Consent to Establishment has also been granted by Haryana State Pollution Control Board vide
HSPCB/Consent/: 2827414GUNOCTE190984 dated 08/02/2014. (Attached as Annexure
I(a) & Annexure I(b)). For the balance 103 acres, the Ansal API is now applying to the
Hon’ble SEIAA seeking environment clearance as an Expansion Project.
Regarding, the current applied expansion project, it is informed that various land owning
companies and individuals have entered into development agreements with Ansal API for
development and construction of the residential plotted colony. It is like a land pooling
arrangement by a private sector real estate developer. Since, the land has been contributed
willingly by the land owners, there is no issue of displacement of persons or rehabilitation
contrary to the case of compulsory acquisition by Government agencies.

SEWAGE TREATMENT TECHNOLOGY
FAB TECHNOLOGY
Sewerage System
An external sewage network shall collect the sewage from all units, and flow by gravity to the
sewage treatment plant.
Following are the benefits of providing the Sewage Treatment Plant in the present
circumstances:
Reduced net daily water requirements, source for Horticultural purposes by utilization of
the treated sullage.
Reduced dependence on the public utilities for water supply and sewerage systems.
Sludge generated from the Sewage Treatment Plant shall be rich in organic content and
an excellent fertilizer for horticultural purposes.

(d) C.O.D. : <100 mg/l
(e) Total Suspended Solids : <10 mg/l
c. Treatment Technology
The technology is based on attached growth aerobic treatment followed by clarification by a tube
settler. Lime will be dosed in for suppression of foaming tendencies. The clarified water will be
filtered in a pressure sand filter after dosing of coagulant (alum) for removal of unsettled
suspended impurities. This water will be passed through an activated carbon filter for removal of
organics. The filtered water from ACF is then chlorinated & stored in the flushing tank.
The attached growth fluidized aerobic bed reactor (FAB) process combines the biological
processes of attached & suspended growth. It combines submerged fixed film with extended
aeration for treatment of the sullage.
The sullage after screening is collected in an equalization tank. The equalization tank is required
for preventing surges in flow & facilitating equalization of characteristics over the entire quantity
of effluent in a given time. A provision for pre-aeration is made in the equalization tank in order
to ensure mixing & to prevent the sewage from going septic.
The equalized sewage is then pumped into the FAB reactor for biological processing. The water
enters the bottom of the reactor & flows up through the fixed film media which grossly enhances
the hydraulic retention time & provides a large surface area for growth of biological micro –
organisms. The FAB reactor is aerated by fine pore sub – surface diffusers which provide the
oxygen for organic removal. The synthetic media floats on the water & the air agitation ensures
good water to micro-organism contact.
The FAB treatment is an attached growth type biological treatment process where in, the
majority of biological activity takes place on the surface of the PVC media. Continuous aeration
ensures aerobic activity on the surface of the media. Micro – organisms attach themselves on the
media & grow into dense films of a viscous jelly like nature. sullage passes over this film with
dissolved organics passing into the bio-film due to concentration gradients within the film.
Suspended particles & colloid may get retained on this sticky surface where they are

Conceptual Plan
pg. 10
decomposed into soluble products. Oxygen from the aeration process in the sullage provides
oxygen for the aerobic reactions at the bio-film surface. Waste products from the metabolic
processes diffuse outward & get carried away by the sullage or air currents through the voids of
the media.
The aerated effluent passes into a tube deck settler for clarification. The theory of gravity tube
settler system is that the carrier fluid maintains laminar flow in the settling media at specified
maximum viscosity. These two parameters of a carrier fluid, flowing through a hydraulic
configuration, will determine the velocity gradients of the flow, the height of boundary layer at
the inclined surface and the residence time within the media.
The carrier fluid must be viscous Newtonian, exhibiting a Reynolds number of less than 1000
and preferably, a number under 400. The laminar flow, through the inclined tubes, will produce
velocity gradients sufficiently large to form an adequate boundary layer, where the velocity of
fluid approaches zero. Boundary layers are necessary in functioning tube settlers, to allow
suspended solids to separate from the viscous carrier fluid. Under gravitational forces, they will
settle to the hydraulic surface of the tube and subsequently from the clarifier media.
Since the tubes are inclined at 60 degrees, solids settled on the tubes are continually discharged
down. This downward rolling action increases particle contact and hence further agglomeration,
which increases the sludge settle ability. Studies show that these agglomerated sludge particles
can have a settling rate in excess of ten times the settling rate of the individual floc particles in
the influent. These heavy agglomerated masses quickly slide down the 60 degree inclined tube
and settle at the bottom of the tank.
At the bottom of the Tubedeck, where the sludge leaves the Tube surface, the larger
agglomerated captures smaller particles in the upcoming stream. This solid contact phenomenon
greatly enhances the capture efficiency.
Stages of Treatment: The treatment process consists of the following stages:
Equalization

RAIN WATER HARVESTING
The storm water disposal system for the project shall be self-sufficient to avoid any
collection/stagnation and flooding of water. The amount of storm water run-off depends upon
many factors such as intensity and duration of precipitation, characteristics of the tributary area
and the time required for such flow to reach the drains. The drains shall be located near the
carriage way along either side of the roads. Taking the advantage of road camber, the rainfall run
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 12
off from roads shall flow towards the drains. Storm water from various plots/shall be connected
to adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 168
rainwater harvesting pits at selected locations, which will catch the maximum run-off from the
area.
1) Since the existing topography is congenial to surface disposal, a network of storm water
pipe drains is planned adjacent to roads. All building roof water will be brought down
through rain water pipes.
2) Storm water system consists of pipe drain, catch basins and seepage pits at regular
intervals for rain water harvesting and ground water recharging.
3) The peak hourly rainfall of 45 mm/hr shall be considered for designing the storm water
drainage system.
Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak
hourly rainfall has been considered as 45 mm/hr. The recharge pit of 3 m diameter and 3.5 m
depth is constructed for recharging the water. Inside the recharge pit, a recharge bore is
constructed of adequate diameter and depth. The bottom of the recharge structure will be kept 4
m above the ground water level. At the bottom of the recharge well, a filter media is provided to
avoid choking of the recharge bore. Design specifications of the rain water harvesting plan are as
follows:
Catchments/roofs would be accessible for regular cleaning.
The roof will have smooth, hard and dense surface which is less likely to be damaged
allowing release of material into the water. Roof painting has been avoided since most
paints contain toxic substances and may peel off.
All gutter ends will be fitted with a wire mesh screen and a first flush device would be
installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags
and paper pieces will get arrested by the mesh at the terrace outlet and to prevent
contamination by ensuring that the runoff from the first 10-20 minutes of rainfall is
flushed off.
No sewage or sullage would be admitted into the system.
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana

pg. 13
No sullage from areas likely to have oil, grease, or other pollutants has been connected to
the system.
Calculations for storm water load (Existing + Expansion)
Roof-top area = Ground Coverage = 778147 m2
Green Area = Total green area – water body = 286028 m2
Paved Area = 60425 m2
Runoff Load
Roof-top Area = 778147 × 0.045 × 0.8
= 28013 m3/hr
Green Area = 286028 × 0.045 × 0.1
= 1287 m3/hr
Paved Area = 60425 × 0.045 × 0.75
= 2040 m3/hr
Total Runoff Load = 28013 + 1287 + 2040 m3/hr
= 31340 m3/hr
Taking 15 minutes Retention Time, Total volume of storm water = 31340/4
= 7835 m3
Taking the effective dia and depth of a Recharge pit 3 m and 4 m respectively, Volume of a
single Recharge pit = π r2h = 3.14 × 1.5 × 1.5 × 4 = 28.26 m3
Hence No. of pits required =7835/28.26 = 277.24 Say 277 Pits.
Total of 277 Rain Water Harvesting pits is required for artificial rain water recharge within the
project premises out of which 136 nos. of pits have to be constructed during Existing phase and
the balance 141 in the new / expansion phase.

ENVIRONMENT MANAGEMENT PLAN
An Environmental Management Plan (EMP) will be required to mitigate the predicted adverse
environmental impacts during construction and operation phase of the project and these are
discussed in later subsections.
EMP for Air Environment
Construction Phase
To mitigate the impacts of dust during the construction phase of the project, the following
measures are recommended for implementation:
A dust control plan
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 24
Procedural changes to construction activities
Dust Control Plan
The most cost-effective dust suppressant is water because water is easily available on
construction site. Water can be applied using water trucks, handled sprayers and
automatic sprinkler systems. Furthermore, incoming loads could be covered to avoid loss
of material in transport, especially if material is transported off-site.
Procedural Changes to Construction Activities
Idle time reduction: Construction equipment is commonly left idle while the operators
are on break or waiting for the completion of another task. Emission from idle equipment
tends to be high, since catalytic converters cools down, thus reducing the efficiency of
hydrocarbon and carbon monoxide oxidation. Existing idle control technologies
comprises of power saving mode, which automatically off the engine at preset time and
reduces emissions, without intervention from the operators.
Improved Maintenance: Significant emission reductions can be achieved through
regular equipment maintenance. Contractors will be asked to provide maintenance
records for their fleet as part of the contract bid, and at regular intervals throughout the
life of the contract. Incentive provisions will be established to encourage contractors to
comply with regular maintenance requirements.
Reduction of On-Site Construction Time: Rapid on-site construction would reduce the
duration of traffic interference and therefore, will reduce emissions from traffic delay.
Operation Phase
To mitigate the impacts of pollutants from DG set and vehicular traffic during the operational
phase of the Colony, following measures are recommended for implementation:
DG set emission control measures
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 25
Vehicular emission controls and alternatives
Greenbelt development
Diesel Generator Set Emission Control Measures
Adequate stack height will be maintained to disperse the air pollutants generated from the
operation of DG set to dilute the pollutants concentration within the immediate vicinity.
Hence no additional emission control measures have been suggested.
Vehicle Emission Controls and Alternatives
During construction, vehicles will be properly maintained to reduce emission. As it is a
group housing project, vehicles will be generally having “PUC” certificate.
Footpaths and Pedestrian ways: Adequate footpaths and pedestrian ways would be
provided at the site to encourage non-polluting methods of transportation.
Greenbelt Development
Increased vegetation in the form of greenbelt is one of the preferred methods to mitigate
air and noise pollution. Plants serve as a sink for pollutants, act as a barrier to break the
wind speed as well as allow the dust and other particulates to settle on the leaves. It also
helps to reduce the noise level at large extent. The following table indicates various
species of the greenbelt that can be used to act as a barrier.

10.2.2 EMP FOR NOISE ENVIRONMENT
Construction Phase
To mitigate the impacts of noise from construction equipment during the construction phase on
the site, the following measures are recommended for implementation.
Time of Operation: Noisy construction equipment would not be allowed to use at night time.
Job Rotation and Hearing Protection: Workers employed in high noise areas will be employed on
shift basis. Hearing protection such as earplugs/muffs will be provided to those working very
close to the noise generating machinery.
Operation Phase
To mitigate the impacts of noise from diesel generator set during operational phase, the
following measures are recommended:
Adoption of Noise emission control technologies
Greenbelt development
Noise Emission Control Technologies

The DG set room will be provided with acoustic enclosure to have minimum 25 dB(A)
insertion loss or for meeting the ambient noise standard whichever is on higher side as per E
(P) Act, GSR 371 (E) and its amendments. It would be ensured that the manufacturer
provides acoustic enclosure as an integral part along with the diesel generators set. Further,
enclosure of the services area with 4 m high wall will reduce noise levels and ensure that
noise is at a permissible limit for resident of the site and surrounding receptors.
Greenbelt Development
The following species can be used, as in a greenbelt, to serve as noise breakers:
Acacia auriculiformis
Anona squamosa
Acacia farnesiana
Achras sapota
Adenanthera pavonina
Aegle marmelos
10.2.3 EMP FOR WATER ENVIRONMENT
Construction Phase
To prevent degradation and to maintain the quality of the water source, adequate control
measures have been proposed. The following management measures are suggested to protect the
water source being polluted during the construction phase:
Avoid excavation during monsoon season
Care would be taken to avoid soil erosion
Common toilets will be constructed on site during construction phase and the waste
water would be channelized to the septic tanks in order to prevent waste water to
enter into the water bodies
Any area with loose debris within the site shall be planted
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 28
To prevent surface and ground water contamination by oil and grease, leak-proof
containers would be used for storage and transportation of oil and grease. The floors
of oil and grease handling area would be kept effectively impervious. Any wash off
from the oil and grease handling area or workshop shall be drained through imperious
drains
Collection and settling of storm water, prohibition of equipment wash downs and
prevention of soil loss and toxic release from the construction site are necessary
measure to be taken to minimize water pollution
All stacking and loading area will be provided with proper garland drains, equipped
with baffles, to prevent run off from the site, to enter into any water body.
Operation Phase
In the operation phase of the project, water conservation and development measures will be
taken, including all possible potential for rain water harvesting. Following measures will be
adopted:
Water source development.
Minimizing water consumption.
Promoting reuse of water after treatment and development of closed loop systems for
different water streams.
Water Source Development
Water source development shall be practiced by installation of scientifically designed
Rain Water Harvesting system. Rainwater harvesting promotes self-sufficiency and
fosters an appreciation for water as a resource.
Minimizing Water Consumption
Consumption of fresh water will be minimized by combination of water saving devices
and other domestic water conservation measures. Further, to ensure ongoing water
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 29
conservation, an awareness program will be introduced for the residents. The following
section discusses the specific measures, which shall be implemented:
Domestic and Commercial Usage
Use of water efficient plumbing fixtures (ultra flow toilets, low flow sinks, water
efficient dishwashers and washing machines). Water efficient plumbing fixtures uses
less water with no marked reduction in quality and service
Leak detection and repair techniques.
Sweep with a broom and pan where possible, rather than hose down for external
areas.
Meter water usage: Implies measurement and verification methods.
Monitoring of water uses is a precursor for management.
Horticulture
Drip irrigation system shall be used for the lawns and other green area. Drip irrigation
can save 15-40% of the water, compared with other watering techniques.
Plants with similar water requirements shall be grouped on common zones to match
precipitation heads and emitters.
Use of low-angle sprinklers for lawn areas.
Select controllers with adjustable watering schedules and moisture sensors to account
for seasonal variations and calibrate them during commissioning.
Place 3 to 5 inches of mulch on planting beds to minimize evaporation.
Promoting Reuse of Water after Treatment and Development of Closed Loop
Systems
To promote reuse of waste water and development of closed loop system for waste water
segregation. Two wastewater schemes are suggested, namely:
1) Storm Water Harvest 2) Waste water recycling.
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 30
Storm water harvest as discussed in earlier, will be utilized for artificial recharge of
ground water sources; and waste water will be reused on site after treatment.
Treated waste water will be used for landscaping, flushing, DG set cooling and
rest will be discharged to municipal sewer. Following section discuss the scheme
of waste water treatment.
Waste Water Treatment Scheme
Proponent will treat the waste water of the Group Housing in well designed sewage
treatment plant of capacity 4700 KLD based on FAB technology.
Storm Water Management
Most of the storm water produced on site will be harvested for ground water recharge.
Thus proper management of this resource is a must to ensure that it is free from
contamination.
Contamination of Storm Water is possible from the following sources:
Diesel and oil spills in the diesel power generator and fuel storage area
Waste spills in the solid / hazardous waste storage area
Oil spills and leaks in vehicle parking lots
Silts from soil erosion in gardens
Spillage of sludge from sludge drying area of sewage treatment plant
A detailed storm water management plan will be developed which will consider the
possible impacts from above sources. The plan will incorporate best management
practices which will include following:
Regular inspection and cleaning of storm drains
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 31
Clarifiers or oil/separators will be installed in all the parking areas. Oil / grease
separators installed around parking areas and garages will be sized according to
peak flow guidelines. Both clarifiers and oil/water separators will be periodically
pumped in order to keep discharges within limits
Covered waste storage areas
Avoid application of pesticides and herbicides before wet season
Secondary containment and dykes in fuel/oil storage facilities
Conducting routine inspection to ensure cleanliness
Provision of slit traps in storm water drains
Good housekeeping in the above areas
EMP FOR LAND ENVIRONMENT
Construction Phase
The waste generated from construction activity includes construction debris, biomass from land
clearing activities, waste from the temporary make shift tents for the labors and hazardous waste.
Following section discuss the management of each type of waste. Besides waste generation,
management of the topsoil is an important area for which management measures are required.
Construction Debris
Construction debris is bulky and heavy and re-utilization and recycling is an important strategy
for management of such waste. As concrete and masonry constitute the majority of waste
generated, recycling of this waste by conversion to aggregate can offer benefits of reduced
landfill space and reduced extraction of raw material for new construction activity. This is
particularly applicable to the project site as the construction is to be completed in a phased
manner.
Mixed debris with high gypsum, plaster, shall not be used as fill, as they are highly susceptible to
contamination, and will be send to designated solid waste landfill site.
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 32
Metal scrap from structural steel, piping, concrete reinforcement and sheet metal work shall be
removed from the site by construction contractors. A significant portion of wood scrap will be
reused on site. Recyclable wastes such as plastics, glass fiber insulation, roofing etc shall be sold
to recyclers.
Hazardous waste
Construction sites are sources of many toxic substances such as paints, solvents wood
preservatives, pesticides, adhesives and sealants. Hazardous waste generated during construction
phase shall be stored in sealed containers and disposed off as per The Hazardous Wastes
(Management & Handling) Rules, 1989.
Some management practices to be developed are:
Herbicides and pesticide will not be over applied (small-scale applications)
and not applied prior to rain
Paintbrushes and equipment for water and oil based paints shall be cleaned within
a contained area and will not be allowed to contaminate site soils, water courses
or drainage systems
Provision of adequate hazardous waste storage facilities. Hazardous waste
collection containers will be located as per safety norms and designated hazardous
waste storage areas will be away from storm drains or watercourses
Segregation of potentially hazardous waste from non-hazardous construction site
debris
Well labeled all hazardous waste containers with the waste being stored and the
date of generation
Instruct employees and subcontractors in identification of hazardous and solid
waste
Even with careful management, some of these substances are released into air, soil and water and
many are hazardous to workers. With these reasons, the best choice is to avoid their use as much
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 33
as possible by using low-toxicity substitutes and low VOC (Volatile Organic Compound)
materials.
Waste from Temporary Makes Shift Tents for Labors
Wastes generated from temporary make shift labor tents will mainly comprise of household
domestic waste, which will be managed by the contractor of the site. The wastewater generated
will be channelized to the septic tank.
Top Soil Management
To minimize disruption of soil and for conservation of top soil, the contractor shall keep the top
soil cover separately and stockpile it. After the construction activity is over, top soil will be
utilized for landscaping activity. Other measures, which would be followed to prevent soil
erosion and contamination include:
Maximize use of organic fertilizer for landscaping and green belt development
To prevent soil contamination by oil/grease, leaf proof containers would be used
for storage and transportation of oil/grease and wash off from the oil/grease
handling area shall be drained through impervious drains and treated
appropriately before disposal
Removal of as little vegetation as possible during the development and re-
vegetation of bare areas after the project.
Working in a small area at a point of time (phase wise construction)
Construction of erosion prevention troughs/berms.
Operational Phase
The philosophy of solid waste management at the complex will be to encouraging the four R’s of
waste i.e. Reduction, Reuse, Recycling and Recovery (materials & energy). Regular public
awareness meetings will be conducted to involve the residents in the proper segregation and
storage techniques. The Environmental Management Plan for the solid waste focuses on three
major components during the life cycle of the waste management system i.e., collection and
transportation, treatment or disposal and closure and post-closure care of treatment/disposal
facility.

Collection and Transportation
During the collection stage, the solid waste of the project will be segregated into
biodegradable waste and non-biodegradable. Biodegradable waste and non
biodegradable waste will be collected in separate bins. Biodegradable waste will
be treated in the project premises by vermicomposting. The recyclable wastes will
be sent off to recyclabers. Proper guidelines for segregation, collection and
storage will be prepared as per MSW Rules, 2000 and amended Rules, 2008.
To minimize littering and odour, waste will be stored in well-designed containers/
bins that will be located at strategic locations to minimize disturbance in traffic
flow
Care would be taken such that the collection vehicles are well maintained and
generate minimum noise and emissions. During transportation of the waste, it will
be covered to avoid littering.

Disposal
With regards to the disposal/treatment of waste, the management will take the services of the
authorized agency for waste management and disposal of the same on the project site during its
operational phase.
EMP FOR ECOLOGICAL ENVIRONMENT
Construction activity changes the natural environment. But Residential colony also creates a
built environment for its inhabitants. The project requires the implementation of following
choices exclusively or in combination.
Construction Stage
Restriction of construction activities to defined project areas, which are ecologically
sensitive
Restrictions on location of temporary labor tents and offices for project staff near the
project area to avoid human induced secondary additional impacts on the flora and
fauna species
Cutting, uprooting, coppicing of trees or small trees if present in and around the
project site for cooking, burning or heating purposes by the labors will be prohibited
and suitable alternatives for this purpose will be made
Along with the construction work, the peripheral green belt would be developed with
suggested native plant species, as they will grow to a full-fledged covered at the time
of completion.
Operation Stage
Improvement of the current ecology of the project site will entail the following measures:
Plantation and Landscaping
Green Belt Development
Park and Avenue Plantation
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 36
The section below summarizes the techniques to be applied to achieve the above objectives:
Plantation and landscaping
Selection of the plant species would be done on the basis of their adaptability to the existing
geographical conditions and the vegetation composition of the forest type of the region earlier
found or currently observed.
Green Belt Development Plan
The plantation matrix adopted for the green belt development includes pit of 0.3 m × 0.3 m size
with a spacing of 2 m x 2 m. In addition, earth filling and manure may also be required for the
proper nutritional balance and nourishment of the sapling. It is also recommended that the
plantation has to be taken up randomly and the landscaping aspects could be taken into
consideration.
Multi-layered plantation comprising of medium height trees (7 m to 10 m) and shrubs (5 m
height) are proposed for the green belt. In addition creepers will be planted along the boundary
wall to enhance its insulation capacity.
Selection of Plant Species for Green Belt Development
The selection of plant species for the development depends on various factors such as climate,
elevation and soil. The plants would exhibit the following desirable characteristics in order to be
selected for plantation
1. The species should be fast growing and providing optimum penetrability
2. The species should be wind-firm and deep rooted
3. The species should form a dense canopy
4. As far as possible, the species should be indigenous and locally available
5. Species tolerance to air pollutants like SO2 and NOx should be preferred
6. The species should be permeable to help create air turbulence and mixing within the belt
Revision of Environment Clearance for expansion of Residential Plotted Colony named “ESENCIA/ VERSALIA” at Sector-67 & 67A, Gurgaon, Haryana
Conceptual Plan
pg. 37
7. There should be no large gaps for the air to spill through
8. Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces
9. Ability to withstand conditions like inundation and drought
10. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter)
11. Attractive appearance with good flowering and fruit bearing
12. Bird and insect attracting tree species
13. Sustainable green cover with minimal maintenance.
Parks and Avenue Plantation
Parks and gardens maintained for recreational and ornamental purposes will not only
improve the quality of existing ecology at the project site but also will improve the
aesthetic value.
Avenue Plantation
1. Trees with colonial canopy with attractive flowering
2. Trees with branching at 7 feet and above
3. Trees with medium spreading branches to avoid obstruction to the traffic
4. Fruit trees to be avoided because children may obstruct traffic and general movement
of public
10.2.6 EMP for Socio-Economic Environment
