other crimes such as the 1984 gang-rape of two homeless women were barely reported. After World War II, it was feared that gay men perpetrated sex crimes and attracted violence. Other problems in the 1970s and 1980s included a drug epidemic, a large homeless presence, vandalism, and neglect. As crime has declined in New York City, many of these negative perceptions have waned. Safety measures keep the number of crimes in the park to fewer than 100 per year , down from approximately 1,000 in the early 1980s. Some well-publicized crimes have occurred since then: for instance, on June 11, 2000, following the Puerto Rican Day Parade, gangs of drunken men sexually assaulted women in the park. Other issues Permission to hold issue-centered rallies in Central Park, similar to the be-ins of the 1960s, has been met with increasingly stiff resistance from the city. During some 2004 protests, the organization United for Peace and Justice wanted to hold a rally on the Great Lawn during the Republican National Convention. The city denied an application for a permit, stating that such a mass gathering would be harmful to the grass and the damage would make it harder to collect private donations to maintain the park. A judge of the New York Supreme Court's New York County branch upheld the refusal. During the 2000s and 2010s, new supertall skyscrapers were constructed along the southern end of Central Park, in a corridor commonly known as Billionaires' Row. According to a Municipal Art Society report, such buildings cast long shadows over the southern end of the park. A 2016 analysis by The New York Times found that some of the tallest and skinniest skyscrapers, such as One57, Central Park Tower, and 220 Central Park South, would cast shadows that can be as much as long during the winter, covering up to a third of the park's length. In 2018, the New York City Council proposed legislation that would restrict the construction of skyscrapers near city parks. Impact Cultural significance Central Park's size and cultural position has served as a model for many urban parks. Olmsted believed landscape design was a way to improve the feeling of community and had intended the park as the antithesis of the stresses of the city's daily life. The Greensward Plan, radical at the time of its construction, led to widespread changes in park designs and urban planning; in
