As a community dependent upon the tourism industry, the atmosphere and aesthetic features of the community take on an economic value for the residents and Property Owners of Park City.  

It is in the best interests of the general welfare of the community to protect the aesthetic values of the community through the elimination of those architectural styles, and those Building and Landscape materials, which, by their nature, are foreign to this Area, and this climate, and therefore tend to detract from the appearance of the community.  

Most of Park City’s Main Street and many homes in Park City’s older neighborhoods are listed on the National Register of Historic Places as well as being locally designated as Historic Sites, which is a point of considerable importance to the tourism industry. New Development, while distinct from surrounding Historic Sites, should not detract from them. Park City is densely developed due to the shortage of level, buildable land.  

The effect of one Development is felt on the community as a whole.  It is the policy of the City to foster good design within the constraints imposed by climate, land ownership patterns, and a Compatible architectural theme.

It is also the intent of this section to encourage and implement water conservation practices for landscaping, as it is in the public's interest to conserve water resources and promote Water Wise Landscaping. Park City is in a mountainous, semi-desert environment where much of the precipitation occurs as snow during the winter months and the highest demand for water occurs during the summer months. The largest single water demand is for irrigation of landscaping. The use of Water Wise Landscaping will protect the health, safety, and welfare of the community from impacts of water shortages likely to occur during cycles of drought. Water Wise Landscaping is a concept of landscaping with plants that use little or no supplemental irrigation and are typically native to the region. The concept also requires water conserving irrigation practices, such as drip irrigation, Hydrozoning, and effective mulching with plant based mulches. Where applicable in Wildland-Urban Interface areas as demonstrated by the latest Utah State Department of Natural Resources Wildfire Risk Assessment Portal Map, Firewise Landscaping techniques shall be in accordance with Municipal Code Chapter 11-21.

All Uses within the Historic Districts and on Historic Sites outside the Historic Districts, both Allowed and Conditional, are subject to design review by the Planning Department for compliance with Chapter 15-11 Historic Preservation and Chapter 15-13 the Design Guidelines for Historic Districts and Historic Sites.  

Design review for all Uses, Allowed and Conditional, within the HRL, HR1, HR2, HRM, HRC, HCB Districts, and Historic Sites located outside these districts is initially performed by the Planning Department as set forth in Sections 15-11-12 Historic District and Historic Site Design Review, and Chapter 15-13 Design Guidelines For Historic Districts And Historic Sites.

Design review by the Historic Preservation Board is limited to matters outlined in Chapter 15-11, with all functional review of Conditional Uses performed by the City staff and/or Planning Commission per Section 15-1-10.

Conditional Uses outside the Historic Districts are subject to design review by the Planning Department. The standards of review are set forth in this Title, but additional design review standards may be adopted by resolution of the City Council, provided that resolution is consistent with the provisions of this Title.

Permitted Uses in all Zoning Districts outside the Historic Districts are subject to design review by the Planning Department. The standards of review are set forth in this Title.

1. PROHIBITED ARCHITECTURAL STYLES AND MOTIFS. The following architectural styles and motifs are prohibited in Park City because these styles and motifs have a strong connection or association with other regions:
   
   1. A-frame Structures;

   10. New Structures designed to imitate Historic Buildings and/or Structures built in Park City or elsewhere, unless the project complies with the Design Guidelines For Historic Districts And Historic Sites.
       
   11. EXEMPTION.
       1. The above provisions addressing Tudor, Victorian, and colonial styles and tower elements shall not apply in the Prospector Park Subdivision.
          
2. PROHIBITED SIDING MATERIALS. The following siding, fascia, and soffit materials are prohibited because they have proved to be unsuitable for Use in Park City due to the extreme climate, or because their appearance is such that the values of adjoining or abutting Properties are adversely affected:
   
   1. Thick shake shingles;
      
   2. Ceramic tiles;
      
   3. Slump bloc, weeping mortar;
      
   4. Plastic or vinyl siding;

       1. Vinyl siding, including soffits and fascia, and synthetic stone products may be permitted upon approval by the Planning Director, on Structures when such Structures are located in Areas predominately developed with Structures utilizing the same type of materials, such as in Prospector Village, Park Meadows and Prospector Park Subdivisions. The Applicant shall submit an exhibit documenting siding materials found in the surrounding neighborhood.
       2. Metal siding shall have a minimum thickness of .019 inches; shall be backed or insulated with a minimum of 3/8 inch fiberboard of polystyrene foam; and shall have a matte or flat finish.
       3. Plywood siding may be approved by the Planning Director if utilized as a base for board and batten siding;
       4. Existing Buildings with synthetic stone products and aluminum or vinyl siding may be re-sided or repaired using synthetic stone products and aluminum or vinyl siding with specific approval by the Planning Director.
          
3. DESIGN ORNAMENTATION.
   1. Architectural design in Park City has historically been simple. Highly ornate Buildings are inconsistent with the architectural patterns of the community, and due to the close proximity of one Development to another, inconsistent ornamentation may become unsightly and detract from Property values. 
      
      To add architectural interest to Buildings, special ornamental siding materials may be used, provided that no more than twenty five percent (25%) of any facade of the Building is covered with ornamental siding. Examples of ornamental siding provided for information purposes only and not as a limitation, are as follows:
      
      1. Fish scale cut shingles;
         
      2. Half-timbered stucco;
         
      3. Match-sticked wood or other inlays.
         
4. NUMBER OF EXTERIOR WALL MATERIALS.
   1. Different exterior siding materials add interest to a Building, and to the community as a whole, however, the Use of too many exterior materials, like excessive ornamentation, detracts from the values of adjoining Properties. Exterior walls of any Building may be sided with up to three (3) different materials per Building, but no more than three (3) materials may appear on any one (1) wall, including ornamental siding. Trim shall not be counted as a siding material, but ornamentation is counted as a siding material. If trim covers more than ten percent (10%) of a side of the Building, it shall be counted as a siding material on that side.
      
5. ROOFING MATERIALS.
   1. Because of the steep Grade changes within Park City, and the fact that residents and visitors are frequently in a position to look down on the City from the adjoining mountains, the appearance of roofs in Park City is of more significance than in other communities. Some roof types do not perform well in Park City’s harsh climate. In addition, the Area’s dry climate creates a high potential for wild land fires which makes the Use of wood roofs unsafe in some Areas. For these reasons, the following roof types are prohibited in Park City:
      
      1. Untreated aluminum or metal, except that copper may be used;
         
      2. Reflective materials;
         
      3. Roof colors shall be neutral and earth-tone, brightly colored roofing such as bright red, blue, yellow, green, white or similar colors are highly visible. Exception: Green is allowed if it is determined that its hue, color, chroma and other attributes of color are similar to other earth tone colors currently approved in Park City. In no case shall the color be determined to be bright or highly reflective or towards the yellow tones of the color spectrum;
         
      4. Wood shingles, including fire retardant, prohibited only in wild land interface zones. Wood roofs may be allowed on additions to existing Structures with wood roofs, only upon specific approval of the Chief Building Official. In addition, wood roofing may be allowed on later phases, which continue the specific design of existing projects and where the original phase has wood roofing; Existing non-conforming Structures must comply with this section when the Structure’s roof is replaced;
         
      5. Except on Historic renovations or reconstructions with adequate documentation, roof ornamentation such as scroll work, finials, and bead-and-dowel work are prohibited.
         
6. ROOF SHAPES.
   1. The following roof shapes are prohibited in Park City as the dominant roof form because they either do not perform well in the harsh climate, or tend to detract from the value of adjoining Property. As minor roof elements, the following shapes may be allowed if approved by the Planning Director:
      
      1. Mansard or fake mansard roofs;
         
      2. Gambrel roofs;
         
      3. Curvilinear roofs;
         
      4. Domed roofs;
         
      5. Geodesic domes;
         
      6. Conical roofs, greater than 270 degrees around;
         
      7. A-frame or modified A-frame roofs.
   2. Mechanical equipment on roofs must be hidden with a visual barrier so it is not readily visible from nearby Properties.
      
7. SOLAR ENERGY SYSTEMS. Any solar energy system shall be designed as follows:
   
   1. Solar Energy Systems shall be designed so as to be incorporated in the roof plan or architectural features of the structure to the best extent possible. Solar Energy Systems shall generally be mounted flush to the roof plane. In instances where due to the existing roof angle the panel needs to be angled from the roof plane for optimum solar gain, alternative designs may be considered upon review of a visual analysis and mitigation of visual impacts from surrounding properties.
      
   2. Solar panels, solar devices, and Solar Energy Systems and mounting equipment shall use non-reflective finishes such as an anodized finish.
      
   3. Solar energy systems in the Historic Districts are subject to the Design Guidelines for Historic Districts and Historic Sites and shall also meet the following:
      1. On a Flat Roof, the Solar Energy System shall be mounted flush to the roof or on racks. When this is not possible, the Solar Energy System shall extend no more than five Feet (5') above the highest point of the roof. Solar Energy Systems shall be screened from view of the primary right-of-way by:
         1. An existing parapet along the street-facing facade that is as tall as the tallest part of the Solar Energy System; or
            
         2. Setting the Solar Energy System back from the edge of the roof facing the primary right-of-way at least four feet (4') for each one foot (1') of Solar Energy System height (including any necessary racks).
            
      2. Solar Energy Systems are permitted on pitched roofs facing a rear or side lot line that is not visible from the right-of-way.  The Solar Energy System shall be mounted flush on the pitched roof, with the system no more than one foot (1’) from the surface of the roof at any point.  Solar Energy Systems shall be screened from view of the primary right-of-way in the following ways:
         1. The Solar Energy System shall be located at least one foot (1') from the ridgeline of the pitched roof.
            
         2. The Solar Energy System shall be located at least three feet (3') from the edge of the roof facing a right-of-way and one foot (1') from the edge of the roof facing the rear property line.
            
         3. The Solar Energy System shall not alter the slope of the roof.
            
      3. Solar shingles and Propanel-type/standing seam integrated products may be appropriate on roof surfaces visible from the primary right-of-way in the Historic Districts when it can be shown that they are sized similar to conventional asphalt shingles or metal roofing. They shall be similar in color to roofing materials in the Historic Districts and shall possess an anti-reflective top coating, such as Tempered Glass Tefzel Glazing or titanium dioxide. All metal surfaces shall have a matte finish.
         
      4. Freestanding Solar Energy Systems shall meet all the setback requirements of an Accessory Building as outlined in the Historic zoning districts. They shall be installed in locations that minimize visibility from the public right-of-way. These systems shall be screened from the public right-of-way with materials such as fencing or vegetation of suitable scale for the Historic District.
         
      5. Exceptions to the location and height of the Solar Energy System above the roof are subject to Planning Director approval based on a determination that:
         1. A professional experienced in energy-efficient construction has conducted an energy audit and the building has optimized its energy efficiency through other means; and
            
         2. The location of the Solar Energy System does not detract from the Historic character of the site and/or the Historic District (by making the Solar Energy System a character-defining element of the building); and
            
         3. The application has demonstrated that the proposed plan will result in a net positive generation of 105% or greater.
8. SKYLIGHTS. Any skylight, or other translucent roof material which allows the transmission of light from the interior of the Building to the exterior, shall be designed as follows:
   1. Skylights shall be limited to no more than twenty-five percent (25%) of the total roof Area;
      
   2. The skylight design shall facilitate the Use of natural light into the Building and any light emitted or reflected from the skylight shall be shielded from adjacent Properties;
      
   3. The skylight feature shall not be the highest point of the Structure; and
      
   4. The skylight feature shall be designed to fit as flush as possible with the roof. Skylights shall generally extend no more than two feet (2') above the roof plane.
      
   5. Skylights in the Historic Districts are subject to the Design Guidelines for Historic Districts and Historic Sites.
9. WINDOW TREATMENTS.
   1. Windows other than rectangular windows may be used as accents and trim, but arched, rounded, or Bay Windows as the primary window treatment are prohibited. Untreated aluminum and untreated metal window frames are prohibited. Small pane colonial style windows are not allowed. Untreated aluminum, untreated metal, vinyl, and other similar window frames are generally not considered appropriate in the Historic Districts (HRL, HR-1, HR-2, HRM, HRC, HCB), and on any site designated as Historic outside of the Historic Districts. The Planning Director may, however, consider requests for the Use of these materials. The design of the Structure shall be consistent with this Chapter. The Applicant will be required to bring a sample of the type and color of the material to be approved by the Planning Director.
      
10. OUTDOOR LIGHTING.
    
    1. PURPOSE. It is the intent of this Subsection to establish lighting practices and systems to minimize light pollution, glare, and light trespass; conserve energy and resources while maintaining nighttime safety, utility, and security; and curtail the degradation of the nighttime visual environment.
       
       It is recognized that the topography, atmospheric conditions, and resort nature of Park City are unique and valuable to the community. The enjoyment of a starry night is an experience the community desires to preserve. The City of Park City, through the provisions herein contained, promotes the reduction of light pollution that interferes with enjoyment of the night sky.
       
       The functional objectives in providing outdoor lighting are to illuminate Areas necessary for safe, comfortable, and energy-efficient Use. Outdoor lighting shall be limited to provide for safe entry and egress and for sign and Business identification.
       
       With the exception of Americans with Disabilities Act lighting requirements, the minimum lighting standards generally applied and recommended by the Illuminating Engineering Society of North America (IES) are observed by this Code.
       
    2. CONFORMANCE WITH APPLICABLE CODES. All outdoor electrically powered illuminating devices shall be permitted, inspected, and installed in conformance with the provisions of this Code, the International Building Code, the Electrical Code, the Illuminating Engineering Society of North America standards, and the Sign Code.

Roof mounted equipment and vents shall be painted to match the roof and/or adjacent wall color and shall be Screened or integrated into the design of the Structure. Minor exceptions to Setback requirements for Screened mechanical equipment may be approved by the Planning Director where the proposed location is the most logical location for the equipment and impacts from the equipment on neighboring properties, historic facades, and streetscapes can be mitigated and roof top mechanical placement and visual clutter is minimized.
13. PATIOS AND DRIVEWAYS. A Building Permit is required for all non-bearing concrete flatwork, asphalt, and/or any Impervious Surface, regardless of size or area. This includes any repairs, alterations, modifications, and expansion of existing flatwork. 
14. LANDSCAPING.
    1. PURPOSE. Park City is in a mountainous, semi-desert environment where much of the precipitation occurs as snow during the winter months and the highest demand for water occurs during the summer months, creating a significant risk of wildland fire. The largest single water demand is for irrigation of landscaping. Water Wise Landscaping incorporates non-invasive, drought-tolerant plants that require little or no supplemental irrigation once established, includes water conserving irrigation, and uses Hydrozoning in which plants with similar water needs are planted in the same area with mulches that prevent water evaporation. Water Wise Landscaping protects the health, safety, and welfare of the community from impacts of water shortages likely to occur during cycles of drought.
    2. WATER WISE LANDSCAPING. At least fifty percent (50%) of the Landscaped Area shall be Water Wise Landscaping containing approved non-invasive drought tolerant plants, and/or minimal irrigation. Water Wise Landscaping may be satisfied through approved vegetation, location of planting methods such as Xeriscaping or Hydrozoning, using healthy soil practices (that promotes soil moisture retention), such as compost, or biochar, and/or biodiverse plantings, or approved based on a site-specific Planning Department review.
    3. HOMEOWNER ASSOCIATION LANDSCAPING REGULATIONS. Homeowner Associations may not prohibit a property owner from installing Water Wise Landscaping.
    4. LANDSCAPE PLAN. A complete landscape plan is required for (I) new Development and/or Construction Activity proposed for an unimproved Lot or property and/or undisturbed natural Lots or property; (II) renovations or Construction Activity that modifies the Building Footprint; and (III) projects proposing to modify over 50% of the Landscaped Area. Landscape plans shall incorporate best practices for water conservation. The landscape plan shall:
       1. Identify the intended plant materials indicating the botanical name and the common name for:
          1. Plants (includes, but is not limited to trees and shrubs),
          2. Grasses,
          3. Mulches
          4. Rocks (greater than 3”) and Gravel (less than 3”)
             1. Gravel is only allowed in the following applications:
                1. as an approved walkway;
                2. patio;
                3. drainage plan; and/or
                4. defensible space
             2. Gravel is prohibited in areas adjacent to the Right-of-Way.
             3. Any Gravel, rocks, or stone within the HRL, HR-1, HR-2, HRM, HRC, or HCB Zoning Districts must meet the requirements of the Design Guidelines for Historic District and Historic Sites in Chapter 15-13.
             4. Gravel and rocks are not an allowed surface for parking, ground cover on berms, or finished grade with a ratio greater than 3:1, within platted or zoned open space. Rock-cover should be no more than 20% of the new ground cover. Wood chip mulch is encouraged for water retention on the landscape.
                Refer to the Planning Department for a City-approved Plant List. A diverse selection of plantings, and the use of clumping and clustering, is suggested to provide plantings appropriate to the Park City climate and growing season, to provide aesthetic variety, and to prevent the spread of wildfire.
       2. Utilize the concept of Water Wise Landscaping for selecting plants, plant location, irrigation methods, and mulching of all Landscaped Areas.
       3. For properties not included in a Historic District and for properties listed Landmark or Significant on Park City’s Historic Sites Inventory, include plantings and ground cover in the Wildland Urban Interface Immediate Ignition Zone 0-5 feet and the Wildland Urban Interface Intermediate Ignition Zone 5-30 feet (Park City Municipal Code § 11-21-1(I) The 2006 Utah Wildland-Urban Interface Code).
       4. Indicate the percentage of the lot that is landscaped.
       5. Indicate the percentage of the lot containing Impervious Surfaces, including driveways, parking areas, patios, and decks.
       6. Indicate the percentage of the landscaping that is irrigated.
       7. Identify the 50 percent (50%) of any Water Wise Landscaped Area comprised of appropriate approved non-invasive drought-tolerant plants.
       8. Identify Hydrozoning (grouping of plants based on irrigation needs) or Xeriscaping (sustainable, low-water landscaping) locations.
       9. Identify all existing Significant Vegetation, which shall remain and be maintained on Site and protected during construction.
          1. If the Significant Vegetation is determined to be unhealthy and/or unsafe, under a Site-Specific review conducted by the Forestry Board and Planning Director in conjunction with a Conditional Use, Master Planned Development, Historic District Design Review approval, or building permit review, it may be replaced with equivalent landscaping in type and size.
          2. The Forestry Board and Planning Director may grant exceptions if upon their review it is found that equivalent replacement is impossible, would be detrimental to the site’s existing and/or proposed vegetation, or violates Chapter 11-21 Utah Wildland-Urban Interface Code.
          3. Multiple trees from the City’s approved Wildland-Urban Interface Planting List, clumped and grouped together with canopies of the clusters being no closer than 18 feet to the next closest cluster within the Intermediate Zone, no cluster exceeding (5) five trees or cover more than 15% of the Intermediate Ignition Zone, whichever is lesser, and with vegetation not closer than 10 feet to any portion of a structure with vegetation at full grown height and size, equivalent in caliper to the size of the removed Significant Vegetation in the Intermediate Ignition Zone may be considered instead of replacement in kind and size.
          4. Significant Vegetation preservation shall be prioritized, but where applicable, Significant Vegetation may be removed or replaced to comply with Firewise Landscaping and/or Defensible Space regulations in Chapter 11-21 Utah Wildland-Urban Interface Code as approved by the Planning Director and Forestry Board.
       10. Identify Artificial turf, which is recommended to be non-toxic synthetic, plant based, and/or made of recycled materials with reduced petroleum-based polymers. Artificial turf is allowed to be used in limited quantities on decks, pathways, recreation and play areas. Installation of artificial turf shall not pool water and be installed to allow for drainage.
       11. Comply with Park City Municipal Code Chapter 11-21, Utah Wildland-Urban Interface Code.
           
           The Planning Director or designee may determine if proposed defensible space areas outlined in Chapter 11-21 Utah Wildland-Urban Interface Code may be exempt from 50% Water Wise landscaping requirements.
           
           All noxious weeds, as identified by the State of Utah or Summit County, shall be removed from the Property in a manner acceptable to the City and Summit County regardless of development state. All noxious weeds shall be removed prior to issuance of Certificates of Occupancy.
    5. IRRIGATION PLAN. A detailed irrigation plan shall be drawn at the same scale as the landscape plan and shall include:
       1. The layout of the heads, lines, valves, controller, backflow preventer, and drip irrigation;
       2. A WaterSense labeled irrigation controller which automatically adjusts the frequency and/or duration of irrigation events in response to changing weather conditions. All controllers shall be equipped with automatic rain delay or rain shut-off capabilities;
          1. Overhead Spray Irrigation shall be no greater than 12” above ground. Overhead irrigation is not permitted within 18” of any non-permeable surface. Overhead Spray Irrigation may be used for Lawn/Turf, but does not constitute a Water Wise landscaping method when used with other vegetation.
       3. Greywater System locations.
    6. 1. Lawn/Turf is prohibited on slopes with a ratio greater than 3:1.
       2. Irrigated Lawn/Turf areas are limited to a maximum percentage of the allowed Limits of Disturbance Area of a Lot or Property that is not covered by Buildings, Structures, Impervious Surfaces, or Active Recreation Areas based on the size of the Landscaped Area according to the following table:
          
          

          Landscaped Area	Maximum Turf or Lawn Area
          Greater than 250 square feet	20%
          Less than 250 square feet	No limitation

          
          
       3. Lawn/Turf is prohibited on parking strips or areas less than eight feet (8’) in width.
       4. Lawn/Turf area limitations apply to all city-owned property with the exception of an Active Recreation Area or as determined by the Planning Commission under a Conditional Use Permit review.

Encouraged Lawn/Turf practices include:

1. Only using Lawn/Turf in areas where it is functional, such as play areas, and areas needing temperature, noise, or dust mitigation;
2. Choosing non-irrigated Lawn/Turf or Lawn/Turf species with lower water requirements;
3. Not planting Lawn/Turf in narrow, small, or oddly shaped areas that are difficult to efficiently irrigate;
4. Mowing Lawn/Turf at a height of four inches (4”);
5. Planting Lawn/Turf in shaded areas on the lot;
6. Planting deep-rooted turfgrass on slopes;
7. Using healthy soil practices, such as biochar and/or compost;
8. Artificial turf is not recommended in any landscaping due to its impact on the Urban Heat Island Effect;
9. Per PCMC Title 13 Section 1-21(A): Areas using City water will be restricted to every other day from May 1 to September 30.

Hours of outside watering shall be restricted to between 7:00 p.m. and 10:00 a.m.
   

^*Pursuant to Utah Code Section 10-9a-534, no affirmative requirements may be imposed on “building design elements” for Single-Family or Duplex Dwellings, unless that Dwelling is:

1. located within an area designated as a historic district in:
   1. the National Register of Historic Places;
   2. the state register as defined in Utah Code Section 9-8-402; or
   3. a local Historic District or area, or a site designated as a Significant or Landmark Historic Site on the Park City Historic Sites Inventory, created by ordinance before January 1, 2021;
2. located within an area that:
   1. is zoned primarily for residential use; and
   2. was substantially developed before calendar year 1950; or
3. such requirement is imposed by a Development Agreement or other exception listed in Utah Code Section 10-9a-534.

Unless otherwise stated, prohibitions which do not impose a requirement shall apply.

Any design or any material that is not expressly prohibited by this Chapter, or a resolution adopted to supplement it, or by the Design Guidelines For Historic Districts And Historic Sites, are permitted.

In some cases, the Planning Director may vary from these standards if warranted by unusual or unique circumstances. In Single-Family Subdivisions, the Planning Department will consider the predominant architectural style and materials in the neighborhood to determine Compatibility. This may result in variation from the strict interpretation of this section and may be granted by the Planning Director.

1. Structures greater than sixty feet (60'), but less than 120 feet in length must exhibit a prominent shift in the facade of the Structure so that no greater than seventy five percent (75%) of the length of the Building Facade appears unbroken. Each shift shall be in the form of either a ten foot (10') change in Building Facade alignment or a ten foot (10') change in the Building Height, or a combined change in Building Facade and Building Height totaling ten feet (10'). 
   
2. Structures that exceed 120 feet in length on any facade shall provide a prominent shift in the mass of the Structure at each 120 foot interval, or less if the Developer desires, reflecting a change in function or scale. The shift shall be in the form of either a fifteen foot (15') change in Building Facade alignment or a fifteen foot (15') change in the Building Height. A combination of both the Building Height and Building Facade change is encouraged and to that end, if the combined change occurs at the same location in the Building plan, a fifteen foot (15') total change will be considered as full compliance.
   
3. The special facade and volume requirement of the Historic District are found in Chapters 15-2.1 through 15-2.6 and in the esign Guidelines For Historic Districts And Historic Sites, Chapter 15-13.
   
4. The facade length and variation requirements apply to all sides of a Building. 

Any project falling within the Sensitive Land Overlay Zone may be subject to additional architectural review requirements and regulations as outlined in Chapter 15-2.21.
