Subdivision of Land

When subdivision applications are referred to Island Health the district Environmental Health Officer will assess the applications and provide comments back to the Approving Officer in regards to the land parcels suitability in supporting onsite sewage disposal using Subdivision Standards

Health Protection plays an important role in land development providing input on water and wastewater infrastructure.  However, we are also willing to offer recommendations from the broader “Healthy Built Environment” perspective to promote healthy community planning.
