• All construction equipment will be pressure washed/steam cleaned before entering the parks to ensure that all equipment and machinery are weed-free.

• Haul trucks bringing fill materials from outside the parks will be covered to prevent seed transport and dust deposition along the road corridor.

Prevention of Invasive Species Introduction All aggregate sources must be approved as "noxious-weed-free" before acceptance. This is to prevent the introduction of invasive non-native species into the park. The vendor must implement mitigation measures where necessary, such as stripping the top 12 inches of source material, requiring fresh material stored for less than one week, or sterilizing the material.
