17.04.073 Streets.
A. The on-site street system shall be coordinated with existing, proposed, and anticipated streets beyond the land that is being divided into lots. The arrangement of streets shall provide for the continuation of principal streets and adjacent properties for the convenient movement of traffic, effective fire protection, efficient provision of utilities and conformance with the Comprehensive Plan.
B. Whenever access to adjacent un-subdivided property or connections to anticipated or proposed surrounding streets are required, the street right-of-way shall be extended and the street developed to the property line of the subdivided property, or to the edge of the undeveloped portion of a single tract, at the point where the connection to the anticipated or proposed street is expected. In addition, the City may require temporary turnarounds to be constructed at the end of such streets pending their extension when such turnarounds appear necessary to facilitate the flow of traffic or accommodate emergency vehicles.
The City may waive these requirements if one of the following criteria is met:
1. Topography or other physical condition makes it impracticable to provide access to adjacent un-subdivided property.
2. Adequate public access is otherwise available to the adjacent unsubdivided property.
3. The adjoining un-subdivided property is under a conservation easement or other legally restrictive covenants. (Ord. 1687, 2009).
C. Streets shall be related appropriately to the topography. In particular, streets shall be designed to facilitate the drainage and storm water runoff and to conform as closely as practicable to the original topography.
D. Streets shall be laid out so as to intersect as nearly as possible at right angles. Clear visibility shall be provided for a minimum distance of ten (10) feet at intersections, as measured along the property line of the streets, or as approved by the City Engineer based on street alignment and gradients. (Ord. 1687, 2009).
E. The following design standards shall apply for dedicated rights-of-way:
Local or Residential | Collector | Arterial | |
|---|---|---|---|
Required Right-of-Way | 60 feet | 60 feet | 80 – 100 feet |
Required Pavement Width | 20 feet (28 with parking) | 24 feet (36 with parking) | 60 feet |
Design Speed | 25 miles per hour | 35 miles per hour | 35 miles per hour |
Maximum Length of Cul-de-Sacs | 180 feet | Not allowed | Not allowed |
Minimum Radius of Turn- Around for Cul-de-Sacs | 75 feet | Not allowed | Not allowed |
F. After sewer and water utilities have been installed, the subdivider shall construct streets to the widths prescribed above with the construction materials and methods in conformance with “Standards and Specifications for Municipal Public Works Construction” prepared by the American Public Works Association for Class B plant mix asphalt or better.
G. Streets not dedicated to the public must be clearly marked on the face of the plat.
H. Shared Driveways. No more than two parcels may be served by a shared private driveway which shall comply with the following standards:
1. A shared driveway shall be owned and maintained by the owner(s) of the parcels or lots sharing access on the driveway;
2. No more than two single family or multi-family units may access a shared driveway;
3. A shared driveway shall be at least 12 feet (12') wide and not longer than one hundred and fifty feet (150');
4. No parking is allowed on the shared driveway; and
5. Each lot sharing access on the driveway must provide on-site parking spaces as per KFMC 17.03.014. (Ord. 1687, 2009).
I. Fire equipment access must be provided for every building located more than one hundred fifty feet (150') from an approved public way. Fire equipment access may be provided by a driveway providing vehicular access to structures on no more than two parcels. (Ord. 1687, 2009).
J. Second or Emergency Access: To facilitate traffic, the provision of emergency services, and the placement of utility easements, the subdivider shall provide all subdivisions of 20 lots or more with a second means of access consisting of a dedicated public right-of-way developed to the standards in this Section and connecting to a public road at a minimum of three hundred feet (300') from any other intersection of a public road. If, in the judgment of the Council, a second dedicated right-of-way cannot be provided for reasons of topography or other physical conditions, the subdivider shall provide an emergency access with the following standards:
1. Minimum easement width forty feet (40');
2. Minimum twenty foot (20') unobstructed travel way with all-weather surface. All-weather surface is defined as a paved road surface which emergency and passenger vehicles can pass at all times;
3. Connection to a public road at a minimum of three hundred feet (300') from any other intersection of a public road;
4. Signage clearly visible and legible identifying the emergency access;
5. Obstructing an emergency access road is prohibited. Signage may be required stipulating this provision; and
6. A recorded road maintenance agreement is required. It must be demonstrated that upkeep is provided for the entire length of the road being used as emergency access to improved properties. The agreement must state that the City is not responsible for constructing, improving, maintaining, repairing, providing drainage or snow removal on the private road providing emergency access. (Ord. 1687, 2009).
K. All streets, lanes, driveways, and emergency access roads shall have unobstructed vertical clearance from trees, power lines and other utilities, entry gates, etc. of not less than thirteen feet six inches (13' 6"). (Ord. 1687, 2009).
L. Private lanes shall not be permitted inside city limits. Existing private lanes: Boise-Sanders Lane, Honey Bee Lane, Morley Lane, and Walker Way shall be grandfathered. Any further land divisions or annexations affecting Boise-Sanders Lane, Honey Bee Lane, Morley Lane, or Walker Way will require that these lanes be improved or other streets be established to meet the standards of this Section. (Ord. 1687, 2009).
M. Half streets shall be prohibited except where essential to the reasonable development of the subdivision in conformity with the other requirements of this Section and where the City finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided. Whenever a half street is adjacent to a tract being subdivided, the other half of the street shall be included as a part of the subdivision. (Ord. 1687, 2009).
