Green Mountain Estates, a.k.a. Green Mountainside, is located in Lakewood, Colorado. Green Mountain rises to about 6800 feet and features the William F. Hayden Park, a 2400 acre native open space, the second largest park in Lakewood. Reference: http://www.lakewood.org/HaydenPark/
The map below may be zoomed and scrolled in order to gain perspective to Denver on the east, the Rockies on the west, Golden to the north and Chatfield Lake to the south. The area of GMCA is bounded by Alameda Parkway on the south, Cedar Drive and open space on the north, Alkire Street on the east (all residences facing on Alkire), and Hayden Park on the west, all in Jefferson County.
Our actual boundary goes slightly further to the south to where Foothills Drive meets Alameda just across from the Green Mountain Recreation Center. If you click the minus button on the map you will see that final connection to Alameda Pkwy. Use the plus button to see additional street names.
