R ules will be posted regarding level of control required and people will be expected to obey. This will be based mostly on honor system and peer pressure. Number of dogs any one person can have off-leash in the park at one time will be limited. There are no guarantees that every dog will behave as reliably as it has at home and that an owner won't be caught off-guard and unable to call their dog back to them. The next time they might try the training area instead.
Many people enjoy dogs.
Dog owners are just another user group, similar to skateboarders in the skate park, swimmers, tennis players, baseball players, soccer players, kids using the playgrounds, golfers, etc., and deserve a special place in the same way. That's a sizable chunk of the park user population. Usually owners and dogs come to the park in a trickle, sprinkled throughout the day, so users at any one time may not look gigantic, but when parks have been monitored by gate checker, they find the numbers are much more sizable than originally guessed. The land that is under consideration for the park in Cedar Rapids is land that is currently unused because it is not ideal for other park uses. Dogs will naturally bark when they are in the midst of true playing and joyous expression, however the size of park should minimize the impact of this on neighbors and the numbers of dogs at any one time will probably not make this a problem in any case.
