3.0 DESCRIPTION OF THE ENVIRONMENT
Baseline studies are carried out to provide a detailed description of the existing ecosystem, landscape, infrastructure, cultural heritage and urban environment. A baseline study describes the initial state of the environment within the selected boundaries of the study area.
A description of the existing environmental status of the study area with reference to the prominent environmental attributes is thus described in detail. The existing environmental setting is considered to adjudge the baseline conditions which are described with respect to climate, hydro-geological aspects, atmospheric conditions, water quality, soil quality, vegetation pattern, ecology, socio-economic profile, land use, places of archaeological importance etc.
The chapter incorporates the baseline data generated in the study area during March 2018 to May 2018 and secondary data collected from various Government and Semi-Government organizations. The details about the existing environmental values are projected at each section in the form of the maximum and minimum values at each location and the measurement duration. The area of the study covers 10 km radius around the proposed site. To make the process easier, the entire zone is divided into two, namely the core zone comprising of the proposed construction project area and the buffer zone covering the remaining areas covered under the 10 km radius.
The guiding factors for the present baseline study are the MoEF&CC’s requirements for the Environmental Impact Assessment notification and local regulations and directives. The studies were conducted by considering the following:
• The various environmental attributes were divided into primary and secondary studies. Primary attributes such as air environment, water, soil, biological environment were assessed by conducting field studies, on-site monitoring; and • Secondary attributes such as land use studies, geology, hydrological characteristics, and socio-economic environment have been assessed by literature review of previous studies conducted and from various government publications.
The scoping and the extent of data generation were formulated with interdisciplinary team discussions, criteria questions and professional judgment. The baseline studies started with site visits and survey in the study area for fixing the monitoring locations for the primary data generation. As a secondary data source, various government agencies were approached for getting information and relevant data.

3.2 Air Environment
3.2.1 Meteorology Meteorological factors have a direct bearing on the dispersion and dilution of pollutants/contaminants, discharged into the atmosphere with consequent impact on air Environment. Micro-meteorological properties of the atmosphere govern the concentration of pollutants and its variations with time and location with respect to their sources. Micro- meteorological measurements are therefore essential to fit the air quality observations in a dispersion model, with a view to arrive at the ground level concentration at various distances in down-wind direction for various pollutants. The nearest authoritative meteorological recording station is maintained by the Regional Meteorological Center at Numgambakkam, Chennai. The basic meteorological parameters pertinent to the air pollution studies are those governing the transport and diffusion of the pollutants in the atmosphere and they are listed below:
• Wind speed • Wind direction • Temperature • Humidity and • Rain fall
3.2.2 Methodology of Sampling
Micro-meteorological station was installed in the site with the objective of recording wind direction and speed, Temperature, Humidity and Pressure. The data thus collected from the station represent the prevailing micro-meteorological aspects of core and buffer zone. Wind direction was observed using wind vanes and velocity by using Anemometer at hourly intervals and data was plotted as wind roses. The maximum and minimum relative humidity for each sampling location was also recorded along with temperature by using wet and dry bulb thermometer. The rainfall was estimated using rain gauge.
3.2.3 Data Analysis
The observed temperature range in the area varied from 19o C to 39o C. The relative humidity normally varied between 50% and 85% while the minimum wind speed is 4 km per hour and the maximum wind speed is 12 km per hour. The predominant wind direction observed during the study period was Southeast direction. Wind rose at site for the study period is depicted in below Figure 1-6. Average rainfall at site is 1100 mm recorded in earlier years.

Average rainfall at site is 1100 mm recorded in earlier years.
3.2.7 Air Environment
General
The atmosphere as such is always being in a dynamic state. A wide range of solids, liquids and gases are emitted from both the natural and man-made sources. These substances, called
Eco Services India Pvt. Ltd., Chennai – 600 032 Page_
Environmental Impact Assessment Report Dugar Housing Limited pollutants, will be easily carried away and travel to long distances, through air, disperses and reacts with other particles and among themselves. Due to this chemical and physical reaction of the pollutant, air pollution will be caused.
“Air Pollution" is defined as any disturbances caused in the Atmospheric Air quality, which may cause injury to human beings, plants (Vegetation) and animals, apart from interference to comfortable living. The level of air pollution depends upon the magnitude of the activities in the particular area as well as the meteorological conditions. Though buildings are not a major contributor to air pollution, they often contribute to pollutants into the air during both construction and operational phases.
The sources of air pollution during construction and operational phases of the project are as follows:
• Construction Phase: Includes site clearance and preparation, infrastructure development, building construction and other related activities. • Operational phase: Includes emissions from vehicular movement and diesel generators, and negligible emissions from sewage and solid waste handling and disposal.
To assess the base line status, Air quality monitoring was done at different locations in the study area. The ambient air monitoring locations have been selected based on the meteorological data obtained from Regional Meteorological Centre (RMC), Chennai. This will reveal clearly the levels of the pollutants at different localities, which will be useful to the project to have the basic scale of the existing Environment.
3.2.8 Sampling Location For the purpose of the study five locations as shown in Table-3.3 were selected to assess the baseline environmental quality with respect to the air environment. The locations are depicted in Figure-3.2. The choice of the location is based on the importance of the place with respect to industrial, traffic and other human related activities.

Environmental Impact Assessment Report Dugar Housing Limited
• PM 10
• PM 2.5
• Sulphur dioxide (SO 2)
• Oxides of Nitrogen (NO X) • Carbon Monoxide (CO)
The ambient air samples were collected in the month of March, April and May 2018.
3.2.10 Method of Analysis
The air samples are analyzed as per standard methods specified by Central Pollution Control Board (CPCB) and IS-5182.
PM 10 , PM 2.5 present in ambient air are sucked through the cyclone. Coarse and non-respirable dust is separated from the air stream by centrifugal forces acting on the solid particles. These separated particulates fall through the cyclone's conical hopper and gets collected in the sampling cap placed at the bottom. The fine dust (PM 2.5 Microns) forming the respirable fraction of the PM 10 passes the cyclone and is retained by the filter paper. A tapping is provided on the suction side of the blower to provide suction for sampling air through a set of impinges. Samples of gases are drawn at a flow rate of 0.2 liters per minute (Lpm).
PM 10 and PM 2.5 have been estimated by gravimetric method. Modified West and Gaeke method (IS-5182 Part-II, 1969) has been adopted for estimation of SO 2. Jacobs-Hochheiser method (IS- 5182 Part-IV, 1975) has been adopted for the estimation of NOX. Glass tubes have been used to collect the grab samples of carbon monoxide (CO). The CO levels were analyzed through Gas Chromatography.

3.3 Noise Level Study
The physical description of sound concerns its loudness as a function of frequency. Noise in general is sound, which is composed of many frequency components of various loudness, distributed over the audible frequency range. Various noise scales have been introduced to describe, in a single number, the response of an average human to a complex sound made up of various frequencies at different loudness levels. The most common and universally accepted scale is the A weighted Scale which is measured as dB (A). This is more suitable for audible range of 20 to 20,000 Hz. The scale has been designed to weigh various components of noise according to the response of a human ear. The impact of noise sources on surrounding community depends on:
• Characteristics of noise sources (instantaneous, intermittent or continuous in nature). It can be observed that steady noise is not as annoying as one, which is continuously varying in loudness; • The time of day at which noise occurs, for example high noise levels at night in residential areas are not acceptable because of sleep disturbance; and • The location of the noise source, with respect to noise sensitive land use, which determines the loudness and period of exposure.
The environmental impact of noise can have several effects varying from Noise Induced Hearing Loss (NIHL) to annoyance depending on loudness of noise. The environmental impact assessment of noise from construction activity, vehicular traffic can be undertaken by taking into consideration various factors like potential damage to hearing, physiological responses, and annoyance and general community responses. Noise survey has been conducted in the study area while covering four zones viz., residential, industrial, commercial and sensitive zones. Noise monitoring has been undertaken for 24 hours at each location. The main objective of noise monitoring in the study area is to establish the baseline noise levels and assess the impact of the total noise generated by the operation of the activities around it.
3.3.1 Identification of Sampling Locations
A preliminary survey has been undertaken to identify the major noise generating sources in the study area. Noise at different noise generating sources has been identified based on the activities in the village area, ambient noise due to small-scale industries, traffic and noise at sensitive areas. The noise monitoring has been conducted for determination of noise levels at 4 locations in the study area. The noise levels at each location were recorded for day and night. The location details of noise monitoring are given in Table-3.5 and shown in Figure 3.3.
3.3.2 Method of Monitoring
Using hand held instruments Sound Pressure Level (SPL) measurements and the levels were measured at all locations, recording for 10 minutes at each hour was taken for 24 hours continuously. The day noise levels have been monitored during 6 am to 10 pm and night levels during 10 pm to 6 am at all the sampling locations covered in the study area.

The surface runoff during the construction period was directed into the drains separately provided for this purpose and disposed off through the external storm water drains.
Operation Phase
Keeping in mind the importance of water and its scarcity the rainwater harvesting installed by which the subsoil water condition during the operation phase of the project. The runoff from the roof top after suitable pretreatment is being harvested and reused. The treatment system for the rainwater harvesting are consist of sand, gravel and boulders. This will reduce the drawl of groundwater especially on rainy days
Rain Harvest Pit - Roads / pavements and landscape
The rain water harvesting facility that are provided in our project based on the soil lithology study conducted at the project site and the same has been vetted by EIA Consultant Organization accredited by NABET wherein an approved Expert on Hydrogeology has vetted the design. The details of the designs are furnished below;
Soil Infiltration Rate :
The infiltration rate is the velocity or speed at which water enters into the soil. It is usually measured by the depth (in mm) of the water layer that can enter the soil in one hour. An infiltration rate of 15 mm/hour means that a water layer of 15 mm on the soil surface will take one hour to infiltrate. In dry soil, water infiltrates rapidly. This is called the initial infiltration rate. As more water replaces the air in the pores, the water from the soil surface infiltrates more slowly and eventually reaches a steady rate. This is called the basic infiltration rate. The infiltration rate depends on soil texture (the size of the soil particles) and soil structure (the arrangement of the soil particles).
Basic Infiltration Rates (Hydraulic Conductivities) of Soils: Soil Type Basic Infiltration Rate (K-values – m/day) Clay surface 0.01-0.2 Deep clay layer 10 -8 – 10 -2 Loam 0.1-10 Fine sand 1-5 Medium sand 5-20 Coarse sand 20-100 Gravel 100-1000 Sand and Gravel 5-100 Clay, Sand and Gravel 0.001 – 0.1 (Reference: Annexure – 4.1, EIA Guidance Manual, Building, Construction, Townships and Area Development Projects, Published by Ministry of Environment and Forests, Govt. of India, February 2010)

(Normally 50 % of total quantum of rainfall in catchment area should be considered to beside the number and size of percolation tanks - Ref. Chapter 2, Rain Water Harvesting, Pg. no. 11, in Rain Water Harvesting and Conservation Manual by CPWD, GOI) 50 % of total quantum of rainfall in catchment area : 285 Cu.m/d No. of recharge pits required : 285 Cu.m/d / 22.29 Cu.m/d : 12 no. of pits. No. of recharge pits provided : 26 nos.
Internal Storm Water Drain 100 % of total quantum of rainfall in catchment area is considered for calculation of drainage system to avoid flooding within the project site. (Ref. Appendix A 3.1, Computation of Storm Runoff and Design of Storm Sewer) Estimated runoff from project site : 285 Cu.m/d = 0.003299 Cu.m/sec Cross section of Drainage System : 0.6 Sq.m Carrying capacity of the open flow channel is based on Manning's equation as follows: Q = A * V,
Where, Q = Discharge in Cu.m/sec A = Area in Sq.m V = Velocity in m/sec
V = where, n = Manning's Coefficient (For concrete finished surface = 0.016) R = Hydraulic Radius in m (R = A/P, where P = Wetted Perimeter in m) S = Channel slope in m/m For the residential development, n = 0.013 A = 0.6 Sq.m (Width = 0.6 m, Depth = 1m) P = (2 x 0.6) + 1 = 2.2 m R = A/P = 0.6/2.2 = 0.27 m S = 1/300 = 0.00333 V = 1.855 m/sec Q = A x V = 0.6 x 1.855 = 1.113 Cu.m/sec Thus, the provided internal storm water drainage system is adequate to handle to runoff from the project site. During abnormal rains, the excess runoff after storage and recharge will be disposed off through the external storm water drains. The external storm water drain starts from the project site boundary has its outfall into Cooum River. Hence the excess runoff from project site would not result in any conditions which may eventually lead to flooding / submergence in and around the project area.

3.5 Biological Environment
The demands of an ever – increasing human population have jolted us into the realization that our environment is precious, finite, and deteriorating. This realization came upon us at the very time great numbers of people were experiencing tremendous benefits from our technologies, which have often resulted in significant losses to the natural environment. The environment is composed of non-living and living factors forming a network of inter-relationships that are easily disturbed by people. Within the larger challenge of sustainable development lies the even greater challenge of the requirement of environmentally sound equitable economic growth. Conservation, protection and preservation of the environment have been the cornerstone of the Indian ethos, culture and traditions. It has been enshrined in our constitution also, which is one of the first in the world to recognize the importance of environmental conservation. As the constitution provides the framework for creating a welfare State, it is incumbent on the authorities that the finite natural resources of the country be optimally utilized without adversely affecting the health of the people or the environment.

The distribution of flora and fauna in the given area represents the Biological portion of the environment that includes, what is present in the study area, its value, and its response to impacts, description of community uniqueness, the dominant species, and an evaluation of rare or endangered species.
The above studies were carried out using the standard methods prescribed by John G. Rau and David C. Wooten 1980.
3.5.6 Ecology
The detailed ecological assessment of the study area has been carried out with the following objectives: • Identification of flora and fauna and their biodiversity within the study area • Preparation of checklist of species which also includes endangered, endemic and protected (both floral and faunal categories) • Evaluation of impact of proposed project on flora and fauna of the area.
Methodology
The ecological status of the study area has been assessed based on the following methodology:
• Primary field surveys to establish primary baseline of the study area • Compilation of information available in published literatures and as obtained from Forest survey of India, Botanical Survey of India and Zoological Survey of India.
The flora and fauna studies were carried out in 5 study sites representing the entire study area of 10 km radius around the proposed construction site. The study area has been divided into core zone i.e., 2.5 km radius from the outer boundary of the construction site and buffer zone i.e., the outer 7.5 km radius.
3.5.7 Flora
The Study of flora involved intensive sample survey of vegetation in the project site and other locations applying standard methods. To examine the trees and shrubs, quadrants of 25 x 25 m and for herbs 2 x 2 m were laid. In each of the larger quadrants (i) Species (ii) their number, and (iii) Girth at Breast Height (GBH), were measured. (Chaturvedi and Khanna, 1982).
Abundance, relative abundance, density and relative density of each species diversity and evenness for each of the Zones were calculated using the numerical data (Ludwig and Reynolds 1988, Lande 1996, Smith and Wilson 1996). The standard statistical analysis, the normal frequency diagram and distribution of plants in the study area were analyzed using the procedures of Raunkiaer, 1934. The analysis carried out as per Raunkiaer’s law of frequency classes provides the information on the Heterogeneity and Homogeneity of plants and its pattern

The above five strata were found in the entire field monitoring stations with equal representation. This shows the life – forms of the area and its amplitude. This also reflects the light intensity, temperature, and organic content of the soil and other factors of the area.
PERIODICITY (PHENOLOGY) Periodicity refers to the regular seasonal occurrence of various processes such as photosynthesis, growth, pollination, flowering and ripening of fruits and seeds; and the manifestations of the processes, such as formation of leaves, elongation of shoots, appearance of flowers and dissemination of seeds. This results from the inherent genetic characteristics of each species, under the influence of a particular combination of the environmental conditions. Periodicity means particularly the recurrence at certain times of these processes and their manifestations, while phenology refers more to the appearance of the manifestations at certain seasons of the year, rather than to their cyclic nature. The characteristic species of the scrub forests and other elements are in flowering and noted with fruiting stage and are well adapted to the seasonal changes in the physical environment. Periodicity and Phenology is perfectly maintained in the study area among the various species recorded during the survey.
VITALITY (VIGOR) Vitality relates to the condition of plant and its capacity to complete the life cycle, while vigor refers more specifically to the state of health or development within a certain stage. The studies carried out at different sites reveals that the plant species found in the area are well- developed plants, showing various stages of growth which regularly complete their life cycle.

LIFE FORM The life form in a broad sense is meant the characteristic vegetative appearance such as the size, shape, branching etc. The life form observed in the study area reveals that there are several communities ranging from open grassland, succulent perennials ( Euphorbia sps), aquatic herbs ( Eichhornia crassipes, Nelumbo nucifera, Nymphaea pubescens ) and small annual plants. The kinds of life forms, the number of individuals of each kind and their spacing gives a good structure to the community. HABITAT FORMS The habitat forms of the study area can be broadly classified into three classes in the order of their dominance. (a) Xerophytes : Euphorbia. Antiquorum, Euphorbia royleana, Euphorbia tirucalli, (b) Mesophytes : Pongamia pinnata, Thespisia populnea, Ficus sps. (c) Hydrophytes : Eichhornia crassipes, Nelumbo nucifera, Nymphaea pubescens, Typha angustifolia. The xerophytes group is classified on the basis of its ability to endure drought, plants belonging to the xerophytic group and were not seen in the core zone. Mesophytes include sun and shade plants and Hydrophytes include submerged, floating and amphibious plants.
QUANITITATIVE CHARACTERISTICS The quantitative characteristics are the one, which can be readily measured. It includes density of the plants, basal area dominance and frequency.
RELATIVE DENSITY AND DOMINANCE The relative density and dominance values of different species found in the study are shows that the dominant plants of various sites have a high percentage value of density and dominance. These values are incorporated in calculating the Importance value Index.
IMPORTANCE VALUE INDEX (IVI) The Importance Value Index (IVI) is an expression used to summarize the plant data; it is desirable to use as many values as possible. The density of one species gives an idea of the number of plants in a stand; the dominance gives an idea of relative degree to which a species predominate a community by its numbers, size or biomass. Species that exerts the greatest control or influence in the community are called ‘dominants’. Plant dispersion over an area or within a community is another parameter; frequency is the measure of species in a series of plots. Frequency expresses the proportion of equal size sample plots in which at least one plant of that species occur relative to the number of plots taken. Thus the IVI of species is the combination of relative density, relative dominance and relative frequency values of a species added together to obtain a single expression. Importance value Index (IVI). The Importance value allows quantitative comparison of each species in a stand with the other species in the stand, or allows comparison of the species in one stand with species in other stands.

Status of flora as per Raunkiaer’s frequency classes
Raunkiaer classified the occurrence of species in an area into five classes of frequency Class – A (1 to 20%), Class – B (21 to 40%) Class – C (41 to 60%) Class – D (61 to 80%) and Class – E (81 to 100). The normal distribution of the frequency percentages derived from such classification is expressed as A>B>C=D The ecological status of vegetation was calculated using the Raunkiaer’s normal frequency diagrams and the results are given in Table and depicted in Fig. for core zone.

Conclusions were made as per the Raunkiaer’s law on the basis of the following (a) Whether the distribution of plants fulfils the Raunkiaer’s law of frequency diagram, if it does not fulfill then it indicates that the distribution of plant community is affected by human impact. (b) A comment on the impact – whether the distribution is Homogeneous or Heterogeneous. The result shows that, the distribution is Heterogeneous, in Core and Buffer zones thus fulfilling the Raunkiaer’s law. The Heterogeneity observed among the plant community in the Core and Buffer zones reveals that, the characteristic species of scrub fore sts are dominant and occupies the class E. They were recorded in all the stands used for this investigation showing the highest frequency; there is a wide distribution of plant species observed in various stands. 100% Frequency were not recorded for many characteristic species except for Prosopis juliflora and Acacia nilotica . Though, these two species are dominant, the distribution of vegetation is heterogeneous in nature. The Heterogeneous status indicates that there is no human impact in the core and buffer zones . Habitat pattern The environmental conditions with one kind of habitat exhibit variation from spot to spot. The ecological amplitude of one or more of the species under consideration delimits the extent of a habitat. The habitat pattern is associated with the environmental conditions; this has been very well manifested in the study area. Though the topography is plain with some undulations here and there the presence of scrub elements and deciduous species clearly shows the habitat pattern in this area. Changes The Changes from the initial establishment of vegetation on an area to the terminal climax community are continuous. However, a given group of species will reach a peak of dominance at a certain stage of the sequence. Then as the dominance of this group decreases, the dominance of another group of species will develop to a maximum. This kind of change in dominant species have been observed in the study area, among different transects. The Change from one stage to the subsequent st age may be especially prominent where there is a change of life form of the dominant species. There is usually an increase in productivity per unit area, in Eco Services India Pvt. Ltd., Chennai – 60600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited organic mass per unit area because of the presence of the larger life forms, in complexity and diversity of species and life forms, and in the relative stability and homogeneity of the populations. The soil and other aspects of the habitat will also undergo progressive development. Climax The Climax community is the one in which no further directional change takes place under the prevailing environmental conditions. This is the terminus of habitat and vegetation development. The climax community of the study area is Azadiracta indica and the grass like Ariztida hystrix. The climax community is in the steady state with respect to productivity structure and population, with the dynamic balance of its populations dependent upon its respective site. The community has a maximum diversity, relative stability and homogeneity of the species populations within and between the stands of a given climax type. The given climax type is characterized in appearance within and between stands. Discussion on vegetation analysis The interpretations based on the above analysis and the floristic composition reveals that, the vegetation encountered in the study area is termed as the original characteristic of Thorn forests / Scrub forests, Southern tropical dry deciduous forests, Northern mixed dry deciduous forests, and tropical dry ever green forests. The core zone comprises of Residential, commercial and agricultural and fallow lands. The types of forest / vegetation found in the study area are Open scrub along with the representative elements of the deciduous and dry ever green forest types. Physiognomically it occurs in the shape of scrub woodland or thicket; the latter may be dense or discontinuous. Floristically it is distinguished by some characteristic and preferential species (Braun Blanquet, 1932), exclusively or mostly confined to this vegetation type, in relation to the types described by champion (1936) and champion and Seth (1968). Status of the plants There is no endangered, threatened, or rare species of plants recorded in the study area. Eco Services India Pvt.

Most of the villages in the buffer zone have got educational facility up to primary level. In the entire area, the primary, middle and high schools, colleges and polytechnics are listed below in Table 3.9. Table-3.9 List of Educational Institutions S.No. Description Total 1 Primary school 36 2 Middle school 42 3 High school 68 4 Higher secondary school 29 5 Medical College 2 6 Arts and Science Colleges 27 7 Engineering Colleges 29 8 Polytechnics 11 Water Supply Water supply to these wards is supplied by the local body/through tanker Lorries. The other major resource is groundwater from wells and tube wells spread all across the area. The study reveals that all the villages have adequate drinking water facilities from ground water sources that include wells, deep bore wells, water supplied by Govt. Agencies and hand pumps. Transport The development of transport and communications system is an important factor for the proposed development. The availability and coverage of transport and communication system invites industries to cluster in one area, even if some other difficulties are there. The City is well connected by roads with the adjoining urban center, Chennai. The Kancheepuram and Thiruvallur district has a combination of two modes of transport within the city. Metropolitan Rapid transport system (MRTS) and Metropolitan transport Corporation buses. The city also has a fleet of three wheelers for hire, called Auto rickshaws. They are the most economical mode of hired transport. There is a choice of independent taxis and private tourist cabs in the city. Power Electricity is one of the most vital infrastructure inputs. Fairly well developed infrastructure and comfortable power situation offer significant competitive advantages to Tamilnadu. All the villages in the zone have electric power supply, which is mainly used for Domestic purposes. While some portions in the study area utilize the electric power supply for Agricultural use and Industrial uses. Eco Services India Pvt.

Religion, Fairs and Festivals Various religious groups consisting of Hindus, Muslims, and Christians inhabit the study area. Hindus and Christians are the predominant religious groups followed by Muslims. The population consists of many communities and castes that live in good harmony in the study area. Fairs and festivals are held in the different parts of the study area throughout the year. Traffic Analysis Traffic assessment of the road abutting the project site (i.e., Kamarajar Street) was carried out to estimate the peak traffic load. The existing traffic load during the morning and evening peak hours were studied and the vehicle counts were categorized under different heads. The different categories of vehicular load were converted to PCU equivalents by applying the respective “M” factors. The peak traffic load in terms of PCUs was arrived and the incremental traffic due to the project was worked out. This projected traffic load (incremental) was compared with the standard carrying capacity of the existing road. It was observed that the ratio between Volume and Capacity (V/C ratio) was well within the limits. Hence the impact of the traffic due to the proposed project is insignificant. The detail of the traffic assessment is presented below. Traffic Survey: Project: M/s.

The Administrative unit within 10 km radius zone comprises of parts of following Taluks in Kanchipuram district. The study area is 10 Km Radius from the project site boundary and forms part of the Survey of India Top sheet Nos. 66 C-1. Eco Services India Pvt. Ltd., Chennai – 600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited As per the EIA guidelines the study area has been divided into Core zone and Buffer zone which is about 10 km radius from the boundary of the proposed project site area. The current land use has been assessed as it forms the basis for any developmental planning. Methodology Information of land use and land cover is important for many planning and management activities concerning the surface of the earth (Agarwal and Garg, 2000). Land use refers to man's activities on land , which are directly related to land (Anderson et al., 1976). The land use and the land cover determine the infiltration capacity. Barren surfaces are poor retainers of water as compared to grasslands and forests, which not only hold water for longer periods on the surface, but at the same time allow it to percolate down. The terms ‘ land use’ and ‘land cover’ (LULC) are often used to describe maps that provide information about the types of features found on the earth’s surface (land cover) and the human activity that is associated with them (land use). These are important parameters for number of environmental related development projects associated with inland and coastal areas. It is necessary to have information on existing land use / land cover but also the capability to monitor the dynamics of land use resulting out of changing demands. Satellite remote sensing is being used for determining different types of land use classes as it provides a means of assessing a large area with limited time and resources. However satellite images do not record land cover details directly and they are measured based on the solar energy reflected from each area on the land. The amount of multi spectral energy in multi wavelengths depends on the type of material at the earth’s surface and the objective is to associate particular land cover with each of these reflected energies, which is achieved using either visual or digital interpretation. In the present study the task is to study in detail the land use and land cover in and around the project site respect to the development of Residential Township Project. The study envisages different LULC around the project area and the procedure adopted is as below. Eco Services India Pvt.

The description of the land use categories for 10 km radius and the statistics are given for core and buffer zones separately. Interpretation Technique: Standard on screen visual interpretation procedure was followed. The various Land use / Land cover classes interpreted along with the SOI topographical maps during the initial rapid Eco Services India Pvt. Ltd., Chennai – 600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited reconnaissance of the study area. The physiognomic expressions conceived by image elements of color, tone, texture, size, shape, pattern, shadow, location and associated features are used to interpret the FCC imagery. Image interpretation keys were developed for each of the LU/LC classes in terms of image elements. July 2012 FCC imagery (Digital data) of the study area was interpreted for the relevant land use classes. On screen visual interpretation coupled with supervised image classification techniques are used to prepare the land use classification. 1) Digitization of the study area (10 km radius from the proposed site) from the top maps 2) Satellite Data Selection: In the present study the IRS –P6 satellite image and SOI topo sheet of 66C-4 have been procured and interpreted using the ERDAS imaging software adopting the necessary interpretation techniques. 3) Satellite data interpretation and vectorisation of the resulting units 4) Adopting the available guidelines from manual of LULC mapping using Satellite imagery (NRSA, 1989) 5) Field checking and ground truth validation 6) Composition of final LULC map 7) The LULC Classification has been done at three levels where level -1 being the broad classification about the land covers that is Built-up land, agriculture land, waste land, wet lands, and water bodies. These are followed by level –II where built-up land is divided into towns/cities as well villages. The Agriculture land is divided into different classes such as cropland, Fallow, Plantation, while wastelands are broadly divided into, Land with scrub and without Scrub and Mining and Industrial wasteland. The wetlands are classified into inland wetlands, coastal wetlands and islands. The water bodies are classified further into River/stream, Canal, Tanks and bay. In the present study level II classification has been undertaken. The satellite imagery of 10 km radius from the project site is presented – Plate – 1 Field Verification: Field verification involved collection, verification and record of the different surface features that create specific spectral signatures / image expressions on FCC. In the study area, doubtful areas identified in course of interpretation of imagery is systematically listed and transferred on to the corresponding SOI topographical maps for ground verification. In addition to these, traverse routes were planned with reference to SOI topographical maps to verify interpreted LU/LC classes in such a manner that all the different classes are covered by at least 5 sampling areas, evenly distributed in the area. Ground truth details involving LU/LC classes and other ancillary information about crop growth stage, exposed soils, landform, nature and type of land degradation are recorded and the different land use classes are taken.

Generally, the environmental impacts can be categorized as either primary or secondary. Primary impacts are those, which are attributed directly by the project and secondary impacts are those, which are indirectly induced and typically include the changed patterns of social and economic activities by the project. The operational phase of the project comprises of various activities each of which will have impact on some or other environmental parameters. Various impacts during the operational phase and the environmental parameters have been studied to estimate the impacts on environment. The identification and details on impact of the project activity on each of the above environmental attributes are discussed below. 4.2 Identification of impacts The identification of impacts is important as it leads to the other elements such as quantification and evaluation of impacts. Although a number of non-projects related impacts have been identified while describing the existing (baseline) environmental status, it is necessary at this stage to identify the types of the potential impacts which might be caused by the proposed development. Many techniques are available for identification of impacts. In case of this project, the "Matrix Method" was adopted, which involves an understanding of the cause-condition- effect relationship between an activity and environmental parameters. It is very useful as gross screening tool for impact identification method. This method has been basically advantageous in recognizing the series of impacts that could follow from the proposed activities. The idea was to account for the project activity and identify the types of impacts that could initially occur. This process was repeated until all possible types of impacts were identified. With this method the potential impact of the proposed project has been identified.

There is no major pollutant envisaged from the project development. It is likely that the air quality may be affected slightly due to the emissions from the vehicular movement. The emission from DG sets will be very negligible since it will be used only during power cut in the necessary area. However in the case of DG sets the stack will be properly designed and installed to meet the stipulations of CPCB. These emissions will be insignificant and the environmental pollutant levels will be maintained within the prescribed limits. Hence there shall not be any adverse impact on the air environment around the residential building complex. 4.5 Impact on Ambient Noise There will not be any major impact from noise. This is because no equipment or other infrastructure facility in the project generates noise more than 50-60 dB (A). However, the only noise generation source is the DG set. They adopted adequate steps to maintain the noise levels within the prescribed limits. For the same all the DG facilities are sound insulated provided with inbuilt acoustic enclosure. 4.5.3 Traffic Noise Traffic would be induced during operation phase of the project. In the operation phase, vehicular parking is being provided in the basement, ground floor and first floor of the building where noise levels are expected to increase substantially during the peak hours due to starting, idling and roaring of vehicles. Eco Services India Pvt. Ltd., Chennai – 600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited 4.6 Impact on Land Environment No blasting is envisaged during construction phase of the project. The rehabilitation and resettlement issues are not involved in the project. Furthermore the existing environmental conditions of the project site reveal that the land is not contaminated or polluted. Also the impact due to exploitation of ground water is insignificant in the site due to the sourcing of water from other sources during the operation phases. Hence there will not be any adverse impact on the surrounding land use during the operation phase. 4.7 Impact on Water Resources The project requires 176 KLD of fresh water to meet the entire common and per capita requirements and required water will be sourced from local body or through private tankers. The total quantity of wastewater generation is estimated to be 145 KLD. No impact from wastewater, this is because the sewage generated is being treated and recycled within the project components for flushing and gardening. Therefore, surface and subsurface contamination due to treated wastewater is not envisaged. 4.8 Impacts Due To Solid Waste Disposal The solid waste generated from the project are being collected daily and moved to a common temporary storage facility by the staff dedicated for waste collection. The segregated biodegradable waste will be treated in Organic Waste Converter (OWC) and manure will be used for green belt development. The non biodegradable waste is being handed over to the recyclers. 4.9 Impacts on Ecological Resources No wastewater will be discharge into the surface water stream. Hence, there will not be any impact on the aquatic ecology. Also the proposed project is to be located in an earmarked primary residential zone, which does not have any natural park or sanctuary or forest area in the immediate vicinity. The flora and fauna pattern in the area will not be disturbed due to the project. Hence the overall impact on ecological resources due to proposed project is likely to be insignificant. Moreover the entire project area has been landscaped with variety of indigenous plants. 4.10 Impact on Traffic Levels Based on the vehicular density observed during the traffic survey conducted on the main roads around the project site, the existing infrastructure is capable of taking up additional traffic loads. Also the increase in traffic is being easily handled by the existing as well as the future improvements in the transportation infrastructure. Hence there will not be any impact on the traffic pattern and density. Eco Services India Pvt. Ltd., Chennai – 600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited 4.11 Impacts on Socio Economic Environment The residential development complex will be open to members of all communities and castes. The above measure will encourage mixing of different caste people for their respective festivals and occasions. This will improve the social welfare and brotherhood among the various communities and castes. The state of the art facilities provided in the development to cater the needs of the people working in the development which would be able to provide healthy working atmosphere. Hence it is obvious to assume that the activities of the development will produce some positive impacts in the socio-economic status of the area. 4.11.1 Public Health and Safety As the project is only a Residential development complex and all the construction activities are confined to the project site, no health related impact would be envisaged within the project area. The people engaged in the construction activities is not directly exposed to dust generation, which is likely to cause health related impact. Appropriate mitigation measures like spraying of water has been adopted to minimize dust emission in the construction site. Laborers are provided with suitable Personal Protective Equipment (PPE) as required under the health and safety norms. Regular health checkups were organized. 4.11.2 Positive Impact The project will facilitate maximum participation of the local work force for construction process; this will benefit the local economy, improvement in economic activity and enhancement in earning opportunities for the local population. The operation of the project and other allied facilities will improve the employment opportunities. The project will provide direct and indirect employment. The employment will have positive impact on the local economy thereby increasing the quality of life. The proposed rainwater recharge facility will augment the ground water level in the project area. The proposed project will also improve the aesthetics of the area due to the development of modern buildings. Air emissions are observed during the operation phase of the project. The air emissions are being reduced by ensuring smoother flow of traffic within the premises by better traffic management plans. This includes the internal roads of suitable widths, provided medians at the entry and exit points, provided sufficient parking areas, provided sufficient pedestrian walkways and the internal roads in such a way that the destination can be reached by the shortest possible distance. Alos trees all through the boundaries of the site has been provided and along the either side of the internal roads. This will reduce the particulate matters from being transported to the nearby areas. The air emissions from the Diesel Generators is being controlled by using low sulphur content high speed diesels, periodic maintenance of DG sets as per the defined schedule of manufacturer and by providing adequate stack heights as prescribed by CPCB. The stack height for the DG sets are calculated based on the CPCB guidelines as shown below; Eco Services India Pvt. Ltd., Chennai – 600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited The main source of air emissions from the proposed residential complex is from proposed 2 nos. of 500 kVA and will be used only during TNEB power failure. To control the air emissions from these D.G sets, adequate stack height is provided to release the exhaust flue gases into the atmosphere at a height at which efficient dispersion takes place. Since the DG sets are operated only during power failure, the emission is not continuous and hence the impact due to these emissions is insignificant. The stack height for the DG sets are calculated based on the CPCB guidelines as shown below: The stack height for the DG sets are calculated based on the CPCB guidelines as shown below; Stack Height Design Calculation for 500 KVA (2 Nos.) Generator Set H = h + (0.2) (kVA) 0.5 = 16.2 + 0.2 (250) 0.5 = 16.2+ 3.2 = 20.67 m = 21 m (say) Where, H = Total height of stack in meters from ground level h = height of the building in meters The stack height required as per CPCB norms is 21 m above the ground level and the same height will be provided. 4.12 Noise Control and Management 4.12.1 Construction Phase The noise generated from the construction equipments was reduced through proper maintenance of all the equipments which are involved in construction activities, confining the construction activities only during the day time and providing barricades all around the project area. The adverse impacts of noise especially on workers were reduced by providing ear muffs to the workers in high noise zones. Noise control systems such as equipment foundation pads, dampeners, silencers and acoustic enclosures was used for individual units as per the requirement to minimize the noise & vibration. Operating vehicles only during non peak hours and implementing better traffic management plan was significantly reduced the noise generated due to the congestion caused by the movement of vehicles involved in transportation. 4.12.2 Operation Phase The increase in the ambient noise levels due to the vehicle transportation will be controlled by the development of the green cover all along the internal roads and by implementing better traffic management plans inside the site premises. The better traffic management plans will significantly reduce the noise generated due to the congestion caused by the movement of vehicles. Eco Services India Pvt. Ltd., Chennai – 600 032 Page_ Environmental Impact Assessment Report Dugar Housing Limited The goal for generator noise control is to promote hearing conservation while reducing noise levels to protect employees and other personnel from hearing loss and increase personnel safety within the facilities.
