Project Deliverables

This project will be completed in four distinct phases. In each phase a draft report is presented, the project sponsors review it, and then the final report is published. Each phase has a unique "stand alone" document that is available to the public.

Hydrology Report

The hydrology report serves to quantify the peak stormwater flows associated with the different return frequency storm events. This hydrology takes into account the existing and future land use conditions and is used as the baseline hydrology for the Flood Hazard Area Delineation, the Alternatives Evaluation Report, and the Conceptual Preliminary Design Report.

Flood Hazard Area Delineation

The Flood Hazard Area Delineation Report (FHAD) delineates the limits of the floodplain during a 100-year storm event. This report will be used to update the floodplain delineation along the Grange Hall Creek and its tributaries. This report will depict the existing flooding problems along the creek without future improvements.

Alternatives Evaluation Report

The Alternatives Evaluation phase of the project investigates improvement scenarios to assure that the most appropriate design recommendations are made. These improvements include channel and roadway improvements, channel stability measures, water quality recommendations, and overall floodplain management practices.

Conceptual Design Report

Once the Project Sponsors have selected the most desirable alternatives from the Alternatives Evaluation Report, this phase of the project further develops the plan into a preliminary design. The purpose of the preliminary design is to better define the critical design elements and to refine future expected construction costs.
