URBAN UNDERGROUND CONSTRUCTION SPACE PLANNING

Article 10. Provisions on urban underground construction space planning

1. Urban underground construction space planning constitutes a content of an urban plan. The contents of urban underground construction space planning in an urban plan comply with the law on urban planning.

2. For urban centers with approved urban plannings or in which underground works, need to be constructed but have not yet been identified in the approved plans, the formulation of general plannings or detailed plannings on underground construction space shall be considered and decided by provincial-level People's Committees.

3. General plannings on underground construction space shall be formulated for urban centers; detailed plannings on underground construction space shall be formulated for urban zones or for use as a basis for the formulation of investment projects on construct of underground works. The planning contents comply with the provisions of Articles 12 and 13 of this Decree.

4. The appraisal and approval of general plannings and detailed plannings on urban underground space shall comply with the law on urban planning.

Article 11. Requirements on urban underground construction space planning

Underground construction space planning must ensure rational, thrifty and efficient use of land and compatible and synchronous connections of underground works and between underground works and ground works; satisfy the requirements on protection of the environment and ground water sources and safety of underground works and underground sections of on-ground works.

Article 12. Contents of urban underground construction space planning

1. Analyzing and assessing the natural, geological and hydrological conditions of works; the current state of construction of urban on-ground and underground works.

2. Analyzing and assessing the general urban planning and the state of construction under the approved planning.

3. On the basis of urban space and technical infrastructure development orientations already identified in general urban plans:

a/ Forecasting urban underground space development and use demands;

b/ Zoning of functional underground space for the construction of underground works;

c/ Identifying areas where construction of underground works is restricted or banned;

d/ Identifying underground traffic systems, including route directions, locations and sizes of underground railway stations (if any); positions and sizes of automobile tunnels and areas projected for the construction of underground car parks;

e/ Identifying systems of technical tunnels and trenches, technical culverts and tanks on principal thoroughfares up to zone level;

f/ Identifying water supply or drainage pipelines of grades 1 and 2, power transmission lines of 22 kV or higher;

g/ Identifying areas for the construction of underground works and underground key technical infrastructure works;

h/Projected technical connections and spatial connections;

i/ Strategically evaluating the environment;

j/ Projected priority construction items and resources for implementation.

4. A planning file includes explanations and
relevant legal documents; maps of current
underground work systems and the urban underground construction space general planning.

Article 13. Contents of detailed underground construction space planning

1. Analyzing and assessing the natural, geological and hydrological conditions of works: the current state of construction of on-ground and underground works; the provisions of the general planning and zoning planning related to the planned zone.

2. Determining the scope, boundaries, nature and use functions of space for the construction of underground works.

3. Determining specific locations, sizes and land use scopes of underground construction works.

4. Determining detailed locations of technical connections and spatial connections of works.

5. Strategically assessing the environment.

6. A planning file includes explanations and relevant legal documents; maps of the current state, maps of detailed planning on underground construction space and drawings describing the cross-sections of used underground space, which show a detailed vertical arrangement of underground works.
