Prestatyn, Rhyl and Rhuddlan suffered floods last Thursday with Ffordd Penrhywlfa, Prestatyn experiencing the worst for the second time in a year.
Residents living along the road were left to battle to save their homes from flood damage as water surrounded their houses after the teatime rain.
Emergency services spent several hours helping clear the water, which evoked memories of flood damage caused by similar torrential rain last July.
Cllr Gerry Frobisher, who was at the scene for three and half hours, said: "The water was rising all the time, ever so slowly, until it seeped into all the houses causing damage to every downstairs carpet. The Fire Service were terrific.
"The crews from three tenders pumped water away from the front and backs of the houses for almost four hours, and did prevent more serious damage."
Contractors Daniel also pumped pumped thousands of gallons of foul water into their tankers and removed this from the scene.
Elsewhere in Prestatyn, there were reports of flooding in gardens of homes in Winchester Drive and Harlech Crescent.
His wife, Cllr Sharon Frobisher, vice chair of the North Wales Fire and Rescue Authority, said: "My first impression was complete devastation. It reminded me of last year's flash flooding at the same location.
"I must commend the hard work the Fire Service, Daniel and the Police Officers did throughout the evening to help minimise the damage and further flooding."
She now intends to hold a meeting with residents and the relevant services to avoid a repeat of the flooding problems.
There were also reports of flooding problems in Rhuddlan and at Garford Road, and Eastville Avenue, Rhyl.
Cllr John Bellis, who has convened a meeting allowing residents to discuss drainage issues in Rhyl East with Denbighshire County Council and Welsh Water this Thursday at Tynewydd Community Centre at 5pm, said: "I was first made aware of the problem in Garford Road.
"The roads were flooded and the drains just weren't able to cope witht he amount of water.
"Next I was told about the problems in Eastville Avenue.
"From what the residents have told me whenever there is a downpour of this level they have the same problem.
"And because of the trouble they have had over a number of years I thought teh best way to move forward would be for residents to put their opinions to Denbighshire County Council and Welsh Water."
