The 30-hectare land allocated for car depot of Mumbai Metro III corridor at Aarey Milk Colony needs to be elevated to prevent water logging during monsoon. The land allocated to the car depot is close to Mithi River, and therefore there is a chance of flooding in the area.

The land allocated for the construction of the car depot is uneven, and therefore contractors have to level up both the low line and higher areas, according to Indian Express. Apart from elevating the land, MMRC will also construct drains to allow overflowing water to pass on to Mithi River.

The 30-hectare land also has a hillock and MMRC is unsure of its height until date. In reference to the height of the hillock, SK Gupta, Director (Projects), Mumbai Metro Rail Corporation (MMRC) said to the website, "We have to elevate the land anyway to take it above the flood level. So we may not have to work too hard on the hillock. Only a small portion of the top will have to be cut down."
