It’s a great excuse for exercise and fresh air, and your help will add to the efforts making Johnson Creek healthier for people, salmon and other wildlife.

Date and time: March 5, 9am – 12pm, followed by a pizza lunch 

Location: Multiple sites (see map and register for a specific site)  

More details:  Tools, gloves, snacks, and instruction will be provided at each site. Children are welcome to join in with parental supervision.

Spring Cleaning at Flavel Ridge Wetland

0 Comments | Add a Comment

Environmental Services is working to stop illegal dumping that's threatening water quality and habitat in the Johnson Creek watershed

Flavel Ridge Wetland

On a sunny day last week, when the first red flowering currants were just beginning to bloom, a tucked-away city property got a much needed spring cleaning.

Flavel Ridge Wetland, near Johnson Creek on the Portland-Clackamas border, is home to Oregon salamanders, beaver, great blue heron, and even musk monkey flower, a native plant rare in the Portland area. Fed by groundwater seeps, and partially impounded by a beaver dam, the wetland provides cool, clean water to Johnson Creek year-round.

Oregon salamander safely relocated during recent cleanup

Because of its important role in maintaining cool water temperatures in Johnson Creek - especially critical during hot summer months - the Bureau of Environmental Services purchased the property in 2012. Since then, our revegetation team has begun removing invasive plants like Himalayan blackberry and clematis, and has planted 850 native trees and 1,050 shrubs.

Unfortunately, we recently noticed that tires and other debris had been illegally dumped in and around the wetland. It took a crew of five people the better part of a day to pull 131 tires out of the pond and haul furniture, rugs, drywall, televisions and other debris off the site. In total, over 5,000 pounds of debris was removed and recycled or properly disposed. We are now implementing deterrents to dumping at this site.

Tires racked up behind the beaver dam

Approximately a quarter of the tires removed from the property

Illegal dumping is a persistent problem across the metro area, and it impacts water quality and habitat in our natural areas. Please do your part and call police if you observe illegal dumping actively occurring. Do not confront the dumper directly. To report materials that have already been dumped call Metro at 503-234-3000 or report it online: www.oregonmetro.gov/tools-living/garbage-and-recycling/rid-patrol

FREE Rain Garden and Native Plant Workshops

0 Comments | Add a Comment

East Multnomah County Soil and Water Conservation District is offering another series of workshops for Portland homeowners

Every year, the staff at East Multnomah County Soil & Water Conservation District (EMSWCD) provide FREE rain garden and nature education classes across Portland. From the EMSWCD website:

Perfect for all levels of do-it-yourselfers, our FREE workshops highlight landscaping with native plants, water conservation, creative stormwater solutions and chemical-free gardening techniques that are good for people, water and wildlife. Most include a field trip to a neighborhood project or garden to see these principals in action.

This year Environmental Services and the Sunnyside Neighborhood Association will host a series of these workshops for residents of neighborhoods where managing stormwater on private property is an important part of current sewer rehabilitation projects.

Urban apartments can have nature, too

A cement courtyard becomes a hard-working rain garden and haven for birds

Environmental Services works with property owners in targeted areas in Portland to install rain gardens that help relieve local sewer problems.

A recent project in the Sunnyside neighborhood near SE 28th Avenue and Salmon Street removed about 500 square feet of asphalt and turned a bleak, urban courtyard area into a community asset. A rain garden, drywell, and patio made with pervious pavers replaced the asphalt area.

Now runoff from roof and paved areas soaks into the ground to keep stormwater runoff out of the sewer system, and apartment tenants have a natural, outdoor space to enjoy.

It was important to the property owner to plant a mix of native species to create habitat for beneficial pollinators and birds. The project directs runoff from 4,350 square feet of roof and paved area to the rain garden, and the 200 square foot patio lets rain soak through its pervious pavers into the ground to reduce stormwater runoff.

The rain garden keeps over 100,000 gallons of stormwater out of the sewer system every year to help reduce sewer backups, replenish groundwater and improve watershed health.  

Environmental Services uses partnerships like this to solve sewer capacity issues in neighborhoods with old, undersized pipes. These partnerships also save money for Portland sewer ratepayers by reducing sewer maintenance and wastewater treatment costs.
