Traffic Sign Installation

Sign Inventory


The City of Blaine will develop and maintain a sign inventory of all signs on the roadway system. Based on the inventory and level of funding available for sign maintenance, the City will determine the amount of inventory that can be supported by the current funding structure.

The City of Blaine will maintain the determined amount of traffic control devices (signs, traffic signals, and pavement markings) to ensure safe and efficient operations. Based on the inventory and policy considerations, signs that are not consistent with policy, and signs that are not required or are determined by an engineering study to be unnecessary, will be removed.


Traffic Sign Best Practices


The following best practices will be implemented to assist in determining the need for all traffic signs:
  • The application of warning signs will be based on system considerations; locations with similar characteristics will be proactively signed.
  • No stop signs on low volume intersections (fewer than 200 vehicles per day).
  • No warning (curve, pedestrian crossing, deer signs) or regulatory (speed limit, STOP) signs on roads classified as local or residential.
  • Signs that are required will be installed. Signs that require engineering judgment will undergo an engineering study, the results of which will be on file documenting reason for installation.
  • Traffic signs will not be used as a reactive response to traffic crashes.
Application of curve warning signs will be consistent with MN MUTCD requirements along roadways with ADT volumes greater than 1,000 vehicles per day with the following guidelines for ADT volumes less than 1,000 vehicles per day:
Radius Horizontal Curve Signing
Greater than 2,000 feet
No sign
1,500 to 2,000 feet
Curve Ahead warning sign
1,200 to 1,500 feet
Curve Ahead warning sign and Speed Advisory plaque
500 to 1,200 feet
Curve Ahead warning sign, Speed Advisory plaque and chevrons
