A scheme of "urgent" works to help protect homes from coastal erosion is to start soon.
It comes as around 2,000 tonnes of rock arrives on sea barges in a coastal town today (Friday) and this weekend.
The work "to help reduce the continuing risk of erosion" at Pakefield in Lowestoft was scheduled to begin last month - however, it was delayed as the sea barges' journey from Cornwall was held up amid bad weather.
With the work due to last around six weeks, Coastal Partnership East (CPE) - the coastal management team for East Suffolk Council - contracted Balfour Beatty to carry out the urgent works on the beach in front of Arbor Lane.
The rock will be placed "at the base of the cliff, at the most vulnerable points" in front of the access road in Arbor Lane, as without it "further cliff erosion would increase the risk of the access road being unsafe for use".
This would then "impact upon homes that are landward" of this "important access road".
In October, a council spokesman said: "Should the access road be compromised, it could affect more than 25 properties and have the potential to deposit significant quantities of material from the road onto the beach, causing issues of public safety."
According to Marine Traffic website, the tug Venture towed the barge Mormaen - laden with the rock - into Lowestoft at about 2.30am on Friday morning after a journey from Falmouth.
A second vessel Severn Sea towed the barge BCDK 6464 into Lowestoft, arriving around 11.45am, from Penryn.
This week a council spokesman said: "The rock is en route and due to arrive this weekend.
"Depending on wave heights, the rock will be offloaded and work will begin to get things in place as soon as possible to protect the community."
And with "accelerated erosion" continuing the owners of four clifftop chalets seaward of Arbor Lane had been told that "demolition is advisable".
The first of the four cliff-edge properties - The Rosary - was demolished in February, while Pakefield Holiday Park has moved some static caravans and lost some concrete bases.
Now, with the rock being delivered by barge, it will be moved into place at the base of the cliff by machinery.
And of the "urgent works" in Pakefield, a CPE spokesman said: "There will be a partial closure of the beach to the general public at times during our works.
"Please be aware the work will involve heavy plant and machinery on the beach.
"While plant is offloaded at Claremont Pier there will be restricted access to the area for a short period of time."
