of the development that do not meet adopted level of service standards. The applicant's Traffic Safety and Street Connectivity Study provides evidence that that the roadway system in this area is currently meeting adopted levels of service standard. The City has not identified any streets in the vicinity where LOS performance standards are not met. While disputing the applicant's conclusions, the Response Committee's traffic analysis does not provide any evidence to indicate that the LOS performance standards are not met. Based on the evidence in the record, the hearings official agrees that the proposed PUD does not meet any of the threshold requirements for a TIA under EC 9.8320(5)(c). Based on the above analysis, the proposed PUD complies with the requirements of EC 9.8320(5)(a) and (b) to provide safe and adequate transportation systems. EC 9.8320(6) The PUD will not be a significant risk to public health and safety, including but not limited to soil erosion, slope failure, stormwater or flood hazard, or an impediment to emergency response. Finding: Soil Erosion: The applicant provided an analysis to demonstrate that the proposed PUD does not pose a significant risk due to soil erosion. Because of the size of the proposed development, an erosion prevention permit will be required before any ground disturbing activities. Slope Failure: The applicant's evaluation of risk due to `slope failure' is included in the applicant's geotechnical investigation. That investigation concludes that the proposed development is feasible from a geologic and geotechnical perspective, and that the proposed development will not adversely impact the proposed site or adjacent properties. As it relates specifically to slope failure, the applicant's investigation states: No indications of significant active or recent slope instability (such as tension cracks, sunken grades, springs, bare soil head scarps or incised erosional channels) were observed during reconnaissance. Soil creep indicated by fir trees with curved trunks is common, and quite extreme in places. Slopes below the proposed loop road are slightly hummocky due in part to logging activities, but there were no indications of recent or extensive slope failures observed. The Ribbon Trail is buttressed by low wooden cribbing in places, but no culverts or indications of high runoff were observed. The steeper slopes are generally vegetated with middle-age to relatively mature trees up to 3 feet or more in diameter and in our opinion appear to be relatively stable. Ferns are common on the steeper slopes, but other wetland type species are not. Branch Engineering Geotechnical Investigation, February 6, 2017. By its terms, the applicant's geotechnical report is a preliminary investigation and also includes numerous specific recommendations to minimize any potential for slope failure.
