Emergency Storm Water Compliance
Emergency Response BMP Services, California
JJ&A was brought onto these projects due to our experience, technical expertise, responsiveness, practical can-do approach, and relationships with the regulatory community. We handled the many challenges that these emergency response projects faced including: multiple impacted locations, many stakeholders (municipalities, utility districts, Counties, regulatory agencies, and private landowners), steep terrain with highly erodible soil, and limited timeframes for completing the work.
Butte Fire Emergency Response Watershed Restoration, Amador County, CA
JJ&A provided storm water quality services for the Butte Fire Emergency Response Watershed Restoration project in Amador County, California. The fire burned 70,868 acres and destroyed 475 residences and 343 outbuildings. Over 40 separate areas required stabilization including laydown yards, work areas, and access roads and required coordination of a multi-disciplinary teams that included storm water and water quality experts, land planners, vegetation managers, restoration contractors, landowners as well as close coordination with regulatory agencies.
JJ&A developed an approach that provided a strategy for mitigating water quality impacts during the restoration project. The approach was to identify high risk areas and prioritize restoration activities based on risk level and location. The highest risk areas were located: (a) near waterbodies, natural drainages, or sensitive habitats, (b) on steep terrain, and (c) had potential impacts to homeowners. Multiple investigation teams were deployed to identify all areas requiring restoration. Appropriate best management practices (BMPs) were then determined for the areas requiring stabilization and restoration. Weekly coordination teleconferences were conducted with the response team to coordinate activities and to properly sequence the restoration/cleanup work to minimize conflicting operations, rework and inefficiencies.
NAPA/SONOMA FIRE COMPLEX EMERGENCY RESPONSE
JJ&A was contracted to provide storm water quality assessment and BMP implementation services for the Atlas, Nuns, and Tubbs Emergency Response Watershed Restoration project in Napa, Sonoma, and Solano Counties. The fires burned over 240,000 acres and an estimated 8,900 structures. Over 175 separate areas required stabilization following PG&E’s repair to transmission and distribution assets including laydown yards, work areas, and access roads.
Due to the size of the fires, the challenging terrain, and the limited timeframe before winter rains began, JJ&A developed an approach that identified high risk areas and prioritized restoration activities based on risk level and location. A separate investigation team for each fire was deployed to identify all areas requiring restoration at each of the fires. Teams utilized UAV (drones) and GPS to map, locate, and track all sites requiring restoration so that an efficient plan for implementing BMPs could be developed, focusing on the high risk areas. A database was prepared to track each location that was evaluated with KMZ files imbedded into the database for each location; this database was provided to the EFS team to track status and evaluation for the presence of a damaged transformer or other potentially hazardous cleanup. Once the initial assessment was completed, three BMP implementation crews, each managed by a QSP were deployed to begin restoration work. Much of the work focused on re-contouring temporary access routes utilizing heavy equipment, constructing structural BMPs, installing bio-degradable temporary BMPs, and hydroseeding where applicable. Our field team coordinated closely with vegetation management crews to ensure that native materials (wood chips and mulch generated from the post-fire vegetation clearing) were utilized to stabilize disturbed areas. Daily teleconferences were conducted with the response team, other contractors, and EFS to coordinate activities and to properly sequence the restoration/cleanup work to minimize conflicting operations, rework and inefficiencies.
