Inspections will take place beginning in spring and will continue through the fall. Essential and Key BMPs will be inspected according to the BMP RAM and NPDES permit. Engineering staff will use the Constant Head Permeameter (CHP) to determine the infiltration rate of the basin. Staff Gauges will also be utilized to determine the amount of sediment in the Basins. Staff will also perform a visual inspection and record results with a handheld GPS unit or field tablet. Inspections of all Basins will take place in the late spring or early summer. Trash assessment will also be completed in accordance with the State Trash Policy and City's 2018 Trash Implementation Plan.
