Salisbury Street Raleigh, NC 27604 WATER RESOURCES DEPARTMENT July 20, 2016 Subject: MacGregor Pump Station Elimination Project (SW1168) Dear Madam: mk 2 l 2016 Please find (3) copies of the site plan for the MacGregor Drive Pump Station Elimination Project along with the buffer authorization forms and supporting documentation. The removal of existing sewer pump stations in lieu of gravity sewers is a top priority for the Town of Cary. The MacGregor Pump Station and nearby gravity sewer currently resides in Zone 1 and 2. The station footprint and two gravity sewer manholes are very close to the creek. All areas will return to natural cover once the demolition of the station is complete. See Attachment "A" for detailed map of Zone impacts and removals This project's proposed gravity sewer was designed to cross the stream buffers perpendicular. The sewer line to be bored does not cross the stream perpendicular; it must cross US HWY 1 perpendicular per NCDOT requirements. All the area in the temporary impacts for the gravity sewer installation are grassy or stone driveway. All stone driveway areas will return to natural cover once the sewer installation is complete. Thanks in advance for taking the time to review the plans. Please call my direct line at 919-380-2760 or email me at Jamie.bissonnette(cDtownofcary.orq if you require any further information.
