Sanderson Gulch Environmental Information

Soil Contamination:

Sanderson Gulch is like many other rivers throughout Denver which were used as dumping grounds for trash and construction debris during the early development of the City. Due to this fact, the dirt or soil along the river banks contain contaminants that will need to be mitigated as part of this project. Air monitoring and other safety measures per federal and state requirements will be strictly followed.

Sanderson Gulch Safety

Basic S Safe fety T y Tips

• Avoid walking or driving through flood waters.
• Just 6 inches of moving water can knock you down, and one foot of

moving water can sweep your vehicle away.

• Avoid camping, parking along streams, rivers, and creeks during heavy
• rainfall. These areas can flood quickly and with little warning.
• Never enter, play or camp in a pipe, culvert or confined space as it could

result in death.
