Organic Soil Erosion Control/Prevention Program (OSECP2)
 

Environmental Concepts & Designs (EC&D) has developed an Organic Soil Erosion Control/Prevention Program (OSECP2) that utilizes compost, mulch and compost/mulch blends in Best Management Practices (BMP's).

Organic Best Management Practices (BMP's)

Organic Filter Berm (OFB): Water permeable triangular shaped row of compost/mulch blend used to control erosion by removing and containing sediments & contaminants from storm water moving through the compost "filter" and off-site.


Initial Installation


After 3 Inch Rain
Note: Sediment Still Securely Contained

Contained Organic Filter Berm (COFB): Compost/Mulch blends contained in continuous tubular mesh material of various diameters providing a storm water filter and sediment barrier; performs like (OFB).



COFB Installation





Protects on Impervious Surfaces



Organic Erosion Control (ERC) Blanket: Surface application of compost/mulch blends to protect areas with erosive potential. High quality compost (containing a high quantity of organic matter) acts as a "soil glue" by interfacing with the soil and holding particles in place.

COFB Behind the Curb: A sediment barrier consisting of compost/mulch blends contained in continuous tubular mesh material to protect roadways and storm water drains from sediments.

Organic Check Dams: Constructed across a drainage swale or channel to disperse the energy, slow the speed of concentrated flows, and contain moving sediments.

Performance After Rain Event



Organic Inlet Sediment Barriers:  COFB or OFB placed either in front of or around a storm drain inlet to reduce and/or prevent sediments from
entering storm drain.

Organic Seeding: Mixture of compost & seed applied to a soil surface


Organic Over Seeding: A uniform layer of compost & seed applied to an established, but usually declining turf area.


Research Has Shown That Adding Compost to Soils Through       
Organic Seeding and Organic Over-Seeding:


By incorporating compost into soil for establishment of lawns and landscape plantings, water used for irrigation and the potential of underground water contamination is drastically reduced. (Composting Vermont)

Compost retains and slowly releases moisture and encourages deeper rooting, thus reducing the need for watering. (King County Department of Natural Resources. 1999)

Compost-amended turf increases the storm water retention capacity of a lawn and reduces soil erosion.
(City of Raymond Public Works)

Compost can increase infiltration up to 125% once incorporated into the soil. (Demars, Long. 1998)


Organic Best Management Practices (BMPs):

Organic BMPs

Dusting


Conventional BMPs

1-1/2 " Sediment

Subdivision Storm Water Collection Line: 50 acre drainage site was 90% protected by Organic BMPs and 10% protected by conventional BMPs. Note sediment difference in collection lines.


Research Has Shown That BMPs:

Are More Efficient at Controlling Erosion.  Studies have shown that 10 times more sediment is released from silt fence and hay bales than from Organic Filter Berms. (Demars, Long. 2000)

An Organic Filter Berm can absorb a volume of water equal to approximately 30% of the volume of the berm.
(Caine,2001)

Organic Erosion Control Blankets produce significantly less run-off during a high intensity rain fall (4 in/hr) and due to water absorbing capacity of compost. Run-off from Organic ERC Blanket took an average of 30- 60 minutes to initiate after rainfall began; while top soil initiated run-off with in 5- 8 minutes. (Glanville, et.al,2003)

Compost Application Reduced Soil Loss by 86% compared to bare soils. Sediments reaching nearby surface waters decreased by 99% when compared to silt fence, at 40%. (Demars, Long 1998)

Some Of The OSECP2 Components We Offer:

Workshops and Presentations to educate builders, contractors, etc. about the benefits of Organic BMP's. Presentations include text and digital photos illustrating Organic BMP instillation techniques and costs.

Manuals, Design Drawings & Specifications, CD-ROM's
that provide drawings, photos and concise informative text.

Training of Installers (pneumatic blower truck operators) to develop or procure the correct compost/mulch blends to ensure efficient erosion controls are learned while achieving the highest level of performance from OSECP2. Perform infield applications and demonstrations to ensure proper installation. Assisting clients in educating and integrating OSECP2 into your local construction and regulatory communities.
