Environmental impact assessment (EIA) is a decision making process to analyze environmental impacts. this paper is related to eia of proposed six kilometer road from kalishuri to surjomoni union at bauphal, patuakhali that conducting by local government and engineering department (lged). The proposed area is so far behind to good communication facilities within the different parts of this region due to absence of road connecting to other area. The significance of the proposed road involves directly to the people of that region in developing their social, economic and environmental condition. the aims of the study are to find out the potential environmental impacts, mitigation measures and to compute the environmental impact value (eiv) of the project. the key findings of this study include environmental positive and negative impacts mainly decreasing plant biodiversity, hydrology and agricultural lands. The study reveals that the eiv is-1 (negative one) in regarding to three environmental factors named ecological, physico-chemical and human interests. The mitigating options of various impacts on the project are environmental friendly technology, conservation of road side plantation, agricultural lands etc. the eia helps to complete an environment friendly project by providing sound management on environmental impacts and means of preventing or reducing those impacts.
