Regulatory agencies (OMAFRA, APEO, MMAH), require municipalities uphold OBC in construction and have a duty to protect infrastructure from municipal drainage impact. When significantly altering the water table near homes a Geotech engineer is consulted resulting in an engineering report.

If a municipality chooses to raise marsh levels after maintaining them at a lower level for 25 years should due diligence be applied?, While a city’s can have this focus, it must still fulfil its duty.

Based on guidelines, the city can measure to assess homes at peak water levels. If necessary, probable risk can be confirmed with Monitoring wells. 

When Multiple  homes are involved, suggesting to individual households, to engage the services of a soils or structural engineer is inapropriate, the city's involvement must be proactive. 

OBC guidelines are followed when homes are built, but depicted homes subsequently near or adjacent to persistent water are another matter.

When a habitat's not planned, and is rashly implemented after the fact, this is when issues are overlooked.  Beavers will persist, municipalities must take the time to properly assess.

When a municipality is required to make ethical decisions this is too often not a priority.
