A Conversation with Mitch Bixby about Invasive Plants
Mitch Bixby is a long-time employee with City of Portland’s Bureau of Environmental Services (BES). He is the Early Detection/Rapid Response (EDRR) field specialist, with a particular focus on heading off new-to-Portland plant species that may be invasive. Every Spring Mitch works on controlling Garlic Mustard in many SW neighborhoods including Arnold Creek.
Mitch will give us an overview of the EDRR program and explain why some invasive plants like Garlic Mustard are on the list and why some others, like Ivy, are not. Mitch will also answer any questions about invasive plants, so if you need help with identification, or if you are looking for tips on control strategies, or if you want to learn more about what the City is doing, please zoom into our April meeting.
SW Boones Ferry Rd Walkway
Southwest in Motion (SWIM) Project BP-40 Boones Ferry Walkway will improve pedestrian safety along SW Boones Ferry Rd, between SW Orchard Hill Rd and our local grocery and shopping center Oswego Towne Square.
The project is in the construction phase. The construction will take place from March – May 2025.
View Portland Bureau of Transportation (PBOT) project website.

The safe shoulder will be approximately 730 ft in length and 5 ft in width. PBOT will install concrete separators to protect the walkway where possible, while accommodating for driveways and bus stops, approximately 425 ft in length. PBOT decided to update the design after hearing feedback from the Arnold Creek Neighborhood Assocation to include shoulder widening and extend the path north on SW Orchard Hill Rd.
