Temporary structures lifted for construction activities on land, in intertidal zones, and in streams must be removed within one month of completion of the construction activity.

The Com River has a maximum flood capacity of 22,000 cubic feet per second (cusec) at the city boundary between Madura Voyar and its mouth. An expert review panel had suggested that the Water Resources Authority should be consulted on the design and construction of the new jetty.
