9 SUB-PROJECT PROFILE-PHDAV CHUM Chapter 1 - INTRODUCTION 1. Background Following the 2011 floods in Cambodia that caused widespread damage to infrastructure, the Government of Australia and ADB has approved funding under the Flood Damage Emergency Reconstruction Project (FDERP) to assist the Royal Government of Cambodia (RGC) with implementation of repairs. The Project includes restoration irrigation scheme facilities to be implemented by the Ministry of Water Resources and Meteorology (MOWRAM). During the ADB fact finding mission in January and February 2012, interventions were identified within a framework for structuring project activities and divided into 3 Stages. Stage 3 interventions were to follow the Stage 2 fast-track repairs necessary to repair damaged facilities within the following two dry seasons. The project documents identify Stage 3 sub-projects/contract packages in the Procurement Plan (PP). However the PP was a hastily prepared list of sub-projects requiring interventions with guess estimates of cost (with total cost well above actual funding availability) 1. Thus, a project requirement is for the Stage 3 sub-projects to be confirmed prior to commencing detailed design. 2. Purpose of report A project requirement is for the PIU to select the sub-project based on the selection criteria, and prior to commencing detail design, to submit details of the proposed sub-project together with the sub-projects safeguard classification, to the PCMU for endorsement and to the ADB for no objection. This sub-project profile report concerns the Stage 3 intervention for Phdav Chum sub-project located in Batheay district in Kampong Cham province, which is will consist of the emergency reconstruction of the flood protection embankment. The profile includes a brief description and justification of the sub-project. The Phdav Chum sub-project emergency reconstruction work is included in the PP as Contract No. MOWRAM-CW4 for an estimated final contract value of US$2.13 million including Por Tatres sub-project works. 1 The PP was recently revised and included in the Inception Mission MOU of July 2012 Page 9

10 SUB-PROJECT PROFILE-PHDAV CHUM Chapter 2 - SUB-PROJECT DESCRIPTION 1. Description and history The Phdav Chhum sub-project is not an irrigation scheme but a flood protection dyke that was first constructed in the 1960s, and repaired during the Pol Pot regime and later was rehabilitated under the previous Emergency Flood Rehabilitation Project under ADB support in The dyke which is approximately 17 km long starts at Srah Prinh and ends at the junction with the Cheung Prey district road near Siem Bay. The dyke provides protection to a large area including Skun town (Cheung Prey) and a section of the N6 Highway. The existing dike is about 17 km in length and serves to protect the adjacent community and agricultural and non agricultural land including roads from inundation during flooding from the Mekong River. 2. Flood Damage The embankment that constitutes the Phdav Chum flood protection was damaged in parts by erosion and wave action by the extreme flood events of the last two years (2010 and 2011) but was not overtopped or breached. However, the stability of the embankment matrix is in question and the dyke is in need of overall rehabilitation to ensure continued flood protection to the adjacent area. 3. Location The sub-project area is located near the Commune Kouk Rovieng and is accessible through the rural road network from the right side of National Road No.6 at Phaav market. The village road networks are in good condition from the junction of the national road to the sub-project area. The rural road connects to the dike. See Figures 1 and 2 below. 4. Existing Situation The dike is about 17 km in length, nominally 4 m wide with laterite surfacing, and approximately 4 m height at its highest part and includes 3 culverts with stop logs as well as 2 non return flap valves along its course. Rip-rap protection was provided for about 11 km on the flood side embankment slope. The surface of the immediate area protected by the dike is about 7,000 hectares measured between the dike and the national road No.6, which includes not only the agricultural land but also villages, towns, non agricultural land, and roads Description of the facilities Since its rehabilitation in the year 2002 the dike has not undergone any rehabilitation works and is now in state of disrepair (see Ch.3 section 4 Photos). Page 10

11 SUB-PROJECT PROFILE-PHDAV CHUM a) The upstream slope i.e. facing the flooded area is provided with dry stone riprap with geotextile underneath especially at low lying areas. The existing condition at the slope area is damaged to a varying degree and the stones are dispersed. At the higher ground where dike height is lesser, there are no riprap protections and the dike body has already been eroded. b) There are also locations where the damages of the dry stone riprap are minimal and could be retained but there are damages at mid height, some at the topmost and some with total destruction. c) The geotextile is already torn and damaged by the shrubs and movement of the stones. d) The downstream slope with no provision of grass sodding has been eroded and scoured by the water surface runoff. This condition is almost the same throughout the entire stretch of the dike. e) The crest of the dike is provided with laterite and is thinning out. The edges of the crest of the dike especially at the upstream side are destroyed in many portions of the entire stretch. Holes of various sizes of openings are observed which could extend to the original ground. The same condition is also observed at the crest width of the dike. f) These holes are evidence of damage to some sections of the dyke due to the presence of dispersive soils in the embankment matrix Socio-economic and Agriculture Area The overall area is 7,000 ha as mentioned above of which 3,174 ha are reported to be under agricultural activity (see table below) Beneficiaries / O&M The Phdav Chum sub-project is not an irrigation scheme but a flood protection dyke and the responsibility of its operation and maintenance falls under the responsibility of the MOWRAM and PDWRAM. It is therefore suggested that the participatory preparation of the Phdav Chum sub-project involves collaboration with the PDWRAM and the local authorities including the chiefs of the respective communes and the chiefs of villages as representatives of the communities who benefit from this flood protection scheme. Within this perspective the community development would concentrate it is effort on building the capacity of the PDWRAM and the local administration to operate and maintain the flood protection infrastructure Population Table 1 Community data Commune Number of households (hh) Total Population Number of villages Agricultural area & WS (ha) DS area (ha) Kouk Rovieng Khnar Dambong Phdau Chum Prey Char Control Page 11 Version 1

15 SUB-PROJECT PROFILE_ PHDAV CHUM 4.3. Hydrology The hydrology of the Phdav Chum area is covered by the brief report attached here as Appendix 4. Of particular interest for the FDERP sub-project Phdav Chum is the stage hydrograph which shows the high water level stages. The main problem for the designers is to correlate the hydrological stage datum level with that used for the topographical surveys. Experience has shown that in Cambodia the local people have very good reference marks for flood levels experienced during extreme flood events. The dyke has not been overtopped since it was rehabilitated in Page 15

16 SUB-PROJECT PROFILE_ PHDAV CHUM Chapter 3 - SCOPE OF WORKS 1. Design Approach a) The initial design calls for an addition of 50 cm to the existing crest elevation of the highest portion as shown in the survey to provide adequate free board. The crest elevation has not been overtopped by the flood but due to settlement and erosion the original crest elevation has probably been lowered. Verification of freeboard shall be confirmed at detailed design stage. b) The side slope for the upstream shall be 2.0 horizontal and 1.0 vertical while downstream side slope shall be 1.5 horizontal to 1.0 vertical. Dry stone pitching at the upstream side and grass sodding at the downstream shall provide additional protection. c) The finished grade from the centre of the crest width to each side shall have a slope of 2% to let surface runoff flow to the sides and not stagnate at the centre. d) The limits to the proposed improvements shall be finalized upon completion of the survey plan and profile. e) A walk through shall be undertaken to pinpoint the exact location and delineate the extent of the works to be done. Computations of the quantities shall be based on this activity. Initial staking out of the location of the proposed works shall be also included in the walk through for easier ground identification f) Selection of suitable material for fill is of utmost importance as will be control of compacted fill. The soils in the immediate vicinity appear to be highly dispersive and should be tested prior to selection and avoided if presence of dispersive soils is indicated. 2. Repairs The proposed scope of principle works identified for reconstruction includes the following: a) Stripping of the soil and removal of shrubs b) Embankment construction and compaction to meet the design elevation and section c) Excavation of loose soil materials in holes and backfilling with compaction d) Excavation at toe for the dry stone pitching cut off. e) Removal of stones at upstream slope and restoration according to the design thickness f) Placing of filter and geotextile underneath the stone pitching g) Construction of laterite pavement at crest of dike h) Grass sodding at the downstream slope of the dike Page 16

17 SUB-PROJECT PROFILE_ PHDAV CHUM 3. Cost estimate The cost estimate prepared at this pre-detailed design stage is based on the topographical data and amounts to some US$2.36 million including contingencies, which is more than the US$ 2.13 million of the PP that includes another sub-project in the package. However, the cost will also depend on the walk through described above (design approach (e)). Efforts to minimize the total cost but maintain effective rehabilitation works shall be considered. Major items are the dike embankment and the dry stone riprap. Thus the average repair cost of the emergency reconstruction works are reckoned to be less than US$ 1000 per ha, if the gross agricultural area is taken. Of course this project is not an irrigation scheme as such and the works provide flood protection to a wide area and interests. 4.

19 SUB-PROJECT PROFILE_ PHDAV CHUM Chapter 4 - SUB-PROJECT SCREENING 1. Resettlement There is no evidence of involuntary resettlement impact at this pre-design stage from the proposed repairs to the Phdav Chum. Two solid built rest shelters were identified on the dyke, which have been constructed by the local community. One poses no problem as it is built on piles and adjacent to the dyke top on the inside of the polder and rehabilitation is possible without affecting the structure. The second shelter has been partly built on the dyke and is already affecting use of the dyke as a road. This feature has been noted in the topographic survey and the dyke alignment may be altered to compensate at this location in detailed design. Pushing out the embankment at this point will not require land acquisition as the toe of the revised embankment will be in public land (flood side) Resettlement Impact Categorization Check-list The resettlement impact check-list is included in Appendix 1 and confirms that there are no involuntary resettlement impacts and that the project interventions are within the Category C for resettlement as per the SPS. The screening for resettlement categorization was conducted on the 17 th August 2012 by the national Resettlement Specialist accompanied by other team members including design engineers. Initial screening for involuntary resettlement is to be revisited following detailed design. 2. Environment The Phdav Chum sub-project is not situated in a protected area and there will be no change in downstream impacts. Short term environmental impacts may occur during the construction phase. Pre-flood O&M measures will be maintained or improved by the already established PDWRAM and local authorities. Phdav Chum sub-project was subjected to environmental screening process using ADB s Classification System. Based on SPS 2009, a project category is evaluated by the category of its most environmentally sensitive component, including direct, indirect, cumulative, and induced impacts in the project s area of influence. The subprojects are classified according to the following Categories: 1 Category A. A proposed subproject is classified as category A if it is likely to have significant adverse environmental impacts that are irreversible, diverse, or unprecedented. These impacts may affect an area larger than the sites or facilities subject to physical works. 2 Category B. A proposed subproject is classified as category B if its potential adverse environmental impacts are less adverse than those of category A projects. These impacts are site-specific, few if any of them are irreversible, and in most cases mitigation measures can be designed more readily than for category A projects. Page 19

20 SUB-PROJECT PROFILE_ PHDAV CHUM 3 Category C. A proposed subproject is classified as category C if it is likely to have minimal or no adverse environmental impacts Environmental Assessment and categorization The environmental screening presented in Appendix 2 was used as basis for environment categorization and confirms that the sub-project interventions have minimal or no adverse environmental impacts and may be placed in Category C. Based on the rapid environmental assessment conducted, sensitive areas such as cultural heritage site, protected area, wetland, mangrove, estuarine and buffer zone of protected area are not adjacent or within the project area. During construction, impacts on surface water quality, occupational health and safety, noise and vibration, hazardous driving conditions, poor sanitation and solid waste disposal are expected, however, these are minimal and short term in which mitigation measures can be readily formulated and be implemented. Hence, Phdav Chum subproject should be classified as Category C and therefore as per the ADBs SPS an environmental assessment or preparation of an Environmental Management Plan (EMP) is not required 2. 2 ADB PAM appendix 7 Environmental Assessment and Review Framework Page 20

21 SUB-PROJECT PROFILE_ PHDAV CHUM Chapter 5 - CONCLUSIONS 1. Screening The Phdav Chum sub-project emergency reconstruction works will not change pre flood hydrology and the dyke is existing infrastructure. The sub-project conforms to the FDERP general criteria for selection as provided in the ADB project documents 3, principally it is a flood control structure that has been damaged by the consecutive floods of recent years. However, the sector-specific criteria call for existence of an existing FWUC and since this is not and irrigation scheme as such, this criterion should not apply. Average repair costs will amount to less than $1,000 per ha of gross area (agricultural lands) protected after repairs and following project criteria 4 may proceed without having to verify the economic viability. A sub-project review has confirmed that there are no involuntary resettlement impacts and confirm that the project interventions are within the Category C for resettlement. The Phdav Chum sub-project is not situated in a protected area and there will be no change in downstream impacts. Short term environmental impacts may occur during the construction phase. Pre-flood O&M measures will be maintained by PDWRAM. The project interventions are within Category C for environmental screening. 2. Proposed interventions The proposed interventions described above will be defined in detailed design and based on the topographic survey recently carried out. Typical cross-sections for the proposed embankment works are included here in Appendix 3. 3 PAM Annex 1; Selection Criteria for Sub-projects, March Threshold for average repair costs of US$1,000 per ha; PAM Annex 1 Selection Criteria for sub-projects.
