ANALYSIS OF ALTERNATIVES The proposed project stretch is a single stretch from Ananthapuramu to Amaravathi alignment. For the alignment three possible options for development are suggested. The purpose of this chapter is to identify an Environmentally feasible alignment for 4/6 lane expressway between Amaravthi to Ananthapuramu. The assessment of Alternative alignment for the proposed expressway is very challenging task due to presence of Wildlife Sanctuaries, reserve forests, towns, villages, water bodies, homestead, agriculture lands, non-agriculture areas, built- up areas, Tin sheds etc. In order to choose the best alignment various alternatives were analysed using Environmental Impact Assessment Decision Support System (EIADSS). The EIADSS analysis of the same is explained in detail in successive sections. Alternative Analysis Using EIADSS Alternative analysis was done using Environmental Impact Assessment Decision Support System (EIADSS). The alternative analysis is mainly aimed to mitigate the adverse social & environmental impacts in the project and make technically feasible and economic & financially viable alternative. The EIADSS system assists decision-makers to opt for Alternative Routes in Railways /Highway projects. The criteria used for comparing the project alternative routes are not limited to the impacts of the project on the physical environment such as natural resources and biological life, but also include the impacts on socioeconomics, political affairs as well as financial and economics. Thus, method is flexible enough to account for the user’s preferences in weighing the main categories of impacts criteria. The first step behind the conceptual basis of the EIADSS was to identify the environmental criteria that are susceptible to change due to proposed project construction or operation, and then categorize these criteria under main headings. The physical factors that were known to be responsible for changing the criteria conditions were then identified. All the possible conditions of these factors were determined and compiled in a questionnaire. The Impact criteria are mainly categorized in to five groups (viz. Natural Resource Impacts, Ecological Impacts, Socio- Economic Impacts, Political Impacts, and Financial & Economic Impacts). The weightage percentage could be finalized using Data Capturing Instrument (DCI) and for the proposed road connectivity project of this nature, the weightage percentage is as follows.

Effects and probability of occurrence are moderate) Major Impact (the activity has a major effect under regular 6 (-)7 to operating conditions and leading to major breach of the statutory (-)10 regulations. Effects and probability of occurrence are extensive) The score of environmental aspects of each group was evaluated by using the ‘Environment Impact Score Instrument’.

Based on the highest marks scored, the project alternative shall be finalized. The three options for the alignment of Anantapur to Amaravathi are depicted from Figure 1 to 3.
