Administrative Draft Environmental Impact Report Gill Medical Center Project According to County Development Title requirements, the minimum buffer width shall be 100 feet, measured from the mean high-water level of the natural bank or fifty (50) feet back from the existing habitat, whichever is greater. Although not currently planned, water-dependent uses, such as stormwater retention basins, may be permitted within this buffer. 3.6.5 Utilities The Project site is not currently served by public water, sewer, or storm drain Utilities. Therefore, the Project includes construction and phased expansion of onsite Utilities to serve the Project.The ultimate Utility improvements are shown on Figure 3-7. Grading and Utility Plan and are sized to serve full project buildout. Phase 1 utility improvements would be sized to accommodate Phase 1 demands and would be designed for efficient expansion commensurate with development phasing. The individual utilities are further described below. 3.6.5.1 Water According to a technical memorandum prepared by Siegfried Engineering, Inc. (2020), the Project's potable water demand is approximately 37,300 gpd, or 41.8 acre-feet per year (Phase 1 demands of approximately 4,800 gpd, or 5.4 acre-feet per year; and, Phase 2 demands of approximately 32,500 gpd, or 36.4 acre-feet per year). Potable water would be provided via an onsite Small Public Water System (SPWS) that would be permitted through the State Division of Drinking Water (DDW), with groundwater serving as the source supply. As shown on Figure 3-7, groundwater would be pumped from an onsite well or wells and transmitted via underground pipeline to potable water storage tanks located on the northern point of the Project site. From there smaller pipelines would distribute water to indoor potable use areas, fire hydrants and building sprinkler systems as shown in Figure 3-7. If required by the DDW as part of the SPWS permit, treatment of the water prior to distribution may be required. 3.6.5.2 Wastewater Wastewater The Project is outside of the area served by a municipal sanitary sewer system.Therefore, the Project includes its own onsite sanitary sewer and wastewater treatment system.Wastewater generated by the Project would be conveyed by underground piping to an advanced "package plant"wastewater treatment system constructed near the northern site boundary, west of the water storage tanks (Figure 3-7). The treatment process would be specially designed to treat/remove hospital generated liquid medical waste. The resultant water quality would be treated to a level suitable for National Pollutant Discharge Elimination System (NPDES) permitting by the Regional Water Quality Control Board with Waste Discharge Requirements (WDR). Treatment to this level would produce "recycled water" suitable for use in outdoor reflecting ponds, as landscape irrigation, or for agricultural production.
