PAST PROJECTS

Oxleyan Pygmy Perch Habitat Regeneration

Client: Richmond Valley Council

GeoLINK were engaged by Richmond Valley Council (RVC) to prepare a Statement of Environmental Effects (SEE) with respect to a proposed Evans Head Stormwater Improvement and Oxleyan Pygmy Perch (OPP) Habitat Regeneration Project.

The OPP is a small freshwater fish listed as “endangered” under the NSW Fisheries Management Act 1994 and the Commonwealth Environmental Protection and Biodiversity Conservation Act 1999. The OPP has a very limited distribution confined to the north-eastern coast and south-eastern Queensland and has been recorded within the wallum heath communities that surround the urban area of Evans Head.

The objectives of the Evans Head OPP Habitat Regeneration Project are to:

  • Design urban and roadside habitat regeneration works that ensure OPP habitat is not adversely impacted by stormwater runoff from the existing and proposed urban and industrial areas of Evans Head;
  • Design stormwater improvement works that provide conventional stormwater drainage functions and treatment, whilst protecting the habitat of the endangered OPP; and
  • Provide council with a plan for providing a cost effective stormwater management system

The proposed works involve a range of stormwater management initiatives including education and the design of infiltration devices planted with native vegetation. A detailed analysis of the recommended stormwater strategy was undertaken using the computer models MUSIC and DRAINS to model the treatment effectiveness and hydraulic capacity of the proposed measures.
