Activity 6

Prepare an EIA - Environmental Impact Assessment

Complete pages 10-11 in the virtual fieldwork booklet for this activity.

Learning Intentions

We will learn to prepare a basic Environmental Impact Assessment (EIA) that assesses the potential consequences of a proposed development in the mangrove forest.

Inquiry Questions;

  • How can an understanding of the biophysical environment in a mangrove forest help inform management decisions?

  • How do geographical tools such as Environmental Impact Assessment (EIA) help people make decisions about human impacts in natural environments?

Introduction

What is an EIA?

"Environmental Impact Assessment (EIA) is the process of assessing the likely environmental impacts of a proposal and identifying options to minimise environmental damage. The main purpose of EIA is to inform decision makers of the likely impacts of a proposal before a decision is made. EIA provides an opportunity to identify key issues and stakeholders early in the life of a proposal so that potentially adverse impacts can be addressed before final approval decisions are made." (Australian EIA Network)

What are EIAs used for?

Environmental impact assessments (EIAs) usually form part of a development application under planning legislation. No major development projects are permitted to proceed in NSW without one. EIA’s are normally prepared by environmental/planning consultants with a background in geography and/or science. Technical specialists provide input to an EIA including hydrogeologists, ecologists, geotechnical engineers, social, visual, acoustic and heritage specialists, amongst others.

What is the development proposal at Bobbin Head?

The proposed restaurant/wedding function centre is to be built in the mangrove forest to the south of the foot-bridge at the southern end of the Bobbin Head picnic area.

The development will provide stunning photo opportunities for couples looking across the water to the National Park behind.

It will involve removing 10 mature mangrove trees from the point, and constructing a building with an expansive deck looking north across the waters of Cockle Creek.

It will be built on piers sunk into the mud to maintain the tidal flow to the forest behind it.

It will be powered entirely by solar energy and will not require power to be connected to the site.

It is estimated that the construction phase will employ 30 workers for 12 months. The centre will then provide locals with up to 10 casual evening and weekend positions.

It will attract many visitors to the Bobbin Head precinct, who will all be required to pay to enter the National Park. This money will be used for environmental protection.

Part 1 - Prepare a precis map

A precis map is a rough sketch map of an area.

Watch this video for a demonstration on how to draw a precis map.

Part 2 - Identify the stakeholders

Stakeholders are any individuals, groups or governments who have an interest in a project or area.

There would be considerable interest in this proposed development, both for and against it, and EIAs take into consideration all perspectives.

List the possible stakeholders in this proposed development on page 10 of your virtual fieldwork booklet.

Part 3 - Impacts

What are the potential impacts on biophysical interactions in the mangrove forest from the development.

You have already completed a flowchart of the consequences of removing trees from a mangrove forest on page 5 of your virtual fieldwork booklet.

Use the information in this flowchart to fill in the potential impacts to each of the spheres on page 11 of your virtual fieldwork booklet.

Part 4 - Final recommendation

Should the development be allowed to go ahead?

Weigh up the case for and against and summarise your final recommendation in one paragraph on page 11 of your virtual fieldwork booklet.
