| Growing conditions during inspection | ||||
| Temperature | Soil moisture | |||
| Sunny or cloudy | ||||
| Date of last rainfall | ||||
| Have action items from last inspection been addressed? | ||||
| VEGETATION | ||||
| Current condition compared to project requirements | ||||
| Item inspected | Project requirement | Current condition | Notes | Action needed and deadline |
| Percent cover of healthy acceptable plant species | ||||
| Diversity of acceptable species | ||||
| Percent cover of weeds - list species in notes | ||||
| Dominant species – note all species 5% cover or more | ||||
| Species scientific name | Percent cover | Notes | ||
| Signs of plant stress: | ||||
| Sign of plant stress observed | Species in which it was observed | % cover of plants showing signs of stressr | Notes: potential cause of stress, other observations (e.g. radiation from adjacent glass curtain windows, inadequate nutrient or water levels, heat, wind, pests, disease) | |
| Signs of plant stress: | Yes | No | ||
| Is it necessary to cut dried vegetation or remove thatch? I.e. is dried vegetation or thatch so thick that it is negatively affecting roof vegetation health? | ||||
| Additional vegetation notes or action items: | ||||
| GROWING MEDIUM AND DRAINAGE | ||||
| Item inspected | Y/N | Notes – e.g. what appears to be causing problems? Description of problems | Action Needed and deadline | |
| Gullies or other signs of erosion or sedimentation observed? | ||||
| Evidence of wind scour? | ||||
| Ponding or soggy spots observed? | ||||
| Clogged, misaligned, or ineffective drains | ||||
| Draw areas where problems were observed on attached as-built plan sheet | ||||
| Media texture and thickness observed: | ||||
| Media texture and thickness observed: | ||||
| Additional soil needed? | ||||
| Soil test performed for nutrient content in past 12 months? | Yes | No | ||
| (see Task 6 for more information on green roof soil tests) | ||||
| If yes, attach results, if not, perform soil test | ||||
| Based on soil test results and condition of vegetation, is fertilization needed? | Yes | No | ||
| ROOT DEVELOPMENT | ||||
| At representative locations, excavate to the depth of the separation fabric and observe the root-zone conditions: | ||||
|
||||
| Show representative locations and observations on as-built plan sheet and attach to this checklist | ||||
| IRRIGATION | ||||
| Do any broken drip or supply lines, or any other irrigation components need repair? | ||||
| Is there evidence of uneven irrigation levels, such as desiccated media or marshy conditions? If so, note on as-built plan. | ||||
| Does irrigation regime need to be adjusted? | ||||
