Document Description
The San Juan Creek Pipeline Repair/Protection Project temporarily impacts 0.27 acres of streambed within the San Juan Creek. This project is the second phase of repair activities to pipelines that cross San Juan Creek that were exposed and/or damaged as a result of the 2005 floods. Impacts to the stream channel include the following activities: a) The vertical installation of sheet piles within San Juan Creek on either side of the 48 inch SCP, jet groutting around the concrete-encased pipeline, and replacing the streambed materials to existing grade with earthen material; b) Repair/protection activities will occur within a 30 foot temporary impact zone (15 ft on either side of the existing pipeline); c) The location of repairs for the SCP, staging areas, and existing tractor path established during the first phase of repair activities will be reutilized for this phase; d) Repair and protection activities are anticipated to take approx four weeks; e) Temporary impacts to 0.27 acre of streambed will be restored to pre-construction contours and reseeded with appropriate native wetland vegetation.
