Recommended Green Infrastructure Practices Qualified consultants will be expected to prepare a feasibility study to determine drainage improvements that will use green infrastructure (rain gardens, native plantings, lawn replacement etc.) to stem flooding, maximize infiltration and mitigate impacts of stormwater runoff to surrounding waterbodies in the Crab Meadow Watershed. Estimation of water quality volume to be managed Qualified consultants will be expected to estimate the water quality volume to be treated by proposed improvements. Estimates should be broken down into subcategories which include the estimated quantities of Total Suspended Solids (TSS), Total Phosphorous (TP), Total Nitrogen (TN), Fecal Coliform absorbed by each improvement and Runoff Reduction Volume provided by each improvement. Ranking of Green Infrastructure Improvements Qualified consultants will be expected to supply a ranked improvement location list based on data collected. Project Cost Estimate Qualified consultants will be expected to provide cost estimates for each of the green infrastructure projects. Maintenance Policy and Procedures Qualified consultants will be expected to create a maintenance plan to ensure success and viability of proposed green infrastructure improvements.
