Skatedot
The smallest skating areas are less than 1500 square feet, which is a little smaller than half of a college basketball court. This kind of skate area is often referred to as "skateable terrain" and could include existing structures that were suitable and appropriate for skating. Conceivably, a person could walk through a skatedot on the way to work.
Skatespot
A Skatespot is larger than a skatedot and according to the Park's Department's planning process, is described as "providing for separation of ... vehicular and pedestrian access." In other words, an area pedestrians would not likely wander into inadvertently. Skatespot sizes range from 1500 to 10,000 square feet, and the Ballard Bowl qualifies as a skatespot, at about 4200 square feet.
For purposes of comparison, Bergen Place Park, at the corner of NW Leary Way, 22ND Avenue NW and NW Market Street, is about 8700 square feet in size.
District skate park
A District skate park is the next largest size of skating area, measured between 10,000 and 30,000 square feet. A district skate park would offer separate features appealing to a range of skateboarding skills, unlike a skatespot, which might only offer one feature, such as a bowl. 30,000 square feet is about half the size of the Ballard Commons.
Regional skate park
A regional skate park would be anything larger than 30,000 square feet in size, offer the most skateable features and could even host concessions for skaters and viewers. The city of Denver has a regional skatepark 50,000 square feet in size. Reportedly the largest regional skatepark in the world is in Shanghai China, covering 140,000 square feet.
The focus of the Skate Park Advisory Task Force is primarily on Skatespot and District size skate parks.
