Project Outcome

Description of Outcome
Progress Toward Outcome All civil works on various roads, footpaths and drains were completed in December 2013. From the completed works, it has been reported that travel time has reduced during peak hours which effectively means reduction in operating costs; there has been a reduction in traffic accidents; Safe pedestrian walkways have been provided around the Nukualofa area. From the completed drainage work, it has already been noted that pooling of water after heavy rains have reduced and duration of pooling reduced at critical spots. Full impact of the project and the outcomes achievement will be assessed as part of the EA's PCR that will now be compiled and submitted to ADB by the EA.
Implementation Progress
Description of Project Outputs
Status of Implementation Progress (Outputs, Activities, and Issues)

Construction of monitoring wells completed in 2010. Regular water testing continues.

Geographical Location Kingdom of Tonga

Summary of Environmental and Social Aspects

Environmental Aspects

The Project is classified as environmental category B. An initial environmental examination (IEE) has been

prepared in accordance with ADB's Environment Policy (2002) and Environmental Assessment Guidelines

(2003), and a summary IEE is attached as Appendix 11. The Government's environmental requirements,

as set out in the Environmental Impact Assessment Act (2003), have also been taken into account.

Consultations with stakeholders were undertaken while preparing the IEE to ensure their concerns will be

adequately addressed and incorporated in the project design

The seven core subprojects are located within Nuku'alofa urban area, where the environment has been

substantially modified. Most of the subprojects are maintenance and rehabilitation by nature. They are all

small, involve minor civil works, and none of them will be located or pass through any protected areas

or ecologically sensitive environment. The road upgrades that consist of resurfacing, widening, and

providing sidewalks will be within the existing rights-of-way, and the drainage components consist of

improvements to the existing drainage system in the CBA. Constructing a new drainage channel leading to a

settlement area has been dropped. Mitigation measures have been formulated to minimize environmental impacts to

insignificant levels. The groundwater quality monitoring will involve installing wells around the project area.

It will produce data necessary for improving conservation of the lagoon and foreshore environment. Limited

land acquisition will be involved, but no resettlement will be required.

Involuntary Resettlement

Of the seven core subprojects, only the Sopu Drainage Channel subproject will involve involuntary

resettlement. ( This subproject was dropped as actual land acquisition came to more than what was envisaged at project design) Widening of the Taufa'ahau Road will be contained within the existing right-of-way. The

Taufa'ahau Road right-of-way is not being encroached upon for commercial or any other purpose. A summary land acquisition and resettlement plan (LARP) is included in Appendix 10, and the short LARP is in Supplementary Appendix F of the RRP. A LARP will be prepared for candidate subprojects that require land acquisition or have resettlement impacts following the guidelines set out in the land acquisition and resettlement framework (refer to Supplementary Appendix G).

Indigenous Peoples The great majority of the population in Tonga is Tongan, with a common culture and language.
Stakeholder Communication, Participation, and Consultation
During Project Design A highly participatory approach was employed to prepare the Project, and consultations with stakeholders were conducted throughout Tonga. The social assessment component was based on (i) 16 workshops that included altogether more than 300 participants on community needs assessment and involved particular interest groups, women, youth, and community leaders, as well as church leaders in 'Eua, Ha'apai, Tongatapu, and Vava'u; and (ii) a socioeconomic survey of 431 randomly selected households in Nuku'alofa. A report on the results of the consultations is given in Supplementary Appendix A
During Project Implementation In designing each sub project component the PIU engages in consultation with the relevant stakeholders so that problems do not arise when the subprojects gets to the implementation stage. Quartely project reports are produced and distributed to the stakeholders as well after the Project Steering committes approval.

Business Opportunities

Consulting Services An international consulting firm (57 person-months of international and 151 person-months of national consulting services) will be engaged as project implementation assistance (PIA) consultants to assist the PMU in overall project management and implementation. The consultants will be recruited in accordance with with ADB's Guidelines on the Use of Consultants by the Asian Development Bank and its Borrowers (February 2007, as amended from time to time) using the Quality and Cost-Based Selection (QCBS) method.
Procurement All civil works will be procured through international competitive bidding procedures (ICB). Procurement of specialized equipment for road and drainage maintenance will be done using shopping procedures.
