 Formulation of a consistent flood management strategy
in Indonesia started in 2002 with the establishment of theFlood Control Co-ordination Committee, (Bappenas
Decree 286A/M/PPN/07/2002)
 Resource persons from the relevant ministries underchairmanship of Bappenas.
 Following the approval of the new Water Resources Law(No. 7/2004), the three working groups of the committee:
 Spatial Planning; Technical Solutions and Financing and;
 Emergency Management

 Intensified their work and provided the basis for flood
management for Indonesia by the National Flood Control
Policy Plan3

Community Participation &Public CampaignThe objective of the community participation component was to formulate a number of activities
targeted at reducing the damage caused by flooding.
This was done in co-operation with the local communities of Kelurahans Tomang and Petogogan.
These flood prone areas were selected because of their typical profile: very densely populated
poor neighborhoods mixed with middle class residential lay-outs.
In the poor areas, land ownership and tenure is full of contradictions and irregularities.
These poor sections were affected the most by the 2002 and 2007 floods with up to 2 and 3
meters of inundation in Tomang and Petogogan respectively.

Community Participation &Public Campaign
 URDI, a NGO specialized incommunity participation,
supported the project team in thefield.
 Contacts were made with Lurah,
Camat in both Kelurahans, andwith the Dinas PU-DKI.
 Community leaders and informalleaders (mostly older religious
leaders and concerned citizens)were invited to join the so-called
Community Working Committee(CWC).
 It was very encouraging that thepopulation of the areas welcomed
the idea of community
participation to reduce the risk offlooding.
