Houston, the fourth most populous city in the U.S., is located on the Gulf Coast plain and the biggest one in Texas.
Founded in 1836 and incorporated as a city on June 5, 1837, it was named after General Sam Houston, who served as president of the Republic of Texas.
The city is connected to the Gulf of Mexico by the Houston Ship Channel, making it one of the busiest ports in the country and a major export hub.
Houston is known for its Texas Medical Center, the largest healthcare and research complex in the world, and NASA’s Johnson Space Center, home to the Mission Control Center.
With a 2024 population of 2,319,119, Houston anchors a larger metropolitan area known as Greater Houston, which had an estimated population of 6,802,000 according to Macrotrends.
The city also has a thriving arts scene, which includes the oldest African-American theater in the Southwest and a significant role in U.S. space exploration.

ToggleHouston’s Geography and Unique Features
Location and Size
Houston is located 165 miles east of Austin, 88 miles west of the Louisiana border, and 250 miles south of Dallas. It spans a total area of 637 square miles, including 600 square miles of land and 22 square miles of water.
The city lies mostly on the Gulf Coastal Plain, with its landscape shifting from Western Gulf coastal grasslands in the south to the subtropical forest known as the Big Thicket to the north.
Natural Terrain and Flooding Challenges
Built largely on former forests, marshes, and swamps, Houston’s flat terrain presents ongoing flooding risks, particularly as greenfield development continues.
Downtown Houston sits at about 50 feet above sea level, with the highest points reaching 150 feet.
Historically reliant on groundwater, the city shifted to surface water sources like Lake Houston, Lake Conroe, and Lake Livingston to address land subsidence.
Houston now has access to 1.2 billion gallons of surface water per day, supplemented by groundwater.
Bayous and Waterways
Four major bayous—Buffalo Bayou, White Oak Bayou, Brays Bayou, and Sims Bayou—flow through the city and connect to Houston’s extensive drainage system, designed to manage stormwater and mitigate flooding.
Buffalo Bayou runs through downtown and forms part of the Houston Ship Channel, continuing past Galveston into the Gulf of Mexico.
These bayous are crucial for flood control and connect the city to the Gulf.
Geology and Faults
Houston’s geology is shaped by deep layers of clays, sands, and marine deposits from ancient river flows.
These layers have gradually compacted over time, creating rich oil and gas deposits.
Houston’s underlying salt domes are responsible for its oil and gas resources, as these formations trap hydrocarbons that have seeped up through the porous rock layers.
Over 150 active faults span 310 miles within the Houston area, though most move gradually without significant earthquake activity.
City Layout and Development Patterns
Houston’s original six wards evolved into 11 City Council districts, with development classified by areas inside or outside the 610 Loop.
Inside this “Inner Loop” are downtown, historic neighborhoods, and high-density developments, while suburban business hubs like Uptown, Westchase, and the Energy Corridor lie beyond it.
Houston lacks formal zoning laws but regulates development through lot size requirements and parking rules, allowing both density and suburban growth.
Land Use and Urban Sprawl
Houston’s absence of strict zoning regulations has led to a mix of urban and suburban growth, making it unique among major U.S. cities.
In 1998, the city reduced minimum lot sizes, sparking a surge in residential construction.
This approach has supported affordable housing, protecting the city from severe impacts during the 2008 real estate crisis, with a record $30 billion in home sales in 2019.
Climate and Weather Patterns
Houston experiences a humid subtropical climate with hot, humid summers and mild winters.
Summers bring temperatures above 90°F for over 100 days a year, while winter lows occasionally dip below freezing.
The Gulf of Mexico and Galveston Bay contribute to high humidity and the occasional spring tornado.
Houston is no stranger to snowfall, although it remains rare, with memorable snow events in 2004, 2008, and 2017.
Flood Risks and Major Storm Events
Today in 2017, Hurricane Harvey makes landfall south of Houston, as a category 4 hurricane, producing catastrophic flooding totalling 51” and 36 deaths in Harris County. #houwx

Houston is prone to flooding due to its flat topography and clay-heavy soil, which prevents water from draining quickly.
The city has endured major floods from events like Hurricane Harvey in 2017 and Tropical Storm Imelda in 2019.
These floods highlighted the need for resilient building codes, leading to regulations that require homes to be built higher in flood-prone areas.
Air Quality Concerns
Air pollution, particularly ground-level ozone or smog, is a significant issue in Houston, exacerbated by the nearby industrial areas along the Houston Ship Channel.
Though the city frequently ranks high for peak pollution, constant winds from the Gulf help maintain lower average ozone levels than other major urban areas.
Development in Floodplains
New regulations following Hurricane Harvey encourage flood-resilient construction.
Developers must now build two feet above the 500-year floodplain to reduce flood risk.
In one notable case, a developer plans to build 900 homes on an old floodplain golf course, requiring innovative drainage solutions to comply with new guidelines and protect future residents from flooding.

Historical Background
Houston was founded in 1836 by two New York entrepreneurs who purchased land along Buffalo Bayou, naming the city after General Sam Houston.
Incorporated in 1837, Houston became a temporary capital of the Republic of Texas and later a key cotton export hub.
Following the Civil War, the bayou system expanded to accommodate more trade, and by 1901, nearby oil discoveries led to Houston’s rise as a petroleum center.
By the 1950s, the city’s economic focus shifted towards energy as large corporations relocated to the area.
Since the 1990s, Houston has diversified its economy, reducing its dependency on oil.
