Study Area
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 will be provided in the Map. 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. Monitoring will be done within the study area and as per CPCB guidelines. Primary data collection will be in one season.
3.1 Land Environment

The basic meteorological parameters such as wind speed, wind direction, Temperature, Humidity and Rain fall are pertinent to the air pollution studies are those governing the transport and diffusion of the pollutants in the atmosphere and it will be covered in EIA report. Base line data of air pollutant parameters extending an area of 10 km from the project site will be
monitored at 7 locations. Ambient air quality parameters namely PM 2.5 , PM 10 , Nitrogen dioxide, Sulphur dioxide and Carbon monoxide, Ozone, Pb, NH3, Benzene, Benzo alpha pyrene, Arsenic, Nickel will be analyzed as per Indian Standards 5182 method.
3.3 Noise Environment
Noise Level Study
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. 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 should be conducted in the study area while covering 10 km distance from the project site. Noise monitoring will be undertaken for 24 hours at each location. Using hand held instruments sound Pressure Level (SPL) measurements and the levels were measured at all locations, recording for 5 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 results will be produced as per the Noise Pollution (Regulation and Control) Rules 2000 – Ambient Air Quality Standards in respect of Noise.
3.4 Water Environment
Water quality
Water is a vital commodity for the survival of human beings, animals, and vegetation and also for the proper balance of the eco-system. As such any adverse impact on water quality due to the proposed construction will have serious consequences on the environment. Hence it is essential to study the water quality, water table, Rain water harvesting of the regime likely to b influenced by the project and allied activities as per TOR and MoEF, EIA Manual. The water quality of the study will be covered in EIA report. Sampling and Analysis
Water sampling is to determine the existing quality of ground water around the project area and also to assess the impact from the proposed project. Sampling will be done by following standard guidelines for physical, chemical and bacteriological parameters. Analysis will be carried out by following methods prescribed in “Standard Methods for the Examination of Water and Wastewater (21st Edition)”. Samples will be collected from surface water body and bore wells in the study area. The site selection was done taking into account the drainage pattern and locations prone to water contamination. seven water sampling locations will be selected around 10 km distance from the project site.
3.5 Rain Water Harvesting
Keeping in mind the importance of water and it scarcity it is proposed to conserve water by rainwater harvesting by which the subsoil water condition / moisture content is maintained / improved to a great extent. Also it is proposed to harvest rainwater from the terrace area by collecting the same in a rainwater collection sump of suitable capacity and re-used for domestic purposes with the provision of a filtration unit. And the rainwater collected from open paved and landscape area will be collected in the storm water drain which is connected to Rainwater recharging pit; will be included in EIA report in detail.

The run-off will be routed through recharge wells. 15 nos. of recharge wells are being proposed for rain water harvesting.
Details of Recharge Trenches: Trench maintained all along the boundary, the depth of the trenches will be around 1.00 m. It is planned to remove the entire impervious layer to facilitate rain water recharge. The width of the proposed trenches is 1.5 m. Pebbles of different size will be provided in an ascending order in the tank and a layer of sand will be provided on top of the filter media. The rain water flowing through the open land, paved area and green belt area will be used for recharging to ground water through the above said trenches.

Architectural design
Maximum utilization of solar light will be done. Maximize the use of natural lighting through design. The orientation of the buildings will be done in such a way that maximum daylight is available. The green areas will be spaced, so that a significant reduction in the temperature can take place.
Energy Saving Practices
Energy efficient lamps will be provided within the complex. Constant monitoring of energy consumption and defining targets for energy conservation. Adjusting the settings and illumination levels to ensure minimum energy used for desired comfort levels.
Behavioral Change on Consumption
Promoting resident awareness on energy conservation Training staff on methods of energy conservation and to be vigilant to such opportunities
Green Belt Development
It is proposed to have tree plantation along the periphery of the site and also to develop lawn and greenery inside the project area. The vegetation for the green belt will be selected from the native species adapted to the local environment. About 44540.99 Sqm of green area will be provided.
Landscaping has been taken care of in view of the environment and aesthetics of the surrounding areas. Stress has been laid on providing ample green areas in close conjugation to the hard areas in a manner, that the overall harmony and ambience is maintained. Landscaping takes into account the various aspects of the architectural design. Trees are proposed to be planted to form an integral part of the landscape plantation and their selection is based on their ability to provide shade, flowers and fragrance apart from their high-yielding growth pattern. The addition of shrubs, hedges and ground cover will add to the aesthetics and softness to the hard building surfaces.
