A declining Industrial Town has proposed to improve water sustainability by reducing stormwater runoff through change of land use land cover (LULC), as shown in the Table below, to attract new residents.
LULC | Runoff Coefficient | Existing Area in hectare | Proposed Area in hectare |
Industrial | 0.7 | 1500 | 800 |
Residential | 0.5 | 1000 | 1200 |
Park and Playgrounds | 0.25 | 1200 | 1000 |
Forest | 0.15 | 300 | 1000 |
Considering a flat topography and zero additional runoff from the adjoining areas, the reduction in run-off generation for a 400 mm rainfall event in the industrial town for the proposed intervention, in cubic meters, is _____
\(\times 10^6\) (rounded off to two decimal places).
