PROJECT BRIEF 1.1 Project Description This report is oriented to the road upgrading project under the World Bank-financed Henan Highway Project III in the poor parts of Henan Province. The project consists of 11 components, which are separately described, by code and name, as follows: 1-1 Xiangcheng-Shangcai road from Shangcai County seat to the boundary of Zhumadian and Zhoukou 2-1 Pingyu segment of Zhumadian-Xincai road 3-1 Shilihe-Zhangjiatucheng segment of G312 road 4-1 Guanji-Huabu bridge segment of G106 road 5-1 Zhaowanq bridge-Luoshan County seat segment of Kai-Gong road 5-2 Luoshan County seat-Gongjiapeng segment of Kai-Gong road 6-1 Guangshan-Mafan road 7-1 Shangcheng-Changzhuyuan road 8-1 Xinxian County seat-Hepu road 9-1 Dongjiahe-Tanjiahe road 10-1 Zhengyang road in Zhumadian Prefecture This document is prepared as a supplementary to the IEE, which was completed in November 1999, for these project components except for the last one. Zhengyang road is Luhedian (k266+700) to Dalin (k294+700) in Zhengyang County, Zhumadian Prefecture, covering a distance of 28 km. It is at Grade III in plain areas, with a subgrade width of 7-12 m and a surface width of 7 m. When some segments cut short under the upgrading project, it will have a subgrade width of 12 m and a surface width of 12 m. The before versus after technical grades and cost estimates are shown in Table 1-1. The geographic locations of these roads are illustrated in Maps 1 and 2 attached hereto. 1.2 Project Features The project involves the upgrading of 11 components in rural parts of China. Zhengyang road upgrading will be achieved by widening the subgrade and improving the surface, which will increase the technical grade and capacity of existing road without additional land use and large financial requirements. Therefore, additional land acquisition and resettlement will not be involved in any case. 1.3 Project Schedule Upgrading of this component is scheduled to be commenced in 2000, and completed and put into operation before cr after 2001, i.e. a construction period of 1 year.  Table 1-1 Summary of Road Upgrading Components No. Name Length Existing Road Upgrading Standard lotal Cost Construction Notes (km) Grade Traffic Subgrade Surface Degree of Grade Subgrade Surface Type of ('0000 Period Volume Width (m) Width (m) Congestion Width (m) Width (m) Surface RMB) I Xiangcheng-Shangcai Road 43 III, IV 4317 12 6-7 1.46 11 12 9 Asphalt 4500 2000-2002 Present traffic volume refers to from Shangcai to Boundary standard moderate vehicles in of Zhumadian and Zhoukou 1997. 2 Pingyu Segment of 31 III 2912 16 7 1.38 II 15 9 Asphalt 4500 2000-2002 Present traflic volume refcrs to Zhumadian-Xincai Road daily mixed traffic volume in 1998. 3 Shilihe-Zhangjiatucheng 34 III 2297 16 7 1.33 11 16 12 Asphalt 5040 2000-2002 Present traffic volIme refers to Segment of G312 Road standard moderate vehicles in 1997. 4 Guanji-Huabu Bridge 43 III 1342 16 9 1.19 II 16 12 Asphalt 5400 2000-2001 Present traffic volume refers to Segment ofG106 Road standard moderate vehicles in 1997. 5 Zhaowanq Bridge-Luoshan 1669 16 1.30 11 16 12 Asphalt 1650 2000-2001 Present traffic volume refers to County Seat Segment of standard moderate vehicles in Kai-Gong Road i997. 6 Luoshan County Seat- 49 IV 1699 16 7 1.30 III 16 7 Asphalt 1960 2000-2001 P resent traffic volume relers to Gongjiapeng Segment of standard moderate vehicles in Kai-Gong Road 1997. 7 Guangshan-Mafan Road 32 IV 330 12 6 1.10 III 12 7 Asphalt 960 2000-2001 Present traffic volume refers to standard moderate vehicles in 1997. 8 Shangcheng-Changzhuyuan 45 Unclassified 265 9 5-6 1.02 IV 9 6 Asphalt 900 2000-2000 Present traftic volume rccrs to Road standard moderate vehicles in _______ ~~~1995. 9 Xinxian County Seat-ilepu 48 Unclassified 487 8 3.5 1.22 Unclassified 8 7 Asphalt 2300 2000-2002 Present traffic volume refers to Road standard moderate vehicles in I 1 ~~~~~~~~~~~1995. 10 Dongjiahe-Tanjiahe Road 36 Unclassified 350 9 None 1.01 Unclassified 9 7 Asphalt 2860 2000-2001 Present traffic volume refers to standard moderate vehicles in 1995. 11 Zhengyang Road in 28 III 1078 12 7 1.10 1I 12 12 Asphalt 3590 2000-2001 Present traffic volume relfers to Zhumadian Prefecture standard daily vehicles in 1996 400 33600 l Note: All of the 1 1 segments will be upgraded on the basis of existing roads, not involving any new road, land acquisition or resettlement. 2  2. ENVIRONMENTAL SETTING 2.1 Physio-Environmental Description 2.1.1 Geography and Topography Among the 11 road upgrading components of the project, Zhengyang road in located in Zhengyang County, Zhumadian Prefecture, in the flat and broad southern part of Huang-Huai plain, adjacent to Xincai and Xi Counties in the east, Queshan County in the west, Runan County in the north, and Luoshan and Xinyang Counties in the south. It falls within the inclining plain area of the Dabie Mountain, with gentle slopes and low mounts in the west and alluvial plains elsewhere. The land here declines from northwest to southeast, with an average elevation of 78.8 m. Rivers in this region includes Huai, Ru, Wenshu, Lu, Qingshui, Huangdagang and Tianbai. It generally lowland, flat and open. 2.1.2 Climate Zhengyang component is in Zhumadian prefecture, in the subtropical-temperate transition zone where the continental monsoon climate is characterized by both subtropical and temperate climatic features. There are 4 distinct seasons, including hot summer and cold winter, with the rainy season coinciding with the hot one. According to the long-term meteorological data from Zhumadian Prefecture, the climatic parameters in the project area include: annual average temperature of 14.9
