Calculations of future road traffic noise shall be based on the peak hour traffic flow in respect of the maximum traffic projection within a 15 years period upon commencement of operation of the proposed roadworks. The Applicant shall calculate the traffic noise levels in respect of each road section and the overall noise levels from the combined road sections (both new and existing) at the NSRs.

   2. Presentation of Noise Levels

      The Applicant shall present the prevailing and future traffic noise levels in L10(1 hr) at the NSRs at various representative floor levels (in m P.D.) on tables and plans of suitable scale. Quantitative assessment at the NSRs for proposed road alignment(s) shall be carried out and compared against the criteria set out in Table 1A of Annex 5 in the Technical Memorandum. The potential noise impact of proposed road alignment(s) shall be quantified by estimating the total number of dwellings, classrooms and other noise sensitive elements that will be exposed to noise levels exceeding the criteria set in Table 1A of Annex 5 in the Technical Memorandum.

   3. Proposals for Noise Mitigation Measures

      After rounding of the predicted noise levels according to the U.K. Department of Transport's "Calculation of Road Traffic Noise" (1988), the Applicant shall propose direct technical remedies within the project limits in all situations where the predicted traffic noise level exceeds the criteria set in Table 1A of Annex 5 in the TM by 1 dB(A) or more. Specific reasons for not adopting certain direct technical remedies in the design to reduce the traffic noise to a level meeting the criteria in the TM or to maximize the protection for the NSRs as far as possible should be clearly quantified and laid down. The total number of dwellings, classrooms and other noise sensitive element that will be benefited by the provision of direct technical remedies should be provided.

      The total number of dwellings, classrooms and other noise sensitive elements that will still be exposed to noise above the criteria with the implementation of all recommended direct technical remedies shall be quantified.

      In case where a number of the NSRs cannot all be protected by the recommended direct technical remedies, the Applicant shall identify and estimate the total number of existing dwellings, classrooms and other noise sensitive elements which may qualify for indirect technical remedies under the ExCo directive "Equitable Redress for Persons Exposed to Increased Noise Resulting from the Use of New Roads", the associated costs and any implications for such implementation. For the purpose of determining the eligibility of the affected premises for indirect technical remedies, reference shall be made to the set of following three criteria:

      1. the predicted overall noise level from the new road together with other traffic noise in the vicinity must be above a specified noise level (e.g. 70 dB(A) for domestic premises and 65 dB(A) for education institutions, all in L10(1 hr));

      2. the predicted overall noise level is at least 1.0 dB(A) more than the prevailing traffic noise level, i.e. the total traffic noise level existing before the works to construct the road were commenced; and

      3. the contribution to the increase in the predicted overall noise level from the new road must be at least 1.0 dB(A).

7. Assessment of Side Effects and Constraints

   The Applicant shall identify, assess and propose means to minimize any side effects and to resolve any potential constraints due to the inclusion of any recommended direct technical remedies.

8. Evaluation of Constraints on Planned Noise Sensitive Developments/Land Uses

   For planned noise sensitive uses which will still be affected even with all practicable direct technical remedies in place, the Applicant shall propose, evaluate and confirm the practicality of additional measures within the planned noise sensitive uses and shall make recommendations on how these noise sensitive uses will be designed for the information of relevant parties.

   The Applicant shall take into account the agreed environmental requirements/ constraints identified by the study to assess the development potential of the concerned sites which shall be made known to the relevant parties.

1. Field scan of all the historical buildings and structures within the project area.

2. Conduct a photographic recording of each historical building or structure including the exterior (the elevations of all sides of the building premises, the roof, close up for the special archit4ctural details) and the interior (special architectural details), if possible, as well as the surroundings of each historical building or structure.

3. Interview with the local elders and other informants on the local historical, architectural, anthropological and other cultural information related to the historical buildings and structures.

Archaeological Survey

Appropriate methods of field evaluation should be applied to assess the archaeological potential of the project area :

1. Definition of areas of natural land undisturbed in the recent past.

2. Field scan of the natural land undisturbed in the recent past in detail with special attention paid to areas of exposed soil which were searched for artifacts.

3. Conduct systematic auger survey/shovel testing to establish the horizontal spread of cultural materials deposits.

4. Excavation of test pits to establish the vertical sequence of cultural materials. The hand digging of 1 x 1 m or 1.5 x 1.5 m test pits to determine the presence or absence of deeper archaeological deposits and their cultural history.

5. If the field evaluation identifies any additional sites of cultural heritage within the study area which are of potential historic or archaeological importance and not recorded by AMO, the office should be reported as soon as possible. The historic and archaeological value of the items will be further assessed by the AMO.

(III) The Report of Baseline Study

The study report should have concrete evidence to show that the process of the above desk-top and field survey has been satisfactorily completed. This should take the form of a detailed inventory of the sites of cultural heritage supported with full description of their cultural significance. The description should contain detailed geographical, historical, archaeological, architectural, anthropological, ethnographical and other cultural data supplemented with illustrations below and photographic records.

Historical Buildings and Structures

1. A map in 1:1000 scale showing the boundary of each historical building or structure.

2. Photographic records of each historical building or structure.

3. Detailed record of each historical building or structure including its construction year, previous and present usage, architectural characteristics, as well as legends, historic person, historic events, cultural activities related to the structure.

Archaeological Sites

1. A map showing the boundary of each archaeological site as supported and delineated by field walking, augering and test-pitting;

2. Drawing of stratigraphic section of test-pits excavated which shown the cultural sequence of a site.

3. A full bibliography and source of the information consulted should be provided to assist in the evaluation of the quality of the evidence. It is expected that the study and result is up to an internationally accepted academic and professional standard.
