aside from the cost of land and baskets, what does it cost to build a course. more specificly, what does it cost for.........
1)teepads (18 of them needed, maybe even 36)
2)signage
3)benches for every hole
4)trash AND recycling containers at every hole
5) miscelaneious extras.............
The numbers on all of these can vary wildly depending on how rudimentary or posh you want to make your course, and whether you will have professional or volunteer labor to install all of the above. Just some suggestions...
1). teepads. Multiple pads are nice if you can afford them. Do realize that not every hole has the same teepad need. Uphill holes probably need a longer pad than others. Downhill holes may need to have a retaining wall built a few feet in front to prevent erosion. Less dynamic holes may be able to get by with only one pad.
2). signage. As I stated in the signage thread, go for durable but inexpensive to maintain. Deluxe signs may be neat, but in time elements or vandals will get to them. You may want to consider a course bulletin board with a map as a cheaper alternative.
3). Benches. - I've seen deluxe metal ones and things as simple as a 2" x 8" nailed into some poles. Go with what your budget will allow. If you don't have the money right away, this can be added later.
4). Trash cans - Not really needed on every hole. Every 2-3 holes will be fine. If the city picks up the park trash by garbage truck, they are best in locations the truck can reach (namely by a road). I like the idea of recycling containers, but most people are too damned lazy to care. Putting separate containers for each in a public park is asking for trouble. There will be recyclables in the trash container and vice versa.
5). Aside from the bulletin board aforementioned and maybe 4" x 4" post with hooks to hang bags, I can't think of any.
Wish I could give you a numerical quote for all this, but the variables are just so darned variable. Nonetheless, I think you can install a very deluxe course for under $20K.
