It is unlawful to possess or drink alcohol in Portland Parks without a permit. Canned or bottled beer and wine are the only types of alcohol allowed even with a permit; no kegs or hard liquor. Sale or serving of alcoholic beverages requires a Special Use Permit, proof of liability insurance, and in some cases, approval by the Oregon Liquor Control Commission.
Music and Amplification Systems
Radios, tape and CD players must be kept at a sound level that does not go beyond the area reserved. Sound amplification of any kind requires self-monitoring by permit holders and excessive noise will result in a loss of security deposits. Moderate amplification of music is allowed on a case-by-case basis but a Noise Permit may be required. The City’s Noise Control Officer (503) 823-7350 can answer questions concerning sound amplification in more detail.

If you care about the environment, here’s why you should …
Scoop the Poop
Doggie-doo isn’t just smelly and yucky to step in - it damages the land. Dog feces have a high nitrogen content, which fertilizes and spreads nitrogen-loving invasive weeds at the expense of native plants. Poop fouls water sources with bacteria and harmful microbes and speeds the growth of algae in creeks and rivers. Parasites in the droppings can be a hazard to wildlife.
Keep Your Dog Leashed
All dogs are predators. No matter how harmless your dog seems to you, wild birds and animals are acutely aware of dogs on the loose and often take escape measures – running, burrowing, climbing, flying. These disturbances can have serious consequences for wild creatures, causing extra stress and the use of precious energy that may make the difference between life and death. Free-ranging dogs can also attack and kill wildlife.
Stay on the Trail
When dogs run and play off the trail, they trample native plants and destroy habitat for ground-nesting birds. When they play in streams, they stir up sediments that can make it difficult for fish and other aquatic organisms to breathe.
When streamside shrubs and plants are destroyed, they can no longer provide shade for the stream or cover for wildlife. The lack of shade causes water temperatures to rise, which can be lethal for some species of fish. Also, streamside plants provide habitat for insects which are an important food source for fish.
