F03 maintenance nutrient removal-broadus
This document outlines a presentation about calculating nutrient removal from maintenance activities to receive TMDL credits. It discusses calculating nutrient removal from street sweeping, catch basin cleanouts, and BMP cleanouts based on weight of collected materials and nutrient concentrations. The results found these activities removed over 1000 lbs each of TP and TN annually from one watershed. Potential improvements discussed separating stockpiles by activity and watershed and establishing activity percentages by watershed.

Editor's Notes
- #3Â What are we trying to find? Nutrient reduction associated with maintenance.What are we already doing? Streetsweeping, bmp & catch basin cleanout. Clean, Stockpile, & Deliver to Transfer StationHow do we capture the data? Process: Invoice Info, Maps, Assign Weights, Calc LoadingWhat did we find? Show Results, Show Map.How can we Improve?
- #10Â GIS Maps to Determine Mi2 swept in each Watershed.Assign % of Total Area and Multiply by Total Collected Weight
- #11Â GIS Maps to Determine Mi2 swept in each Watershed.Assign % of Total Area and Multiply by Total Collected Weight
- #12Â Multiply Nutrient Concentration by Total Collected Weight Per WatershedAccount for Reclaimed Water AreasEX: Hogtown Creek 325.6 mg/kg of TP Concentration * 1,334,764 Pounds Collected in Hogtown Creek Watershed = 434.68 pounds of TP removed from Hogtown Creek Watershed.
- #18 More impaired watersheds are more urbanized so it is likely that these watersheds have higher sediment removal per area swept. Also, Gainesville’s more urbanized watersheds have a higher percentage of BMP’s and catch basins which have the higher nutrient concentration than street sweeping.
- #19 More impaired watersheds are more urbanized so it is likely that these watersheds have higher sediment removal per area swept. Also, Gainesville’s more urbanized watersheds have a higher percentage of BMP’s and catch basins which have the higher nutrient concentration than street sweeping.
- #20Â Once Improvement #1 is implemented and the three maintenance activities have their own pile, GIS can be used to determine the % allocation of BMP and catch basin clean outs to each watershed, just the way it was used to determine % of streetsweeping.
- #21Â Once Improvement #1 is implemented and the three maintenance activities have their own pile, GIS can be used to determine the % allocation of BMP and catch basin clean outs to each watershed, just the way it was used to determine % of streetsweeping.
