Marina Del Rey, CA

Beneficial Uses: Berm Creation, Shore Protection
Lead Agency: GEOTEC Associates, Inc. (Vicksburg, Mississippi), Los Angeles District, TC Mirafi Corporation, Geocontainer Group (Pendergrass, Georgia)
Placement Date(s): 1990's
Location: Marina Del Rey, California
Placement Method: Test demonstrations using sandy dredged material to fill geocontainers. Filled geocontainers were placed in water depths up to 70 feet using split hull bottom dump barges.
Substrate Type: Sandy dredged material with lead, zinc, and copper contaminants used as geocontainer fill material.
Project Size: 44 geocontainers, each containing an average of 1300 cubic yards of dredged material.
Project Costs: Contaminated material can be removed from the system for prices ranging from $16 to $79 per cubic yard.
Monitoring: Conclusions of these tests are: (1) geocontainers cannot be overfilled or they will fail; (2) fabric strength is of critical importance; (3) hopper barges must be clean and in good repair to deploy correctly; and (4) bulking factors of the material is of critical importance to successful deployment of tubes.
Comments: Field tests were conducted at Marina Del Rey to study the feasibility of filling geocontainers with dredged material. The tubes were lined with non-woven polyester geotextile that kept the material contaminated with lead, zinc, and copper from escaping. The geocontainers were filled and dumped into an approved underwater area out of harm's way.
