Location: Los Angeles, CA | Client: City of LA | Contact: Confidential | Contract Value: $15,000
Key Outcomes
Project Background
OMS Group, LLC (OMS) were engaged by our client to provide a stormwater pollution prevention plan to address agency concerns related to construction site staging and other soil disturbing activities for a planned river channel restoration effort in the Los Angeles River.
Scope
OMS staff collaborated with the construction contractor to modify planned staging areas so that a single ingress and egress point would be used for all equipment and materials. We developed a stabilized exit point to minimize potential for track-out of construction soils and also provided value engineering services to modify construction means and methods to utilize a chute to transport native river rock from a borrow pile at the top of the streambank down to the river channel. This modification significantly reduced the amount of erosion potential related to the planned use of 30 to 40 ton front end loaders to transport materials down the stream bank. OMS staff also utilized BMP’s and standardized solutions to address potential stormwater concerns.
- Mitigated stormwater pollution potential to protected waters of the U.S.
- Complied with permit conditions
- Reduced cost of implementation through minimization of disturbed soil
