A. Task 1: Data Compilation VRWJPO staff will work with all MS4s to administer a pre-study inventory (see Appendix F) of past and present annual sweeping activities for inclusion in study analyses. The selected consultant will acquire and compile all additional data needed, including, but not limited to: GIS data (number of lane-miles, tree canopy cover, sweeping frequencies and zones, municipal stormwater infrastructure); relevant monitoring and modeling results; and numerical Waste Load Allocation data. One kick-off meeting will be included within Task 1 for the selected contractor, VRWJPO and DC staff to use for project planning. Deliverables: The selected consultant will provide VRWJPO and DC staff agenda and meeting notes for the project kick-off meeting. VRWJPO will provide selected consultant results of pre-study inventory of activities. Consultant will obtain relevant MS4 GIS data and provide VRWJPO staff a list of data obtained. B. Task 2: Evaluation of Existing Watershed Conditions The selected consultant will develop a methodology to evaluate existing watershed conditions absent of MS4 sweeping program. Variations between pollutant recovery, pollutant reduction and pollutant loading will be detailed. Items assessed will include, but not be limited to: imperviousness; canopy cover; road surfaces; and P8 and/or WQM pollutant models for TP and TSS. Deliverables: Maps and narratives of areal TP loading throughout VRWJPO at the catchment-scale; and maps and narrative of areal TSS loading throughout VRWJPO at the catchment-scale...
