I would love nothing more than to get a whole whack of people out of their ridiculous cars. I see morons drive to their fucking mail box FFS.
such waste has to be called out and ridiculed.
How many drips come out of the 'yota? If you park or drive on streets, those drop straight into the ocean via storm drains… trying to find it now, I read somewhere that the equivalent of the Exxon Valdez dribbles into the Pugot Sound from Seattle every other year… I can't imajin that Vancouver is any better…
I'm saying before you try to rid yourself of tanker traffic, rid yourself of the damage that's actually occurring.
The first flush from urban runoff can be extremely dirty. Storm water may become contaminated while running down the road or other impervious surface, or from lawn chemical run-off, before entering the drain.
Water running off these impervious surfaces tends to pick up gasoline, motor oil, heavy metals, trash and other pollutants from roadways and parking lots, as well as fertilizers and pesticides from lawns. Roads and parking lots are major sources of nickel, copper, zinc, cadmium, lead and polycyclic aromatic hydrocarbons (PAHs), which are created as combustion byproducts of gasoline and other fossil fuels. Roof runoff contributes high levels of synthetic organic compounds and zinc (from galvanized gutters). Fertilizer use on residential lawns, parks and golf courses is a significant source of nitrates and phosphorus.
Separation of undesired runoff can be done by installing devices within the storm sewer system. These devices are new to the market and can only be installed with new development or during major upgrades. They are referred to as oil-grit separators (OGS) or oil-sediment separators (OSS). They consist of a specialized manhole chamber, and use the water flow and/or gravity to separate oil and grit.
