URBAN DEVELOPMENT PATTERNS: Bellaire, TX

In this post, I will discuss the patterns of urban growth and development in my hometown of Bellaire, TX.

Bellaire is unique to the Houston area primarily for one reason: as an independent city, Bellaire maintains its own very strict zoning ordinances and building regulations. Replats and zoning changes of any kind are extremely difficult to obtain from a constantly development-wary city government. For this reason, developers, builders, speculators and homeowners are chained to the single-family format originally planned over a century ago.

This policy has allowed the neighborhood character to remain relatively intact even as nearby areas become increasingly more densely built and heavily populated with commercial retail, townhomes, apartments and condominiums.

The First Boom: WWII Expansion

Bellaire was founded by William Wright Baldwin in 1908 after he purchased the 7,449 acre Rice Ranch, and was one of Houston's original "streetcar suburbs", originally serviced by a streetcar running from Houston, down Holcombe and Bellaire Blvd. to the town center, until it was abandoned in 1927.

Development in Bellaire was relatively slow, and it remained a sleepy, residential and agricultural town on the outskirts of Houston until the post-WWII building boom made it an attractive place for returning veterans to establish their families.

It is for this reason that most of the original housing stock is made up of humble, one-story ranch homes often on plots of land as small as 5000 square feet (50x100), built between (approximately) 1940 and 1965. The buildout more or less concluded Bellaire's first building boom, and development zoomed further west and south.

The Second Boom: Built By Oil

Facing decline following the 1970s, which proved a tough decade for the Houston area, the location - only a few miles from downtown and in the shadow of the Med Center and Galleria area employment hubs - and Bellaire's well-regarded schools, kept the area somewhat attractive. Development was once again reignited by the oil boom of the 80s as more and more residents were priced out of the "it" areas of the time - River Oaks, et. al. - and ventured outward to greener (and more moderately priced) pastures.


The area was well regarded for its schools, safety, and community atmosphere, but the "Not Quite River Oaks Money" crowd would not be satisfied by the humble nature of the existing housing stock. Instead, they began to tear down these existing homes - some of them barely 20 years old - and replace them with newer, much larger homes, but still constrained to the tight original lot sizes.

To preserve open space, protect trees, and ensure proper storm runoff, the city mandated that all new single-family new construction must be either 2 or 3 stories tall. The resulting housing stock from this second era of building (Ranging from the oil boom 80s until the 2006 financial crisis) consists mainly of either acutely banal (right) or excessively ornate (bottom) "McMansions" (often suspiciously identical to the bloated tract homes of suburban Houston) crowded onto a 5-7,000 square foot lot.

The second boom replaced approximately half of the original houses in Bellaire, and new constructions powered forward at a breakneck pace until the 2006 financial crisis.

Post-Recession Bellaire and where we go from here

Growing up in Bellaire, it was amazing to me to see the various historical eras represented around me by houses. Perhaps less jarring to most than to someone with a keen interest in architecture, development and building like myself, I was always struck by this dichotomy.

The familiar "old. new. old. new. old." rhythm of a Bellaire block

My parents built their house just as the second boom started to fade. At that time, we were only the second redeveloped property on our block. The houses on either side were built in the mid 1960s, as was the compact red brick home that used to occupy the lot. I can still see that block with all of the original houses on it in my mind, but it's changed significantly even since I left for college in 2010.
Everything's bigger in Texas

Though the building isn't quite as rapid as I remember it from my younger years, the decade since the
second boom cooled off has been good to Bellaire economically. Land values were high before the recession - around $300,000 for the average mid-block lot in 2006. Since Houston's strong recovery, the prices have gone astronomical: those same lots today fetch almost double the price tag.

Meanwhile, my old block continues to be built out (re-built out may be more accurate), as do many others. As the years go on, that "bingo" moment of spotting three houses in a row, each of distinctly different eras and styles, has become more and more prevalent.

Bellaire Bingo
I cannot say that I totally approve of the development patterns in my hometown, nor will I be surprised when the astronomical and always-increasing land values in Bellaire lead dollar-chasing developers and builders to begin demolishing the two story houses of the second boom. But what I can say is that these unique development patterns have created some of the most incredible lot-by-lot housing diversity I've ever seen.

FAVORITE DEVELOPMENT: Mueller, Austin


Austin has long been well known for its innovative forays into green building. One of the best examples of this sustainable development is the community of Mueller in East Austin.
The 711 acre site was previously occupied by Robert Mueller Municipal Airport, which was operational as Austin’s main commercial airport from 1930 to 1999, after which it was replaced by the bigger and better Bergstrom International Airport several miles to the north.

For several years, the prime, centrally located real estate sat unused, until city council approved a development plan for a unique mixed-use, new-urbanist community that follows the “Highest and Best Use” principle to a T.

The innovative master plan aims to accommodate 13,000 residents as well as 13,000 employees, with 4 million square feet of commercial space and 5,700 homes centered around 140 acres of open, public space.
A variety of home types are available, ranging from affordable to upscale, including apartments, condominiums, row houses, garden homes and more traditional, rear-loaded single-family. There seems to be a focus on creating a modern aesthetic throughout the project; commercial and public buildings are of a distinctly contemporary feel as are many of the homes, interspersed with homes of more classic and traditional architectural styles along the way.  
Community and walkability are heavily emphasized within the project. Bike lanes and pedestrian paths are at least equals to automobiles, a far cry from the typical automobile-friendly Texas development. A variety of sustainable measures were undertaken to ensure the project remains environmentally friendly, including a 1:4 ratio of trees to parking spaces in car parking areas to reduce the heat island effect and extensive recycling efforts during the deconstruction of the existing airport facility, among many others.
This responsible urban infill development is a landmark project that will hopefully pave the way for similar mixed-use, sustainably-minded and walkable projects across the state.

REAL ESTATE FAILURE: Highland Towers Collapse

The Highland Towers complex was located in the city of Ulu Klang in Malaysia. The development consisted of 3 high-rise residential towers constructed between 1974 and 1982. It was originally constructed at the base of a steep hill, which was terraced with a series of retaining walls in the late 1980s. An existing creek on site was diverted through a culvert.

In 1991, a new housing complex was constructed on the hill behind the project. Additional water runoff was diverted through the on-site culvert, exceeding its designed capacity and thus increasing the water content in the soils around the site. By 1992, water could be seen seeping over the retaining walls, suggesting a high level of saturation.
The two weeks preceding the collapse saw constant rainfall, further saturating the soils. At 1:35 PM on December 11, a landslide severely damaged the retaining walls and also piled up saturated soil on the base of Tower 1’s foundation. The instability of the soil and additional pressure caused the foundation to snap. Block 1 of the Highland Towers development, now completely separated from its foundation, toppled over and completely collapsed. In the end, 48 were dead and many more were injured. Blocks 2 and 3 were permanently evacuated.
The investigation revealed 5 primary causes for the collapse:
1. The drainage of the adjacent development 
2. Two weeks of continuous rainfall saturated the soil
3. Pools of water created unstable, swamp-like conditions at the base of Block 1
4. Piles supporting the building were not supported laterally
5. An underground limestone cave beneath the development collapsed, creating soil instability


An extensive lawsuit led to a RM 52 Million ($15.4 Mil USD) settlement; the engineer and architects’ names were withheld from the public. Some special considerations that may have prevented this tragedy. Retaining walls should be able to resist overturning even with the additional pressure generated by a landslide or any similar event. Additionally, the climate and erosion were not taken into effect. Additional planning for areas receiving so much rainfall, and the possible erosion accompanying it, has the potential to save lives.
