Creeks and streams are an important part of our coastal environment. They carry rain and melted snow to the ocean, and provide important habitat for fish.
A maze of underground storm drains carry rain and melting snow as it runs off roofs, driveways, roads and other hard surfaces. Along the way, it picks up pet waste, oil, fertilizers, pesticides and other pollutants. These substances are harmful, and if they enter drains and catch basins, they end up in our waterways and eventually the ocean.
You may notice that many West Vancouver streets are lined with open, unpaved ditches. These ditches help slow water down as it drains off roads and adjacent properties, reducing creek flows and erosion. Open ditches also give pollutants a chance to settle out before reaching creeks and the ocean.
Many properties in West Vancouver border on streams and owners are required to obtain an Environmental Development permit before doing any work within 15 metres of the top of a stream.
