3. Major Street Map

a. Adoption by the Governing Body

To establish building or setback lines on existing and proposed major streets within the City and prohibiting any new building being located within the building or setback lines, the Governing Body, pursuant to the authority of K.S.A. 12-765, adopted an ordinance establishing building or setback lines on existing and proposed major streets, prohibiting any new building being located within the building or setback lines. This ordinance incorporates by reference the Major Street Map, with its supplementary documents, which sets forth the major street plan for the City and shows, to the extent possible, the location and width of existing or proposed major streets or highways and right-of-way widths. At least three (3) copies of the Major Street Map together with the adopting ordinance are on file and available for inspection in the offices of the City Engineer and the City Clerk.

b. Filing with Records and Tax Administration

A certified copy of the Major Street Map and adopting ordinance shall be filed with the Records and Tax Administration of Johnson County, Kansas.

c. Measurement of Yard and Lot Areas

In measuring any required yard or lot area, those portions of a lot which lie in an established or proposed street right-of-way as defined on the Major Street Map and supplementary documents are not counted as part of any of the required yard or lot area.

d. Adoption of Building and Setback Lines

The building and setback lines for existing and proposed major streets and highways shall be those building and setback lines established by the applicable provisions of the Unified Development Ordinance (UDO) and Olathe Municipal Code.

e. Access Management Plan

All access from driveways, private streets and public streets onto adjacent properties shall conform to and be subject to the Access Management Plan.

f. Amendment

The Major Street Map may be amended by ordinance in accordance with K.S.A. 12-765. The Access Management Plan may be amended by resolution by the Planning Commission and the Governing Body.

B. Street Layout

1. Generally

a. Proposed new streets shall be designed and located in relation to existing and planned streets, topographical conditions and natural terrain features such as streams and existing tree growth, to promote public convenience and safety, and in appropriate relation to the proposed uses of land to be served by the streets.

b. All streets shall be properly integrated with the existing and proposed system of collector and arterial streets, and dedicated rights-of-way, as established on the Major Street Map, Transportation Plan, and Access Management Plan and this ordinance, or as directed by the City Engineer.

c. All service, collector and arterial streets shall be properly related to special traffic generators such as industries, business districts, schools, churches and shopping centers, population densities, and the pattern of existing and proposed land uses.

d. In business and industrial developments, the streets and other access ways shall be planned in connection with the grouping of buildings, location of rail facilities, truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of movement between the various types of traffic, including pedestrian.

e. All streets within subdivisions shall conform to the Technical Specifications and Design Criteria for Public Improvement Projects.

f. A fire apparatus access road shall reach one hundred fifty (150) feet of any portion of an exterior building, as required by the Fire Code and subsection C, below.

g. The final street design and arrangement of the development shall be completed in accordance with the Major Street Map, Transportation Plan, Access Management Plan, Technical Specifications and Design Criteria for Public Improvement Projects and applicable corridor studies and plans.

h. All streets whether platted as public or private shall be built to City standards.

i. All setbacks are measured from the edge of pavement.

2. Connectivity

Street layouts should respond to local conditions such as topography, watercourses, greenways and the existing street systems of neighboring developments. Local street patterns may discourage through traffic, but should also include interconnecting streets with alternative routes throughout the neighborhood to diffuse automobile traffic and shorten walking distances. A well connected street network shall be provided to spread traffic efficiently, and to provide greater opportunities for access and circulation of motor vehicle, pedestrian, and bicycle modes of travel.

a. External Connectivity

(1) Where adjoining areas are not subdivided, the arrangement of streets in the subdivision shall provide for the extension of streets into the unsubdivided areas.

(2) Parcels shall be arranged to allow the opening of future streets and logical further subdivision.

(3) Proposed streets shall be extended to the boundary lines of the tract to be subdivided or developed, unless prevented by topography or other physical conditions, or unless the Planning Official determines that the extension is not necessary or desirable for the coordination of the layout of the subdivision or development with the existing layout or the most advantageous future development of adjacent tracts.

(4) At least one (1) street shall extend to the boundary line of the tract for each six hundred sixty (660) linear feet of the boundary line with adjoining tracts. This section does not require designated local streets to extend into floodplains, bluffs or other natural features or existing development that does not accommodate the connection.

b. Internal Connectivity

(1) The following terms are defined for purposes of this subsection only:

Street Link

That portion of a Street that lies between 2 nodes.


The intersection of two (2) or more streets, a cul-de-sac head or a dead-end. The following are not considered Nodes:

• An eyebrow. An eyebrow is a semicircular shaped portion of a street that is configured so that a circle with a radius of thirty (30) feet can fit within the confines of the paved portion of the surface.

• The intersection of a local street within the proposed subdivision with an external public street that connects to the proposed subdivision is not considered a node in computing the connectivity ratio.

Pedestrian Connection

A pedestrian accessway or portion of a development’s trail system that:

• Complies with Section 18.30.180.B and C, and

• Connects a dead-end street, cul-de-sac, or T-intersection to another public street or to a commercial or office development that is built, approved, or designated as part of the proposed development. Pedestrian accessways or trails that connect only to parks, greenways or recreational areas are not counted as a pedestrian connection for purposes of calculating the connectivity ratio.


See Section 18.90.020.

(2) Streets within any proposed residential subdivision shall provide a connectivity ratio as provided below. The connectivity ratio is computed by dividing the number of street links and pedestrian connections by the number of nodes within the subdivision.

(3) The Planning Commission may modify the connectivity ratio (see Section 18.30.020.B) by counting a feature as a street link or pedestrian connection or reducing the required ratio if:

(a) Existing topography or natural features make the required number of connections impractical, and

(b) The applicant provides alternative solutions that substantially accomplish the purposes of this section.
