Naming a street involves multiple parties starting with real estate and subdivision developers who submit the city’s name for review. The views of local engineering and public work departments are then taken into consideration. They often have the power to veto the name to avoid any possible conflicts or confusion. Many cities have well-laid out street naming conventions and guidelines that must be followed. Proposed street names that deviate from such policies stand a high chance of being rejected. For instance, where trees are used in street names in certain parts of Philadelphia, Washington D.C., street names aim at representing all 50 states.
