It identifies adverse environmental and social impacts which might be caused by the projects selected for implementation in these settlements and develops, where required, suitable mitigation measures. Environmental measures are described in the present document, while social issues (physical or economic displacement of persons, compensation issues) are dealt with in the RAP, which is a separate document. The ESIA report is based upon the previously submitted and approved reports related to works carried out in Mombasa municipality: Socio-economic report: based on survey works carried out in each of the settlements. Conceptual design report: which includes a preliminary environmental and social screening report as well as a community consultation report. Draft Settlement Upgrading Plan report (Feasibility study): which includes a cost benefit analysis to the choice of variants in which environmental and social parameters are taken into account. Detailed Design report: which is being prepared simultaneously to this ESIA and includes the final design of the infrastructure components. The civil work components taken into account in this ESIA are presented in the following table. Settlement Scope of works 1.
