5.6 Landscaping<br />

5.6.1 General<br />

T.P.D.M. V.2.5<br />

(Al/2002)<br />

5.6.1.1 Considerable benefit can be obtained in terms of the general appearance, and lessening the<br />

impact of a highway project scheme on the surrounding environment by the use of<br />

landscaping techniques. Planting, if properly designed, can reduce visual impacts such as<br />

visual intrusion, monotony and glare. It can also help to break down noxious gas emitted<br />

from vehicles. In addition, landscape earth bunds can serve as noise mitigation measure.<br />

Furthermore, landscape planting can be used to create a green environment for pedestrians<br />

by creating visual interest, reducing temperature of roads by providing shade and absorbing<br />

radiation from the sun, enhancing humidity of the air etc. The planning and design of<br />

pedestrianisation scheme are covered in TPDM Volume 6 Chapter 10.<br />

5.6.1.2 Early inclusion of landscaping requirement both in the feasibility study of a road project and<br />

at the planning/design stage is necessary if the full benefits of suitable landscaping are to be<br />

obtained. Landscape works which may include tree planting should be designed as an<br />

integral part of the transport corridor. Any additional land provision for landscaping may be<br />

identified and allowed for. The planting area shall be free of disturbance from underground<br />

utilities. Furthermore, tree preservation should be thoroughly considered at the<br />

planning/design stage of the works.<br />

5.6.1.3 Consultation with the relevant body should also be carried out in respect of any landscaping<br />

adjacent to overhead cables of tram, or vehicles of the Mass Transit Railway Corporation<br />

Limited or Kowloon Canton Railway Corporation.
