The County’s CEQA Transportation Analysis Manual recites this definition. Haul trucks are classified as “heavy trucks” for which VMT thresholds do not apply; nonetheless the potential reduction in haul truck VMT is assumed to be similar to the potential reduction in automobile VMT given that employees and visitors in automobiles would likely have a similar distribution as the haul trucks, as defined previously under Trip Distribution. Finding – As the North County Landfill is more centrally located to its userbase than the Foothill Landfill, the consolidation of activity among the two landfills to just the North County location would reduce VMT and therefore this project would be presumed to have a less-than-significant impact to VMT. Safety The potential for the project to impact safety was evaluated in terms of the adequacy of sight distance and need for turn lanes at the project access as well as the adequacy of stacking space at the study intersections to accommodate additional queuing due to adding project-generated trips. This section addresses the third transportation bullet on the CEQA checklist which is whether or not the project would substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment). Site Access Sight Distance Sight distances along East Harney Lane were evaluated based on sight distance criteria contained in the Highway Design Manual (HDM), Caltrans, 2020. The HDM requires adequate corner sight distance to be available for drivers entering from the driveway of traffic on the cross street, as well as stopping sight distance for a driver on the cross street following another motorist that is slowing to turn into the site.
