What you see here is roughly about $30k worth of Huna ramps (including the bench, picnic table and grindrail)
The total skateable surface of every item adds up to 385 sq ft. (A call to Huna got that figure)
Divide the sq footage from the price and you come up with $77.92 per sq ft of skating surface!
Just because you place a few obstacles on a 10,000 sq ft pad, it does not mean that you have a 10,000 sq ft skatepark!
The true skating surface of modular is the surface area of the ramps/boxes/rails. The above picture features obstacles that are 2-3' high and only 8 ft wide.
Not much of a challenge and not a good value for your dollar either! An all concrete skatepark designed/built by a professional skatepark company is a better deal.
