On August 7th, 2008 the Salt Lake Valley Health Department passed a new ordinance which prohibits the use of any skate ramps on a residential property. The reasoning they have used to issue this ordinance is based on "Noise Pollution".
The ordinance can be found on the SLVHD website. It is Regulation # 21, and reads as follows...
4.5.21. Sporting Ramps. No person shall build or use nor shal any person cause, allow, or permit anyone to build or allow anyone to use any skateboard, roller blade, bicycle, or snowboard ramp or half-pipe or similar configuration within 800 feet of a dwelling, except within facilities that have been designated for such use by government entity.
