Reservations

U.S. Reservations are lands acquired for use by the Federal Government after the original founding of the city. These were all acquired by the Federal Government through purchase, condemnation, dedication, or gift and almost all the U.S. Reservations in Washington are under the Jurisdiction of the National Park Service. Unlike Appropriations, U.S. Reservations are found throughout the city. The National Park Service also has information for every U.S. Reservation and Appropriation in addition to DOB Office of the Surveyor having some detailed information on transactional history. It should be noted that RPTA has converted some reservations to tax lots for land tracking purposes however the federal government still maintains ownership in many of these cases.美国联邦保留地（U.S. Reservations）指华盛顿市最初建城后，由联邦政府收归使用的土地。此类土地均通过购买、土地征收、划拨或捐赠的方式由联邦政府取得，华盛顿市内几乎所有的美国联邦保留地均由国家公园管理局（National Park Service）管辖。与政府划拨用地（Appropriations）不同，美国联邦保留地遍布全市全域。国家公园管理局掌握所有美国联邦保留地与政府划拨用地的相关信息；此外，DOB测量员办公室（DOB Office of the Surveyor）还留存有部分此类用地的交易历史详细资料。需特别说明的是，RPTA为开展土地追踪工作，已将部分保留地转换为税籍地块（tax lots），但在多数此类情形中，联邦政府仍保有上述土地的所有权。
