BOARD OF ADJUSTMENT 2021 CALENDAR ADOPTION Mr. Waddell motioned to approve the 2021 calendar. Mr. Kern second the motion. The 2021 calendar was unanimously approved and adopted by the board members. CASE ZBA-954 The Chairman then swore in Ken Vafier, Bradley Wivell and Matthew Nichols. Mr. Vafier stated the applicant, is requesting a variance from three ordinance provisions governing non- conforming situations and required front yard setbacks within the New Hanover County Unified Development Ordinance in order to construct a single-family dwelling within the B-2 District. Mr. Bradley Wivell, applicant and property owner, is requesting a variance from the discontinuance of a non- conforming use duration per Sections 11.4 and 11.6; and a variance of 20.4’ from the 35’ minimum required front yard setback in the B-2, Regional Business District per Section 3.4.5 D of the New Hanover County Unified Development Ordinance. The property is located at 1112 Elm Street. The parcel is located in the Seabreeze community in the southern section of New Hanover County. The parcel is one of several lots in the area that comprise approximately 10 acres which were zoned B-2 in 1971 due to their historic use as waterfront business and recreation destinations. Currently, the site is operating as a boat trailer storage lot which is affiliated with the applicant’s boat storage business located across Elm Street to the southwest of the subject site. The applicant was notified upon expansion to the lot a minor site plan would be required. After discussing plans for the site, staff was informed by the applicant that they wanted to construct a single family dwelling on the subject site. Mr. Vafier stated single family dwellings are not permitted in the B-2 district, but mentioned that there are some legal non-conforming uses in the area which pre-date the current zoning classification. Mr. Vafier stated there are criteria that allow legal non-conformities to remain until they are removed, however the continual use is not encouraged. Mr. Vafier stated that once the use is discontinued, the ordinance allows a 180-day duration after which the property may only be used for conforming uses. The applicant provided a survey of a home at the subject site in 2002, however, this home was not present when the applicant purchased the property in 2017. Staff has not located records to confirm a structure was on site within the 180-day time limit. Mr. Vafier stated once the use has been discontinued, the use can only be used for legal conforming uses such as a business or commercial use. As staff is not able to approve a single family home on the subject site; the applicant elected to pursue approval of a variance for constructing a home at the site. Chairman Moore asked how long has the 180-day duration rule been in the county in the ordinance. Mr. Vafier stated the variance request is for the single family structure. He stated the 180-day duration has been on the books prior to the adoption of the Unified Development Ordinance. 3 Mr. Waddell inquired if the property had a well and if the area will pass for perk test. Mr. Matthew Nichols, PLLC- Mr. Nichols presented representing Mr. Brad Wivell, who owns a local trailer and boat storage facility in the Seabreeze community. The storage business is located on the opposite side of the subject site. Mr. Nichols stated the community has a mixture of structures in the area in addition to the old home that was previously located on Mr. Wivell’ s parcel prior to 2017. Mr. Nichols stated that there is a mobile home across the street from the subject site that was removed and currently a single family dwelling is being constructed at this site. Mr. Nichols stated the subject site is 9/10 of an acre, which is extremely small due to the wide right of way of Elm Street. Mr. Nichols stated the subject site is challenging due to its size in the B-2 district. Mr. Nichols stated the applicant is requesting a single family dwelling to be built at the subject site. Mr. Nichols stated the situation was not created by the applicants, a rezoning of the site would not be beneficial to the applicant, the subject site is extremely small, and the applicant would be closer to his business across the street on Elm Street if the request were to be approved. Mr. Kern asked about the time from when the structure was removed to when the applicant purchased the parcel. Ms. Freeman inquired as to where the photos of the old house that were presented at the property came from. Mr. Nichols stated that Mr. Clyde Dinkins owned the property from approximately in 2003 -2012, and that photos of the old home were taken around 2012 per the date on the photos. Mr. Waddell asked if the applicant started using the property immediately after purchasing. Mr. Wivell stated he purchased the subject site in 2017 and starting utilizing it as a boat storage. He is requesting approval to construct a future home close to his business. Mr. Pate asked if tax records ever showed of a single family home on the subject site. Mr. Vafier stated the tax records shows no data for the subject site. PUBLIC HEARING CLOSED BOARD DELIBERATION Mr. Waddell asked if granting this variance would it set a precedent, and Ms. Freeman asked if the board would need to consider a prior case. Ms. Huffman stated the board is tasked with deciding if the request constitutes an acceptable application for variance proceedings. Ms. Huffman stated the board cannot grant a variance for a permitted use in a zoning district. Ms. Huffman stated that the applicant is requesting approval of a use that is not allowed at the subject site. Chairman Moore asked how long has B-2 zoning been in the Seabreeze community. 4 Mr. Vafier stated the B-2 zoning was applied to the area in 1971. Mr. Vafier stated this type of inquiry has been requested in past in the Seabreeze community. Mr. Vafier stated applicants have tried unsuccessfully to have certain areas in or near the community rezoned over the years. Mr. Kern asked in the past was the community a residential district. Mr. Vafier stated the area was both residential and non- residential. In addition, there was no zoning regulations in years’ prior when a lot of the community was constructed. Mr. Nichols displayed photos of mixed structures in the past of the community. Ms. Freeman asked if there are future plans for the Seabreeze area to become a more residential community, also if the UDO has language of rezoning small communities like Seabreeze and Castle Hayne. Mr. Vafier stated as residents purchase larger tracts and request of rezoning it’s possible these areas could be rezoned in the future, but there is not a current initiative to proactively rezone the area at the staff level. Chairman Moore re-opened the public hearing for applicant rebuttal. Mr. Nichols (rebuttal) Mr. Nichols referenced a case before the City of Wilmington’s Board of Adjustment at 6320 Oleander Drive which suffered a fire and the building at the time was subject to a time limit to reconstruct. This time limit had expired to rebuild and the applicant presented this hardship to the Wilmington Board of Adjustment. Mr. Nichols stated although the hearing was in the city’s jurisdiction, the request is similar to today’s case hearing whereby the board does have the authority to approve these type of request. Mr. Nichols stated the Wilmington Board of Adjustment request was approved and rebuilt. Mr. Nichols stated it is in the board’s authority to grant the variance as presented today. In addition, granting the variance would resolve a difficult situation for the applicant. No opposition to build the home has been received. Mr. Nichols concluded that the request is not a use variance. PUBLIC HEARING CLOSED Mr. Vafier stated that the owner across the street and Ms. Dinkins stated they had no opposition to the applicant’s request. Mr. Kern stated the applicant should not be punished due to not knowing when the home old home was removed. Ms. Freeman reiterated that a use variance is not allowed in the B-2 district. Chairman Moore stated that the 180-day use is a common time line within a county ordinance. Mr. Vafier stated that the applicant could apply for a special use permit or a live work-unit permit in order to construct a single-family dwelling, but would have to meet the respective UDO requirements for those uses. 5 Chairman Moore stated the board is tasked with upholding the ordinance. He recommended that the applicant work with staff on other avenues for a successful outcome. Ms. Freeman made a motion that the application is not eligible for board authority for approval. Chairman Moore second the motion that pursuant to state statute the application is not eligible for a variance, therefore a formal vote on the specific variance requests would not move forward. Chairman Moore, Vice-Chair Freeman and Mr. Waddell voted Nay. Mr. Kern and Mr. Pate voted yay. The vote was 3-2, and the request was not considered by the board as it was found to not be an eligible application for a variance. Chairman Moore motioned to adjourn. Mr. Kern second the motion. All ayes to adjourn the January 26, 2021 meeting. ________________________________ _________________________________ Executive Secretary Chairman Date: _____________ The minutes of this meeting are not verbatim* ZBA-955 Page 1 of 6 VARIANCE REQUEST BOARD OF ADJUSTMENT February 23, 2021 CASE: ZBA-955 PETITIONER: McAdams, applicant, on behalf of City of Wilmington, property owner. REQUEST: Variance from tree retention requirements per Section 5.3.4(C) and interior landscaping requirements per Section 5.4.5(C) of the New Hanover County Unified Development Ordinance (UDO). LOCATION: 205 Sutton Steam Plant Road PID: R04000-001-012-000 ZONING: I-2, Heavy Industrial District ACREAGE: 65.47 Acres BACKGROUND AND ORDINANCE CONSIDERATIONS: McAdams, applicant, on behalf of City of Wilmington, property owner, is requesting variances from two UDO provisions related to tree retention and interior landscaping requirements. The subject property consists of 65.47 acres located to the south of Sutton Steam Plant Road, north of Sampson Street, and is zoned I-2, Heavy Industrial. Currently, there are seven existing sports fields on the northern half of the property. The applicant intends to construct four additional sports fields for the southern portion of the property, totaling eleven sports fields. When applying the UDO language from these sections, the proposed development would require additional off-street parking, interior landscaping in the amount of eight percent of the parking area, and tree retention where 15 trees would have to be retained or planted for each acre of area on the parcel disturbed by the development. The subject tract was once a landfill and is now part of an EPA Brownfield Revitalization Program. This means that an environmental cleanup for the earlier use is active on the site. EPA Brownfield Revitalization Programs are common for abandoned industrial facilities, waste disposal sites, and former gas stations. These programs can aid in returning properties to productive future uses. Sites involved in Brownfield Revitalization Programs may have limitations accompanied with the redevelopment. These limitations on the subject parcel are because of a geocell cover system or soil cover system placed over the contaminated area. In the case of the subject site, vegetative restrictions within the landfill/brownfield boundary are placed on root depth and root runners. ZBA-955 Page 2 of 6 Figure 1: Aerial with Applicant’s Conceptual Plan with Staff Markups Under the provisions of the UDO, approximately 323 trees would be required to be planted within the proposed disturbed area (approximately 21.5 acres) as part of the tree retention requirements, and one tree per 144 square feet (approximately 49 trees) would be required to be planted to meet the interior parking standards. However, a large percentage of the site is occupied by landfill/brownfields, subject to restrictions on root depth, and available space outside the landfill/brownfields boundary is limited. According to the applicant, difficulties arise with providing the required number of plantings because of the vegetative cover restrictions on root depth within the landfill/brownfields. ZBA-955 Page 3 of 6 Figure 2: Variance Requested from Tree Retention Requirements per Section 5.3.4(C) and Interior Landscaping Requirements per Section 5.4.5(C) of UDO As such, the applicant is requesting the following variances: (A) A variance of 173 trees required from Section 5.3.4(C) of the UDO requiring that a minimum of 15 trees at least two inches DBH or two caliper inches, as applicable, shall be retained or planted on a parcel where development occurs. The applicant is proposing to disturb approximately 21.5 acres, requiring about 323 trees to be retained or planted. The applicant is proposing to plant about 150 trees outside of the Landfill/Brownfield boundary. (B) A variance of 49 trees required from Section 5.4.5(C) of the UDO requiring one planted or existing tree shall be required for every 144 square feet of total interior landscaped area, with a minimum of one tree in each parking island. The applicant is proposing for the interior parking landscaped areas to be increased from eight percent to about sixteen percent, providing more areas for shrubs because of the inability to plant trees. 5.3.4 TREE RETENTION STANDARDS TRANSITIONAL BUFFERS C. A minimum of 15 trees at least two inches DBH or two caliper inches, as applicable, shall be retained or planted on a parcel where development occurs in accordance with Section 5.4, Landscaping and Buffering. 5.4.5. PARKING LOTS C. Landscaping for parking lot interiors shall be in accordance with the requirements in Table 5.4.5.C: Standards for Parking Lot Interiors. ZBA-955 Page 4 of 6 Figure 3: Applicant’s Conceptual Plan with Staff Markups Illustrating the Landfill /Brownfield Boundary The applicant contends that the variance is necessary in order to be compliant with site vegetative cover standards for landfills/brownfields, as specified by North Carolina’s Department of Environmental Quality. When applying the UDO language from Sections 5.3.4(C) and 5.4.5(C), the landfill/brownfield boundary illustrated above in green is restricted by the Landfill Site Vegetative Cover documentation provided in your packet that states that root depth shall be no greater than 18 inches at maturity with no root runner greater than 6 inches. ZBA-955 Page 5 of 6 Figure 4: Applicant’s Conceptual Plan with Staff Markups Illustrating Areas Not Restricted For Vegetative Cover of Root Depth The applicant has submitted a landscaping plan that proposes about 150 understory trees to be placed outside the landfill/brownfields boundary located in red above. ZBA-955 Page 6 of 6 BOARD OF ADJUSTMENT POWER AND DUTY: The Board of Adjustment has the authority to authorize variances from the terms of the Unified Development Ordinance where, due to special conditions, a literal enforcement of the regulations would result in unnecessary hardship. In granting any variance, the Board may prescribe appropriate conditions and safeguards in conformity with the Unified Development Ordinance. A concurring vote of four-fifths (4/5) of the voting members of the Board shall be necessary to grant a variance. A variance shall not be granted by the Board unless and until the following findings are made: 1. Unnecessary hardship would result from the strict application of the ordinance. It shall not be necessary to demonstrate that, in the absence of the variance, no reasonable use can be made of the property. 2. The hardship results from conditions that are peculiar to the property, such as location, size, or topography. Hardships resulting from personal circumstances, as well as hardships resulting from conditions that are common to the neighborhood or the general public, may not be the basis for granting a variance. 3. The hardship did not result from actions taken by the applicant or the property owner. The act of purchasing property with knowledge that circumstances exist that may justify the granting of a variance shall not be regarded as a self-created hardship. 4. The requested variance is consistent with the spirit, purpose, and intent of the ordinance, such that public safety is secured, and substantial justice is achieved. ACTION NEEDED (Choose one): 1. Motion to approve the variance request based on the findings of fact (with or without conditions) 2. Motion to table the item in order to receive additional information or documentation (Specify). 3. Motion to deny the variance request based on specific negative findings in any of the 4 categories above. ORDER TO GRANT A VARIANCE – Case ZBA-955 The Board of Adjustment for New Hanover County, having held a public hearing on February 23, 2021 to consider application number ZBA-955, submitted by McAdams, applicant, on behalf of City of Wilmington, property owner, a request for a variance of 173 trees from Section 5.3.4(C) of the UDO requiring that a minimum of 15 trees at least two inches DBH or two caliper inches, as applicable, shall be retained or planted on a parcel where development occurs; and a variance of 49 trees required from Section 5.4.5(C) of the UDO requiring one planted or existing tree shall be required for every 144 square feet of total interior landscaped area, with a minimum of one tree in each parking island in a manner not permissible under the literal terms of the ordinance and having heard all the evidence and arguments presented at the hearing, makes the following FINDINGS OF FACT and draws the following CONCLUSIONS: 1.

Plants provide ecological diversity while preventing soil erosion. Additionally, landfills with established vegetated soil cover systems are considered aesthetically pleasing to the public. However, if plant roots puncture the liner, the soil cover system is then vulnerable to damage due to uprooting in extreme weather events. A list of plants that are suitable for these sites as alternatives to standard lawns has been developed. These plants will serve to retain soil placed over the waste and prevent erosion. 2.0 METHODOLOGY The purpose of this report was to create a plant list of species suitable for planting on pre- regulatory landfills with soil cover systems in the coastal plain and Piedmont of North Carolina (NC). These plant lists are an alternative vegetative cover to standard grasses and may be provided to property owners. Plants of interest are small shrubs and herbaceous plants, including grasses, grass alternatives, rushes, perennials, annuals, and groundcovers. 2.1 Plant Requirements The NCDEQ provided S&ME, Inc. and Carolina Silvics, Inc. with a list of specifications for plants. These requirements are intended to ensure that the cap lining is not damaged, plants used are suitable for the geographic province in which the landfill is located, and that plant growth and survival is not dependent on costly, routine maintenance. Plants included on the list must meet the following requirements: •Root depth no greater than 18 inches at maturity with no root runner greater than 6 inches, •Prevents soil erosion, •Not an exotic intrusive species, •Drought and pest resistant, •Can withstand extreme weather events, and •If woody, height not greater than 24 inches at maturity. Other characteristics that may be vital to sustain a healthy flora include but are not limited to: •Salt tolerance, •Freezing points, •Flood tolerance, and •Low maintenance requirements. Plants Suitable for Revegetation of Pre-Regulatory Landfill Sites with Soil Cover Systems May 2017 in the North Carolina Coastal Plain & Piedmont 2 2.2 Availability Search As plant lists not cognizant of current commercial availability often frustrate land management objectives, we began by contacting the North Carolina Nursery & Landscape Association for a list of large wholesale nurseries in the North Carolina coastal plain and Piedmont. Twelve (12) nurseries were contacted. Ten (10) were willing to share their current availabilities via email or online access. These 10 nurseries are listed in Table 1 below. Table 1. Nurseries contacted that were willing to share plant availability.

We then attempted to contact each provider to determine size of operation. The following six farms included in Table 2 were determined to be the largest in North Carolina and their availability was included in our lists. Table 2.

We then attempted to obtain the following information for each species/cultivar: • Scientific name, • Common name, • Invasive status, • Invasive potential/status, • Root Depth (in) at maturity, • Height (in) at maturity, • Drought tolerance (high, moderate, low), • United States Fish & Wildlife Service (USFWS) Wetland Indicator Status • Flood tolerance (high, moderate, low), • Salt tolerance (high, moderate, low), • Disease/insect resistance (high, moderate, low), • Animal resistance (high, moderate, low), • Annual/Perennial, • Maintenance requirements (high, moderate, low), • Recommended United States Department of Agriculture (USDA) hardiness zone, • Cold hardiness (high, moderate, low and/or minimum temp for survival (F)) • Suitability for NC Piedmont (USDA hardiness zones 8a, 7b & 7a), • Suitability for NC Coastal Plain (USDA hardiness zones 8b, 8a & 7b), and • other pertinent information readily available. Species determined to be invasive or to exceed maximum root depths or maximum height at maturity were removed from the lists. Those that remained were then researched for USFWS indicator status and drought tolerance. Species found to be drought intolerant or obligate wetland species (indicator status of OBL) were also removed from the lists. The lists were then revised to remove any species that additional research indicated would not be suitable. The main sources relied upon to gather this information were the USDA Plants Database and the Missouri Botanical Garden’s online site. Other online sources, such as personal blogs and antidotes, were used when these two sources lacked sufficient data. If information could not be found for a certain species/cultivar, that field was left blank. Plants Suitable for Revegetation of Pre-Regulatory Landfill Sites with Soil Cover Systems May 2017 in the North Carolina Coastal Plain & Piedmont 4 3.0 RESULTS Review of the availability lists from the nurseries yielded a total of 503 plant species/cultivars of shrubs, grasses/groundcovers, and perennials/annuals to be included on our initial list. Of these, 143 were determined to likely meet NCDEQ requirements and are included in Appendix A. Root depth information is scarce, and when available, typically is provided as minimum root depth versus maximum. As such, maximum root depth often had to be estimated based on other factors, and we cannot guarantee that all 143 species have root depths of less than 18 inches with no runners exceeding six inches. To ameliorate this concern, species that we are confident typically meet the 18-inch maximum rooting depth requirement were further separated and then ranked based on drought tolerance and maintenance. Species with moderate to high drought tolerance, low to moderate maintenance requirements, and strongly believed to have root systems less than 18 inches deep were included in our list of 53 preferred species. Each of the three preferred lists (species/cultivars of shrubs, grasses/groundcovers, and perennials/annuals) are discussed in more detail below. 3.1 Shrubs Shrubs provide habitat for birds and small animals and have varied bloom and fruit periods that can provide year-long aesthetic interest. Unfortunately, most shrubs grow greater than twenty- four inches tall and many require regular maintenance to maintain a pleasing shape. Two hundred and thirty-five (235) species of shrubs were obtained for our initial list. Nineteen (19) of these were determined to likely meet NCDEQ criteria; ten (10) made the preferred list and are shown in Table 3. Table 3. List of preferred shrubs for planting on pre-regulatory landfills with soil cover systems in North Carolina.

They are often low maintenance and some species provide habitat for birds and small animals. Unfortunately, most of the grass species have root depths greater than 18 inches. One hundred and five (105) species of grasses, rushes, and groundcovers were obtained from all of the nurseries contacted. Forty-four (44) were determined to likely meet NCDEQ criteria; eight (8) made the preferred list and are presented in Table 4. Table 4.

Most species have shallow root systems, are deer resistant, and require low maintenance. One hundred and sixty- three (163) different perennials and annuals were obtained from the nurseries contacted. Eighty (80) were determined to likely meet NCDEQ criteria; thirty-five (35) made the preferred list and are presented in Table 5. 4.0 CONCLUSION From a list of 513 potential plants currently commercially available at large wholesale nurseries in the coastal plain and Piedmont, 152 plants were determined to likely meet NCDEQ requirements for planting on pre-regulatory landfills with soil cover systems. Root depth is one of the most important requirements, but is also the statistic least readily available. The final list of 53 preferred plants that are expected to meet the height and root depth requirements, have moderate to high drought tolerance and low to moderate maintenance needs.

Plants exhibit the following characteristics: • Suitable for landfill containment / provides stabilization • Locally hardy to the Piedmont Region of North Carolina and/or native • Non-invasive / non exotic or intrusive • Root depth no greater than 18” • Drought and pest tolerant • Can withstand extreme weather events • No height greater than 24” at maturity for woody vegetation • No root runner to extend greater than 6” in depth SOIL PREPARATION The minimum soil depth for areas that will be seeded, planted with grasses, or groundcovers should be 18”. Adequate drainage is important. The soil specifications should include a drainage layer of gravelly sand, a substrate of loamy coarse sand followed by a layer of topsoil. Care should be taken to ensure soil is not compacted. Compacted soil will inhibit root growth and negatively impact the health of plant material. To avoid compaction, final grading should not be completed unless soil is dry. A 6” minimum drainage layer should be used. The minimum soil depth does not include this drainage layer. Plant material should be chosen based on the maintenance plans and budget for specific projects. Remediation projects typically require more maintenance to get plant material established.

P L A N T L I S T The following report outlines suitable vegetation options for landscaping closed landfills developed as parks. Plants included in the report are non-invasive, hardy substitutes for the standard lawn. Suitable plants for the site must thrive in a coastal plain ecosystem and meet the following requirements:  Root depth no greater than 18” at maturity  Prevents soil erosion  Not an exotic intrusive species  Drought and pest resistant  Can withstand extreme weather events  No height greater than 24” at maturity for any woody vegetation  No root runner that extends to a depth greater than 6” Stabilizing the landfill surface and prevent runoff are the important concerns when revegetating a landfill site. Typically, trees and shrubs’ root systems cause concern with damaging the surface of the containment system, therefore, vegetation with shallower root systems like grasses and perennials are better options. By utilizing native plants, a hardy, low maintenance, drought resistant landscape is established and simultaneously beautifies the landfill. The native plants over time develop into a self-sustaining ecosystem and eliminate the need for fertilizers, pesticides and irrigation. The following list of plants meet the criteria described above and are suitable for a coastal environment. All plants included in the list are North Carolina natives. 3 | T A S K O R D E R 6 7 9 M I S - P L A N T L I S T Proper soil preparation will influence the success of planting. Optimum soil depth for planting is 18-24”. Prior to planting, the soil should be prepared to have a healthy layer of topsoil. Soil should be tested for pH, nitrogen, phosphorus and other nutrients. Soil should be amended accordingly up to a 6” depth and within a few weeks of planting. Soil amendments should be performed no closer than one week from planting. It is important to avoid soil compaction, as it will hinder plant development. Upon planting, initial plantings of rapid growth annual or perennial grasses should be used to prevent soil erosion. The following plants exhibit the characteristics listed above but should be avoided due to their classification as exotic invasives:  Alternanthera philoxeroides (Alligatorweed)  Hedera helix (English Ivy)  Microstegium vimineum (Trin.) A. Camus (Japanese stilt-grass)  Arthraxon hispidus (Thunb.) Makino (Hairy jointgrass)  Miscanthus sinensis Andersson (Chinese silver grass)  Vinca minor L. (Common periwinkle)  Ajuga reptans L. (Bugleweed)  Chrysanthemum leucanthemum L.
