A protest opposing the plans for a multi-million pound business park at Sidford will be held next month.
Campaigners have also launched a petition and have called on residents to join forces and back their efforts.
So far, more than 200 objections have been lodged against the application to create 8,445sqm of employment floor space on the Two Bridges site.
The plans, which could create 250 jobs, represents 37 per cent of what was previously proposed and submitted to East Devon District Council (EDDC) in 2016.
When the Herald went to press, a total of 232 comments had been submitted to EDDC – this included 211 objections and 20 supporters.
From Monday, July 9, Say No to Sidford Business Park campaigners have said they will be going door-to-door in Sidford and Sidbury in order to obtain signatures for their petition, in the first instance.
Volunteers then plan to submit the signatures to EDDC before the authority’s Development Management Committee makes a decision on the application.
Anyone who would be interested in volunteering on one or more of the days between July 9 and 12, from 6pm until 8pm, has been asked to come forward to help collect signatures.
Campaigners will also have street stalls in the centre of Sidmouth on Saturday, July 14 and Saturday, July 21.
Volunteers will be collecting signatures for the petition and will be seeking help from anyone who would like to help with the Say No to Sidford Business Park drive.
A campaign spokesperson said they would be running a number of initiatives throughout July.
A protest will be held on Monday, July 23, between 4pm and 5.30pm. Further details will be released closer to the time.
A spokesperson said: “We would like to thank everyone who has so far put a ‘NO Sidford Business Park’ poster in their window.
“This is an easy way of showing your opposition to the planning application.
“Please print and display the poster and give copies to friends and neighbours to put up.
“If you know of someone who you want to receive our emails then let us have their email address and we will add it to the extensive contact list.
“Thank you for the many messages of support that we have received.”
