Many of the major cities in Florida use numbered street and avenues. Miami for one, and where I grew up, St. Petersburg is another. If used properly it's a great way to find a location quick. I grew up at 670 17th Ave. South in St. Pete. That is 17 blocks south of Central Ave and 7 blocks west of Tampa Bay.
Central Avenue runs east to west and divides St. Petersburg into north and south. So if you lived at 17 ave. North, and I live at 17th Ave. South, you would be 34 blocks north of me. Avenues run east and west, streets run north and south and start at Tampa Bay. If you are on 4th Street North, you are 4 blocks west of Tampa Bay and somewhere north of Central Avenue. The easiest place in the world to find an address without looking at a map is St. Petersburg.
There are exceptions, a few streets have names, however they are in alphabetical order. Because Tampa Bay isn't at 90 degrees and slants to the northeast. Streets east of 1st Street are labeled as Northeast. So 2nd St. Northeast would be north of Central and east of 1st St., there is only about 3 or 4 streets that are northeast.
