California Motocross Park Noise Analysis

HMMH prepared a noise study for the proposed California Motocross Park to comply with Placer County environmental requirements. The 158-acre park is planned to consist of several outdoor motocross tracks for various sizes of motorcycles, all-terrain vehicles, and BMX bicycles, as well as a partially-enclosed arena with a motocross track.

To determine compatibility of noise from the proposed Park with residential areas nearby, HMMH conducted measurements of existing noise levels in these areas and used the SoundPLAN® model to project worst-case noise conditions at the homes.

HMMH’s noise study showed that the facility would comply with two different county noise requirements. Even under worst-case conditions, noise levels from the facility are expected to be well below existing ambient noise levels.
