looding in Pantai Mutiara on the north coast of Jakarta on Friday has demonstrated the importance of building a seawall to enclose Jakarta Bay, the National Development Planning Ministry has said.
Jakarta Development Planning Board head Tuty Kusumawati said on Monday the construction of the seawall, which would be part of the National Capital Integrated Coastal Development (NCICD) program in North Jakarta, was crucial.
“It is urgent that the seawall be built, otherwise Jakarta will drown," Tuty said at City Hall.
She said the groundbreaking for phase A of the seawall would be held soon, adding that Jakarta was subsiding at an alarming rate.
"The level varies from 1 to 2 meters under the sea,” Tuty asserted.
Phase A of the seawall will be constructed in Pluit, North Jakarta, she said.
The existing height of the seawall is 3.7 meters, which will be extended by 1.1 meters, Tuti said.
"So the total height will be 4.8 meters and the length about 95 kilometers," she said.
The central government is conducting the project through Ciliwung-Cisadane Flood Control Office (BBWSCC), state-owned enterprises, regional-owned enterprises and private companies, Tuti said.
Currently, the Jakarta Environmental Management Agency (BPLHD) and the BBWSCC are reviewing and improving the environmental impact analysis (Amdal) on the construction in Pluit, she said.
Tuty added that the city would spend Rp 377 billion to build the dike along three rivers, namely the Kamal, Kaliadem and Blencong rivers.
The assistant to the governor for spatial planning and the environment, Oswar Muadzin Mungkasa, added that phase A of the seawall would not function optimally if groundwater usage was not limited.
“The construction of phase A will not be optimal if the ground keeps subsiding due to the uncontrolled usage of groundwater,” Oswar said.
The administration will also build green buildings, starting with the construction of the Daan Mogot low-cost apartments, he said.
The administration will also ensure that buildings construct water injection wells to mitigate flooding, Oswar said.
The groundbreaking ceremony for the mega-project was held in October 2014. The Netherlands and Indonesia have joined hands in the project. (dan)
