Why aren't residents getting any help with the homeless in this neighborhood? With one look anyone can see that the neighborhood needs assistance. It takes one person to step out of their home to say hello and check in with these people. Bring out some food and befriend them.  See who they are and if they are safe people. If they aren't, then call the police and let them do their job. 15 people+ currently seek refuge in that park.
Fred Meyer and Albertsons have can returns and bathrooms. People without houses have needs and it is the city's job to put 2and 2 together and provide some leadership in providing a public shelter and weed out the criminals from the homeless population.
