This area was in the drip line of an oak tree Danny was asked to skip the area until further information was gathered ●All sensitive biological resources were monitored and no adverse impacts occurred. ●There was no secondary containment under the staged equipment: skid steer, mini excavator. Weather Conditions Conditions:Overcast Temperature:53 Humidity:93%Wind:NE 1mph Cloud Cover %:100 Temperature:76 Humidity:56%Wind:SW 9 mph Cloud Cover %:0 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 and hand tools -A Mini excavator was used for digging, spreading material and moving rocks. 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:California gnatcatcher (Polioptila californica) Time of Observed Listed Species:1145 GPS Location of Listed Species (if applicable):11S 426228, 3762751 Description of Listed Location:Disturbed California Sagebrush Bio-monitor Notes:Right when the mini excavator parked for lunch the California gnatcatcher flew near the work area,landed on a sagebrush (less than 100ft away),called,then continued downslope out of view.The observation lasted less than a minute. 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:Black Sage (Salvia mellifera),mustard sp.,fiddleneck sp.,California sagebrush and white sage. What type of impact occurred?Removal.They cleared and grubbed before excavation.Also temporary impacts from stockpiling material on plants. Square Footage of Impacted Area:400 sq ft removed. Bio-monitor Notes:The workers did vegetation removal with shovels at a pad for another shelter and bench. This was 20 ft x 20 ft. There is a stockpile which is 16ft wide and 19ft long =304 sq ft temporary disturbance.It is covering a few black sage plants and dried mustard. This was considered a temporary impact since the roots remained. 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),American robin (Trudus migratorius),Say’s phoebe (Sayornis saya),Black phoebe (Sayornis nigricans),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), Northern mockingbird (Mimus polyglottos), California towhee (Melozone crissalis),Spotted towhee (Pipilo maculatus), Anna’s hummingbird (Calypte anna), California scrub-jay (Aphelocoma californica), Turkey vulture (Cathartes aura),Cedar waxwing (Bombycilla cedrorum),Cassin’s kingbird (Tyrannus vociferans), Bewick’s wren (Thryomanes bewickii),Blue-gray gnatcatcher (Polioptila caerulea), Bushtit (Psaltriparus minimus),Nuttall’s woodpecker (Dryobates nuttallii), Side-blotched lizard (Uta stansburiana),Tarantula spider (Aphonopelma sp.) Bio-monitor Notes:The mini excavator was staged further down the trail at the first gabion excavation location. There was no secondary containment under the staged equipment: skid steer, mini excavator, and cherry picker. The mini excavator resumed excavation work along the slope leading toward the stairs for the southern loop trail. I asked the operator about the work limits because of the stockpile he was creating.He responded that some of the spoils were used to level out the trail,some are meant for backfilling behind the gabion and according to the operator the excess material can be spread out since it won’t be exported.So the stockpile on the vegetation would be a temporary impact to vegetation.And there doesn’t appear to be a work limit.However,the operator mentioned 9 feet from the pink feather (5 ft on one side and 4 on the other). The workers spray painted the cut area by the stairs. A portable toilet was dropped off at the primary staging area near the homes.There is no secondary containment. Trail still walked by pedestrians even with the trail closure signs. At 1330 we approached the first oak tree.According to the Figure 4 map this is a no work area.There are several additional no work areas which coincide with oak trees.I stopped the operator before he reached the oak tree.He called Danny and I contacted PM Alex Eagleton of Endemic to make sure this was a no disturbance Endemic Environmental Services area.Alex agreed and Raul Sr.the operator was told to skip the spot.His blue prints show a non disturbance area too. I showed the operator a orange sprayed line that corresponded with another no disturbance area. Excavation resumed at the junction of the south loop trail and the trail to the community center.This is where the cacti area begins.There is supposed to be a shade shelter,bench,and stairs installed here.The workers began vegetation clearing an area 20 ft x 20 ft of Cacti Prickly Pear Shrub consisting of disturbed California sagebrush, white sage and mustard. They started the layout for the steps. I mentioned reminders about how smoking is usually not allowed near sensitive habitats and that fueling typically requires containment.
