Hillside Natural Area (HNA) Fire Road Repairs

The project will repair the HNA fire road at six locations that were significantly damaged during storms in February 2017 using FEMA and Cal OES funding. Heavy rains, flooding and high-velocity winds caused widespread damage throughout the State of California. These conditions existed in the federally-declared County of Contra Costa, including in the City of El Cerrito, which maintains the fire access roads and recreational trails in HNA. This 102.5-acre undeveloped open space includes extensive native vegetation, an oak woodland, riparian environments, Eucalyptus groves, and the majority of the City’s urban tree canopy; it is surrounded by residential neighborhoods and is in a designated Very High Fire Hazard Severity Zone.

Sites 1 through 5 fire road repairs generally includes clearing and grubbing of the fire roads, scarifying the road and edges, minor re-grading to fill washouts and re-contour cross slopes, restoring the road profile and cross-section with soils on site, moisture conditioning, recompacting existing soils, installing earthen water bars, erosion and dust control, and other related work. Site 6 repair of a damaged wooden retaining wall and washed out embankment and road is more extensive and is currently being evaluated by FEMA.

Construction is anticipated to start in late Spring 2019.
