The development objective of the Nairobi Metropolitan Services Improvement Project for Kenya is to strengthen governance and services delivery in the Nairobi Metropolitan region and result in improved services delivery benefiting the population of the region, majority of who in the lower income segment are female. Negative impacts include: water contaminations from effluents from construction machinery, contamination include oil leaks and fuel leaks; loss of vegetation through stripping of top vegetation; soil erosion and destabilization of soil structure; and atmospheric pollution by dust particles due to construction activities in the area.
Mitigation measures include: 1) proper servicing of machineries on site according to manufactures details, proper liquid waste collection system should be provided on site, stabilizing lagoons could be constructed to hold waste water before releasing into the river, and Influx of heavy trucks and machinery in the area could cause nuisance, noise, dust and destruction of roads; 2) minimizing vegetation stripping to sites where civil works are to be conducted, re-vegetation of site after civil works with complete reinstatement of the site to better status; 3) thorough vegetation of the sites after completion of the civil works, proper burning of loss areas with gabions and mesh to limit the quantity of top soil lost by runoff; and 4) regular wetting of the working area to control dust, provision of personal protective equipment (PPE) to workers to avoid exposing them to gaseous pollutants.
