For the first time boardwalks will be constructed to
allow Otago Harbour's heritage sea wall to be seen as part of
the proposal to ''fill in the gaps'' between the cycle and
walkways along Otago Peninsula roads from Dunedin to Harington
The Dunedin City Council is applying for 10 coastal resource
consents from the Otago Regional Council and four land-use
consents from itself to widen the road between Vauxhall and
Harington Point to improve traffic safety at a cost of about
The consent proposed the work be done in seven stages during
the next 25 years and once completed would create a
continuous cycleway and footpath from Dunedin to Harington
However, the work programme was flexible and depended upon
community priorities and funding arrangements, the resource
consent application said. It would be discussed by the city
council in its upcoming annual plan deliberations.
To complete the widening, 13.4km of harbour sea wall, a
listed heritage structure, would be ''entombed'' except for
four lengths of between 80m and 225m considered to be of high
heritage importance by the New Zealand Historic Places Trust,
the application said.
Those stretches would only be covered by a boardwalk for use
by cyclists and pedestrians.
The widening also meant several boatsheds would need to be
relocated further into the harbour, while others would need
their access reconfigured.
''It is stressed that any relocation will be no more than is
required to accommodate a widened road.''
The widening would also allow for bays to be formed so buses
could pull off the road and for the Portobello Boat Club to
be relocated to solid foundations instead of piles.
The road could be raised in those areas to decrease surface
flooding and it is proposed to use large rocks where there is
significant boating activity, such as Portobello jetty, to
minimise wave reflection.
Ecological assessments done for the previous widening work
completed in 2011 indicated the road improvements appeared to
have very little effect on the ecology of the intertidal
environment along the stretch of Otago Harbour coastline, the
''Any effects observed in the two post-construction surveys
have been minor or transitory, with a slight improvement in
diversity and abundance of intertidal animals.''
However, the issue of cumulative effects of progressive
reclamations, as up to 20% of cobbled intertidal zone might
be lost following the completion of all the work proposed,
needed to be ''seriously considered'', the report said.
''It is considered that on balance, any adverse effects,
particularly on heritage, are either mitigated or offset by
the positive aspects of these applications, these being road
Submission on the applications close on February 17 at 5pm.
