1 Introduction
1.1 Purpose of this Addendum
1.1.1 The HS2 Scope and Methodology Report (SMR)( Volume 5: Appendix CT-001-000/1)
was published in Autumn 2012 and set out the proposed scope and methodology for
the Environmental Impact Assessment (EIA) for Phase 1 (London-West Midlands) of
HS2.
1.1.2 This SMR Addendum outlines where the methodology presented within the SMR has
been amended or advanced as a result of:
 legislation or industry best practice guidance having changed;
 the methodology having undergone refinement as a result of its application
within the EIA; and
 further feedback on the outlined methodology having been received from
stakeholders including statutory bodies following the ongoing application of
that methodology.
1.1.3 This addendum generally focuses on updates and refinement to:
 the establishment of the baseline and definition of the survey;
 the scope of the assessment; and
 the assessment methodology.
1.1.4 There has been no material change to Part A of the SMR, including the report’s
Introduction, the high level methodology presented within the ‘EIA Methodology’
section, and the reporting of scheme alternatives considered. The scope and
methodology contained within this addendum is generally presented in the future
tense to emulate the SMR (which, being a consultation document in advance of the
EIA was provided in the future tense).
1.1.5 The detailed assessment methodology is collated and presented in one or more
Technical Notes for some of the topic areas under assessment. These are appended to
this addendum. Not all topics have required the preparation of technical notes.
1.1.6 The addendum is arranged by topic area in the same order as they are presented
within the SMR. It should be noted that for ease of cross reference, the section
numbering of the remainder of this addendum document reflects the numbering
utilised within the SMR document. Thus Sections 2 and 3 of this document are
unused. Each section commences with a list of amendments to the SMR for the
particular topic.
