Let CSLRCD Help You Control and Prevent Erosion This Winter

The rainy season is fast approaching. What may now be a small erosion issue has the potential to become a large and expensive problem. If left untreated, erosion can result in detrimental impacts to both land productivity and natural resources. 

During and immediately following the 2016-2017 rainy season, CSLRCD fielded countless phone calls and coordinated numerous site visits as a reaction to significant erosion triggered by last year's rain. We encourage landowners and managers to be progressive and prescriptive in advance of our pending rainy winter this year.

Start by contacting our office -- we can brainstorm about how to prepare for rain and assist with a cost-effective plan for "winterization." We also can identify whether resources (e.g., financial, people power, materials) are available to  help reduce and/or eliminate erosion and instability before another rainy seaon arrives.

Check with us for additional references, recommendations, workshops, education opportunities, or to schedule a site visit. For more information, call CSLRCD at (805) 772-4391. 

 

 

 

 

 

 

Oso Flaco Watershed Projects

Blackberry/Bioreactor Crop Ripens

The fruits of our labor have arrived! The first blackberry crop is ripening nicely as the bioreactor continues to remove pounds of nitrates from the Oso Flaco watershed. The berries will be harvested and analyzed for weight, yield and sugar content. That data will be compared against berries harvested in a nearby commercial growing operation to determine if the berries grown on the bioreactor are competitive with commerical berries.

The project, funded by CDFA and supported by State Parks and SWRCB, demonstrates the versatility and efficacy of woodchip bioreactors, proving that on-farm water quality can be improved without loosing arable land to a treatment structure. Demonstrations and field tours are planned for later in 2017.

Oso Flaco Lake Remediation Planning Underway

The CSLRCD and State Parks are working on a planning and assessment grant for Oso Flaco Lake, which will eventually be used to indicate how best to treat the contaminated sediment in both Oso Flaco and Little Oso Flaco lakes.

Oso Flaco Lake has the highest levels of DDT contaminated sediments in California lakes. The work completed to date includes an aerial survey of the lake, sampling and chemical analysis of sediment cores, and the development of an Alternatives and Constraints report based on the results of the sediment analysis. Preliminary analysis of the cores verifies high DDT concentrations in sediment as deep as 4.5 feet below the lake bed.

The Alternatives and Constraints report outlines four remediation plans: 1) dredging both lakes to remove contaminated sediment, 2) capping the contaminated sediment under a layer of sand or fine material, 3) taking no action, or 3) a hybrid treatment of dredging hot spots and monitoring changes to ecosystem health.

All remediation plans will be assessed for benefits, impacts and feasibility. Based on these findings, one plan will be chosen in 2018 for implementation.

 

Time to Toast! Arroyo Grande Conservation Easement Is a Reality

Construction of an Ag Pond0.jpgAfter many folks working for years to acquire a conservation easement that would allow a floodplain and stream restoration project to be implemented, the CSLRCD finally closed escrow on the easement on May 26, 2017. Although itis of great significance, the purchase of this easement is only one component of the planned floodplain and stream restoration project along Tally Ho Creek in the City of Arroyo Grande.

The easement will allow the construction of a stormwater detention facility capable of holding thousands of tons of sandy sediment that would otherwise impact lower Arroyo Grande Creek, and temporarily hold 20 or more acre-­‐‑feet (6,517,029 gallons) of water during storm events. This project will also improve riparian habitat, permanently preserve 12.5 acres of open space and improve hydrologic function along lower Tally Ho Creek. The project will positively affect the main stem of Arroyo Grande Creek and the flood control channel (Zone 1/1A) by reducing sediment loads and flood waters, in turn reducing associated costs of channel maintenance and flood damage.

Restoration Planned for Los Osos Property 

CSLRCD staff and other project partners toured a Los Osos property in February to discuss restoration plans. This property was purchased by CSLRCD in 2015 with funding from CA Coastal Conservancy and U.S. Fish and Wildlife Service.

District Engineer William Arkfeld, PE, brings more than 31 years of environmental and civil engineering experience to the CSLRCD. A graduate of Humboldt State University with a degree in Environmental Resources Engineering, he has been a licensed Civil Engineer for more than 27 years. His strong interest in agriculture is a direct result of childhood experiences on relatives' farms in Iowa.

Environmental Resource Specialist Micaela Mellein graduated from Cal Poly San Luis Obispo with a degree in Animal Science and a minor in Rangeland Management. She has a background in livestock management, agriculture and irrigation.

Restoration Specialist I Alyssa Bucci came to CSLRCD in 2016 as a member of the Watershed Stewards Program, an AmeriCorps program. She was mentored by our staff and worked on various projects from bank stabilization, map making and restoration to giving a presentation to the County Board of Supervisors. When her 10-month assignment ended, we were fortunate to hire her for the Oceano Dunes restoration/dust control project.

Board Member Jessica Crutchfield is an environmental attorney who assists property owners, lenders and loan servicers with environmental due diligence, risk management and compliance. She provides pragmatic solutions catered to her clients' needs. She has written about the regulation of dust in rural areas and presented on the topic of urban agriculture.
