The ZPC is determined using a mathematical model that accounts for stream flows, gradient and area topography. The length of the ZPC is based on an additional five-hour time-of-travel of water in the streams beyond the perimeter of the ZCC, which creates a protection zone of ten (10) hours above the water intake.", "summary": "", "title": "GISTA_WM.GISTA.ZPC", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 0, "maxScale": 0, "spatialReference": "", "accessInformation": "", "licenseInfo": "" }
