Clearly, the use of this property has been allocated from DHHS to the North Carolina Department of Public Safety (NCDPS, 1969) and then from (NCDPS) to the North Carolina National Guard (NCNG, 2018) for use as a Regional Readiness Center. This correspondence will serve as the original owner's consent form. On line 9 of the Financial Responsibility Form (FRO) required for the erosion and sediment control plan submittal, I recommend leaving the State Hospital listed as the owner of the property as it now appears on the form. A signed authorization to disturb will be required from North Carolina National Guard for the Financially Responsible Party (the company who performs the work) to (1) submit an erosion and sediment control plan, and (2) to conduct the land disturbing activity. Thank you for the time and effort spent obtaining this information.

Please review the forwarded email thread along with the attachments and supply your office's opinion on the issue. In review of the parcel at 5161 Western Avenue, Morganton, via Google Earth, DPS has two (2) facilities in operation on the parcel in question. The reallocation between DHHS and DPS occurred in February 1969, see plat and deed PDF, and the issue seems to be a listing error at the Burke County Register of Deeds GIS that lists the State Hospital. DHHS is of the mind, that the reallocation occurred in 1969 and that DPS is the steward of the property since full execution which would lead the DHHS no role in the upcoming construction project or required documentation.

At your direction, this investigation was limited in scope to the proposed stormwater BMP locations on the site, as illustrated on the attached drawing. The investigation was completed on January 14, 2017. Depth to SHWT was determined using accepted soil science practices. A hand auger was used to advance vertically into the native soil until redoximorphic features (often mistakenly called "mottles ") with a chroma of 2 or less were observed. True mottles that meet this color criterion that are the result of parent material coloration are ignored, as these are not indicative of the seasonal high water table. Four hand auger borings were advanced in the locations proposed for the stormwater BMPs per the drawing referenced above. In borings 1 and 3, chroma 2 redoximorphic features indicative of the SHWT were not observed in the borings to a depth of 168 inches below the soil surface. In boring 2, auger refusal was experienced at 118 inches below the soil surface. In boring 4, auger refusal was experienced at 72 inches below the soil surface, The table below lists the observed SHWT depths below the existing soil surface. Boring ID Auger Refusal inches SHWT Depth' (inches) SHWT Elevation a,pproximato 1 N/A > 168 < 1198.00 2 118 N/A < 1222.17 3 N/A > 168 < 1198.00 4 72 N/A < 1216.00 Depth below existing soil surface CIVIL ENGINEERING I ENVIRONIIIENTAL I SURVEYING I GIS I LANDSCAPE ARCHITECTLIRF j CONSTRUCTION SERVICES Thank you for the opportunity to assist you with this seasonal high water table investigation for this site.

Clearly, the use of this property has been allocated from DHHS to the North Carolina Department of Public Safety (NCDPS, 1969) and then from (NCDPS) to the North Carolina National Guard (NCNG, 2018) for use as a Regional Readiness Center. This correspondence will serve as the original owner's consent form. On line 9 of the Financial Responsibility Form (FRO) required for the erosion and sediment control plan submittal, I recommend leaving the State Hospital listed as the owner of the property as it now appears on the form. A signed authorization to disturb will be required from North Carolina National Guard for the Financially Responsible Party (the company who performs the work) to (1) submit an erosion and sediment control plan, and (2) to conduct the land disturbing activity.

Please review the forwarded email thread along with the attachments and supply your office's opinion on the issue. In review of the parcel at 5161 Western Avenue, Morganton, via Google Earth, DPS has two (2) facilities in operation on the parcel in question. The reallocation between DHHS and DPS occurred in February 1969, see plat and deed PDF, and the issue seems to be a listing error at the Burke County Register of Deeds GIS that lists the State Hospital. DHHS is of the mind, that the reallocation occurred in 1969 and that DPS is the steward of the property since full execution which would lead the DHHS no role in the upcoming construction project or required documentation.

Important maintenance procedures: Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. - Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. BMP element: Potential problem: How I will remediate the problem: The entire BMP Trash/debris is present. Remove the trash/debris.
