None were impacted. ●All sensitive biological resources were monitored and no adverse impacts occurred. Weather Conditions Conditions:Sunny in the morning, with clouds moving in during the afternoon Temperature:53 Humidity:43%Wind:NE 4 mph Cloud Cover %:15 Temperature:76 Humidity:33%Wind:SW 8 mph Cloud Cover %:85 Endemic Environmental Services Construction Activity Name of Contractors Performing Work:DD Systems Relevant Person(s) in charge of construction:Danny Start Time:0700 End Time:1600 Is project work activity compliant?Yes Construction Activity Notes/Equipment Used:Mini excavator,hand tools, skid steer -The crew laid PVC pipe to create access to water for construction activities.In areas where it intersected with a trail,they used an excavator to trench the path,and after laying the PVC,they backfilled using the skid steer (Figure 1).Where possible,they laid the PVC on top of the ground off of the main trail (Figure 2). -Trail widening progress continued Westward using a mini excavator to remove vegetation from the edges of the trail (Figure 3).After removing vegetation it was also used to smooth the trail and compact the soil (Figure 4). -Large rocks were removed from the center of the trail.The excavator dug them up and deposited them on the side of the trail (Figure 5). Endemic Environmental Services Biological Resource Findings Were there any listed species observed on or near site?Yes If yes, then: Was listed species impacted due to work?No Species Common/ Scientific Name:Coastal california gnatcatcher (Polioptila californica california) Time of Observed Listed Species:0730, 1030, 1400 GPS Location of Listed Species (if applicable): 34.003456 °N, 117.798304 °W; 34.003364 °N, 117.798856 °W; 34.003388 °N, 117.802277 °W Description of Listed Location:All three observations occurred in disturbed coastal sage scrub habitat. Bio-monitor Notes:The first was a female foraging in buckwheat (Eriogonum fasciculatum),the second was a male calling and jumping in between buckwheat bushes,and the third was heard downslope of the trail and left quickly. Endemic Environmental Services Species Take Section Was there a take of any listed or regulated species?No If yes, then: What type of take occurred?

Why was the nest removed?: Species Scientific/ Common Name: GPS Location of Removed Nest (If applicable): Bio-monitor Notes: Endemic Environmental Services Wetlands and Jurisdictional Waters of the U.S. Are Wetlands or Jurisdictional Waters of the United States Present?No If yes, then: What Watershed? Were Wetlands or Jurisdictional Waters of the United States impacted by project work activity?No What type of impact occurred? Bio-monitor Notes: Endemic Environmental Services Vegetation Impact Section Was vegetation impacted by project work activity?Yes If yes, then: Habitat Type:Disturbed California sagebrush and Prickly Pear Shrub Type of Vegetation Impacted:California sagebrush (Artemisia californica),mustard sp.,fiddleneck sp.,black sage, and white sage. What type of impact occurred?Removal via excavator. Square Footage of Impacted Area:842.8 sq ft, or 0.019 acres Bio-monitor Notes:Thin sections of native sage scrub were removed by the excavator from the edges of the trail in order to widen it.A small area of vegetation was also permanently impacted by moving removed boulders onto the sides of the trail. Endemic Environmental Services Non-Listed Species Section Were there any non-listed species observed?Yes If yes, then: Species Common/ Scientific Name: Northern flicker (Colaptes auratus),Wrentit (Chamaea fasciata),American crow (Corvus brachyrhynchos), Mourning dove (Zenaida macroura),Common raven (Corvus corax),Red-tailed hawk (Buteo jamaicensis),House finch (Haemorhous mexicanus),Cooper’s hawk (Accipiter cooperii), California thrasher (Toxostoma redivivum), California quail (Callipepla californica), California towhee (Melozone crissalis), Anna’s hummingbird (Calypte anna), California scrub-jay (Aphelocoma californica),Turkey vulture (Cathartes aura),Cassin’s kingbird (Tyrannus vociferans), Bushtit (Psaltriparus minimus),Nuttall’s woodpecker (Dryobates nuttallii), acorn woodpecker (Melanerpes formicivorus), western meadowlark (Sturnella neglecta),ruby-crowned kinglet (Regulus calendula), lesser goldfinch (Spinus psaltria), California ground squirrel (Otospermophilus becheeyi) Bio-monitor Notes:N/A Endemic Environmental Services Photos Section Figure 1.PVC pipe installation in trench before backfilling took place.
