The Sediment Memo documents what information is known about sediment in the four tributaries of Clear Creek- Canyon, Clear, Swan, and Squally Creeks. It also summarizes what is known about sediment in the Puyallup River, based on a presentation by Kris Jaeger of USGS on November 2, 2016.
The agricultural community in the area requested more information about sediment, in order to increase understanding of current and future sediment regimes, how sediment affects flooding and drainage, and how an earthen berm may impact sedimentation. This memo is based on several conversations with experts, published data, and a presentation and discussion from the 4th TAG meeting.
The fourth meeting of the Technical Advisory Group (TAG) for the Farming in the Floodplain Project (FFP) was held on November 2, 2016 at the Puyallup Library. Kris Jaeger from USGS presented on sediment from the Puyallup, and Spencer Easton from ESA (our technical contractor) presented on sediment from the Clear Creek tributaries. There was also a discussion of the Drainage Inventory Preliminary Findings Memo. A full report of the meeting can be found here: TAG 4 Report
Our next TAG meeting will be in early February. We will discuss conservation easements, the Flood Risk memo that ESA is currently drafting, and hear from Cynthia Krass, the Executive Director of the Snoqualmie Valley Watershed Improvement District, who will discuss the efforts of farmers in the valley to organize around drainage and water rights.
The initial fieldwork for the Drainage Inventory was completed by ESA in September and October 2016. ESA will be analyzing the data and findings and conducting more field work after an intensive rainfall. In March, we will distribute a draft of the final Memo for review.
During the last 9 months, we have heard from many agricultural landowners, farmers, and growers in the area through one-on-one discussions, Technical Advisory Group meetings, and informal conversations. This research resulted in the Existing Conditions Report, and informed the research and work plan for the next 12 months, ending in June 2017.
This work plan was the result of many discussions with farmers and growers in the Clear Creek area. Issues important to the agricultural community, including some expressed by the Clear Creek Farmer’s Collective, were critical in identifying and prioritizing how to proceed with research and on-the-ground work in the coming year. We are immensely grateful to farmers for their time spent in reviewing both the Existing Conditions Report and several previous versions of the work plan- this helps us ensure that work completed under this Floodplains by Design grant directly supports the long-term agricultural viability of the Clear Creek area.
The Farming in the Floodplain Project works hard to be flexible and responsive to the needs of the agricultural community, and respond to new challenges and opportunities as they arise. With that in mind the Research Plan and accompanying Timeline are subject to change. As always, contact us if you have any comments or questions.
In late August, Washington Conservation Corps crew members and the community volunteers, led by Loren Paschich, completed work clearing out reed canarygrass from Canyon Creek (upstream of Clear Creek) from 52nd about 1600 feet northwest. Loren’s team spent most of the summer clearing blackberry and thick grass along the drainage easement, which allowed the WCC crews to efficiently work within the creek. While the crew worked on the creek, Loren and his team also performed maintenance on Nancy’s Ditch, parts of South Ditch, and on the northwest portion of the creek.
Drainage District 10 is working on a maintenance plan for the coming year to build on these efforts. This month, the Farming in the Floodplain Project technical contractors, ESA, has a field crew performing a drainage inventory on Clear Creek, Canyon Creek, and the drainage ditches. Thank you to the many landowners who have assisted with access to the ditches!
On September 20th, the technical contractor, ESA, will have a field team in the area working on a drainage inventory. Work will continue through September 28th. This work is expected to help the agricultural community and Drainage District 10 in a number of ways, including:
Providing a more comprehensive understanding of how the drainage system (not just the parts owned by the drainage district) works;
Providing information that can help with planning of future maintenance activities and that could help fill out permits (though we will not provide permit-level survey data);
Will make recommendations for needed maintenance activities; and
Will provide a baseline for existing conditions so that the County’s proposed project and other future planning and project efforts can be appropriately evaluated for their impacts or improvements to drainage.
We will be reaching out to landowners in advance of this work to discuss any questions you might have and in some cases, request your permission to access the drainage ditches adjacent to your property.
A preliminary report will be made available in late Fall.
This week, the Washington Conservation Corps (WCC) crew members and local volunteers have begun work on Clear Creek along Pioneer Way, starting at 52nd street near Chief Leschi school. They will be working for approximately 12 days (Mondays-Thursdays) in August, including the weeks of August 8th and 15th. Their work is focusing on reed canarygrass removal to improve the flow and capacity of the creek/drainage ditch. Drainage District 10 Commissioners are coordinating with the crew to plan for longer term maintenance of the creek and are considering multiple options for long term solutions for invasive reed canarygrass.
The Farming in the Floodplain Project is able to provide funding for the WCC work through the Puyallup Floodplain Reconnections grant through the Department of Ecology’s Floodplains by Design program. We are excited to be able to support on-the-ground work towards the ongoing agricultural viability of this area. We continue to seek ways to work collaboratively with other stakeholders and interests to ensure that the importance of the agricultural community is recognized and supported, and welcome input on our work.
Loren Paschich has been an incredibly valuable leader in these efforts- he has assembled a team of volunteers and cleared an access path through blackberries and thick reed canarygcass along the ditch from Chief Leschi school northwest for over 1/4 mile. The volunteer team has been removing reed canary grass from the ditch from the northwest while the WCC crews work from 52nd street towards Loren’s team. Without Loren’s efforts, this work would take weeks longer and would not be nearly as effective. Please get in touch with him if you would like to help out for a day or two!
This report examines the current conditions that affect agriculture in the Clear Creek area and uses the context of “risk” to discuss what future actions might increase or decrease the risks that impact long-term agricultural viability.
This report is the result of many months of technical research, three Technical Advisory Group meetings (including local farmers and growers), and conversations with farmers and residents in the area. The report informs the workplan for Phase 2 (August 2016-June 2017) of the Farming in the Floodplain Project, which will explore specific risk factors in depth in order to inform recommendations on addressing risk and benefit to agriculture for projects in the area.
ESA (our technical contractor) has been hard at work on a lot of research related to agricultural viability in the Clear Creek area. As we all dig into understanding what information is available, and what information we need, we’ve unearthed a ton of data. ESA has compiled an interactive web map of relevant data from the Existing Conditions Report, allowing the user to view different layers and easily compare where current agricultural land is in relation to elevation, for example. This map will continue to be updated, and we hope it is a helpful resource for comparing the many maps that exist for the area.
Let us know if you have any ideas for additional data to add, or ways to make this map more helpful for you.
Invasive Species remediation and channel improvements
Washington Conservation Corps (WCC) Crew members will be performing drainage ditch maintenance in the Clear Creek area during the month of August. They will be focusing their efforts on reed canarygrass removal in the ditch along Clear Creek on the north side of Pioneer Way.
The WCC Crew (pictured above) will be working with Drainage District 10 and community members on these efforts. This work is being funded in part by the Farming in the Floodplain Project under the Puyallup River Floodplain Reconnection grant funded by Department of Ecology’s Floodplains by Design program. This work is the result of ongoing collaborative efforts between the Puyallup Tribe of Indians, Pierce County’s Surface Water Management, Pierce County’s Executive Office, PCC Farmland Trust, Drainage District 10, and the Clear Creek Farmer’s Collective.
Based on a trial on Thursday July 28, the crew estimates that this effort will take several weeks, and hopes to start work the week of August 8. Drainage District 10 will host a public meeting regarding this work later in the month, and may be seeking volunteer labor to support the WCC efforts.
