Both parcels have a County of San Luis Obispo combining designation of Geologic Study Area, and a small portion of APN 012-361-018 has a County of San Luis Obispo combining designation of Renewable Energy.

Document Description
The project includes upgrades to the existing HRCSD water treatment plant and spray field to comply with Waste Discharge Order No. R3-2017-0026. The project would include modification and demolition of the existing HRCSD wastewater treatment plant elements and construction of new water resource recovery facility elements and supporting facilities with an average annual daily flow capacity of approximately 0.29 million gallons per day. In addition, a new, eight-inch-diameter effluent pipeline would be installed along Heritage Road and Gateway Drive to replace the existing, aging six-inch diameter pipeline. Modifications at the spray field location would consist of demolition and abandonment of the sand filters and replacement of the de-chlorination facilities with a more robust de-chlorination process. No modifications to the storage pond located adjacent to the existing spray field would occur, and discharges to the storage pond would remain the same as under existing conditions. The total wastewater treatment capacity of HRCSD under the proposed project would not be increased as compared to the existing capacity of HRCSD’s wastewater treatment facility.
