Field Investigation Report: New Bern Convention Center Page 2 Narrative Description: The property is located contiguous with the Trent River at or near the confluence of the Trent and Neuse Rivers, in New Bern, Craven County. The property is bordered on the north by South Front Street and on the east by East Front Street and on the south by the Trent River. This property is currently developed for commercial and public use as a convention center. The adjacent developed properties include a commercial hotel with a marina to the west; paved parking areas to the north; East Front Street Right of Way to the east and Union Point Recreation Center is east of East Front Street. The City of New Bern owns the riparian 30' wide strip of land running parallel with the shoreline which is paved with concrete and used as a boardwalk. The elevation of the high ground of the parcel averages 7' above the normal water level (nwl). Vegetation on the parcel mainly consists of planted trees and landscaped lawn. The 3.04-acre has approximately 532 linear feet of continuous shoreline along the Trent River within the project site There are no coastal or non -coastal wetlands within the project area. This area is considered as Urban Waterfront and is located within the Division of Water Resources Neuse River Riparian Buffer Area. This property is located within the New Bern Historic District and is registered with the National Historical Registry. The Trent River is classified as Joint Waters at this location and the Neuse is classified as Coastal Waters in this area. There is not a cultural resource within the project property. The Trent River is approximately 1,315 feet across at this location. These waters are not classified as a Primary Nursery Area. Submerged aquatic vegetation is not present at this location. This area is closed to shellfish harvest and is classified as SB; Sw; Nutrient Sensitive Waters. There is no development proposed waterward of the normal water level. This project requires a NCDEMLR Stormwater Permit modification and a Neuse River Basin buffer authorization from the NCDWR which triggered the CAMA Major Development Permit application. Proposed Development: The existing New Bern Riverfront Convention Center proposes to enlarge their outdoor patio space. The proposed multi -level patio would increase the amount of impervious surface on the site. Through innovative design, there would be two infiltration basins proposed to treat the increased impervious area. The onsite soil consists of loamy sand to sand. The site currently runs off directly into the Trent River which is a tributary to the Neuse River. The proposed site improvements would increase the onsite impervious area 2,274.28sf. The site design would provide two small infiltration basins that would treat 5,838.38sf of total drainage area, 5,553.9sf of which is impervious. The infiltration basins would trap the 1.5" storm runoff and allow the runoff to infiltrate the natural ground at a rate of 1.1 IN/HR as per the engineering report. Roy Brownlow . March 11, 2020 Morehead City Field Investigation Report: New Bern Convention Center Paae 3 Post -development runoff would be less than the existing conditions because of the proposed infiltration basins. The impervious surface area that would drain into the existing stormwater control would be reduced by 3,279sf. The proposed project would involve removing existing impervious areas in the 75 AEC area and locating it closer to the existing building to create a more useable patio area for the convention center. The current patio and sidewalk configurations limit use of this space according to the project engineers. The project would re -locate the patio area closer to the existing building while removing existing sidewalk area scattered around the yard. The total 75' Estuarine Shoreline AEC area onsite is 23,225sf. There is 8,329sf of existing impervious surface within the total 75' AEC. Approximately 5,161 SF of existing impervious surface would be removed and 3,850sf would be re -developed within the 75' AEC. This would result in an impervious area reduction of 1,311sf within the AEC area or a total impervious cover of 7,018sf (30.2%), which is less than the existing impervious coverage. The total disturbance in the 75' AEC area would be 15,568sf. This is largely due to the areas of existing impervious surface that would be removed and the proposed grading that would be necessary to these areas after completion. Silt and sedimentation barrier fencing would be used to control and retain the sediment onsite and to prevent it running off into the adjacent waterbody. The existing developed area in the Neuse River Basin Zone 1 of the buffer would be redeveloped by removal of 806sf of impervious area and a lower amount of 248sf of impervious area would be placed back over the previously developed area. The total disturbance within 30' of NWL would be 4,159sf. The total ground disturbance in the Neuse River buffer area would be 16,634sf. Anticipated Impacts: As this project is proposed to connect to the waterfront boardwalk, the project would impact the estuarine shoreline to within 12.5' of the NHW line (Bulkhead). There are no wetlands onsite and no.development is proposed within public trust or estuarine waters. The proposed design includes the use of sand filters for stormwater runoff treatment. According to the project design engineers, these sand filters would capture more area than is required. The proposed infiltration systems would provide more stormwater treatment than the existing conditions onsite according to the project engineers. Impacts include temporary high ground shoreline disturbance as a result of the removal of the existing sidewalk and the associated grading and landscaping. Long term impacts would include the replacement of the sidewalk although at a reduced impervious surface area than the existing development. Effective sedimentation barriers and measures between the project site and the adjacent waterbody would remain in place until a vegetative cover could be replaced and established. This proposed project would .Roy Brownlow March 11, 2020 ' Morehead City Field Investigation Report: New Bern Convention Center Paae 4 reduce the amount of stormwater runoff from the property into the Trent River through innovative stormwater design and as a result, the stormwater treatment would be improved.

From US HWY 70 East take E Front Street to the North across the Trent River. Turn left onto S. Front Street and the destination is immediately on the Left. Project Description The existing New Bern Riverfront Convention Center is enlarging their outdoor patio space. Stocks Engineering is contracted with the Oakley Collier Architects for the civil engineering aspects of the design and permitting process. The proposed multi -level patio will increase the amount of impervious surface on the site and two infiltration basins are proposed to treat the increased impervious area. Stormwater Management Plan The onsite soil consists of loamy sand to sand. The soil is Seabrook -Urban land complex (A Soils) Soils information was obtained through the NRCS website: http://websoilsurvey.nres.usda.gov/app/ for Wake County. The site currently drains directly into the Trent River which is a tributary to the Neuse River. The proposed site improvements increase the onste impervious area 2,274.28 SF. The site design provides two small infiltration basins that will treat 5,838.38 SF of total drainage area, 5,553.9 SF of which is impervious. The infiltration basins trap the 1.5 - INCH storm and allows the runoff to infiltrate the natural ground at a rate of 1.1 IN/HR. Post -development runoff is less than pre -development because of the addition of the infiltration basins. The impervious area that will drain into the existing stormwater control measures was reduced by 3,279.62 SF. CAMA Specific Narrative The project involves removing large amounts of impervious areas in the 75 AEC area and locating them closer to the building to create a more useable patio area for the convention center. The current patio and sidewalk configurations do not allow the wise use of this space. The project will locate a larger and flatter patio area adjacent to the building while removing sidewalk scattered around the yard. The Total 75' AEC area onsite is 23,225 SF. There is 8,329 SF of Existing Impervious in the Total 75' AEC Area. Approximately 5,161 SF of Existing Impervious is being removed and 3,850 is being replaced within the 75' AEC Area. This results in a final impervious area reduction of 1,311 SF within the AEC area or a total impervious of 7,018 SF (30.2%) The total disturbance in the 75' AEC Area is 15,568 SF. This is largely due to the large areas of impervious being removed and the need to grade these areas after completion. Silt fence will be used to control and retain the sediment onsite. The area just in the 30' CAMA Buffer will have 806 SF removed and 248 SF of imperviouREGENED back. The total disturbance within just this area is 4,159 SF. MAR 0 6 2020 DCM-MHD CITY The area just in the 50' NCDEQ Buffer will have the 806 SF removed as discussed in the 30' Buffer area above plus an additional 1,563 SF in the outer 20' for a total of 2,369 SF. The total proposed impervious to be added back to this area is 550 SF. The total disturbance in this area is 16,634 SF. As this project has to connect to the waterfront boardwalk, the project will impact to within 12.5' of the NHW line (Bulkhead). There are no wetlands onsite. The proposed design includes the use of Sand Filters for Stormwater treatment. These sand filters capture more area than is required and allows for more treatment than the current conditions onsite. Short term impacts include the removal of the existing sidewalk and the associated grading. Long term impacts would include the replacement of the sidewalk although at a much lower surface area than the existing site.

Although Federal architectura was New Bern's special forte, a variety of other styles are represented. The minor streets are quiet, punctuated by buildings set on large well-landscapE d lots shaded by stately trees dotted with clumps of mistletoe. Adding serenity to the town are the Neuse and Trent rivers which provide a magnif- icent backdrop. This atmosphere prevailed throughout Now Berm until the early 1950s when Broad Street became a major east -west artery, cleaving the city in two. I -Then the city was established in 1710, at the request of Baron von Gra£fenried, John Lawson devised and laid out the plan which with some additions remains intact. He explains: Since in America they do not like to live crowded, in order to enjoy a purer air, I accordingly ordered the streets to be very broad and the houses well separated one from the other. I marked three acres of land for each family, for house, barn, garden, orchard, hemp field, poultry yard and other purposes. I divided the village like a cross and in the middle I intended a church. One of the principal streets extended from the bank of the River Neuse straight on into the forest [Broad or Pollock Street] and the other principal street crossed it, running from the Trent River clear to the house River [Paddle or Craven Street]. After that we planted stakes to mark the houses and to make the principal streets along and on the banks of the two rivers [East Front Street and South Front Street (now Tryon Palace Drive)]. Not only did the street scheme survive, but the idea. of not lilting to "live crowded" is still in evidence. With the exception of construction accom- plished since the mid -twentieth century and four mid -nineteenth century row houses, all residences are separate free-standing buildings, each with a generous yard. Historically New Bern has been dependent for its livelihood on its rivers and on governmental sponsorship. The city's role as occasional hoot of the itinerant colonial assembly, the colony's first permanent capital, and the seat of Craven County helped foster her emergence as a.port and therefore as a mercantile center. Shortly before the Revolution, Governor Josiah Martin observed It is true . the Town of Beaufort, is advantageously situated for commerce, but there are no persons of condition or subUahce in it, and the Trade that was formerly carried on through that channel, is now derived almost entirely to this Totm [flew Bern], since it became the seat of government, which has promoted its growth exceedi IT inviting many considerable Merchants to settle in it. Because of New Be.rn's externally oriented econo:=L, the city was exposed to national stylistic trends which quitvr obviously hd a great affect on her W m m a u, ;o Form 10-300o UNITED STATES DEPARTMENT OF TIIE INTERIOR IsTA (July 1969) NATIONAL PARK SERVICE N NATIONAL REGISTER OF HISTORIC PLACES COUNTY Craven INVENTORY - NOMINATION FORM FOR NPS USE ONLY (Continuation Sheet) ENTRY NUMBER DATE 7. A architecture. The vast majority of her structures express a high degree of academicism successfully rendered by skilled and sensitive craftsmen. Nothing remains of the earliest buildings. A comparison of New Bern today with what C. J. Sauthier recorded on his 1769 map of the town finds only four buildings which tentatively are identified as surviving from that time. (Tryon Palace, most of which is.a reconstruction accomplished in the 1950s, is not included in this figure.) William Attmore saw the town in 1787 and provided the following descrip- tion of the buildings: There are[,] to many of the houses[,] Balconies or Piazzas in front and sometimes back of the house, this Method of Building is found convenient on account of the great Summer Heats here --These Balconies are often two.Stories high, sometimes one or both ends of it [them] are boarded up, and made into a Room. Within the district, fourteen buildings with Georgian stylistic origins ha.va been identified. The majority of them are simple, modest d::ellinga anal most were up -dated during a later stylistic era. The surviving Georgian buildings are: Brinson House, 213 Johnson -Street House, 217 Hancock Street Mary Hatch Harrison PIouse, 219 New Street Elijah Clark House, 619 Middle Street House, 713 Pollock Street Dr. Forbes House and Office, 715-717 Pollock Street House, 726 Pollock Street Coor-Gaston House, 421 Craven Street Coor-Bishop House, 501 East Front Street Jobn Wright Stanly House, 307 George Street Hawks House, 306 Hancock Street Srd th-Whitford House, 506 Craven Street Major James-Daves House, 313 George Street York -Gordon House, 213 Hancock Street This is a scant number considering that more than thirty house carpentors and/or joiners are known to have been working in the county betaa en 1748 and 1790. With the exception of a few houses attributed either to John Hawks or to James Coor, the architect -builders of most buildia.-s cannot ba identi- £:i.;�i. It can be assumed that natural attrition combined with disasters lika tha hurricane of September, 1769, and thr fires in the fall of 1'191 and 1794, c.nd that of February, 1798, which burned the Covernor's Palace, eradicated Tu3ch of the evidence of the early towm.

B I ENTRY NUrARER I DATE I Within the last two decades of the eighteenth century the population of NEW Bern more than doubled, and the physical area of the town accordingly expanded north and wrest. Judging from remaining evidence, growth of the population and area continued in the first decades of the nineteenth century. Obviously the town was enjoying a new high level of prosperity --a prosperity based on commercial and mercantile endeavors which enabled affluent merchants like John Harvey, Eli Smallwood, and Isaac Taylor to build ambitious town houses. It was during this same era of prosperity that the town produced civic and cultural symbols of urbanity, most notably the New Bern Academy, the Masonic Temple and Theater and the First Presbyterian Church. The New Bern version of Federal architecture is Adamesque; it is re- strained and elegant and, above all, sophisticated. A typical Federal domestic structure has the following elements: two -and -one-half stories; a side -hall plan, two rooms deep (three bays wide and four bays deep); a gable roof; gable dormers; exposed -face interior end chimneys; a one -bay pedimented porch; an entrance composed of a six -panel door (four flat above two flush panels) with geometrically ornamented transom. above. Although interior treatments vary considerably, three-part mantels are univeroal. The following buildings generally adhere to those characteristics: Bryan House and Office, 605 Pollock Street Eli Smallwood House, 524 East Front Street Benjamin Smith House, 210 Hancock Street Stevenson Houses 609 Pollock Street Isaac Taylor House, 228 Craven Street Eubank House, 218 Broad Street Leech House, 209 Change Street (formerly on west corner of East Front and Linden streets) IIouse, 231 Change Street House, 125 Craven Street Stevenson House, 413 Craven Street House, 223 Craven Street Jonee-Jarvis house, 528 East Front Street Eleanor Marshall House, 227 Eden Street Gull Harbor, 514 East Front Street House, 419 Metcalf Street Headmasters Houso, 102 Johnson Street Jarkins-Moulton House, 309 Johnson Street House, 311 Johnson Street Hendren House, 412 Middle Street William Hatch Bryan House, 607 Pollock Street idcKinlay=paves House, 613 Pollock Street IIouse, 815 Pollock Street Lewis-I•ihitshurst douse, 403 Queen Street House, 813 Broad Street House, 211 Broad Street Fenn 10•?00aUNITEC 5.

C While the side -hall plan was certainly the most prevalent Federal form, center -hall and asymmetrical versions were built as well. A concentration of those which survive occurs on Pollock Street in the area west of Tryon Palace, but others are scattered throughout the town. Usually they are two or two -and -one-half story frame structures (three brick) with gable roofs (three with gambrel roofs) and Federal interior woodwork. These structure; which range from quite modest to vary elaborate, in- clude the following: Attmore-Oliver House, 513 Broad Street Harvey Mansion, 519 Tryon Palace Drive Simpson-Oaksmith-Patterson HOUSE, 226 East Front Street Tisdale -Jones House, 520 New Street Jones House, 231 Eden Street House, 718 Pollock Street House, 801 Pollock Street House, 812 Pollock Street House, 819 Pollock Street House, 823 Pollock Street ' House, 309 Bern Street James Bright House, 516 Craven Street Oliver House, 512 East Front Street Vail -Clarke House, 519 East Front Street Silas Latham House, 816 Pollock Street Mitchell -Bryan House, 221 Johnson Street House, 206 Metcalf Street Clarke House, L19 Metcalf Street McLin-Hancock House, 507 Middle Street House, 501 New Street House, 206 Change Street Hatch -Washington House, 216 Pollock Street In the Federal era the authorship of several buildings can be attributed with varying degrees of certainty to Martin Stevenson, Jelin Dewey, Robeirt Hay, and Uriah Sandy, .four of some forty architect -builder„ established in the county between 1790 and 1835• As in the Georgian era, this leaves the majority of structures unlinked to a specific designer. The Federal style persisted in New Bern well into the 1840s, long after it had been superseded by the Greek Revival style in other towns. Thia a,as by no means a result of cultural lag; rather it would seem more likely to be a product of conservative mercantile interests, a propositicn set .forth by Talbot Hamlin in Greek Revival Architecture in Amarica: There were great mercantile and shipping interests, prti_cularly of Boston and Philadelphia, for whom England and the English colonies were still the best --and almost the only --customers.

D tism often necessarily persisted, owing to the fact that many of the skilled craftsmen of the country were either English -trained or but one generation removed from England, and to the fact that, in archi- tecture at least, all of them depended largely on English books. The importance of such mercantile interests in New Bern, combined with the habits of the craftsmen, provide a cogent explanation for the longevity of the Federal style in the city. The town clung so tenaciously to Federal architecture, in fact, that it scarcely acknowledged the existence of other styles. Concessions to the Greek Revival style usually appear on the interiors of buildings and tare the form of syrmRetrically molded architraves with corner blocks. In only a very few cases are classical Greek motifs employed externally. The following buildings are stylistically transitional; they display the full range of application of Greek Revival motifs in and on basically Federal forms: St. Paul's Roman Catholic Church, 510 Middle Street Jerkins -Duffy House, 301 Johnson Street House, 820 Broad Street Justice House, 221 East Front Street House, 227 East Front Street House, 620 Craven Street Sparrow -Daniels House, 222 East Front Street Dr. Snallwood's House and Office, 501-505 Craven Street House, 208 Johnson Street Benjamin Ellis House, 215 Pollock Street Alexander Miller House and Store, LIN Broad Street William Hollister House, 613 Broad Street Primrose House, 318 Craven Street Jerkins -Bryan House, 520 Craven Street By the time New Born rejoined the mainstream of architertural trends, the Greek Revival style was waning, and mid -nineteenth century eclecticism was flourishing. The town began to experiment with the now styles in the 1840s. The incidence of buildings constructed in the pre -Civil War eclectic era is lower than that of earlier eras. Probably in part this is due to the leveling -off of both the population and wealth of New Bern. Although others existed, only one early Italianate dwelling survives, that being the Thomas Jerkins House (305 Johnson Street). The Edward R. Stanly House and Dependent (501 Pollock Street) and the Slover-Bradham House (201. Johnson Street) are rendered in the Renaissance Revival style. The stately massiveness of the Slover-Bradham House is unrivaled in the town and in the state; indeed it would fit quite comfortably amid the town houses on Beacon Hill in Boston. During this era the congregation of the First Baptist Church elected to build a now ediface (northwest corner of I4iddle Street and Church Alley), and obtained a Gothic Revival design from the New York firm, Thomas mid Son. crua:I.+:: Form 10{:OG, UNITED STATES DEPARTMENT OF THE INTERIOR STATE (July 1969) NATIONAL PARK SERVICE Nort: NATIONIL REGISTER OF HISTORIC PLACES C.UNTY INVENTORY • NOMINATION FORM I graven FOR NIPS USE ONLY (Continuation Sheet) ENTRY NUMBER DATE (1VvmEe, eu 7. E While participating in -the national architectural mainstream, Now Bern re- tained a degree of independence of design and materials as evidenced in the coquina wall and arched gateway. of Cedar Grove Cemetery constructed by the torn in 1854. The post -Civil War era saw New Bern fully integrated into the prevailin national stylistic modes --Second Empire, late Italianate Revival, Romanesque Revival, Queen Anne, Stick Style) Eastlake and Shingle. Christ Church (Pollock Street between Craven and Middle streets) was rebuilt between 1871 and 1875 in a late Gothic Revival style and in 1887 had the Stick Style porch added. A substantial portion of the late nineteenth century domestic structures, especially the more massive ones, have met with destruction, but a few of them, plus a number of smaller, more manageable houses survive: House, 310 New Street Judge Manly House, 515 East Front Street House, 516 Johnson Street Harvey Wadsworth house, 515 Broad Street Ulysses S. Mace House, 518 Broad Street Stinson House, 605 East Front Street Senator Simmons house, 415 East Front Street House, 616-618 East Front Street House, 408 Hancock Street George Slover House, 209 Johnson Street Former First Baptist Church Parsonage, 304 Johnson Street Roberts House, 501 Metcalf Street Foy -Munger House, 516 Middle Street Hollowell House, 614 Middle Street House, 207 Pollock Street House, 224 Pollock Street Street House, 509 Pollock Street House, 516 Pollock Street Mitchell House, 212 Tryon Palace Drive Wade House, 214 Tryon Palace Drive In the early twentieth century New Bern experienced a building boom which in volume came close to rivaling the Federal boom. The economic re- vitalization of the torn was largely a result of the lumber industry which produced magnates desirous of living in and capable of paying for the most impressive houses their money could buy. Obliging these clients was a local architect, Herbert Woodlry Simpson, who is credited with the design of every important structure built in New Bern in the first two decades of the twentieth century. A versatile designer, Simpson excelled in the Queen Anne and Neo-Classic Revival styles and often combined the two. While practicali and "progress" have taken their toll of many of his impressive N9o-Classic Rs7i val structures, a few have survived.

Yet it was in the post -Revolutionary period that New Bern underwent a dramatic architectural efflorescence that produced a body of urban Federal buildings of academic sophistication and superb craftsmanship seldom rivaled in the country. The typical dwelling of this period was a side -hall plan town house enriched with delicate, inventive yet restrained ornament inside and out --epitomized in the Eli Smallwood House. The same elegance characterizes such institutional buildings as the New Bern kc-6am3r the Masonic Temple and Theater, and the First Presbyterian Church. Not onl; are New Bern's Federal buildings of the highest quality; a remarkable number --over fifty --survive, most in good condition, and rally still e.:ist in their original_ context and are used for their original purpose. `ha tenacious hold of .the style only gradually gave tray to the eclecticimr, of the later nineteenth century, but this period, as well as the early twentieth century, produced a remarkable collection of handscaie domestic and institutional buildings that are an important part of the architectural fabric of the town. Now Bern, with much of its atmosphere, scale, and ambiance still remarkably intact, exhibits a range, sophistication, and excellence of architectural styles unique in North Carolina, highlighted by a collection of Federal structures of major national significance. New Bern, settled by German Palatine and Swiss colonists under Baron Christoph von Graffenreid in 1710, is at the confluence of the Trent and Meuse rivers. Problems with the '_Tuscarora Indians in the area and the death of the group's leaders retarded the growth of the town, but the early settlers make important contributions: the selection of a site and the establishment of a settlement, the design of the town plan and the conferri of a name --New Barn --after the settler's home canton in Switzerland. Da.spiVe the 1711 massacre by the Tuscaroras, the town survived and grew stead:LI , sq that by the mid -eighteenth century it had achieved considerable imporu_nuo.; In 1712, the area called Craven, was a precinct of Barth Coim ty, end by 1722 New Bern became the seat of Craven precinct. within r..ln':- n years e that date Eduard Moseley's survey showed four streets--Frcnt or Hater, Craven, P'Liddle, and an east -west street that today is eitber Pollock or Broad.

A first not in New Bern in 1737, and after 1746, met there regularly until afte the American Revolution, with the exception of the few years during which Governor Arthur Dobbs moved the seat of government to the Cape Fear. In 1749 the first printing press in North Carolina was established in New Bern. The printer, .James Davis, began in 1751 the first newspaper in the colony, the North -Carolina Gazette. New Bern, the most central of the North Carolina coastal settlements, was a natural center for government and trade; it was relatively accessible to the outside world by water and to interior settlements by river and over- land transportation. Governor Milliam Tryon firmly established New Bern as the colonial capital in 1765 when he began construction of the Governor's Palace. Tryon chose a site on the southwestern perimeter of the settlement and John Hawks from England as the architect. The boundaries selected for the New Barn Historic District correspond closely with the area indicated as being settled on C. J. Sauthier's 1769 may of the town. The section of Pollock Street west of the palace was "taken up' during the next two decades. Close to the confluence of the two rivers, clustered around the Anglican Church. at Middle and Pollock streets, the cotmnercial center of the town was developing. Printing press, stores, banks, and the municipal wharves were between the palace and the point where the rivers join. Commercial and residential structures traditionally coexisted on the river shores. The fine dwellings of merchants Are often coupled with the means of their income --wharves, warehouses, and offices --a situation which lasted until the twentieth century. In the decade following the construction of the Governor's Palace, Now Bern became a revolutionary center as well. The first publicly initiated assembly was called there on August 25, 17714, against the wishes of the governor; in accordance with the resolves of that Congress and those of a second popular assembly which met in New Bern on April 3, 1775, committees of safety for that town and Craven County and for other North Carolina jurisdic- tions were created. Iwo weeks later, with the arrival of nea of the Battle of Lexington, the local militia began drilling. The Americas! Revolution was underway in North Carolina, and the royal governor, in effect, became a prisoner in his own palace. The port of New Bern sheltered numerous privates s who operated continuously throughout the war. Early in 1777 the first state government under a new constitution was inaugurated in New Bern under Co,erno Richard Caswell. The assembly continued to meet there until April, 1780, when Governor Nash took his oath of office in the Governor's Palace. The palace was already in bad repair by that time anfl !filliam Hooper noted that it had "more the appearance of a neglected jail than anything else." The palace served various u..sos until 1798 (:in that year for instance it housed the New Born Acadomy), whom all but tie wings burned. After the bzrning of the palace, the land was opened for settlamDnt and quickly filled critl! houses; George Street was extended southward toward tho Trent Rivcr, GPI, `J:'.Y>A F onn 10-700.

The rivers and the trade they carried always had been a part of her livelihood, but they were to become her major means of support. Well endowed with dense pine forests in the surround- ing area, the tcnrn came to export vast quantities of lumber, hogshead staves, barrel heading, tar, pitch, and spirits of turpentine. In addition, New Bern was the funnel through which passed farm products like pork, corn, and peas. New Bern and her residents had been and continued more and more to participate in the triangular trade route between the Carolinas, the blest Indies (and the Iberian Coast), and New England. Although residents think of New Bern as a colonial town, the physical evidence remaining reflects a city that achieved its apex of prosperity and sophistication in the Federal era. The blocks filled out; in the area of the Neuse River civic and cultural amenities like the New Bern Academy and.the Masonic Temple and Theatre were constructed; Baptist, Methodist, Presbyterian, and Catholic congregations built churches.(That built by the Catholics -- St. Paul's --was the first in the state.) The shore of the Trent River dQvDlor as a tightly -packed commercial section; wharves and docks expanded; livery stables, restaurants, boarding houses,and stores accommodated both the resider and transient. The jagged shoreline still bears evidence of the slips and wharves which were fostered by water commerce and many early wharf area buildings remain as well. • Just as shipping played a large part in evolving the character of the area in the mid -eighteenth century, so did the railroad in the mid-rn'_netsenth The tracks of the Atlantic and North Carolina Railroad (now the Southern Railway) run through the district, down Hancock Street (referred to for many years as Railroad Avenue), and the station which brought freight and travello from the east and .rest was established here. The railroad ryas neither an interloper nor polluter as it might seem to many to be today, but an irdieati of the town's progress and prosperity. Just as tho wharfs, warehouses, and stores of the shippers had been an integral and welcome part of a residential - area a century before, so was the railroad in the 1850s. When Union forces occupied New Bern early in the Civil War (in April of• 1862), they established headquarters in two Neuse River mansions, the Slover- Bradham House and the Jones -Jarvis House. Other officers and enlisted men were billeted throughout the city. Union occupation affected the area little in an architectural sense except for the fact 'that they saved the city by extinguishing the fires set by the fleeing Confederates. When the restored government of North Carolina was authorized by President Lincoln, Edward Stauly, formerly of New Bern, was appointed governor, and he too established both his offices and residence along the Neuse. Actually, New Bern survived the war with little damage, except of course to family fortunes. The city entered its third era of intensive development in the deeadpc innediately preceding and after 1900; once again its base was lumber.

B. C (Continuation Sheet) ENTRY NUMBER DATE — -. Timberlands in the surrounding counties produced fine quality pine, gum, cypre oak, and other hardwoods which kept New Bern's lumber mills (sixteen in 1916) abundantly supplied. In addition, the city was a superior source for seafood, especially shell fish, and what was not consumed locally or shipped out was processed in several fertilizer factories. Limited amounts of cotton and tobacco filtered through New Bern but were vastly outweighed by truck crops distributed through several wholesale grocers. Two railroads and six steamshi companies carried freight and visitors to and from Now Berry and shipping by this time was centered almost exclusively on the Trent River. Building during this vital era produced a number of elaborate and ambitious domestic, insti= tutional, and commercial structures. The First Church of Christ, Scientist, was the first edifice constructed by that faith in North Carolina. The advent of World War II brought in swarms of armed service personnal attached to nearby Cherry Point Air Base. To accommodate the considerable overflow £ram Cherry Point, New Bernians opened their homes and divided other stately houses into apartments. Some of the alterations were sympathetically done, but in other cases buildings were mutilates d. In the 1940s Minnete (Mrs. Richard) Duffy inspired and initiated the movemant to reconstruct the governor's palace. Mrs. Maude Moore LathatR established two trust funds for the reconstruction. The actual construction, which began in the mid-1950s, necessitated the closing of George Street. Known as the Tryon Palace complex, the area includes the reconstructed palace; the Stevenson House, a restorad Federal era house museum; the Daves House, used for administrative offices; the Jones House, a guest house; an auditorium and the John Wright Stanly House, a Georgian style house muse o .

CONTI NUATION SHEET - ITEM NUMBER 7 PAGE 7 In March of 1982 Archaeological Research Consultants of Chapel Hill, N.C.', and Tidewater Atlantic Research of Washington, N.C., under contract to the Wilmington District, undertook an underwater investigation of the Efird Company property in New Bern, N.C. This survey took place in the waters of the Neuse River in an area immediately adjacent to the.New Bern Historic District, The area surveyed is owned by the Efird Company, New Bern, N.C., and the State of North Carolina.. A summary of the findings of the survey is presented below. A more complete description can be found in the report entitled "A Cultural Resources Survey of the Efird Company Property, New Bern, N.C." Examination of the proposed boat basin identified the remains of a timber frame and ballast cobble structure that covered roughly 50 percent of the area. From a point 40 feet east of a galvanized iron pipe at mean low water on the north property line a series of timbers, approximately 12 inches square, had been employed to construct a retaining bulkhead. The feature had been positioned to extend east 55 feet before joining a second segment of retaining bulkhead extending 45 feet to the south. At that point a third segment of retaining bulkhead was found to extend east for an additional 60 feet. Vertical butt scarfs were'employed in fashioning joints, and iron pins were used to both secure scarf joints and assure vertical integrity. Along the third segment additional timbers approximately 12 feet long and cut :y4a 6 inches by 8 inches, were found to have been positioned perpendicular to the east/west segment on centers of approximately 5 feet. Each was found to project north of the 60—foot section approximately 1S inches and extend south into ballast cobble and brick rubble concentrated south and west of each segment of the feature. Ballast cobble and brick rubble were observed to extend approximately 20 feet to the south and west of each segment. However, only random scatter was found to the north and east. Otherwise, the bottom surface was found to be free of cultural material. Form No. 10-300a Woo. 10.741 UNITED STA'fESDEPARTMENT OF•TkEINURIOR ORNP.5U360NIY.

CONTINUATION SHEET ITEM NUMBER 7 PAGE 8 Along that section of the project area south of the proposed boat basin and lying west of and adjacent to the Neuse River channel, a series of timber cribs approximately 10 feet square and 3 to 4 feet deep was found to have been positioned adjacent to the shore. The cribs, coostructed from timbers cut roughly 12 inches square, were located immediately inside or west of the line of abandoned pilings. Each crib was filled with a combination of ballast cobble and brick rubble to'within 18 inches of the water surface. Outside the cribs and pilings, the bottom surface was found to be free of cultural material with the exception of an occasional ballast cobble or brick fragment. Light-colored sediment in the area between the pilings and the channel shoulder was found to extend to a depth of more than 4 feet. Immediately north of the northernmost crib the remains of a wooden hull steam vessel were found. Approximately 30 feet of the stern lay exposed beyond the extent of modern rubble fill composing the present shoreline. Within the remains of an eliptically-shaped fantail, the rudder, rudder shaft and quadrant, and a four -blade, 4-foot diameter iron propeller were found immediately aft and east of the sternpost,. From the sternpost an iron propeller shaft extended west into the remains of the hull. Frames approximately 6 inches square and hull planking approximately 2 inches in thickness identified the extremities of the hull and provided an indication that the beam.was approximately 20 feet. -A Fo(m No. 10300a lRow. 10.74) UNITED STATES DEPARTMENT UN THE INTI:RIOR FOR NPS USE ONLY NATIONAL PARK SERVICE RECEIVED NATIONAL REGISTER OF HISTORIC PLACES INVENTORY --NOMINATION FORM DATE ENTERED Amendment to the New Bern Historic District, Craven County, N. C. - CONTINUATION SHEET _ ITEM NUMBER 8 PAGE 4 The bulkheads, cribs, and 19th century vessel contained in the area being added to the New Bern Historic District meet criteria c (embody the distinctive characteristics of'a type period or method of construction) and criteria d (have yielded or likely to yield information important in history). In addition the area containing these structures represent one of the last remaining areas of the New Bern Historic Waterfront. Structural evidence found in the area of the proposed boat basin and dock complex appears to be the remains of a wharf complex and associated slips. A brief survey of maps of New Bern dating from 1769 through 1924 indicates that the structure was not on the site prior to 1810 and was no longer in use by 1880. A plan of the town dated 1849 illustrates a waterfront configuration similar to that indicated by the remains of the wharf structure. A Civil War period plan indicates the presence of a wharf in the area but it does not conform to the configuration present on the plan of 1849. , The cribbing located to the south and adjacent to the Neuse River channel appears to have been constructed at the site at some time between the Civil War and 1880. Examination of available maps of the area indicates that the features may have been associated with the New Bern Manufacturing Company that was located on the site by 1880 and the grist and fertilizer company of E.H. and S.A. Meadows, which appears as early as 1888. .The configuration of the waterfront from 1880 until 1924 indicates that the cribbing could have served both firms as a wharf and dock structure. The remains of the steam vessel. identified during the survey can reliably be considered to date from the 19th century. While it is possible that the ship is associated with structures that appear on the 1849 map, it is also possible that the vessel could have been as with either New Bern Manufacturing or E.H. and J.A. Meadows Company later in the century. The position of the wreck indicates that the vessel was either -moored at its present location when it sank or was deliberately sunk at the site. In the case of the former, it is likely that both the vessel and the dock were no longer in active use or the steamer would have been raised to clear the slip or return it to service. If the vessel was deliberately sunk at the location, it would seem that either the slip was no longer in demand or the hull was to be employed to contain fill as part of an expanding wharf complex. The lack, of fill in the stern makes this unlikely. Form Na. 10.300A (Rev. 10.741 UNITED STATES DEPARTNIENTOFTHE INTERIOR PORNPS'USEONhY'`.' NA'(IONAtPAAXSERVICE - f RECEIVED. NATIONAL REGISTER OF HISTORIC PLACES INVENTORY- NOMINATION FORM OATE ENTERED Amendment to the New Bern Historic District, Craven County, N.C. CONTI NUAT;ON SHEET ITEM NUMBER 8 PAGE 5 The wreck contains information about the design and construction of what is %f likely a local vessel, only a superficial examination of marine architecture and ship construction source material is necessary to illustrate how little is known of vessels constructed in North Carolina and the southeastern United States. This absence of primary historical source data makes the remains of local, vessels particularly significant. The fact that the wreck represents a steam vessel dating possibly as early as the second quarter of the 19th century increases its value, as this was an important period in the development of steam technology. The propeller, for example, was invented in 1834. An early date for construction could mean that the vessel's powerplant and propulsion machinery represent an early example of steam engineering. While the location of the vessel must be considered an indication of its possible association with fourth quarter businesses previously identified, it is also possible that the ship could be associated with New Bern's Civil War history or have served as one of several ferries known to have operated out of the general area.prior to and after the Civil War.

Stocks Engineering is contracted with the Oakley Collier Architects for the civil engineering aspects of the design and permitting process. The proposed multi -level patio will increase the amount of impervious surface on the site and two infiltration basins are proposed to treat the increased impervious area. Stormwater Management Plan The onsite soil consists of loamy sand to sand. The soil is Seabrook -Urban land complex (A Soils) Soils information was obtained through the NRCS website: htp•//websoilsurvey.nres.usda.aov/app/ for Wake County. The site currently drains directly into the Trent River which is a tributary to the Neuse River. The proposed site improvements increase the onsite impervious area 2,274.28 SF. The site design provides two small infiltration basins that will treat 5,838.38 SF of total drainage area, 5,553.9 SF of which is impervious. The infiltration basins trap the 1.5 - INCH storm and allows the runoff to infiltrate the natural ground at a rate of 1.1 IN/HR. Post -development runoff is less than pre -development because of the addition of the infiltration basins. The impervious area that will drain into the existing stormwater control measures was reduced by 3,279.62 SF.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including fanners, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (hftp:/Avww.nres.usda.govtwps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (hftps://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/1 cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verity predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil RECEIVED MAR 0 2 2020 DCM-MHD CITY Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the RECEIVED survey area, they drew the boundaries of these bodies on aerial photographs and MAR 0 2 2020 DCM-MHD CITY Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, RECEIVED MAR 0 2 2020 11 DCM-MHD Crry Custom Soil Resource Report onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group (New Bern Riverfront Convention Center) Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (AID, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils RECEIVED have a moderate rate of water transmission. MAR 0 2 2020 15 I)CM-MHD CITY Custom Soil Resource Report Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (AID, BID, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Front Street New Bern, NC In -situ Infiltration Testing Dear Mr. Wilke, Raleigh - Geotech/CMT Lab 5400 Old Poole Road T 919.380.8750 Raleigh, NC 27610 GEOTECHNICAL ADDENDUM NO. 1 As requested, Stewart has completed infiltration testing for the above -referenced project. This letter describes the testing performed and resulting data. Infiltration testing was performed at two locations as shown on the attached plan. Infiltration testing was performed using a Guelph Permeameter, which is a field-testing device that measures the in -situ, steady-state rate of water recharge under a constant -head condition. The infiltration tests for both locations were performed in a 6 cm diameter hand auger boring advanced to depth of 12 inches below the current ground surface. Two tests were performed per location to allow averaging of the data. The average infiltration rates for locations I-1 and I-2 were 5.5 in/hr and 1.1 in/hr, respectively. The soil encountered at the test locations was fill material and visually -manually classified as Silty SAND (USCS Class: SM). The soil at I-2 appeared to have slightly more fines (slit/clay) than I-1. Since the near surface soil in this area is relatively recent fill, likely placed during construction of the Convention Center, the usual identifiers of the seasonal high water table (SHWT) were not present. However, the soil test borings performed during our subsurface exploration in May 2019 indicate that the groundwater was at a depth of 5 feet below the current ground surface in this portion of the site. The water table is expected to undergo tidal Fluctuation due to its proximity to the river and groundwater mounding likely occurs during periods of heavy rain at high tide stage. This being the case, it is reasonable to estimate the SHWT in this portion of the site is at or very near the current ground surface. We trust that this letter is responsive to your needs at this time. If you have any questions, please feel free to call me.

Project Description The existing New Bern Riverfront Convention Center is enlarging their outdoor patio space. Stocks Engineering is contracted with the Oakley Collier Architects for the civil engineering aspects of the design and permitting process. The proposed multi -level patio will increase the amount of impervious surface on the site and two infiltration basins are proposed to treat the increased impervious area. Stormwater Management Plan The onsite soil consists of loamy sand to sand. The soil is Seabrook -Urban land complex (A Soils) Soils information was obtained through the NRCS website: htto7//websoilsurvev nres usda gov/aoo/ for Wake County. The site currently drains directly into the Trent River which is a tributary to the Neuse River. The proposed site improvements increase the onsite impervious area 2,274.28 SF. The site design provides two small infiltration basins that will treat 5,838.38 SF of total drainage area, 5,553.9 SF of which is impervious. The infiltration basins trap the 1.5 - INCH storm and allows the runoff to infiltrate the natural ground at a rate of 1.1 IN/HR. Post -development runoff is less than pre -development because of the addition of the infiltration basins. The impervious area that will drain into the existing stormwater control measures was reduced by 3,279.62 SF.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (hftp://www.nres.usda.gov/wps/portal/nres/detail/soilstcontactusn cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character RECEIVED soil properties and the arrangement of horizons within the profile. After the soil MAR 0 2 2020 DCM-MHD CITY Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and RECEIVED MAR 0 2 2020 DCM-MHD CITY Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the RECEIVED development of resource plans. If intensive use of small areas is planned, however, MAR 0 8 ZOZO 11 DCM-MHD CITY Custom Soil Resource Report onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group (New Bern Riverfront Convention Center) Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils RECEIVED have a moderate rate of water transmission. MAR 0 2 2020 1s DCM-MHD CITY Custom Soil Resource Report Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. 16 RECEIVED MAR 0 2 2020 DCM-MHD CITY 3 617N M. 6TN Custom Soil Resource Report ti Map —Hydrologic Soil Group (New Bern Riverfront Convention Center) a (N QN 3V240 31 Ti 31M 31C ... 3 A H Map Sole:1:1,220 Mpi'6ed on Apoiea&(8.5"x 11')shee[ N Mess A 0 15 30 W 90 Feet 0 50 100 310 300 Map P<oJecbw: Web Maoax Car axrdn bes: WGS8d Edge Ba: UIM Zone 18N W(S801 17 3 617N I I 3 67N 314 314= 3 b REPEIVED MAR 0 2 2020 DCM-MHD CITE' MAPLEGEND Area of Interest (AOI) E] Area of Interest (AOI) Solis Soil Rating Polygons .

Front Street New Bern, NC In -situ Infiltration Testing Dear Mr. Wilke, Raleigh - Geotech/CMT Lab 5400 Old Poole Road T 919.380.8750 Raleigh, NC 27610 GEOTECHNICAL ADDENDUM NO. 1 As requested, Stewart has completed infiltration testing for the above -referenced project. This letter describes the testing performed and resulting data. Infiltration testing was performed at two locations as shown on the attached plan. Infiltration testing was performed using a Guelph Permeameter, which is a field-testing device that measures the in -situ, steady-state rate of water recharge under a constant -head condition. The infiltration tests for both locations were performed in a 6 cm diameter hand auger boring advanced to depth of 12 inches below the current ground surface. Two tests were performed per location to allow averaging of the data. The average infiltration rates for locations I-1 and I-2 were 5.5 in/hr and 1.1 in/hr, respectively. The soil encountered at the test locations was fill material and visually -manually classified as Silty SAND (USCS Class: SM). The soil at I-2 appeared to have slightly more fines (silt/clay) than I-1. Since the near surface soil in this area is relatively recent fill, likely placed during construction of the Convention Center, the usual identifiers of the seasonal high water table (SHWT) were not present. However, the soil test borings performed during our subsurface exploration in May 2019 indicate that the groundwater was at a depth of 5 feet below the current ground surface in this portion of the site. The water table is expected to undergo tidal fluctuation due to its proximity to the river and groundwater mounding likely occurs during periods of heavy rain at high tide stage. This being the case, it is reasonable to estimate the SHWT in this portion of the site is at or very near the current ground surface. We trust that this letter is responsive to your needs at this time. If you have any questions, please feel free to call me.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
