There are three urban areas in the former Cooma-Monaro local government area which have flood prone land, these are; Cooma, Michelago and Bredbo. The provisions in the Cooma-Monaro Local Environmental Plan 2013 and this Plan aim to protect human life and property. Only the flood prone land in Cooma has had a flood study undertaken.
The Cooma Floodplain Management Study 1994 provides the basis for Council’s assumptions about the extent of the following flood events:
1:20 Annual Exceedance Probability
1:100 Annual Exceedance Probability
Probable Maximum Flood
Residential accommodation of any type shall not be located in the 1:20 Annual Exceedance Probability area. Refer to the Cooma Floodplain Management Study 1994.
A flood study has not been undertaken for Bredbo, therefore the 1:100 year flood level has not been determined. However, anecdotal evidence indicates that the south-eastern area of the village zone is flood prone.
Where development is proposed below the 701 metre contour within in the RU5 and RE1 Zones, a flood assessment will be required to be submitted by the applicant at the time the development application is with the consent authority.
A flood study has not been undertaken for Michelago. However, the southern area of the village adjacent to Michelago Creek is considered flood prone.
Where development is proposed on the southern side of Ryrie Street within the RU5 and RE1 Zones a flood assessment will be required.
Areas which are considered to be flood prone will require a flood assessment and will be assessed on a case-by-case basis. Where the likely extent of the 1:100 Average Recurrent Interval flood event is known or ascertained, the provisions of this Clause will apply to a proposed development.
