Rindner, PLLC. Subject: SAW -2017-02345; Pre -Construction Notification for NWP 18 & 29 for the Twin Lakes Site, Weddington, Union County. Ms. Higgins and Messrs. Roden -Reynolds, Johnson, and Hamstead, Enclosed is a request for a Nationwide Permit #'s 18 & 29 for the approximate 97 -acre site known as the Twin Lakes site located northwest of the intersection of Beulah Church Rd and Waxhaw Indian Trail Road in Weddington, NC. The site is a proposed residential development and consists of five streams, six wetlands, and two open water ponds. A preliminary jurisdictional determination was submitted on August 27, 20187 (SAW -2017-02345). Please refer to the Jurisdictional Determination section for information on onsite surface waters. As shown on the attached exhibits, the proposed project will include permanent impacts to one intermittent stream for a road crossing and one wetland for a sanitary sewer installation. Overall impacts to site surface waters associated with the proposed development were limited through site selection location, design, location/orientation of the proposed lots, associated parking areas and access routes. Total permanent impacts proposed are to 0.008 acres of wetland (Wetland O) and 65 linear feet of intermittent stream (Stream A). Charlotte Office: www.wetlands-epg.com Asheville Office: 10612-D Providence Rd. 1070 Tunnel Rd., Bldg. I PMB 550 Suite 10, PMB 283 Charlotte, NC 28277 Asheville, NC 28805 (704)904-2277 1 len. ri ndner@wetlands-epg.com Wetlands and Environmental Planning Group Leonard S. Rindner. PLLC. Efforts of impact minimization were implemented during the design to preserve the existing channel hydrology and limit adverse effects to existing, onsite habitat. This project is proposed as a `low impact development' with less than 24% impervious surface overall. Directional boring is proposed for two additional sewer crossings to avoid additional impacts to streams and wetlands. The pond will be used for stormwater detention but not treatment. The applicant has demonstrated substantial avoidance and minimization efforts in which 97% of the 2,366 linear feet of streams and 99 % of the 1.13 acres of wetlands onsite will be avoided on the project. The single road crossing is proposed where an existing 60 -ft long serviceable culvert is located. The NCDOT is requiring this road to meet the requirements of a "Connector" with a minimum width of 35' and has requested that retaining walls not be used. Within these constraints, impacts have been minimized by moving the sidewalks as close the road as possible and using 2:1 slopes from the top of the headwalls. Temporary impacts for dewatering and construction access will be restored to original conditions as detailed in the stabilization plan included. The sanitary sewer installation below the existing dam was originally proposed as an aerial crossing but this was rejected by Union County Public Works. Due to the elevations of the tie-in sanitary sewer, it is not possible to bore under the wetlands at this location. Union County Public Works agreed to a compromise whereby the proposed sewer line can be placed behind the dam with a minimum amount of fill placed over the pipe along the dam to meet local ordinances. This results in a small impact to the wetland at this location. One other sewerline crossing will require a temporary open cut that will be restored to original conditions as detail on the plans. Elsewhere, directional boring is proposed wherever possible to avoid additional impacts. This project setting is in a relatively rural area along the outskirts of the 8 -digit watershed and is not subject to the same development pressure as other areas in this HUC. Due to the relatively small amount of impact to the intermittent stream and relatively low -quality wetland, no mitigation for these impacts are proposed. Please see the North Carolina Wetland Assessment Method (NCWAM) form attached for further details. Also enclosed is a copy of our Threatened/Endangered Species Evaluation for the site. No listed species were identified within the project area and we believe that there will be no effect on listed species or their critical habitat as designated under Section 7 of the Endangered Species Act. Please refer to the Threatened and Endangered Species Evaluation Section for additional details on the terrestrial species evaluation.

Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Due to the location of the on site streams and wetlands, opportunities to avoid these areas were limited. Impacts to site surface waters associated with the proposed development were limited through site selection location, design, location/orientation of the proposed lots and access routes. The only proposed road crossing is at the location of a previously installed culvert for an access trail unpaved trail. Headwalls and 2:1 slopes will be used to minimize the crossing width and avoid use of riprap. Sewer crossings will be conducted via bores wherever practicable. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Construction techniques will implement approved erosion control methods to avoid/minimize impacts to onsite/adjacent offsite receiving conveyances. At stream A the NCDOT required a minimum crossing width of 35' and no retaining walls, so impacts are minimized by grading at 2:1 slopes from the headwalls. At Wetland O, Union Co. would not allow an aerial crossing. A small amount of wetland is being graded and filled only for sewer installation and not to aid in dam stability - the dam conditions are stable and will not be compromised by the sewer installation (dam safety letter is included). 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.

(version 4.11) NC WAM FIELD ASSESSMENT FORM Evidence of stressors affecting the assessment area (may not be within the assessment area) Please circle and/or make note on the last page if evidence of stressors is apparent. Consider departure from reference, if appropriate, in recent past (for instance, within 10 years). Noteworthy stressors include, but are not limited to the following. • Hydrological modifications (examples: ditches, dams, beaver dams, dikes, berms, ponds, etc.) • Surface and sub -surface discharges into the wetland (examples: discharges containing obvious pollutants, presence of nearby septic tanks, underground storage tanks (USTs), hog lagoons, etc.) • Signs of vegetation stress (examples: vegetation mortality, insect damage, disease, storm damage, salt intrusion, etc.) • Habitat/plant community alteration (examples: mowing, clear -cutting, exotics, etc.) Is the assessment area intensively managed? ❑ Yes ® No Regulatory Considerations -Were regulatory considerations evaluated? ®Yes ❑No If Yes, check all that apply to the assessment area. ❑ Anadromous fish ❑ Federally protected species or State endangered or threatened species ❑ NCDWR riparian buffer rule in effect ❑ Abuts a Primary Nursery Area (PNA) ❑ Publicly owned property ❑ N.C. Division of Coastal Management Area of Environmental Concern (AEC) (including buffer) ❑ Abuts a stream with a NCDWQ classification of SA or supplemental classifications of HQW, ORW, or Trout ❑ Designated NCNHP reference community ❑ Abuts a 303(d) -listed stream or a tributary to a 303(d) -listed stream What type of natural stream is associated with the wetland, if any? (check all that apply) ❑ Blackwater ® Brownwater ❑ Tidal (if tidal, check one of the following boxes) ❑ Lunar ❑ Wind ❑ Both Is the assessment area on a coastal island? ❑ Yes ® No Is the assessment area's surface water storage capacity or duration substantially altered by beaver? ❑ Yes ® No Does the assessment area experience overbank flooding during normal rainfall conditions? ® Yes ❑ No Ground Surface Condition/Vegetation Condition — assessment area condition metric Check a box in each column. Consider alteration to the ground surface (GS) in the assessment area and vegetation structure (VS) in the assessment area. Compare to reference wetland if applicable (see User Manual). If a reference is not applicable, then rate the assessment area based on evidence an effect. GS VS ❑A ❑A Not severely altered ®B ®B Severely altered over a majority of the assessment area (ground surface alteration examples: vehicle tracks, excessive sedimentation, fire -plow lanes, skidder tracks, bedding, fill, soil compaction, obvious pollutants) (vegetation structure alteration examples: mechanical disturbance, herbicides, salt intrusion [where appropriate], exotic species, grazing, less diversity [if appropriate], hydrologic alteration) 2. Surface and Sub -Surface Storage Capacity and Duration — assessment area condition metric Check a box in each column. Consider surface storage capacity and duration (Surf) and sub -surface storage capacity and duration (Sub). Consider both increase and decrease in hydrology. A ditch s 1 foot deep is considered to affect surface water only, while a ditch > 1 foot deep is expected to affect both surface and sub -surface water. Consider tidal flooding regime, if applicable. Surf Sub ❑A ❑A Water storage capacity and duration are not altered. ❑B ❑B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation). ®C ®C Water storage capacity or duration are substantially altered (typically, alteration sufficient to result in vegetation change) (examples: draining, flooding, soil compaction, filling, excessive sedimentation, underground utility lines). 3.

It can be found on the Matthews NC USGS Topographic Quadrangle Map; latitude is 35.0220 N, longitude is 80.6981 W. The site is a mosaic of disturbed forest cover, agricultural fields, and open water lakes. There is a large overhead power line bisecting the northern section of the site. The topography is gently to moderately sloped with the elevation ranging from 600 to 650 ft. (Figure 1).

Rindner, PLLC. Tarin Lakes - Threatened / Endangered / Protected Species Evaluation Two plant species with federal protection are listed as potentially occurring in Union County: • Schweinitz's Sunflower (Helianthus schweinitzit), listed as Federally Endangered, is typically found in open habitats which historically have been maintained by wildfires and grazing bison and elk herds. Now most occurrences are limited to roadsides, woodland and field edges, and utility rights-of-way (ROW). • Michaux's Sumac (Rhus michauxii), listed as Federally Endangered, requires habitat of sandy forests and woodland edges. This species requires periodic fire as a part of its ecology. Two animal species with federal protection are listed as potentially occurring in Union County: • Bald Eagle (Haliaeetus leucocephalus), protected by the Bald and Golden Eagle Protection Act, typically inhabits forested areas near large bodies of open water such as lakes, marshes, seacoasts and rivers, where there are suitable fish populations and tall trees for nesting and roosting. Carolina Heelsplitter (Lasmigona decorata), listed as Federally Endangered, is restricted to cool, clean, well -oxygenated water. Stable, silt- free stream beds are required for this species. Typically, stable areas occur where the stream banks are well -vegetated with trees and shrubs. RESULTS: The site is a mosaic of disturbed forest cover, agricultural fields, semi -open scrub/shrub, transitional areas, and open water lakes. The site appears to have been managed as a hunting and fishing reserve in part. The large agricultural fields have most recently been planted in soybeans. The lakes have mostly wooded buffers dominated by Loblolly Pines (Pinus taeda). The eastern part of the site is covered by disturbed mixed hardwood forest that is laced by old road and trail cuts and shooting lanes. There is a large overhead power line bisecting the northern section of the site with scrub/shrub thickets. Parts of these areas appear to have been bushogged. The disturbed mixed hardwoods are dominated by White Oak (Quercus alba), with American Ash (Fraxinus americana), Northern Red Oak (Quercus rubra), Southern Red Oak (Quercus falcata), Black Oak (Quercus velutina), Mockernut Hickory (Carya tomentosa), Sweet Gum (Liquidambar styraciflua), and Tulip Poplar (Liriodendron tulipifera var. tulipifera). Subcanopy trees present are Wetlands and Environmental Planning Group Leonard S. Rindner, PLLC. Tarin Lakes - Tht•eatened / Endangered / Protected Species Evaluation American Beech (Fagus grandifolia), Sourwood (Oxydendrum arboreum), Red Maple (Acer rubrum var. rubrum), Red Cedar (Juniperus virginiana), Flowering Dogwood (Cornus florida), Persimmon (Diospyros virginiana), Black Gum (Nyssa sylvatica), Black Cherry (Prunus serotina), Redbud (Cercis canadensis), and American Holly (Ilex opaca). The sparse shrub layer includes Blueberry (Vaccnium sp.), and Chinese Privet (Ligustrum sinense). Vines present are Japanese Honeysuckle (Lonicera japonica), Catbrier (Smilax spp.), Virginia Creeper (Parthenocissus quinquefolia), Muscadine (Vitis rotundifolia), and Poison Ivy (Toxicodendron radicans). The herb layer includes Christmas Fern (Polystichum acrostichoides), and Japanese Stiltgrass (Microstegium vimineum). The large power line and the open corridors of dirt roads and shooting lanes have a mix of grass and forb dominated cover interspersed with thickets of scrub/shrub vegetation dominated by Blackberries (Rubus spp.), and Composites (Asteraceae). Parts of these areas appear to have been bushogged. Other typical species in these areas and also in the transitional areas include Broomsedge (Andropogon virginiana), Russian Olive (Elaeagnus umbellate), Chinese Privet (Ligustrum sinense), Smooth Sumac (Rhus glabra), Groundsel Tree (Baccharis halimifolia). Johnson Grass (Sorghum halepense), Plume Grass (Erianthus contortus), Sericea Lespedeza (Lespedeza cuneata), Pokeweed (Phytolacca americana), Rabbit Tobacco (Gnapthalium obtusifolium), Tickseed (Coreopsis major), Ragweed (Ambrosia artemisiifolia), Goldenrod (Solidago sp.), Beggars Ticks (Desmodium sp.), and Thoroughwort (Eupatorium sp.). Part of the roadside along Beulah Church Road has been recently regraded, matted, and seeded as part of ongoing road improvements. The rest of the roadside has been recently mowed and is dominated by Fescue turf grass (Festuca sp.), and common weedy and transitional species including Johnson grass, Sericea Lespedeza, Broomsedge, Purple Top (Tripsacum dactyloides), Dock (Rumex spp.), Ragwort (Packera sp.) Goldenrod and Dogfennel (Eupatorium capillifolium). Threatened & Endangered/Protected Species Results • All potential habitats for Schweinitz's Sunflower and Michaux's Sumac along the roadside corridor and woods edges were closely examined and neither of these species was present. There is no bald eagle habitat on site, and no eagles or eagle's nests were observed. • The on-site streams do not have the habitat characteristics required to support populations of the Carolina Heelsplitter. Based on existing documentation, Carolina Heelsplitter populations have not been previously Wetlands and Environmental Planning Group Leonard S. Rindner. PLLC. Tarin Lakes - Threatened / Endanlgered / Protected Species Evaluation identified within this basin. No individuals were observed during the survey nor would any be expected on-site. RECOMMENDATIONS: Based on the site investigation and the review of available data, WEPG did not identify any protected species occurring on the subject property. No further investigation of the presence of protected species on this site is recommended at this time. Respectfully submitted, i Lisa R.

V) 4-J N E U O w Supporting Documents Low Density Residential Subdivisions with Curb Outlet Swales Deed Restrictions & Protective Covenances In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246, the Stormwater Management Regulations, deed restrictions and protective covenants are required for Low Density Residential Subdivisions with curb outlet swales, where lots will be subdivided and sold. Deed restrictions and protective covenants are necessary to ensure that the development maintains a "built -upon" area consistent with the applicable regulation governing the density level. I, Dennis W. Moser, MAI acknowledge and affirm by my signature below, that I will cause the following deed restrictions and protective covenants to be recorded for Twin Lakes to the sale of any lot: prior The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number as issued by the Division of Water Quality under the Stormwater Management Regulations. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. The covenants pertaining to storm water may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Water Quality. 6. The maximum allowable built -upon area per lot is 6,585 square feet. This allotted amount includes any built -upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, and coquina, but does not include raised, open wood decking, or the water surface of swimming pools. 7. In the case of a lot within CAMA's regulated AEC, where the Division of Coastal Management calculates a different maximum allowable built -upon area for that lot than is shown herein, the governing maximum built -upon area for that lot shall be the most restrictive of the two. 8. This project proposes a curb outlet system. Each designated curb outlet swale shown on the approved plan must be maintained at a minimum of 100' long with 5:1 (H:V) side slopes or flatter, have a longitudinal slope no steeper than 5%, carry the flow from a 10 year storm in a non-erosive manner, and maintain a dense vegetated cover. 9. Filling in or piping of any vegetative conveyances (ditches, swales, etc.) associated with the development except for average driveway crossings, is strictly prohibited by any persons. 10. Each lot will maintain a 30* foot wide vegetated buffer between all impervious areas and surface waters. 11. All roof drains shall terminate at least 30* foot from the mean high water mark of surface waters. 12. Filling in, piping or altering any designated 5:1 curb outlet swale associated with the development is prohibited by any persons. *50 foot for projects located in the 20 coastal counties.

Graham Street Charlotte, North Carolina 28202 RE: Cloer Dam Union County State Dam ID: UNION -062 Dear Mr. Stewart: ROY COOPER Govemor MICHAEL S. REGAN Secretary WILLIAM E. TOBY VINSON, JR. Interim Director A request for jurisdictional determination for the above referenced dam was received in this office on May 30, 2018. Land Quality Section personnel from the Mooresville Regional Office conducted an inspection of the existing dam site on June 8, 2018. Based on observations made during the site inspection and a review of the information submitted with your request, our office has determined that a Class B intermediate hazard classification is presently warranted. Based on a review of the provided drawings and information, the proposed dam height and maximum storage capacity are 19.5 feet and 26.6 acre-feet, respectively. In order for a dam to be subject to the Dam Safety Law (NCGS 143-215.23) the impoundment must be both 25 feet in height or taller AND impound 50 acre-feet or more OR be located where failure will likely cause loss of life or serious damage to homes, industrial and commercial buildings, important public utilities, primary highways or major railroads. Since this structure is less than the required height and there is no apparent potential damage to downstream areas, the subject dam as proposed will remain classified as EXEMPT from the requirements of the Dam Safety Law. However, the following comments are offered. Our office encourages the owner of any dam to construct their dam using the same standards as would be applied if it were under the jurisdiction of the Dam Safety Law. 2. If the dam is constructed in such a way that it is 25 feet in height or greater as measured from the highest point on the crest of the dam to the lowest point on the downstream toe and will impound 50 acre-feet or more at the highest point on the crest of the dam, this dam will no longer be considered exempt. In this case, engineering certification, along with record drawings and specifications, will be required, as well as application processing fees. State of North Carolm I Environmental Quality I Energy, Mineral and Land Resources 1612 Mail Service Center I Raleigh, North Carolina 27699 919 707 9220 T Mr. Dale C. Stewart, PE Notice of Exemption June 26, 2018 Page 2 of 2 Cloer Dam UNION -062 3. If future downstream development occurs which would be impacted by a failure of the dam, then the hazard classification may be reassessed and may change from intermediate to high hazard classification. Please note that in accordance with NCGS §143- 215.25A(a)(6), dams which are determined to be high hazard are subject to the provisions of the Dam Safety Law of 1967 regardless of height or impoundment capacity. The Army Corps of Engineers and the Water Quality Section of this Department should be contacted to determine if additional permits are required. Also, the erosion and sediment control program having jurisdiction should be contacted to determine permit requirements. In any case, sediment must be prevented from entering the waters of the state or flowing onto neighboring property. Please contact Mr. Zahid Khan, CPM, CPESC, CPSWQ, Regional Supervisor, Land Quality Section, 610 E. Center Avenue, Suite 301, Mooresville, North Carolina 28115, telephone number (704) 663-1699, or a staff member of the Dam Safety Section at telephone number (919) 707- 9220 should you have any questions concerning this matter.
