REPORT:

The River Camac FAS is currently in Stage 1 - Scheme Development and Preliminary Design which consists of assessing options for, and then fully developing, a viable, cost-effective and sustainable scheme to the Target Standard of Protection of a 1 in 100 year rainfall event.

Focus is currently being placed on data gathering and on the overall impact from flooding along the whole catchment. Focus will be placed on more defined specfic areas when the hydraulic assessment has been completed and project optioneering commences. Optioneering is currently scheduled to commence in Q2 2021. 

To assist in the project optioneering, numerous studies and surveys along the catchment are required and a number have been completed to date, all in accordance with the relevant government guidelines and restrictions in respect of Covid-19, these included;

• Topographical Survey - Completed in December 2020
• Bed Level Surveys of Brittas Ponds and Corkagh Park Lakes - Completed in November 2020
• Seasonal Environmental and Ecological Data Surveys which included for Flora and Fauna; Birds; Mammals; Aquatic Life and Bats - Completed in November 2020
• Hydrology Study - Initial draft issued in December 2020

Studies and surveys currently taking place include for;

• CCTV Surveys of selected culverts
• River Restoration and Hydromorphology Assessments
• Wintering Birds Survey
• Hydraulic Modelling Works 

Stage 1 is currently estimated to be completed in Q1 2022 but this date may be impacted due to Covid-19.

In relation to current project communications, up to date information on the scheme can be found at www.camacfas.ie. It is also an intention of the project team to host an open on-line update event in Q1 2021. When the date has been confirmed, notifications will be sent to all relevant stakeholders.
