hoary bats and Hawaiian hawks, island wide-ranging species that will experience no adverse impacts due to mitigation through seasonal timing of vegetation removal and seasonal hawk surveys as needed, no rare, threatened or endangered species of fauna are known to exist on or near the property, and none would be affected by any project activities. Only very minor exterior lighting is planned, and it will be shielded and will consist of blue-deficient lighting such as filtered LED lights or amber LED lights, with a Correlated Color Temperature(CCT)of 2700 Kelvin. This will reduce the risk that transiting threatened or endangered seabirds may be attracted to and then disoriented by the lighting. 10. Have a substantial adverse effect on air or water quality or ambient noise levels. No substantial effects to air, water, or ambient noise would occur. Brief, temporary effects would occur during construction and would be mitigated. The context of the property's location, with no residences, parks, or other sensitive uses nearby, will help avoid noise impacts. Erosion and sedimentation impacts will be avoided by implementation of Best Management Practices during grading, which will occur in a very limited area. 11. Have a substantial adverse effect on or be likely to suffer damage by being located in an environmentally sensitive area such as a flood plain, tsunami zone, sea level rise exposure area, beach, erosion-prone area, geologically hazardous land, estuary, fresh water, or coastal waters. The proposed home site is not located in a flood zone nor would it affect one. In general, geologic conditions do not impose undue constraints on the proposed action, as volcanic hazard is low and the home will meet or exceed all seismic hazard standards. The house would be set back a minimum of 130 feet from the edge of the pali, and will not be affected directly by sea level rise or the slow retreat of shoreline cliffs. The project has adapted to climate change by accounting for the potential for larger storms, through minimizing hard surfaces that generate runoff and removing nearby tall invasive trees. The applicant understands that there are hazards associated with homes in this geologic setting and has made the decision that a residence is not imprudent to construct or inhabit. 12. Have a substantial adverse effect on scenic vistas and viewplanes, during day or night, identified in county or state plans or studies. No protected scenic views are located nearby or would be affected in any way. The proposed use is consistent with other single-family residential and farming uses in the area. It will be in area barely not visible from the shoreline and barely visible from the sea, and not at all visible from the nearest State highway or any other public road. Only very minor exterior lighting is planned, and it will be shielded and will consist of blue-deficient lighting such as filtered LED lights or amber LED lights, with a Correlated Color Temperature(CCT)of 2700 Kelvin. This will protect dark skies reduce the risk that the threatened or endangered seabirds that may be attracted to and then disoriented by the lighting. 13. Require substantial energy consumption or emit substantial greenhouse gases. Negligible amounts of energy input and greenhouse gas emission would be required for construction and occupation of the residence. The residence is designed as a single structure supporting efficient use of energy and materials and facilitating natural ventilation and lighting. The home will also have roof-mounted photovoltaic and solar water heating panels, reducing energy use and greenhouse gas emissions. Energy-efficient appliances will be used throughout the house. A design that accommodates natural ventilation and an insulated roof structure will reduce potential solar gain to the home and reduce the need for air conditioning.
