PROJECTS
EXPERIENCES WITH KEY PROJECTS:
Flood Study of Calaveras Creek Watershed, San Antonio, Texas- Developed hydrologic (HEC-HMS) and hydraulic modeling (HEC-RAS). The study was submitted to FEMA in support of Conditional Letter of Map Revision (CLOMR) and Letter of Map Revision (LOMR).
Flood study/ Selma Stage Stop, Selma, Texas- Analyzed the existing floodplain for the development of Selma Stage Stop.
Flood Study for French Creek, San Antonio, Texas- Developed hydraulic modeling (HEC-RAS). The study was submitted to FEMA in support of a Letter of Map Revision (LOMR).
Drainage Study/ Highland Hills Development, San Antonio, Texas (15.0 acre Tract) - Prepared the Storm Water Management Plan which involved the existing Digital Flood Insurance Rate Map (DFIRM) models (hydrologic and hydraulic) for 833.0 acre drainage area applicable to the Hospital Creek in Upper San Antonio River Watershed. The drainage study includes a low water crossing analysis. Study also includes a detailed analysis of a low water crossing.
Drainage Study/ McDonough Master Development Plan, San Antonio, Texas (104.0 acre tract) - Prepared the Master Development Plan (MDP) which includes the detailed drainage analysis of Upper Leon Creek Watershed. The hydrologic and hydraulic models for DFIRM Study were used in the drainage analysis.
Drainage Study/ McDonough 36.0 Acre MDP, San Antonio, Texas- Prepared the Storm Water Management Plan which involved the analysis of DFIRM hydrologic and hydraulic models for 560.0 acre drainage area applicable to the Salado Creek in Upper Salado Creek Watershed.
Drainage Study/ The Estates at Golf Valley, San Antonio, Texas- Prepared the Storm Water Management Plan which involved the analysis of DFIRM hydrologic and hydraulic models for 600 acre drainage area applicable to the Cibolo Creek in Cibolo Creek Watershed.
Drainage Study/ McCombs- Culebra & Tezel Tract, San Antonio, Texas (24.0 acre tract) –Analyzed the Culebra Watershed in conjunction with the adverse impact analysis for this commercial development and design the hydraulic infrastructures as required for the development.
Drainage Study/ Southern Hills Subdivision, San Antonio, Texas- Completed the detailed hydrologic and hydraulic analysis applicable to Calaveras Creek watershed for the development.
Old Castle Precast Construction Site Development, San Antonio, Texas- Performed a low water crossing analysis.
Esperanza Road Drainage Improvement Project, Laredo, Texas- Completed hydrologic and hydraulic analysis for a 160.0 acre watershed in order to identify the cause of flooding problems, and designed the new drainage system, estimated the project cost and reviewed the bid proposals.
Drainage Study/ Winfield Master Development Plan, Laredo, Texas- Performed detailed drainage study for the 320.0 acre watershed, analyzed the existing culverts under Loop 20 (TxDOT) within the relevant watershed and provided designs for the modified channel in the downstream side. The study also included several detention pond designs in order to eliminate the downstream impact from the developments.
South Texas Detention Pond Complex, Correctional Services Corporation, Pearsall, Texas- Analyzed a 120.0 acre watershed and provided the hydraulic designs including a detention pond modeling.
Loop 20/Sinatra Culvert Addition, Laredo, Texas- Performed a 200.0 acre watershed analysis and provided recommendation for additional culverts under Loop 20 (TxDOT) with its design.
Kingdom Hall at Lawndale, San Antonio, Texas- Analyzed the watershed and designed the detention pond for the Kingdom Hall with the site grading.
Jacaman Ranch Subdivision- Laredo, Texas- Performed a detailed drainage study which includes a detention pond design.
Laspalmas C.J.W. Subdivision, San Antonio, Texas- Designed the detention pond for the church with the site grading
