RURAL AREA ZONES
Division 3.1.- All Rural Area Zones
Rural area zones are intended to preserve wildlife habitat, habitat connections, scenic vistas, and undeveloped open spaces to the extent possible, given existing development patterns. There are two types of rural area zones.
3.1.1. - Character Zones.
Character zones, established in Division 3.2, are character-based and established to implement the Comprehensive Plan. As described in the Comprehensive Plan, rural areas provide: wildlife habitat, scenery, open space, an abundance of landscape, limited detached single-family development, and minimal nonresidential development. The rural area character zones represent a continuum of rural character as follows:
A.
Rural-1 (R-1) generally encompasses the largest holdings with the most potential for use as sites of greater than 70 acres that provide undeveloped habitat, scenery, and open space.
B.
Rural-2 (R-2) generally encompasses large parcels that are not in larger holdings, mostly in the 3—70 acre range, where site design is the focus of habitat, scenery and open space conservation efforts.
C.
Rural-3 (R-3) generally encompasses rural subdivisions and neighborhoods with lots sizes of six acres and less where rural character is defined by single-family neighborhoods and conservation is focused on wildlife permeability.
(4/1/16)
3.1.2. - Legacy Zones.
Legacy zones, established in Division 3.3, are carried forward from the previous LDRs, and it is the intent that they will be phased out over time as character zones are adopted and applied. The legacy zones include:
A.
Business Conservation - County (BC-TC)
B.
Mobile Home Park - County (MHP-TC)
C.
Neighborhood Conservation - County (NC-TC)
D.
Suburban - County (S-TC)
E.
Rural - County (R-TC)
(4/1/16)
3.2.1. - Rules Applicable to All Rural Area Character Zones.
A.
Rules of Measurement.
1.
Gross Site Area. All measurements in the rural character zones shall use Gross Site Area instead of Base Site Area or Adjusted Site Area.
B.
Sites with Multiple Lots of Record. Sites comprised of multiple lots of record in the rural character zones shall meet the following standards.
1.
Agriculture Exempt. These standards, of this Section 3.2.1(B), shall not apply to agriculture use, physical development associated with agriculture use, and utilization of agriculture exemptions.
2.
Design as a Single Site. A site comprised of multiple lots of record shall be reviewed as a whole for purposes of determining the most appropriate location for development or use.
3.
Restriction Required. Area required to entitle physical development or use that is on a lot of record other than the primary lot of record of the physical development or use shall meet the following standards.
a.
It shall be restricted through an instrument approved by the County Attorney and recorded against the lot of record.
b.
The restriction shall terminate if the physical development is removed or the use is abandoned.
(1/23/23)
3.2.2. - Rural-1 (R-1).
A.
Intent.
1.
Desired Future Character. Development, use, and conservation that occurs in the R-1 should be located and designed to allow for property rights in a way that substantially protects wildlife habitat, habitat connections, and scenery, and preserves the historic western character of the community by supporting the continuation of agriculture. Development and use that result in better conservation of wildlife habitat, scenery, and agriculture than can be achieved by single-family development of 35-acre parcels is encouraged.
2.
Existing Character. The R-1 zone generally consists of large holdings outside of complete neighborhoods where the opportunity exists for use of property in sites that are greater than 70 acres even if property rights allow use of the property as multiple smaller sites.
3.
Comprehensive Plan. The R-1 zone is based primarily on the vision for preservation subareas identified in the Illustration of Our Vision chapter of the Comprehensive Plan.
B.
Physical Development. Standards applicable to physical development are provided in this subsection. Where a cross-reference is listed see the referenced division or section for additional standards. All standards in Article 5 are applicable unless stated otherwise.

c.
A single building shall not exceed 50,000 square feet.
d.
The equestrian center shall still be subject to the floor area maximum.
2.
Conditional Principal Uses.
a.
Compatibility. The compatibility of one or more principal conditional uses on a site shall be defined through the CUP review. In evaluating whether a particular use is appropriate, the Board shall consider the following:
i.
The extent to which the proposed use promotes or sustains the site's open space; and
ii.
The cumulative impact of all permitted uses and development options on the site's open space, as compared to the use of the site at its base residential density.
b.
Prohibited in the High-Tier of the NRO. The following conditional uses permitted in the R-1 zone are prohibited within the High-Tier of the NRO:
i.
Campground
ii.
Assembly
iii.
Daycare/Education
iv.
Aviation
c.
Maximum Intensity of Use. The intensity of the use shall be limited to maintain the rural character of the area and the State or County road from which access is taken. If the proposed use is of a continuous nature, the intensity shall be limited by restricting the maximum occupancy. If the proposed use involves discrete occurrences, the intensity shall be limited by restricting the frequency of occurrence. Depending on the nature of the use, the Board shall impose conditions based on one or both of the standards below:
i.
Maximum Occupancy. The Board shall establish a maximum occupancy to protect community character.
a)
The maximum occupancy shall not result in a change in the classification of the road from which access is taken.
b)
The maximum occupancy may be exceeded for discrete occurrences, pursuant to the standards of Subsection E.2.c.ii below.
c)
The Board may impose a maximum occupancy restriction that is stricter than the limits established in the standards above to mitigate potential impacts other than traffic, such as impacts to wildlife. Stricter standards may be imposed on a seasonal or periodic basis.
EXAMPLE:An Education/Daycare use that takes access from a major collector road may be limited to a certain number of students based on projected traffic counts to ensure the additional traffic does not result in a change in classification of the road to an arterial, In another case the Board might establish a lower number of guests for an Outfitter/Tour Operator in the winter season, to avoid impacts to crucial wildlife winter range.
ii.
Frequency. If the proposed use involves discrete occurrences, the Board shall limit the frequency of occurrence to protect community character. The Board may limit the number of overall occurrences in a year, or the number and frequency of occurrences during a specific season or time period.
a)
Total Occurrences. The total number of discrete events or occurrences, defined as being no more than one calendar day in duration, shall not exceed 30 per year.
EXAMPLE:The Board might choose to limit the number of events held at an athletic field in order to reduce the frequency and duration of adverse impacts to neighbors.
b)
Traffic Demand Management. The applicant shall demonstrate traffic demand management to maintain the rural character of the area and the access to the use.
iii.
Seasonal Limitations. The Board may limit a use to a particular season or time period. If a Natural Resources Assessment was prepared in advance of the project, the Board shall consider the recommendations of the NRA in establishing seasonal limitations.
EXAMPLE:On a property with crucial wildlife winter range, the Board might limit the use to times when winter range is not crucial to wildlife.
iv.
Use areas. Proposed outdoor or temporary storage or use areas, such as tents, shall be evaluated as part of the CUP process, and conditions may be imposed to minimize impacts.
EXAMPLE:The Board might impose a condition that limits the number of hours or days during which a reception tent can be on site.
d.
Setbacks and Location.
i.
Uses shall be clustered adjacent to an existing ranch compound or physical development, unless the applicant can demonstrate to the satisfaction of the Board that either,
a)
The proposed use is dependent on or requires location adjacent to a natural feature; or
b)
An alternate location on the property better sustains or promotes the open space of the property or minimizes potential impacts to neighboring properties.
EXAMPLE:A boat ramp is a water dependent use that must be located adjacent to the river to be functional, thus it could be permitted in a location that is not clustered against existing physical development.
ii.
Setbacks for the use shall be established through the CUP process, and may vary for daily staff functions and public events, and between indoor and outdoor activities.
EXAMPLE:For an Outdoor Recreation use, the Board might establish a 300' setback from a property line shared with a residential use to minimize impacts, but allow a 0' setback from a property line shared with public lands.
e.
Hours of Operation.
i.
Outdoor Use Setback Less than 300 Feet. An outdoor public event that is located less than 300 feet from a property line, which is adjacent to an occupied or vacant residential site that is not part of the conditional use, shall be limited to hours of operation of 9:00 a.m. to 9:00 p.m. Hours of staff activities shall be established through the CUP process.
ii.
Other Uses. Uses other than those regulated by Subsection e.i above, shall be limited to the following hours of operation:
a)
Daycare and Education 7:00 a.m. to 10:00 p.m.
b)
Dude Ranches, Campgrounds, and Hospitals, 24-hour operations with curfew hours set during the CUP process.
c)
All other conditional principal uses allowed in the Use table shall be limited to the hours of 9:00 a.m. to 11:00 p.m.
d)
Hours of Staff activities for all conditional principal uses shall be established through the CUP process.
iii.
Music. All music shall end no later than 10:00 p.m.
iv.
The Board may establish separate hours of operation that are more strict for amplified music or sound associated with the use.
v.
The Board may impose hours of operations that are more strict than those established above should site-specific or neighborhood conditions warrant additional limitations.
EXAMPLE:For an outdoor recreation use that involves outdoor receptions, the Board may choose to limit the hours of operation to 9:00 a.m. to 9:00 p.m. for the use, but condition that amplified music or sound end earlier, at 8:00 p.m.
f.
Parking. All standards of Division 6.2 shall apply, except that Commercial uses subject to this Subsection shall be exempt from Section 6.2.5(A.2).
g.
Access. Uses subject to the standards of this Subsection shall be exempt from Section 7.6.2(C.1), provided all other standards of Division 7.6 are met and the access is approved by the Fire Marshal.
3.
Campgrounds. In addition to the standards applicable to all campgrounds established in Section 6.1.5(D), campgrounds in the R-1 district are subject to the following:
a.
Ratio of Site Types. In order to maintain a variety of camping options, the ratio of tent sites to RV sites shall be at least 1:3.
4.
Accessory Heavy Retail/Service and Light Industrial Uses. Heavy Retail/Service and Light Industrial uses are permitted in the R-1 zone subject to the following:

b.
The proposed use shall comply with the standards in Section 3.2.2(E.2) above.
5.
Existing Landing Strips. The existing Fall Creek Ranch and Melody Ranch landing strips shall be considered conforming without a CUP. A CUP shall only be required upon 20% expansion of the use that existed on January 1, 2015.
6.
Accessory Residential Unit (ARU).
a.
Primary Use Residential.
i.
Maximum Scale. An ARU accessory to a residential use shall not exceed 1,000 sf of gross floor area including basement floor area.
ii.
Density. A maximum of one ARU shall be permitted accessory to a detached single-family unit.
b.
Primary Use Not Residential.
i.
Unit Type. The following residential uses are permitted as unit types for an ARU associated with a primary nonresidential use:

Detached single-family
b)
Apartment
c)
Mobile Home
d)
Dormitory
ii.
Density/Intensity.
a)
850 SF Units. The number of ARUs with habitable floor area of 850 sf or less is limited only by the requirement that the ARUs be accessory to the principal use.
b)
Larger Units. A maximum of one ARU larger than 850 sf of habitable floor area is allowed per 35 acres of gross site area of nonresidential use. This allowed ARU density is in addition to the base density of allowed principal residential use.
c)
Floor Area Exempt. Floor area in an ARU accessory to a non-residential use is exempt from maximum floor area calculations.
EXAMPLE:A 140-acre site in agriculture is entitled to four detached single-family units (140/35=4) as well as four ARUs accessory to the agriculture use (140/35=4) that are greater than 850 sf of habitable floor area. The site would also be allowed additional ARUs less than 850 sf of habitable floor area, determined to be secondary and subordinate to the principal use. The floor area in the ARUs would not count against the maximum floor area of 42,688 sf allowed on 140 acres.
iii.
Occupancy of Larger Units. An ARU larger than 850 sf shall meet the following occupancy standards.
a)
The occupant of the ARU shall be employed by the operator of the nonresidential use and work in the nonresidential use at least 20 hours per week for a minimum of three months a year. In addition, the immediate family of the occupant may also reside in the residential unit.
b)
When not occupied by an employee of the nonresidential use, the ARU may be rented to others. Such rental shall be for a period of at least 31 days.
7.
Nonhabitable Floor Area Exemption for Historic Structures. Nonhabitable floor area shall be exempt from maximum floor area if the floor area is in a building that meets all the following standards.
a.
The building is included on the Teton County Historic Preservation Board (TCHPB) list of historically significant properties or is otherwise deemed in writing by the TCHPB to be historically significant.
b.
The building is located at its original site. A building is at its original site if it is within the development area that existed during the building's period of historical significance, as found by the TCHPB in its determination of historical significance. The building may be moved within the current parcel boundaries of the original site.
c.
Modifications to the building shall be approved by the TCHPB in order to retain the exemption.

3.2.3. - Rural-2 (R-2).
A.
Intent.
1.
Desired Future Character. Development, use, and conservation that occurs in the R-2 should be located and designed to allow for property rights in a way that substantially protects wildlife habitat, habitat connectivity, and scenery, and preserves the historic western character of the community by supporting the continuation of agriculture. Existing property rights define the maximum density of the R-2 and clustering of development and combination of lots is encouraged. Residential and/or agricultural use is preferred, but institutional uses with a rural character that require a large site may be compatible.
2.
Existing Character. The R-2 zone generally encompasses large parcels, not in larger holdings, mostly in the 3—70 acre range, used for a single-family dwelling.
3.
Comprehensive Plan. The R-2 zone is based primarily on the vision for conservation subareas identified in the Illustration of Our Vision chapter of the Comprehensive Plan.

Subdivision of Hillsides. Lands having slopes of 10% or greater shall use the following procedure to calculate the maximum density allowable.
a.
Prepare a contour map at a vertical interval of not more than five feet, or not more than ten feet where the natural slope exceeds 15%. The map shall be certified as complying with the following standard of the United States National Map Accuracy standard, revised June 17, 1947, by the registered land surveyor or registered engineer presenting or preparing the map: "Vertical accuracy, as applied to contour maps on all publication scales, shall be such that not more than 10% of the elevations tested shall be in error more than one-half the contour interval. In checking elevations taken from the map, the apparent vertical error may be decreased by assuming a horizontal displacement within the permissible horizontal error for a map of that scale."
b.
From the contour map, prepare a slope map using the following slope classifications:
c.
From the slope map, measure the acreage in each slope range and divide by the minimum lot size of the corresponding land use classification (RA-3, RA-5, RA-7.5, RA-10, RA-20) to establish the density allowed for each slope range. The base density allowed for a lot of record shall be the sum of the number of dwelling units allowed for the slope ranges.
EXAMPLE:Assuming there are 100 acres to be subdivided, the formula for ascertaining maximum density in each classification would be as follows:
15 acres RA-3 = 15 divided by 3 = 5 dwelling units
10 acres RA-5 = 10 divided by 5 = 2 dwelling units
15 acres RA-7.5 = 15 divided by 7.5 = 2 dwelling units
20 acres RA-10 = 20 divided by 10 = 2 dwelling units
40 acres RA-20 = 40 divided by 20 = 2 dwelling units
d.
The total number of proposed lots shall not exceed the base density allowable based on the slope map information.
e.
A lot in a proposed subdivision shall contain at least 0.8 of a dwelling unit according to the slope analysis; the overall number of subdivision lots, however, shall not exceed the total number of dwelling units for the entire lot of record upon which the subdivision is proposed.
6.
RA 6/3 Minimum Lot Size. All groundwater testing to determine the minimum lot size shall be performed during high groundwater season. Notwithstanding the results of groundwater testing, an amendment of the Official Zoning Map pursuant to Section 8.7.2 shall be required prior to the approval of a lot size of less than six acres.
7.
Access to Lots. Safe and adequate access shall be provided to all areas of the proposed development, either directly or indirectly, by a public right-of-way, private vehicular or pedestrian way, or commonly owned easement.
