C-12 Provide survey control benchmark location in Town of Vail General Note #31. L-1 The water line alignment looks as if it will impact the existing trees near Buffehr Creek Rd. Please show the impacts to these trees. Also most of the future landscaping along the S. Frontage Rd. is proposed to be planted in areas that are in conflict with future and existing utilities. The notes on the plan regarding these conflicts are not adhered to. This landscaping will require approval from the impacted Utilities; or the landscaping or utilities need to be relocated to a better location. The landscaping in CDOT ROW will require CDOT approval. L-1 Planting plan conflicts with bus shelter. L-1 The sight distance triangle is shown on the entrance, this should be shown on the exit.
