DKS Associates 7. Guidelines for Design Standards ' Guidelines for design standards for the spacing of driveway access locations and street intersections along Bristol Street have been established. These guidelines are discussed below in detail. The goal of the Bristol Street widening and Specific Plan project is to improve efficiency and safety along this major arterial. Currently, vehicular congestion exists along Bristol Street as a result of cross traffic between intersections and uncontrolled driveway access points. The impacts of driveways on arterial street capacity and safety make it apparent that it is in the Santa Ana community's best interest to: f) limit the number of driveways to those which are actually needed to safely accommodate the traffic generated by the Specific Plan project, 2) provide adequate spacing between driveways so conflicts (and resulting accidents) between vehicles maneuvering at adjacent driveways do not arise, and 3) ensure proper design to accommodate driveway traffic and minimize vehicle conflicts without significantly reducing roadway capacity. The guidelines and proposed standards outlined below have been developed to identify acceptable access spacing and location for the Bristol Street Specific Plan project. Multiple Driveways By law, each parcel of land must be granted access (restricted or full) to a public roadway, except under certain special conditions. Consolidation of parcels and shared - driveway policy may be implemented to satisfy this requirement while reducing the number of driveways. Spacing or Signalized Intersections If a proposed driveway warrants a signal, its location may need to be reassessed based on minimum acceptable spacing for a progressive signal coordination along Bristol Street. Spacing Between Driveways The spacing between two driveways and intersections in the guidelines refers to the distance between the inner curbs of those two driveways or intersections. 28657.P902ZW..Rpt 35
