Fireworks 2015: Cities Added!

July 4th is just around the corner and that means Fireworks!  Once again I bring you the fireworks app.  You can view cities in LA, Orange, and Ventura County that allow the sale and use of fireworks.  Included are days and times when fireworks will be sold and when you can light them up, as well as links to city web sites and telephone numbers.  Data was collected from municipal codes, web sites, and/or contacting each city.

This year the City of Anaheim and the City of Huntington Beach have been added to the map.  Through measures last year, voters decided to allow fireworks to be sold and used within their borders.  Congratulations to them and enjoy the app!

Built:LA

Inspired by previous building-ages maps that began popping up last year, urban designer Omar Ureta has created an interactive map of building ages in LA County.  Ureta used the building outline data from LA County’s GIS data portal.  You can click on the timeline to explore how the city has grown over time.  You can also hover over a building to reveal the address and time it was built.

Map of the Proposed Sewer System for the City of LA

Back in 1887, Fred Eaton, the City Surveyor, drew up plans for a proposed sewer system for the City of Los Angeles.  He estimated a cost of $1,000,000 to construct the proposed system.  A report from consulting engineer Rudolph Hering supported Eaton’s work and suggested spreading fields for the system.

I like how everything flows to one location, “Outfall Sewer”, at the lower left corner of the map.  I wonder if some of that infrastructure is still there today?  Check it out on the Huntington Digital Library site.

Map of California Roads For Cyclers

If you were a bicycling enthusiast back in 1896, you probably had this map on hand as you toured California.  The map was surrounded by advertisements to make sure you had the latest bicycling gear.  But more importantly the map outlined bike paths in red with labels which represented the road condition from good to very poor and the grade of the road from level to mountainous.

Check the map out on the Library of Congress site and download the high resolution image to see all the glorious detail!
