A. 
Zoning districts and intent statements.
Table 26-14
District Classification
Code Designation
Intent Statement
R-1 Single-Family Residential (not less than 20,000 square feet)
R-1
The district is composed of those areas of the City whose principal use is and ought to be single-family dwellings on the largest lot sizes. The regulations of this district are designed to create and preserve a predominantly suburban character. In addition to the dwellings permitted in this district, certain compatible recreational and public uses are conditionally allowed and strictly regulated to ensure harmony with the principal use of this district.
R-2 Single-Family Residential (not less than 15,000 square feet)
R-2
The district is composed of those areas of the City whose principal use is and ought to be single-family dwellings on the largest lot sizes. The regulations of this district are designed to create and preserve a predominantly suburban character. In addition to the dwellings permitted in this district, certain compatible recreational and public uses are conditionally allowed and strictly regulated to ensure harmony with the principal use of this district.
R-3 Single-Family Residential (not less than 10,000 square feet)
R-3
The district is composed of those areas of the City whose principal use is and ought to be single-family dwellings on moderately sized lots. The regulations of this district are designed to still create and preserve a suburban character but with slightly smaller lot sizes. In addition to the dwellings permitted in this district, certain compatible recreational and public uses are conditionally allowed and strictly regulated to ensure harmony with the principal use of this district.
R-4 Single-Family Residential (not less than 7,500 square feet)
R-4
The district is composed of those areas of the City whose principal use is and ought to be single-family dwellings on smaller lots. The regulations of this district are designed to create and preserve a predominantly urban character as evidenced by the smaller lot sizes. In addition to the dwellings permitted in this district, certain compatible recreational and public uses are conditionally allowed and strictly regulated to ensure harmony with the principal use of this district.
R-5 Single-Family Residential (not less than 6,000 square feet)
R-5
The district is composed of those areas of the City whose principal use is and ought to be single-family dwellings on small lots. The regulations of this district are designed to create and preserve a predominately urban character as evidenced by the small lot sizes. In addition to the dwellings permitted in this district, certain compatible recreational and public uses are conditionally allowed and strictly regulated to ensure harmony with the principal use of this district.
C-1 Local Business
C-1
The district is composed of those areas of the City whose principal use is and ought to be general retail, service, and repair business activities which serve the entire City and surrounding area. This district is provided to permit the development of these business activities, to protect adjacent areas against encroachment by incompatible uses, and to lessen congestion on public streets. To these ends, certain uses which would function more effectively in other districts and would interfere with the operation of these business activities and the purpose of this district have been excluded.
WROA Watson Road Overlay Area
WROA
The area consists of the properties fronting to Watson Road within the eastern and western boundaries of the City. It requires certain streetscape and design standards for all new development on existing parcels or combination of parcels and underlying permitted and conditional uses are those as shown in Table 26-15 (Permitted and Conditional Uses) for the C-1, PD-C, and PD-MXD Districts.
M-1 Light Industrial
M-1
The district is composed of the area of the City whose principal use is or ought to be light manufacturing, warehousing, and other limited industrial uses. These uses generate a minimum of noise, glare, odor, dust, vibration, air and water pollutants, fire, explosive, radioactive and other hazards, and harmful or obnoxious matter. This district is provided to permit the development of these industrial uses, to protect adjacent areas against encroachment by incompatible uses, and to lessen congestion on public streets. To these ends, certain uses which would function more effectively in other districts and would interfere with the operation of these industrial activities and the purpose of this district have been excluded.
Planned Development Districts
The purpose of the planned development districts is to provide a means of achieving greater flexibility in development of land in a manner not possible in conventional zones; to encourage a more imaginative and innovative design of projects; to promote a more desirable community environment; and to retain maximum control over both the structure and future operation of the development. The planned development regulations are not intended to allow excessive densities, or the development of incompatible land uses, either within the development, or as the development relates to the general neighborhood. Establishment of and regulations pertaining to planned development districts are contained in Article III (Applications and Procedures), § 26-10 (Planned development).

A. 
Permitted uses. In order to implement the intent of each zoning district and to regulate a variety of compatible uses within zoning districts, use categories and general uses have been established for principal uses of land and buildings. Table 26-15 indicates permitted uses (P) subject to general district and building type standards or any specific use standards, and conditional uses (C) subject to the discretionary review process in Article III, (Applications and Procedures) § 26-11 (Conditional use permit). Use categories, general uses and specific types of uses are established in Article IV, § 26-14 (Zoning districts established), and specifically described in Article II (Definitions), § 26-7 (Description of uses). This table enables general use categories. More specific types of uses within these categories may be subject to additional standards in §§ 26-16 (Standards applicable to all districts) and 26-17 (Standards applicable to specific uses and districts), or be subject to conditional review processes indicated in Article III (Applications and Procedures), § 26-11 (Conditional use permit).

However, in order to provide viewsheds into the portion of the development behind the fronting buildings, buildings located at the Watson Road frontage and adjacent to an entry road or drive shall be setback from such roadway or drive as depicted in Figure D-5 below.
026 Fig D-5 Viewshed.tif
Entry Road or Drive in Large Development
a. 
In locations where the side yard is adjacent to an existing or proposed street connecting to Watson Road generally on a north/south axis, the side yard or building setback line shall be not less than 50 feet measured from the center line of said street or not less than 32 feet from the back curbline of either side of said street;
b. 
In locations where the front yard is adjacent to an existing or proposed street connecting to Watson Road generally on a north/south axis, the front yard or building setback line shall be not less than 50 feet measured from the center line of said street or not less than 32 feet from the back curbline of either side of said street;
c. 
Either of these standards may be modified during the development plan or site plan review process of Subsection B3a or b of this section, but in any event the viewshed created by this standard shall not reduce the distance between buildings abutting either side of such road or entry drive to less than 100 feet;
d. 
Minimum rear yard. A minimum rear yard of 10 feet shall be provided. If any property adjacent to the site is zoned in an R-1 through R-5 or PD-R zoning classification, there shall be a fifty-foot rear yard and a solid masonry fence complying with the provisions of Article V (Site and Landscape Design Standards), § 26-22 (Fencing), of this chapter; and
e. 
Transitional yards, etc.
(1) 
Where a side or rear lot line coincides with a side or rear lot line of any lot in an adjacent residential zoning district (R-1 through R-5 or PD-R), then a landscaped yard of at least 12 feet in width complying with Article V (Site and Landscape Design Standards), § 26-21 (Landscape design standards), of this chapter shall be provided along such a lot. In addition, for any use that involves the construction of a new structure or the expansion of an existing structure, a solid masonry wall complying with the provisions of § 26-22 (Fencing) of this chapter of at least six feet but not more than eight feet in height shall be provided in such transitional yard within two feet of the property line.
(2) 
Where the rear or side wall of any non-residential structure is located directly across the street from the front yard of any residential structure located in a residential district, a landscaped yard of at least 12 feet in width complying with the provisions of Article V (Site and Landscape Design Standards), § 26-21 (Landscape design), and § 26-22 (Fencing), of this chapter shall be provided along the entire length of such rear or side wall.
(3) 
The transitional yard requirement may be modified by conditional use permit, development plan approval, or by site plan approval as provided in Article III (Applications and Procedures), § 26-10 (Planned development), § 26-11 (Conditional use permit), and/or § 26-12 (Major site plan and design review), of this chapter. Such modifications may impose more stringent or less stringent requirements in order to mitigate the adverse effects of one land use upon another or conflicts between two different land uses.
(4) 
Yard requirements as required herein or in other provisions of this chapter may also be impacted by other provisions of the Crestwood Municipal Code relating to fire and public safety requirements imposed during development plan, conditional use permit, or site plan review by City staff.
6. 
Off-street parking and loading. All off-street parking and loading is required to comply with Article VI (Access and Parking) of this chapter, but those requirements may be modified in conjunction with the site plan review process to reduce parking requirements and minimize paved surfaces based on the standards outlined in Subsection E3, of this section. Access to off-street parking and loading must be accessed via controlled access points and may not allow for parking that provides direct pull-in and back-out parking to and from Watson Road across the site frontage. To reduce curb cuts on to Watson Road, all off-street parking for new development or redevelopment of existing sites must have access to an adjoining street other than Watson Road and must provide for cross access to adjacent property.
7. 
Environmental controls. All development shall conform to the environmental performance standards provided in Article VIII (Supplemental Standards), § 26-38 (Environmental performance standards), and the stormwater management standards of Article V (Site and Landscape Design Standards), § 26-24 (Stream buffer protection), along with other applicable provisions of the Crestwood Municipal Code.

Signs. In conjunction with site plan review, the site plan must contain information to indicate the type, and location of all signage in compliance with the provisions of Article VII of this chapter must be provided and approved as part of site plan approval.
E. 
Development requirements, guidelines, and standards. To achieve the goals and objectives as outlined in Subsection A of this section and achieve the City's vision for the Watson Road Corridor, the following development standards are established for uses within the Watson Road Corridor subject to the provisions of Subsection B of this section. It is recognized that not all of the standards may be attainable with particular property or uses. Therefore, the regulations in the WROA are intended to provide flexibility to property owners and developers for many types of development particularly with respect to building height and development density. In addition, the regulations are meant to provide a certain degree of latitude to the Planning Commission and the Board of Aldermen to vary from these or other regulations when reviewing site plans in order to achieve the goals and objectives of the Comprehensive Plan and these regulations. The degree to which a site plan for development meets or exceeds the design standards set forth in this subsection shall be considered and will be evaluated when considering site plans for proposed development. A developer should be prepared to explain why certain development standards cannot be met or that alternatives serve the same purpose as the standard. The standards are intended to allow the Watson Road Corridor to become another recognized location within the City as a live/work/relax location. Examples of the various standards and/or design features intended to be carried out within the WROA are included throughout this section.
1. 
Building design. New buildings should be designed to include common features and materials so that a sense of place and character is created for the WROA.
a. 
Exterior building materials. Building materials should be used and installed in keeping with the chosen architectural style. Building material colors should be varied and complementary and three colors for all building elevations required. Except as minor accents for trim, such as window frames or entry doors, primary or garish colors should be avoided and subtle colors and earth tones are preferred. Materials should be of a scale appropriate to the pedestrian and complement adjacent structures. The table entitled "Exterior Material Legend" below provides a listing of acceptable/generally unacceptable materials. This table is intended to provide direction but is not intended to represent absolute approval or disapproval of any listed item and will depend on building architecture.
Exterior Material Legend
Acceptable Exterior Materials
Generally Unacceptable Exterior Materials
Brick or brick veneer
Vinyl or aluminum siding
Natural stone (limestone, brownstone, lannon stone, marble, granite)
Veneer-based plywood siding
Metal panels (used as accent features, includes types such as Alucobond, Alpolic, or similar)
Plywood panels (such as T1-11)
Cement-fiber siding
Plexiglas
Decorative concrete masonry units (CMU) or architectural cement block
Corrugated metal with exposed fasteners (used as accent features and comprising no more than 30% of the exterior building materials used)

Shake shingles
Brick and stone pavers
Manufactured stone
Commercial grade asphalt shingles
Slate roofing
Concrete tile roofing
b. 
Building details. Each building shall incorporate several common architectural features, appropriate for the architectural style chosen. Examples include pilasters, piers, columns, friezes, cornices, and window surrounds. Building elements, such as awnings, signs, doors, windows, and lighting, should complement the architecture of the building facade and finishes. (See Example 1.)
026 Ex 1 Bldg Details.tif
c. 
Design features and structures. Use of awnings, canopies, or other design features should enhance main facades, especially at building entries. Attached structures, such as covered arcades or porte cocheres, shall be compatible with and complement the overall design of the building and its facade. (See Example 2.)
026 Ex 2 Design Features.tif
d. 
Building entrances. Building entrances are required to be clearly delineated and indicate a clear transition from the exterior to the interior of the building. Every main entrance is required to have a special emphasis when compared to the other portions of the building. The building address should be clearly displayed in a readable typeface of sufficient size for reading from a vehicle at a reasonable distance and oriented to the street or drive frontage recognized by the US Postal Service and the City's Fire and Police Departments. (See Example 3.)
026 Ex 3 Bldg Entrances.tif
e. 
Facade articulation. Buildings and parking structures of three stories or less in height designed with completely flat facades and monotone color schemes are not permitted. All buildings and parking structures are required to have horizontal and vertical facade variations, such as pop-outs, bays, recesses, arches, banding, columns, or similar features. Buildings of more than three stories may have a flat facade of uniform design above the third floor. (See Example 4.)
026 Ex 4 Facade Articulation.tif
f. 
Height and roofline. Single-story buildings should have varying roofline elevations to add architectural interest and avoid the appearance of long, monotonous roofline expanses. A variation, such as a parapet or tower, is required every 50 feet of roofline. Also, if mechanical HVAC equipment that is installed on the roof of any structure in the WROA is visible from grade level in residential areas or is visible from Watson Road or any primary access road within a larger development, said equipment shall be screened by a wall with a finish surface compatible in design and color to that which is used as a finish building wall material. The back of parapets should also not be visible from Watson Road or any primary access road within a larger development and must match the color and materials of the building. (See Example 5.)
026 Ex 5 Height and Roofline.tif
g. 
Pedestrians/bicycle access. All buildings must be designed to encourage pedestrian activity and social interaction and create a walkable environment that encourages pedestrian access, as well as bicycle access, to and within the Watson Road Corridor and connectivity to the adjacent greenway trail system.
h. 
Windows. Windows are key to the overall design of a building and the relationship between the exterior and interior. Eye level windows are required to relate to the scale of a person. Clear glass for storefronts, windows and doors, within the retail merchandising areas is required. Slightly tinted glass for energy efficiency purposes may be used. Window tints shall be grey, blue, or bronze. Mirrored glass is prohibited. Window signage is strongly discouraged. (See Example 6.)
026 Ex 6 Windows.tif
i. 
Signs. Along exterior roadways ground signs or shopping center signs in conformance with Article VII (Sign Regulations) are permitted. Signs along interior roadways and driveways may only be located on buildings and will be planned for as part of the building's overall design and should integrate similar or complementary materials as the building, be harmonious in color, with controlled lighting and must include information to indicate the type, size, and location of all signage in compliance with Article VII of this chapter. (See Example 7.) Window and accessory signage as regulated in Article VII (Sign Regulations) is also permitted.
026 Ex 7 Corporate Logos.tif
(1) 
Corporate logos may be incorporated into a sign so long as the sign is compliant with the provisions Article VII (Sign Regulations) of this chapter and is an integrated element of the building design and facade.
(2) 
Signs, other than those indicating entry or exit locations, shall not be located on parking structures or within parking lots except for instances where parking structures contain ground floor retail uses.
(3) 
Billboards are not permitted on any property within the WROA District.
(4) 
Electronic message centers as defined in Article VII (Sign Regulations), § 26-33 (Design and location standards) are permitted in the WROA only upon the issuance of a conditional use permit by the Board of Aldermen pursuant to § 26-11 (Conditional use permit) of this chapter. In reviewing such applications for a conditional use permit, the Board of Aldermen shall determine whether the proposed electronic message center will meet all applicable criteria in Subsections A, B2, and F of § 26-11. Existing electronic message centers located within the WROA which were approved prior to the effective date of this Code section are allowed to continue to operate until such time as the sign becomes nonoperational, is removed, is repaired or refurbished, or is substantially modified. Once such electronic message center becomes nonoperational, is removed, is repaired or is substantially modified, a conditional use permit shall be obtained prior to returning such electronic message center to use. However, any existing sign may not be enlarged or otherwise altered to the extent that it is no longer compliant with the provisions of Article VII (Sign Regulations), § 26-33 (Standards and requirements by sign type), Subsection D8 (Electronic message centers or displays).
2. 
Site design. New developments are required to match or complement surrounding new developments and landscapes to create a building and site design which follows the standards of this chapter and adds positively to the overall WROA environment. Where applicable and appropriate site design should provide:
a. 
Outdoor seating at work places and restaurants that is:
(1) 
Situated to provide a pleasant environment for users that is not adjacent to parked automobiles or other environmental detriments;
(2) 
Located so as not to block or constrict entry and exit doors or impede pedestrian or bicycle movements; and
(3) 
Not located within the ten-foot shared sidewalk and bikeway on either side of Watson Road.
b. 
Access to adjacent sidewalks or bikeways with a paved, ADA-accessible pathway of not less than six feet in width from building entries and that is clearly delineated through parking areas or structures via changes in paving materials, texture, and/or color. Pedestrian easements and connections of appropriate width that can connect to other uses within the area shall also be provided where possible and appropriate with adjacent landscaping and lighting particularly where such connections are between buildings. (See Example 8.)
026 Ex 8 Adjacent Sidewalks.tif
c. 
To encourage and promote biking to and from the WROA, bike racks shall be provided at appropriate locations at any building.
d. 
Elements such as plazas or large patio areas that can be used for occasional entertainment events (subject to any required approvals in accord with the Crestwood Municipal Code) and promote social interaction in pleasant environments.
e. 
Signage for wayfinding both within a development and the area overall that is of clear and consistent design.
f. 
Public art of appropriate type and scale that can help to create an identity for the WROA.
g. 
Building placement. Building placement must comply with the following standards:
(1) 
The main facade of a building must be oriented to face the principal street on which it has frontage.
(2) 
Buildings on corner lots must be oriented so that the main facade is giving equal treatment to each street on which it has frontage. Also, these buildings should include a prominent architectural feature of greater height than the rest of the roof, or emphasis at the corner where the two public streets meet.
h. 
Utilities serving a site and the on-site structures must be located in underground easements that can serve multiple properties.
i. 
Screening. In addition to the following, screening shall be in compliance with Article IV (Zoning Districts and Use Standards), § 26-17 (Standards Applicable to Specific Uses and Districts), Subsection E (Required screening of mechanical equipment, trash, and loading areas for nonresidential uses):
(1) 
Loading and service areas shall be screened with walls and landscaping. Where adjacent to residential areas, loading and service areas shall be located away from bordering residential property lines whenever possible, and such areas must be completely screened and appropriately buffered with appropriate trees in accord with the standards set forth in Article V (Site and Landscape Design Standards), § 26-22 (Fencing). In all instances, views into loading and service areas from adjacent properties or uses must be minimized.
(2) 
Mechanical equipment, whether ground level or rooftop, shall be screened from ground-level view. Large trash receptacles, dumpsters, utility meters, satellite dishes, antennas, etc., shall be similarly treated and may not be located on the side of a building. Screening material shall consist of a masonry wall, sight-proof fencing of aluminum, steel, vinyl, dense landscaping, or any other such material that is found compatible and approved as part of the site plan approval process.
(3) 
Chain-link fencing (including cloth, canvas, or vinyl-slat covered), smooth-face concrete block, and barb or razor wire topped fences are permitted with Planning Commission approval.
j. 
Landscaping: The landscaping requirements shall be as established by Article V (Site and Landscape Design Standards),§ 26-21 (Landscape design standards), of this chapter. In addition, the following requirements shall apply to all landscape plans:
(1) 
A landscape plan sealed by a landscape architect registered in Missouri shall be submitted in conjunction with the development or site plan.
(2) 
A landscape plan shall be drawn to scale, include dimensions and distances, and clearly delineate all existing and proposed vehicular movement and parking, and the location, size, and description of all landscaping materials. All easements, transition buffer areas and setback areas shall be labeled and dimensioned. Outdoor furniture and fixtures for commercial and mixed-use development are encouraged and shall be considered part of the landscaping plan and identified on the landscape plan. The landscape plan must include an irrigation plan.
(3) 
The property owner or designated agent shall be responsible for the maintenance, repair, and replacement of all landscaping materials. All plant material and landscaped bed areas shall be tended and maintained in a healthy growing condition, free from refuse, debris and weeds.
k. 
Lighting. Proper layout, height, fixture selection, and lighting level shall be incorporated as part of the site design requirements. (See Examples 9 and 10.)
026 Ex 9 Decorative Lighting.tif
026 Ex 10 Lighting Plan.tif
(1) 
Site lighting shall use LED bulb technology of low-intensity from a concealed source, shall be of a clear white or amber light that does not distort colors, and shall not spill over onto adjoining properties, highways, or in any way interfere with the vision of oncoming motorists. Lighting fixtures shall be of a directional type capable of shielding the light source from direct view. The development plan or site plan must show the relationship of fixtures and the light patterns to each other, to the project site, to the unit development, and to the adjacent rights-of-way.
(2) 
Fixtures used to accent architectural features, landscaping or art shall be located, aimed, or shielded to minimize light spill into the surrounding environment. Light spill above the roofline shall be prohibited.
(3) 
Architectural lighting shall be recessed under roof overhangs or generated from a concealed source, low-level light fixture(s). Roof lights, lighted roof panels, and other methods of illuminating buildings are deemed inappropriate and are not allowed.
(4) 
Decorative, low-level intensity, nonconcealed source lighting that defines on-site vehicular and/or pedestrian ways are acceptable.
(5) 
The lighting plan shall not conflict with the landscape plan, and the two shall be submitted simultaneously for review.
3. 
Parking and access. Developments which, in the opinion of the Planning Commission and/or the Director of Public Services during site plan review, might generate a significant increase in traffic, vehicular turning movements, or alteration of traffic patterns, will require a traffic study by a traffic engineer to be reviewed by City staff. Site layout and design must address the needs of motorists, pedestrians, bicycles, and other forms of transportation. Access and safety on the site should be ensured for all users. In addition to the parking requirements established in Article VI (Access and Parking), § 26-25 (Intent and applicability) through § 26-30 (Alternative parking plans), the following will be required:
a. 
Major internal circulation roadways must be separated from parking areas using curb and gutter, landscaping, pedestrian walkways, and lighting.
b. 
Separated cross access for automobiles and pedestrians in parking lots is required. Cross access for pedestrians shall consist of a dissimilar material from the parking lot.
c. 
Pedestrian cross access within parking lots shall connect to sidewalks, bike paths, and/or multi-use paths within the public rights-of-way.
d. 
Loading and service areas should be located away from street edge and public circulation patterns.
e. 
Shared off-street parking for different categories of uses. In order to minimize stormwater runoff through minimizing paved surfaces, development in the WROA should encourage situations where shared parking might be appropriate. To encourage this concept and subject to site plan review by the Planning Commission and written authorization of the City Planner, business establishments may submit an alternate parking plan in conjunction with the provisions of Article VI (Access and Parking), § 26-30 (Alternative parking plans), of this chapter. The reduction in parking quantities allowed through shared parking shall be determined as a percentage of the minimum parking requirement as stated in Article VI (Access and Parking), § 26-27 (Design requirements), of this chapter and the requirements for alternative parking plans of § 26-30.
4. 
Clearance of existing improvements. Properties within the WROA that are cleared for future redevelopment and are not subject to an approved site plan in accord with the provisions of § 26-12B (Major site plan and design review) or § 26-10 (Planned development) above must have properly issued demolition and grading permits requiring all building and site improvements to be removed as part of the site clearance. In addition, the site must be properly graded and seeded with grass within 60 days of the completion of the grading or within a time period specified by the permit (permits) in consideration of the time of the year. Proper maintenance of the cleared site will be required in accord with the property maintenance provisions of the Municipal Code.
[1-12-2021 by Ord. No. 5119]
A. 
Purpose and intent. The general policy of the City is to allow uses, buildings, and lots that were created legally and in conformance with then-applicable requirements, but that do not conform to the current applicable requirements of these regulations to continue. However, it is also the policy of the City to bring such uses, buildings, and lots into conformance with current regulations as is reasonably practical. Nonconformities are not to be expanded, and they should be abolished or become conforming as quickly as the fair interest to the parties will permit. The intent of this section is to balance the interests of property owners in past investments, discourage investment that expands or reinforces nonconforming situations, and promote investment consistent with the Comprehensive Plan and these regulations.
B. 
Scope of provisions. The provisions of this section shall apply to all nonconforming uses, lands, and structures. A nonconforming land use or structure is one which existed lawfully whether by variance or otherwise, on the date this chapter or article or any amendment thereto became effective, and which fails to conform to one or more of the applicable regulations of this chapter or such amendment thereto. Such nonconformities may be incompatible with and detrimental to permitted land uses and structures in the zoning districts in which they are situated; they inhibit present and future development of nearby properties; and they confer upon their owners and users a position of unfair advantage.
C. 
Nonconforming uses of lots. Where, on the date of adoption or amendment of this chapter, a lawful use of a parcel or lot exists that is no longer permissible under the provisions of this chapter or amendment thereto, such principal use may be continued so long as it remains otherwise lawful subject to the following provisions:
1. 
Enlargement. No such nonconforming use of a parcel or lot shall be enlarged, expanded, or extended to occupy a greater area of land than was occupied on the date of adoption or amendment of this chapter and no additional accessory use, building, or structure shall be established thereon.
2. 
Relocation. No such nonconforming use of a parcel or lot shall be moved in whole or in part to any other portion of such parcel or lot not so occupied on the date of adoption of this chapter or amendment thereto or to a parcel or lot not in conformance with this chapter.
3. 
Discontinuance. If such nonconforming use of a parcel or lot ceases for any reason for a period of more than 180 consecutive days (except where government action causes such cessation) the subsequent use of such parcel or lot shall conform to the regulations and provisions set by this chapter for the district in which such parcel or lot is located.
D. 
Nonconforming buildings and structures. Where, on the date of adoption or amendment of this chapter, a lawful building or structure exists that could not be built under the regulations of this chapter or amendment thereto by reason of restrictions upon lot area, lot width, lot coverage, height, open spaces, off-street parking, loading spaces and setbacks, or other characteristics, such building or structure may be continued so long as it remains otherwise lawful subject to the following provisions:
1. 
Enlargement. Such building or structure may be enlarged, expanded, extended, or altered only if nonconformity is removed.
2. 
Damage. Should any such building or structure be damaged by any means to an extent of more than 50% of its replacement cost at the time of damage, it shall not be reconstructed except in conformity with the provisions of this chapter.
3. 
Relocation. Should any such building or structure be moved for any reason for any distance, it shall thereafter conform to the regulations of the district in which it is located after it is moved.
E. 
Repairs and maintenance.
1. 
Nothing in this chapter shall be deemed to prohibit the restoration of any structure and its use where such structure has been damaged by any means out of the control of the owner to an extent less than 50% of its replacement value (excluding the value of the land, the cost of preparation of land, and the value of any foundation adaptable to a conforming use) at the time of damage, provided that the restoration of such structure and its use in no way increases any former nonconformity, and provided further that restoration of such structure is begun within 180 days of such damage and diligently prosecuted to completion within two years following such damage.
2. 
Whenever such structure has been damaged to an extent of more than 50% of its replacement value (excluding the value of the land, the cost of preparation of land and the value of any foundation adaptable to a conforming use) at the time of damage, as determined by the Director of Public Services, or by any means within the control of the owner to any extent whatsoever, the structure shall not be restored except in full conformity with all regulations of the district in which such structure is situated.
3. 
When a structure is determined to be in violation of any applicable health or safety code by the Director of Public Services under any applicable ordinance of the City and the cost of placing the structure in condition to satisfy the standards under such ordinance shall exceed 50% of the reconstruction cost of the entire structure, such nonconforming structure shall not be restored for the purpose of continuing a nonconforming use.
4. 
None of the restrictions contained in this section shall limit the authority of the Board of Zoning Adjustment to grant relief for reconstruction of a nonconforming structure, as provided in Article I (General Provisions), § 26-3 (Administration and review bodies) Subsection D (Board of Adjustment).
F. 
Change of tenancy or ownership. Provided that there is no change in the nature or character, extent or intensity of such nonconforming use, building, or structure, other than signage, there may be a change of tenancy, ownership, or management of an existing nonconforming use, building, or structure.
G. 
Completion of pending construction and building permits. To avoid undue hardships, nothing in this chapter shall be deemed to require a change in plans, construction, or designated use of any building on which actual construction was lawfully begun prior to the effective date of adoption or amendment of this chapter and upon which actual building construction has been carried on diligently. Nothing herein contained shall require any change in the site plan or designated use of a building for which a building permit had been heretofore issued or plans or final subdivision plats which have been approved by the City at the time of the passage of this chapter or amendment, provided that actual construction is begun within 180 days of such permit issuance of approval thereto.
H. 
Conditional uses. Any use existing at the time of adoption or amendment to this chapter and which is permitted as a conditional use in a district under the terms of this chapter or amendment thereto shall be deemed a conforming use in such district and shall without further action be considered a conforming use.
I. 
Nonconforming lots of record. If through dedication of street right-of-way, the area of any lot or parcel already established via the provisions of the subdivision regulations is decreased below the minimum area required in the applicable zoning district, development rights shall not be denied.
J. 
Existence of nonconforming use.
1. 
A nonconformity shall not be deemed to have existed on the date this chapter or any amendment thereto became effective; unless:
a. 
It was in being on a continuous basis and to its fullest extent on such date.
b. 
If such nonconformity is a use, such use had not been abandoned.
2. 
In cases of doubt, and on specific questions raised, whether a nonconforming use exists shall be a question of fact and shall be decided by the Board of Aldermen after notice, a public hearing, and receipt of a report and recommendation of the Planning Commission.
K. 
Nonconformity as basis for variance. The existence of any present nonconformity anywhere in the City shall not itself be considered grounds for the issuance of a variance for other property.
L. 
Eventual removal or correction of nonconforming use. Within five years of the date of the adoption of this chapter or the date of adoption of any applicable amendments to this chapter, any use which is or becomes a nonconforming use shall be brought into conformance with the environmental performance standards established in Article VIII (Supplemental Standards), § 26-38 (Environmental performance standards). Any use listed in this subsection need not be discontinued in the event that the adoption of this chapter or amendments to this chapter changes the status of such use from that of a nonconforming use to that of a permitted use in the district in which it is located.
