To build the city, developers are using dredgers to gather up sand from the bottom of the ocean.
CHEC ultimately plans to add 65 million cubic meters (around 17 billion gallons) of sand along the shore.
Environmental groups have raised concerns about the destruction of aquatic life, which could damage the livelihood of local fishermen. But developers contend that dredging won't pose a threat.
CHEC recently obtained a permit that allows it to dredge 5 kilometers from the coastline and only at depths at or below 15 meters. The organization is also prohibited from dredging in areas near reef habitats or fishing grounds.
To account for the economic cost to local fishermen, the company has set aside nearly $7 million to be distributed among fishing associations over the course of three years.
Developers have completed more than 90% of their reclamation efforts, putting them on track to finish by June 2019.
The project has received a $1.4 billion investment, but the sand itself could cost more than double that amount.
Colombo's Centre for Environmental Justice estimates that the development will require around 100 million cubic meters of sand, worth around $3.2 billion.
A "central park" borders the main canal, providing space for outdoor recreation and events.
The entire development features 110 acres of public parks and 300 acres for recreation and water sports.
Building heights decrease in the direction of prevailing winds and waterfronts, allowing for increased air circulation within the city.
The city is designed specifically for residential and commercial use — no industrial activities are allowed.
According to development officials, other planned projects in Sri Lanka will satisfy the need for industrial space.
