Schedule C. Schedule C uses have widely varying parking demand characteristics making it impossible to specify a single off-street parking standard. A developer proposing to develop or expand a "Schedule C" use shall submit a parking study that provides justification for the number of off-street parking spaces proposed. The Zoning Officer shall review this study and any other traffic engineering and planning data that are relevant to the establishment of an appropriate off-street parking standard for the proposed use. A parking study shall include estimates of parking demand based on recommendations of the Institute of Traffic Engineers (ITE) and data collected for uses or combinations of uses that are the same or comparable to the proposed use. Comparability shall be determined by density, scale, bulk, area, type of activity and location. The study shall document the source of data used to develop the recommendations. After reviewing the parking study, the Zoning Officer shall establish a minimum off-street parking standard for the proposed use.

Computing Off-Street Parking And Loading Requirements.

Multiple uses. Lots containing more than one (1) use shall provide parking and loading in an amount equal to the total of the requirements for all uses.

Fractions. When measurements of the number of required spaces result in fractions, the required parking spaces shall be rounded up to the next whole number.

Area. Unless otherwise noted in the provisions, all square footage-based parking and loading standards shall be computed on the basis of gross floor area.

Employees, students and occupant-based standards. For the purpose of computing parking requirements based on the number of employees, students, residents or occupants, calculations shall be based on the largest number of persons working on any single shift, the maximum enrollment or the maximum fire-rated capacity that is applicable and that results in the greater number of spaces.

Unlisted uses. Upon receiving a development application for a use not specifically listed in an off-street parking schedule, the Zoning Officer shall apply the off-street parking standard specified for the listed use that is deemed most similar to the use proposed in the application or require a parking study in accordance with Schedule C.

Off-Street Parking For Persons With Disabilities. Off-street parking facilities shall be designed and constructed in accordance with all requirements of the American with Disabilities Act and the Uniform Federal Accessibility Standards.

Location Of Off-Street Parking Spaces.

[Ord. No. 1987, 11-2-2020]

On-Site. Except as otherwise specifically provide, required off-street parking spaces shall be located on the same lot as the principal use.

Residential Districts.

In "R-3" and less intensive districts, off-street parking of motor passenger vehicles shall not be permitted in grassy areas. Vehicles licensed as commercial vehicles and weighing less than six (6) tons may be parked within customary driveways.

The paved area of driveways serving single-family or duplex uses shall not exceed thirty-five (35) feet in width within the exterior setback in which the driveway is located. Driveways serving single-family or duplex uses shall provide a minimum of exterior space to park two (2) vehicles side-by-side.

On-street parking of vehicles with a gross vehicle weight greater than three-quarter (3/4) ton or containing more than two (2) axles shall be prohibited in "R-3" and less intensive districts. This provision shall not prohibit temporary parking of vehicles making pickups or deliveries.

In no event shall vehicles be parked on the grass or in any open space or yard area. For the purposes of this Section, a vehicle is every device in, upon, or by which any person or property is or may be transported or drawn upon a roadway, waterway, or via air whether in operational or non-operational condition.

All off-street parking areas and all access drives shall be improved in a manner as described in Subsection (K). This applies equally to all property in all zoning districts, except in the "A" and "R-1" districts it shall apply from the street to a minimum distance of seventy-five (75) feet and thereafter a rolled stone/compacted aggregate measuring at least six (6) inches in depth shall be a minimum requirement. The aggregate paving material gradations and thickness must be sufficient to provide a stable all-weather surface for the vehicles that routinely use the drive. The drive must also maintain dust control methods to reduce air pollutants.

Non-Residential Districts. In "C-1" and more intensive districts, no off-street parking spaces shall be permitted within fifteen (15) feet of public street right-of-way. Motor passenger vehicles shall not be permitted in grassy areas.

Parking In Excess Of Minimum Standards. Off-street parking spaces provided in excess of minimum standards shall comply with all standards of this Section.

Use Of Off-Street Parking Spaces. Required off-street parking areas shall be used solely for the parking of licensed motor vehicles in operating condition and shall not be used for the storage of vehicles, boats, motor homes, campers, mobile homes or materials.

Off-Site Parking. Required off-street parking spaces shall be located on the same lot as the use it is intended to serve, provided that the Zoning Officer shall be authorized to allow all or a portion of required off-street parking spaces to be located on a remote and separate lot from the lot that the principal use is located if the off-site parking complies with the following standards.

Ineligible activities. Off-site parking shall not be used to satisfy the off-street parking standards for residential uses, restaurants, bars or convenience stores and to the convenience-oriented uses. Required parking spaces reserved for persons with disabilities shall not be located in an off-site parking facility.

Location. No off-site parking space shall be located more than three hundred (300) feet from the primary entrance of the use served, measured along the shortest legal, practical walking route. Off-site parking spaces shall not be separated from the use by a street right-of-way with a width of more than eighty (80) feet unless a grade-separated pedestrian walkway is provided.

Zoning classification. Off-site parking areas shall require the same or a more intensive zoning classification than that required for the use served.

Agreement for off-site parking. In the event that an off-site parking area is not under the same ownership as the principal use served, a written agreement shall be required. An attested copy of the agreement between the owners of record shall be submitted to the Zoning Officer for recordation on forms made available in the office of the Planning and Zoning Department. Such agreement shall take place before issuance of a building permit for any use to be served by the off-site parking area.

Off-Street Parking And Loading Area Design Standards.

Surfacing. All off-street parking and loading areas, except those required for single-family or duplex uses, shall be surfaced with:

Five (5) inches of concrete;

Six (6) inches of asphalt;

Three (3) inches of asphalt combined with eight (8) inches of aggregate base and subgrade base.

Off-street parking areas serving single-family and duplex residences shall be graded and paved with an approved asphalt, concrete or paver brick over an approved base.

Lighting. Any off-street parking areas, providing space for five (5) or more vehicles, that are used after dark shall be provided with lights that provide at least an average of one-quarter (¼) foot-candle over the entire parking area, measured on the ground surface within the parking area. Off-street parking areas in "M-1" and "M-2" Districts shall be exempt from the minimum lighting standards of this Subsection. Parking lot lighting shall be subject to the outdoor lighting standards of Section 405.250.

Drainage. All off-street parking and loading areas shall be designed to not increase the rate of stormwater runoff onto adjoining properties or streets. Drainage plans for off-street parking and loading areas shall be reviewed by the City Engineer.

Curbing. The perimeter of all off-street parking and loading areas and their access drives shall be curbed, with the exception of driveways for single-family and duplex residences. Landscaped islands and other interior parking features shall also be protected by curbs.

Striping. Off-street parking areas contained five (5) or more spaces shall be delineated by pavement striping.

Parking space dimensions. Required off-street parking spaces shall be designed in accordance with the minimum standards shown in Table 600-1.

Before approving any parking layout, the Zoning Officer shall determine that the spaces provided are usable and meet all applicable standards of this Unified Development Code. All required off-street parking spaces shall be clearly marked on the plan.

Section 405.216 Parking Lot Maintenance.

[Ord. No. 1515 §8, 6-5-2006]

All parking lots shall be maintained free of dust, paper and other loose particles. All adjacent sidewalks shall be kept free from dirt, in a safe condition for use by pedestrians. All signs, markers or any other method used to indicate the direction of traffic movement and the location of parking spaces shall be maintained in a neat and legible condition. Any walls, trees, shrubbery and the surfacing of the lot shall be maintained in good condition for parking purposes and the City Engineer or his/her designee shall have the authority to prohibit the use of the area for parking purposes until proper maintenance, repair or rehabilitation is complete.

Section 405.220 Driveways and Roadway Access.

[Ord. No. 1383 §601, 1-6-2003]

The following standards shall apply to all driveways providing access to multi-family or non-residential uses:

General Standards.

Off-street parking spaces shall be arranged so that no vehicle will back directly onto a street. All private parking areas and circulation drives shall be located off of the street right-of-way.

Access to property shall be allowed only by way of driveways and no other portion of the lot frontage shall be used for ingress or egress.

Any driveway design must allow an entering vehicle turning speed of fifteen (15) miles per hour to help reduce interference with through street traffic. Radii of driveway shall be sufficient to achieve this standard for the types of vehicles that the driveway is intended to serve.

There must be sufficient on-site vehicle storage to accommodate queued vehicles waiting to park or exit without interfering with street traffic.

Provisions for circulations between adjacent parcels should be provided through coordinated or joint parking systems.

Driveway placement should be such that loading and unloading activities will in no way hinder vehicle ingress or egress.

Driveway design must be such that vehicles entering the driveway from the street will not encroach upon the exit lane of a two-way driveway. Also, a right-turning exiting vehicle will be able to use only the first (1st) through-traffic land available without encroaching into the adjacent through-lane.

Right-Turn Lanes And Tapers. Right-turn lanes and taper shall be required when:

Expected right-turn ingress movements meet or exceed fifty (50) vehicles per hour during a typical weekday peak traffic period.

Driveway volumes are expected to meet or exceed one thousand (1,000) vehicles per day calculated using the Institute of Transportation Engineers site generated traffic standards for closest matching land use category as set forth in the most recent edition of the ITE Trip Generation Manual.

The City Engineer can document through traffic analysis that such treatment is necessary to avoid congestion and/or unsafe conditions on the public arterial.

Driveway Grade. The grade of a two-way, one-way or divided driveway shall not exceed two percent (2%) for a minimum distance of twenty-five (25) feet from the edge of the pavement.

Sight Distance. Direct-access driveways shall be located to allow the following minimum sight distance:

	Design Speed of Street (MPH)	Minimum Sight Distance (Feet)
	30	200
	35	225
	40	275
	45	325
	50	350

Driveway Spacing.

Arterial streets. Direct access to an arterial street shall be permitted only when the subject property has no other reasonable access to the street system and only if the Planning and Zoning Commission with the recommendation of the City Engineer determines that the proposed access point onto the arterial street can be accommodated safely. When direct access to an arterial street is approved by the Planning and Zoning Commission with the recommendation of the City Engineer pursuant to the requirements of this Section, the following standards shall apply.

Spacing from signalized intersections. All driveways providing access to arterial streets shall be constructed so that the point of tangency of the curb return radius closest to a signalized or stop sign-controlled intersection is at least two hundred fifty (250) feet from the perpendicular curb face of the intersecting street. In the event that this standard cannot be met because of an unusually narrow or shallow lot size, the Planning and Zoning Commission with the recommendation of the City Engineer may reduce the spacing so long as the reduction does not result in an unsafe traffic condition.

Spacing from other (non-signalized) access points. All driveways providing access to arterial streets shall be constructed so that the point of tangency of the curb return radius closest to all non-signalized street or driveway intersections is at least two hundred (200) feet from the perpendicular curb face of the intersecting street or driveway. In the event that this standard cannot be met because of an unusually narrow or shallow lot size, the Planning and Zoning Commission with the recommendation of the City Engineer may reduce the spacing so as the reduction does not result in an unsafe traffic condition.

Waivers. Waivers for these access standards may be approved by the Planning and Zoning Commission with the recommendation of the City Engineer if the City Engineer determines that the requested waiver will not create a serious detriment to the safety or operation of traffic on the street or roadway. The Planning and Zoning Commission with the recommendation of the City Engineer may require that the applicant for a waiver submit a traffic analysis if it is determined that such an analysis is necessary in order to render a competent decision on the requested waiver.

Driveways Per Parcel.

Unless otherwise specifically restricted, one (1) driveway opening shall be allowed per two hundred (200) feet of continuous street frontage. At least one (1) driveway shall be permitted for any lot.

Parcels with two hundred (200) feet of frontage or less may apply for a secondary driveway if shared with an adjoining parcel, provided that the required minimum spacing is maintained. In such cases, only one (1) shared driveway will be permitted.

Driveway Width. Except for dual driveways approved by the Planning and Zoning Commission with the recommendation of the City Engineer, the width of the driveway throat shall not exceed thirty-five (35) feet in width.

Right-of-Way Work Permit. No construction, grading, excavation, repair or reconstruction of any street, curb or gutter or any sidewalk or driveway between the street and property line shall be commenced without first obtaining a right-of-way work permit from the Zoning Officer.

Section 405.225 Zoning District Property Development Standards — Measurements and Computations.

[Ord. No. 1383 §602, 1-6-2003; Ord. No. 1515 §9, 6-5-2006]

The zoning district standards of Article IV establish many property development standards that apply within individual zoning districts. The rules governing exemptions, computations and measurements related to zoning district property development standards are established in this Section.

Lot Size.

Reduction of public purpose. When an existing lot is reduced because of conveyance to a Federal, State or local government for a public purpose and the remaining area is at least seventy-five percent (75%) of the required minimum lot size for the district that it is located, then that remaining lot shall be deemed to comply with the minimum lot size standards of this Unified Development Code.

Utilities. Utilities (major or minor) using land or an unoccupied building requiring less than one thousand (1,000) square feet of site area are exempt from the minimum lot size standards of all zoning districts.

Single-family dwelling and two-family dwelling exemptions. The minimum lot size standards of this Unified Development Code shall not be interpreted as prohibiting the construction of a single-family or two-family dwelling unit, in accordance with all other applicable regulations, on a lot that was legally platted or recorded before the adoption of this Unified Development Code.

[Ord. No. 1933, 2-19-2019]

Residential Densities. The zoning district regulations of this Unified Development Code express maximum residential densities in terms of lot area requirements per dwelling unit. The maximum number of dwelling units allowed on a lot shall be determined by dividing the subject lot's total lot area by the applicable lot area (per dwelling unit) requirement of the district. The number of dwelling units permitted in a mixed-use building (one containing residential and non-residential uses) shall not be affected by virtue of the building's mixed-use status. As with non-mixed-use projects, the maximum number of dwelling units allowed shall be calculated by dividing the subject lot's total lot area by the applicable lot area requirement of the district.

Setbacks.

Features allowed within setbacks. The following features may be located within setbacks:

Trees, shrubbery or other landscape features;

Fences and walls, subject to Section 405.245;

Driveways and sidewalks;

Signs, where permitted;

Steps to the principal entrance, walks and balustrades;

Bay windows, architectural features, cantilevered floors, chimneys and other ornamental features of buildings that do not project more than two (2) feet into the required setbacks;

Fire escapes that do not extend into a setback by more than thirty percent (30%) of the required setback dimension; and

Utility lines, wires and associated structures, such as power poles.

Side or rear setback exemptions in "M-1" and "M-2" Districts. No side or rear setback shall be required in the "M-1" and "M-2" Districts on any lot that adjoins a railway right-of-way or that has a rear railway track connection, provided that sufficient access for fire-fighting equipment is available. Such access shall be approved by the Fire Chief before issuance of any permit.

Setback averaging. If the existing front setbacks of lots within the same block with the same zoning classification and fronting on the same side of the street are less than the required front setback of the underlying zoning district, applicants shall be allowed to use the "average" front setback of the underlying zoning district, applicant shall be allowed to use the "average" front setback on that block. In such cases, the "average setback" shall be the mean (average) setback of all lots on the same side of the street within the same side of the street within the same block as the subject property. In no event shall lots with different zoning classifications or undeveloped lots be included in the calculation. This provision shall not be interpreted as requiring a greater front setback than imposed by the underlying zoning district and it shall not be interpreted as allowing setbacks to be reduced to a level that results in right-of way widths dropping below established minimums.

Setback reduced for public purpose. When an existing setback is reduced because of conveyance to a Federal, State or local government for a public purpose and the remaining setback is at least seventy-five percent (75%) of the required minimum setback for the district that it is located, then that remaining setback shall be deemed to satisfy the minimum setback standards of this Unified Development Code.

Height.

Fences or walls. In the case of fences or walls, height shall be measured on the side with the least vertical exposure above finished grade to the top of the fence or wall.

Exemptions from height standards. The following structures and features shall be exempt from the height requirements of this Development Code:

Chimneys, smokestacks or flues;

Cooling towers and ventilators;

Elevators bulkheads and stairway enclosures;

Grain elevators and silos;

Flagpoles, radio and television receiving antennas and support structures, provided that they shall not exceed one hundred fifty percent (150%) of the maximum height permitted within the zoning district that they are located, measured from average finished grade at the base of the support structure or building that it is located;

Communication towers;

Utility poles, water towers and support structures;

Belfries, spires and steeples; and

Monuments and ornamental towers.

Section 405.230 Landscaping and Buffering.

[Ord. No. 1383 §603, 1-6-2003; Ord. No. 1420 §6, 11-17-2003]

This Section sets out the minimum landscaping and buffering requirements for new development within the City of Oak Grove. Three (3) different types of landscaping and buffering are described in this Section: (1) open space landscaping; (2) parking lot landscaping; and (3) right-of-way and transition buffers.

Applicability. The standards of this Section shall apply to all development except that specifically exempted in Section 405.230(B). If an applicant is unable to meet the requirements of Section 405.230 due to physical or other constraints on the property, the applicant may submit an alternate Landscaping Plan. The alternate Landscaping Plan shall be reviewed and may be approved by the Planning and Zoning Commission and the Board of Aldermen if it is determined, in their sole discretion, that the proposed adjustments from the landscaping requirements in Section 405.230 as shown on the alternate Landscaping Plan will result in an equal or higher quality development overall.

Exemptions. The following shall be exempt from the standards of this Section:

Agriculture. Agriculture (limited) in the "A" District.

Open Space Landscaping. The open space landscaping standards shall apply to all development.

Plants required. At least one (1) medium or large deciduous tree and four (4) shrubs shall be provided for each one thousand five hundred (1,500) square feet of lot area or fraction thereof. Open space is defined as any space not covered by buildings, parking or athletic fields.

Location of plants. Plants required pursuant to this Section shall be installed in required front setback areas to the maximum extent possible.

Limit on plants required for residential development. In no case shall more than three (3) medium or large deciduous trees and four (4) shrubs be required to be installed on any single-family lot.

Parking Lot Landscaping. These parking lot landscaping standards shall apply to the interior of all off-street parking areas containing more than ten (10) off-street parking spaces. They shall not apply to vehicle/equipment storage lots, vehicle and equipment sales lots or multi-level parking structures.

Relationship to other landscaping standards. Landscaping provided to meet the open space or right-of-way and transition buffer landscaping standards of this Section shall not be counted towards meeting a project's parking lot landscaping requirements.

Minimum planting area. At least twenty (20) square feet of landscape planting area shall be provided within the interior of an off-street parking area for each parking space contained within the parking area.

Plants required. At least one (1) medium or large deciduous tree and six (6) shrubs shall be provided for each ten (10) parking spaces within an off-street parking area. All landscaping areas that are not dedicated to trees or shrubs shall be landscaped with grass, ground cover or other appropriate landscape treatment. Sand or pavement shall not be considered appropriate landscape treatment.

Location. Parking lot landscaping shall be reasonably dispersed throughout off-street parking areas.

Planting areas. The interior dimensions of any planting area used to satisfy parking lot landscaping standards shall be sufficient to protect plant materials and to ensure proper growth. Planting areas that contain trees shall be at least seven (7) feet wide and all planting areas shall be protected by raised curbs or wheel stops to prevent damage by vehicles and vehicle overhang.

Right-of-Way And Transition Buffers. The right-of-way and transition buffer standards of this Section require landscape buffers to be provided and maintained when certain land uses are adjacent to one another or when adjacent to certain roadway types. The standards are intended to help ease the land use transition between areas of varying development intensity, ensure land use compatibility, and preserve the appearance of roadway areas.

Exemption for "C-2" District. Uses in the "C-2" District shall be exempt from the right-of-way buffer standards.

Determination of right-of-way and transition buffer requirements. The following procedure shall be followed in determining the type of buffer required.*

Identify the minimum zoning classification required to accommodate the proposed use. This is the "Proposed Development/Zoning" classification of Column 1.

Identify the actual zoning classification of the abutting site(s). This is the "Adjacent Development/Zoning" classification.

Identify the classification of the roadway adjacent to the site of the proposed development. This is the "Adjacent Street" classification.

Determine the type of buffer required on each building site boundary (or portion thereof) by referring to the Right-of Way and Transition Buffer Table.

Refer to Section 405.230(E)(3) (Description of Buffer Types and Options) and select the desired landscaping buffer option from those set forth in that Section. Any of the listed options, at the option of applicant, may be used to satisfy right-of-way and transition buffer requirements.

* See the Right-of-Way and Transition Table included as an attachment to this chapter.

Description of buffer types and options.

		Required Plants Per 100 Linear Feet of Buffer
Buffer	Width (feet)	Shade Trees	Understory Deciduous	Understory Evergreen	Shrubs
A	15	2		2	4
B	20	2	2	2	6
C	25	3	2	4	8
D	40	3	4	6	10

Location of buffers. Right-of-way and transition buffers shall be required to be located along those portions of a site that are adjacent to public right-of-way and along those portions adjoining lots with a different zoning classification.

Use of buffers. Required buffers shall be reserved solely for open space and landscaping. No proposed building addition, structure, parking area or any other type of physical land improvement shall be located in a required buffer, provided that driveways or roads may cross a required buffer if necessary to provide access to the building site. Sidewalks and pedestrian paths may also be located within required buffers.

Waiver for small sites. The area of required right-of-way and transition buffers shall not be required to exceed ten percent (10%) of the site proposed for development. In cases where buffer requirements would consume more than ten percent (10%) of the site, the Planning Commission may allow the width or location of buffers to be reduced or eliminated. The developer shall be required to add plant material within remaining buffers or elsewhere on the site.

Responsibility for installing buffers. The developing property shall always be responsible for providing required right-of-way and transition buffers. In those cases where a landscape buffer that complies with the right-of-way and transition buffer standards of this Section is already in place — whether on the site of the developing property or on the site of the adjacent property — the developer shall not be required to install another landscape buffer. The developer of a subdivision or other developing site shall only be responsible for ensuring that the intervening landscape buffer complies with the standards of this Section. Landscape buffers required for subdivisions shall be placed in easements.

Dumpster And Ground-Mounted Mechanical Equipment Screening. Dumpsters or other mechanically dumped trash receptacles located in "R-2" and more intensive districts shall be completely screened from view on all sides by a fence or wall with a minimum height of six (6) feet or one (1) foot taller than the dumpster or equipment, whichever is greater. The fence or wall shall provide complete visual screening of the dumpster or equipment and be compatible in material and color with the principal structure on the lot.

Landscape Material Standards. The following standards shall be considered the minimum required planting standards for all trees and landscape material.

Plant quality. Plants installed to satisfy the requirements of this Section shall conform to or exceed the plant quality standards of the most recent edition of American Standard for Nursery Stock published by the American Association of Nurserymen. Plants shall be nursery quality and indigenous or adapted to the local area. All plants shall be alive and in good health.

Artificial plants. No artificial plants or vegetation shall be used to meet any standards of this Section.

The placement location.

Section 405.250 Outdoor Lighting Standards.

[Ord. No. 1383 §607, 1-6-2003]

Purpose. The purpose of the exterior lighting standards of this Section is to regulate the spill over of light and glare on operators of motor vehicles, pedestrians and land uses near light sources. With respect to motor vehicles in particular, safety considerations form the basis of the regulations contained herein. In other cases, both the nuisance and hazard aspects of glare are regulated.

Applicability. The following standards shall apply to all exterior lighting except public street lighting and other lighting that is specifically exempted.

Flickering And Flashing Lights. No flickering or flashing lights shall be permitted.

Light Location. Light sources or luminaries shall not be located within required setback yard areas except on pedestrian walkways.

Maximum Illumination. The following table provides the standards for maximum illumination in a zoning district. The height limitations for each zoning district shall apply to the maximum height of luminaries.

Underlying Zoning District	Maximum Illumination (foot-candles)
Underlying Zoning District	Luminaries with no Cut-off	Luminaries with Total Cut-off Angle > 90°	Luminaries with Total Cut-off Angle < 90°
A, R-1, R-2, R-3	0.20	0.50	0.50
C-1, C-3	0.20	0.75	2.00
C-2	0.30	1.00	3.00
M-1, M-2	0.30	1.50	4.00

Exemptions. Because of their unique requirements for nighttime visibility and their limited hours of operation, ball diamonds, playing fields and tennis courts shall be exempt from the maximum illumination and luminaire height standards of this Section, provided that lights used for such activities shall not exceed a maximum post height of eighty (80) feet. Ball diamonds, playing fields and tennis courts may exceed a total cutoff angle of ninety degrees (90°), provided that the luminaire is shielded to prevent light and glare spill over to adjacent property zoned "R-2" or less intensive. The maximum permitted illumination at the lot line of "R-2" or less intensive property shall not exceed two (2) foot-candles.

Measurements.

Metering equipment. Lighting levels shall be measured in foot-candles with a direct-reading, portable light meter. The meter shall have a color and cosine-corrected sensor with multiple scales and shall read within an accuracy of plus or minus five percent (5%).

Method of measurement. The meter sensor shall be mounted not more than six (6) inches above ground level in a horizontal position. Readings shall be taken only after the cell has been exposed long enough to provide a constant reading. Measurements shall be made after dark when the light source in question is turned on, then when it is turned off. The difference between the two (2) readings shall be compared to the maximum permitted illumination and property line at ground level. This procedure eliminates the effects of moonlight and other ambient light.

Exterior lighting plan. At the time any exterior lighting is installed or substantially modified and whenever a building permit is sought in the "R-3" or more restrictive district or for a non-residential use in the "A-1" District, an exterior lighting plan shall be submitted to the Zoning Officer in order to determine whether the requirements of this Section have been met.

Section 405.255 Outdoor Storage and Display Standards.

[Ord. No. 1383 §608, 1-6-2003]

Standards For Outdoor Display In "C-1", "C-2", "C-3" And "M-1". The following standards shall apply to outdoor display areas in the "C-1", "C-2", "C-3" and "M-1" Districts when such display areas are not completely enclosed or completely screened from view.

Setback. Outdoor display areas shall comply with all exterior and interior setback requirements.

Height. Outdoor materials displayed shall not exceed fifteen (15) feet in height.

Standards For Outdoor Storage In "C-1", "C-2", "C-3" And "M-1". The following standards shall apply to outdoor storage areas in the "C-1", "C-2", "C-3" and "M-1" Districts when such storage areas are not completely enclosed or completely screened from view.

Setback. Outdoor storage areas shall comply with all exterior and interior setback requirements.

Height. The height of materials stored shall not exceed the height limitation of the underlying zoning district.

Section 405.260 Non-Residential Design Standards.
