§ 18.45.050 Area requirements.
(1)
Parcel Size. Each application pursuant to this chapter shall be for a site of not less than one and a half acres and not more than 15 acres. The city council may approve zoning and development under the RM-6 zone on parcels of at least one-half acre where such parcels have frontage onto a major street and where such use is in compliance with the Riverton City general plan and with the surrounding properties.

(Ord. 21-28 § 1 (Exh. A); Ord. 25-21 § 1 (Exh. A))
§ 18.45.070 Lots located on private roads.
(1)
Public Street Systems Encouraged. Public street systems are encouraged for access to all residential dwelling sites. However, the city recognizes there are cases where it is impossible or impractical to develop using city standard public streets. In these situations, a conditional use for a private road may be approved by the planning commission.
Subdivisions utilizing private roads may be developed in the RM-6 residential zone where at least two of the following conditions exist (subsections (1)(a) or (1)(b) and (1)(c) of this section):
(a)
A lot of record which is preexisting and has no frontage or adequate property to construct a public street; or
(b)
It can be demonstrated by the applicant that the property cannot be physically subdivided with public streets, and that development on a private lane would not impede the extension of any adjacent public right-of-way either now or in the foreseeable future; and
(c)
The development does not impede the necessary access from adjoining properties as required by the master transportation plan.
(2)
Private roads shall be of sufficient design to service the projected use of property and the projected use of adjoining properties that may have access across such private rights-of-way. The commission may require developments utilizing private roads to set aside right-of-way or build roadway improvements to connect to other properties currently zoned RM-6, and to properties that could potentially be zoned RM-6 in the future.
(3)
Private roads shall be fully improved with asphalt or concrete to adopted city standards. Curb, gutter or other appropriate storm drainage methods may be required, as approved by the city based upon city engineer's recommendation. All portions of private rights-of-way shall accommodate a street of no less than the standards as listed subsequently:
(a)
One to two lots: 20 feet of paved surface width.
(b)
Three or more lots and/or a lane that exceeds 150 feet in length: 26 feet wide paved surface minimum. The land use authority may require additional right-of-way width, and additional surface improvements up to the minimum city standards for rights-of-way and street design. In these cases, the land use authority may consider the context, number of proposed lots, possible future connections of private roads, guest parking, pedestrian safety, emergency access, traffic impacts and overall livability of the proposed development when determining the private lane width and design.
(d)
Development of additional lots on an existing private lane shall be allowed only where the lane meets the width requirements for the proposed number of lots.
(4)
Private road improvements shall include a strategically located turnaround to accommodate emergency vehicles. At a minimum the turnaround may be in any configuration which complies with the applicable fire codes, as determined by the fire marshal or designee. Additional turnaround area may be required by the land use authority to accommodate emergency vehicle access.
(5)
The maximum number of units allowed in a development will be established in the review of the conditional use permit for the private road, based on criteria including but not limited to: required minimum lot sizes, traffic and access management on the private lane and on adjacent or nearby public streets, emergency service's needs, and available lane widths.
(6)
All necessary public utility easements shall be dedicated on all lots, including full access where required by city officials or workers.
(7)
Minimum yard setback requirements as defined for public streets shall apply to all buildings and uses adjoining private roads and private rights-of-way, with setbacks measured from the nearest edge of the private road.
(8)
No portion of a private road may be counted towards the required lot size.
(9)
No portion of a private road may be counted towards the required driveway dimensions on individual lots.
(10)
All lots on private roads shall be provided with standard city utility connections.
(11)
Private roads shall be named and identified by street signs which meet Riverton City standards. Street signs must be installed by the developer prior to the issuance of building permits.
(12)
Private roads shall connect to public roads with a drive approach that meets Riverton City standards.
(13)
A recorded binding covenant shall be prepared providing for the maintenance of the private roads, shared private drainage structures, and any other common improvements.
(14)
Easements across private property in another ownership may be allowed to accommodate a private road only if the property to be accessed is landlocked, with no other means of access available, now or in the foreseeable future.
(Ord. 25-21 § 1 (Exh. A))
§ 18.45.170 Fencing.
(2)
Single-Family Residential Land Uses. All properties adjacent to or abutting an existing multifamily or commercial zone shall install fencing compliant with RCC § 18.155.080.

(7)
Open Space. Projects over 10 acres shall include a minimum of one acre of open space. A 10 percent reduction in lot size may be allowed to compensate for this requirement, except where a stormwater management area is utilized as open space. Said open space shall be privately owned and maintained unless otherwise approved by the city council prior to recordation of a plat and/or issuance of any building permits within the project.
