tooriAft With the proposed recommendation, no capacity or sight distance constraints were * identified at the intersection. There will be no increase of traffic on Orono Orchard Road since the vehicles using the Woodhill Avenue access would normally travel Orono Orchard from OR 15 The third intersection is at OR 15 and Orono Orchard Road, which will experience a slight daily decrease (approximately 30) in both southbound left turning movements and westbound right turning movements. The reduction in cross-movements will increase safety for both OR 15 and Orono Orchard Road vehicles There will be a slight decrease in traffic on Orono Orchard Road from OR 15 to Woodhill Avenue. It will also greatly increase safety for Woodhill members who currently are required to make left- turns onto OR 15. The fourth intersection is at OR 15 and Woodhill Road, where a similar reduction (30 trips per day) in both eastbound left-tuning movements across OR 15 and southbound right-turning movements onto CR 15 will occur. The reduced conflicts will improve safety for CR 15 vehicles, and significantly improve safety for Woodhill members who are currently required to make the turn on and off CR 15 (50 mph). Geometric Design Issues Woodhill Country Club and Woodhill Avenue The design of the driveway on the Woodhill property and of Woodhill Avenue from the Woodhill Country Club property line to the current asphalt pavement does not present any traffic safety or design problem. The roadbed is the same grade and width as the road in place and used for many decades. The engineering drawing prepared by Coffin and Gronberg shows a gravel surface from the maintenance building to the property line and from the property line to the existing asphalt on Woodhill Avenue. Gradients on local streets should be less than 12 percent except in unusual conditions, (source; Residential Street 2^ Ed). The grade on the Woodhill Avenue public right of way from the stop sign to the property line is approximately 3%. The grade from the stop sign to 160 feet east is approximately 5%. On the Woodhill property between the maintenance building and the property line, there is on 50-60 foot section of the driveway that has an approximate 11-12% grade. Given the posted speed limit (10 mph), gravel paving (which slows down traffic) and approximate 160 foot distance from the western end of this driveway section to the stop sign, this grade section does not create any traffic safety concerns at the Woodhill Ridge private road intersection or on the driveway. Woodhill Avenue As presented in the Comparison of Access table below, the Country Club's Woodhill Avenue access provides a wider roadway surface, fewer driveway locations along its length, and connects with a roadway with lower speeds and traffic volumes than the present Woodhill Road.
