- Meeting of Services Overview Committee, Wednesday, 31st January, 2018 6.30 pm (Item 26.)
To receive an update from the Environment Agency
Minutes:
The
Chairman welcomed Natalie Wren, Nick Elbourne, Lee
James and Darsha Gill from the Environment Agency
(EA) to the meeting.
The
Environment Agency provided an update to the Committee on the Chesham culvert. It
was reported that 40 metres of the worst sections of the culvert needing
immediate attention had been replaced in September 2014. During this time, the
EA anticipated that there could be a wider scheme for Chesham to address the
failing infrastructure and flood risk to Chesham town centre.
It was
noted that a public consultation on options for the culvert was undertaken in
June 2017 and that there was generally positive feedback from the public for a
scheme to take place. Following a shortlisting process, a diversion option (an
open channel diversion of the Vale Brook alongside St. Mary’s Way) was chosen
by the EA as the preferred option. The Committee were advised that, if this
option was taken forward, the majority of the flow of the river would come around
the proposed new culvert and open channel. Benefits of this option included the
fact that the option would address the public safety concern of potential
collapse of the culvert and flood risk, make new sections of the culvert more
accessible for maintenance, as well as provide a long term solution to flooding
and flood risk. It was hoped that the diversion option would also provide wider
environmental benefits to the area. The EA reported the difficulties in finding
a solution for Chesham due to the presence of fluvial, surface and ground water
in the culvert. It was noted that the EA had permissive powers to carry out
maintenance, improvements and/ or construction works to manage flood risk.
It was
reported that Chiltern District Council (CDC) officers preferred a diversion
option into Skottowes Pond, although this option had been discarded by the EA
due to obstacles relating to the landscape as well as the need to install and
continuously maintain a pump. Members were advised that pumps were avoided where
possible and there had been numerous examples of pumps failing across the
country. Further, a pump would not fit in with the sustainability aspirations
of the Chiltern & South Bucks Joint Local Plan.
Members
noted that consultants were due to carry out technical work on the culvert, but
at present work had been suspended until an option could be agreed upon by all
stakeholders. The Committee were presented with previous CCTV survey images
showing the poor state of certain sections of the culvert. It was anticipated
that the worst sections of the culvert would fail in approximately 10 years time but that this was subject to the severity and
frequency of weather events. The EA were anticipating undertaking a further
CCTV survey shortly to assess the current state of the culvert. The Committee
were informed that contributions would be required from stakeholders and
partners for the work to be undertaken. Further, that the EA would ask for a
contribution from the Regional Flood and Coastal Committee (RFCC).
Members
agreed that a ‘do nothing’ scenario was not an option.
Further, that the results of an up to date CCTV survey would be extremely
helpful for assessing the current state of the culvert. It was noted that the
installation of pumps had never been a preferred option for Members. Whilst
some Members of the Committee were in support of the diversion option chosen by
the EA, others felt that it would not be a suitable option as it could affect
the viability of Chesham. It was noted that, if this diversion option was
chosen, the number of car parking spaces in the Star Yard Car Park would be
reduced potentially having a negative impact on the businesses in Chesham. The
Committee agreed that regeneration of the area would need to be part of the
solution.
The
Director of Services welcomed the commitment to embark upon work with the EA to
reduce flood risk in Chesham. In response to a question as to whether the costs
of emergency repairs were charged to riparian owners, the EA advised that this
was the case. Further, the EA had been allocated some government funding to
support the carrying out of emergency repairs, however, it was unclear if a
similar provision would be allocated to flood risk management from 2021. With
regards to the next steps for the scheme, the Committee were in support of the
Council engaging with its advisors concerning the technical work, the findings
of which were to be reported to a future meeting of the Committee. Following
the discussion, the Committee
RESOLVED:
·
that the comments of the Services Overview Committee be forwarded to
the Cabinet.
Note 1: Councillor C Rouse left the
meeting at 19:11.
