MHCC Salmon Safe Projects
AT A GLANCE
The Salmon Safe Projects at Mt. Hood Community College are a series of projects that improve wild salmon habitat and water quality. This project is a partnership between the Sandy River Watershed Council, MHCC, and other regional partners.
Beaver Creek, the lowermost tributary to the Sandy River, and its tributary Kelly Creek, flow through and meet on MHCC campus. These creeks support populations of wild salmon and steelhead, despite urban and agricultural development in the Beaver Creek watershed.
Project partners recognized that scaled green infrastructure could convert MHCC from one of Gresham's largest single sources of stormwater runoff into a community leader in clean water management. Site specific actions seek to meet key goals:
Improving water quality and habitat around Beaver and Kelly Creeks
Creating a living learning laboratory of sustainable practices for MHCC students, programs and the community
Enhancing MHCC's leadership in sustainability and climate resiliency
The creation of these goals and the implementation of projects and changes that support them has made MHCC the first community college in the country to earn the Salmon Safe certification. It is also the first institution to gain the designation in Gresham.
To maintain the Salmon Safe certification MHCC and partners will:
- Install rain gardens and other facilities to treat polluted stormwater before it flows into the creeks.
- Look at changing the pond to improve water quality, especially to lower water temperature.
- Reduce pesticide use on campus (something MHCC has already been doing)
Beginning in 1965, construction of the MHCC campus transformed a former agricultural area into the current campus, which includes 57 acres of impervious surface. The 1960’s campus design did not take into consideration the impact of stormwater heating up and collecting pollution from parking lots, roofs, and other hardscapes as it flows untreated into habitat occupied by salmon in Beaver and Kelly Creeks. As a result, the MHCC campus drains 60 million gallons of polluted stormwater to the creeks annually, degrading water quality and fish habitat.
Kelly Creek splits the north end and south end of campus. To make travel easier between the two ends of campus, a dam and causeway were built over the creek. The dam created the Kelly Creek pond, which is managed as a recreational fishing resource. The pond heats up water temperature downstream of the dam by four degrees Celsius in the summer. This raises the temperature above what a normal juvenile salmon can survive in. Partners are conducting a study to see if it is possible to change the dam to improve water quality and habitat for salmon.
East Multnomah Soil and Water Conservation District funded an opportunity analysis of the MHCC campus in the spring of 2017. The consultants performing the analysis, Herrera Environmental Consultants, identified 22 different project opportunities. Partners prioritized opportunities based on a series of impacts: volume of stormwater treated, improvements to habitat and tree canopy, cost, opportunity for student and public involvement, and long-term sustainability.
The first Salmon Safe project kicked off in May 2018. With the guidance of non profit Depave 130 volunteers helped remove asphalt from seven spaces in MHCC's front parking lots to absorb rain water and give large older trees room to grow. These spaces were planted, again with volunteer help, in the Fall of 2018. To read more about the Depave for Salmon project go here.
Also, during the summer of 2018, rain gardens, bioswales, and planters were constructed in two parking lots. This project alone will treat nearly 2 million gallons of stormwater a year.
Project partners will continue to work together to complete additional projects as plans are completed and funding is available. Monitoring gauges installed in drainage pipes will track water volume, quality and other indicators as stormwater retrofits occur.
Partners and Funders
The Salmon Safe projects are a collaborative effort between MHCC, the Sandy River Watershed Council and a range of regional partners. The Salmon Safe Clean Water project is funded entirely by external grants from: East Multnomah Soil and Water Conservation District, Metro, City of Gresham, Spirit Mountain Community Fund, and the Oregon Department of Environmental Quality.
Long Term Impact
During their spawning surveys, on Beaver Creek, MHCC fisheries students often find that salmon die before they can lay their eggs. This may be because the salmon return in the fall when the rains begin again. The first fall rains wash all the pollution that accumulates on the roads and parking lots during the dry summer into the creek, at the same time as salmon are returning from the ocean, which may be enough to kill the salmon after their long journey.
The Clean Water Retrofit rain gardens and other stormwater management projects will help reduce pollution and stream temperature. Beaver Creek's salmon will have a healthier habitat where they can lay their eggs, and once hatched their young will have a better chance to survive, migrate to the ocean, and repeat the life cycle. With all priority actions completed, the MHCC Salmon Safe project's goal is to clean, cool and capture a billion gallons of runoff over the thirty-year project life. Improved passage via culvert projects nearby will help the salmon return upstream to spawn. Little by little, Salmon Safe project partners, with the help and support of the community, hope to restore Beaver and Kelly Creeks to healthy habitat where many species of native fish and wildlife can thrive.

MHCC English Students Respond to Salmon Safe Projects
On January 28th, 2020, Sandy River Watershed Council staff member Melissa led a tour of the Mt. Hood Community College campus for five students of the MHCC WR 122:05 English class and their instructor. During this tour students engaged in discussion and inquiry about the Salmon Safe projects and why these projects are happening on their college campus. The following blog post is the students response to what they learned that day.
Updates from the Field
Breaking New Ground this Summer
This summer, we are preparing for the next round of Salmon Safe projects on campus! Last year we completed the rain gardens in the front parking lots at MHCC (parking lots E, F, G, and H).
Moving to the next phase of the Salmon Safe project, partners are able to address a key infrastructure concern for the college. During peak storm events, a river flows on the road past the Fisheries building. This steady stream of stormwater erodes the foundation of the maintenance shop on the edge of Beaver Creek, polluting the habitat for the endangered salmon that live there.
Our solution is to remove a small amount of pavement in parking lots M, N, and P to infiltrate stormwater before it flows into the drains and to the creek. To infiltrate additional runoff, a 200-foot long rain garden (or "swale") will be installed parallel to Stark Street between the sidewalk and the college. Construction is anticipated this summer, starting in June or July 2020.
Returning funders, East Multnomah Soil and Water Conservation District, as well as the City of Gresham, will fund the entirety of the project with no charge to the college.
When classes resume in person again, the Sandy River Watershed Council will provide opportunities for student and community involvement, including volunteer days to plant native shrubs and plants where pavement was removed. Stay tuned, and thank you for your support!
MHCC Getting Salmon Safer
Mt. Hood Community College, the Sandy River Watershed Council and other partners are preparing to complete planned parking lot improvements as part of the Salmon Safe initiative to enhance water quality and habitat on the College’s Gresham campus.
An important goal of the Salmon Safe projects is to include the local community as much as possible. To date the SRWC has reached over 3,000 community members through in person outreach:
- Tabling at the MHCC Saturday market and campus events
- MHCC class presentations
- Volunteer work parties
In addition, the SRWC reaches much of the local community through traditional and digital outreach channels (ex: mailers, flyers, email, social media, and website)
30 different MHCC classes have participated in the project so far in various ways including: developing signage, conducting spawning surveys, and evaluating the project design. In the future students will be able to analyze water quality data from before and after project completion.
Related Culvert Replacement Projects
Other efforts happening around campus to improve conditions for salmon include the replacement of fish passage inhibiting culverts near campus. Culverts allow streams to flow under a road, but often cause erosion problems that make it difficult for fish to get upstream.
- In 2017, Multnomah County replaced the culvert on Beaver Creek at Stark St.
- In 2018, the City of Gresham replaced the culvert on Kelly Creek at Kane Dr. that had blown out during a record breaking 100-year storm December 2015.
- In 2019, Multnomah County will replace the culvert at the south end of campus on Beaver Creek under Cochran Rd.
