Planning for cities with linear skylines
Shown below are some of the cities around the globe that have linear skylines. While these can be visually impressive, especially when set as a backdrop against the coastline or mountains, they also can be challenging from a planning and infrastructure perspective, unless they are adapted properly to address this unique urban landform.

Bear in mind, that linear skylines are not just a coastal or narrow valley phenomenon. Las Vegas is perfect example of an inland city with a very linear skyline that resulted in part due to how the city developed as a desert oasis along a single major corridor. Other examples may result from topographic settings like narrow mountain valleys, river valleys, peninsulas, or islands.
The length of linear skylines can tend to dissuade walking, as the distances between sites can be intimidating. Furthermore, if the focus is too concentrated, primary streets that run the length of the skyline, such as the Las Vegas Strip, can become overwhelmed by traffic and people.

That is why it is important to have viable and efficient alternatives — light rail, buses, bicycling routes, trollies, or as Las Vegas has developed, a monorail line. Safe crossings of busy thoroughfares is also needed. As the image are shows, overpasses or tunnels for pedestrians may be necessary. Otherwise, crosswalks must be set up to allow time for safe movement across the avenues.
In some ways, a linear design can be efficient when it comes to utilities, because they can be focused in a narrower area. However, they must constructed of sufficient size and scale to handle the concentrated needs for water, sewer, electricity, gas, etc. Otherwise, the streets and roads may be constantly torn up to increase capacity. Utility managers will also need to address verticality of the service area, to assure water pressure and other services are maintained at their highest levels.
Another important factor to consider is public safety, particularly from fire-fighting and emergency response standpoints. By their very nature, linear skylines tend to be more dense and as a result taller. This is very evident from the photos provided below. How public safety services address the inherently denser and taller structures is critically important for assuring public safety is always a top priority for avoiding potential tragedies.
Another factor to consider for tourist-oriented linear skyline is the variations between on and off-season. Any and all planning efforts will need to take this into account as the extent of impacts can fluctuate greatly over a calendar year.

What is likely to be the most linear (and perhaps vertical) skyline of them all is the controversial 106 mile long, new city of Neom being constructed in Saudi Arabia (see images above and below. How this project will eventually turn out and whether it will achieve the stated goals of livability and sustainability remains to be seen. If it is successful, it may be a defining development for the future. Otherwise, it could be a precautionary tale to avoid excepting very specialized circumstances.

As has been noted throughout this post, linear skylines can have their challenges. How effectively these are addressed will help determine whether or not the infrastructure and services can meet the concentrated demand. At the same time, the opportunities are not quite as apparent. To this retired planner, ambitious individual developments that are overly lengthy or excessively vertical may not achieve their “lofty” goals. Similarly, it remains to be seen how efficient and effective such a narrow, dense and lengthy urban form can be.
Peace!
