1 INTRODUCTION

1.1 BACKGROUND

Riverbank Developers Private Limited is constructing an integrated township

– Calcutta Riverside at Batanagar, Maheshtala, Ward No 27&28, Kolkata -

700140. The Environmental Clearance (EC) for the aforesaid project was

obtained from West Bengal State Level Environmental Impact Assessment

Authority (SEIAA) earlier vide Memo No. EN/1283/T-II-1/066/2008 dated

19/06/2008. The extension of the validity of the EC was sought in 2015 and

consequently provided vide Letter No. 49/EN/T-II-1/066/2008 dated 7th

January, 2016. Thus the validity of the extension of the EC has been extended

for another five years, i.e until 2018. A compliance report updating the project

status and the status of compliance to the conditions stipulated with the EC

accorded by SEIAA is being submitted every six month to West Bengal

Pollution Control Board and State Level Environmental Impact Assessment

Authority (SEIAA).

The Calcutta Riverside project comprises of an integrated township of

different units of residential, commercial, institutional and recreational

facilities on 262 acres of land. The ongoing project is located approximately 7

km away from Taratala. The project activities have been planned across 5

different phases in a span of 9 years between 2013 and 2022.

Calcutta Riverside is committed to developing an affordable living space and

has adopted modern technology, infrastructure to ensure that it is a

sustainable township. Calcutta Riverside would source surface water for the

township rather than groundwater or Municipal Water. It has installed

organic waste convertors and modular STP’s to treat its solid and liquid waste

to reduce the environmental footprint of the township.

The total built up area sanctioned as published in the EC provide by SEIAA,

West Bengal is 8,09,046.68 sq.m. Till date, Calcutta Riverside has completed

construction of 6,17,172.64 sq.m. Presently, Riverbank Developers Private

Limited proposes to undertake expansion of Calcutta Riverside. It is proposed

to increase the total built up area from 8,09,046.68 sq.m to 18,17,096.75 sq.m

and reallocation of approved plan for commercial and residential area. The

total ground coverage of built up area after the proposed expansion will not

exceed 40% of the total land area of Calcutta Riverside. Approximately, 60% of

total land area has been allocated for open space and utilized for roads, parks,

waterbodies, riverfront promenade, golf course, etc.

1.2 PROJECT SITE

The site is located in Ward No. 27 and 28, Maheshtala Municipality at

Batanagar. The site can be accessed from Taratala through Budge Budge

Trunk Road. The site is bounded by River Hooghly in North-Western end.

The site is surrounded by settlements of Haetpur, Purba Jagtala, Ward No. 25,

1.3 PROJECT FEATURES

1.3.1 Land Area

The proposed expansion is located in Calcutta Riverside (CRS)- An integrated

Township. The site has a land area of 1060268.15 m2 (106.03 ha). The existing

project of CRS is spread across 83,547.91 sq.m (8.3 ha). The proposed project is

expected to have a ground coverage of 91,492.05 sq.m (9.1 ha). The total bult-

up area of the existing project is 6,70,142.68 sq.m. Presently, CRS proposes to

additionally build 11,46,954.07 sq.m.

1.3.2 Existing Project of Calcutta Riverside

At present, CRS has completed few of the parcels of projects or will be

completed within a short time period. The project was assessed by SEAIAA,

West Bengal and consequently EC was provided in 2008 that was

subsequently extended until 2018. The brief description of the parcels is provided below.

1.4 PROPOSED PROJECT OF CALCUTTA RIVERSIDE

Presently, more than 80% of ground coverage is an open space. Based on

increasing market demand, CRS proposes to expand its township. Also, as per

earlier sanction plan, CRS had allocated 1,38,904 sqm of built up area for IT


7

SEZ. Due to market dynamics , the proposal for the project could not be

undertaken. CRS would thus propose for conversion of the above built-up

area for residential purpose. CRS now proposes to build additional parcels as

provided in Table 1.2.

1.7 TRAFFIC AND PARKING ARRANGEMENT

1.7.1 Road Connectivity

CRS can be accessed from Taratala through Budge Budge Trunk Road. An

elevated toll road of 6.85km is being built from Jinzirabazaar to Batanagar.

This will help ease traffic congestion and improve connectivity for the existing

as well future population. This project is being developed by Kolkata

Metropolitan Development Authority (KMDA) in Public Private Partnership

mode.

The nearest railway station is Nungi approximately 0.2km away from site

connecting Sealdah and Budge Budge. The nearest Airport is Netaji Subhas

Chandra Bose International Airport located approximately 25km (aerial

distance) from the site.

No change in vehicular movement plan is proposed and the movement will

remain same with main entry and exit through the east gate. However,

internal roads will be bult for accessing each parcel in the proposedexpansion

project. Moreover, Calcutta Riverside along with Kolkata Municipal

Development Authority is building an elevated corridor of 6.85km connecting

Jinzirabazaar to Batanagar is being built to cater to the total population at

Calcutta Riverside.

1.8 FIRE PROTECTION AND DETECTION SYSTEM

System Description

All hydrants are connected to pump and sump and ground level and also

connected to overhead tank and pump and roof level

Manual call point and hooters cum strobe available at the exits like

Fire extinguishers are in place as per IS requirements and type of fire

application.

Fire Signage’s at all buildings at floor level, entry exit and fire instructions

with emergency contact numbers

Portable Fire Extinguishers

The number and location of portable fire extinguishers depends on the size

and use of the building. Different types of Extinguishers such as Dry

Chemical Powder, Carbon-di-oxide and Water type Carbon di-oxide type

have been provided at the different locations;

1.9 SITE DRAINAGE PLAN

The storm water drainages established for the Project site is as per the

approved Master Plan, which is aligned to the existing drainage pattern of the

study area. Natural slope of the site is towards the River Hooghly as well.

River Hooghly flows through the North-West side of the project.

As part of storm water management, the Project site undertakes the following

best management practices:

Regular inspection and cleaning of storm water drains;

Oil - water separators (oil traps)will be installed in all the parking

areas;

Cover waste storage areas;

Avoid application of pesticides and herbicides before monsoon season;

Conduct routine inspections to ensure cleanliness;

Provide silt traps in storm water drains.

1.10 LANDSCAPE PLAN

Calcutta Riverside has an open space of approximately 885228.19 sq.m i.e

more than 83.49% of the total area. This is more than 60% as stipulated by the

Environmental Condition and provided in 2008. Dedicated Green area is

developed in approximately 212053.63 sq.m, i.e 20% of the project site. The

natural bodies existing in the site has been retained and reshaped where

required.

In addition to the other landscape interventions, the project proponent is

developing a 9 hole golf course (for the residents) of area (27.95acre approx.)

at the centre of the township. Significant number of buildings has been

designed around the Golf course to get the best possible view. Same practice

shall be followed in the expansion components as well. Playground, Fair

ground and Football grounds have also been developed within the

township.The vegetation and open space of Calcutta Riverside is provided in

Figure 1.4.
