    Bay Scoping Results

    Operational Stage of Masterplan: Physio-chemical, Ecological environment & Socio-economic

    Construction and Intermediate Stages: Physio-chemical, Ecological environment & Socio-economic

    #2

    Agenda: NCICD Scoping Workshop

  • Goals of NCICD Stakeholder Consultation

    DHI

    The Objectives of the NCICD Stakeholder Scoping Workshop are:

    Present the scoping results (via GIS/spatial analysis)

    Obtain and document stakeholders feedbacks or concerns

    Include scoping outcome in TOR for SEA to ensure all environment and social impact are sufficiently addressed

  • DHI

    Overall Project Objectives

    Preliminary compilation of baseline data to allow for scoping analysis Preliminary Baseline Analysis

    Executing scoping analysis to identify key issues for coverage in the NCICD SEA Scoping

    The execution by the appointed SEA consultant Impact Evaluation and Reporting

    #4

    To prepare a SEA TOR, with preliminary scoping analysis, that will ensure that the appointed SEA expert conducts a NCICD SEA that is sufficient to uncover and mitigate major irreversible strategic issues related to the NCICD Masterplan.

  • Review of SEA Principles

    DHI

  • Step by Step

    DHI

    1. Scoping / baseline analysis Determination of key issues that should be considered in NCICD Analysis of key issues i.e. past trends, the current situation and likely future

    evolution if the plan or programme is not implemented

    2. Assessment of effects of the plan or programme on the key issues and development of mitigation measures (including monitoring scheme)

    3. Compilation of the TOR and scoping report

    #6

    4. Taking information generated for comprehensive SEA and explaining decision in publicly accountable manner

  • Relationship Between SEA & Planning

    DHI

    Planning analyzes and proposes development interventions SEA examines individual outputs of the planning process and it may propose

    any necessary amendments Optimally, SEA should be carried out in parallel with planning, when

    The lead process is the planning process, and SEA fits into the logic and steps of the planning process

    Thus, both processes can be seen as mutually reinforcing tools within one robust planning system for more sustainable development

    #7

  • NCICD Masterplan

    DHI

  • DHI

    Availability of Relevant Masterplan & Baseline Information

    What we have: General NCICD Masterplan Baseline data (physio-chemical, environment, socio-economic) from secondary

    data, previous DHI study in Jakarta, recent survey A basic understanding of autonomous developments

    What we dont have Certain detail regarding design and planning e.g.:

    Dike enhancement design, new sewage and water pipe design, inland water quality treatment, sea wall gates and pumping system, coastal habitat compensation

    Intermediate profiles and construction works/phasing What is possible?

    Scoping at conceptual level to identify key impacts related to the operational and construction phases of NCICD

  • DHI

  • NCICD Scoping Methodology

    DHI

  • Definition of a Strategic Issue for NCICD

    DHI #12

    Strategic environmental impacts (or issues) are those that can only be adequately assessed at the planning, policy, or program stage

    In relation to the NCICD a strategic sustainability issue is further defined in relation to:

    Cumulative impacts Interactive impacts Wide-scale impacts Eco-

    system

    Socio-economic

    Physico-chemical

  • Scoping Approach

    DHI

    The scoping aimed at identifying issues of strategic concern related to NCICD master planning

    Scoping sessions applied GIS / spatial data and analysis matrices a focus on utilizing

    Key baseline information Understanding autonomous development (i.e. planned reclamation and land use) Identifying potential environmental risks / issues, as per the an applied definition, from NCICD

    planning

    Stakeholder scoping feedback to obtain new insight/data and verify initial scoping findings

    Providing TOR and scoping report, for the appointed NCICD SEA expert

    #13

  • NCICD SEA Scoping Sessions

    DHI

    Review of key baseline information in studies and via spatial referenced maps Scoping was further organised in relation to:

    The Operational Phase (i.e. final configuration of Masterplan) The Construction Phase (e.g. construction works and intermediate profiles)

    Each phase was further categorised according to location of risks/issues, i.e. DKI Jakarta, Tangerang, Bekasi, and inside / outside of seawall (retention lake)

    strategic sustainability receptor categories, namely:

    1. Physic-chemical Coastal Dynamic Riverine and Drainage Sedimentation Water Quality

    2. Ecosystem Coastal Habitat Biodiversity

    3. Socio-economic Resource-utilization Human Health Livelihood

    #14

  • NCICD SEA Scoping Sessions

    DHI

    A scoping matrix was developed in relation to assessment Phases Locations (incl. distinction between marine and terrestrial) Receptors Risk/issue definitions

    The nature of the issues/risk were recorded in relation to: the definition of a strategic issue or risk (i.e. wide-scale, cumulative, potential

    planning conflict) indicated positive (+) or negative (-) nature additional information such as, location or rational, and the need for further

    analysis
