None were impacted. ●All sensitive biological resources were monitored and no adverse impacts occurred. Weather Conditions Conditions:Mostly sunny in the morning, with some clouds moving in during the afternoon Temperature:69 F Humidity:66%Wind:SW 4 mph Cloud Cover %:20 Temperature:75 F Humidity:48%Wind:SW 10 mph Cloud Cover %:25 Endemic Environmental Services Construction Activity Name of Contractors Performing Work:DD Systems Relevant Person(s) in charge of construction:Danny Start Time:1100 End Time:1600 Is project work activity compliant?Yes Construction Activity Notes/Equipment Used:Hand tools,Mini excavator, 249D Skid steer -The crew added wooden stakes along the PVC pipe to keep the pipeline in place and out of the trail (Figure 1).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. -Trail widening progress continued Westward using a mini-excavator and skid steer to remove vegetation and grade the edges of the trail (Figure 2).The skid steer was also used to smooth the trail and compact the soil (Figure 3). -Large rocks were removed from the center of the trail.The mini-excavator dug them up and deposited them on the side of the trail (Figure 4). -Crew tested the water hookups and pipeline along the trail. 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:1100, 1240 GPS Location of Listed Species (if applicable): 34.003999 °N, 117.794354 °W; 34.003042 °N, 117.801729 °W Description of Listed Location:Both observations occurred in disturbed coastal sage scrub habitat. Bio-monitor Notes:The first was heard downslope of the staging area and left quickly as the crew began working.The second was heard near the bottom of the south trail loop,to the west of the site,and left quickly as the skid steer and mini-excavator work approached. 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? Species Common Name/ Scientific Name: Age/Class: Gender: Did take occur due to project work activity? GPS Location of Take (if applicable): Description Location of Take: Bio-monitor Notes Endemic Environmental Services Nest Findings Were there any nests observed on or near project site?No If yes, then: Were nests active or non-active? Nest(s): Species (If identifiable): Time Observed:Nesting Status: GPS Point of Nest: Location Description of Nest: Biomonitor Notes: Other Nest Notes: Endemic Environmental Services Nest Removal Section Were there any Nests removed?No If yes, then: Was the MBTA Nest active or non-active? Time of Nest Removal? 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, California Buckwheat. What type of impact occurred?Removal via excavator. Square Footage of Impacted Area:Approximately 65.6 sq ft, or 0.002 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.Another small area of vegetation was permanently impacted while the skid steer leveled and graded the area around a buried water PVC pipeline. Endemic Environmental Services Non-Listed Species Section Were there any non-listed species observed?Yes If yes, then: Species Common/ Scientific Name: American crow (Corvus brachyrhynchos), California Quail (Callipepla californica), Turkey Vulture (Cathartes aura),Mourning Dove (Zenaida macroura),Common raven (Corvus corax),Red-tailed hawk (Buteo jamaicensis),House Finch (Haemorhous mexicanus),California Towhee (Melozone crissalis), Anna’s hummingbird (Calypte anna), California Scrub-Jay (Aphelocoma californica), Cassin’s kingbird (Tyrannus vociferans), Bushtit (Psaltriparus minimus),Nuttall’s woodpecker (Dryobates nuttallii), Western Meadowlark (Sturnella neglecta), Ruby-Crowned Kinglet (Regulus calendula), California ground squirrel (Otospermophilus beecheyi), Tree Swallow (Tachycineta bicolor), Northern Mockingbird (Mimus polyglottos).
