Residents affected by the BusConnects initiative said they feel the National Transport Authority (NTA) does not understand locals' concerns, with plans instead being "pushed through regardless".
A public meeting was held yesterday in Terenure, South Dublin, and Fine Gael councillor Anne Feeney said some residents had been notified that sections of their gardens or frontage may be reduced to make way for the bus corridor.
However, some residents who have had one-to-one meetings with BusConnects representatives weren't happy.
"There's a feeling some of BusConnects are not as familiar with the area as they should be," Cllr Feeney said.
"There's a feeling that a process was being followed, but they weren't really being listened to or heard."
Although the NTA has advertised its plans online and in newspapers, Cllr Feeney felt a large number of people across Dublin still did not understand the impact the scheme could have, and said she was disappointed more road crossings had not been included in plans.
Businesswoman and Terenure resident Caroline Kennedy (47) is concerned the plan could affect her company's deliveries.
"I don't know how I'll get deliveries. You won't be able to drive into Terenure," said Caroline, who runs Indian Field design and print management on Rathfarnham Road.
The mother-of-three said parents should also be concerned that their children may have to get more than one bus to get to school if routes are changed.
Cathy Corcoran, of Lower Kimmage Road Residents' Association, said people in her area were "concerned about the environmental impact the bus corridor will have".
She said she felt motorists would be forced to drive into residential areas and that would create a "rat run", while cars would no longer be able to drive to Mount Argus Park or church.
"Buses will be travelling down the corridor non-stop. It's an excessive plan," she said.
"Householders who may be impacted have been sent letters. We've offered one-to-one meetings with our technical teams," an NTA spokeswoman said.
"The letters are not compulsory purchase orders, they are letters of information to say there may be impacts on the property if there is approval.
"We're establishing community forums and we ask people to email us if they are members of residents' associations.
"There will also be a general public information day in the coming days and information will be on our website.
"For phase two, 665 letters have been issued. These are information letters advising people that portions of their gardens/frontage may be impacted.
"We're at a public consultation stage - that will be followed by detailed design, then a full planning application, including an environmental impact assessment report, to An Bord Pleanala by the second quarter of next year."
