Watearth is leading the Mills Tower Drainage Feasibility Study for the City of Rancho Cordova The study addresses persistent flooding across a 152-acre drainage area with constrained pump station capacity.
Over the course of the project, Watearth has reviewed the City’s Master Plan, FEMA documentation, topographic and soils data, and hydrologic and hydraulic models. Initial site visits and a kickoff meeting helped validate desktop findings and identify opportunities for flood mitigation, including detention basins at White Rock Elementary School and Community Park, as well as distributed low impact development (LID) features.
Simulations for 10-year and 100-year storm events informed the performance evaluation of alternatives. The team has produced 10% concept layouts that integrate flood control, water quality, and recreational benefits, along with preliminary cost estimates and a comparative cost-benefit analysis. Deliverables include a detailed technical memorandum and ongoing virtual coordination with City staff.
