Project - Six-Laning of NH-16 from Narasannapeta to
Bhogapuram in the state of Andhra Pradesh under
NHDP Phase V

9. IMPACT OF PROJECT
Impacts of Location
The road stretch has specific impacts from the location except the
clearances from the statutory authorities. The project does not require
any forest area for proposed alignment.
Impacts During Construction
Borrow Areas / Quarries
The proposed project corridor requires raw materials from 17 borrow
areas, 3 metal quarries and 2 sand quarries. Borrow Areas of Large
quantity of earth/ gravel material is required for widening of formation
and embankment, necessitating earth / gravel from borrow pits.
Solid Waste / Surplus Earth
During the construction phase, the quantity of muck generated is
approximately 4,73,424 cum and same shall be used for filling up the
low-lying areas and some part will be useful for construction of service
roads, etc.

10. IMPACT OF PROJECT
Soil Quality
The problems of soil erosion exist in the
stretch due to varying topography,
erratic rainfall and swift velocities of
water in the drains during monsoon.
Top Soil Loss: The loss of fertile topsoil /
humus may occur because of the
extension of carriageway, hence care
and precaution need to be taken to
preserve the layer and reuse the soil as
it contains the humus.
Soil Erosion: It may occur due to the
uneven topography and intensity of
rainfall. A major problem of erosion may
occur due to the removal of age-old
trees along the roadside within ROW.

11. IMPACT DURING OPERATION PHASE
Impact on Land use.
Road development may lead to
establishment of petty shops
and other commercial pursuits
by the local people.
Local statutory bodies will
strictly enforce land use. In
addition, the project proponent
should prevent development of
squatters settlements and
encroachments on the vacant
portions of the RoW of the road.

12. IMPACT DURING OPERATION PHASE
Impact on Air Quality.
During operation phase
significant positive impact on the
ambient air quality is envisaged
due to ease of the traffic and
reduction in travel distance.
The fuel consumptions and
maintenance cost will also come
down due to the project. The
fuel consumptions are also
estimated for the base year
(2018), interim year (2033) and
ultimate year (2046)
Fuel Consumptions Without and With Project Scenarios

13. IMPACT DURING OPERATION PHASE
Impact on Noise Quality
The major source of noise pollution in the project region is due to vehicular movements on the
highway and noise in the junctions. The noise impact due to the transportation activity depends on
the ultimate traffic volume and the type of the vehicles in operation.
Impact on Biological Environment
Flora
The widening & strengthening of the existing
2-lane to 4/6-lane with paved shoulders as
per NHAI guidelines might require felling of
existing trees along the roadside areas.
Fauna
Terrestrial Fauna: During the construction, no
impact on the wildlife is anticipated.
Aquatic Fauna: The proposed project would
require partial filling up of some ponds. Most
of these ponds remain dry during the non-
monsoon months.

14. IMPACT DURING OPERATION PHASE
Impacts on Human Use Values
Flood Characteristics There are 20 minor
bridges existing in the project corridor.
Presently 7 more minor bridges are also
proposed as per the project requirement.
The entire project stretch is proposed to
be designed for above HFL hence, the
flooding in the area can be avoided.
In the proposed improvement scheme,
embankments will be constructed for
forming bypasses and vehicular
underpasses. These may lead to possibility
of flooding of the project area in the event
of unprecedented rains

15. IMPACT DURING OPERATION PHASE
Impacts on Quality of Life
i. Socio-economics, Land Acquisitions and
Re-settlements
Impacts measures associated with social
environment in the project influence area (PIA),
land acquisition and resettlement of project-
affected persons (PAP) have been dealt.
ii. Accident, Health and Safety
Construction activities will cause hindrance to
the existing traffic flow. Thus, short term impact
in terms of accident is anticipated during
construction phase of the widening project.
Construction of bridges/ culverts shall be
carried out prior to construction of new corridor
at the first stage.

19. • Along the extreme edge of road boundary, fall growing and desert trees shall
be planted at a distance of 1 m from the outer ROW of the project stretch.
• The Flowering plants & shrubs of 66799 nos. with a height of about 2m shall
be proposed to be planted.
• The plantation in the median will serve, as a barrier against glaring
headlights of the vehicular traffic plying in the opposite direction. Further,
this will improve the aesthetics of the road. The suggested plantation is
Bougainvillea, Thevita peruviana (Be still tree), Nerium Oleander (Ganneru
dwarf) etc.
