My concerns relate to the Appleby Creek tributary.

There are 4 basic issues:-
1. Reach ACT-01 is predicted to have frequent erosive events and flooding of the channel under both existing and proposed conditions. [ref: Appleby Creek and Tributary Fluvial Geomorphological Assessment- Millcroft Green Phase 2 ,GEO Morphix Project No. PN25037, Feb 3, 2026, p.17-18]

2. With the start of site preparation which includes tree removal and topsoil removal including ground cover (surficial soil), there will be a significant loss of capability to absorb rain water. The reduction of absorption is at least 57%; the lack of water absorption will direct more water flows through the Appleby Creek tributary; it is important that with the development of each area H, I & J, the Storm Water Management plan is implemented before major road and residential construction is started. {Ref: Table 4: Post-development Infiltration Volumes, Millcroft Hydrogeological Assessment and Water Balance – Phase 2 City of Burlington R.J. Burns & Associates Limited, December 2025, 300043939.0001, p.15}

3. There is great reliance on average values for much of the interpretation of post-development expectations. As an example the average precipitation is shown as 902 mm/year; and the average rain event is 25 mm/day. While both of these number may be correct mathematically, the fact is a major concern must be the extreme events such as the storm event of August 4th 2014 when the rainfall was listed as 191 mm.

4. It is not clear what the process would be to validate that the water balance projections are correct and how that would be validated post development. If there are deficiencies, who would be responsible for remediation? Would the residents of Burlington become responsible for deficiencies?
