(1) In making provision for or with respect to flooding, a development control plan must provide a comprehensive flood analysis that (without limitation) addresses or includes the following—

(a) the impact of flooding on proposed development, including an estimation of the extent of flood prone land, high hazard areas and floodways, the implications of the full range of floods and the safety of people using or within the site,

(b) the impact of proposed development on flood behaviour on and off the site (including existing and planned development in the wider area),

(c) the flood hazard in the area (including hydraulic hazard, flood warning time, rate of rise of floodwater and duration of floods) and access and evacuation issues,

(d) viable strategies to manage any adverse impact of proposed development on flood behaviour.

(2) In relation to flooding, the development control plan should be consistent with the provisions of the Flood Risk Management Manual and any relevant local and regional policies.
