Amendment C217ball - Ballarat 11 Waterways Flood Overlay Update
Current Production Status
C217ball current status: exhibited 29 April to 29 May 2026; directions and panel dates are listed for August 2026; final panel report, adoption, approval, gazette and GIS layers are not in corpus.
Amendment C217ball is the statutory implementation pathway for Ballarat’s 11 Waterways Flood Study. It proposes new FO2, LSIO2 and SBO1 controls over 4,260 affected properties, translating updated 1% AEP flood modelling with 2100 RCP8.5 climate-change assumptions into planning permit, referral, floor-level, safe-access and flood-storage requirements.

Current Status
As at 31 May 2026, C217ball had moved beyond “authorisation sought”. Public exhibition ran from 29 April 2026 to 29 May 2026, the next listed directions hearing is 3 August 2026, and the listed panel hearing is 31 August 2026. (Source: web-research-L1-flood-amendment-c217ball-council-news.txt; Source: web-research-L1-flood-amendment-c217ball-explanatory-report.txt) The correct status is therefore exhibited/post-exhibition, not pre-authorisation. Any earlier statement that the amendment had only reached authorisation stage is stale.
Statutory Mechanism
The amendment inserts Schedule 2 to the Floodway Overlay, Schedule 2 to the Land Subject to Inundation Overlay and Schedule 1 to the Special Building Overlay. (Source: web-research-L1-flood-amendment-c217ball-explanatory-report.txt) FO2 targets waterways, main flood paths and high-hazard areas; LSIO2 targets flood storage, flood fringe and lower-hazard inundation; SBO1 targets urban stormwater flooding where drainage capacity is exceeded.

Affected Scope
The explanatory report identifies 4,260 affected properties: 1,747 within FO2, 2,676 within LSIO2 and 1,078 within SBO1, noting overlap where a property is affected by more than one overlay. (Source: web-research-L1-flood-amendment-c217ball-explanatory-report.txt) Affected locations include Ballarat Central, Bakery Hill, Soldiers Hill, Alfredton, Lucas, Winter Valley, Sebastopol, Delacombe, Warrenheip, Bonshaw, Smythes Creek and Cambrian Hill.

Relationship To C243ball And Bridge Mall
C217ball materially affects the Bridge Mall/Bakery Hill built-form pathway because C243ball Part 2 depends on updated flood mapping before final DDO controls can be settled. (Source: web-research-L1-flood-amendment-c217ball-explanatory-report.txt; Source: 14-august-2024-planning-delegated-committee-meeting-agenda-with-attachments.pdf) The practical dependency is that DDO height, built form, access and basement or ground-floor design should not be finalised in flood-affected precincts until the C217 flood-control geography and schedule requirements are known.
Source Limits
The corpus includes the summary flood study, amendment explanatory report and draft schedules, but not the post-exhibition submissions, panel report, adopted amendment, approved maps, GIS layers or property-specific flood reports. (Source: web-research-L1-flood-amendment-c217ball-explanatory-report.txt; Source: ballarat-11-waterways-flood-modelling-summary-report.pdf, p.51) This page can state the exhibited amendment scope and mechanism, but not the final post-panel control boundary or submitter-specific changes.
