Well, with the new land development practices, we're applying low impact development. Any time a road widens, say, they have to address water quality before the discharge goes into creeks. Any new development has to address water quality before it goes into the creeks. On our debris-flow creeks, we have defined sediment basins so that we can clean it, so it doesn't disturb other parts. We also have a robust erosion and sediment control bylaw that limits construction practices, and you have to do sediment control during your construction activities.
