DIVISION OF ENVIRONMENTAL MANAGEMENT WATER QUALITY SECTION MEMORANDUM: f I TO: John Dorney FROM: Ron Ferrell SUBJECT: Mitigation Plan for Alcoke/CGW, Inc DATE: April 6, 1995 The following comments are submitted in response to the review of the subject document dated March 15, 1995. 1. The mitigation plan as submitted continues to be deficient in a number of areas and should not be accepted until the plan has been finalized. I can agree with the plan on a conceptual basis, however sufficient information has not been submitted to determine if the proposal has a reasonable chance of success. This mitigation proposal should not be treated any differently than plans submitted by any other applicant and should be held to the same standards used to evaluate other projects.. Outlined below are specific areas of concern that must be addressed prior to approval of this plan. 2. The stated goal of the project is to restore a wet hardwood flat on Rains soils. The location of the proposed reference forest ecosystem should be identified and the existing hydrology and vegetation of this area should f be documented with a particular emphasis of the herbaceous understory which are the most sensitive to changes in hydrology. If the herbaceous understory is dominated by species that are facultative or drier then the site is not acceptable as a reference site. Also, the functions lost and the functions to be restored should be identified. 3. Although the COE hydrology criteria is important in determining the f jurisdictional status of an area it should not be used to determine if hydrology has been restored. The reference hydrology should first be determined then the project site should be designed to establish that hydrology. 4. The water budget does not account for the loss of water through infiltration and deep seepage. Rains soils may have an infiltration rate that is sufficient to affect the hydrology on this site. Another factor that may affect the hydrology of this site is the presence of ditches in I i proximity to this site that will not be plugged/filled. No data has been presented on the direction of groundwater flow and the potential of nearby ditches to intercept this flow. 5. Water budget continued. No response was provided to the previous questions (memo dated 12/8/94) concerning the assumptions used in the water budget. Specifically the allowances for runoff, evapotranspiration, offsite runoff, evaporation and groundwater flow. 6. Previous comments concerning frequency of monitoring of hydrology and soils have not been addressed. 7. The comments concerning species to be planted have not been addressed. These issues must be addressed before this plan can be accepted. Also, when will the plantings occur. 8. Written verification from the USACOE must be submitted concerning the legality and acceptability of the conservation easement. alcoke/cgw.495 /mitigation Post-it' Fax Note 7671 To :10?? ?__ Cc i;-i'l prone M ?x k Dat?`Y .

Faz u I i D MIQfAIyDUM: ?- I ,16n-AL MANAG JTY SECTION TO: John Dorney FROM: Ron Ferrell,k_ SUBJECT: Mitigation Plan for Alcoke/CGW, Inc D ATF,- December $,, 1994 The following comment' are submitted in response to the review of the subject document dated November 15, 1994. 1 A description of the soil -types, vegetation and hydrology dated August 9, 1994 is referenced. I Flo not have this document. This document is supposed to conti.in a description of the wet hardwood flat area that will be used as the reference forest ecosysiem (RFE). Please have applicant provide me with a copy of this document. 2 A map (or maps) of the -mitigation site must be submitted which show the following information: 1) general location. of mitigation site; 2) location of drainage ditches and proposed plugs; 3) elevations; 4) direction of surface water and ground water flown; 5) predicted wetness of areas within site; 6) species to be planted in each area if areas of different wetness present on site; 6) location of overflow swales; location of monitoring wells and all permanent sample plots. ? 3. De-wribe how the hydrogeomorphology will be used to determine where species will be printed. (referenced on page 5) I 4. Species should be selected based on predicted wetness o? site and ordered from a reputable source. Nursery availability is not an acceptable criteria for determining the species to be planted. With the exception of Yellow Poplar I have no objection to the species selected (assuming that they are referring to Nyssa sylvatica var biflora) however it does not appear that any thought has been given to which species should be planted based on expected hydrology. The species selected. range from facultative to obligate which is OK if these ronditions exist on the site. Also, what is species composition of reference site? If refererce site has been logged and massaged they may need to locate a "pristine" site to determine species c:orAposition or DFT 08 1 q4 nl?: 96PM P. 2:2 consult the literature for descriptions of hardwood flats before they were all converted into lain forests. 5 What is the justification for plugging the ditches instead of filling the ditches in? How deep are the ditches on the site? Have the ditches penetrated any soil layers that restrict the downward movement of water? If so the ditches may have to be filled with some type of impprvious material. 6. Have the soils been evaluated for the presence of plow pans, hard pans or anything that may inl-ubit the growth of the trees? 7. Because the site has been actively farmed some provision should be mach to "rough" the site to increase the micro topographic relief. R What is the current depth to groundwater on the site? What is the predicted depth to groundwater after ditches have been plugged, i.e. how often during the growing season is the depth to groundwater expected to to 1efs than 12 inches. It would be useful to use 17RA1NMQT) to predict the hydrology of the site. 9. Provide explanation of how the numbers used in the water budget were determined, i.e. what is basis for using 10% of precipitation for runoff rate, etc. 10. Permanent sample plc,ts should be randomly selected throughout the site pric:?r to planting of -Irees. There should be a minimum of one 0.05 acre sample plot per acre unless it can be demonstrated that the site is so uniform in elevation ind wetness that this number of plots is not needed. 11. Specify the frequency of monitoring of hydrology and vegetation. Recommend that hydrology be monitored monthly during the first year and quarterly thereafter. Recommend that vegetation be monitored frequently during first growing season. Soils should be monitored in the permanent plots for the presence of indicators of hydrology. 12. An "as built" report should be submitted within 30 days of completion of planting of trees. 13. Remedial actions must t* taken to control nuisance vegetation which is defined as any species that is not planted. 14. All monitoring reports and requests to conduct remedial actions should also be sent to the Division of Environmental Management. i DEC OP '94 05:37PM s . .. P. 3%3 15. Vegetation success criteria should be 320 trees per acre that have survived for three full f70wing seasons. 16. 1 have no idea if the prc posed Conservation Easement is legal. It specifies the United Stages of America as the holder of the easement. Need to check with the ;lawyers can this one. ?1R-2q-35 THU 9:42 P. 01 ROBERT M. CHILES, P.E. INDEX 1.

IMPACTED AREA DESCRIPTION: The 30 acre site to be developed includes a wet pine flat that is located within the City of New Bern. The site is located in the Lawson Creek/Trent River Watershed and that discharges into the Trent River approximately one (1) mile upstream of the confluence of the Trent River and the Neuse River. The site is generally cleared of timber except for small pines along the abandoned railroad right of way just adjacent to the highway on the south. The site is bounded by commercial and retail development along U. S. highway 70, U. S. highway 17 and Glenburnie Road. The development will include placing fill on the Alcoke parcel, the CGW Inc. parcel and the extension of McCarthy Blvd. 4. MITIGATION AREA DESCRIPTION: The 72 Acre site that will provide the 60 acres of mitigation area is located off NCSR 1256 (Wintergreen Road) near Cove City, North Carolina. The site is located in the Core Creek Watershed which discharges Intothe Neuse River approximately 16 miles upstream of the confluence of the Trent River and the Neuse River in New Bern, North Carolina. The site is bounded on the North, South and West by woodland and on the East by agricultural development. The site has been previously converted by clearing and drainage from a hardwood wet flat to agricultural use. The mitigation plan for the site is to re-establish the wetland hydrology and vegetation thereon. The restoration will be concurrent with development work on the 30 acre site. 5. MITIGATION RATIO$ The development and fill at the 30 acre site on U. S. Highway 17 will be mitigated by restoration of the 72 acres at the Wintergreen Road site and 60 acres of this restored hardwood wet flat will provide the 2:1 mitigation ratio. 6. REFERENCE ECOSYSTEM: The Land Management Group, Inc., Wetland Classification Summary, dated August 9, 1994 provides descriptive relationship of the soil types, vegetation and hydrology at the development site and the mitigation site. In addition, the surrounding vegetation and soil profiles were noted for adjacent areas as reference. The wet hardwood flat area adjacent to the mitigation site will be utilized as reference during mitigation of the 72 acres. 4 ,I,I I { 7. SUCCES S CRITE RIA: r The subsurface hydrology of the mitigation site will be restored by filling the on site drainage in order to maintain a saturated soil condition within 12 inches of the surface, or ponded and flooded for at least 12.5% of the growing season under reasonable average climatic conditions. Vegetation will be re-established with a survival goal of 320 trees for acre after three (3) years. Final tree composition goal is that no more than 20% of any one hardwood species will dominate. 8. VEGETATION: The tree species to be planted will include the following. The exact mix and quantity of each species to be determined by nursery availability and soil test. The U. S. Dept. of Agriculture Forest Service General Technical Report SE-76 "Guide to Regeneration of Bottomland Hardwoods" will be utilized as reference in the final species selection. (a) Swamp Chestnut- Quercus michauxii (b) Water Oak - Quercus nigra (c) Willow Oak - Quercus phellos (d) Green Ash - Fraxinus pennsylvania (e) Cypress - Taxodium distichum (f) Yellow Popular- I-iriodendron tulipifcra (g) Black Gum - Nyssa aquatics (h) Black Gum - Nyssa sylvatica It is expected that a natural regeneration of loblolly pine and sweet gum will occur on the mitigation site. Mowing or chopping will be utilized if found necessary to eliminate excess competition to the selected species that are planted. The species selected will provide a habitat similar to that existing in the reference adjacent areas prior to logging. The initial planting will be 400 trees per acre under the direct supervision of qualified forestry professional. The seedling stock is to be obtained from a nursery located within 200 miles of the mitigation site. The stock shall be bare root, 1 year old, 12 to 18 inches high, 1 /4 inch or greater diameter root collar and with 4 or more lateral roots. Condition of this stock shall be monitored prior to and during planting to assure high survivability rate. The site distribution of species shall be based on soil fertility, species growth rates and hydrogeomorphology in individual portions of the mitigation site. 5 Sample plot for survival analysis shall be a minimum of one 0.05 acre sample plot per two (2) acres of the mitigation site. Sample plots shall be conducted in August/September each year until vegetation success criteria is met. 9. SOILS: The mitigation site soil is to be sampled and analyzed to determine PH, lime and fertilizer requirements before planting of tree seedlings. Corrective measures will be taken as found necessary to promote the successful regeneration of the wetland hardwoods. Site soil fertility and genetic differences within species can influence the ability of trees to tolerate flooding and this pre-planting site study will assist in selection of species. Soils on the mitigation site are mapped as Rains and on a site examination confirms the mapping. The site is currently part under cultivation and the remainder used as cattle pasture. The mitigation site consists of farmland that was cleared and converted approximately eight (8) years previous. The site drainage is southwest to Northeast with three (3) main lead ditches and two (2) laterals. The fields had not been leveled or crowned and no sub-surface drainage has been constructed. The two (2) debris windrows (30'x 500' approximately) located in the Southwest pasture portion of the site are to remain to provide transition habitat for wildlife. The windrows are partially overgrown and are not to be disturbed. The existing drainage system is to be plugged at ditch intersections or outlets with minimum length of 50 feet. Each plug is to be cut down along the centerline to provide a swale overflow 0.5 feet below adjacent original grade. The banks of the ditches will be peeled back with a dozer or motor grader to partially fill the flow line of the ditch inverts creating periodic standing water condition within the resulting depression along the filled ditch line. 6 10. HYDROLOGY: The mitigation site selection was based upon the existing small variations in topography typifying a wet hardwoods flat. The location of the site is adjacent to a true Carolina Bay pocosin located to the Southwest and having a slightly higher elevation (+3 feet more or less). The seep effect of ground water from the adjacent bay combined with precipitation will provide the primary hydrologic input. Analysis of uncleared timberlands adjacent to the mitigation indicates that the mitigation site priorto conversion supported wet hardwood flat vegetation. 11. WATER BUDGET: The Water Budget for the mitigation site follows and indicates sufficient water will be available to restore the hydrology necessary to support the wetland hardwood vegetation. <1.> Precipitation (P) (a) Average annual precipitation Craven County, N. C. Is 54.5 inches (b) Precipitation inflow =54.5" x 72 ac = 327 Ac.ft/yr. 12 <2.> Runoff (R) (a) Surface runoff from the Mitigation Site will be restricted by grading and filling existing ditches. (b) Allowance for Runoff due to storm events will be 10% of the annual precipitation. (c) Groundwater Outflow =0.10 x 54.5 x 72 = 32.7 Ac.-Ft/Yr. 12 <3.> Groundwater Flow (G) (a) Groundwater flow from the mitigation site will be limited due to elimination of adjacent ditches and the rains soils. (b) Allowance for groundwater flow will be 20% of the annual precipitation. (c) Groundwater Outflow = 0.20 x 54.5 x 72 = 65.4 Ac.-Ft/Yr. 12 7 t a- <4.> Evaporation (E) (a) Free water evaporation will be limited to periodic ponding within the mitigation site. (b) Allowance for evaporation will be 41 inches per year over 10 acres of ponded water (c) Evaporation Outflow = 41 x 10 =34.2 Ac.-Ft/Yr. 12 (d) Free water evaporation should cease to occur as full revegetation is established on the mitigation site. <5.> Evapotranspiration (ET) (a) Allowance for evapotranspiration rates forthe mitigation site when vegetation is fully established will be 70% of the annual free water evaporation rate of 41 inches per year. (b) Evapotranspiration Outflow = 0.70 x 41 x 72 = 172.2 Ac.-Ft/Yr. 12 <6.> Offsite Runoff (OR) (a) The sandridge west of the mitigation site is expected to provide a combined surface runoff during storm events and groundwater flow into the mitigation site that will enter the mitigation site hydrology. The area contributing to this runoff will be approximately 50 acres and an allowance for runoff equaling 20% of the annual precipitation will exit this area. (b) Offsite Runoff - 0.20 x 54.5 x 50 = 45.4 Ac.-Ft/Yr. 12 <7.> Wetland Soil Storage (S) (a) (b) The excess water available for establishing and maintaining the wetland hardwood vegetation will be stored in the rains soils. Soil storage = S=P+OR-R-G-E-ET S=327 + 45.4 - 32.7 - 65.4 -34.2 -172.2 S= 67.9 Ac.-Ft./Yr. 8 il r g l: (a) The water budget indicates that sufficient excess water will be available within the mitigation site to support establishment of wetland hardwood vegetation. (b) Provisions for allowing offsite runoff of excess water will be a swale spillway constructed in each drainage ditch plug. These swales shall be initially also plugged with small earthen check dams approximately 10 feet wide and will later be opened manually with shovels should added drainage be found desirable when the initial surface water supply is found to be in excess of that required for seedlings. In apparent lowest areas bedding will be desirable for Immature plantings and is to be accomplished as necessary to raise the roots sufficiently for the planted trees to thrive. 12. The groundwater hydrology and surface ponding will be monitored by periodic visual observations, hand borings and monitoring wells installed per WRP Technical Note HY-1A- 3.1 dated August 1993. The slight variations in topography throughout the mitigation site are expected to maintain wetland hydrology in a portion of the site during dry periods and these areas will be documented to verify suitable conditions to allow the selected species of trees to thrive. Should some area indicate excessive soil moisture or flooding, limited drainage may be restored to direct the water to drier areas on site after consultations with Corps of Engineers Representatives. 13. PROJECT MONITORING: The overall responsibility for this mitigation project will be: Mr. Joe Alcoke 3305 Clarendon Blvd. New Bern, North Carolina 28560 (919) 638-6161 tell 7--, CGW Inc. Mr. Calvin Wellons P. O. Box 1018 Morehead City, N. C. 28557 (919) 726-2151 The responsibility for actual development of the mitigation site will be delegated by the owners to various engineers, biologists, foresters, and contractors as necessary during the three (3) years required for successful completion of the mitigation. 14. REPORTS: The progress of the mitigation shall be documented by annual reports over the three year monitoring period developed during August - September of each year as the project progresses. The annual report shall be submitted within 30 days of monitoring and shall include the following: Photographs Sample Plot Data Well Data (if applicable) Problems/Resolution Upon determination that the mitigation plan has been successfully implemented a final "As-Built" report will be prepared and issued. This report shall include the following: Final Elevations Photographs Sample Plot Locations Well Data (if applicable) Problems/Resolution Planting Design/Sample Plot Data General Discussion 10 i 15. REMEDIAL ACTION: Any deviations from this plan will be coordinated with and approved by the Corps of Engineers. Unsuccessful vegetation survival will be corrected by re-planting of the same or similar species or by alternate species that may be determined by soil/hydrology conditions. The hydrology within the site shall be monitored and areas within the site determined to be too wet or too dry are to be corrected by modification of the surface water/groundwater drainage. Vandalism or animal depredation shall be monitored and corrective action taken as found necessary. 16. FINAL DISPOSITION OF MITIGATION SITE Upon successful completion of the development of the 72 acre site to a wet hardwood flat the property will remain in the ownership of the principals until such time as a transfer of ownership is deemed suitable. Upon transfer of ownership, the deeds will contain a conservation easement or deed restriction to maintain the site as a wet hardwood flat. Donation or sale of the site to education or conservation organizations will include similar conservation easement or deed restrictions. 11 { }' f??. ? it ? 4 ? - = s x.G 1 F tt 17.

The species hick is OK if these )ecies composition of ;ed and managed they may species composition or DEC OR- '94 05:96R,' P.2/3 consult the literature for descriptions of hardwood flats before they were all converted into pine forests. 5. What is the justification For plugging the ditches instead of filling the ditches in? How deep are the ditches on the site? Have the ditches penetrated any soil layers that restrict the downward movement of water? If so the ditches xnay have to be filled with some type of impervious material. 6. Have the soils been evaluated for the presence of plow pans, hard pans or anything that may inl'dbit the growth of the trees? 7. Because the site has been actively farmed some provision should be made to "rough" the site. to increase the micro topographic relief. 8. What is the current depth to groundwater on the site? What is the predicted depth to groundwater after ditches have been plugged, i.e. how often during the growing season is the depth to groundwater expected to be less than 12 inches. It would be useful to use ORAINMOD to predict the hydrology of the site. 9. Provide explanation of how the numbers used in the water budget were determined, i.e. what is basis for using 10% of precipitation for runoff rate, etc. 10. Permanent sample plots should be randomly selected throughout the site prior to planting of trees. There should be a minimum of one 0.05 acre sample plot per acre unless it can be demonstrated that the site is so uniform in elevation imd wetness that this number of plots is not needed. 11. Specify the frequency of monitoring of hydrology and vegetation. Recommend that hydrology be monitored monthly during the first year and quarterly thereafter. Recommend that vegetation be monitored frequently during first growing season. Soils should be monitored in the permanent plots for the presence of indicators of hydrology. 12. An "as built" report should be submitted within 30 days of completion of planting of trees. 13. Remedial actions must be taken to control nuisance vegetation which is defined as any species that is not planted. 14. All monitoring reports and requests to conduct remedial actions should also be sent to the Division of Environmental Management. DEC 08 '94 35:37PM P. 3i3 15. Vegetation success criteria should be 32D trees per acre that have survived for three full ;rowing seasons. 16. I have no idea if the prcposed Conservation Easement is legal. It specifies the United States of America as the holder of the easement. Need to check with the lawyers on this one. Fo `- I T y ROBERT M. CHILES,.P.E.

My comments relating to other matters included in this memo follow in the order listed in reference (c). 1. Enclosure (1) is the Land Management Report describing the mitigation site. 2. Enclosure (2) shows the site location. Enclosure (3) is a topographic map of the site showing the relative elevations, locations of existing ditches and the windrows and other existing vegetation. MECHANICAL, CIVIL, AND MARINE ENGINEERING MARINE HYDROGRAPHIC AND LAND SURVEYS COMMERCIAL, INDUSTRIAL, MARINE AND RAILROAD FACILITIES DESIGN FORENSIC ENGINEERING AND FAILURE ANALYSIS BOUNDARY SURVEYS AND MAPPING SERVICE Mr. John Dorney Page 2 March 15, 1995 Enclosure (4) is an overlay of the topographic map showing direction of surface and ground flow. As is evident from the elevations, surface flows are nil except in the ditches. The near surface groundwater flow is expected to exist as shown. Enclosure (5) is an overlay of the topographic map showing the proposed ditch plugs and overflow swales. The plugs and swales are subject to modification as the mitigation is developed based upon monitoring well data. Enclosure (6) is an overlay of the topographic map showing location of ground water monitoring wells and permanent sample plots. 3. The analysis of the interaction surface hydrology with the surface water and soil types throughout the site will be utilized in the final selection of particular plant species to be planted at individual portion within the mitigation site. Data collected from monitoring wells and observation of the ditch flows will be utilized for the analysis prior to planting. 4. The species selection will only be from reputable sources since the survival goal of planted trees is the basis for the success criteria of the mitigation. Nursery availability must be considered for selection of species since we cannot plant what is not available within the 200 mile radius of the mitigation site. However, the species selection will be from the list contained within the mitigation plan and the nursery order will be for planting seeds of the species selected for later transplant to the site. These listed species were selected after review of literature and consultation with registered foresters as to historic species to be found in wet hardwood flats. 5. Plugging ditches was selected as the preferred method of modification of the drainage in order to minimize mechanical disturbances within the site and to allow later modification if excess surface standing water endangers the planted seedlings. Soils investigation to date indicate that the existing ditches have not penetrated restrictive soil layers that would prevent subsurface outflow of surface drainage. This will be monitored during the mitigation process and sealing of ditch inverts will be completed if found necessary. i 14 Mr. John Dorney Page 3 March 15, 1995 6. The site has been in agricultural use about 15 years or less and soil borings have not indicated a hardpan that would inhibit growth of selected species. 7. Our intent is to initially disc the entire site prior to initiating the tree planting and to periodically disc areas between the plantings to limit unwanted competition if necessary. 8. The current depth of the groundwater on the site is seasonal and varies between 12 inches and 24 inches. It is our professional judgment based upon experience with similar sites that plugging the existing drainage will result in groundwater hydrology that will support the wetland vegetation to be planted. 9. The water budget was prepared using published data and best professional judgment. The 10% surface runoff was included as a nominal entry in the budget and can be varied by changes in the outlet swales as is found necessary. 10. The sample plot of one 0.05 acre sample plot per two (2) acres of the mitigation site is considered sufficient due to the topography of the site (see enclosure (3)). 11. The plan (paragraph 8 page 6) specifies that the sample plots shall be monitored in August/September of each year. The hydrology will be monitored and reported in conjunction with these sample plots. Additional random vegetation and hydrology monitoring will be conducted throughout the development of the mitigation in order to assist in the success of the plan. 12. An "as built" report of the completion of planting can be prepared. 13. Paragraph (8) page (5) of the mitigation specifies mowing or chopping to eliminate excess competition and control nuisance vegetation. 14. Correspondence relative to the mitigation will be sent to N.C.DEM. 15. The success criteria of the mitigation plan is 320 trees per acre. l I I Mr. John Domey Page 4 March 15, 1995 16. The U. S. Army Corps of Engineers has agreed with the conservation Easement. I trust that the enclosed report and maps, along with the above comments will be sufficient for your approval of the mitigation plan. Our clients expect to begin construction in June 1995 but closure of the development property is currently on hold until such time as the mitigation plan is approved by your office. Your early action will be appreciated. Very truly yours, Robert M. Chiles, P.E. RMC:jrf cc: Joe Alcoke CGW Inc. i- i ' I I I I • I i i ? ?

Si?ld? Bob Chiles P.O. Box 3496 New Bern, N.C. Dear Bob: 28564-3496 August 9, 1994 99"aa >4 2..V A.A CIA. OW 3805 WIto"W& dwmw Wi&d'V&X'.NW M03 As requested on 8/4/94, I examined and documented the soils, vegetation and apparent hydrology on the t 30 acre Alcoke Development site in New Bern and the t 71 acre mitigation site near Cove City. The purpose of this examination was to determine whether or not the development site was a Pocosin wetland and to classify the wetland that existed prior to agricultural activity on the mitigation site. Most of the project site was cleared in the recent past which removed all native vegetation and root mat. The site was replanted with Loblolly Pine which is now 3-4' high. The other vegetation in this replanted area consists of Woolgrass, Dog Fennell, Beak Rush, Wire Grass, Blue Stem, Eastern Baccharus, Wax Myrtle and various other successional species. The northeast end of the project area has recently been clear cut. This activity has removed all standing vegetation leaving the tree stumps only. Vegetation around this clear cut area consists of Loblolly Pine, Sweet Bay, Bracken Fern, Wire Grass, Red Bay, Red Maple, Sweet Gum, Vaccinium and Black Gum. Soil profiles were documented at two locations on the project site (profiles 3 and 4). Profile 3 as shown in the enclosed photos was augered near the center of the cleared, replanted area. Profile 4 was augered near the edge of the clear cut area to the northeast. All soil descriptions were to a depth of 48". Soil descriptions noted on the project site at profile sites 3 and 4 are as follows: Soil Profile 3 A 0-8" 10 yr 2/1 fine sandy loam Btg 1 8-17" 10 yr 5/2 heavy sandy loam Btg 2 17-31" 10 yr 6/1 light sandy clay loam, 10 yr 6/5 mottles Cg 31-48" 10 yr 7/1 sandy loam 3 2 Soil Profile 4 A 0-7" 10 yr 2/1 fine sandy loam Bw 7-15" 10 yr 4/2 fine sandy loam Btg 1 15-36" 10 yr 6/1 light sandy clay Btg 2 36-42" 10 yr 5/2 sandy clay loam, Bcg 42-48" 10 yr 6/2 light sandy clay loam, 10 yr 6/5 mottles 10 yr 6/5 mottles loam Watertable levels were noted as being greater than 48" below the surface at soil profile 3 and 38" at soil profile 4. Pocosins typically are characterized by vegetation which includes Pond Pine, Loblolly Bay, Sweet Bay and Red Bay with a dense layer of evergreen shrubs which include Fetterbush, Titi, Inkberry and Smilax. Of course, these vegetation types can be found in various types of wetland systems. Vegetation at the project site has obviously been altered to the point where it could no longer be considered a functioning Pocosin community - if it ever was. The remaining surrounding vegetation as noted does not indicate a true Pocosin blend. The overstory of Loblolly Pine and the absence of Pond Pine and Loblolly Bay indicates a slightly higher better drained inclusion within the mapped Torhunta soil unit. The Pocosin soils are organic or very poorly drained acid mineral soils which feature a black fine sandy loam A horizon generally 10 to 24" thick. Organic Pocosin soils are most commonly known for their thick 0 horizons ranging from 16 to 108". The documented soil profiles on the project site show only a 7 to 8" thick A horizon which is far short of the norm for a mineral Pocosin soil. Again, the project site is displaying characteristics of a better drained inclusion within the mapped soil unit. Based on the noted vegetation types and soil profiles, the project site would not be characterized as a Pocosin. The higher degree of diversity within the surrounding vegetation and the non- characteristic soil profiles indicate that this site was a poorly drained wooded flat with possible micro-topographic drainage-ways of very poorly drained soils. With the past clearing activities on this property and surrounding drainage impacts, it is highly unlikely that even if a Pocosin wetland existed on this site in the past, that restoring one at this point would not be a realistic endeavor. The mitigation site consists of prior converted farmland currently being used for soybean production and cattle grazing. A small wooded section'is along the farm entrance road and wooded land is present off the tract boundaries. Soils here were mapped as Rains which is a poorly drained soil common to regional wetlands in an i 3 unaltered state. Vegetation in the small wooded area on the tract consisted of Red Maple, Loblolly Pine, Sweet Gum, Water Oak, Sweet Bay, Red Bay, Switchcane, Fetterbush, Sweet Pepperbush and Cinnamon Fern. Soil profiles were documented at two locations on the mitigation tract (Profiles 1 and 2). Profile one was augered approximately 60' from the edge of the soybean field in the western end of the tract. Profile 2 was augured within the small wooded area off the entrance road at the eastern end of the tract. Soil descriptions were to a depth of 48". Soil descriptions noted on the mitigation site at profile sites 1 and 2 are as follows: Soil Profile 1 AP 1 0-6" 10 yr 2/1 fine sandy loam, many uncoated grains Ap 2 6-12" 10 yr 6/2 fine sandy loam Btg 1 .12-26" 10 yr 6/1 sandy clay loam, 10 yr 6/8 mottles Btg 2 26-40 10 yr 7/1 sandy clay loam, 10 yr 6/8 mottles Soil P rofile 2 A 0-8" 10 yr 2/1 fine sandy loam Btg 1 8-20" 10 yr 6/1 light sandy clay loam, 10 yr 6/7 mottles Btg 2 20-30" 10 yr 5/1 sandy clay loam, 10 yr 6/7 m ottles Btg 3 30-42" 10 yr 6/1 sandy clay loam, 10 yr 6/8 m ottles Cg 42-48" 10 yr 5/1 light sandy clay loam, 10 yr 6/7 mottles Watertable levels wer e noted at 30" below the surface at Profile 1 and 36" at Pro file 2. The native vegetation and soils on the mitigation tract are typical of those found on broad inter-stream wooded flats in this region. The soil profiles closely correlate to the mapped rains soil unit. Most undisturbed rains soils areas are indeed flat wooded wetlands. Restoring this prior converted tract to wetland is a logical and workable undertaking. Plugging the existing ditches should successfully restore wetland hydrology. Watertable levels here were already higher than the project site. Not far from the western corner of the tract is a large Carolina Bay. Water was noted seeping to the surface of a woods road just off the tract. Bay vegetation could be seen around this corner of the property which also indicates a healthy level of groundwater nearby. With the proper number and mix of plantings along with the restored site hydrology, this tract should perform well as mitigated acreage. 4 Please contact me to discuss any questions you may have at any time.

THE APPLICANTS PROPOSE TO MITIGATE 60 ACRES FOR THIS PROJECT BY RESTORATION OF A 72 ACRE TRACT ADJACENT TO A LARGE POCOSIN WITHIN THE NEUSE RIVER/CORE CREEK WATERSHED, OFF SR 1256, NORTH OF COVE CITY, CRAVEN COUNTY, NORTH CAROLINA. The following description of the work is taken from data provided by the applicant and from observations made during an onsite visit by a representative of the Corps of Engineers. Plans submitted with the application show approximately 100,000 cubic yards of fill material is proposed to be placed into approximately 25 acres of wetlands located above the headwaters of Wilson Creek, to facilitate-the development of retail stores and to connect McCarthy Blvd from US 17 to Glenburnie Road. Of this proposed project site, approximately 21.6 acres of the Alcoke property were cleared in 1991 by unauthorized mechanized landclearing. This property previously was vegetated with Red maple, Lobolly bay, greenbriar, low gallberry, tall gallberry, blueberry, fetterbush, and waxmyrtle. The entire 21.6 acres was revegetated in 1992. The adjoining C.G.W., Inc. property is currently vegetated with the same species. The purpose of the work is to facilitate the development of retail stores and to complete the connection of McCarthy Blvd. Plans showing the work are included with this public notice. To mitigate for the wetland impacts, the applicants propose to return a 72 acre, prior converted tract to wetlands, utilizing 60 acres as mitigation for this project. The site is currently farmland and pasture, having drainage ditches surrounding the site. The soils are classified as Rains. An inspection of the site on 24 May 1994, found hydrology ranging from 8 to 18 inches below the surface. Approximately 75? of the property is currently planted in soybeans. The remaining 25t is being used as pasture for cattle grazing. The applicants propose to plug the ditches to completely restore wetland hydrology. Once the depth of the restored seasonal high water table, fertility and drainage throughout the site has been determined, individual hardwood species will be selected on the basis of site suitability, and in . r -2- accordance with the Corps current migitation guidelines. The exact species to be planted have yet to be determined. One or two disking treatments may be necessary during the first growing season following planting to reduce competition for the seedlings. The applicant has determined that the proposed work is consistent with the North Carolina Coastal Zone Management Plan and has submitted this determination to the North Carolina Division of Coastal Management for their review and concurrence. This proposal shall be reviewed for the applicability of other actions by North Carolina agencies such as: a. The issuance of a Water Quality Certification under Section 401 of the Clean Water Act by the North Carolina Division of Environmental Management. b. The issuance of a permit to dredge and/or fill under North Carolina General Statute 113-229 by the North Carolina Division of Coastal Management. C. The issuance of a permit under the North Carolina Coastal Area Management Act (LAMA) by the North Carolina Division of Coastal Management or their delegates. d. The issuance of an easement to fill or otherwise occupy State-owned submerged land under North Carolina General Statute 143-341(4), 146-6, 146-11, and 146-12 by the North Carolina Department of Administration and the North Carolina Council of State. e. The approval of an Erosion and Sedimentation Control Plan by the Land Quality Section, North Carolina Division of Land Resources, pursuant to the State Sedimentation Pollution Control Act of 1973 (NC G.S. 113 A-50-66). The requested DA permit will be denied if any required State or local authorization and/or certification is denied. No DA permit will be issued until a State coordinated viewpoint is received and reviewed by this agency. Recipients of this notice are encouraged to furnish comments on factors of concern represented by the above agencies directly to the respective agency, with a copy furnished to the Corps of Engineers. This application is being considered pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for'the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this worksite is not registered property or property listed as being eligible -3- for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer, based on available information, is not aware that the proposed activity will affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (in accordance with Executive order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments -4- are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Generally, the decision whether to issue this DA permit will not be made until the North Carolina Division of Environmental Management (DEM) issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The DEM considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the DA permit serves as application to the DEM for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Environmental Management, Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. The North Carolina Division of Environmental Management plans to take final action in the issuance of the Clean Water Act certification on or after July 8, 1994. All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Environmental Management, Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before June 27, 1994, Attention: Mr. John Dorney. Written comments pertinent to the proposed work, as outlined above, will be received in this office, Attention: Mr. Norm Sanders, until 4:15 p.m., July 11, 1994, or telephone (919) 975-3025. 4•'?1 0 ?b /ao' C THIS H/?p eEVUCeo) Ko?.O In o s t G L O C I 0 n v 6NEET I OFF- C? ?r r?

Bob Chiles P.O. Box 3496 New Bern, N.C. 28564-3496 Dear Bob: August 9, 1994 Yid& 14 AOp.A4 =5 vaputda dwMae 9W6i*StM' .W MW3 As requested on 8/4/94, I examined and documented the soils, vegetation and apparent hydrology on the t 30 acre Alcoke Development site in New Bern and the t 71 acre mitigation site near Cove City. The purpose of this examination was to determine whether or not the development site was a Pocosin wetland and to classify the wetland that existed prior to agricultural activity on the mitigation site. Most of the project site was cleared in the recent past which removed all native vegetation and root mat. The site was replanted with Loblolly Pine which is now 3-4' high. The other vegetation in this replanted area consists of Woolgrass, Dog Fennell, Beak Rush, Wire Grass, Blue Stem, Eastern Baccharus, Wax Myrtle and various other successional species. The northeast end of the project area has recently been clear cut. This activity has removed all standing vegetation leaving the tree stumps only. Vegetation around this clear cut area consists of Loblolly Pine, Sweet Bay, Bracken Fern, Wire Grass, Red Bay, Red Maple, Sweet Gum, Vaccinium and Black Gum. Soil profiles were documented at two locations on the project site (profiles 3 and 4). Profile 3 as shown in the enclosed photos was augered near the center of the cleared, replanted area. Profile 4 was augered near the edge of the clear cut area to the northeast. All soil descriptions were to a depth of 48". Soil descriptions noted on the project site at profile sites 3 and 4 are as follows: Soil Profile 3 A 0-8" 10 yr 2/1 fine sandy loam Btg 1 8-17" 10 yr 5/2 heavy sandy loam Btg 2 17-31" 10 yr 6/1 light sandy clay loam, 10 yr 6/5 mottles Cg 31-48" 10 yr 7/1 sandy loam ?ik4 i Soil Profile 4 S.>????'2 A 0-7" 10 yr 2/1 fine sandy loam Bw 7-15" 10 yr 4/2 fine sandy loam Btg 1 15-36" 10 yr 6/1 light sandy clay loam, 10 yr 6/5 mottles Btg 2 36-42" 10 yr 5/2 sandy clay loam, 10 yr 6/5 mottles Bcg 42-48" 10 yr 6/2 light sandy clay loam Watertable leve ls were noted as being gre ater than 48" below the surface at soil profile 3 and 38" at soil profile 4. Pocosins typically are characterized by vegetation which includes Pond Pine, Loblolly Bay, Sweet Bay and Red Bay with a dense layer of evergreen shrubs which include Fetterbush, Titi, Inkberry and ?t Smilax. Of course, these vegetation types can be found in various types of wetland systems. Vegetation at the project site has obviously been altered to the point where it could no longer be considered a functioning Pocosin community - if it ever was. The remaining surrounding vegetation as noted does not indicate a true Pocosin blend. The overstory of Loblolly Pine and the absence of Pond Pine and Loblolly Bay indicates a slightly higher better drained inclusion within the mapped,Torhunta soil unit. The Pocosin soils are organic or very poorly drained acid mineral soils which feature a black fine sandy loam A horizon generally 10 to 24" thick. Organic Pocosin soils are most commonly known for their thick O horizons ranging from 16 to 108". The documented soil profiles on the project site show only a 7 to 8" thick A horizon which is far short of the norm for a mineral Pocosin soil. Again, the project site is displaying characteristics of a better drained inclusion within the mapped soil unit. Based on the noted vegetation types and soil profiles, the project site would not be characterized as a Pocosin. The higher degree of diversity within the surrounding vegetation and the non- characteristic soil profiles indicate that this site was a poorly drained wooded flat with possible micro-topographic drainage-ways of very poorly drained soils. With the past clearing activities on this property and surrounding drainage impacts, it is highly unlikely that even if a Pocosin wetland existed on this site in the past, that restoring one at this point would not be a realistic endeavor. The mitigation site consists of prior converted farmland currently being used for soybean production and cattle grazing. A small wooded section'is along the farm entrance road and wooded land is present off the tract boundaries. Soils here were mapped as Rains which is a poorly drained soil common to regional wetlands in an 3 unaltered state. Vegetation in the small wooded area on the tract consisted of Red Maple, Loblolly Pine, Sweet Gum, Water Oak, Sweet Bay, Red Bay, Switchcane, Fetterbush, Sweet Pepperbush and Cinnamon Fern. Soil profiles were documented at two locations on the mitigation tract (Profiles 1 and 2). Profile one was augered approximately 60' from the edge of the soybean field in the western end of the tract. Profile 2 was augured within the small wooded area off the entrance road at the eastern end of the tract. Soil descriptions were to a depth of 48". Soil descriptions noted on the mitigation site at profile sites 1 and 2 are as follows: Soil Profile 1 Ap 1 0-6" 10 yr 2/1 fine sandy loam, many uncoated grains Ap 2 6-12" 10 yr 6/2 fine sandy loam Btg 1 .12-26" 10 yr 6/1 sandy clay loam, 10 yr 6/8 mottles Btg 2 26-40 10 yr 7/1 sandy clay loam, 10 yr 6/8 mottles Soil Profile 2 A 0-8" 10 yr 2/1 fine sandy loam Btg 1 8-20" 10 yr 6/1 light sandy clay loam, 10 yr 6/7 mottles Btg 2 20-30" 10 yr 5/1 sandy clay loam, 10 yr 6/7 mottles Btg 3 30-42" 10 yr 6/1 sandy clay loam, 10 yr 6/8 mottles Cg 42-48" 10 yr 5/1 light sandy clay loam, 10 yr 6/7 mottles Watertable lev els wer e noted at 30" below the surface at Profile 1 and 36" at Pro file 2. The native vegetation and soils on the mitigation tract are typical of those found on broad inter-stream wooded flats in this region. The soil profiles closely correlate to the mapped rains soil unit. Most undisturbed rains soils areas are indeed flat wooded wetlands. Restoring this prior converted tract to wetland is a logical and workable undertaking. Plugging the existing ditches should successfully restore wetland hydrology. Watertable levels here were already higher than the project site. -from the western corner of the tract is a large Carolina Bay.'k' ater was noted seeping to the surface of a woods road just off the tract. Bay vegetation could be seen around this corner of the property which also indicates a healthy level of groundwater nearby. With the proper number and mix of plantings along with the restored site hydrology, this tract should perform well as mitigated acreage. 4 Please contact me to discuss any questions you may have at any time.

GAL- ?`N PI,,,)A 2C-1 ?NIS DIVISION OF ENVIRONMENTAL MANAGEMENT WATER QUALITY SECTION TO: John Dorney FROM: Ron Ferrell SUBJECT: Mitigation Plan for Alcoke/CGW, Inc DATE: April 6, 1995 The following comments are submitted in response to the review of the subject document dated March 15, 1995. 1. The mitigation plan as submitted continues to be deficient in a number of areas and should not be accepted until the plan has been finalized. I can agree with the plan on a conceptual basis, however sufficient information has not been submitted to determine if the proposal has a reasonable chance of success. This mitigation proposal should not be treated any differently than plans submitted by any other applicant and should be held to the same standards used to evaluate other projects.. Outlined below are specific areas of concern that must be addressed prior to approval of this plan. 2. The stated goal of the project is to restore a wet hardwood flat on Rains soils. The location of the proposed reference forest ecosystem should be identified and the existing hydrology and vegetation of this area should be documented with a particular emphasis of the herbaceous understory which are the most sensitive to changes in hydrology. If the herbaceous understory is dominated by species that are facultative or drier then the site is not acceptable as a reference site. Also, the functions lost and the functions to be restored should be identified. 3. Although the COE hydrology criteria is important in determining the jurisdictional status of an area it should not be used to determine if hydrology has been restored. The reference hydrology should first be determined then the project site should be designed to establish that hydrology. 4. The water budget does not account for the loss of water through infiltration and deep seepage. Rains soils may have an infiltration rate that is sufficient to affect the hydrology on this site. Another factor that may affect the hydrology of this site is the presence of ditches in proximity to this site that will not be plugged/filled. No data has been presented on the direction of groundwater flow and the potential of nearby ditches to intercept this flow. 5. Water budget continued. No response was provided to the previous questions (memo dated 12/8/94) concerning the assumptions used in the water budget. Specifically the allowances for runoff, evapotranspiration, offsite runoff, evaporation and groundwater flow. 6. Previous comments concerning frequency of monitoring of hydrology and soils have not been addressed. 7. The comments concerning species to be planted have not been addressed.

My comments relating to other matters included in this memo follow in the order listed in reference (c). 1. Enclosure (1) is the Land Management Report describing the mitigation site. 2. Enclosure (2) shows the site location. Enclosure (3) is a topographic map of the site showing the relative elevations, locations of existing ditches and the windrows and other existing vegetation.

As is evident from the elevations, surface flows are nil except in the ditches. The near surface groundwater flow is expected to exist as shown. Enclosure (5) is an overlay of the topographic map showing the proposed ditch plugs and overflow swales. The plugs and swales are subject to modification as the mitigation is developed based upon monitoring well data. Enclosure (6) is an overlay of the topographic map showing location of ground water monitoring wells and permanent sample plots. 3. The analysis of the interaction surface hydrology with the surface water and soil types throughout the site will be utilized in the final selection of particular plant species to be planted at individual portion within the mitigation site. Data collected from monitoring wells and observation of the ditch flows will be utilized for the analysis prior to planting. 4. The species selection will only be from reputable sources since the survival goal of planted trees is the basis for the success criteria of the mitigation. ursery availability must be considered for selection of species since we N b c cannot plant what is not available within the 200 mile radius of the mitigation (V `E./o0(3site. However, the species selection will be from the list contained within the ?? ®?`SP l mitigation plan and the nursery order will be for planting seeds of the species selected for later transplant to the site. These listed species were selected after review of literature and consultation with registered foresters as to historic species to be found in wet hardwood flats. 5. Plugging ditches was selected as the preferred method of modification of the drainage in order to minimize mechanical disturbances within the site and to allow later modification if excess surface standing water endangers the planted seedlings. Soils investigation to date indicate that the existing ditches have not penetrated restrictive soil layers that would prevent subsurface outflow of surface drainage. This will be monitored during the mitigation process and sealing of ditch inverts will be completed if found necessary. Mr. John Dorney Page 3 March 15, 1995 6. The site has been in agricultural use about 15 years or less and soil borings have not indicated a hardpan that would inhibit growth of selected species. 7. Our intent is to initially disc the entire site prior to initiating the tree planting and to periodically disc areas between the plantings to limit unwanted competition if necessary. 8. The current depth of the groundwater on the site is seasonal and varies between 12 inches and 24 inches. It is our professional judgment based upon experience with similar sites that plugging the existing drainage will result in groundwater hydrology that will support the wetland vegetation to be planted. 9. The water budget was prepared using published data and best professional judgment. The 10% surface runoff was included as a nominal entry in the budget and can be varied by changes in the outlet swales as is found necessary. 10. The sample plot of one 0.05 acre sample plot per two (2) acres of the mitigation site is considered sufficient due to the topography of the site (see enclosure (3)). 11. The plan (paragraph 8 page 6) specifies that the sample plots shall be N? z?> 7" monitored in August/September of each year. The hydrology will be monitored and reported in conjunction with these sample plots. Additional random vegetation and hydrology monitoring will be conducted throughout the development of the mitigation in order to assist in the success of the plan. N u 12. An "as built" report of the completion of planting ;fin be prepared. 13. Paragraph (8) page (5) of the mitigation specifies mowing or chopping to eliminate excess competition and control nuisance vegetation. 14. Correspondence relative to the mitigation will be sent to N.C.DEM. 15. The success criteria of the mitigation plan is 320 trees per acre. Mr. John Dorney Page 4 March 15, 1995 16. The U. S. Army Corps of Engineers has agreed with the conservation Easement. - 5c-6N,T I trust that the enclosed report and maps, along with the above comments will be sufficient for your approval of the mitigation plan. Our clients expect to begin construction in June 1995 but closure of the development property is currently on hold until such time as the mitigation plan is approved by your office. Your early action will be appreciated. Very truly yours, L W-? Robert M. Chiles, P.E. RMC:jrf cc: Joe Alcoke CGW Inc. DIVISION OF ENVIRONMENTAL MANAGEMENT WATER QUALITY SECTION TO: John Dorney FROM: Ron Ferrel f e?? SUBJECT: Mitigation Plan for Alcoke/CGW, Inc DATE: December 8,1994 The following comments are submitted in response to the review of the subject document dated November 15, 1994. 1. A description of the soil types, vegetation and hydrology dated August 9, 1994 is referenced. I do not have this document. This document is supposed to contain a description of the wet hardwood flat area that will be used as the reference forest ecosystem WE). Please have applicant provide me with a copy of this document. 2. A map (or maps) of the mitigation site must be submitted which show the following information: 1) general location of mitigation site; 2) location of drainage ditches and proposed plugs; 3) elevations; 4) direction of surface water and ground water flows; 5) predicted wetness of areas within site; 6) species to be planted in each area if areas of different wetness present on site; 6) location of overflow swales; location of monitoring wells and all permanent sample plots. 3. Describe how the hydrogeomorphology will be used to determine where species will be planted. (referenced on page 5) 4. Species should be selected based on predicted wetness of site and ordered from a reputable source. Nursery availability is not an acceptable criteria for determining the species to be planted. With the exception of Yellow Poplar I have no objection to the species selected (assuming that they are referring to Nyssa sylvatica var biflora) however it does not appear that any thought has been given to which species should be planted based on expected hydrology. The species selected range from facultative to obligate which is OK if these conditions exist on the site. Also, what is species composition of reference site? If reference site has been logged and managed they may need to locate a "pristine" site to determine species composition or consult the literature for descriptions of hardwood flats before they were all converted into pine forests. 5. What is the justification for plugging the ditches instead of filling the ditches in? How deep are the ditches on the site? Have the ditches penetrated any soil layers that restrict the downward movement of water? If so the ditches may have to be filled with some type of impervious material. 6. Have the soils been evaluated for the presence of plow pans, hard pans or anything that may inhibit the growth of the trees? 7. Because the site has been actively farmed some provision should be made to "rough" the site to increase the micro topographic relief. 8. What is the current depth to groundwater on the site? What is the predicted depth to groundwater after ditches have been plugged, i.e. how often during the growing season is the depth to groundwater expected to be less than 12 inches. It would be useful to use DRAINMOD to predict the hydrology of the site. 9. Provide explanation of how the numbers used in the water budget were determined, i.e. what is basis for using 10% of precipitation for runoff rate, etc. 10. Permanent sample plots should be randomly selected throughout the site prior to planting of trees. There should be a minimum of one 0.05 acre sample plot per acre unless it can be demonstrated that the site is so uniform in elevation and wetness that this number of plots is not needed. 11. Specify the frequency of monitoring of hydrology and vegetation. Recommend that hydrology be monitored monthly during the first year and quarterly thereafter. Recommend that vegetation be monitored frequently during first growing season. Soils should be monitored in the permanent plots for the presence of indicators of hydrology. 12. An "as built" report should be submitted within 30 days of completion of planting of trees. 13. Remedial actions must be taken to control nuisance vegetation which is defined as any species that is not planted. 14. All monitoring reports and requests to conduct remedial actions should also be sent to the Division of Environmental Management. 15. Vegetation success criteria should be 320 trees per acre that have survived for three full growing seasons. 16. I have no idea if the proposed Conservation Easement is legal. It specifies the United States of America as the holder of the easement. Need to check with the lawyers on this one. P 5 S w t ? (-J? I Z-- Glyn,.ti seouvw - o P Ai- i s ?-•?3 h t?E? s ?S s ?r???

IMPACTED AREA DESCRIPTION: The 30 acre site to be developed includes a wet pine flat that is located within the City of New Bern. The site is located in the Lawson Creek/Trent River Watershed and that discharges into the Trent River approximately one (.1:Jrt?ile upstream of the confluence of the Trent River and the Neuse River. The site is generally cleared of timber except for small pines along the abandoned railroad right of way just adjacent to the highway on the south. The site is bounded by commercial and retail development along U. S. highway 70, U. S. highway 17 and Glenburnie Road. The development will include placing fill on the Alcoke parcel, the CGW Inc. parcel and the extension of McCarthy Blvd. 4. MITIGATION AREA DESCRIPTION: The 72 Acre site that will provide the 60 acres of mitigation area is located off NCSR 1256 (Wintergreen Road) near Cove City, North Carolina. The site is located in the Core Creek Watershed which discharges into the Neuse River approximately 16 miles upstream of the confluence of the Trent River and the Neuse River in New Bern, North Carolina. The site is bounded on the North, South and West by woodland and on the East by agricultural development. The site has been previously converted by clearing and drainage from a hardwood wet flat to agricultural use. The mitigation plan for the site is to re-establish the wetland hydrology and vegetation thereon. The restoration will be concurrent with development work on the 30 acre site. 5. MITIGATION RATIO: The development and fill at the 30 acre site on U. S. Highway 17 will be mitigated by restoration of the 72 acres at the Wintergreen Road site and 60 acres of this restored hardwood wet flat will provide the 2:1 mitigation ratio. 6. REFERENCE ECOSYSTEM: The Land Management Group, Inc., Wetland Classification Summary, dated August 9, 1994 provides descriptive relationship of the soil types, vegetation and hydrology at the development site and the mitigation site. In addition, the surrounding vegetation and soil profiles were noted for adjacent areas as reference. The wet h__ardwaodftta-rea adjacent to the mitigation site will be utilized as reference during mitigation of the 72 acres. t-d 4 7. SUCCESS CRITERIA: The subsurface hydrology of the mitigation site will be restored by filling the on site drainage in order to maintain a saturated soil condition within 12 inches of the surface, or ponded and flooded for at least 12.5% of the growing season under reasonable average climatic conditions. Vegetation will be re-established with a survival goal of 320 trees for acre after three (3) years. Final tree composition goal is that no more than 20% of any one hardwood species will dominate. aap /ate wm vA s, RAVaP A-, 3 r?5 8.

Mowing or chopping will be utilized if found necessary to eliminate excess competition to the selected species that are planted. The species selected will provide a habitat similar to that existing in the reference adjacent areas prior to logging. The Initial planting will be 400 trees per acre under the direct supervision of qualified forestry professional. The seedling stock is to be obtained from a nursery located within 200 miles of the mitigation site. The stock shall be bare root, 1 year old, 12 to 18 inches high, 1/4 inch or greater diameter root collar and with 4 or more lateral roots. Condition of this stock shall be monitored prior to and during planting to assure high survivability rate. The site distribution of species shall be based on soil fertility, species growth rates and hydrogeomorphology in individual portions of the mitigation site. 5 ?. i. ?? Samplq?plot for survival analysis shall be a minimum of one 0.05 acre sample plot per two (? acr s of the mitigation site. Sample plots shall be conducted in August/SepteMer each year until vegetation success criteria is met. 9. SOILS: The mitigation site soil is to be sampled and analyzed to determine PH, lime and fertilizer requirements before planting of tree seedlings. Corrective measures will be taken as found necessary to promote the successful regeneration of the wetland hardwoods. Site soil fertility and genetic differences within species can influence the ability of trees to tolerate flooding and this pre-planting site study will assist in selection of species. Soils on the mitigation site are mappe as Rains of d on a site examination confirms the mapping. The site is currently part under cultivation and the remainder used as cattle pasture. The mitigation site consists of farmland that was cleared and converted approximately eight (8) years previous. The site drainage is southwest to Northeast with three (3) main lead ditches and two (2) laterals. Th_efield orcNwned and no sub-surface drain ge has been constructed. The two (2) debris windrows (30'x 500' approximately) located in the Southwest pasture portion of the site are to remain to provide transition habitat for wildlife. The windrows are partially overgrown and are not to be disturbed. The existing drainage system is to be plugged at ditch ante wc:ti ons or outlets with ---- - minimum length of 50 feet. Each plug is to be cut down along the centerline to provide a swale overflow 0.5 feet below adjacent original grade. The banks of the ditches will be peeled back with a dozer or motor grader to partially fill the flow line of the ditch inverts creating periodic standing water condition within the resulting depression along the filled ditch line. 6 10. HYDROLOGY: The mitigation site selection was based upon the existing small variations in topography cdW flat. The location of the site is adjacent to a true Carolina Bay pocosin located to the Southwest and having a slightly higher elevation (+3 feet more or less). The seep effect of ground water from the adjacent bay combined with precipitation will provide the primary hydrologic input. Analysis of uncleared timberlands adjacent to the mitigation indicates that the mitigation site prior to conversion supported wet hardwood flat vegetation. 11. WATER BUDGET: The Water Budget for the mitigation site follows and indicates sufficient water will be available to restore the hydrology necessary to support the wetland hardwood vegetation. <1.> Precipitation (P) (a) Average annual precipitation Craven County, N. C. is 54.5 inches (b) Precipitation inflow =54.5" x 72 ac = 327 Ac.ft/yr. 12 <2.> Runoff (R) (a) Surface runoff from the Mitigation Site will be restricted by grading and filling existing ditches. (b) Allowance for Runoff due to storm events will be 10% of the annual precipitation. (c) Groundwater Outflow =0.10 x 54.5 x 72 = 32.7 Ac.-Ft/Yr. 12 <3.> Groundwater Flow (G) (a) Groundwater flow from the mitigation site will be limited due to elimination of adjacent ditches and the rains soils. (b) Allowance for groundwater flow will be 20% of the annual precipitation. (c) Groundwater Outflow = 0.20 x 54.5 x 72 = 65.4 Ac.-Ft/Yr. 12 7 <4.> Evaporation (E) Qoao,? V o (a) Free water evaporation will be limited to periodic ponding within the mitigation site. (b) Allowance for evaporation will be 41 inches per year over 10 acres of ponded 1 „I water ?L (c) Evaporation Outflow = 41 x 10 =34.2 Ac.-Ft/Yr. 12 (d) Free water evaporation should cease to occur as full revegetation is established on the mitigation site. <5.> Evapotranspiration (ET) (a) Allowance for evapotranspiration rates forthe mitigation site when vegetation is fully established will be 70% of the annual free water evaporation rate of 41 inches per year. (b) Evapotranspiration Outflow = 0.70 x 41 x 72 = 172.2 Ac.-Ft/Yr. 12 <6.> Offsite Runoff (OR) (a) The sandridge west of the mitigation site is expected to provide a combined surface runoff during storm events and groundwater flow into the mitigation site that will enter the mitigation site hydrology. The area contributing to this runoff will be approximately 50 acres and an allowance for runoff equaling 20% of the annual precipitation will exit this area. (b) Offsite Runoff - 0.20 x 54.5 x 50 = 45.4 Ac.-Ft/Yr. 12 <7.> Wetland Soil Storage (S) (a) The excess water available for establishing and maintaining the wetland hardwood vegetation will be stored in the rains soils. (b) Soil storage = S=P+OR-R-G-E-ET S=327 + 45.4 - 32.7 - 65.4 -34.2 -172.2 S= 67.9 Ac.-Ft./Yr. 8 (a) The water budget indicates that sufficient excess water will be available within the mitigation site to support establishment of wetland hardwood vegetation. (b) Provisions for allowing offsite runoff of excess water will be a swale spillway constructed in each drainage ditch plug. These swales shall be initially also plugged with small earthen check dams approximately 10 feet wide and will later be opened manually with shovels should added drainage be found desirable when the initial surface water supply is found to be in excess of that 9-1 required for seedlings. Inapparent lowest areas bedding will be desirable forw 115 immature plantings and is to be accomplished as necessary to raise the rooter sufficiently for the planted trees to thrive. 12. HYDROLOGY MONITORING: The groundwater hydrology and surface ponding will be monitored by periodic visual observations, hand borings and monitoring wells installed per WRP Technical Note HY-1 A- 3.1 dated August 1993. The slight variations in topography throughout the mitigation site are expected to maintain wetland hydrology in a portion of the site during dry periods and these areas will be documented to verify suitable conditions to allow the selected species of trees to thrive. Should some area indicate excessive soil moisture or flooding, limited drainage may be restored to direct the water to drier areas on site after consultations with Corps of Engineers Representatives. ??.- 13.
