This document summarizes the Initial Environmental Examination (IEE) report prepared for rehabilitation and upgrading of Moratuwa – Piliyandala (B295) road from Kospalana Junction (2+620 km) to Piliyandala (5+120 km) which extends over a distance of 2.5 km. The project area is located within Kesbewa Divisional Secretariat Division of Colombo District of Southern Province. 2. The Government has requested the Asian Development Bank (ADB) to finance Southern Roads Connectivity Project (SRCP) to improve the overall contribution of road infrastructure and institutional arrangements. The Road Development Authority (RDA) of Ministry of Ports and Highways (MOPH) is the institute that is responsible for developing and maintaining Class A and B roads of the country. Through SRCP the ADB is to assist the RDA to improve the overall contribution of road infrastructure for the development of the country and strengthen RDAs’ institutional arrangements to efficiently manage the road infrastructure. 3. The SRCP intends to improve four roads of class “B” (figure 1.1) under the additional financial loan No.2 of ADB under which rehabilitation and upgrading of Moratuwa – Piliyandala (B295) road from Kospalana Junction (2+620 km) to Piliyandala (5+120 km) will be carried out as one of the subprojects. 4. B295 Road connects two trunk roads; Colombo – Galle – Hambantota – Wellawaya (A002) Road at Moratuwa and Pamankada – Horana (B084) Road at Piliyandala. Moratuwa and Piliyandala are important towns located within Colombo district in terms of both commercial and administrative activities therefore a considerable traffic flow could be observed daily along B295 Road. Though 0+000 to 2+620km section of B295 road has already been improved and upgraded, the rest of the road section from 2+620 to 5+120km is in narrow and dilapidated condition which lowers the transportation efficiency along B295 Road. Therefore improvement and upgrading 2+620 to 5+120km section has been identified as a priority road improvement project by the government. 5. The overall objective of this subproject is to improve the transport efficiency of the Moratuwa - Piliyandala (B295) road and to improve the connectivity between Piliyandala and Moratuwa, which includes upgrading the existing road in to a standard two lane configuration including foot paths, cycle lanes, earth shoulders, parking and bus bays at necessary locations. The subproject will improve the road side drainage and road furniture as well. 6. A feasibility study has been conducted for the road section from Kospalana Junction (2+620 km) to Piliyandala (5+120 km) of B295 Road by Egis Bceom International in 2009. The IEE study included field reconnaissance of the 2.5 km section of road which was conducted during the months of September to December 2012 by the team of expertise led by PIU. Description of the subproject 7. This is a rehabilitating and upgrading subproject of existing B295 road from Kospalana Junction to Piliyandala to two lane facility which will be executed by Southern Roads Connectivity Project (SRCP) with financial assistance from ADB. 8. According to the ADB guidelines and the Rapid Environmental Assessment (REA) Checklist the subproject could be categorized as “Category B” which requires an Initial Environment Examination (IEE). The potential adverse impacts on human population or environmentally important areas are
