Specifications include, but are not limited to: a. Reaffirm the benefits of the WSNSP through design level system modeling. b. Perform an engineering and cost/benefit review of the Phase 1 storage sites to determine which location (Centennial Park or Community Playfield) is most feasible and desirable. Document results in a memorandum to be reviewed at a meeting of the Village Board. c. Coordinate with the Village’s GIS Consortium representative to obtain all available aerial mapping and utility data for the WSNSP sites and the surrounding areas. Note this data is intended to supplement, not replace a detailed field topographic survey. d. Conduct a detailed topographical survey (including above and underground utilities, structures, ground contours, critical ground spot elevations and trees) necessary to support constructible plan sets for all three phases of work.
