Urban development history
Historical Riyadh was enclosed by walls. At its center was a town square and a market (souq), surrounded by residential quarters of mosques and adobe homes, each with an interior courtyard. Outside its walls were orchards of date trees, hence the name 'Riyadh' or 'gardens'. During the 1930s, there was an initial outward expansion because new administrative buildings were needed for the country and because the population was growing. According to Dr. Saleh Al Hathloul, former deputy minister of town planning, this era coincided with the period of sedentarization as nomads settled in and around towns and cities such as Riyadh.
When commercial oil production began, there was a rapid rise in the rate of urbanization and the city transitioned from traditional to newer houses and buildings. This included the railway station and the (now-defunct) first airport of Riyadh. Government departments were relocated from Jeddah to Riyadh and new ministry buildings were built. To accommodate the government employees who had moved in from Jeddah, the government developed the Malaz housing block. This block's layout was influenced by the layouts of Dammam and Khobar, which in turn were influenced by the Aramco-built Dhahran. Malaz, with its street grid and detached house type, was instrumental in shaping the master plans for Riyadh that followed, as per Dr. Saleh Al Hathloul.
The Department of Municipal Affairs (later Ministry of Municipalities and Housing) selected Doxiadis Associates (DA) in 1968 to prepare a masterplan for Riyadh. After preliminary studies, they submitted a plan that was approved in 1972. They proposed that Riyadh will expand in the north-south axis along a commercial spine with and most importantly, that it will be divided into neighborhoods of 2 × 2 km blocks, thus solidifying the grid pattern to be the defining feature of Riyadh's layout. It also maintains the style of housing that was prominent in Malaz, detached houses with setbacks, designed in what Dr. Saleh Al Hathloul identifies as an 'international Mediterranean' style i.e. crimson colors. However, DA's shortcomings lay in their inability to accurately predict the extent of Riyadh's future growth.
At the start of the 70s, Riyadh did not go much beyond what is today the Khurais road. But nearing the 80s, Riyadh's expansion had already reached the Northern Ring Road in the north and had made considerable progress in the eastern part of the city.
In 1974, the government founded the High Commission for the Development of Arriyadh (later Royal Commission for Riyadh City) which was headed by the then governor of Riyadh Province, King Salman Bin Abdulaziz, who oversaw Riyadh's development. With the economic growth and national development plans of the 70s, the national infrastructure consisting of electricity grids, telecommunications networks, water pipelines, and highways was laid down that made further urban growth possible. The old and new industrial cities of Riyadh were both founded in this period.
The city grew at a much faster rate than Doxiadis Associates had projected and very soon, their plan became obsolete. DA predicted that Riyadh's urban area would be 304 km2 in 30 years when it reached 400 km2 just four years after the plan was authorized. Therefore, SCET International was assigned to revise and update the original plan to reflect the drastic growth and offer adaptive measures, which were approved in 1982. While keeping the 2km x 2km block, they expanded it in all directions unlike DA's linear expansion. They also added the radial ring roads and altered the DA conception of how commercial and other zones should be distributed.
It was in the 1980s and 1990s that most of the buildings that define Riyadh's urban identity were constructed. Built in styles contemporary of that time, marble with a hint of desert beige, these included the King Khalid International Airport, King Fahd Sports City, Television tower, King Saud University new campus, the King Faisal Foundation, the Ministry of Interior, Ministry of Foreign Affairs, MOMRA, and Imam Mohammad Ibn Saud Islamic University. And the historical district was rebuilt with the National Museum, Qasr Al-Hokm District, and the Imam Turki bin Abdullah Grand Mosque. Numerous health facilities were founded as well. Other developments in this period included the opening of the first shopping centers and supermarkets.
Approaching the 2000s, Riyadh had expanded well beyond the Northern Ring Road in the north and had reached the Second Ring Road in the east.
The MEDSTAR (metropolitan development strategy for Arriyadh) was the strategy that directed urban development in this era. Since the SCET plan also turned out to underestimate the rate of growth, a continuous approach instead of a one-off plan was adopted. The MEDSTAR was not a long term plan but an ongoing strategy on managing urban growth and economic development in the city. It was initiated after comprehensive studies by the Arriyadh Development Authority (the high commission's research wing) on demographics, land use, transportation, security, environment, and traffic safety. In 2007, MEDSTAR won second place in the international award for liveable communities. One of the MEDSTAR strategies was balanced development by turning Riyadh into a polycentric city rather than having one single downtown. [Riyadh: The Metamorphosis of a City From Centerless to Polycentric Fernando Perez,] This has resulted in there being multiple hubs scattered around the city such Al-Olaya, King Abdullah Financial District, Sahafa, Granada, Business Gate, Digital City, and Hittin.
Riyadh's skyline arose along the King Fahd Road starting in the 2000s. Significant construction projects like the Riyadh metro and the Princess Noura University, the world's largest women's university, were undertaken. Most malls and hypermarkets opened in this era and became a feature of city life. The municipality added wide sidewalks to a number of streets which became popular spots for walking, and parks were built in many neighborhoods. Major roads were redesigned, such as the King Fahd road, King Abdullah Road, Abu Bakr Al Siddiq road, and Oruba road, transforming the look of the city. In addition, the Royal Commission rehabilitated the Wadi Hanifa wetlands.
At the onset of the 2020s, Riyadh's expansion had gone further ahead of the King Salman Road in the north and had reached the Janadriyah road in the east.
Vision 2030 has stated its objective for Saudi cities to reach the list of top 100 cities of the world in quality of life and the city is working towards this goal through new development investments. Every year, the number of tourists visiting Saudi Arabia and Riyadh increases. In the large empty area where the old airport once was, the world's largest urban park, King Salman Park, is being constructed, with leisure, residential, office, hospitality, and retail spaces. The historical city of Diriyah, now encompassed by Riyadh, has been restored and developed into a cultural and tourist destination. Many roads and streets, such as the Olaya street and the Imam Saud road, are being refurbished.
Fewer malls are opening and squares (or plazas) are taking over in popularity, the most popular having been the Riyadh Boulevard on the Prince Turki Al Awwal Road. A new downtown called 'New Murabba' at the intersection of the King Salman and King Khaled roads is planned.
New fully residential suburbs, unlike regular neighborhoods that have storefront-lined main streets, are under construction in the far north and far east of the city.
