APPROVE THE INSTALLATION OF MODULAR SPEED TABLES ON FLAGLER LANE BETWEEN 190TH STREET AND BERYL STREET

Funding for the installation of the speed tables is available in the Traffic Calming Project account.

The City also recorded traffic volumes that are higher than what is typically experienced on other ...
