Norwood Green residents want Ealing Council to install protective measures on the green to stop travellers setting up camp.
More than 20 caravans have set up only days after a previous group had left the green in Southall , which currently has no protective barriers and is completely open on all three sides.
Osterley Lane, which is next to the green, has already been blocked off by large logs in an effort to stop travellers from setting up camp down the lane near to Osterley Park.
The council were in the process of going through the legal proceedings for removing the previous travellers , but this process has now had to be restarted as the current group are a completely new group.
Residents held a demonstration near Norwood Green on July 14 to show unity and strength in the community, and to also show their anger that travellers have moved onto the green again.
Now the Norwood Green Residents Association want Ealing Council to take action and install a protective barrier around the green so that incidents such as this won't happen again.
A statement from the Resident Association read: "Residents of Norwood Green were once again shocked and saddened at the arrival of some 20 caravans setting up camp on Norwood Green on Thursday morning.
"This comes less than a week after the eviction and subsequent departure of the previous encampment that had caused village day to be cancelled for the first time in 38 years.
"Ealing Council were well under way with the clean up on the Green although the children’s playground was yet to be cleansed and reopened to the public."
'Clean-up costs outweigh barrier cost'
It added: "Thursday evening saw over 50 residents stage a peaceful protest outside St Mary’s Church Hall on the Green, this was intended to show the unity and strength of the local community and also the disgust that this could happen again, so quickly.
"The protest was good natured and policed by the local neighbourhood police team.
"The focus of the residents association is now to lobby Ealing Council to provide a protective barrier around Norwood Green. Perhaps a wooden morticed post and rail fence or a concrete post and single rail solution similar to those used in central Ealing parks.
"The constant disruption and clean-up costs far outweigh the investment of fencing provision and the security that this would offer the community.
"There is a ward forum in St Marys Church next Wednesday the 20th of July at 7pm where members of the residents association and community will deliver letters of concern to local councillors.
"It is imperative that concerns are provided in letter or email format to ensure their acceptance by councillors."
