National Environment Management Authority (NEMA) has received an Environmental Impact Assessment Study Report for the above proposed project. The proponent, Lone Tree Limited got an approval from Nairobi City County and NEMA to construct a high end office block along Limuru Road on L.R. 21/1/22, Westland Sub-county in 2016. However, passing through the private property, is a narrow seasonal stream akin to a natural drainage that carries (drains) storm water (surface run off) during wet periods parallel to the road to empty to Rui Ruaka via an existing drainage outfall along the main Limuru Road which is a 600 mm diameter pipe culvert. The culvert is about 500 metres from the Lone Tree's property. The surface run off flows through the boundary of Lone Tree property close to the road and they mainly occur and are enhanced by precipitation upstream during rainy season. In order to allow the Lone Tree Limited to develop the office block in a standard way, the surface run off needs to be controlled by training the seasonal stream passing on the property to a functional storm water drainage that direct flow to its natural course downstream while maintain the stream characteristics. The following are the anticipated impacts and proposed mitigation measures: Instream Works Phase Impacts Dust and other emissions(He alth hazard, degradation of Air quality and visual obscurity Water quality along the seasonal stream Riparian degradation Area of Concern Solid wastes on the trained drainage's channel (Pollution and nuisance, choking and blockage of the drainage channel water bodies such as Rui Ruaka Wastewater and sewerage (Health hazard, degradation of Rui Ruaka stream) Water quality down stream effluent from office block finding its way into the stream Potential mishap in operation and maintenance (Due to lack of proper maintenance of trained stream and associated infrastructure) • Sprinkle water on all dust-active areas to suppress dust. • Pave or apply non-toxic soil stabilizers on all unpaved access roads and parking areas. • Cover all trucks hauling soil, sand and other loose materials. • Provide all construction workers with PPE. • Strictly enforce on-site speed limit regulations. • Avoid excavation works in extremely dry weathers. • Have bio-latrines onsite for safe collection of sewage and wastewater respectively from the construction workers. • Properly use and clean sanitary facilities daily. • Undertake engineered approaches to reconstruct riparian system on the 120 metres channel designed to blend in with the local environment. • Ecology restoration and landscape restoration and creation of a minimum 6 metres riparian from both sides of the trained stream. Operation and Functioning Phase Mitigation Measures • Covering of the trained water conveyance channel. • Regular cleanup of drainage trenches within. • Collect and dispose-off solid wastes from the site/office daily. • Ensure source separation and collection of wastes into recyclable and non-recyclable wastes by installation of double waste collection bins at each collection point. • Environmental education for the occupants of the office block. • The office block be connected to an existing sewer system. • Conduct regular checks to detect and correct sewage pipe blockages, damages and leakages. • Location of the trained stream channel be on non-building areas for easy access and monitoring of flow. • Implement an appropriate re-vegetation programme along the stream. • Regular maintenance of defective slabs covering the trained 120Metres conveyance channel from wear and tear that may cause accidents to occupants of the office block and visitors. • Inspection of the trained stream should be carried out regularly to ensure that the systems operate properly.
