HS2 Phase 2a West Midlands - Crewe
Environmental Impact Assessment Scope and Methodology Report Addendum – Part 1

1 Introduction
1.1 Purpose of this Addendum
The HS2 Phase 2a Scope and Methodology Report (SMR)1 was published in
September 2016 and set out the proposed scope and methodology for the
Environmental Impact Assessment (EIA) for Phase 2a (West Midlands - Crewe) of High
Speed 2 (HS2).
This SMR Addendum outlines where the methodology presented within the SMR has
been amended or developed as a result of:
• legislation or industry best practice guidance having changed;
• the methodology having undergone refinement in the course of preparation of
the Environmental Statement (ES); and
• further feedback on the outlined methodology having been received from
stakeholders including statutory bodies following the ongoing application of
that methodology.
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.
The scope and methodology is generally described to reflect the approach in the SMR
(which, being a consultation document in advance of the preparation of the ES also
used the future tense).
This addendum sets out minor changes to Part A and Part C of the SMR, in Sections 2
to 5. It should be noted that for ease of cross reference, the section numbers and title
headings used in this addendum match those used in the SMR. For that reason, where
there is no change made the section is marked as ‘not used’. Where paragraphs/tables
etc. from the SMR published in September 2016 have been amended, the original
paragraph/table subject which has been subject to change is identified as follows -
[bold italicised].
Part B of this addendum is arranged by topic in the same order as they are presented
within the SMR. The section numbers in Part B match those used in the SMR. Thus,
sections of this document where no change has been made are marked as ‘not used’.
Each section commences with a list of amendments to the SMR for the particular
topic.

Phase 2b will be sought through a separate hybrid Bill that is expected to be laid
before Parliament in 2019. Construction of Phase 2b is anticipated to commence in
