Tree branches hang over a river in Bear Creek Lake Park.

The City of Lakewood has received a Tree City USA award for 39 years running, and it's no mystery why.

The city boasts an extensive park system and miles of urban forests lining city streets. Parks staff have extensive experience maintaining approximately 6,000 trees within parks and 33,000 street trees. They also maintain the trees located in Lakewood's two public golf courses, Bear Creek Lake Park, Bear Creek Greenbelt, and William F. Hayden Park on Green Mountain.

About City Pesticide Use

Lakewood Parks is very cautious with the use of pesticides in order to protect our environment and park users. Our staff have extensive training and certifications, wear protective clothing and do not use any glyphosates in the parks system.

Other Lakewood pesticide facts:

  • Staff only spot spray as needed.
  • There are four pesticide free parks in Lakewood including Rampart, Taft, Lakewood Estates and Ken Knutsen Parks.
  • Staff use horticultural vinegar as a burn down product for weeds whenever possible. Pesticides are categorized by toxicity rating from “caution” to “warning” and finally “danger.” Lakewood Parks uses products that are labeled with the lowed toxicity rating of “caution.”
  • Lakewood Parks does not treat outside of the parks system and will not treat private property.
