Mumbai
7/28/2014 3
• Mumbai developed by British
and nurtured by Local
Mumbaikars.
• Earlier comprised of 7 isle now a
metro city
• Financial capital of the country
• Busiest and 1 of the rapidly
growing city in world.
Navi Mumbai• Navi Mumbai is being developed as a counter
magnet to the main city to achieve the goal of
de-congestion of Mumbai
• CIDCO developed a new town Navi Mumbai of
area 344 sq. km.
• Its Asias largest planned and developed city for
population 2 million and 0.8 million jobs.
• high-tech Jawaharlal Nehru Port (JNPT)
catering to International Container Cargo
traffic at Nhava-Sheva is located on the
southern side of the city.
7/28/2014 4
Need of NMIA project?• Mumbai contributes about 40% of total net domestic product of Maharashtra.
• The share of manufacturing sector employment is expected to decline from 35
% to 27% and share of tertiary sector employment is expected to increase from
64% to 72%.
• City is shifting from traditional manufacturing activities to trading and service
activities.
• There is a need of increasing the capacity of airport as the existing Sahar airport
(domestic) and CSIA (international) are not sufficient.
7/28/2014 5
• Mumbai handles (23%) caters for the highest air
passenger
• Mumbai airport at Santacruz is the busiest airport in the
country and handles approx. 23% of total passengers, 31% of
Cargo traffic and 18% of aircraft movement in the country.
Navi Mumbai site
• Located near Panvel town about 45 kms from the
CBD of Belapur.
• 2 runways are planned. Phase wise development is
adopted to meet the air travel demand.
• The site is also proposed to be accessed from Mumbai
by high-speed water transportation system abutting
airport site.
7/28/2014 6
Location and Geography• Located at Panvel taluka, Raigad Dist.
Maharashtra.
• Present site is majorly CIDCO owned and
remaining is private which will be acquired
for airport development.
• SH54, NH4B, Aamra Marg (Running on the
Boundary of Airport site).
• Panvel creek, Gadhi river, Taloja river and
Ulwe river running along and through the
boundary of the airport.
• Ulwe hill – RL 82 Mts. within the site.
• Elephanta at a distance of 13 Kms. West
• Seismic zone :Zone-III as per IS: 1893 (Part-I)
2002.
• Study area falls in coastal region of Konkan
area.
• Panvel 1.5 kms. on Central Rly./Konkan Rly.
Khandeshwar – 1 km. suburban Rly..
7/28/2014 7
The study area is about 10 kms
in radius around the airport site.
Description Of Environment
• Study area covers the district of Thane and Panvel.
• Climate is hot and humid.
• it is included in Deccan Trap where all the balastic
compositions are surrounded by large no. Of dykes.
• Taloja river and Kasadi river in the North, Kalundri and Gadhi
river in the East and Ulwe river in the South.
• The physico-chemical parameters ranges value within the
prescribed standard except the BOD and nutrients.
• A total of 58 species of birds, 46 animals, 23 aquatic animals
and maximum of 198 plant were found in study area.
• There is no forest area in the project area.
7/28/2014 8
Description Of Environment• 50% of project area is open land, salt marshes cover another 25%,
10% under mangrove forest, rain fed agriculture occupies 7% area
rest is man-made things in the project area.
• Open land:
– hilly terrain extending NW and is towards the SW end of the proposed runway.
• Salt marshes:
– more common in the Eastern region of the site of proposed airport than in the
west.
– Used for Prawn culture and are also man made.
– No life as anaerobic condition prevails.
• Mangroves:
– Avicennia marina more dominant species found here.
• Agricultural Land:
– rain fed agriculture in mansoon else barren land.
– Brick making also observed.

Description Of Environment
• area includes places of
historical importance
such as:
– The Elephanta Caves.
– Karnala Bird
Sanctuary.
– Matheran Eco-
sensitive Zone.
7/28/2014 11
Project Activites
• Project area is about
2054 Ha.
• Airport zone is about
1615 Ha. Consisting of
1200 Ha. For
aeronautical activity and
415 Ha. For non-
aeronautical activity.
• Remaining area is there
for utility services.
7/28/2014 12
Positive Impacts
• Project will facilitate the fast movement of man and materials, thereby
fostering trade and commerce.
• support employment generation, CM outlined that around 1lakh direct jobs
and around 4lakh indirect jobs due to this project.
• Pressure on other airport at Santacruz will be eased.
• offer increased accessibility, which in turn fuels the tourism sector which
causes more money flows into the local economy.
• raising the standard of living of the people in the region. provides a thrust
to the GDP of the local region, having a positively impact on the national
economy.
• it will handle 60 million passengers/year which is much smaller than the
international standard of 100 million passengers/year so there is always
possibilities of expansion.

Impacts due to NMIA Location• Removal of Mangroves & Biodiversity:
– With the project intervention, A total of 161.50 ha of mangroves (though in
degraded form) will be lost due to the project.
• Tree clearance:
– There is no forest in the project site area, though there are naturally growing
trees/plants/vegetation in the area.
– This project will result in loss of all vegetation in the project site.
• Roads and infrastruture:
– two impacts namely the over concretization and
– diversion of agricultural land leading to issues of land use change and food
security.
– Though the surface soil is being stripped off for brick making.
• Water ways connectivity:
– stress on the surrounding marine ecosystem and fishing.
• Rehabilitation:
– Ten settlements approx 15000 people will be affected due to the project.
7/28/2014 14
Impacts due to NMIA Project
Design• Training of Gadhi River:
– The impacts of channelization on the aquatic
community mainly arise due to clearing and
removal of vegetation.
– Siltation affects aquatic vegetation by
increasing the turbidity of water.
– loss and reduction in the number of organisms.
• Diversion of Ulwe River:
7/28/2014 15
Impact Due To Construction
Phase• Employment, Migration and Settlement:
– stress in the area surrounding the project in terms of water requirement,
power, increased ecological footprint, increased requirement for health
and educational facilities and changes in the land use pattern and local
culture.
• Siting of construction camp for construction:
– stress on the local ecological resources
• Leveling of site:
– leveling process would lead to an intense / heavy quantity of dust
which would raises the SPM levels in the vicinity.
– the noise levels would be high due to the machinery used for leveling.
• Safety of Workers
• Construction Activity
7/28/2014 16
Impacts during Operation Phase
of NMIA• Operation of airport:
– two major impacts
include that of air
emissions and noise.
• Surface Traffic:
– air quality is affected
– Noise also is affected
• Employment,
Migration &
Settlement:
7/28/2014 17
MITIGATION MEASURES
7/28/2014 18
Air sector• Appropriate dust suppression measures will
be implemented within the project site.
• Background air quality of all transport
corridors will be maintained by reducing
idling time and control on emissions.
• Aerobridges would be used for passenger
transportation
7/28/2014 19
Biodiversity and Forests• CIDCO has planned to take up approx 350 Ha. of
plantation of mangroves against the 161.50 Ha. Loss.
• The channelization activities are designed to keep flow
characteristics as close to the original natural flow.
• compensatory vegetation and plantation programme will
be undertaken within the airport area
• contamination of estuarine body would occur mostly
during the construction phase due to resuspension of
sediments or dust from construction site, both of which
are temporary.
• There was no wildlife, observed during the field survey.
Disaster management plan
• Natural Disasters:
– earthquake
– flood
– storms/cyclone
– cloud burst/lightning/extreme
weather conditions
– Fire
• Terror Attack, Plane Hijack,
Sabotage
• A highly equiped airport is
developed to counter all the
calamities and disasters.
• Aircraft Accident Related
Disasters:
– aircraft accident at airport
– aircraft accident off airport
– Hazardous material emergency,
hydrocarbon spills (ATF)
followed by vapour dispersion
and pool fire
– fire

Conclusion• The project is necessary and
should be given a nod.
• Development is necessary, but
development along with
environment is acceptable.
• So adopt sustainable
development.
• Human imagination is
touching sky, sky is part of
environment so better
preserve for imagination
hence future.
• Go green.
