2019 – Basin 33 & 34 Drainage Masterplans

The city wanted to update old drainage masterplans for improved accuracy and completeness utilizing the system MRPE developed for Basin 129.

MRPE surveyed and performed hydraulic and hydrologic modeling, prepared, and mapped flooding. MRPE surveyed and created a complete model for Basin 34, as well as a floodplain analysis for future FIRM mapping. Basin 33 model was converted from SSWMM to XPSWMM with an updated datum. All deficiencies within both basins were identified.

Our surveying and data analysis methods were refined as we created another complete model with all conduits and field-surveyed roads. A uniquely accurate two-way dynamic stage flow hydrograph method was derived to account for back-and-forth overland releases between neighboring basins.
