Dear Rawiri
Request made under the Official Information Act 1982
Thank you for your email
of 11 December 2019 requesting the following information under the Official
Information Act 1982 (the Act):
Please provide technical/engineering material related to the management of stormwater as
designed for: (1) The new SH2/SH58 Haywards interchange, and (2) The current SH58
safety improvement works.
Specifically, I am interested in the placement and sizing of drains, pipes and where they
discharge, and/or where they may connect into local stormwater infrastructure.
The documents that fall within the scope of your request are set out in the document schedule on the
following page and are attached to this response as
Appendices A to
J. Please note that there may
be some refinement to the attached SH58 safety improvements plans due to unforeseen site
conditions.
Certain information has been withheld under section 9(2)(a) of the Act in order to protect the privacy of
natural persons
. With respect to the information that has been withheld, I do not consider there are
any other factors which would render it desirable, in the public interest, to make the information
available.
