Diver Laura James‘s video shows what came out of just one “outfall” off Alki when stormwater was running fast and furious. Your everyday choices can ensure that stormwater is less toxic – and you’ll know what choices to make and not make, if you can spare an hour Thursday night, with a bonus side effect: Sanislo Elementary, which is hosting the event, will win $1,000 from Sustainable West Seattle, which is presenting it, if at least 50 community members show up. (The money would go toward a native-plant-education project at Sanislo.) Ready to help? Be at Sanislo (1812 SW Myrtle) at 7 pm Thursday. You’re also invited to stay afterward for an 8 pm meeting described by organizers as intended “to discuss a ‘greenway’ proposal to filter street stormwater on 21st and provide sidewalks or safe routes to school.” Plus – you’ll be gifted with a free native plant – and there’s free pizza.
