Learning about ‘glasphalt’, tsunami signs & Halloween safety

Dear Street Smarts, Q: Your article [Monday] described the glass look in paving. It actually isn't sand -- it is glass. [It's called glasphalt.] When recycling began in the late '60's, the State of California quickly realized that demand -- not supply -- was the main hurdle to make recycling work. They attempted to expand markets for all kinds of recyclables. Glass cullet, or crushed glass, was a major one and the state provided incentives to use it whenever possible. Insulation and paving were targeted. The State even required a minimum recycled content for both materials. So, what you see when the pavement sparkles is recycled glass mixed in with regular aggregate. The crush is such that it can never affect tires on bicycles or cars -- they found out that the hard way. Your reader should celebrate the sparkle -- it's recycling at work! Peter Heylin via email A: Love my knowledgeable Street Smarts readers! Thank you for the information, Peter.

Q: Why is there a tsunami evacuation sign on the corner of 7th Avenue with an arrow pointing down Eddy Lane? That is a dead end street. Wonder why the evacuation sign is there. Thank you. Jeanne Thompson, Santa Cruz A: "The tsunami evacuation sign on 7th Avenue at Eddy Lane directs people to Jose Avenue Park at the end of Eddy Lane, which is designated as the safe zone during a tsunami event," said Jack Sohriakoff, senior civil engineer with county public works. Trick or Treating safety tips Friday is Halloween and if your kids are heading out for some trick or treating fun, here are some tips from the Central Fire Protection District:
  • Never let children trick or treat alone. Always head out in groups;
  • Know where your kids are going and what time they will be home;
  • Make sure they always cross streets at corners or crosswalks;
  • Never enter the homes of strangers;
  • Do not accept rides from people they do not know;
  • Only approach houses that are well lit as a sign of welcome;
  • Carry a flashlight;
  • Use sidewalks wherever available;
  • Teach children to dial 911 in case of an emergency; and
  • Keep children away from loose or fenced animals.
Once home, parents should inspect all treats for safety and discard any that appear to have been tampered with. Note to drivers, slow down and keep your eyes peeled for goblins and ghouls in search of treats.
