Document: Neighborhood Conservation - County (NC-TC) Zone

Access to Lots

• Safe and adequate access must be provided to all areas of the proposed development.
• Access can be provided directly or indirectly by a public right-of-way, private vehicular or pedestrian way, or commonly owned easement.

RA 6/3 Minimum Lot Size

• Groundwater testing to determine the minimum lot size should be performed during high groundwater season.
• Regardless of groundwater testing results, an amendment of the Official Zoning Map according to Sec. 8.7.2. is required before approving a lot size of less than 6 acres.

Subdivision of Hillsides

Lands having slopes of 10% or greater shall use the following procedure to calculate the maximum density allowable.

• Prepare a contour map at a vertical interval of not more than 5 feet, or not more than 10 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.
• From the contour map, prepare a slope map using the following slope classifications:
• Slope Range 0% - 10%, Land Use Classification RA-3
• Slope Range 10% - 15%, Land Use Classification RA-5 and RA 7.5
• Slope Range 15% - 30%, Land Use Classification RA-10
• Slope Range 30% and greater, Land Use Classification RA-20
• 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.
• The total number of proposed lots shall not exceed the base density allowable based on the slope map information.
• 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.

Subdivision - Double or Reverse Frontage

Double or reverse frontage lots or buildings shall be prohibited, except where necessary to limit vehicular access to arterial roads or highways; or to provide separation of development from through traffic; or to overcome specific disadvantages of topography or other natural features of the site.

Subdivision - Combination to Increase Density

Lots of record may not be combined with other lots of record for the purpose of subdividing to increase density. However, subdivision for other purposes where overall existing densities are retained or reduced shall be permitted.

Accessory Residential Units

Accessory residential units are only allowed in association with a primary residential use.

Additional Zone-specific Standards - Maximum Site Development

The maximum site development of a single-family unit, including associated accessory structures, is calculated using the following formulas:

• For ASA ≤ 0.1 ac, Maximum Site Development (sf) = (ASA)(0.6)(43,560).
• For ASA 0.1-0.5 ac, Maximum Site Development (sf) = (ASA-0.1)(0.31)(43,560)+2,614.
• For ASA 0.5-3 ac, Maximum Site Development (sf) = (ASA-0.5)(0.11)(43,560)+8,015.
• For ASA 3-35 ac, Maximum Site Development (sf) = (ASA-3)(0.040344)(43,560)+19,994.
• For ASA > 35 ac, Maximum Site Development (sf) = (ASA)(0.05)(43,560).

Certain elements are exempt from the calculation of maximum site development:

• Public and neighborhood pathways, flood control levees, ponds.
• Outdoor riding arenas on properties 6 acres or larger. To be exempt, the riding arena must be an uncovered area no larger than 160 feet by 200 feet, constructed of natural materials, without bleachers, and with 12 foot wide gates at 2 ends that must remain open for wildlife movement when not in use.

In certain subdivisions, the result of the above calculation is further multiplied by a specific factor to determine the maximum site development:

• Subdivision Ellen Creek, Multiplier 1.23.
• Subdivision Jackson Hole Golf and Tennis Club, Multiplier 1.17.
• Subdivision NC-TVSF, Multiplier 1.44.
• Subdivision Spring Creek Ranch, Multiplier see PUD.
• Subdivision Teton Pines (JH Racquet Club Resort), Multiplier see PUD.

Additional Zone-specific Standards - Maximum Floor Area

The maximum floor area of a single-family unit, including associated accessory structures, is calculated using the following formulas. Basements are excluded from maximum floor area calculations. Maximum Scale of Development Standards still apply.

• For BSA ≤ 0.11 ac, Maximum Floor Area (sf) = (BSA)(0.43)(43,560).
• For BSA 0.11-0.172 ac, Maximum Floor Area (sf) = (BSA-0.11)(0.2833)(43,560)+2,060.
• For BSA 0.172-0.5 ac, Maximum Floor Area (sf) = (BSA-0.172)(0.124)(43,560)+2,825.
• For BSA >0.5 ac, Maximum Floor Area (sf) = (BSA-0.5)(0.032)(43,560)+4,596.

In certain subdivisions, the result of the above calculation is further multiplied by a specific factor to determine the maximum floor area:

• Subdivision Ellen Creek, Multiplier 1.35.
• Subdivision Jackson Hole Golf and Tennis Club, Multiplier 1.15.
• Subdivision NC-TVSF, Multiplier 1.4.
• Subdivision Spring Creek Ranch, Multiplier see PUD.
• Subdivision Teton Pines (JH Racquet Club Resort), Multiplier see PUD.
