DRAFT STRATEGIC ENVIRONMENTAL IMPACT ASSESSMENT (SEA) STUDY REPORT FOR THE PROPOSED TATU CITY EXTENSION (MCHANA ESTATE) MASTER PLAN, KIAMBU COUNTY INVITATION OF PUBLIC COMMENTS IN LIGHT of the provisions of section 57 A of the Environment. Management and Co-ordination Act (EMCA), Cap. 387, Regulations 42 and 43 of Environmental (Impact Assessment and Audit) Regulations, Legal Notice No. 101 of 2003, the National Environmental Management Authority (NEMA) has received a Draft Strategic Environmental Assessment (SEA) Study Report for the Proposed Tatu City Extension (Mchana Estate) Master Plan, Kiambu County. The SEA findings are expected to integrate the existing sectoral plans and programs to establish sustainable economic zone development mechanisths. Tatu City Limited is the Plan owner. Tatu City Extension (Mchan Estate) Master Plan will be a large new city redefining the quality and scale of urban development in Kenya, massively reducing congestion in central Nairobi and reverse traffic flows between the centre and Kiambu County. With living and working spaces, communities, schools and hospitals, Tatu City will help sustain and accelerate Africa's economic growth, meet the aspirations of Africa's burgeoning ' middle classes, and serve as a catalyst for further urban development. The specific objectives of the Master Plan are: (a) To develop a housing development with low, medium and high-density units targeting both middle and high-income earners. (b) To establish industrial development that includes light and heavy industries. (c) To develop educational institutions including pre-primary, primary and secondary schools, middle level college, research Centre and university. (d) To designate recreational and sports facilities and services providing various sports and recreational activities with public amenities such as green open spaces. (e) To provide commercial Centre and services with various and mixed-use developments. (f) To design infrastructure and utilities and services with reliable power supply network that includes renewable sources. • (g) To establish a transportation system with a comprehensive road network system that includes transit and local roads. (h) To designate natural green open spaces, wetlands and water bodies. The Strategic Environmental Assessment (SEA) Objectives are: (a) To enhance proper forward-thinking in planning and zonation of the upcoming towns in order to avert the risks and consequences of poorly planned cities. • (b) To identify environmental and poverty-combating priorities and how these may be influenced by the proposed Masterplan. (c) To ensure that conservation of biodiversity is at the core of the Masterplan formulation and implementation. (d) To ensure that the proposed Masterplan is compatible with sustainable environmental planning and management. (e) To ensure the consideration of alternative Masterplan options, including the do-nothing option, at an early stage when an agency has greater flexibility. (j) To enhance the consistency of the Masterplan across different sectors including the Big Four Agenda (Enhancing Manufacturing, Food Security and Nutrition, Universal Health Coverage, Affordable Housing). (g) To support decision-making and incorporate emerging environmental issues into sustainable development of the proposed city. (h) To identify environmental impacts and integrate mitigation measures during Masterplan formulation, and in the process, enhance environmental management. (i) To ensure the consideration of cumulative, indirect, or secondary impacts and other unintended consequences when planning multiple, diverse activities of the Masterplan. (j) To support time-efficient and cost-effective development planning by avoiding the need to reassess some issues and impacts at project level. (k) To inform decision makers by evaluating alternative options that meet the Masterplan's objective(s), while also being the best-practicable-environmental-option(s); (1) To integrate environmental principles into the development, appraisal, and selection of Masterplan's options e.g. selection of green technologies for the city. (m)To provide an early opportunity to check whether the Masterplan complies with county, national and international environmental policy and consequent legislative obligations; Possible Impacts Proposed Mitigation Measures • Ensure limited abstraction of river water. Habitat alteration/loss of agricultural land High generation of solid and effluent waste from residential, commercial and industrial areas Increased demand on water sources/decline in ground water levels/pollution of rivers and earth dams • EIAs to be undertaken for all development activities. • Maintain the proposed green spaces as per the master plan. • Where clearance of natural vegetation is inevitable; ensure replacement with indigenous species in landscaped sections and other green spaces. • Formulation and implementation of a wildlife management plan in collaboration with KWS. • Ensure protection of the riparian environment and establishment of a riparian reserve management plan. • Formulation and implementation of a Biodiversity Management Plan. • Ensure all projects comply with the Environmental Management and Co- ordination (Conservation of Biological Diversity and- Resources, and Access to Genetic Resources and Benefits Sharing) Regulations, 2006. • Adoption of an integrated solid waste management plan through a hierarchy of options that includes reduction at source, reuse, recycling, incineration, composting and land filling. • Implementation of a solid and effluent waste management plan. • Domestic, commercial and industrial waste to be managed separately. • Provide mechanisms to segregate wastes at source to enable recycling. • Provision of transfer stations from where waste will be disposed in designated areas. • Connection to existing trunk sewers in Tatu City. • Pre-treatment of industrial effluent before discharge into sewers. • Undertake EIA for all development activities. • Conduct waste Audits annually and other statutory and non-statutory reports. • Compliance to Environmental Management and Co-ordination (Waste Management) Regulations, 2006 and (Water Quality) Regulations, 2006. • IMplementation of Water Resources Management Plan. • Promote rainwater harvesting. • Promote recycling and reuse of water as much as possible. • Conservative water use in low volume fixtures in buildings. • Use of recycled and harvested storm water in cleaning and landscaping. • Incorporate water accounting systems and metering for all areas. • Pre-treatment of all effluent before discharge into rivers. • Undertake a hydrogeological study in collaboration with WRA to determine the sustainable ground water abstraction levels. • Undertake EIA for all development activities. • Ensure all project comply to the Water Act, 2016 and Environmental Management and Co-ordination (Water Quality) Regulations, 2006. • Institution awareness programmes to conserve energy. • Energy conservation through installation/use of energy efficient appliances/fittings. • Adoption of Green Energy Sources e.g. solar energy, waste to energy projects. • Use of green building designs that allow for passive heating and cooling, and maximum utilization of natural light in buildings. Continually seek avenues for energy conservation as international best practices evolve. Implementation of an Energy Management Plan. Carry out energy audits and ensure all projects comply with the Energy Act, 2019 and its subsidiary legislations. Undertake EIA for all development activities. Ensure adequate tree cover and gardens within developed areas to provide shade and cooling effect. Ensure adequate drainage of the site through drainage works.
