Washington, DC was the first capital in the world to be chosen, designed and built strategically. It was established by President George Washington. Washington was given the power to choose a permanent capital under the terms of the Constitution (1787) and the Residence Act of 1790, which authorized him to choose an exact location for the country's new permanent capital, as well as to choose commissioners to plan and build it within ten years. Washington's planning process is considered an example of what historic preservationists have come to define today as urban planning. President Washington, along with several commissioners, carefully surveyed the land to identify particular locations for use and was mindful of selecting and designating residential, government, and public areas. and commercial areas. Pierre Charles L'Enfant, the principal designer and one of Washington's commissioners, developed a network of public spaces of great variety to be used for civic, social, and national venues, all connected by broad diagonal avenues. The commissioners also created regulations for where to place buildings, structures, objects, monuments, and streets to develop a functioning city that would provide a location for the new government structure and could grow and mature in the future. The first hurdle in the planning process was deciding where to geographically locate the capital. Washington had been inaugurated in New York City and Congress had met in Philadelphia, but there was a push to find a new home. This process took place soon after the American Civil War, and the newly formed Continental Congress had members from both the South and North advising on the location of the capital. ... means of paper ...... of government”. The relationship between Washington and L'Enfant broke down – why this happened – what happened A version of his plan was published in 1796 and is said to have been the best city plan prepared before the nineteenth century, however the plan was soon drastically changed without L'Enfant's intervention. Conclusion:- how his project influenced the plans that were developed and how it influenced DC today. "It is probably fortunate that as much of the original design remains intact, as can be seen in the city today, since printed transcriptions of L'Enfant's accounts, sometimes made without his consultation, were altered in an attempt to interpret his poor English.” “So today we have four sections, NW, NE, SW and SE, as well as the rectangular plan combined with the radiating plan, giving the city conditions of stability and outward growth. ”.
