12 - Short-Term Traffic Control Plan (TCP) Review Guidelines

The Los Angeles Department of Transportation (LADOT), as part of a streamlining process developed LADOT Standard Plan S-488.1 for Short Term Traffic Control Plans (Less than 72 hours). Additionally, as part of this process, LADOT created a new TCP Flow Chart depicting the required TCP based upon the Mobility 2035 Street classification, proximity to intersections and number of lanes to be closed.  

Below are the types of TCP options, who is responsible for reviewing the plans, and for the Short Term Traffic Control Plans, BOE's procedures for reviewing the TCP.

1. LADOT Review 
   1. Professionally Prepared Work Site Traffic Control Plans (Non-Engineer designed) 
   2. Engineer Designed Work Site Traffic Control Plan (Engineer of Record Required)
2. BOE Review
   1. Short Term Traffic Control Plans (permit related only) based upon LADOT Standard Plan S-488.1 shall be submitted to BOE’s District Office for review 
      1. TCP must be signed by the Applicant
      2. Multiple standard plans submitted shall be submitted if there are multiple excavations with differing lane closure configurations.  BOE staff will review plans using the LADOT TCP Flow Chart for the following conditions:
         1. Verify the lane closure does not fall within the limits of the TCTMC Streets of Significances (can be found in NavigateLA).  If the lane closure is subject to TCTMC review, the applicant should submit the TCP to Eng.TCTMC@lacity.org for review and approval. 
         2. Bike or vehicle lane closures not on a designated Boulevard or Avenue:

            1. If a worksite closes the shoulder/sidewalk or is on a designated Local or Collector Street, the applicant should use the WATCH Manual or CA MUTCD. 

         3. Bike or vehicle lane closures on a designed Boulevard or Avenue:

            1. Verify the selected standard plan under Standard Plans S-488.1 match the exact road configuration and work zone. It must include the followings items, but not limited to:

               • Work Zone, Number of Travel Lanes, Lane Reductions, Two-way Left Turn Lanes, Median Islands, Curb Islands, Bike Lanes, Edge Lines, Left-Turn Channelization, Right-Turn Channelization, Signalization, etc. 

      3. TCP must match road conditions and work zones depicted in the relevant standard plan. The road closures generally occur between 9:00 AM to 3:30 PM using daily portable traffic safety devices. 
      4. Using the LADOT TCP Flow Chart, BOE staff shall review TCP submittals
      5. BOE staff shall consult with their supervisor when making a final determination on whether LADOT needs to review/check the TCP.   LADOT may require the Applicant prepare a professional Work Site Traffic Control Plans (Non-Engineer Design) or engineer designed Work Site Traffic Control Plan (Engineer of Record Required). The following are typical scenarios where LADOT would handle the review: 
         1. Up to Three Lanes in each Direction without Bike Lane
         2. Up to Three lanes in each Direction with Bike Lane
         3. Curb and Gutter Replacement
         4. Corner Ramp Replacement
         5. Complex construction sequence 
         6. BOE opts to return the TCP to LADOT 
      6. BOE staff shall also check for the following items:
         1. Proposed work area shown on the design plan matches the location of work area shown on the TCP
         2. Street designations of the Primary and Secondary Street (if applicable)  are correct and match in NavigateLA
         3. The speed limit for the Primary and Secondary Street are shown (BOE does not verify accuracy)
