Striping plans identify all other traffic control devices.  \nStriping plans generally shall be prepared by the Geometric Design staff for projects involving City streets. Exceptions are as follows:  \n􀁸 Plans prepared by consultants for private entities as part of the B-Permit process;  \n􀁸 Plans prepared by consultants pursuant to an agreement with a governmental agency;  \n􀁸 Plans prepared by employees of another governmental agency; and  \n􀁸 Projects for which the Bureau Head or higher authority has approved plan preparation by a non-governmental entity.  \nPlan Approval  \nAll striping design plans prepared for locations under the jurisdiction of the City of Los Angeles shall be signed as follows:  \n􀁸 By the Section Head of the Geometric Design Section unless that person is absent;  \n􀁸 By the Division Head of the Design Division unless that person is absent; and  \n􀁸 By the Bureau Head responsible for the Design Division, unless that person has delegated approval authority to the Division Head.  \nStriping design plans submitted by another governmental agency for locations partially under the jurisdiction of the City of Los Angeles shall require the signature of the Bureau Head responsible for the Design Division, or the Division Head if approval authority has been so delegated.  \nThe practice of traffic engineering requires that striping design plans be signed and stamped by Civil Engineers registered in the State of California. Accordingly, the final approval authority for plans prepared by the Department shall be so registered and shall sign and stamp said plans. Consultants or other persons preparing or submitting striping design plans to the Department shall be so registered and shall sign and stamp said plans.  \nConsultants submitting plans shall meet two other requirements. First, they must have a Business License in the City of Los Angeles. Second, they must indicate on the plan that the plan has been reviewed by a person who is either registered as a Traffic Engineer in the State of California or who has a Professional Traffic Operations Engineer Certificate issued by the Institute of Transportation Engineers.  \nStriping Plan Implementation  \nApproved striping plans are to be implemented as shown in the table below:  \nInitiation of Project Department-Initiated Street Resurfacing  \nB-Permits (Developers) City Contracts & CIP Non-City Public Agency  \nInstallation By  \nLADOT Field Forces  \nLADOT Field Forces B-Permit Contractor City Contractor  \nTheir Contractor or by LADOT Field Forces , per an approved agreement  \nFor work otherwise performed by LADOT field forces, elements, such as sandblasting pavement message installation, etc. may be contracted out at LADOT's discretion. For work by contractorson City Streets, LADOT and the Bureau of Contract Administration must inspect and approve the striping.  \nIn all cases, the final thermoplastic striping may not be installed until LADOT confirms that the markout is consistent with the signed plan.  \nPlan Format  \nAll plans of the Geometric Design Section shall be prepared in the latest version of AutoCAD, as menu-enhanced for use by LADOT, except for those plans exempted by the Bureau Head for emergency purposes. Right-of-way, roadway and lane widths shall be shown at separate crosssections wherever the dimensions change. All right-of-way and roadway curve radii shall be dimensioned. All striping tapers, tangents, and curve radii (if not parallel to curb) shall be dimensioned.
