DESCRIPTION
On February 15, 2022, the Board approved CSA No. 17-059-04 with the Consultant to provide professional engineering services for the design of the CR 542A (Galloway Road N) at 10th Street West Intersection Project at a cost not-to-exceed $253,246.38.

Also, when the Level 1 screening was performed the abandoned gas station on the southeast corner was given a risk ranking of 'High'. Level 2 testing, which tests for soil and groundwater contamination, is needed to determine if there are any leaking underground storage tanks.
