Plant inspections were conducted on November 2nd, 3rd and 5th and included inspecting delivered plants and verifying placement of tree species. On November 3rd, an irrigation mainline pressure check for the mainline servicing the upstream mitigation areas (east of the waterfall) was conducted. The extent of the mainline for this stretch is above grade. Dudek met with Green Horizon representative Antonio for all coordination. Comments and recommendations are included below. Figure 1 contains photos from the inspections. 'Plant Inspections: The November 2nd inspection consisted of verifying tree planting locations for mitigation areas downstream (west) of the waterfall. Dudek made minor adjustment to pin flagged plant locations, primarily moving willows (Arroyo lasiolepis, A. gooddingn) to wetter locations and sycamores (Plafanus racemosa) and Mexican elderberry (Sambucus mexicanus) to drier locations. Recommendations were made to install additionalplantsin the upstream quarry area (enhancement areas). 2. The November 3rd inspection consisted of checking in tree container plants and irrigation coverage check (discussed below). All plants delivered appeared to be healthy and adequately rooted in their container but not root bound. All containers appeared free from weeds and non-beneficial insects. During the morning visit, trees were placed at the location of planting. Dudek made minor adjustment to proposed installation locations. At the afternoon visit, Dudek recommended that all basins were hand watered-in and for basins to be created around each container tree installed (per the 'plan detail and specifications). The following plants were inspected: Platanus racemosa (1 gal.) —55 Salix gooddingii (1 gal.) - 100 Salix lasiolepis (1 gal.) - 306 Sambucus mexicanus (1 gal.) —65 3. The November 5th inspection consisted of checking in shrub container plants and assisting the contractor in placement. All plants delivered appeared to be healthy and adequately rooted in their container but not root bound. All containers appeared free from weeds and non-beneficial insects. During the morning visit trees were placed at the location of planting. Dudek made recommendations for placing particular weltand plant, based on site hydrology and tree placement. The following plants were inspected: a. Anemopsis califomica (1 gal.) - 1500 DUDE K 605 Third Street Encinitas, California 92024 T800.450;I8l8 F 760.632.0164 Eleochans macrostachya (1 gal.) - 298 Juncus acutus (1 gal.) —298 - A. Rosa californica (1 gal.) -150 e. Rubus ursinus (1 .-gal.) - 135 Irrigation Inspection: SITE OBSERVATION 'REPORT 4. On November 3rd, Dudek conducted the mainline pressure check for the on-grade section of the pressure mainline east (upstream) of the waterfall. Dudek verified the mainline was pressured to a minimum of 150 psi during the morning inspection. The inspection was at approximately 11:00 AM. Dudek returned to the site at approximately 2:55 PM and confirmed that the pressure was maintained above 150 PSI.
