EXECUTIVE SUMMARY
1.0 Introduction
The Environmental Impact Assessment (EIA) Report for the proposed improvements to the
Project Road from Goa-Karnataka Border to Kundapur (from existing Km 93.700 to Km
283.300) has been prepared according to the World Bank Policies as well as the structure of
the EIA Report presented in the EIA Notification, 2009 by Ministry of Environment and
Forests, Government of India. The EIA is based on detailed field reconnaissance surveys,
inventories and available secondary information.
The existing 2-lane National Highway No. 66 (formerly NH-17) starts from Panvel in
Maharashtra and passes through Karnataka on west coast before reaching to Edapally (near
Cochin) in Kerala. The project road starts from Goa - Karnataka border (km 93.700) and
ends at Kundapur (km 283.300).The total length of project road is 189.600 km based on
existing km stones. The project highway alignment is located between Arabian Sea coast
and Western ghats in Karnataka. At few stretches the highway is close to the Arabian Sea
(within 500m). The project road passes towards South from Goa-Karnataka border through
number of congested towns/villages viz Karwar (km 106.700), Karwar port (km 108.800),
Navy’s Sea bird project, Amadalli (km 124.000), Kumata (km 174.400), Haladipura (km
186.600), Honnavara (km 194.500), Kasarakod (km 197.850), Shirali (km 227.450), Bhatkal
(km 232.350), Shirur (km.245.000), Byndur (km.250.000), Maravanthe (km. 266.000), Tallur
(km.279.500)and other villages in Karawar and Udupi districts before reaching Kundapur
(Km 283.300). A location map of project road is enclosed. Design length of project road
after improvement proposals is 187.240 km length as against 189.600 km of original length.
The project road from km 93.700 to km 283.300 is part of NH: 66 (formerly NH-17) and
length is 189.600 km along existing alignment. The alignment of highway passes through
Plain terrain approx. for 100km length, rolling terrain for 46 km length and Mountainous
terrain for 44 km length. The highway traverses through 36 nos. of major congested
villages/towns before reaching Kundapur. Generally the existing road is on 0.5 to 3m
embankment except at approaches to major bridges, where it is upto 10m. The existing 2-
lane highway has number of sharp horizontal curves at number of locations and the gradient
generally not satisfies the requirements of IRC: 73. The existing 2-lane carriageway width is
7.0m and at built-up section it is 10.0m. The condition of the existing pavement varies from
poor to good.
There are 660 nos. of CD structures present in 189.600 km stretch of project road. These
include 13 nos. major bridges, 41 nos. minor bridges and 606 nos. culverts. Out of 13 major
bridges, one major bridge located @ km 196.200 (across Sharavati River) is retrofitted.
Existing major/minor bridges and culverts are of 2-lane width.

Permission from MOEF is required.
Most of the project road stretch passes through plain terrain. Generally the land use along
the project stretch is mixed with agricultural, forest, residential and commercial.
3.0 Baseline Environmental Profile of the Project Area
3.0.1 General
The baseline environmental studies on the project influence area helps to predict the
magnitude of impacts that are likely to be caused due to the proposed improvements of the
project road. It also helps to identify critical environmental attributes required to be
monitored during and after the proposed developments. In addition to the baseline
environmental monitoring, field inspection at all the sensitive locations, collection of
secondary information for all the environmental components and discussions with the
officials, NGO’s and local public were conducted by the Consultants to prepare the baseline
environmental profile of the project area. Baseline environmental monitoring was
conducted in March-May 2012.
3.0.1 Physiography
The project stretch of National Highway 66 (Formerly NH-17) area lies mainly over the
Western Ghat and Karnataka Coastal region which is a narrow coastal strip to the west
abutting the Arabian Sea with beaches, estuaries, mangrove forests and lowland evergreen
and semi evergreen forests. The project section starts from existing chainage Km 93.700 of
NH-66 (formerly NH-17) at the boundary of Goa- Karnataka with an altitude of 44 m above

mean sea level and terminates at Kundapura at chainage Km 283.300 which lies on an
altitude of 8 m above mean sea level. The project stretch extends between longitude 74o8’
East to 74o42’ East and Latitude 14
o 48’ North to 13
o38’ North. The project stretch traverses
through undulating to plain terrain. The topography shows a general slope matching with
the country slopes mainly from east top west side. The project area lies over Karnataka
Coastal Region, which extends between the Western Ghats, edge of the Karnataka Plateau
in the east and the Arabian Sea in the West. The project stretch falls under the
administrative limits of Udupi and Uttara Kannada districts of Karnataka state. The
proposed project road traverses through all types of terrain patterns viz… plain, rolling and
hilly terrains. The maximum stretch of the project road i.e. for about 100.0 Km passes
through plain terrain, 46 km length in rolling terrain and 44 km in mountainous terrain.
3.0.2 Topography
The topography of the project area is mostly characterised by rolling to hilly terrain. The
terrain of the project area is classified by general slope of the country across the highway
alignment the topography shows a general slope towards West/Northwest as well as south
directions. The project stretch passes through plain terrain from Km 93.700 to Km 107.000,
Km 135.450 to km 147.000, km 216.000 to km 238.000, Km 244.800 to Km 271.000 and
from Km 279.200 to Km 287.000 hilly terrain from km 107.000 to km 114.100, 124.850 to
km 130.140 and from Km 200.000 to 210.000. Rolling and hilly terrain from km 130.600 to
km 135.000, Km 148.000 to Km 154.000, Km 160.000 to Km 191.000, Km 211.000 to Km
214.000, Km 239.000 to Km 244.000, Km 271.630 to km 279.000
3.0.3 Geology and Soil
The major portion of the project area is in West coast plains, which lies between the
Western Ghats and the Arabian Sea from Karwar in the north to a width ranging from 30 to
60 km. The underlying geological formation of the project area is of archaic origin and
consists of metamorphic schist and crystalline gneiss with granite and quartzes phyllites and
charnockites out crops. Generally, laterite rock become apparent on hot, open and exposed
localities, whereas on the moist cool slopes, gneissic soil or red loam is more common. The
older metamorphic rocks constitute mainly the Dharwars and these are represented by the
banded, ferruginous quartzites and by the talc and hornblende schist. The soil in the study
area is of Lateritic type characterized by high iron and aluminum content. Rock outcrops can
be observed intermittently all along the project stretch.
The soils of the project area is of mostly of recent and sub-recent origin; and derived from
laterite and trap formations and are mostly medium type with respect to nutrient status.
The soils of the project area are generally, red gravelly clay soils, Coastal alluvial and Coastal
Laterite soils. These soils are deep, well drained to excessively drained, dark brown to
yellowish red and dark reddish brown sandy clay loam to clay loam surface soils and sandy

the State of Karnataka
ES-v NHAI
clay to clay subsurface soils, moderately to severely eroded with surface crusting. Soil is in
general slight acidic rich in nitrogen, deficient in phosphorus with low to medium potassium
content. The soils of are suitable mainly for rice, sugarcane, groundnuts, coconuts etc.
Recent alluvial deposits are found in river and stream valleys and in coastal areas of the
state. The Coastal soils are of two types, namely coastal lateritic soils and coastal alluvial
soils.
The Coastal laterite soils are found on laterite plateau and dissected uplands. These soils
have formed in sub-humid environment under high temperature and high rainfall condition
and have developed on gneisses and warkali sediments. They are moderately deep to deep,
well drained to excessively drained and dark brown to yellowish red, dark reddish brown to
dark red in colour, with clay dominated by kaolinite, associated with iron gravel. They are
strongly acidic or moderately acidic and have low to medium AWC (<50-100mm), medium
to high organic carbon, low or medium CEC and low base saturation. They are high in
available N and low in available P and K. They are subject to surface crusting and have low
fertility status, moderate to severe erosion problems.
The Coastal Marine Alluvial Soils are formed due to deposition of soil materials in the valleys
after transported form the Western Ghats. These soils are deep, imperfectly drained to
poorly drained and pale brown to dark yellowish brown in colour, and have sandy, loamy
sand, loam and clay surface soil and sand to loam sub-soil. They are strongly acidic to
moderately alkaline in reaction and low to medium AWC (<50-100mm); organic carbon
content is low in sandy soils but high in loam and clay soils, the soils have high CEC and high
base saturation, and are low to high in available N, and low in available K. They are
vulnerable to drainage problem and flooding. The sandy texture is a drawback.
3.0.4 Seismology:
The entire stretch of the project road falls under the seismic zone III as defined by the Indian
Standard (IS) 2002 seismic zoning classification system, i.e. a zone of relative stability. The
horizontal seismic coefficient for zone III is 0.04 measured on a scale from II to V where zone
II is most stable and Zone V is considered to be least stable.
3.0.5 Meteorology
Climate
The entire project area belongs to climatic zone of Coastal Karnataka. The project area
experiences Tropical Monsoon climate which covers the entire coastal belt and adjoining
areas. The climate in this region is hot with excessive rainfall during the monsoon season
i.e., June to September. The winter season from January to February is followed by summer
season from March to May. The period from October to December forms the post-monsoon
season. The period from October to March, covering the post-monsoon and winter seasons,
is generally pleasant over the entire State except during a few spells of rain associated with

north-east monsoon which affects the south-eastern parts of the State during October to
December.
The months April and May are hot, very dry and generally uncomfortable. Weather tends to
be oppressive during June due to high humidity and temperature. The next three months
(July, August and September) are somewhat comfortable due to reduced day temperature
although the humidity continue to be very high.
Temperature
Being located on the coast, seasonal temperature variations in the study area are small. The
month of April and May are usually the hottest month of the year. While maximum
temperature remains around 32.70
C and minimum stays at around 290 C. Night
temperatures move down to about 21.4o C .
Rainfall
The project area, receives high amount of rainfall from South-West Monsoon owing to its
coastal location and being situated close to the Westerns Ghats. The average annual rainfall
of the area is 4119 mm in the district of Uttar Kannada whereas in Udupi District average
annual rain fall is 2835 mm against the state average of 1139 mm. The normal rainy days
vary between 105 days to 112 days in the different areas of project locations. Fig 9.4
indicates the monthwise normal rainfall in Uttar Kannada and Udupi district. The analysis of
month wise rainfall data indicates that almost 78 percent of the total annual rainfall is
received during the Southwest monsoon season between June to September in both the
districts. More importantly, the months of June and July alone receives more than 58
percent of total annual rainfall. The period of December to April may be considered as dry
season during which the area receives few spells of rain amounting just 1.6 percent of the
total annual rainfall.
Humidity
The climate of the study area is marked by high humidity and oppressive weather in hot
season. Morning monthly mean relative humidity ranges from 73 percent to as high as 90
percent in Karwar and the evening relative humidity ranges from 63 percent to 86 percent.
Comparatively Honnavar Town shows higher variation of relative humidity which ranges
from 64 percent to 92 percent during morning hours whereas the same varies from 58
percent to 86 percent during evening hours.
Wind Speed and Wind Direction
The winds are strong and mainly western and south- westerly in southwest monsoon
months. For rest of the year, winds are mainly from north and east in the forenoons and
westerly and north –westerly in afternoons. Most of the period the wind speed is moderate
in Honnavar except for few days when area experiences high winds of more than 20 km/h

ES-vii NHAI
during the months of May, June and July whereas in Karwar the high wind speed is more
frequent than Honnavar. The area experiences higher wind speed during afternoon. The
winds in the range of 5.9 kmph to 9.5 kmph are more frequent in Honnavar Whereas the
same varies mostly between 5.3 kmph to 15.6 kmph in Karwar town. In general the project
area experiences predominant SW winds during monsoon season and occasionally it is
under the influence of cyclonic winds. However, the local influence of sea & land breeze
phenomena is also significant at the project area.
3.0.7 Hydrology
The project alignment is passing/abutting several water bodies such as Rivers, Nalas,
Irrigation canals, lakes, ponds, wells, hand pumps, deep tube wells and over head tanks
(OHT). The project road is crossing the Aghanashini River, Sharavathi River and Souparnika
River respectively. Other than these, at 39 locations the project road is passing through
streams/canals (and requires construction of minor bridges). And 141 culverts also exist
along the project road.
3.0.8 Ambient Air Quality
The baseline status of ambient air quality has been established through a scientifically
designed network of Ambient Air Quality Monitoring (AAQM) stations set up at 6 locations
along the project road representing different conditions like rural, urban, residential
commercial and industrial areas. The monitoring was done for 24 hrs for one week. The
results show that all the ambient air quality parameters are well within the revised NAAQ
Standards at all the locations. There are no major air polluting sources in the project area
and generally the air quality of the area is found to be good.
3.0.9 Surface and Ground Water Quality
Water samples were collected from eight locations along the project road. Out of these
surface water samples drawn from 4 locations and ground water sample drawn from 4
locations. The analysis reports were compared with the relevant standards; IS: 10500 for
ground water and IS: 2296 for surface water samples. It was found that all important
parameters were falling within the prescribed limit.
3.0.10 Noise Levels
Out of the 6 locations where noise level has been monitored, three represent residential
areas and one each location represents silence, commercial and industrial area. Day time
noise level in all the locations exceeds the prescribed limits of CPCB standards. In all
locations noise level exceeds the prescribed limit for night time.

ES-viii NHAI
3.0.9 Flora and Fauna
Flora: Inventory of trees along the project road was carried out. Approx. 23491 trees of
different girth and species are present within the impact corridor of 60m from centre line of
existing highway. Cashew nut farms are present close to the vicinity of the project road.
Acacia arabica (Babul) is the most widely distributed tree along the project road, followed
by Tectona grandis (Teak), Azadirachta indica (Neem), Eucalyptus globulus (Eucalyptus),
Ficus religiosa (Peepal tree), and Dalbergia sissoo (Indian Rose wood tree) at the top
positions in the order of spatial distribution along the project road.
Fauna: Cattle, buffaloes, sheep and goats are the common livestock found in these districts
apart from poultry birds.
3.0.10 Eco-sensitive issues
Base line data collected after field reconnaissance critical issues are identified for further
study during environmental impact assessment and to evaluate mitigation measures. The
likely environmental impact to the environment include soil erosion, Forests, road side
vegetation, sea and CRZ, water resources, Defence area (sea bird – Navy project), port,
religious centers, Mangrove forest etc.
Forests and Protected Areas
The project road passes through Reserved and Protected Forests at several locations. The
forest maps of the project road were collected from I.T. Department, Karnataka State Forest
Department to identify the affected forest land due to proposed project improvements.
During design stage, at many locations diversion of forest land is avoided to minimise the
impact on forests biota. Further, at some locations where forests present on both sides, the
design RoW is restricted to 30 m. Total forest land to be diverted for the proposed project is
estimated to 146.0Ha. Teak trees are predominately planted in the Reserve forest areas.
Animals such as Cheetah, Sambar, Nilgai, Wild dogs, Gaur, Sloth beer, jackals, fruit eating
bats, mongoose and hare; reptiles such as rat snakes, cobra and turtles; and birds like
peacocks, mynah, bulbul, kites and pigeon were also found in the forest areas of these
districts.
No Protected area such as National park or Wildlife sanctuary was observed within 10 km
distance from the project road.
Mangrove forests
Mangrove forests are present at 13 locations along the existing ROW. The river with
mangrove is declared as CRZ-1.

the State of Karnataka
ES-ix NHAI
Patches of reserved Forest area are present on the project road. This needs further study in
coordinate with Forest department and Revenue department.
There are 13 major bridges constructed across rivers/streams flowing towards west the
water bodies supporting mangroves are considered critical as these are of ecological
importance. These water bodies located likely to be affected during construction and may
suffer from risk of contamination and therefore such sections are ranked as high sensitive
zones.
Coastal Zone
The existing highway section falls under CRZ-1, CRZ-II and CRZ-III. The rivers which support
mangroves come under CRZ-1. Karwar section of highway from Km. 103.00 to Km. 110.00
falls under CRZ-II.
3.0.11 Social issues
Settlements
There are number of settlements (60 nos.) on the project road. The congested locations
include Karwar, Amadalli, Kumta, Haladipura, Honnavar, Shirali, Bhatkal and Kundapur.
Large scale acquisition of land/buildings is required at these locations which imply
Resettlement and Rehabilitation of affected families.
Religious Structures
Numbers of religious centres are located close to the highway. These structures are likely to
be affected during widening. Hot spots will have to be given due importance before
finalization of alignment to reduce affect of sentimental feelings of local residents.
Accident zones
There are number of accident zones/stretches where sharp horizontal curves are present.
These are required to be realigned / redesigned to minimize number of accident spots.
3.0.11 Land use
Land use along the road is of mixed nature with industrial, agricultural, forest and barren
land. Land use along the highway is predominantly built up and agriculture. Majority of the
land is being used for wet crops viz. Paddy. There are number of settlements all along the
road. The settlements are for Residential, Commercial, Schools, Hospitals, Petrol stations
etc. Forest patches are situated along the existing ROW at many locations. Naval base is
also a significant feature along the existing highways at Karwar. The highway encounters a
number of water bodies and it comes closer to Arabian Sea at few locations.

4.0. Assessment of Potential Environmental Impacts
4.0.1 Potential Negative Impacts of the Project during Construction Phase
The activities during the construction phase of the project road includes leveling of site,
clearing of trees along the alignment, widening of existing road with paved shoulders,
construction of culverts and bridges, and quarry operations for the road work. Some of the
potential direct and indirect negative impacts of the project during construction phase will
be the following.
• Filling in low-laying areas for embankments of the road
• Diversion of forest areas and cutting of large number of trees
• Loss of topsoil due to clearing and grubbing of vegetation for new alignment, borrow
area and quarry operation, construction camps and material stacking yard
• Temporary impacts on flora and fauna due to the construction activities
• Temporary impact on the drainage pattern due to embankment, culvert and bridge
constructions
• Impact on traffic management system
• Increased air pollution (including dust) during project road construction
• Increased noise levels due to the movement of vehicles and construction activities
• Increased soil erosion leading to loss of top soil and pollution of surface water bodies
• Spillage of oils and other hazardous materials leading to pollution of surface and sub-
surface waters
• Pollution of rivers and canals due to construction of bridges and culverts
4.0.2 Potential Positive Impacts of the Project
The positive impacts of the project are
• Reduction in air pollution along existing road due to reduction in traffic congestion
and smooth vehicular movement
• Reduction in air and noise pollution and accidents in built up areas due to
construction of bypasses.
• Reduction in fuel consumption and travel time due to better service level of roads
• Improved safe and efficient connectivity between Uttara Kannada and Udupi
Districts.
• Generation of local employment during road construction
• Improvement of local economy and industry due to better infrastructure facilities

ES-xi NHAI
4.0.3 Potential Negative Impacts of the Project during Operation Phase
During the operational phase of the project, traffic in the project road and the average
speed of vehicles will increase. Some of the potential direct and indirect negative impacts of
the project during operation phase are the following.
• Increased noise pollution along existing road due to the vehicular movement at high
speed
• Increased air pollution along existing road due to newly introduced vehicular traffic
• Impact on natural drainage pattern of the project area
• Pollution of water bodies and impacts on its ecosystem due to hazardous chemical or
oil spillage into the canals and streams
5.0 Analysis of Alternatives
To avoid traffic through congested areas and the subsequent impacts as well as to reduce
resettlement issues, realignment options were considered. Twin tunnel was recommended
to Karwar Town and widening of the existing road was recommended to other towns viz… i)
Kumata Town, ii) from Kumta Town to Honnavar Town, iii) Haldipura Town, iv) Karki Town,
v) Honnavar Town and Kasargod Village, vi) Bhatkal Town and vii) Maravante Village.
Several alternative options have been assessed after collecting and analysing the field data.
These options have been considered based on the impacts of project improvements on the
built up areas as well as natural environment, land acquisition and overall high way design
standards stipulated for National Highways.
The widening option was finalized based on techno-feasibility as well as environmental and
social impacts. Summary of list of recommended options are presented in Table 3.0.
