Division One - Standards for Streets - Chapter V. Access

Chapter V. Access

Sec. 105-1 State Highways

Access to state highways, is regulated by Caltrans. Requests for access and changes to existing access shall be coordinated with Caltrans. Encroachment permits for access to state highways shall be obtained from Caltrans.

Sec. 105-2 City Streets

Access to city streets, is regulated by the incorporated city who has jurisdiction. Requests for access and changes to existing access shall be coordinated with the respective incorporated city. Encroachment permits for access to city streets must be obtained from the respective incorporated city.

Sec. 105-3 County Roads – Access Limitations and Intersection Locations

Arterial streets are designed primarily for the movement of through traffic (80% to 90%) with minor usage as access to abutting properties (10% to 20%). Collector streets operate at approximately 40% to 60% either way. Local street’s function is to provide nearly 100% access to abutting properties and should be designed to eliminate through traffic.

Driveway access on arterials shall be kept to a minimum as determined by safety, topography, zoning and prior parcelization constraints or other special circumstances. Waivers of access on subdivisions shall be provided along major streets except where driveway access is permitted.

105-3.01 Minimum full access intersection spacing on arterials shall be limited to one-third mile. Closer spacing may be permitted if a traffic signal synchronization study is approved which demonstrates the location to be feasible for a signal. The signal, if allowed, shall be funded and installed by the developer.

105-3.02 Minimum spacing and type of local street access along arterial and collector streets shall conform to details in Plates R-49 and R-50. Access points along arterial streets shall be restricted to right turn in and right turn out movements only. Full access median openings or openings limited to allow left turn in with no left turn out may be permitted where an approved traffic study provides justification for said access. Analysis for and development of full access openings must also meet the signalization requirements of Section 105-3.03. The design of limited access openings shall conform to applicable details in Plates R-42 through R-50.

105-3.03 For purposed development of no more than 200 residential dwelling units, circulation may be developed with only one access available. Development beyond 200 units will be required to provide a second means of access. Access points on collectors within 300 feet of the curb return at an
arterial intersection shall be limited to right turn in and right turn out movements. This provision in no way limits more restrictive secondary access  requirements, imposed for public safety purposes.

Sec. 105-4 County Roads – Driveway Approaches

All construction to connect driveway approaches to county roads must first be authorized by a valid Encroachment Permit. The design, number and location of driveway approaches must comply with the standards and policies contained herein and must be approved by the County.

105-4.01 Driveway approaches will not be permitted for parking or loading areas which would require backing into county roads with the exception of single family (R-1) residences.

105-4.02 Driveway approaches constructed along arterial streets shall be restricted to right turn in and right turn out movements only. Full access median openings or openings limited to allowing left turn in
with no left turn out may be permitted where an approved traffic study 18 provides justification for said access. Analysis for and development of  full access openings must also meet the signalization requirements of  Section 105-3.03. The design of limited access openings shall conform to applicable details in Plates R-42 through R-50. Driveway approaches constructed along collector streets within 300
feet of the curb return at an arterial intersection shall be limited to right  turn in and right turn out movements.

105-4.03 Only one driveway approach per property per street is permitted for single family R-1 lots excepted on local streets. Additional driveway approaches may be permitted where an approved traffic study is provided which demonstrates that more than one access is required to adequately handle driveway volumes, and will not adversely affect traffic flow on county roads.

    1. Where a property has access to more than one street, at a double frontage location, access will be limited to the lower classification street to minimize the impact upon traffic flow, except as allowed herein. Access to only the higher classification street will be required in the case of incompatible land uses, i.e., the lower classification street serves residential development and the access is to serve commercial or industrial development.

Addition of access to the higher classification street may be allowed provided an approved traffic study provides sufficient justification. Access to the higher classification street may be denied and may also
be subject to other constraints contained in these standards and by County regulations. 

105-4.04 After all improvements have been accepted by the Roads/Engineering, Surveying & Permit Services Departments, the reconstruction, repairs, and maintenance of all driveways, driveway approaches and sidewalk will be the responsibility of the property owner. During construction all such activities will be the responsibility of the permittee.

105-4.05 Arrangements must be made by the developer or permittee, for the necessary removal or relocation of any public utilities, structures, trees or plants with the person or entity having ownership or control prior to commencing work. Removal or relocations must be accomplished at no cost to the County.

105-4.06 Driveway profiles shall comply with the Kern County Type A Street Improvement Details, Plates R-53 thru R-55.

Sec. 105-5 County Roads – Turn Lanes

105-5.01 Arterial Streets: Left turn storage lanes are required to all streets and 19 access points where left turn ingress is permitted along arterial streets. Right turn storage lanes are required at all streets and access points where one of the following criteria is met:

  1. The 85th percentile speed is less than 45 MPH and the peak hour turning volume is over 200.
  2. The 85th percentile speed is 45 MPH or greater, the arterial is shown ultimately having 6 lanes and the peak hour turning volume is 25.

105-5.02 Collector Streets: Left and right turn storage lanes are required on all collector streets at arterial street intersections. Striping for left turn channelization shall be provided for any access leading to a development, which, at build out, generates more than 50 peak trips.

105-5.03 Design of left and right turn storage lanes shall comply with the applicable requirements of details in these standards. Bay tapers for turn lanes shall be 90 feet in length for single turn lanes and 120 feet in length for dual turn lanes. 60' bay tapers will be permitted on streets where the 85th percentile speed is 40 MPH or less, provided the turn lane is accessing either a driveway or a local street.

105-5.04 In the absence of turning volume data showing the need for greater storage, the following minimum lengths shall be used:

Dual left and single right turn storage lanes from arterial street into another arterial street shall be designed for a minimum length of 200 feet (measured from end of taper to limit line). Left and right turn
storage into local streets or major private entrances shall be 150 feet minimum. Left and right turn storage into minor private entrances shall be 100 feet minimum on collector streets and 150 feet minimum on arterial streets.

105-5.05 Upon subdivision or other development which accesses onto an arterial or collector street, the following minimum improvements will be required to provide left turn channelization, where insufficient width would otherwise be available due to existing or proposed street improvements.

On and off site road improvements are required from any collector or arterial street to provide left turn channelization into each street (or access point) within the subdivision (or development). Said channelization shall be developed to provide necessary transitions and turn lanes to meet the current Caltrans standards for the design speed of the roadway in question.

Sec. 105-6 Bus Turnout

Bus turnouts and associated speed change lanes will be required on future and existing bus routes at locations identified by Golden Empire Transit (GET)/Kern Regional Transit 20 (KRT). Design shall be based upon standards contained in Plates R-66.
