A total of 284 homes in Wainfleet are now safe for residents to return to after the town was flooded.
Lincolnshire Police released a map of properties which are safe at 2.7 metres above sea level.
That map and a list of streets detailing where residents can return is being distributed and will be available at Coronation Hall.
Residents in the remaining 248 properties below that mark are still being advised to not return at this stage.
A spokesperson for the force said: “While appreciating that the situation remains frustrating for many, the Environment Agency has advised that it is not safe at this stage.
“If you have been in regular contact and receiving support from the NHS or Social Services during the past week, you will be contacted very shortly about arrangements to go home.
“Please don’t attempt to return home before you have been contacted.”
Experts are now looking at a more permanent solution and steel sheet puling will be installed as soon as possible over the next few weeks.
Assistant Chief Constable Shaun West, chairman of the Lincolnshire Resilience Forum, said: “The community spirit and togetherness shown by local residents has been nothing short of incredible.
“The emergency services, our partners and volunteers continue to work around the clock to get people back in their homes as soon as it is safe to do so.”
