ENVIRONMENTAL IMPACT ASSESSMENT THE ROLE OF THE ESTATE SURVEYOR AND VALUER ESV, DR. OKORONKWO, NDUKAUBA SUNDAY NWAFOR Department of Estate Management, Imo State University Owerri, Nigeria Abstract: Environmental Impact Assessment is a multi-disciplinary activity which the Estate Surveyor and Valuer must partake in its conduct. It is the study of land to determine if there are any factors such as would possibly give rise to concerns about hazardous materials, protected species, historic remains or other such factors and, a written report containing an analysis of the ecology and construction of projects and after completion and public usages. The components of Environmental Impact Assessment Report are: concerns and points of views of all the various groups interested in, and affected by the projects must be considered throughout the Environmental Impact Assessment processes; hence, developer’s preferred sites of the project with reduced adverse environmental consequence is considered; expose both the viability and liability of the project to the investor; enable competent authority’s response to issues on permit application; expose the implication of projects’ adverse consequences on the other projects which governments may wish to promote; enable competent authority’s response to issues on permit application. Total Economic Values of potential hazards of the projects can only be quantified by the Estate Surveyor and Valuer who is that person permitted by law to value and determines the value of property, chattel, plant and machinery, equipment and any other fixed asset or motor vehicle in Nigeria. Various method of Environmental Valuation is: the Contingent Valuation Method (CVM); Hedonic Pricing (HP) Model and, the Indirect Valuation Method (IVM). Most of the current valuation professionals are yet to embrace the art and science of Total Economic Value valuation and they need to be exposed to further training on this activity. This work hinges on literature hence, bases on narratives of significant issues on the topic.
