Article One, Section 8, of the United States Constitution established a "District... become the seat of the government of the United States..." The Residence Act of 1790 (as amended), established this district and gave to the President of the United States the authority to fix the location of the site somewhere along the Potomac River. President George Washington chose the current site of the city in 1791, and it was surveyed later that year. At the time, it was not foreseen that the city of Washington would be coterminous with the District of Columbia, and Washington set the northern boundary of the city roughly where Pennsylvania Avenue is today. Washington chose Pierre (Peter) Charles L'Enfant to plan the new city. Although unnamed at the time, Pennsylvania Avenue was designed in the L'Enfant plan as a critical thoroughfare for bringing existing roads into the heart of the new city. It was also designed to link the "president's palace" with the Capitol building planned for Jenkin's Hill (now Capitol Hill).
