SITE SPECIFIC MITIGATION PLAN – N6

Kien Phong Pagoda



Road section from Km 5+220 to Km 6+365





ATTENTION & NOTES DURING CONSTRUCTION

Intensify mitigation measures and limit construction activities out of administrative time (break of residents) near residential areas

Noise and exhaust fume dispersion might have affects on nearby cultivation plots; therefore, the Contractor should pay attention to implement inventory and compensation for these damages and affects.

CURRENT SITUATION

The route will runs through the outer corner of residential area and some households (which will be affected by construction but be isolated by the route)

The cultivation area is quite small; some areas of existing ditch will be cut by the route and should be replaced by road-crossing culverts as designed.












Separated ditch



The beginning section of the ditch is separated





CURRENT SITUATION

The route mainly runs through cultivation area. It is far away from residential areas and nearly overlaps the administrative border between Dong Thai and Hong Tai communes.

At the ending section of the route, the route cuts the local road of Xich Tho village.

Some households (which shall not be relocated) will be only 20 cm far away from the road edge.

Te Chu pagoda is located near the route will be likely affected by the noise.



ATTENTION & NOTES DURING OPERATION

Prepare construction plans to coordinate with harvest time of the locality and ensure a temporary flow of irrigation water.

Study the solution for local roads for remaining households or intersection or local roads which are connected with road No.351 or An Kim Hai canal

Establish row of trees for reducing noise and air pollution for residential areas (in Hy Tai village) and following the direction of Kien Phong pagoda.

Control surface water pollution

Check safely for overhead construction, especially electric safety at the section where the 110kV electric line is cut by the route.

Implement traffic control and arrange staff in charge of traffic diversion (coordination of traffic police will be required at this section), in order to ensure the safety during construction.

Priority should be given to establish reasonable storages, especially gasoline storage; workshop for maintaining construction vehicles should be 100m far away from the river.



ATTENTION & NOTES DURING OPERATION

Constantly check the deflection of 110kV electric line where the route runs by and limit arising risks in stormy weather.

Implement planning and changing land using target for the cultivation plot close to dyke footing (with small area) for reducing cost.

Consider space under the bridge. It is advisable to establish flower garden and public vehicle keeping place to prevent land occupation for business and selling purposes.
