Strategic Cities Development Project

Environmental Screening Report

1. Project Identification

Project title Improvements to Puloly - Kodikamam road section of Puloly –

Kodikamam, Kachchai Road ( AB31), Strategic Cities Development

Project

Project Proponent Ministry of Megapolis and Western Development

2. Project Location

Location

(relative to the nearest town,

highway)

AB 31 road is located in Jaffna District and it starts from Kodikamum

Junction of the A9 road and travels through 3 Divisional Secretariat

Divisions namely Chavakachcheri, Karaveddy and Point Pedro providing

services to 13 GramaNiladhari Divisions, up to the Manthikai Junction of

Jaffna Point Pedro Road.

Definition of Project Area

(The geographical extent of the

project & areas affected

during construction)

Starting from Kodikamum Junction of the Kandy – Jaffna Road (A9 Road)

up to Manthaikai Junction along Jaffna Point Pedro Road (14.2 km) (Ch.

0+000 ~ 14+220 km) is proposed for rehabilitation under SCDP Jaffna city

region interventions.

The areas affected due to proposed road rehabilitation will be mainly

confined to the existing road corridor including the carriageway,

shoulders/ walkways/ embankments and the road reservation, thus some

minor acquisitions beyond the existing road reservation may be

needed.(Location Map is Annex as 1)

Adjacent land and features

Land use features of this road segment can be categorized into following

four distinct characteristics;

Residential-type home gardens.

Wetland and agricultural lands (Paddy, Onion, tobacco etc.)

Concentration of commercial establishments at major junctions and

small townships (Kodikamum Junction, Manthai)

3. Project Justification

Need for the project

(What problem is the project

going to solve)

Kodikamum is one of the small townships located along theA9 road at

Chawakachcheri Divisional Secretariat and the AB 31 is the road

connecting Kodikamum and Point Pedro.

The road identified for rehabilitation is a link road connecting the

Manthaikai Junction where the wholesale market place is located. Since

the predominant economic activity of this area is agriculture and the

provision of infrastructure facilities for transportation of local agricultural

products to the market place is important. Investment on the road



rehabilitation has a direct impact to the local economic development.

Point Pedro is the north most point and one of the tourists attractivearea of

the island. Thisroad link is strategically important to reach Point Pedro

without entering Jaffna city andavoid traffic during peak hours.

The areas affected during construction phase due to proposed road

improvements and other project activities will be confined to the

improvements of existing road into two lane of 3.2 m wide and 0.6m hard

shoulder and 0.6 m soft shoulder. (All together 4.4m from centre

line).Additionally the physical development is limited to construction of

walkways/ embankments, culverts and shifting of other utilities(electricity

& Telecommunication poles and water supply lines etc.) as specified in the

plan.

Purpose of the project

(what is going to be achieved

by carrying out the project)

Even though the traffic congestionis relatively a lesser problem in Jaffna

compared to the other cities in Sri Lanka and effective capacity of most of

the road links in Jaffna peninsula are significantly lower than ideal

situationsto match with the future demands. Such poor conditions are due

to the inadequate shoulder/walkway widths, narrow lane widths of most of

these link roads. Thus it is observable that most of the roads in the Jaffna

peninsula have to be re-visited to accommodate the requirement of

different road users and with proper intersection control, channelization

etc. to provide a catalyst for accelerating development currently

constrained due to a long period of conflict. It also has potential for

directing development to the most efficient locations and thus developing

efficient linkages for both passenger and goods movement both within the

region as well as outside to make it more sustainable.

The Kodikamam to Point Pedro section of Puloly – Kodikamam –

Kachchai (Point Pedro) road is AB class roadwhich is heavily used by

traffic travelling to north most parts of the Jaffna peninsula. The surface of

this road is relatively poor in condition at present. Structural and surface

improvement of the AB31 road is having a remarkable potential would

lead to improved speed and would reduce journey times by at least 10

minutes per journey, while also reducing vehicle wear-and-tear and

making passenger journeys more comfortable. Additionally smooth flow

of traffic, especially heavy vehicles and improve access from Point Pedro

and surrounding areas to the A9, thereby improving accessibility and

lowering costs for fishery and other products. It also improving access to

the bus stand and railway station at Kodikamam. The road improvement

would have little impact on dwellings or other activities, and is deemed to

have high potential for quick development.

The road passes through wetlands and paddy fields where embankment

protection is needed to avoid damages due to embankment failure.

Shoulders and walkways need to be constructed along almost the entire

stretch. Roadside storm water drains are to be provided where necessary to

facilitate fast drainage.

Alternatives considered

(different ways to meet the

project need and achieve the project purpose)

No other alternative is considered for this particular project since this road

section is the only link road available for rehabilitation connecting the two

small townships.



4. Project Description

Proposed start date April 2017

Proposed completion date April2018

Estimated total cost 1250 Mn SLR

Present land ownership Road Development Authority (RDA)

Description of the project

This road is proposed to be developed as the main access route to Point Pedro, and once developed the

vehicles can move from Kodikamumum without passing through Jaffna. This road is owned by Road

Development Authority (RDA). The total length of AB 31 from Puloli (Manthai) Kodikamum (Ch. 0+000

to 14+220) is 14.2 km. This road section is to be developed to a 2 traffic lane of 3.2 m wide and 0.6mhard

shoulder and 0.6 m soft shoulder. The pavement structure will be strengthened to suit the loads and traffic

forecasted.Horizontal alignment & vertical profile have been selected in such a way that they satisfy design

criteria,hydraulic requirement and minimize land acquisition.

Traffic Forecast

History Traffic Data was obtained from Planning Division, Road Development Authority and the current

traffic data was obtained through traffic counts.

Pavement Design

Asphalt Concrete surface with Dense Graded Aggregate Base will beused based on the subgrade CBR

(California Bearing Ratio) value and Traffic class. The pavement thickness was designed to the traffic



forecasted for 15 years. To make economical pavement design total pavement layers are applied in two

stages. The first layer of 60mm asphalt concrete will be applied at the initial construction

Materials and Method of Construction

Material and method of construction has to be selected according to the references given as follows.

Drainage

The design of the road has been done with the provision of adequate drainage of the road surface by shaping

the carriageway with a camber or a cross-slope to avoid surface ponding and subsequent damage to

grade/sub-base and embankment while ensuring safe motorable conditions without the risk of aquaplaning/

hydroplaning at standard vehicular speeds. Improvements to the existing drainage facilities are required to

establish an efficient system of drainage throughout this road stretch by way of, side drains and cross drains,

catch drains in embankment slopes, cross drainage structures (culverts and bridges), lead-away drains, etc.,

to collect storm water runoff and safely discharge them to the nearest natural water course with no or

minimal impact to the existing environment.

Project

Management

5. Description of the existing environment

5.1 Physical features – Ecosystem components

Topography and

terrain

The Jaffna Peninsula is situated in the North most coastal plains of the island

where most of the land is flat and geographically laid between longitude 790 54’

to 800 2’ E and Latitude 90 30’ to 90 50’ N with an area of approximately 1,129.9

km2of which lagoonsoccupy 45.7 km2.The topography of the area is low and flat

and the lowest ground level of the project area is around 0.8m Above Mean Sea

Level (AMSL) andhighest ground level is about 8m. The project area lies in the

lowest peneplain, which is a gently undulating torolling, mantled plain stretching

down to the coast. The highest ground level is 11 m above meansea level

(AMSL). The land forms include floodplains, coastal plains, sand dunes and

beaches.The Jaffna Peninsula consists of coastal plain type II and limestone

plateau physiographic regions.

(Physiographic regions annexed as 2).

Soil (type and

quality)

The soil and water resource of the Jaffna Peninsula are both related to the lime

stone geology of the land. The soils are formed on the marine deposits and

sediments under the influence of sea waves and winds on lime stones.Tile lime

stone being a porous rock is the source of groundwater for the Peninsula.Well

drained and high productive calcic Red Yellow latasol andRed Yellow latasol

soil types are found in central areas (60,000Ha). Alkaline saline soil and

Regasol are found in coastal areas (26000Ha) and Alluvial soil is inValukaiAru

area (10000Ha). In certain areas coral lime stone is available. This different soil

types offer scope for cultivation of exotic as well as local crops.Tile depth of soil

varies from 90cm- 150cm. (Geology and Soil map annexed as 3)

Surface water

(sources, distance

from the site, local

uses and quality)

In Jaffna, traditionally, surface water has been regarded as “dirty” and

groundwater as “purified”, and surface water is collected and conserved only as a

means of infiltrating as much water as possible into the ground. Surface water in

ponds is not considered acceptable to the Jaffna population as a source of

drinking water because it is used for bathing and washing clothes, watering

livestock, etc., and is frequently polluted from catchment areas. Dug wells in

close proximity to the ponds are however accepted as sources for drinking water.

Ponds hold in storage part of the water that would have escaped to the sea.

The Jaffna Lagoon is a semi enclosed waterbody connected to the Palk Bay. It is

45,000 ha in area. It is surrounded by a dry zone land mass and due to being

greatly influenced by freshwater input, has different physical conditions to that

of the larger Palk Bay. The lagoon contains a number of coastal wetland habitats

and is an important breeding area for numerous marine species. Jaffna Lagoon

has been identified as an IBA by Birdlife International.

The lagoon is relatively shallow with the maximum depth being less than 3m.

The shoreline is composed mostly of sandy soil while the bottom is mostly mud.

The salinity in the lagoon is greatly influenced by rainfall and freshwater run-off

from surrounding areas, and varies from a low around 10.3 ppt during the rainy

season to a high of around 45.49 ppt during the dry season. The lagoon is located

in the dry semi-arid zone with an average temperature of around 270C and an

annual rainfall between 500-700 m. Thesetake the outflow from roadside drains

in to the ponds but not in good condition. The water flowing in these canals are

polluted with wastewater, solid and liquid waste coming in from the small city

centres and residential areas along the road trace. (Map of wetlands of Jaffna

peninsula annexed as 4)



Groundwater

(sources, distance

from the site, local uses and quality)

Jaffna peninsula has a source of Ground Water store in the subterrain layer of

limestone.The limestone is the main aquifer. This aquifer has several isolated

caves and caveins capable of storing ground water without evaporation losses. It

is anexcellent aquifer. The entire ground water is generated from percolated

rainfall and it forms a freshwater lens beneath the peninsula. It is found that the

fresh water lens do not extend below the base of the lime stone. The fresh water

lens is sustained by the buoyancy of fresh water in relation to sea water.

Difference in density, (1.0, 1.025) giving a ratio of 40:1. That is every meter of

fresh water above the sea level requires a depth of fresh water lens of 40m when

no mixing between fresh and seawater takes place.There is no sharp interface

between fresh and seawater (Sketch of Geology and condition of groundwater in

the Jaffna Peninsula annexed as 5).

Flooding Low line areas of Jaffna peninsula is most vulnerable for flooding and most

likely to occur in the months ofMay in the first cycle and in December in

thesecond cycle. Jaffna is one of the most frequent districts for flood with respect

to spatial distribution of floods in the country (Flood distribution Map annexed

as 6). Along the selected road stretch several locations experienced frequent

flood specially in Ch. 13+380, 13+520 and 6+960

Landslide Prone

Areas

There are no landslides prone areas in this area ofconcerned.

Air quality

(any pollution

issues)

Air quality monitoring carried out at previous development project sites have

shown that the one hour average for all the parameters is well below the National

Ambient Air quality Standards. These parameters included Particulate Matter of

less than 10 µm in diameter (PM10) Particulate Matter of less than 2.5 µm in

diameter PM2.5 Carbon Monoxide (CO), Sulphur Dioxide (SO2), Nitrogen

Dioxide (NO2) and Ozone (O3) and their concentrations were very low. The

major contributor to pollutants of CO, SO2 and NO2 are the mobile sources.

Considering the project area, where no highly polluting industries exist and the

number of vehicles is much less than in other areas, except in Jaffna town, the

ambient air quality is expected to be within the National Ambient Air Quality

Standards. Moreover, with most of the project area being coastal, the potential to

attenuate any air pollutants is very high due to wind movement between the land

and the sea. Annexure 7 describe the air quality levels within JMC area. This

includes measured baseline ambient air quality levels. The measured baseline

ambient air quality levels at the selected locations were well below the Ambient

Air Quality Standards as stipulated by the Ministry of Environment and Natural

Resources of Sri Lanka (Extraordinary Gazette, No. 1562/22, August 15, 2008).

Noise level and

vibration

(Any anticipated

issues)

This is a common phenomenon in most of the cities and along the roads, and

Jaffna is no exception. The blaring of horns and noise from loudspeakers in

music centres is quite disturbing. In general, the air and noise pollution problem

is aggravated due to the narrow thoroughfares, in the small townships along the

road.

5.2 Ecological features – Eco-system components

Vegetation

(trees, ground cover,

aquatic vegetation)

The main land use types found along the road trace are commercial

establishments, public building such as schools, offices, religious places etc.,

scrublands, home gardens, abandoned lands, marshy lands including freshwater

marshes salt marshy lands, mud flats, water holes, ponds, canalsabandoned and



cultivated seasonal / perennial crop lands.

Most of the scrublands observed in the project area are essentially in a state of

accelerated flux that develops in places where land has been abandoned after

human use or due to excessive degradation of forest. Scrublands/ Grassland

habitat types are characterized by having a single stratum of shrubs (2-4 m in

height) forming dense thickets. The dominant species recorded in this habitat

includes Cynodondactylon, Cressacretica, Blumeaobliqua, Cyperusstoloniferus,

Phyla nodiflora (Hiramanadetta), Carissa spinarum (HeenKaramba), Phoenix

pusilla (Indi), Vernoniazeylanica (Pupula), Maytenusemarginata,

Diospyrosferrea, Euphorbia antiquorum (Daluk), Flueggealeucopyrus

(Katupila), Jatropha gossypiifolia, Cassia auriculata (Ranawara),

Dichrostachyscinerea (Andara), Cassythafiliformis, Azadirachtaindica

(Kohomba), Syzygiumcumini (Madan), Scutiamyrtina, Ziziphusmauritiana

(Dembara), Ziziphusoenoplia (HeenEraminiya), Canthiumcoromandelicum

(Kara), Catunaregamspinosa (Kukurumanna), Ixorapavetta (MahaRatambala),

Morindacoreia (Ahu), Toddaliaasiatica (Kudumiris), Azimatetracantha,

Gmelinaasiatica (Demata), Lantana camara (Gandapana) and

Cissusquadrangularis(Heressa).

Water holes, ponds, freshwater marshes and canals are the habitats that are

mainly dependent on rain water. As they have a lower capacity these water

bodies become completely or partially dry during the dryer season that prevails

in the area from April to September. As these are fairly shallow water bodies,

rooted aquatic vegetation such as Nymphaea pubescens(Olu),

Nelumbonucifera(Nelum), Nymphoideshydrophylla(Kumudu), Bacopamonnieri,

Fimbristylisspp., Cyperusspp., Hygrophilaschulli(Niramulliya),

Panicumrepens(Etora), Clerodendruminerme(Burenda),

Typhaangustifolia(Hambupan), Tamarixindica(Kiri) and

Premnaobtusifolia(Maha Midi) establish easily in and along the banks of these

water bodies. As these water bodies dry up, the exposed areas become covered

with grass. These seasonal water bodies functions as important biological

repositories.

In lagoon areas and ponds during the dry periods exposed mudflats can be seen.

These are colonized by salt loving herb species such as Cynodondactylon,

Cressacretica, Blumeaobliqua, Atriplexrepens, Fimbristylisspp.

AndCyperusstoloniferus.

Homegarden habitat type in Jaffna is agroforestry based land-use systems where

multipurpose trees and shrubs are found in close association with perennial or

annual agricultural plants near human dwellings. Home gardens are

characterized by multi-storied structureswith mixed but compatible species. such

as Cocos nucifera (Pol), Borassusflabellifer(Tal), Areca catechu(Puwak),

Mangiferaindica(Amba), Phyllanthusemblica (Nelli), Gliricidiasepium(Weta

Mara), Tamarindusindica (Siyambala), Thespesiapopulnea (Suriya),

Azadirachtaindica (Kohomba), Moringaoleifer (Murunga), Musa x paradisiaca

(Kesel) and Commiphoraberryi.

Seasonal crop cultivated land use type is observed commonly in urbanized

stretches where a variety of seasonal crop plants such as Nicotianatabacum

(Tobacco), Musa x paradisiaca (Kesel), Vitisvinifera(Midi), Carica papaya (Gas

Labu), Manihotesculentaenta (Manioc) Zea mays (BadaIringu) and vegetables

like vegetables like vegetables like vegetables like vegetables like vegetables like

Abelmoschusesculentus (Bandakka), Vignaunguiculata (Me Karal),

Momordicacharantia (Karawila), Cucurbita maxima (Wattakka), Beta vulgaris



(BeetRoot), Capsicum annuum (Miris), Lycopersicones culentum

(Takkali),Allium cepa (Lunu) and Allium ampeloprasum (Leeks) are grown. In

many places cultivated lands contain a mixed vegetation except in paddy fields

where Oryza sativa (Paddy) is grown as a monoculture. Perineal crop cultivated

land is another common land use type observed alone the trace. Such perineal

plantations are comprised of either Borassus flabellifer (Palmyra) or Cocos

Cocos nucifera (Coconut) or a mixture of the two.

Presence of wetlands The main wetland habitats that could be found along the road stretch where the

Thondaimanaaru and UppuAaru Salt water lagoons (Ch 2+800 to 5+ 600 ) and

mostly cultivated and abandoned paddy lands (Ch. 0+100 to 2+ 500)

Fish and fish

habitats

Fish and fish habitats are present in the lagoon and the ponds which at certain

locations flow close to the road. However, fish sampling was not deemed

necessary and hence not carried out during the rapid environmental screening

study.

Birds(waterfowl,

migratory birds,

others)

This area is also the primary habitat for a variety of avifaunal speciesincluding

indigenous, endemic and migrant categories due to presence of wetland.

Butterflies According to the butterfly fauna observed along the trace envisage that a rich

butterfly assemblage as nearly 20% of the butterflyfauna of Sri Lanka was

recorded in the region including three out of five species that are restricted to the

northern region of Sri Lanka. Most common species encountered in the field

observations were Castaliusrosimon (Common Pierrot), Chiladeslajus (Lime

Blue), Leptotesplinius (Zebra Blue), Prosotasnora (Common line blue), and

Rathindaamor(Monkey-puzzle)

Other features

Residential/Sensitive

Areas

(Eg, Hospitals,

Schools)

Some of the places along the road stretch can be categorized as most sensitive

due to presence of School (Ch. 0+200 and Ch. 10+360) and Hindu Temples(Ch.

10+700 Ch. 12+740) and residential units.

Traditional

economic and

cultural activities

Traditional home gardens have been observed in many locations along the road

trace. Most of the traditional paddy fields have been cultivated. Some of the

Palmyra trees which used for toddy tapping along the road stretch were

observed.

Archaeological

resources

(recorded or

potential to exist)

No any recorded Archaeological sites alongthe road stretch.

This improvement is currently required by the

people and willing to give their land if it is needed

for the road widening.

The proposed improvements were required by the

people from long time and thus willing to give

required land for the project.

Improvements of this road is necessary and it will

also increase the business opportunities and even

though a tenant of the property willing to replace

Good intervention for development of the area if

it does not interfere with their day to day

economic activities.

This area is developing fast and most of the

agricultural lands are getting productive and

proposed improvement smoothen the access to

urban centres and the project is welcome.

Willing to have this development but does not

agreed to removal of parapet wall due to limited

space for the school building and suggested to

deviate the line to the other side.



7. Environmental Effects and Mitigation Measures

7a. Screening for Potential Environmental Impacts

Screening question Yes No Significance of the effect (Low, moderate, high)

1 Will construction and operation of the

Project involve actions which will cause

physical changes in the locality

(topography, land use, changes in water

bodies,etc?)

Yes Low

Most of the interventions are carried out along the road trace limited to width of 4.4m from

the centre line. Hence no major alterations in terms of physical changes to topography, land

use, and water bodieswould occur due to this project.

2 Will the Project involve use, storage,

transport, handling or production of

substances or materials which could be

harmful to human health or the

environment or raise concerns about

actual or perceived risks to human

health?

Yes Low

Transport of material and construction activities will emit dust, and fugitive particles.

However, the affected area is small and mitigation is straight forward; therefore significance

of the effect can be considered as low.

Dust and other particulate matter will be deposited on roofs, windows, open areas of

households, plants and treesand may be unpleasant and/or create health hazards to vulnerable

persons in the neighbourhood. However, this effect would be limited to a short time period.

3 Will the Project produce solid wastes

during construction or operation? Yes Low

During Construction:

The project interventions, which mainly involvere-surfacing, will not produce significant

amounts of construction debris or solid waste. There will be small quantities of spoilage

(construction debris) produced during demolition of existing structures (mainly temporary)

and excavation of trenches, cut and fill activities, debris from the rock blasting (if any) and

material storage.

During operations:

Good solid waste collection practices will lead to alleviation of any solid waste-related

problems. There will be street sweepings, solid waste collected at garbage bins/ bays and

dump areas which need regular collection and disposal. In addition, debris and sediments,

floating matter and other solid waste carried by surface drainage which can be collected at



manholes, catch pits etc. needs proper disposal. Regular cleaning of side drains and the road

side will also generate such material. Culverts will also generate spoil material.

4 Will the Project release pollutants or any

hazardous, toxic or noxious substances to

air?

Yes Low

There will be bituminous material used during overlay and re-surfacing of roads, bituminous

laying of carriage way and shoulders. Paints and solvents used for road markings can emit

toxic and noxious air-borne substances.

5 Will the Project cause noise and

vibration or release of light, heat energy

or electromagnetic radiation?

Yes Moderate

The project activities will cause noise and vibration during proposed

enhancement/improvement interventions and during transportation of material etc. but, it is

highly recommended to follow instructions given in the EMP strictly at the sensitive

locations. These impacts are temporary in nature and inconvenience is mainly for the

neighbouring people.

6 Will the Project lead to risks of

contamination of land or water from

releases of pollutants onto the ground or

into surface waters, groundwater or

coastal wasters?

Yes Low

Stock piling of material will lead to washing away of soil and may increase turbidity and TSS

(Total Suspended Solids) in road side drainage and nearby canals/streams and wetlands

temporarily during the construction. This is relevant for the Ch. 2+800 to 5+600 where the

road stretch traversed through lagoon ecosystem.

Construction activities in the proposed road stretch may also involve excavation and storage

of soil, which might increase erosion risk of top soil layers and cause siltation during wet

weather, if engineering best practices not adopted during construction.

On the other hand, proper construction practices like soil compaction and stabilization,

turfing, maintaining naturally stable slopes, etc. will improve soil stability, reducing erosion

risk and siltation effects during the construction phase and in the aftermath of

projectcompletion.

It is noted that sensitive fish species are found in the lagoon wetland habitats of the project

area, hence care should be exercised to control turbid matter contaminating lagoon wetland

habitats as a consequence of erosion laden with silt, sediment or any other colloidal material.

The specific recommendations for embankment protection and enhanced drainage along the



road stretch directly exposed to the waterfront targeting silt control as designed by RDA are

important to be adhered to.

7 Will the project cause localized flooding

and poor drainage during construction

Is the project area located in a flooding

location?

Yes Low

The project area is traversed through lowlands and lagoon area (Ch. 0+000~2+100and Ch.

2+800 and Ch. 5+600), may face flood risks in Heavy rainy seasons

Construction Phase:

Raised embankments and raised finish levels, stock piling of construction debris and other

materials, excavations in cut and fill sections, etc., may block existing drainage flow paths,

causing flow stagnation leading to localized inundations on temporary basis. However,

ensuring proper construction practices like provision of improved drainage network,

maintaining naturally stable slopes, etc. will improve drainage conditions, reducing flood risk

during the construction phase and in the aftermath of project completion.

During Operation:

Lack of routine maintenance may lead to silting of drains/culverts and cause local inundation/

overtopping of drain.

8 Will there be any risks and

vulnerabilities to public safety due to

physical hazards during construction or

operation of the Project?

Yes Low

Construction phase:

The proposed improvements involves widening at two critical locations at the Puloli

Methodist Mission Tamil Mix School (Ch. 0+200) andVarani Central Collage (Ch. 10+360).

These two locations are critical due to heavy pedestrian and vehicular movement in school

days. All the safety measures deployed in "Best Engineering Practices" need to be adopted

during the construction.

In General, disturbance to pedestrians, motorcyclists and motorists may be very likely on a

temporary basis due to traffic congestions. Safety issues in terms of injuries due to

construction work, drilling and blasting operation using heavy machinery could be



anticipated. However, such incidences can be avoided with proper precautions exercised on

health and safety aspects.

Operation phase:

During the operation phase, a smooth traffic flow can be expected and particularly due to

correction of undesirable curves traffic problems and potential accidents that are prevailing at

present can be overcome.

After rehabilitation and establishment of proper signage system, the road stretch will be

mostly clear of obstacles. Therefore, motorists and cyclists tend to travel faster, perhaps

recklessly.

9 Are there any transport routes on or

around the location which are susceptible

to congestion or which cause

environmental problems, which could be

affected by the project?

Yes Low

Throughout the road trace, there are several major and minor roads. It is likely to cause

temporary congestion on those roads during construction near the entrances. Creation of dust

and noise are the potential environmental impacts which are temporary in nature.

Due to the temporary closure of the roads during asphalt overlay the traffic would be diverted

to nearby roads making the traffic volume of those roads increased. However, there are many

connecting roads so that the impactscan be easily mitigated. Only a very few dwelling units

will be affected depending on the time of excavation.

It is likely to cause temporary congestion on those roads during construction near the

entrances. Potential environmental impacts would be creation of dust and noise during

construction which is temporary in nature.

Trucks which transport material and movement of other heavy vehicles used for road

construction will contest the local roads along transport routes.

10 Are there any routes or facilities on or

around the location which are used by

the public for access to recreation or

other facilities, which could be affected

by the project?

Yes Low

Similar to above item 9; They will be affected due to traffic built up if the project site is not

properly managed.Use of road to access commercial establishments and residential areas may

be temporarily affected but will not be completely cut off.



11 Are there any areas or features of high

landscape or scenic value on or around

the location which could be affected by

the project?

Yes Moderate – High

The topography of the area has created several areas of high value scenic areas (along the

lagoon area) but there will be no impact as the project will not disturb adversely to the view.

These aesthetically pleasing areas can be better viewed after road construction and that it will

create a positive impact.

12 Are there any other areas on or around

the location which are important or

sensitive for reasons of their ecology e.g.

wetlands, watercourses or other water

bodies, the coastal zone, mountains,

forests which could be affected by the

project?

Yes Low

The proposed road stretchtraverse through the lagoon area. Thus the negative effectsfrom the

constructions stage being there would be lowand completely mitigated if mitigatory measures

proposed in Table 7b are adopted during construction.

13 Are there any areas on or around the

location which are used by protected,

important or sensitive species of fauna or

flora e.g. for breeding, nesting, foraging,

resting, migration, which could be

affected by the project?

Yes The lagoon area (Ch. 2+800 and Ch. 5+600) provides habitat for several endemic and native

faunal and floral species. Hence care should be exercised to prevent washing away of

material laden with silt, sediment or any other colloidal material that causes high turbidity in

surface runoff.

Where the embankments are steep and prone to erosion, as mentioned above, low levels of

impacts could occur but these impacts are generally mitigatable.

14 Is the project located in a previously

undeveloped area where there will be

loss of green-field land

NO No such undeveloped green fields are encounteredin this area.

15 Will the project cause the removal of

trees in the locality? Yes Low

In areas where road improvements are planned, a few trees would need to be removed. In the

sections where there is a necessity to have safety measuresalso some trees have to be

removed. Theeffects from tree removal are minimum and it is recommended to follow

migratory measures as outlined in 7b.

Trees found in below mentioned chainages along the transect, especially those located within

the proposed walkway and shoulders,might disturb the construction activities. However, the



proposed construction activities can be carried out while preserving the trees and it is

recommended to incorporate existing trees worth retaininginto the overall layout of the

proposed design, wherever it is safe and practical, to provide armature and established

appearance.

16 Are there any areas or features of historic

or cultural importance on or around the

location which could be affected by the

project?

Yes Low

The selected road stretch traverse through the 14.2 km distance along the small townships

villages, paddy and other agricultural lands, temple

premisesincludingThittiveramTtakaiAmmalKovil(Ch. 10+700), EruwanPulleiarKovil (Ch.

12+740).However temporary inconvenience is expected for visitors due to potential traffic

generation noise and dust, particularly during weekends when a large number people visit

these religious places.

17 Are there existing land uses on or around

the location e.g. home gardens, other

private property, industry, commerce,

recreation, public open space,

community facilities, agriculture,

forestry, tourism, mining or quarrying

which could be affected by the project?

Yes Low

Present land use of the area is mixed along the road (commercial, industrial, residential etc.)

and agriculture and home garden type uses in interior areas. The project will not create any

significant negative impacts that would change the land use character of the area

Commercial establishments along the road, particularly at main junctions such as Kodikamum

(Ch. 14+100), Varani(Ch.8+460), Puloli (1+040) and Manthikai Junction will be affected due

to creation of traffic congestions and dust which will make the customers distracted. However

such impacts are of temporary nature that can be minimized by the deployment of best

engineering practices.




location which are densely populated or

built-up, which could be affected by the

project?

Yes Low

Construction Period

A very few locations along the road trace are comparatively densely populated (Kodikamum

(Ch. 14+100), Varani (Ch.8+460), Puloli (1+040) and Manthikai Junction). However they

will not be significantly affected by the project activities as except for a few uses others are

located outside the road reservation. However noise, dust and traffic congestion would be

potential impacts during construction period which are of temporary nature.

Operation Period

During the operation period due to improvements to the road network, it is likely that

motorists will speed up which will create potential accidents. However deployment of

adequate traffic management systems can overcome such potential impacts.


location which are occupied by sensitive

land uses e.g. hospitals, schools, places

of worship, community facilities, which

could be affected by the project?

Yes Low

Puloly Methodist Mission Tamil Mixed School, Varani North GTM and Varani Central

Collage are the main schools located on this road trace.

There are two main places of worship such as ThittiveramTtakaiAmmalKovil (Ch. 10+700),

EruwanPulleiarKovil (Ch. 12+740).

However since these sensitive land uses particularly schools and temples attract a large

number of people (school children, teachers, parents, and general community) there exist a

potential danger particularly in the morning and evening hours and also inconvenience due to

creation of dust and noise.


location which contain important, high

quality or scarce resources e.g.

groundwater, surface waters, forestry,

agriculture, fisheries, tourism, minerals,


Yes Low

Habitats connected with lagoon area along the trace may be affected due to surface runoff

bringing in additional loading of suspended particles together with high levels of bituminous

material, oil and grease during construction.

Part of paddy fields also could be affected due to siltation from eroded material.However,

ensuring construction best practices may reduce the risk of contamination of agricultural

lands, hence effects are low risk.



The areas along the lagoon contain water front scenic value (Bird watching Site) and tourist

interest. However at present such value is not optimized. The project will not involve in

creating negative impact on this scenic value.

21 Are there any areas which are already

subject to pollution or environmental

damage e.g. where existing legal

environmental standards are exceeded,


No No such areas along the selected road stretch
