Specifications include, but are not limited to: Engineering, hydraulic, and other technical analyses including fluvial geomorphological assessments and hydraulic stream channel modeling;2.Watershed hydrologic modeling suitable for watershed-wide accounting of runoff volume and pollutant load reductions (e.g., Opti-Tool) associated with site design and stormwater best management practices;3.Field assessments to include geomorphological, biological, soil, topographic, property or other land surveys, and water quality sampling and flow measurements;4.Site design/landscape architectural and related services to promote environmental sensitive design (ESD) approaches to development, minimize hydraulic connection of impervious cover to surface waters, and support planning and design of low impact development (LID) and green infrastructure (GI) stormwater best management practices;
