You're Invited! SW Watersheds Open House

Learn how we're working with partners to improve fish and wildlife habitat and infrastructure in SW Portland

You’re Invited to the annual Southwest Watersheds Open House! Come learn about SW Watershed Improvement Projects.

When: Wednesday, April 25, 2018, 5:30 p.m. to 7:30 p.m.

Where: Multnomah Center, gym - 7688 SW Capitol Highway

Stop by on your way home for refreshments, kids’ activities and information.

Environmental Services (BES) works with SWNI, the southwest community, other City bureaus, and partner organizations to develop plans and projects to improve water quality, address public interests, enhance fish and wildlife habitat, improve infrastructure, and restore watershed functions.

Please join BES and SWNI at this open house to discuss recently completed and current projects and give feedback on projects in planning and early design phases. Your participation helps shape plans to fit the neighborhood.

Stop by on your way home for refreshments and information about plans and projects to improve the health of SW Portland’s watersheds. Kids’ activities will be available, and all are welcome. To request translation services, contact Becky.Tillson@portlandoregon.gov.

A number of exciting projects in SW Portland will be highlighted, including:

Beaverton-Hillsdale Highway Stormwater Projects, Shattuck Phase

Stormwater improvements along Beaverton-Hillsdale Highway at Shattuck will protect Fanno Creek from stormwater pollution and increase pedestrian safety. Construction expected in summer 2018.

Boones Ferry Road Culvert Replacement Project

boones ferry culvert to be removed

Tryon Creek flows through a culvert under SW Boones Ferry Road that creates a barrier for fish moving to habitats in upper Tryon and Arnold creeks. Environmental Services is working with many partners to replace the culvert with a bridge. Construction expected in 2019.

Dickinson Park Stream Restoration

In collaboration with Portland Parks & Recreation, this BES stream restoration project will create wetland and floodplain benches, restore natural stream processes and function, and remove an abandoned pump house, footbridge, pipes and other structures. Construction expected in summer 2018. 

SW Capitol Highway: Multnomah Village to West Portland

BES is working in coordination with Portland’s Bureau of Transportation (PBOT) on street and stormwater improvements on SW Capitol Highway from SW Garden Home to SW Taylors Ferry roads. This project will improve safety and accessibility of travel while improving stormwater management and protecting water quality in local creeks and streams.

The one-mile stretch of SW Capitol Highway between SW Garden Home and Taylors Ferry roads has no sidewalks, bike lanes, or pedestrian crossings and limited stormwater infrastructure. For more than 20 years, community members have been advocating for better walking and biking conditions on SW Capitol Highway.

The Capitol Highway: Multnomah Village to West Portland project will provide pedestrian and bicycle infrastructure and stormwater management through the project zone and in certain areas within the surrounding drainage basins. Construction expected in 2019.

SW Capital Hwy preliminary design meeting

See you on April 25th!

 

Alien Plant Invader: Lesser Celandine

Learn how to spot and remove this troublesome invasive plant

Lesser CelandineThis friendly looking plant is popping up in lawns and parking strips across Portland, but don't be deceived!

It’s called lesser celandine. Like a lot of invasive plants, it is able to out-compete native plants. We need your help in the battle against invasives like this one.

Lesser celandine (Ranunculus ficaria) emerges earlier in the spring than many native plants, allowing it to overtake areas quickly. This advantage allows lesser celandine to form dense patches displacing native plants, destroying wildlife habitat and ruining lawns. Diverse native plants that provide nectar and pollen for pollinating insects and birds lose out. Lesser celandine also dies back in the spring, which leaves hillsides and stream banks vulnerable to erosion that pollutes our rivers and streams. 

Lesser celandine grows above-ground from November to April, and flowers from late winter to early spring. The leaves are dark green with silvery markings, shiny, succulent, and kidney- or heart-shaped. The bright yellow flowers are often confused with the look-a-like marsh marigold (Caltha palustris), which is a native plant not known to occur in Portland metro region. You can identify lesser celandine because of the three light green sepals behind its petals. Lesser celandine produces finger-like tubers that form underground and tiny bulblets under the leaves. The tubers, bulblets and seeds can all spread rapidly.

Removing this plant is tricky. All parts of the plant as well as any soil near the plant must be placed in a bag and thrown in the trash. Tubers and bulblets must be dug up and disposed. Due to this time consuming process, manual control (digging) is only recommended for small patches (less than six feet wide) and the site must be re-checked annually.  

Do not compost lesser celandine or try to save surrounding soil.  We encourage land owners to contact Environmental Services with any additional questions. Find more information on City of Portland’s page about lesser celandine and from the Plant Conservation Alliance

Invasive species affect us all. They damage our forests, our streams and rivers, and our property. Nationwide, damages associated with invasive species are estimated to be $120 billion each year. In Oregon, the control of invasive weeds and the cost of the damages they create amounts to about $125 million each year. We know that it costs a lot less to control new invasive plants before they become infestations, but we need everyone’s help. Read more here about the problems caused by invasive species and why BES is particularly concerned about their impact on water quality.
