orchards drainage study
Gonzalez was hired to perform a drainage study for the purpose of delivering a comprehensive plan providing recommendations to reduce flooding potential throughout the development.
The drainage study included an inventory of flood prone areas and identification of potential causes of flooding. Gonzalez performed GPS data
collection of critical infrastructure at approximately 80 locations in the development.
Hydrologic and hydraulic analyses were performed to calibrate known flooding to historical storm events, estimate flood potential, and develop recommendations to reduce flood potential throughout the development. Conceptual drawings, an opinion of probable cost, and a priority ranking were developed for each of the recommended improvements to allow the City of Belleville to plan for the implementation of drainage improvement projects for the benefit of impacted residents.
