Greetings fellow city-builders and welcome to another Sunset Harbor Dev Diary!

This time, we look at new maps and policies as well as the new unique building, all of which are coming in Sunset Harbor. Let's start with the maps!

Sunset Harbor introduces five new maps to the game. The maps differ from each other significantly, and each one brings along new challenges into your city-building. Are you ready to take the first steps and start on this journey that will take us from serpentine river filled swamp lands all the way to something we've never done before in Cities: Skylines, a desert? Join us!

Located in a large, open bay area overlooking the vast ocean, Azure Gulf offers good outside connections by ship. With small lakes and several rivers of various sizes, Azure Gulf is an ideal place to start a booming Fishing Industry. This temperate map is also rich in ore and forests.

With its Boreal theme, Crater Falls is a large crater area surrounded by a mountain range with several trickling rivers flowing into small lakes in the middle. Cliff faces rising from the riverbeds, ever flowing rapids, deep lakes and beautiful waterfalls all invite fishers to come and seize the day and take their pick from the different types of fish the waters hold. In addition to providing good Fishing Industry possibilities, the mountains are rich in ore and there are plenty of forests and fertile land areas between the rivers.

Crater Falls

Made possible by the new Inland Water Treatment Plants and the Water Tower, Desert Oasis is a map with no flowing water. Surrounded by an endless desert hiding only a few oases, this map offers a completely unique place for a city. With so little fresh water, the Tropical Desert Oasis may not be best for fishing, but the dunes are rich in both ore and oil.

As the name suggests, Fisher Enclave is a great place to start a Fishing Industry. With huge bodies of still water surrounding it, Fisher Enclave consists of several small and a few larger islands. This European themed map filled with forests offers mainly two kinds of fish. Just be careful, as the still waters are easily polluted.

While its defining feature are the flowing, serpentine rivers carrying every type of fish, Swamplands also offers large flat areas suitable for building. This map with a Boreal theme is rich in forests and fertile land. Take care, though, as you might accidentally make the rivers overflow, flooding large areas of land.

Sunset Harbor also includes 6 new policies, four of which are fishing related. The Fishing License policy creates residential tax income from the city selling affordable fishing licenses to its citizens. The policy unlocks at Milestone 3, and it increases crime and decreases citizen happiness by a small amount. With the Sustainable Fishing policy, the fishing industry can take steps to ensure that the fish population sizes stay at healthy levels. This increases the price of fish sold but lowers the fish yield, as fishing boats leave more fish in the ocean to minimize the environmental impact. With the Dolphin-safe Fishing policy, the fishing industry adopts new techniques to ensure minimal dolphin fatalities resulting from fishing. This increases citizen happiness but also lowers the fish yield. Sustainable and Dolphin-safe Fishing both unlock at Milestone 6. When Algae-based Water Filtering is enabled, the water service network uses algae as a natural filtering system. This policy is unlocked after an Algae Farm is built and Milestone 5 is reached. It increases the purification level of drain pipes and water treatment plants but also increases the water facility upkeep cost and decreases algae farm production.

After building an intercity station or terminal, you can increase bus-based tourism with the Tourist Travel Card policy. The city's tourism department then starts a campaign to increase tourism in the city by offering affordable intercity bus tickets to people living in the surrounding cities. This increases the upkeep costs of the Intercity Bus Station. The Airplane Tours policy is available after building the new unique building (more of which in next part of the diary). By opening its door to tourists, the building's attractiveness and entertainment are increased. The downside is higher levels of noise pollution. These two city policies unlock at Milestone 6.

Now is the time to finally reveal the new unique building. Can we get a drum roll, please! Sunset Harbor's unique building is the Aviation Club! It consists of a small terminal, an air traffic control tower and a runway for light aircraft. Planes take off, fly high into the sky, circle around the city and land safely back on the runway. Local aviation hobbyists and owners of small planes can use the field as a base for recreational flying within the city's limits. The Aviation Club also attracts tourists and increases the city's attractiveness and entertainment. Once unlocked at Milestone 6, the building is found in the Unique Buildings build menu, under Level 5 Unique Buildings tab.

That's all for this Dev Diary. We hope you are as excited about the new maps and the unique building as we are! Tune in again next time when we look at the upcoming free content.

Hello! Welcome yet again to another Cities Skylines: Sunset Harbor Dev Diary! So please, stay a while and... read!

In this Dev Diary, we'll be taking a look at the Waste Transfer System and Inland Water Treatment features coming with the Sunset Harbor DLC!

The Garbage city service is getting expanded with a Waste Transfer System feature. Players have at times experienced difficulties with the Landfill site's reach or the fact that it creates highly polluted areas in the middle of the city. The Waste Transfer System is an upgrade to the base game's garbage service, and it focuses on solving these problems and improving the gameplay in relation to the Garbage city service. While the base game Landfill Sites and Incinerators, along with Green Cities DLC Recycling Centers, can be used alongside the new Waste Transfer System, the new system's core idea is to make handling garbage easier and more flexible without compromising the city layout as drastically.

The Waste Transfer System contains a Waste Processing Complex and a Waste Transfer Facility along with two new vehicles, the Waste Transfer Truck and the Waste Collection Truck. With the new additions, you can build a Waste Processing Complex far away from your beautiful city and extend its reach by building smaller, less polluting Waste Transfer Facilities in the city.

If you have either the Sunset Harbor or the Industries DLC enabled, you will find that the Garbage build menu has been renamed to Garbage and Industry and that's where, under the Garbage tab, all the new Waste Transfer System buildings can be found once they are unlocked at the Grand City milestone (9).

A Waste Processing Complex in a spot perfect for processing garbage: far away from the city, in a industrial district.

When you have unlocked the Waste Transfer System buildings, you can begin using them by building Waste Transfer Facilities at essential locations around the city. When facilities and landfills are getting full, it is a good idea to build a Waste Processing Complex, which will begin sending out Waste Transfer Trucks to pick up garbage from any Landfill Site, Recycling Center, Incineration Plant or Waste Transfer Facility. It is worth noting, however, that a Waste Processing Complex can't work on it's own, as it doesn't collect garbage directly from buildings, only from other garbage-storing facilities.

Waste processing chain differences between base game garbage service and the Waste Transfer System.

The Waste Transfer System will come in handy for example when the city is looking to expand, when the roads are getting filled with garbage trucks, or when landfill sites just can no longer reasonably keep up with the amounts of garbage the city produces. By having Waste Transfer Facilities scattered across the city, garbage can be collected from buildings more swiftly, while a centralized Waste Processing Complex then handles the collection of garbage from those temporary holding sites. This keeps pollution away from city and saves up space for more zoning possibilities.

A Waste Transfer Facility can operate safely even in residential neighborhoods.


The Inland Water Treatment Plant is an expansion of the Water service, and it enables you to build cities completely inland, far away from open water sources. With the Inland Water Treatment Plant, your city can process waste water without pumping sewage into lakes, rivers or the ocean. The Inland Water Treatment Plant does create high ground pollution however, so placing it next to residential areas or bodies of water is not advisable. Advanced variants of the Inland Water Treatment can process higher quantities of sewage while creating less ground pollution. The Eco variant produces even lower ground pollution levels but also has a lower drain capacity.

The Inland Water Treatment Plant and all of its variants can be found under the Water and Sewage build menu. The Inland Water Treatment Plant and the Eco Inland Water Treatment Plant are unlocked at city milestone 0. The Advanced Inland Water Treatment Plant is unlocked at city milestone 8, and finally the Eco Advanced Inland Water Treatment Plant is unlocked at milestone 10.

Large Water Tower compared to its smaller sibling.

The Inland Water Treatment Plant is built on land, alongside a road. It can be connected to the water network simply by building water pipes to its connector node underground, in the exact same way as every other water pump, tower and drain pipe. Once functional, the Inland Water Treatment Plant starts generating ground pollution around the building but purifying the water.

Also included in the extended Water city services is the Large Water Tower. It shares the same functionality as the base game Water Tower, but has a much higher pumping capacity! And just like the base game Water Tower, the Large Water Tower can be placed anywhere on the ground. Once placed and connected to the water pipe and electricity networks, it will start pumping water. Ground pollution affects the quality of water, and if water is pumped from an area with ground pollution, citizens will become sick.

With these additions to the Water and Sewage city services, cities can now also form skylines even in places where plenitudes of water aren't available!

An Inland Water Treatment Plant and its Advanced version take care of the sewage but produce a lot of ground pollution! Better place these away from the city!

And that wraps it up for this Dev Diary. We look forward to seeing you again on the next one, where we will be taking a more in-depth look at the new maps, policies and the new unique building!
