Install Six Monitoring Wells and Access Roads

Install Six Monitoring Wells and Access Roads

Construct three ground water monitoring wells adjacent to each of two existing leach fields for a total of six new wells in the Granite Bay area of Folsom Lake State Recreation Area. Installation of the monitoring wells is required by the Regional Water Quality Control Board as part of the Waste Discharge Requirements Order for the leach fields. Bore holes will be approximately eight inches in diameter and 50 feet deep. Bore holes will be maintained with PVC piping and maintained with locking watertight plugs and manholes at surface grade. In addition to drilling and installing the monitoring wells, construct four gravel roads and vehicle turn-around areas off of Granite Bay Road to the well sites to provide access for ongoing future monitoring. Approximately 1,200 feet of ten-foot wide gravel road will be constructed to provide access to the wells. An 18-inch diameter culvert and fill will be used to cross a ditch for one of the access roads. Pole gates will be installed at the entrances to the monitoring well access roads. One mature oak tree will require trimming, but otherwise, the road construction and well drilling activities will avoid the drip line of any mature trees. Nesting surveys will be conducted by a DPR-qualified biologist as needed if construction occurs during breeding season between March 15 and August 15. Construction activities will occur during the dry time of the year. No known cultural resource sites are situated in the vicinity of the project area. However, in the event that previously undocumented cultural resources are encountered during project construction, work will cease at the location of the find until a DPR-qualified archaeologist has evaluated the find and implemented appropriate treatment and disposition of the artifact(s)
