CONSTRUCTION PHASE (a) Natural EnvironmentSoil and MaterialTopsoil Loss of fertility of arable

land The topsoil (about 15cm) will be kept and refilled after excavation is over to minimize the impact on productive lands.It may be necessary to construct new access roads to aggregate sites, and place them through agricultural lands. These temporary roads will be made along existing farm tracks so as to avoid losses to agricultural lands. Contractors will be required to present proposed construction road alignment and hauling schedule for approval before construction is to commence. In unavoidable circumstances,

suitable compensation will be paid to people whose land will be temporarily acquired for the duration of the operations. The compensation will cover for loss of income for the duration of acquisition and land restoration.

Contractor DPWH,CSC The contractor’s excavation activities only concentrated on the construction limits per approved plans, complied the EMP.

Soil erosion -High suspended soil contents of river, sedimentation

Visual monitoring and inspection of soil erosion at borrow areas, quarries embankments and other places expected to be affected, will be carried out once a month for dry season and once a week for rainy season as suggested in monitoring plan. On hill sections and other erodible site,

Contractor DPWH,CSC The construction supervision team considered the highly prone landslide areas by putting up berm and catchwall.

appropriate vegetation that retards erosion will be planted. Design consideration for erosion: slope and pier protection with retaining structure. Construction activities in hilly areas to be taken up only during dry season.

Reclaimed pavement Solid waste Contractors will be encouraged to recycle reclaimed aggregate in granular or stabilized surface material for subgrade and base layers and village access road maintenance and to use recyclable materials as much as possible. The material that cannot be reused will be taken to specific official waste dumping sites approved by the DENR. All suitable material obtained from roadway excavation work will be used for construction of embankment/earthen shoulder

Contractor, LGU Residents

DPWH, MMT, CSC

Not applicable. All existing PCCP are exempted from the project.

Slope Stability Landslides

-During cuts and excavation works, instability of soil or potential failure of exposed soil and rock materials can take place.

Retaining structures will be constructed for protection of landslides for the Project. The long term solution for landslides will be to maintain uphill vegetation cover, and appropriate agricultural activities in the steep banks with a diversification of crops and cropping techniques.

Removal of vegetation and cutting of trees will be done judiciously and limited to minimum possible extent.

Vegetative cover by planting grass and coconut are considered for the identified eroded section.

Contractor DPWH, CSC The constructions of catch wall and landslide protection were already considered in our preparation of As-stake plans.

Degradation of borrow areas

Loss of topsoil and disfigurement of landscape

Borrow pits and quarries will be redeveloped as per standard procedure. Rehabilitation of quarries and borrow sites will be undertaken immediately after excavation to prevent soil erosion.o Redevelopment will include:o Regrading slopes to minimize erosion,o Replacing stockpiled soil cover,o Replanting grass, shrubs, and trees,

Contractor DPWH, MMT, CSC

Cutting and removal of vegetation only up to the design construction limits

Quarry sites located close to the alignment with high level of accessibility and level gradient are preferred

Operation of quarry site on river banks

Sedimentation and siltation downstream and riverbank destruction

Changing the river pattern will have a beneficial impact to the flow regime of the rivers

No work will be permitted to site with fine sediments.

The depth of excavation from the river will be limited

Identify the riverbed, which has excessive sediments, and limits the excavation to ideal section and depth of the river

Permit to quarry site away from drinking water intakes and tributaries used by the community for domestic purposes

Depth and area of extraction limitation should be imposed to prevent loose materials disturbance that may trigger siltation. However, since one of the major problems in the area is soil erosion, landslide and flooding, excavation should be done in such a way that the flow of rivers should be improved.

Contractor LGU, DPWH, MMT

Siltation Adverse effects on channel stability Increasing coverage of open surface area

by planting grass so that washing away of materials from sloped surfaces would be reduced to a significant extent.

Construction materials containing fine particles, e.g. limestone or laterite, should be stored in an enclosure such that sediment laden water does not drain into nearby watercourses, but rather
