About this file
This Transportation Technical Manual Bulletin 23-01, issued by Hillsborough County's Engineering & Operations Department in Florida, provides comprehensive guidelines for pavement marking removal methods in construction projects. The bulletin rescinds and replaces previous bulletins from January 2021 and May 2022, establishing new requirements for how contractors must handle pavement marking removal during construction plans, temporary traffic control operations, and in cases of marking errors. Key requirements include prohibiting the use of grinding, water blasting, or other removal methods on final flexible pavement surfaces, mandating that unsuitable permanent markings be removed by milling at least 1.5 inches deep, and requiring contractors to pre-mark and notify the County Engineer one week prior to placing temporary or permanent pavement markings.
The document outlines strict criteria for pavement marking removal, emphasizing safety and visual clarity for drivers. The use of black paint to mask existing markings is explicitly prohibited, and any removal method must completely eliminate conflicting markings without leaving scarring, remnant markings, or discoloration that could confuse drivers under various driving conditions. If ghost markings remain or pavement damage occurs, additional corrective actions like milling and resurfacing may be required. Contractors have the option to submit alternative removal method proposals for review, but these must meet the county's stringent standards of completely removing markings while minimizing pavement damage.

SUBJECT: PAVEMENT MARKING REMOVAL
This bulletin rescinds and replaces Bulletin 21-06 Pavement Markings Removal by Grinding or Water Blasting dated January 11, 2021 and Bulletin 22-01 Pavement Marking Removal dated May 27, 2022. This bulletin announces treatment of pavement marking removal methods for Construction Plans, Temporary Traffic Control Operations and Pavement Marking Errors during Construction and identifies the Hillsborough County Pavement Marking Removal Method Criteria.
REQUIREMENTS
CONSTRUCTION PLANS AND TEMPORARY TRAFFIC CONTROL OPERATIONS
Hillsborough County Construction Plans and Specifications must not specify the use of grinding, water blasting, or other pavement marking removal methods to change or remove permanent pavement markings on final flexible pavement surfaces. When pavement removal is warranted to remove unsuitable, permanent pavement markings, mill a minimum 1.5-inch depth for the entire affected lane width to place a new surface course, and then apply new permanent pavement markings per the plans.
A note has been added to the County Capital Improvement Program (CIP) Project Standard General Notes (Roadway) sheet that instructs the Contractor to: Pre-mark pavement marking placement and notify the County Engineer the time and date of placement of temporary and permanent pavement markings one week prior to installation. County Construction Engineering and Inspection personnel must be on site to inspect pavement marking placement and installation

EXHIBIT 4
in accordance with the County's Contract Documents, Specifications, and Construction Plans.
Grinding, water blasting or other nondestructive methods, as approved by the Engineer, will be allowed for removal of existing pavement markings on existing pavement surfaces during Temporary Traffic Control Operations, only when the construction plans specify the existing pavement is to be replaced with new permanent pavement. Where construction exceeds three working days, safety measures such as retroreflective raised pavement markers (RPM’s) must be used in conjunction with the new temporary striping. This process will only be allowed during Temporary Traffic Control Operations.
A note has been added to the CIP Project Standard General Notes (Roadway) sheet that states:
Pavement markings placed on existing pavement for Temporary Traffic Control, beyond the limits of new permanent construction shown in the plans, must be removed by milling and resurfacing.
Limits of milling and resurfacing will extend to the limits of all temporary pavement markings placed on the existing pavement. Pavement marking plans for temporary traffic control extending beyond the limits of new permanent construction shown in the plans must be approved by the Engineer.
The two general notes above must also be included on all Subdivision and Site Development Project plans.
PAVEMENT MARKING ERRORS DURING CONSTRUCTION
Permanent pavement markings incorrectly constructed by Contractors working within County right-of-way, or on projects where right-of-way will be turned over to the County, must be corrected by Milling, Resurfacing and Restriping at no cost to the County. The Contractor has the option to submit a proposal for an alternative pavement marking removal method, in lieu of the milling and resurfacing method. The proposal must be submitted for review and approval to Construction Services of the Capital Programs Department in accordance with the governing Contract Documents. A form for requesting an alternative pavement marking removal method proposal is provided on Page 4.
PAVEMENT MARKING REMOVAL METHOD CRITERIA
The use of black paint to mask existing pavement markings is prohibited on all Hillsborough County roads. The proposed pavement marking removal methods stipulated above for “Construction Plans and Temporary Traffic Control Operations” and “Pavement Marking Errors During Construction” must achieve complete removal of conflicting existing pavement markings and must not leave scarring, remnant markings or discoloration that may mislead or cause confusion for drivers in wet, dry, daytime, nighttime, or any other adverse driving conditions. If the removal method results in ghost markings that may create a safety concern or damages the pavement, then additional corrective action may need to be taken that may require milling and resurfacing.
BACKGROUND
Pavement marking removal can be problematic if the markings are not completely removed or the removal technique produces scarring of the roadway surface, which can be confusing to drivers, create an unsafe driving environment, and negatively impact the pavement condition. The result
HCFLGOV.NET Page 2 of 4 can include scarring that leaves the pavement with imprints of the removed markings which are especially noticeable in rainy conditions. These ghost markings create confusing information to drivers. These methods of pavement marking removal may also damage the surface course leading to reduced service life.
IMPLEMENTATION
Implementation is the date of the County Engineer’s signature.
