      Road Traffic Noise

       

      i) The Applicant shall analyse the scope of the existing and proposed road alignment(s) to identify appropriate existing and new road sections for the purpose of traffic noise impact assessment. When an existing road section undergoes major modification which will directly result in 25% increase in lanes or substantial changes in alignment or characters (e.g. change to a high speed road) of the existing road, it shall be regarded as a new road for the purpose of this noise impact assessment.

       

      j) The Applicant shall calculate the expected road traffic noise using methods described in the U.K. Department of Transport's "Calculation of Road Traffic Noise" (1988).

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.

       

      k) 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.

       

       

       

      l) Quantitative assessment at the NSRs for the existing and proposed road alignment(s) shall be carried out and compared against the criteria set out in Table 1A of Annex 5 in the TM.

      n) Where any of the proposed roads under this development is considered as a Designated Project under Schedule 2 of the EIAO, sub-clauses (na) to (nc) below shall be applied for the protection of NSRs in the vicinity of the proposed development:

       

      (na) 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 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 elements that will be benefited by the provision of direct technical remedies should be provided.

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

       

      (nc) 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 following three criteria:

       

       

      nc1) 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));

       

      nc2) 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 commence; and

       

      nc3) the contribution to the increase in the predicted overall noise level from the new road must be at least 1.0 dB(A).

       

       

    3. 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.

 

(viii) Evaluation of Constraints on Planned Noise Sensitive Developments/Land Uses

 

a) 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 planned noise sensitive uses can accommodate the additional measures to meet relevant noise criteria.
