Upper Brushy Creek FRS No. 13A, Round Rock, TX Principal design engineer and engineer of record for the final design of rehabilitation of a low hazard dam upgraded to high hazard. Prepared hydraulic, hydrologic and structural designs of modifications to meet current NRCS TR-60 high hazard requirements, which included addition of principal spillway conduit, hood inlet trashrack structure, and impact basin outlet and parapet wall. Construction drawings, specifications, cost estimates, and contract documents were prepared. Project has been constructed.

Muddy Fork Illinois MPD 4, Prairie Grove, AR Planning engineer in development of Watershed Work Plan Supplement and EA. Performed evaluation of alternates in accordance with P&G and National Watersheds Manual using SITES program to meet site and easement constraints and NRCS TR-60 criteria for the rehabilitation of a low hazard water supply and flood control dam upgraded to high hazard. Selected alternate is RCC primary auxiliary spillway and raised top of dam. Principal design engineer and engineer of record for the final design, plans, specifications, cost estimate and contract documents for this project. Construction has not commenced.

Caney Coon MPD 2, Sallisaw Creek FWRS 32, 18M, and 26; Cottonwood Creek FWRS 15 and 16 M&E Consultants partnered with URS Corporation in the design of rehabilitation of these six dams. Designed the principal spillway systems for these six projects to meet NRCS TR-60 and State of Oklahoma criteria. Reviewed and checked final design, plans, specifications and cost estimates prepared by others. Advised URS personnel on NRCS criteria and procedures.

Sole Proprietorship, William H. Erion, Civil Engineer (1999 – 2001)

Elm Fork 19 MP, Muenster, TX Prepared reservoir operation study using NRCS TR-19 and RESOP for water supply dam and reservoir to establish the optimum storage to meet the water supply demand for Muenster, Texas. Prepared planning information on the water supply portion of the project. Flood routing, using SITES program was performed to establish hydraulic and structural proportions. Cost estimates were made and reports evaluating the monetary benefits accruing to the development of municipal and industrial water supply for this project were prepared per NRCS National Watersheds Manual and Principals and Guidelines which was used by NRCS in developing the final EA. Presented and defended these plans at interagency meetings during the 404 permit review and provided input to the development of the mitigation plans.
