Introduction There are 34 villages, 12 schools and 2 hospitals located with in lOOm along Weinan-Tongguan Expressway. Due to the occupation of the Row, 10 villages will be partially relocated. Which are marked with * in Table 2-1, and Taoxia Hospital and Xiaoquan Primary School will be entirely resettled. By 1999, some sensitive areas/buildings will be affected because of noise exceedance. Several kinds of noise mitigation measures will be undertaker. The measures include: 660m noise barriers for 3 areas. 1780m heighten walls for 8 areas and 550m forest belt for 6 area. The mitigative measures structure shown in attached figure. For the areas where noise exceedance occurs in the far future of operational stage, see Table 3-1,3-2 and 3- 3, appropriate measures will be undertaken depending on the actuarial noise exceedance. The noise level should be measured one year before the action year. 2.Prediction Results of Sensitive Sites The sensitive sites noise level at first row buildings along roadsides are presented in Table 2-1 and 2-2.
