EXECUTIVE SUMMARY

1.1. Identification of Project:

Sardar Vallabhbhai Patel International Airport (SVPIA) (IATA: AMD, ICAO: VAAH) is an

international airport serving the cities of Ahmedabad and Gandhinagar in Gujarat, India. It

is named after Sardar Vallabhbhai Patel, the 1st Deputy Prime Minister of India.

In fiscal year 2017-18, it handled about 9.2 million passengers making it the eighth-busiest

airport in terms of passenger traffic in India. The airport is an operating hub for Air Odisha

and Blue Dart Aviation. The airport also serves as a focus city for Air India, GoAir, IndiGo

and Jet Airways.

As part of the airport modernization process, the AAI proposed to construct a new air

traffic control (ATC) tower cum technical block. The same will be done due to operational

requirement as approach funnel of runway (23) is not clearly visible from existing ATC

Tower

The area earmarked for the proposed construction is about 9840.00 m2 within the existing

airport premises. There is no additional requirement of land for the proposed construction

works. The construction work will be done in the land abutting the existing airport. Thus,

the same requires prior Environmental Clearance under the provisions of EIA Notification,

2006 and subsequent amendments. The same shall be categorized under item 7 (a) of

Schedule - Gazette Notification as Category A project.

1.2. Project Brief:

The project involves construction of new ATC tower cum technical block. The old ATC

building will be dismantled. The total area of the existing SVPI airport is 928.59 acres,

while the area earmarked for the proposed construction is 9840 sq. m. The details of the

proposed building are summarized as under:

activities, adverse impacts of sedimentation.

Oil & Grease Roads, driveways, parking lots etc.

Oil & Grease trap will be provided to remove oil & grease, suspended matter, and ensure the quality of water.

Storm water control and rain water harvesting will be done as per the standards laid

down by CGWA & BIS. Following measure will be adopted for the same:

Construction Sequencing: Construction sequencing (involves disturbing only part of a

site at a time to prevent erosion from dormant parts) has been done at site. Grading

activities and construction are completed and soils are effectively stabilized on one part

of the site before grading and construction commence at another part.

Compost Blankets: A compost blanket is a layer of loosely applied composted material

placed on the soil in disturbed areas to reduce storm water runoff and erosion. This

material fills in small rills and voids to limit channelized flow, provides a more

permeable surface to facilitate storm water infiltration, and promotes re-vegetation.

Post Construction Phase:

a. Design:

For good design of rainwater harvesting, following points are to be kept under

consideration:

• Ideal location with good ground slope.

• The location has adequate subsurface permeability of the aquifer to accommodate

maximum recharge of rainwater through injection well.

• Rate of filtration should exceed average rainfall intensity.

• Clogging of filtration media should be cleaned periodically.

• Ground water pollution does not take place.

b. Baseline:

The average annual rainfall (based on last 5 years rainfall data) at Ahmedabad station is

623 mm.

EIA purpose:

As per the EIA notification dated 14th September, 2006, it is mandatory for the proposed

activity to get Environmental Clearance (EC) before setting up any project or

expansion/modernization of any project. The detailed chart delineating the process is

given below:

Environmental Impact Assessment (EIA) is a well planned process to predict the

environmental consequences of any kind of development, which is a result of human

activities and to suggest appropriate measures in order to reduce adverse effects and also

to augment positive effects. The EIA procures a rational and ethical approach for

sustainable development. However, it is more scientific process because it not only tells

the past, present and the future consequences of on-going developments, but also

predicts the future events which are likely to change due to various reasons.

In terms of the EIA notification of the MoE&F dated 14th September 2006, the generic

PLANNING BRIEF

5.1 Planning Concept This is a planned airport development project to cater aviation demand as per Master Plan.

The construction of new ATC building cum Technical block is proposed. Other facilities such

as power, transportation and communication, social infrastructure facilities are already

available at project site as the proposed project lies within S.V.P.I. Airport, Ahmedabad.

5.2 Population Projection The general public at S.V.P.I airport, Ahmedabad will not be having any impact as this

building is to be used by only staff of existing ATC office.

5.3 Land use planning Land use has been categorized based on the following functional groups:

Airfield Dependent: Land uses with the highest location and area priority include those that

are fully within the airfield, or overlapping the airside-landside boundary.

Airport Supporting: Land uses with functional priority include those that are required for

the airport to function. Their location may be on the airside or landside but preferably within

the airport boundary.

Commercial: Land uses that are fully provide non-aviation revenues. These uses have

flexibility of location but should not interfere with the functional operation of Airfield

Dependent or Airport Supporting Land Uses.

Infrastructure & Open Space: These land use areas are determined by the needs of all the

land uses above. Since supporting infrastructure must be within the development areas the

first three groups determine the area required for this group. Open space includes those areas

remaining which cannot be developed.

5.4 Assessment of Infrastructure Demand (Physical & Social) Social Demand

On the basis of the preliminary site visit, the infrastructure demand in the nearby area is

assessed on the basis of need and priority:

The assessment will be identified in the socio economic survey, after the grant of TOR and

will be submitted at the time of final presentation regarding Environmental Clearance.
