PLANNING COMMITTEE AGENDA - Hartlepool Borough Council

4.1
10.20 The site lies within an area at high risk of flooding from tidal sources. The
applicant has completed a Flood Risk assessment in support of the application which
concludes that the finished floor levels should be set no lower than 4.885m AOD and
advises that comprehensive flood warning and evacuation procedures will be agreed
with the Local Planning Authority. It is considered that any flood risk issues could
therefore be dealt with through appropriate conditions on site levels.
DRAINAGE
10.21 The existing system has failed on several occasions and consequently
sewage has flooded parts of the Marina. Concerns have therefore rightly been raised
in relation to the adequacy of the existing drainage system to accommodate the
additional flows from the site. The information provided by the applicant has been
examined by our Engineering Consultancy who have concluded that it appears that
the system is barely adequate to cope with existing flows. The Engineering
Consultancy have advised that they have serious reservations about the practical
adequacy of the foul system but would wish to reserve final judgement until a CCTV
survey is provided and examined. However the applicant has appealed on the
grounds of non determination and in light of this the matter cannot be further
progressed at this time. It is considered at this time however that the applicant has
failed to demonstrate a satisfactory means of disposal for sewage/effluent. In
determining the appeal the Inspector will need to take view on this matter.
SEA WALL & LOCK
10.22 Given the developments proximity to the sea wall and lock concerns have
been raised in relation to the effect of the development on the foundations of the sea
wall and in relation to access to these structures for maintenance.
10.23 In relation to the impact on the sea wall the applicant has submitted structural
calculations and these have been assessed by our Engineering Consultancy. They
have responded that they have no objections to the proposal on the grounds of its
potential impact on the sea wall subject to appropriate conditions requiring further
investigations.
10.24 In relation to the access to the sea wall lock the applicant has advised that a
5.5m wide clear zone will be accommodated to allow for access to the sea wall and
this is acceptable to our Engineering Consultancy. This requirement could be
conditioned.
10.25 In relation to access to the lock this is a matter for the operator of the Marina.
10.26 In determining the appeal clearly the Inspector will need to take view on
whether the proposal is acceptable in relation to these issues.
HARBOUR/ BOAT LIFT ACCESS
10.27 Concerns have been raised that the siting of the building will affect navigation
of the dock. In particular it will obstruct a leading light located on, and visibility from,
the Lock Masters Office. The applicant maintains that the building has been sited so
