Duties included coordination of data collection, supporting design calculation, development of construction specifications and design drawings in CAD, and estimation of construction costs and pollutant discharge reduction.
Bridge & Culvert Design
Fairfield Properties – The Exchange at Charlotte 100+1 Flood Study and Culvert Design: Project Engineer for risk analysis of flood damage at residential multi-family development in Charlotte, NC. Developed a hydrologic model using HEC-HMS to develop flow rates for the 100-year event. Constructed a hydraulic model using HEC-RAS in order to quantify flood elevation. Mapped areas of inundation from an event 1 foot above the 100-year flood elevation using survey and GIS. Designed roadway culvert crossing according to inundation, HW/D, and erosion control requirements.
Waterstone – Cates Creek Crossing Conditional Letter of Map Revision (CLOMR) and Culvert Design: Project Engineer for assessment of proposed mixed development on Cates Creek 100-year FEMA floodplain in Hillsborough, NC. Included development consisted of one ConSpan arch roadway culvert crossing and associated fill. Also included for assessment was an upstream roadway crossing that was incorrectly identified in the effective FEMA study. Modified the effective FEMA HEC-RAS hydraulic model to include proposed and incorrectly identified development and to quantify changes in flood elevation and extent. Designed roadway culvert crossing according to inundation and HW/D. Revised associated official FEMA Flood Insurance Rate Maps (FIRMs) with local community and State endorsement.
Toll Brothers – Fayetteville Road Assemblage Conditional Letter of Map Revision (CLOMR) and Culvert Design: Project Engineer for assessment of impact of proposed double rectangular box roadway culvert crossing on Southwest Creek 100-year FEMA floodplain in Durham, NC. Modified the effective FEMA HEC-RAS hydraulic model to include proposed development and quantify changes in flood elevation and extent. Designed roadway culvert crossing according to inundation, HW/D, and erosion control requirements. Revised associated official FEMA Flood Insurance Rate Maps (FIRMs) with local community and State endorsement.
M/I Homes – Ballentine Flood Studies and Culvert Design: Project Engineer for risk analysis of flood damage at residential multi-family development in Charlotte, NC. Developed hydrologic models using HEC-HMS and USGS regression equations to develop flow rates for the 100-year event. Constructed a hydraulic model using HEC-RAS in order to quantify flood elevation. Mapped areas of inundation from the 100-year event flood elevation using survey and GIS.
