PART 5
Design Standards
§ 500-112 Access to public streets.
This section sets forth vehicular access requirements for proposed site plans for developments which abut arterial, collector, and minor streets. This chapter recognizes that public streets are a public investment which require control mechanisms in order to assure both public safety and functional capacity. Proposed development for residential and nonresidential uses shall meet the following requirements:
A.
Access standards for all residential and nonresidential uses. All proposed site plans proposed for residential and/or nonresidential uses located in residential and/or nonresidential zoning districts shall meet the following standards:
(1)
Controlled access to public streets. Lot and parcel vehicular access points shall be permitted only at locations in accordance with this chapter and other Town of Barton adopted plans and ordinances. The Plan Commission may limit vehicular access to any adjoining arterial, collector, or minor street.
(2)
Distance between vehicular access points. The spacing of vehicular access points from arterial streets and highways to lots and parcels shall be determined as a function of arterial street and highway operating speeds. The minimum spacing between vehicular access points along such streets or highways shall be determined according to Table 500-112A. These spacings are based upon average vehicle acceleration and deceleration rates and are considered necessary to maintain safe traffic operation.

(3)
Limitation of access to interstate, United States, and state trunk highways. No new direct vehicular access shall be allowed to interstate, United States, and state trunk highway public rights-of-way unless approved by the Wisconsin Department of Transportation, Washington County, and the Plan Commission.
(4)
Temporary access.
(a)
Town streets. On Town streets, the Town Board may grant temporary access to properties and require their closure when access through adjoining properties is acquired upon recommendation by the Plan Commission. Such access shall be temporary, revocable, and subject to any conditions required and shall be issued for a period not to exceed 12 months.
(b)
County streets and highways. Temporary access to Washington County street and highway rights-of-way is reviewed and may be approved by the Washington County Highway Department. It is the applicant's responsibility to obtain all necessary approvals from the Washington County Highway Department for all such temporary access points proposed prior to site plan approval by the Town.
(c)
State highways. Temporary access to state highway rights-of-way is reviewed and may be approved by the Wisconsin Department of Transportation. It is the applicant's responsibility to obtain all necessary approvals from the Wisconsin Department of Transportation for all such temporary access points proposed prior to site plan approval by the Town.
(5)
Area circulation plan may be required. The Plan Commission may require the preparation of an area circulation plan for the proposed development covering several properties in an area surrounding a proposed site plan. The delineation of the area for the preparation of an area circulation plan shall be determined by the Plan Commission upon recommendation of either the Town Engineer or Zoning Administrator. Such a plan may require the sharing of access locations or temporary access. All landowners, except those with a previously approved site plan, shall be required to conform to such an area circulation plan once it is adopted by the Plan Commission as a component, or element, of the Town of Barton Comprehensive Plan. The Plan Commission may require that such an area circulation plan be prepared based upon the conduct of a traffic impact analysis conducted by a licensed professional engineer with expertise in traffic engineering. The Town Engineer and Zoning Administrator shall review all such studies and assist the Plan Commission.
(6)
Vehicular nonaccess reservations required. The Plan Commission may require deed restrictions to be placed on a lot or parcel for which a site plan is proposed in order to limit vehicular access to abutting arterial, collector, or minor streets and highways. A landscaped buffer yard of an adequate buffer yard intensity level, as determined by the Plan Commission or by Article XVIII of this chapter, shall be provided in vehicular nonaccess reservations along the property line abutting a public street right-of-way. In such situations, vehicular access to such lots may be provided by an abutting minor or collector street at designated access driveways. Such vehicular nonaccess reservations shall be graphically so noted on site plans or as a formal deed restriction formally filed with the Washington County Register of Deeds prior to their approval by the Town.
(7)
Arterial street and highway access and street intersections. No new direct public or private access shall be permitted to an arterial street or highway within 115 feet of the intersection of the right-of-way lines of another arterial street or highway; and, where lot or parcel size permits, no new direct public or private access shall be permitted to an arterial street or highway within 500 feet of the intersection of the right-of-way lines of another arterial street.
(8)
Minor streets and vehicular access point alignments. Minor streets and vehicular access points along both sides of a collector and/or arterial street shall be aligned to assist in reducing the number of driveways needed and to improve safety conditions related to access to the street system.
(9)
Sight distance and driveway placement. Direct vehicular access placement on abutting collector and arterial streets and highways shall be such that an exiting vehicle has a minimum unobstructed sight distance according to Table 500-112B based upon the operating design speed of the abutting collector or arterial street or highway.

Generally, along arterial streets and highways (including lots which abut the frontage roads of said rights-of-way), where the abutting street frontage is less than 400 feet, a maximum of one vehicular access point shall be permitted to a particular lot from each of any one or two abutting arterial streets and highways. One additional driveway entrance along a single continuous lot with frontage in excess of 400 feet may be permitted by the Plan Commission. When a shared vehicular access point is used by two or more abutting lots, said shared vehicular access point shall be considered as one single vehicular access point for each lot or parcel served.
(2)
Provision of shared vehicular access points between lots. Vehicular access points planned to be located along property lines, or within five feet of a property line, shall be shared vehicular access points with the abutting lot or parcel. The vehicular access point center line may be the property line between two lots or parcels of land or may be a mutually agreed upon land access easement.
(3)

The required snow storage area may be paved or not paved. In either case, adequate drainage of the snow storage area shall be provided to accommodate snowmelt, and no snowmelt shall drain on abutting properties.
(3)
Required setbacks, yards, and buffer yards may be used to accommodate the required snow storage area. However, areas landscaped with shrubs and/or trees shall not be used as snow storage areas.
§ 500-126 Applicability.
A.
Landscaping required. Landscaping is required in peripheral buffer yards, street buffer yards, for on-lot landscaping, in off-street parking areas, and in areas where vegetative mitigation (see § 500-111 of this chapter) is required. The area and/or length of each, as required herein, must be measured in order to determine the amount of landscaping required.
B.
Exemptions and modifications. All developments shall meet the provisions of this article, except as specifically exempted below:
(1)
Residential development on existing lots of record in the EA, AT, GA, HFA, R-1, R-2, R-3, R-4, R-5, R-6, R-7 and R-8 Districts. Residential development on existing lots of record in the EA, AT, GA, HFA, R-1, R-2, R-3, R-4, R-5, R-6, R-7 and R-8 Districts as of the date of the adoption of this chapter.
[Amended 4-19-2011 by Ord. No. 11-001]
(2)
Additions to existing buildings where the total floor area is not increased more than 10%. Additions to existing buildings where the total floor area is not increased more than 10% of the existing total floor area.
(3)
Additions to buildings which increase overall building area from 10% to 50%. Additions to buildings which increase their overall building area from 10% to 50% shall conform to the landscaping standards specified in this article to the maximum extent possible. All off-street parking areas and buffer yards shall conform to the landscaping requirements of this article. If insufficient dimensions exist on site, in order to achieve a sufficient level of landscaping, the standards set forth in this article may be reduced by up to 30% by the Plan Commission.
(4)
Floodplain, floodway, floodlands, and wetland areas. Areas located within floodplains, floodways, floodlands and wetlands are exempt from the landscaping requirements set forth in this article.
C.
Buffer yards to ameliorate nuisances between certain adjacent zoning districts. A buffer yard is a combination of a setback and a visual buffer or barrier and is a yard or area, together with the planting and/or landscape structure required thereon. The amount of land, the type of planting, and the amount of planting specified for each buffer yard requirement of this chapter are designed to ameliorate nuisances between certain adjacent zoning districts. Buffer yards are also designed to ensure a desired character along public streets and roads.
D.
Buffer yards required to separate different zoning districts. Buffer yards shall be required to separate different zoning districts from each other. Buffer yards function to eliminate or minimize potential nuisances such as dirt, litter, noise, glare of lights, signs, and unsightly buildings or parking areas or to provide spacing to reduce adverse impacts of noise, odor, or danger from fires or explosions.
§ 500-127 Standard plant units.
All landscaping requirements are stated in terms of the number of standard plant units required. This section defines the standard plant unit and its alternatives. All required landscaping shall conform to one or more of the plant unit alternatives of this section. The following Table 500-127 specifies the plant unit alternatives. In general, the five alternative plant mixes are interchangeable. In other cases, where a year-round variety is required, alternative Unit A is preferred and may even be specified by the Plan Commission. Where a year-round screen is required, Type D shall be used.

§ 500-129 General landscaping requirements.
[Amended 11-1-1995 by Ord. No. 95-2]
A.
Physical containment of landscaped areas. All landscaped areas located within or adjacent to a parking area or adjacent to a public street or sidewalk shall be designed to contain landscape materials and to prevent vehicular encroachment (i.e., through the use of continuous concrete curbing, railroad ties, headers, or depressed construction).
B.
Artificial landscape materials. Artificial trees, shrubs, turf, or plants shall not be permitted as landscaping.
C.
Ground cover. The use of landscape fabrics under all areas landscaped with nonliving materials, except those areas set aside for stormwater retention/detention, is recommended to prevent weed growth.
D.
Location. New vegetation shall be selected, planted, and maintained so that at maturity it will not interfere with utility lines, snow storage areas, vehicular parking, pedestrian circulation, traffic sight visibility at driveways and street intersections and will not cause damage or upheaval of sidewalks and pavement.
E.
Installation.
(1)
Timing of installation. Landscaping and watering devices shall be installed in accordance with the approved landscape plan prior to issuance of a zoning permit or commencement of operations. The Town of Barton will have the right to refuse approval of any project not meeting the provisions of this section.
(2)
Financial surety required. If approved landscaping and watering devices cannot be installed prior to occupancy or commencement of operations, a zoning permit may be issued by the Town of Barton if the applicant provides an acceptable form of surety meeting the requirements set forth in § 500-151 of this chapter. The application shall be accompanied by a complete estimate of the total cost of the approved landscaping and watering system improvements prepared by a landscape architect. All landscape materials shall be guaranteed for two years.
(3)
Return of financial surety. When it is determined that the landscaping and watering system have been installed in accordance with the approved plans, the Town of Barton shall return the surety to the applicant.
F.
Maintenance.
(1)
Responsibility for maintenance.
(a)
Maintenance of all landscaping shall be the responsibility of the owner, lessee, heirs, assigns, agents, homeowners' association, or other liable entity of the property and shall consist of regular watering, pruning, mowing, fertilizing, the removal and replacement of irrigation systems, and architectural features.
(b)
The owner or liable entity in control of any private premises shall at all times maintain the premises free of litter and weeds.
(2)
Landscape phasing. Future building pads within a phased development shall be maintained in a dust-free condition vegetated with ground cover.
(3)
Plant replacement. Any plant materials included in an approved landscaping plan that do not survive a plant establishment period of two years after installation shall be replaced with plant material(s) of the same or like species of equal size within the next planting season, but in any event, within six months of the plant's demise. Said replacement shall be made by the property owner or, in the case of landscape plant materials located within a landscape easement under the control of a homeowners' association, the homeowners' association shall be responsible for said replacement.
§ 500-130 General buffer yard requirements.
A.
General.
(1)
Buffer yard standards are listed in this section for peripheral buffer yards and for street buffer yards.
(2)
Peripheral and street buffer yard standards are based on a required buffer yard intensity factor value. A variety of combinations of buffer yard width, planting intensity, and structural options (i.e., fences and earthen berms) may be selected from Table 500-134 to reach the required buffer yard intensity level value.
(3)
Peripheral buffer yards shall be located along the outer perimeter of a lot or parcel and shall extend to the lot or parcel boundary line. Peripheral buffer yards shall not be located on any portion of an existing or dedicated public or private street or right-of-way.
(4)
Required buffer yard plantings may be planted in natural-appearing groupings along the total length of the buffer yard and need not be spaced uniformly along said total buffer yard length.
B.
Plant materials.
(1)
For each buffer yard listed, a specific combination of canopy, shade, and understory trees, evergreen trees, and shrubs is required as indicated in § 500-127.
(2)
All buffer yard areas shall be seeded with lawn or native ground cover, unless such vegetation is already fully established.
(3)
The exact placement of required plants and structures shall be the decision of the property developer.
C.
Fences. Fences shall be constructed of rock, masonry, or wood. Chain-link fences and chain-link with slats shall be prohibited from use in required buffer yards. All fences used shall also meet the requirements for the construction of fences as set forth in Article XI of this chapter.
D.
Height of required vegetation. Height of vegetation selected for required buffer yards shall be measured from the highest finished adjacent grade of the element to be screened.
E.
Berming. Earthen berms shall be designed to transition to existing grades, not to exceed a slope ratio of 2:1, and shall be covered with plant material, ground cover, or partially riprapped to prevent erosion. Berms with vegetative cover shall be designed to retain irrigation water rather than encourage runoff. All earthen berms shall be safely designed in order to accommodate mowing when needed.
F.
Calculation of buffer yard requirements.
(2)
Buffer yard standards listed in this section are to be calculated for every 100 linear feet of peripheral lot line boundary and/or street frontage present on a given lot.
(3)
In instances where the zoning district boundary and/or street frontage is less than 100 feet, the required buffer yard planting shall be one plant unit. (See Table 500-127.)
(4)
To determine the type of buffer yard required on a parcel, between two parcels or lots, or between a parcel or lot and a street, the following procedures shall be used:
(a)
Procedures for determining minimum required peripheral buffer yards:
[1]
Identify whether any portion or property line of the parcel or lot coincides with a zoning district boundary. If it does, determine the abutting zoning districts on both sides of the property line.
[2]
Refer to § 500-132 to determine the required buffer yard intensity factor needed to be achieved between the two zoning districts.
[3]
Based upon the buffer yard intensity factor required, refer to the applicable Table 500-134A to 500-134E to select the minimum number of plant materials (per 100 feet of buffer yard length), the buffer yard width, and required structure type combination by selecting the desired alternative buffer yard type.
[4]
Calculate the actual number of plants required by selecting the minimum number of plant materials (per 100 feet of buffer yard length) from the alternatives indicated the applicable Table 500-134A to 500-134E and multiply by the hundreds of feet of buffer yard to be planted. Calculations resulting in fractional numbers of plant materials required shall be rounded to the next higher whole number.
§ 500-131 Limitations on buffer yard use.
§ 500-132 Peripheral buffer yards between zoning districts.
The minimum required buffer yard intensity level factor values for peripheral buffer yards between zoning districts set forth in the Table 7 at the end of this chapter refer to the buffer yard width and plant unit standards set forth in Table 500-134 of this article. Peripheral buffer yards are required between adjacent zoning districts. The abbreviations used in Table 7 represent the Town of Barton zoning district designations used throughout this chapter.
§ 500-133 Street buffer yards.
[Amended 4-19-2011 by Ord. No. 11-001; 10-21-2014 by Ord. No. 14-003]
The numbers given in Table 500-133 refer to the various buffer yard intensity level factors described in Table 500-134 of this chapter. Any combination of vegetation, structure(s), and width set forth in Table 500-134 may be selected, provided the required buffer yard intensity level factor is met as required by § 500-132 of this chapter. The abbreviations used in Table 500-133 represent the Town of Barton zoning district designations used throughout this chapter.

B.
Existing vegetation may count towards the provision of minimum off-street parking landscape requirements. Existing trees that can be preserved, where grading does not cut them off from a reasonable supply of water and where the area under the canopy remains undisturbed, shall count towards the plant requirements by measuring the area of the island. The minimum size of such an island shall be 300 square feet. Table 500-135A specifies the minimum area requirements per 24 required off-street parking spaces or fraction thereof.
C.
Curbs, barriers, and overhangs required to contain landscape areas. The curb or barrier around landscape areas may be utilized as a wheel stop, provided the area of vehicle overhang does not exceed two feet and does not damage or interfere with the landscaping. Where vehicle overhangs abut required landscape areas, a minimum five-foot-wide planter is required for a single vehicle overhang and an eight-foot-wide planting area is required for a double vehicle overhang. Vehicle overhang into the public right-of-way is not permitted.
D.
Uses not permitted in required landscaped areas. Parking (except where vehicle overhang is permitted), buildings, and display of equipment or vehicles are not permitted in required landscaped areas.
E.
Required landscape materials not to constitute a driving hazard. To ensure that landscape materials do not constitute a driving hazard, trees used to landscape parking islands shall have a clear trunk height of six feet; mature shrubs, ground cover, or other landscaping material shall not exceed three feet in height. The landscaped area within these planters may be used to satisfy, to the extent provided, the landscaping requirements.
§ 500-136 Minimum standards for parcels and lots.
A.
Minimum on-site landscaping required. Each residential and nonresidential zoning district or lot in a new development shall contain a minimum amount of landscaping in areas not designated as off-street parking under the provisions of §§ 500-117 and 500-135, buffer yards under §§ 500-130 through 500-134 of this chapter, or areas designated as buildings. For each acre of land not occupied by buildings, off-street parking areas, drives, or buffer yards, the number of Type B plant units as described in Table 500-127 shall be planted. In the case of residential buildings, the requirement shall be for every parcel, lot, or dwelling unit, whichever results in a greater amount of plant materials.
B.
Deed-restricted open space and undisturbed resource protection areas excluded. No area that is undisturbed and designated as open space required under the open space or natural resource protection provisions of this chapter, and other deed-restricted residential open space meeting open space ratio (OSR) requirements of this chapter, or is designated as an undisturbed resource protection area and protected by deed restrictions, shall be included in the calculation of the area to be planted.
C.
Minimum required on-site landscaping. For residential and all nonresidential zoning district parcels and lots, the minimum amount of on-site landscaping set forth in Table 500-136C shall be provided in addition to all other required buffer yard landscaping and off-street parking landscaping.

§ 500-139 Mitigation requirements.
The Town of Barton recognizes that the use of the landscape surface ratio (LSR) standards for the provision of adequately landscaped open space in nonresidential areas as set forth in this chapter may not always lead to good design and, under some circumstances, may be difficult to achieve. This section addresses landscape mitigation measures which may be allowed by the Plan Commission.
A.
Mitigation of required buffer yards and off-street parking landscaping not permitted. The mitigation of the dimensional requirements, structural requirements, and/or landscape plant unit and/or material requirements of required peripheral or street buffer yards shall not be allowed. Landscape surface ratio (LSR) mitigation shall only be allowed for required on-site landscaping as required in Table 500-136C.
B.
Maximum allowable reduction of the landscape surface ratio (LSR) through mitigation measures. The maximum allowable reduction of the landscape surface ratio (LSR) through mitigation measures shall not fall below those landscape surface ratios (LSRs) set forth in Table 500-139. In no case shall reductions in landscape surface ratios (LSRs) supersede the natural resource protection standards set forth in Article XV or allow for increases in either the maximum gross floor area ratio (GFAR) or net floor area ratio (NFAR) set forth in the various zoning district requirements of this chapter.

§ 500-141 Exterior lighting plan required.
A.
General. At the time any exterior light is installed or substantially modified, and whenever a zoning permit application is made, an exterior lighting plan shall be submitted to the Town of Barton in order to determine whether the requirements of this section have been met and that adjoining property will not be adversely impacted by the proposed lighting.
B.
Lighting plan elements. A lighting plan submitted pursuant to this chapter shall have, at a minimum, the following elements:
(1)
A catalog page, cut sheet, or photograph of the luminaire, including the mounting method.
(2)
A photometric data test report of the proposed luminaire graphically showing the lighting distribution at all angles vertically and horizontally around the luminaire.
(3)
A plot plan, drawn to a recognized engineering or architectural scale, indicating the location of the luminaire(s) proposed, mounting, and/or installation height in feet, the overall illumination levels (in footcandles) and uniformities on the site, and the illumination levels (in footcandles) at the property boundary lines. This may be accomplished by means of an isolux curve or computer printout projecting the illumination levels.
(4)
A graphic depiction of the luminaire lamp (or bulb) concealment and light cutoff angles.
§ 500-142 Exterior lighting for specified outdoor recreational uses.
Ball diamonds, playing fields, golf driving ranges, tennis courts, and similar outdoor recreational facilities have unique requirements for nighttime visibility and generally have limited hours of operation. These uses may be exempted from the exterior lighting standards of this article if the applicant can satisfy the Plan Commission, upon site plan review, that the following requirements are met:
A.
Site plan. The site plan must meet all other requirements of this article and chapter; and
B.
Exterior light sources. Any exterior light sources shall not exceed the maximum permitted post height of 50 feet; and
C.
Shielded luminaires. If the luminaire is shielded in either its orientation or by a landscaped buffer yard to prevent light and glare spillover to adjacent residential property(ies) or residential zoning districts, then the luminaire may exceed a total cutoff angle of 90°. The maximum permitted illumination at the interior buffer yard line of all required buffer yards shall not exceed two footcandles; and
§ 500-143 Streetlighting.
Streetlighting shall conform to the standards set forth by the State of Wisconsin for state trunk highways, Washington County for county trunk highways, and the Town of Barton for Town streets and highways.
§ 500-144 Searchlights.
The Zoning Administrator may permit the temporary use of a searchlight for advertising purposes in any nonresidential zoning district, provided that the searchlight will not be located in any public right-of-way, will not be located closer than 10 feet to an adjacent property, and will not cause a hazard to traffic or adjoining properties. Searchlight permits shall not be granted for a period of more than five days in any six-month period.
§ 500-145 Additional regulations.
Notwithstanding any other provision of this article to the contrary, the following provisions shall also be applicable:
A.
Flickering and flashing lights. No flickering or flashing lights shall be permitted (excluding seasonal lighting between November 1 and January 31).
B.
Light sources and/or luminaires not to be located within required buffer yards. Light sources or luminaires shall not be located within required buffer yard areas except on pedestrian walkways.
C.
Requirements of other applicable codes and ordinances to be met. The provisions of this article are designed to supplement other applicable ordinances and codes and not as a substitute. All outdoor electrically powered illuminating devices shall be installed in conformance with the provisions of this chapter, applicable building codes and ordinances, electrical codes and ordinances, and all other codes and ordinances as applicable and under appropriate permit and inspection.
§ 500-146 Light measurement.
A.
Metering equipment. Lighting levels shall be measured in footcandles with a direct-reading, portable light meter. The meter shall be read within an accuracy of plus or minus 5%. It shall have been tested, calibrated, and certified by an independent commercial photometric laboratory or the manufacturer within 30 days of its use.
B.
Method of measurement. The meter sensor shall be mounted not more than six inches above ground level in a horizontal position at the interior line of the buffer yard or at the property line, as required herein. Readings shall be taken only after the cell has been exposed long enough to provide a constant reading. In order to eliminate the effects of moonlight and other ambient light, measurements shall be made after dark with the light source in question on, then with the same sources off. The average of the two readings shall be compared to the maximum permitted illumination allowed under this article.
