Reducing Noise Pollution In Cities: Strategies For Success

In the city-building game Cities: Skylines, noise pollution is an inevitable part of the experience. While it cannot be eliminated, there are strategies to reduce its impact on your citizens. Noise pollution is caused by traffic, commercial and industrial areas, city services, and leisure buildings. Left unchecked, it will decrease citizen happiness and well-being, and even cause illness and death. To mitigate these negative effects, you can employ several strategies. Firstly, keep heavily trafficked areas, such as highways and commercial centres, away from residential zones. Trees can act as sound barriers, reducing noise pollution from busy roads and business centres. Sound barriers can also be implemented on highways. Create policies that restrict heavy traffic and combustion engine vehicles from certain districts, and consider using speed bumps to reduce vehicle speeds and, consequently, noise pollution. Additionally, route busy roads underground, if possible, as this will significantly reduce the noise they produce. Proper zoning is crucial. Ensure noise-polluting buildings and businesses are located away from residential areas, and use office zones as sound barriers since they produce little to no noise pollution. Lastly, while trees can help reduce noise pollution, they must be used in large numbers to have a significant effect.

Use trees and parks as buffers

Trees and parks can be used as buffers to reduce noise pollution in Cities: Skylines. While individual trees do not have a significant impact on noise reduction, creating a park asset with a group of trees can help mitigate sound pollution.

To effectively use trees and parks as buffers, it is recommended to create a buffer zone between residential and commercial areas. This can be done by leaving a space of a few squares between the two zones and filling it with trees and pedestrian paths. This strategy not only helps reduce the spread of noise pollution but also minimises traffic.

In addition, tree-lined roads, particularly those with decorated versions of 2, 4, and 6-lane roads, can also contribute to noise reduction. These roads not only improve the aesthetics of your city but also help to decrease traffic noise.

When placing trees, consider using larger trees, such as redwoods, as they may be more effective at blocking noise from high-rise buildings. Additionally, you can use the noise overlay feature to observe the impact of your tree placement on noise pollution levels.

By strategically placing trees and parks, you can create a more aesthetically pleasing and healthier city for your citizens in Cities: Skylines.

Zone buildings properly

To reduce noise pollution in Cities: Skylines, it is important to zone buildings properly. This means keeping noisy areas away from residential zones to prevent your citizens from getting sick.

Commercial Zones

Commercial zones produce varying levels of noise pollution. High-density commercial zones produce medium levels of noise pollution, while low-density commercial zones produce low levels.

There are also different types of commercial specialisations that produce different amounts of noise. Generic commercial zones produce medium noise pollution, which decreases as the buildings level up. Leisure and tourism zones, regardless of density, produce medium to high levels of noise pollution. Organic and local produce zones, on the other hand, produce no noise pollution. The only noise generated in these areas comes from trucks bringing in supplies.

Industrial Zones

Generic industrial zones produce high levels of noise pollution, which decreases as they level up. Farming industries produce no noise or ground pollution, but they provide only a slight tax boost and require a lot of water. Ore industries produce high noise and ground pollution, while oil industries produce high noise and very high ground pollution but offer the best taxation boost. Forestry industries create very high noise pollution but no ground pollution, and they also provide a tax boost, but they require a lot of electricity.

Office and Residential Zones

Both high- and low-density residential zones, as well as office zones, produce no noise pollution. Any noise in these areas will be from traffic or public transportation. Office zones can be used as a buffer between residential and high-commercial zones to help reduce noise pollution.

Implement sound barriers on highways

Implementing sound barriers on highways is an effective way to reduce noise pollution in Cities: Skylines. Here are some strategies to consider:

Understanding Noise Pollution

Firstly, it is important to understand that noise pollution is an inevitable aspect of building a city in the game. Almost every unique building and district will generate noise pollution to some extent. This can have negative consequences, such as making your citizens ill if they live too close to high-noise areas. Therefore, it is crucial to manage noise levels effectively.

Highways with Sound Barriers

Highways with sound barriers can significantly block the noise generated from traffic. These sound barriers are specifically designed to reduce the amount of sound that escapes from the highway, making them ideal for cutting down noise pollution in your city. Place these highways strategically to mitigate noise in high-traffic areas.

Strategic Tree Placement

Trees can also be used as a natural sound barrier and are an essential tool for reducing noise pollution. Place trees alongside roads and highways to create a buffer between the noise source and residential areas. Consider using tree-lined roads, which not only reduce noise pollution but also increase land value. You can also use trees to fill empty spaces and make your city feel more realistic.

Zoning and District Placement

Proper zoning and district placement play a crucial role in mitigating noise pollution. Keep noise-generating districts, such as industrial areas, away from residential zones. Create buffer zones by using office zones, which produce no noise pollution, between noisy areas and residential zones. This will help to reduce the impact of noise on your citizens.

Mods and Assets

If you're looking for more options, consider using mods or custom assets. Some mods allow you to reduce noise pollution or implement sound barriers that are not available in the base game. Custom assets can also be used to create sound barriers with specific appearances, such as walls or parks, to match your desired city design.

Create policies to prevent heavy traffic in certain areas

To prevent heavy traffic in certain areas and reduce noise pollution in Cities: Skylines, you can implement the following policies:

Ban Heavy Traffic

The "Ban Heavy Traffic" policy is a district-specific policy that prevents big cargo trucks from using roads within designated areas. This policy is ideal for residential neighbourhoods with higher traffic and smaller roads. It's important to note that this policy doesn't apply to your entire city but only to specific districts. Additionally, it doesn't remove trucks from your city and has no effect on highways.

Encourage Alternative Transportation

Encourage your citizens to use alternative modes of transportation by implementing policies like free public transportation. This will make public transport a more attractive option, reducing the number of cars and trucks on the road. However, keep in mind that free public transportation will also make this service unprofitable, so ensure your city can afford this policy.

Expand Public Transport Options

As your city grows, expand your public transport system to include bus routes, metros, and train lines. This will provide your citizens with more options to get around without relying on cars. Consider adding underground train and metro lines to areas that are already built-up, and remember to add stations where needed.

Create Pedestrian Pathways

Construct pedestrian pathways to provide walking route alternatives to roads. This will make it easier for citizens to get around on foot, reducing the number of vehicles on the road. Place pathways in areas where space permits, connecting two roads that aren't already linked.

Implement Vehicle Restrictions

Instead of restricting traffic in entire districts, you can use the TM:PE mod to apply "Vehicle Restrictions" to certain roads. This allows you to prohibit trucks from using streets with residential buildings, redirecting them to streets with commercial buildings instead.

Plan Your City with Traffic in Mind

Finally, remember that city planning is crucial to managing traffic. Design your districts with traffic flow in mind, ensuring traffic can move freely between zones. Consider creating bypass highways to redirect heavy traffic away from residential areas.

Use office buildings as sound barriers

Using Office Buildings as Sound Barriers in Cities: Skylines

Office buildings can be used as sound barriers in Cities: Skylines to reduce noise pollution. Here are some strategies to implement this technique effectively:

Understanding Noise Pollution

First, it's important to understand that noise pollution is an inevitable aspect of the game. You can't completely eliminate it, but proper planning can help minimise its impact on your city. Noise pollution is caused by certain districts and buildings, and it can make your citizens ill if they live too close to noisy areas.

Office Zones as Barriers

Office zones are ideal for creating 'barriers' between noisy areas and residential zones. Unlike commercial zones, office zones do not generate noise pollution themselves. They serve as industrial buildings in terms of demand, providing jobs for your educated workforce. It is recommended to have a few office areas spread throughout your city to control noise levels.

Placement Strategies

When placing office buildings, consider using them as buffers between residential zones and noisy areas such as highways, industrial zones, or commercial zones with high noise pollution (e.g., tourism and leisure). Leave a space of at least one to three blocks between the office buildings and residential areas to effectively reduce noise levels.

Combining with Other Techniques

Combining office buildings with other noise reduction strategies can further enhance their effectiveness. For example, you can place trees or parks near office buildings to create additional sound barriers. Additionally, consider upgrading roads to tree-lined roads, which can reduce noise pollution and increase land value.

Mods and DLCs

If you have access to mods or DLCs, there are additional options available to reduce noise pollution. The Green Cities DLC, for instance, allows you to place IT clusters within office zones, adding skyscrapers to your city skyline while generating more tax revenue and providing jobs. There are also mods that can reduce or eliminate noise pollution, such as the "ultimate mod" or "pollution reducer."
