Purpose of the project is installation by USGS of one Earthquake Early Warning System station in Chino Hills State Park (latitude 33.910908, longitude -117.683528) to provide advance warnings that will allow people and systems to take actions to protect life and property from destructive shaking. The station will occupy a 20’ wide by 20’ long footprint. See Exhibit A – Plan Drawings. The station will be solar powered, will not generate noise, will not impede public access to surrounding areas, is low profile, and is encapsulated to prevent animal damage. Construction will
occur over 3-4 days. Installation and maintenance to occur only when no threat to sensitive species. State Parks anticipates no water table interaction or soil erosion to occur. No closure to roads is necessary. No new roads or access routes are necessary. Minor vegetation removal from excavation activity would be limited to annual grasses. See Exhibit B – Site Photo
No potential for significant impact to the environment is anticipated in compliance with CEQA §15300.4. If the project is implemented as indicated within the CDPR Project Evaluation Form, then it is exempt under CEQA §15305 – Minor Alterations to Land for both the installation activity and the Department’s Right to Enter Permit process.
