bowls and transitions usually eat most of the budget......it' sucks when a bunch of old heads insist on a big coping bowl and they just skate it the first year the park is in, then it sits empty.....nice legacy....vs. a flat open area with a bunch of mellow stuff to skate.
ok unpopular opinion thread...
street eat the most space - which is inner city much more budget then construction cost flat/street vs Flow/Bowl.
300-400m2 you can get a phantastic bowl you can skate for the next 20years.
Streetwise you fit a flatrail and a ledge on it. Which is ok for warm up before street skating -but will not hype you
to spend the full day skating the park- which shoud be the purpose of a skatepark.
My real opinion is - if you want build a proper skatepark today - you need both. Not Street vs Transition anymore.
At least minimum 800m2 street better 1200m2 to have 4-5 proper and separated lines - so you can use the park with 20 people without getting in trouble + 300-400m2 Bowl.
Everything below is just a weak compromise and will not be a complete skatepark being able to satisfy all future users.
