Federation Villages Floodplain Risk Management Study and Plan
Table 30: Floodplain Risk Management Plan FLOODPLAIN RISK MANAGEMENT MEASURES Benefits Concerns An identified location will allow the community safe refuge Aspects such as maximum capacity, land tenure, during a flood event without the need to relocate. The trigger levels and structure requirements will need selected location can also store supplies. to be considered.
Option Evacuation Assembly and Shelter (Boree Creek - Morundah)
Description Engage with the local community regarding the formalisation of a shelter and further assess the feasibility.

Response Measure
Improvements to Driver Safety
Undertake an investigation using the outputs from the FRMS&P to identify locations for the installation of road flood signage.
The installation of appropriate road signage pointing to routes likely to be cut and alternate routes, reduces the risk to drivers during floods, reducing the number of incidences of motorists driving through floodwater. Could potentially reduce demand on SES with a reduced number of incidents.
RM-01
Response Measure
Update Local Flood Plans to include Flood Information
Update local flood plans and operational plans to include information on flood risk, drawing on modelling and information provided in this FRMS&P
RM-02
Response Measure
Community Flood Awareness
Establish and implement ongoing and collaborative education to improve flood awareness.
Detailed information will allow for better management and recovery of flood risk and will increase understanding of the different levels and types of risk present in the study area. Flood awareness significantly improves preparedness for and recovery from flood events, building a more flood resilient community.

FPLs are effective tools to limit property damage to new development and redevelopment. FPLs may pertain to minimum floor levels or flood proofing levels depending on the type of development. The FPA defines the area to which flood planning controls apply.

Ensure developments are designed, constructed and managed in such a way as to minimise flood risk to the structure and (if relevant) its occupants, in addition to minimising the impacts of flooding. • Limit risk to life by prohibiting development (both residential and commercial) in known floodways, and therefore limiting the number of occupants in hazardous areas that may be subject to flash flooding; • Limit risk to proposed development by only making land that is either flood free or subject to low flood hazard available for development and thereby reducing the potential financial burden following severe floods for future residents; • Ensure flood risk to the broader floodplain is not exacerbated (e.g. by prohibiting development in locations that would obstruct flowpaths and redistribute flows).
