Notes:
Alternative turnaround options include a loop road and a t-shaped (also called a hammerhead) turnaround. Loop roads are semi-circular and provide two points of entry and exit, serving twice as many residential units as compared to cul-de-sacs (Bucks County, 1980). Hammerheads generate 75% less impervious cover than a 40 foot cul-de-sac but are generally only applied when streets are less than 200 feet long or when lot sizes are very large.
