The City plans to maintain treatment BMPs within CSLTE1 based on BMP RAM and NPDES inspections. Essential and Key BMPs and will be maintained by the City Street Maintenance crew on an As-Needed basis. Maintenance will be performed by backhoe and/or hand crew (possible CCC work) to remove excess sediment from the basins. Emphasis will be placed on restoring the soil in the basins to an infiltration rate consistent with the BMP RAM benchmark value.

The City plans to inspect all treatment BMPs with CSLTE1 in accordance with the BMP RAM. Additional inspections may be performed if required by NPDES permits, or to assess performance or maintenance needs. 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.
