What is Environmental Impact Statement ? An Environmental Impact Statement (EIS) concisely

describes and analyzes a proposed action which may have a significant impact on the environment. The EIS is available to the public for information and comment. An EIS must include:

1. description of the action, including its need and benefits;

2. description of the environmental setting and areas to be affected;

3. an analysis of all environmental impacts related to the action;

4. an analysis of reasonable alternatives to the action;5. identification of ways to reduce or avoid adverse

environmental impacts.

The Environmental Impact of roadsThe environmental impact of

roads include the local effects of highways (public roads) such as on noise, water pollution, habitat destruction and local air quality; and the wider effects which may include climate change from vehicle emissions.

Air Quality

There are three potential sources of air pollution on construction sites. They are:-

exhaust gases from vehicles and machinery

exhaust material from chippers. Dust

Air pollution along Pasadena Highway in Los Angeles, United States

Suggested measures:-Ensure that all vehicles and machinery

are fitted with appropriate emission control equipment, maintained frequently and serviced to the manufacturers‘ specifications.

Smoke from internal combustion engines

should not be visible for more than tenseconds

Noise and VibrationTo ensure nuisance from noise and

vibration does not occur:Fit and maintain appropriate mufflers on

earth-moving and other vehicles on the site.

Enclose noisy equipment.Provide noise attenuation screens, where

appropriate.Advise local residents when unavoidable

out-of-hours work will occur.Minimise air vibrations

Roadway noise is a major source of exposure, particularly from tires

Water PollutionUrban runoff from roads and other

impervious surfaces is a major source of water pollution.

Rainwater and snowmelt running off of roads tends to pick up gasoline, motor oil, heavy metals, trash and other pollutants.

Raw sewage and industrial waste in the

river

Erosion

Many of the measures taken to reduce erosion and sediment run-off are:-

Implement a dust prevention strategy, developed at the project planning stage.

Take dust suppression measures, such as promptly watering exposed areas when visible dust is observed.

Install wind fences wherever appropriate.

Erosion Control Mats:The mat reinforces and anchors the root zone of the plant.

Economical ActivityIn most communities, highway bypasses have

little adverse impact on overall economic activity:-

Understand that bypasses are generally beneficial, with few adverse economic impacts.

Small communities need to develop and market themselves as “destinations” to minimize adverse economic impacts from a bypass.

Bypasses will create a number of changes and issues to a community that should be addressed proactively.

Landscapesis to set down minimum

landscape design standards for all projects undertaken on road corridors

A minimalist approach to planting provides

open views and helps emphasise

the landform and the sweeping road

alignment.
