Best Time to Visit
Saturday mornings are notoriously packed. Mid-week visits are dramatically faster.
Tuesday and Wednesday afternoons — you'll often drive straight through with no wait. Avoid Saturday mornings unless you enjoy sitting in your car with a mattress strapped to the roof.
Only have yard waste? Skip the main Convenience Center line entirely — use the Wood Waste Area entrance instead. It's almost always faster. Check the signage before you queue up.
Curbside Recycling Reference
For items that don't require a landfill trip, use your blue bin. Not everything with a recycling symbol belongs here!
Put These IN
- Cardboard (flattened)
- Paper & Mail
- Glass jars & bottles
- Plastic bottles (#1–#7)
- Aluminum & steel cans
Keep These OUT
- Plastic bags & film
- Styrofoam & takeout cups
- Shredded paper
- Greasy pizza boxes
- Cables & electronics
If a plastic crinkles when squeezed (like a water bottle), it's usually recyclable. If it stretches or feels like a film (grocery bag, bubble wrap), don't put it in the bin. Take film plastics to Giant or Safeway instead.
