Document 5: Palermo: Today both the Papireto river and the Kemonia are covered up by buildings. However, the shape of the former watercourses can still be recognised today, because the streets that were built on them follow their shapes. Today the only waterway not drained yet is the Oreto river that divides the downtown of the city from the western uptown and the industrial districts. In the basins there were, though, many seasonal torrents that helped formed swampy plains, reclaimed during history; a good example of which can be found in the borough of Mondello.
Document 6: Oklahoma City: Walking trails line Lake Hefner and Lake Overholser in the northwest part of the city and downtown at the canal and the Oklahoma River. The majority of the east shore area is taken up by parks and trails, including a new leashless dog park and the postwar-era Stars and Stripes Park.

Document 10: Mexico City: Originally much of the valley laid beneath the waters of Lake Texcoco, a system of interconnected salt and freshwater lakes. The Aztecs built dikes to separate the fresh water used to raise crops in chinampas and to prevent recurrent floods. These dikes were destroyed during the siege of Tenochtitlan, and during colonial times the Spanish regularly drained the lake to prevent floods. Only a small section of the original lake remains, located outside the Federal District, in the municipality of Atenco, State of Mexico.
Document 11: Oklahoma City: The city is roughly bisected by the North Canadian River (recently renamed the Oklahoma River inside city limits). The North Canadian once had sufficient flow to flood every year, wreaking destruction on surrounding areas, including the central business district and the original Oklahoma City Zoo. In the 1940s, a dam was built on the river to manage the flood control and reduced its level. In the 1990s, as part of the citywide revitalization project known as MAPS, the city built a series of low-water dams, returning water to the portion of the river flowing near downtown. The city has three large lakes: Lake Hefner and Lake Overholser, in the northwestern quarter of the city; and the largest, Lake Stanley Draper, in the sparsely populated far southeast portion of the city.
Document 12: Lake Texcoco: Tenochtitlan was founded on an islet in the western part of the lake in the year 1325. Around it, the Aztecs created a large artificial island using a system similar to the creation of chinampas. To overcome the problems of drinking water, the Aztecs built a system of dams to separate the salty waters of the lake from the rain water of the effluents. It also permitted them to control the level of the lake. The city also had an inner system of channels that helped to control the water.
Document 13: Oklahoma City: In 1993, the city passed a massive redevelopment package known as the Metropolitan Area Projects (MAPS), intended to rebuild the city's core with civic projects to establish more activities and life to downtown. The city added a new baseball park; central library; renovations to the civic center, convention center and fairgrounds; and a water canal in the Bricktown entertainment district. Water taxis transport passengers within the district, adding color and activity along the canal. MAPS has become one of the most successful public-private partnerships undertaken in the U.S., exceeding $3 billion in private investment as of 2010. As a result of MAPS, the population living in downtown housing has exponentially increased, together with demand for additional residential and retail amenities, such as grocery, services, and shops.
Document 14: Todd Burns: Burns attended Oral Roberts University in Tulsa, Oklahoma, earning first-team All-America honors before being drafted by the Oakland Athletics in the 7th round of the 1984 MLB amateur draft. He played for the A's from 1988 to 1991, and would also play for the Texas Rangers (1992–1993), and St. Louis Cardinals (1993). He was nicknamed "The Mad Hatter" because of his habit of frantically tugging at the bill of his cap and re-adjusting it prior to every pitch as well as "Third Degree" for his penchant of giving up runs near the end of his career.
Document 15: Dammam: Having been built from the ground up, the Dammam Area was designed from the outset on the principles of modern urban planning. Residential areas are separate from commercial sections, roads are broad and straight and buildings conform to a master plan. One of the main features of the development of the area is land reclamation. Vast stretches of the shallow Persian Gulf waters have been filled, with hotels and office buildings occupying what were once marshes. Water for household, urban and industrial use is provided by desalination plants that supply approximately seven million cubic feet of treated water to the area each day. The availability of water underpins the urban and industrial growth of the Dammam Area, and provisions have been made for expanding existing desalination facilities to meet future growth.
