22-027 - 12th Avenue At Fairfield Drive Drainage Improvements

The intersection of 12th Avenue and Fairfield Drive has experienced issues with stormwater stacking in the road and creating a hazardous driving condition. This is due to the existing stormwater conveyance system being undersized for its contributing basin’s flow. This project will serve to increase the hydraulic capacity of the conveyance system by enlarging the curb inlet top and installing a new stormwater conveyance route into the existing/downstream conveyance system. As a result of these improvements, work site safety, MOT, maintenance/bypass of stormwater flow, and erosion control will be paramount issues. General work to be accomplished will include enlargement of the curb inlet top, cut and patch of pavement, storm structures, new storm pipe, and sod.
