Purpose

To address public health and
safety concerns as a result of ongoing coastal erosion of the historical
landfill site at Alton Grove to Cador Drive.

 

Since October 2022, our coastal
Partners team has been identifying long-term options for addressing coastal
flood and erosion risk along the stretch of the Portchester shoreline from Alton
Grove to Cador Drive, in collaboration with engineering consultants AECOM,
through the Fareham Quay and Alton Grove to Cador Drive Flood and Coastal
Erosion Risk Management Studies. 
Completion of these studies is expected in Summer 2025, by which point
significant funding would need to be secured for detailed design and
construction of any future scheme. This work is being monitored regularly by
the Executive Member for Planning and Development and the Climate Change Scrutiny
Panel.

 

The ongoing coastal erosion is
leading to historic landfill materials being exposed.  Until a permanent solution is in place, any
public risks presented by the site need to be managed and, where necessary,
mitigated.  The risks at this site have
been comprehensively assessed and mitigation, in terms of enhanced periodic
multi-disciplinary inspections, litter picking, dynamic remedial action and a
clear escalation process, is proposed.

Decision

RESOLVED that the Executive
agrees that:

 

(a)  the
proposals for an enhanced inspection and management regime at this site be
supported;

 

(b)  risk
assessments be undertaken for the historic landfill sites at Salterns and Harbour
View; and

 

(c)  the
potential to also contain the landfill waste and reduce any risks to the public
and the wider environment be considered carefully when the outline designs and preliminary
cost estimates for a future coastal management scheme are reported to the
Executive later in the year.
