open Space Planning
  • Site and Environmental Management Plans
  • Ecological Storm Water Management Plans
  • Water-sensitive urban design
  • Site Assessments and Specialist Environmental Attribute Mapping
  • Feasibility studies
  • Ecological design solution

APIES RIVER

As early as 2001 the City of Tshwane Metropolitan Municipality (CoT) recognized the  crucial  need to rehabilitate the  Apies    River north  of the Wonderboom Poort up to the inlet of the Bon Accord Dam on account of the constant flooding of existing    approved  developments and ecological degradation of the overall system. Habitat Landscape Architects were appointed in 2010 to develop a Rehabilitation Framework for the Apies River from the Wonderboom Poort to the Rosslyn Bridge. The principle purpose of the rehabilitation framework was to integrate the hydrological model and design with the ecological restoration and rehabilitation of the Apies River.

The key goals set for the restoration of the river included the following:                                                                   

• Assist the River to reach a state of equilibrium

• Improve the natural resources quantitatively and             qualitatively   

• Restore and protect the river corridor and associated       habitats     

• Increase biological diversity

• Maintain river corridor connectivity   

•  Maximise recreational and open space use

•  Encourage individual and collective stewardship of          the river
 
Through a number of reiterative design cycles the ecological and recreational design requirements for the proposed rehabilitation   project were refined and integrated with the hydrological model and design from the Institute for Water and Environmental Engineering (IWEE) of the Department of Civil Engineering, University of Stellenbosch, in order to develop a framework that will inform the detail design phase.


The broad process included:                                              • Identifying a reference stream corridor and                       determining  the  desired state of the River

• Undertaking a detailed vegetation survey

• Mapping of important vegetation, river features and         the opportunities, constraints and habitats that the         design will have to respond to

• Reviewing the ecological compatibility and identifying     possible  conflicts in the detailed hydrological                 engineering model.


The Rehabilitation Design Framework was developed from a combination of baseline assessments as well as best-management practice in stream corridor restoration.
