1. Divert sewer runoff into groundwater

   Before 1850 when the rain fell on Vancouver, it soaked into the ground, which then fed the over 50 streams which crisscrossed the land. This water which supported a multitude of life then ran to the Burrard Inlet, False Creek and the Fraser River.

   Today most of rainwater ends up on asphalt streets and the rooftops of buildings and this water runs into countless sewers which end up in the same surrounding water systems. As the water runs into the sewers, it picks up pollution from cars, residue from asphalt streets and tar roofs and many other small and large volumes of toxic substances that exist on our urban streets today.

   While we cannot bring back the original streams, we can work harder to divert storm runoff into green areas that can soak up and neutralize the pollution before it enters the water table below.

   For example, one such activity could be to create pocket marshes in parks where there is poor drainage. Parks were often built in marshy areas of streambeds in the first place (eg. Trout Lake, Douglas Park, China Creek Park). We can put back some pocket swamps to drain the water into the ground instead of doing a poor job of diverting the water into sewers to remove it from the area.

   In addition to the ones in place, the Draft Greenest City Action Plan recommends increasing the number of infiltration systems.

   This link explains the types of integrated drainage that the City of Vancouver uses: http://vancouver.ca/engsvcs/watersewers/sewers/enviro/protect.htm#drainage

2. Celebrate water! Rain water, river water, ocean water -- let's treat it like we love it!

   Some ideas for celebrating water might include...

   • Making beautiful rain-powered water sculptures as public art
   • "Daylighting" our lost creeks
   • Creating new "creeks" (swales) and ponds to manage our stormwater
   • Making sure our rivers and ponds and coastlines stay/get clean enough to swim in and fish in and play in again

   What are your ideas?

   Where possible, streams are being daylighted http://vancouver.ca/commsvcs/cityplans/stillcreek/index.htm, swales and infiltration bulges are being installed http://vancouver.ca/engsvcs/streets/design/green.htm, rainwater is incorporated into public art at the Marine Drive Skytrain Station

3. Expand the Yellow Fish Markers on Storm Drain Sewers Program

   Historically, industrial man has been accustomed to using our waterways as a dumping ground for unwanted waste. Sadly this has led to our ocean becoming a toxic soup for animals and plants. Agricultural fertilizer runoff cause algal blooms. Inefficient or excessive garbage has caused many massive garbage (mostly plastic) islands to appear in the oceans and has had an adverse impact on seabirds and sea mammals. Chemicals are dumped down sewers and fish are killed immediately. In Burnaby Byrne Creek has had too many such incidents in the past few years; so many in fact that an initiative called “Stream of Dreams” was launched to educate the residents about chemical pollutants in drains.

   Our Federal Department of Fisheries and Oceans has introduced a program where community groups can paint or glue a yellow fish marker on the storm drain on their street. The yellow fish indicates that the sewer water goes to an area where there are fish and other sealife and we should be vigilant about not dumping pollutants and garbage down the drains. These kits are available through the City of Vancouver. This program should be expanded so that every street in Vancouver has yellow fish on every drain and every resident knows that the yellow fish means no toxic substances in the drains, even if that means buying a green car-washing fluid.

   Not part of the draft Greenest City Action Plan but new storm drains are embossed with an image of a fish.

4. Biodiversity and Permeability Standards through the Zoning By-law

   Create a biodiversity and permeability performance standards for new development through the Zoning By-Law. A variation on this could be create market incentives for more biodiversity.

   Permeability is already included in the Zoning Bylaw. Biodiversity is not covered by the Zoning Bylaw.
