Appendix 1. Decision Letter by MONREC The Government of the Republic of the Union of Myanmar Ministry of Natural Resources and Environmental Conservation Union Ministry Office Registered No. (Forestry)- 3/(2)/16 (Gagyi)(1288/ 2018) Date: 2018, April (19) Subject: Confirmation for (ECD) comment/remark on ProJect Categorization Proposal for Rural Road Development ProJect funded by ADB loan in Magway region and Ayarwaddy region. Reference: (1) Letter no., 173/ International- law/ ADB/ 2018 of Rural Road Development Department of Ministry of Construction, dated 15 March 2018 (2) Letter no. EIA- 1/ 7/ (452 (Fa)/ 2018 of Environmental Conservation Department dated 4 April 2018 According to Minister remarked on Submission letter (reference-2) for ECD comment on ProJect Categorization Proposal for Rural Road Development ProJect funded by ADB loan in Magway region and Ayarwaddy region, it is informed that the comments on ProJect Categorization Proposal for Rural Road Development Project is confirmed in accordance with the reference letter (2) submitted on 4th April 2018 x x x x x For Union Minister Win Zaw, Deputy permanent Secretary Director General Environmental Conservation Department Copy to - Ministry of Construction Appendix 2 Types of Paving Considered for RRAP Flexible Pavements - DBST Code Description Typical Application and Features DBST Type 1: Open Field Areas and Suitable for open field areas and flat terrain. Flat Terrain Theoretical elevation of road center line above the existing terrain guided by approximate geometry of MOC Rural Road Type (B) Standard Design. (See Annex I). Diagram in Annex II provides the road designer necessary guidance of how to establish the proposed levels of the road centerline in a step by step manner. Key features of this cross section are: • Nominal paved width of carriageway = 12’ (or rounded to 3700 mm in metric system). • Shoulder width as per MOC Rural Road Type (B) = 4’ (or 1150 mm in metric system). • Nominal crown width 20’ (or rounded to 6000 mm in metric system) • Camber and shoulder cross fall = 3% In most cases under the prevailing conditions in both regions it will neither be necessary or possible to construct side drains for cross sections in open field areas because the terrain is predominantly flat. However in some specific cases side drains are needed. If applicable these side drains should be constructed at a distance of not nearer than 7000 mm from the road centerline and the site engineer has to set-out drain levels during implementation through a detailed survey to ensure the drains are built at a self-draining gradient, normally not less than 1%. DBST Type 2: Open Field Areas and Suitable for open field areas and flat terrain with Flat Terrain – Including significant oxcart traffic in Magway Region. Oxcart Tracks (left & Establishing of levels in same manner as Type 1 right) Cross Section. Key features are: • Carriageway, shoulders and slope as Type 1. • Provision of a 10’ (or 3000 mm in in metric system) wide oxcart track at foot of slope. DBST Type 3 In Areas of Limited Suitable for narrow village areas with possibility of (MSD) Space and with constructing open self-draining side drains in stone provision of Masonry masonry works. Side Drains Key features are: • Nominal paved width of carriageway = 12’ (or rounded to 3700 mm in metric system) as Cross Section Type 1. • Shoulder width variable form minimum 500 mmm to maximum 1150 mm depending available space. • Outside dimension of masonry side drains 800 mm deep and 1000 mm wide • Range of resulting formation width therefore variable from min. 6700 mm to max. 8000 mm. DBST Type 3 In Areas of Limited The second option of building lined side drains is by (RCSD) Space and with construction in Reinforced Concrete (RC). This is provision of Reinforced more expensive than drains constructed in stone Concrete Side Drains masonry but may be necessary if: a) There are no high quality masonry stones are available in the area or, b) The drains have to be covered with concrete slabs because direct access by vehicles to the adjacent premises is required (e.g. parking lot in front of a store, loading area for a granary etc.) Otherwise similar features as Cross Section Type 3 (MSD) apply with following key features: • Nominal paved width of carriageway = 12’ (or rounded to 3700 mm in metric system) as Cross Section Type 1. • Shoulder width variable form minimum 250 mmm to maximum 1150 mm depending available space. • Outside dimension of concrete side drains 600 mm deep and 650 mm wide. • Range of resulting formation width therefore variable from min. 5500 mm to max. 7300 mm. DBST Type 3 In Areas of Limited In cases of where it is not possible to construct side (RW) Space and with drains due to low longitudinal gradients a space provision of Retaining saving option could be the provision of small Walls retaining walls and reducing shoulder widths. Key features are: • Nominal paved width of carriageway = 12’ (or rounded to 3700 mm in metric system) as Cross Section Type 1. • Shoulder width variable form minimum 250 mmm to maximum 1150 mm depending available space. • Approximate outside dimension of masonry retaining wall of max. 1000 mm high and 650 mm wide. • Range of resulting formation width therefore variable from min. 5100 mm to max. 7300 mm.

High potential for application in cases of where the building high embankments is considered not desirable or on existing roads with large areas with existing stable road base. Theoretical elevation of road center line for vertical alignment design purpose we assumed in range of 200 mm to 300 mm above the present existing surface. However
