About Crack Sealing
Asphalt Sealing, or sealcoating, is simply the process of laying a thin protective layer over asphalt-based pavement to give it a protective layer of protection against the elements: oil, water, and U.V. The positive effects of asphalt sealing have long been debated. Some claim that asphalt sealing increases the lifespan of the pavement, but again, there’s no evidence that backs up those claims. In fact, asphalt sealing can actually damage the pavement by creating cracks. The excessive water and oil that can be soaked into the asphalt also weaken its structural integrity. And, the chemical fumes emitted during asphalt sealing can also be harmful to humans.
With all of that in mind, it’s not surprising that a lot of business owners, when they set out to perform asphalt sealing, opt to go the non-per square foot route. For one thing, the costs are much lower, often no more than a few cents per square foot. And, the benefits of lower cost and improved performance are well-known. After all, if you want to save money, you want to reduce your operation costs, right?
But that brings us to our next question: Are asphalt sealing pads a good solution for parking lots, blacktop driveways, or other paved surfaces? As with any typical maintenance procedure, regular maintenance is the best way to reduce the cost of asphalt sealing. Sealing at least annually, will help keep dust, pollen, and other pollutants from making their way onto your paved surfaces. It will also help protect your driveway from water damage, as well as mold and algae growth, both of which cause a lot of problems to homeowners.
Now let’s take a look at how often you should reseal your asphalt surfaces, especially if you’re going to go the non-per square foot route. The key, again, is regular maintenance. And as it turns out, the best time to perform asphalt sealing and resealing is during the cold winter months. In fact, there’s even been some recent evidence suggesting that the best time for asphalt sealing and resealing is during the fall, when temperatures are quite low.
Why is that? It’s because fall is when most asphalt-based park finishes and protective coatings need to be applied. Asphalt-based park finishes are very weather-resistant, but that doesn’t mean that they’re impervious to the elements. In fact, the rainy spring weather can still cause problems, as can heavy snow, ice, and even dew. So, by applying the protective coatings only during the wet winter months, you’ll be doing your park and business no favors, and in the end, your asphalt sealing and resealing efforts will be wasted.
Here’s why: Asphalt seal coats are extremely dense. Think about asphalt sealing and resealing – it’s the same product, just in a different form. And, that means that you have to apply a lot less of it to achieve the same degree of protection. That’s why a lot of asphalt maintenance and repair companies (which specialize in asphalt sealing and resealing) will advise you to apply a minimum of three or four gallons of asphalt-base protectant per square foot of paved area. In other words, if you have a parking lot of ten thousand square feet, you’d want to apply three gallons per every twenty-five feet of paved area.
If you were to apply that kind of service to your own asphalt driveway, you could expect to pay anywhere from three to five dollars per square foot. Now consider that the average cost of asphalt sealing and resealing is only about two or three dollars per square foot. Multiply those two by the number of feet of asphalt you’re going to need to cover (per your parking lot, for example), and you quickly come to understand how much asphalt sealing and resealing would cost you. Applying the service yourself would cost you at least a thousand dollars or more. Not very appealing, I’d say.
But, don’t give up just yet – there are other ways to protect your asphalt driveway sealcoating and resealing investment, and they won’t cost you nearly as much, so don’t rule them out just yet. One of those ways is called flashings, which are like raised bumps along the edge of your driveway that will serve as an additional traction aid when you drive over it. The average cost of installing these would be about two hundred dollars, with the total installed cost running into the thousands. Another less expensive alternative is a thin film of asphalt seal coating that has a plastic protective layer between it and the ground, as opposed to flashing. It’s about as thick as standard asphalt, which would then have to be applied to your asphalt driveway sealcoating and resurfacing project in much the same way.
About South Los Angeles, CA
In 1880, the University of Southern California, and in 1920, the Doheny Campus of Mount St. Mary's University, were founded in South Los Angeles. The 1932 and 1984 Olympic Games took place near the USC campus at neighboring Exposition Park, where the Los Angeles Coliseum is located.
Until the 1920s, the South Los Angeles neighborhood of West Adams was one of the most desirable areas of the City. As the wealthy were building stately mansions in West Adams and Jefferson Park, the White working class was establishing itself in Crenshaw and Hyde Park. Affluent blacks gradually moved into West Adams and Jefferson Park. As construction along the Wilshire Boulevard corridor gradually increased in the 1920s, the development of the city was drawn west of downtown and away from South Los Angeles.
In the eastern side of South Los Angeles (which the city calls the "Southeastern CPA") roughly east of the Harbor Freeway, the area grew southward in the late 1800s along the ever longer streetcar routes. Areas north of Slauson Boulevard were mostly built out by the late 1910s, while south of Slauson land was mostly undeveloped, much used by Chinese and Japanese Americans growing produce. In 1903, the farmers were bought out and Ascot Park racetrack was built, which turned into a "den of gambling and drinking". In the late 1910s the park was razed and freed up land for quick build-up of residential and industrial buildings in the 1920s.
"By 1940, approximately 70 percent of the black population of Los Angeles was confined to the Central Avenue corridor"; the area of modest bungalows and low-rise commercial buildings along Central Avenue emerged as the heart of the black community in southern California. Originally, the city's black community was concentrated around what is now Little Tokyo, but began moving south after 1900. It had one of the first jazz scenes in the western U.S., with trombonist Kid Ory a prominent resident. Under racially restrictive covenants, blacks were allowed to own property only within the "Slauson Box" (the area bounded by Main, Slauson, Alameda, and Washington) and in Watts, as well as in small enclaves elsewhere in the city. The working- and middle-class blacks who poured into Los Angeles during the Great Depression and in search of jobs during World War II found themselves penned into what was becoming a severely overcrowded neighborhood. During the war, blacks faced such dire housing shortages that the Housing Authority of the City of Los Angeles built the virtually all-black and Latino Pueblo Del Rio project, designed by Richard Neutra.
During this time, African Americans remained a minority alongside whites, Asians, and Hispanics; but by the 1930s those groups moved out of the area, African Americans continued to move in, and eastern South LA became majority black. Whites in previously established communities south of Slauson, east of Alameda and west of San Pedro streets persecuted blacks moving beyond established "lines", and thus blacks became effectively restricted to the area in between.
When the Supreme Court banned the legal enforcement of race-oriented restrictive covenants in 1948's Shelley v. Kraemer, blacks began to move into areas outside the increasingly overcrowded Slauson-Alameda-Washington-Main settlement area. For a time in the early 1950s, southern Los Angeles became the site of significant racial violence, with whites bombing, firing into, and burning crosses on the lawns of homes purchased by black families south of Slauson. In an escalation of behavior that began in the 1920s, white gangs in nearby cities such as South Gate and Huntington Park routinely accosted blacks who traveled through white areas. The black mutual protection clubs that formed in response to these assaults became the basis of the region's street gangs.
As in most urban areas, 1950s freeway construction radically altered the geography of southern Los Angeles. Freeway routes tended to reinforce traditional segregation lines.
Beginning in the 1970s, the rapid decline of the area's manufacturing base resulted in a loss of the jobs that had allowed skilled union workers to enjoy a middle-class lifestyle. Downtown Los Angeles' service sector, which had long been dominated by unionized African Americans earning relatively fair wages, replaced most black workers with newly arrived Mexican and Central American immigrants.
Widespread unemployment, poverty and street crime contributed to the rise of street gangs in South Central, such as the Crips and the Bloods. The gangs became even more powerful with money coming in from drugs, especially the crack cocaine trade that was dominated by gangs in the 1980s.
Paul Feldman of the Los Angeles Times wrote in 1989:
He added that they believed such "distinctive neighborhoods" as Leimert Park, Lafayette Square and the Crenshaw District were "well-removed" from South Central.
By the early 2010s, the crime rate of South Los Angeles had declined significantly. Redevelopment, improved police patrol, community-based peace programs, gang intervention work, and youth development organizations lowered the murder and crime rates to levels that had not been seen since the 1940s and '50s. Nevertheless, South Los Angeles was still known for its gangs at the time. After leading the nation in homicides again in 2002, the City Council of Los Angeles voted to change the name South Central Los Angeles to South Los Angeles on all city documents in 2003, a move supporters said would "help erase a stigma that has dogged the southern part of the city."
On August 11, 2014, just two days after the shooting of Michael Brown in Ferguson, Missouri, a resident of South L.A., Ezell Ford, described as "a mentally ill 25-year-old man," was fatally shot by two Los Angeles police officers (see Shooting of Ezell Ford). Since then, a number of protests focused on events in Ferguson have taken place in South Los Angeles.
After the 2008 economic recession, housing prices in South Los Angeles recovered significantly, and by 2018, many had come to see South Los Angeles as a prime target for gentrification amid rising real estate values. Residents and activists are against market-rate housing as they have concerns that these projects will encourage landlords to sell, redevelop their properties or jack up rents. Under California law, cities can't reject residential projects based on these criticisms if the project complies with applicable planning and zoning rules. The construction of the K Line light rail through the neighborhood has stimulated the building of denser multistory projects, especially around the new stations. The NFL Stadium in Inglewood also encourages gentrification according to activists.
Real estate values in South Los Angeles were further bolstered by news that Los Angeles will host the 2028 Olympics, with many of the games to be hosted on or near the USC campus.
The City of Los Angeles delineates the South Los Angeles Community Plan area as an area of 15.5 square miles. Adjacent communities include West Adams, Baldwin Hills, and Leimert Park to the west, and Southeast Los Angeles (the 26-neighborhood area east of the Harbor Freeway) on the east.
According to the Los Angeles Times Mapping Project, the South Los Angeles region comprises 51 square miles, consisting of 25 neighborhoods within the City of Los Angeles as well as three unincorporated neighborhoods in the County of Los Angeles.
Google Maps delineates a similar area to the Los Angeles Times Mapping Project with notable differences on the western border. On the northwest, it omits a section of Los Angeles west of La Brea Avenue. On the southwest, it includes a section of the City of Inglewood north of Century Boulevard.
According to the Mapping L.A. survey of the Los Angeles Times, the South Los Angeles region consists of the following neighborhoods:
By the end of the 1980s, South Los Angeles had an increasing number of Hispanics and Latinos, mostly in the northeastern section of the region.
According to scholars, "Between 1970 and 1990 the South LA area went from 80% African American and 9% Latino to 50.3% African American and 44% Latino." This massive and rapid residential demographic change occurred as resources in the area were shrinking due to global economic restructuring described above and due to the federal government's decrease in funding of urban anti-poverty and jobs programs, and other vital social services like healthcare. The socio-economic context described here increased the perception and the reality of competition amongst Asians, African Americans, and Latinos in South LA. The results from the 2000 census which show continuing demographic change coupled with recent economic trends indicating a deterioration of conditions in South LA suggest that such competition will not soon ease."
In the 2014 census, the area of South Los Angeles had a population of 271,040. 50.0% of the residents were Hispanic or Latino, 39.7% were African American.
Many African Americans from South Los Angeles have moved to Palmdale and Lancaster in the Antelope Valley.
South Los Angeles has received immigrants from Mexico and Central America.
