The cost for implementing a program to cut back dangerous trees is expected to reach VND35 billion ($1.62 million).
Authorities will apply a height limit to Khaya and other tall, potentially dangerous trees on various roads in order to prevent damages during the rainy season. The number of trees to be pruned sits at 10,854, around half of which are Khaya. In the summer, the foliage of these plants will contribute to a new look for streets while the cutting of dry branches will help to ensure public safety.
The minimum price of pruning Khaya trees in urban districts is VND1.7 million ($78.73) for trees with a diameter of 15-40cm and the maximum price reaches over VND12.5 million ($578.88) for trees with a diameter over 120cm. The maximum cost for the cutting and disposal of dry branches are just over VND800,000 ($37.02) and VND1.2 million ($55.57) respectively.
The number of Khaya in Hanoi has stayed at around the same level for seven years according to city plans, at about 5,306 scattered around the city's many roads and parks.
In March, the Hanoi Provincial People's Committee issued a plan for the investment in and development of the city's network of trees. Part of the plan is to cut down and replace 6,700 trees around Hanoi's streets, which has attracted plenty of criticism from citizens. The city has also spent VND1.3 billion ($60,203) putting numbers as markers on trees.
