- Construction activities and
increase of vehicle volume
after the opening of expressway
increase the level of noise and
vibration
- No protected area was
confirmed within the project
area. Thus, no negative
impact is expected
- Four animals are designated
as endangered animals and 15
animals and three plants are
designated as vulnerable
species 4 . According to the
interview with commune
heads, about two to three kinds
of endangered animals, about 5
to 7 vulnerable animals and
two vulnerable plants were
witnessed by residents in the
Project area. Detailed survey
to identify the habitat of these
species should be carried out in
the further <strong>study</strong>.
- Aquatic ecosystems in the
river will be disturbed during
construction phase
-The piers of bridges are not
constructed in the river. The
disturbance resulting from the
construction activities,
however, affects some negative
impact on water flow.
- The project entitled “My
Thuan Bridge Up-Stream Bank
Protection” has been under way
by the MOT at the upstream
area of the proposed bridge
construction site in order to
protect riverbank. Thus,
riverbank runoff is not
expected.
- Slope failures or landslide
along the proposed project’s
route are not expected.
-Soil runoff resulting from
cutting and filling works occurs
during construction phase.
4-9
- Avoid construction works at nighttime (10 PM-6 AM)
- Locate vibration generation sources at more than 50 m away
from residential sites
- Locate concrete mixers and asphalt stations at least 300 m away
from residential areas
- Inform local residents on time/schedule and plan of
construction activities in advance
- Install noise control walls at sources of loud noises to minimize
impact near sensitive institutions (temples, schools, etc.)
- Undertake regular maintenance of vehicles and construction
machines
- Install noise control walls at sensitive institutions (schools,
temples, etc.)
- Implement noise monitoring
- Conduct detailed survey for the habitat of endangered and
vulnerable species and prepare appropriate mitigation measures
- Limit water turbidity during digging and dredging to minimize
disturbance to aquatic ecosystems in the river
- Control the disturbance to the hydrology of the river during
construction phase
-
- It is recommended to monitor the riverbank runoff periodically
during the operation phase.
- Gather waste soil and stone on separate dumps
- Recover vegetation level at excavated vegetation area
-Minimize excavation works and embank surface area during
rainy season
4 These species are listed in the Red Data Book of Animals, 2007 and the Red Data Book of Plants, 2007 issued by Vietnam
Academy of Science and Technology.
