About this file
This is a Design Bulletin (23-01) issued by Hillsborough County Engineering and Operations in Florida, effective December 15, 2022, establishing standardized pavement marking removal methods for county construction projects. The bulletin rescinds previous pavement marking removal guidance and applies to construction plans, temporary traffic control operations, and pavement marking errors during construction. For final flexible pavement surfaces, contractors are prohibited from using grinding or water blasting to remove permanent pavement markings; instead, a minimum 1.5-inch depth mill must be performed for the entire affected lane width to place new surface course and permanent pavement markings. County Construction Engineering and Inspection personnel must be on-site to inspect pavement marking placement one week after contractors pre-mark locations and notify the County Engineer of installation dates. For temporary traffic control operations on existing pavement scheduled to be replaced, contractors may use grinding or water blasting only when construction exceeds three working days and retroreflective raised pavement markers are installed with temporary striping. Contractors must correct permanent pavement markings incorrectly installed at no cost to the County through milling, resurfacing, and restriping, though alternative removal methods may be proposed for approval by the County's Construction Services division.
All pavement marking removal methods must completely eliminate conflicting existing markings without leaving scarring, remnant markings, or discoloration that could confuse drivers under any weather or lighting conditions. The use of black paint to mask existing pavement markings is prohibited on all Hillsborough County roads. If removal methods result in ghost markings creating safety concerns or pavement damage, additional corrective action including milling and resurfacing may be required. Contractors proposing alternative removal methods must submit detailed proposals including plans showing errant markings, photographs, equipment specifications, operating parameters, and explanations of how complete marking removal will be achieved while minimizing pavement damage. This bulletin applies to all County Capital Improvement Program projects and Subdivision and Site Development projects within Hillsborough County.

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
HCFLGOV.NET Page 1 of 4 https://HCFLGOV.NET https://HCFLGOV.NET 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 https://HCFLGOV.NET 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.
