The City is looking at updating the municipal codes to deal with dog off-leash areas. They will be holding a series of public meetings to discuss the draft proposal and seek input to make sure it works for the dog park community. The main points seem to be adding some personal responsibility for the actions of your dog, and limiting each person to three dogs.
The draft is here. The first meeting will be at the Morley Field Recreation Council regular meeting on April 7th at 6pm at the Balpoa Park Activity Center. Please note that due to public forum requirements, they will only be discussing this municipal code adjustment, not all dog off-leash area issues (like turf maintenance).
