EXECUTIVE SUMMARY A. Introduction 1. The Haidong City Government (HCG) of Qinghai Province, People’s Republic of China (PRC) has requested the Asian Development Bank (ADB) to provide investment and technical assistance support for the Qinghai Haidong Urban-Rural Eco Development Project. The project will help the HCG to support improvements to the functions and values of Huangshui River and its watershed, including managing flood risks, improving water quality and availability, and increasing climate change resilience. The project will involve river embankment improvements along the Huangshui River, wetland and forest area restoration and rehabilitation, expansion of a landfill facility, reuse of wastewater to irrigate forested areas, and construction of water treatment plants and supply infrastructure to support the planned urbanization in Ping’an and Ledu Districts of Haidong City. 2. Haidong City is a city of 1.72 million residents. Urban development is concentrated in two districts – Ping’an and Ledu. Both districts are located along the Huangshui River, a nationally important tributary of the Yellow River. Urban development in Ping’an and Ledu is concentrated within the narrow valley of the Huanghsui River, and confined between steep mountainous areas. Buildable land is limited and the fertile valley has been experiencing a high rate of conversion from farmland to urban development. According to the Master Planning of Haidong Urban Area (2013-2030), the two districts are expected to add more than half million residents by 2030. Ledu District is projected to increase from 109,800 residents to 502,000 between 2012 and 2030, while Ping’an is expected to see its population grow from 68,100 to 190,000 during the same period. This will put pressure on an already fragile landscape that is prone to flooding and considerable amount of soil erosion, as well as on existing municipal services including water supply and solid waste disposal. B. The Project 3. The proposed project will include four main components: (i) integrated flood protection infrastructure; (ii) urban catchment soil erosion control; (iii) rural water supply and urban solid waste infrastructure; (iv) project management capacity strengthening. The components are summarized in Table I.1. 4. Flood protection will be enhanced by a program of embankments along the Huangshui River and its tributaries to improve water flow and increase flood protection capacity. The river sections will also have rehabilitated riverbanks. Riverbank improvements will be through the development of embankments as landscaped habitats and recreational areas, and wetland construction. Urban catchment soil erosion control will be achieved by irrigated shelterbelt plantations, partly using recycled treated wastewater from the Ping’an WWTP to reduce pressure on limited freshwater resources. The rural water supply infrastructure focuses on the water supply from two existing reservoirs (Fatai and Wenzukou) to be piped to small local WTPs to service the local villages in the upper Qijiachuan valley and then routed through a larger WTP to provide treated water downstream. The solid waste infrastructure is centered on the existing Ledu landfill, which will be rehabilitated and extended. The location of the main project components are shown on Figure I.1. 1 Figure I.1: Overview of project components 2 Table I.1: Summary of Project Outputs and Construction Components Name Description Output 1: Integrated flood management infrastructure for Huangshui River provided 1.1 Huangshui River Channel Ping’an River section rehabilitation and flood protection works along the Segment Huangshui River Channel Ping’an Segment, including 14.68 km of embankments along the main channel, 6 km of embankments along tributary mouths and 100,000 m3 of riverbed blockage removal. 1.2 Huangshui River Channel Ledu River section rehabilitation and flood protection works along the Urban Area Segment Huangshui River Channel Ledu Urban Area Segment, including 15 km of embankments along the main channel,
