The project includes 109 new homes made up of:

• 28 one-bedroom homes (for 2 people)
• 6 two-bedroom homes (for 3 people)
• 53 two-bedroom homes (for 4 people)
• 22 three-bedroom homes

The development will include:

• open spaces
• shared community spaces
• car parking
• bicycle parking

The buildings will be from 2 to 4 storeys high.

Environmental checks

DLR has carried out the following screenings to determine if the development could adversely affect nearby areas or the environment:

• An Appropriate Assessment Screening
• An Environmental Impact Assessment Screening.

These screenings have been carried out as required by the:

• S.I. No. 476/2011 – Planning and Development (Amendment) Regulations 2011
• S.I. No. 296/2018 – European Union (Environmental Impact Assessment) Regulations 2018.

The results of the screenings show that the proposed development:

• is not likely to have significant adverse effects on the qualifying interests, special conservation interest or the conservation objectives of any designated European site, and therefore an Appropriate Assessment is not needed
• is not likely to have significant effects on the environment, and therefore an Environmental Impact Assessment is not needed.

Within 4 weeks of this notice, you can apply to An Coimisiún Pleanála to review whether the proposed development could have significant environmental effects.
