South Dublin County Council N7 Newlands Cross Upgrade
Environmental Impact Statement
Arup Consulting Engineers
14.6.3 Poddle River
There will be no significant residual impact on the Poddle River arising from the upgrading of
the Newlands Cross Junction.
14.7 Conclusion
The proposed upgrading of the N7 Newlands Cross Junction will not alter the current drainage
patterns on the N7. While the N7 is situated between two sub-catchments of the Liffey River,
the majority of surface water on this stretch of the N7 drains to the surface water system
located in Ballymount Park which drains into the Camac River system. The Camac River is
one of the larger sub-catchments of the Liffey River. The upgrading of the N7 Newlands
Cross Junction will have little or no impact on the Ballymount Park surface water system and
subsequently the Camac River during construction and operational phases. A broad suite of
mitigation measures will ensure that the existing water quality and aquatic ecology will not be
adversely affected by the proposed upgrade.
