KEY PERSONNEL RESUMES * Refer to page 9 for project description MIGUEL HERNANDEZ, PE, PLS, QSD Project Manager - Huitt-Zollars Miguel Hernandez has more than 26 years of experience in Public Works and is proficient with the design of streets, highways, sewer, water, storm drain, grading, hydrology and hydraulics. His experience combined with his ability to communicate will make him a valuable asset to a project. As a Project Manager he will be helpful in coordinating all design inclinations and finding the appropriate balance. When critical deadlines need to be met his proven ability to work under pressure will be invaluable. RELEVANT PROJECT EXPERIENCE Citywide Sanitary Sewer and Domestic Improvements - Santa Ana, CA* LA Harbor College 3 Stormwater Project - Wilmington, CA LACCD is required to comply with the upcoming Phase II MS4 Permit post - construction requirements. Plans, specifications, estimates, and construction support were provided for 2-acre-feet of subsurface infiltration chambers and 15,000 SF of raised medians retrofitted with biofiltration systems, associated storm drain, sewer, parking lot, electrical, architectural improvements. Upgrades to improve aging utility infrastructure, and incorporate American with Disability Act requirements on campuses. Structural, accessibility, and fire & life safety requirements from DSA are addressed as part of the design. Pierce, Valley and Harbor Colleges Sewer Assessments The assessments brought together the expertise and knowledge of LACCD and HZ civil engineering staff to provide a focused analysis of the sewer system at Pierce, Valley and Harbor Colleges. The services include comprehensive reviews of past work, plans, and a site visit to evaluate over 40,000 linear feet of sewer line and manholes. To determine the integrity of sewer pipes our staff reviewed past reports, watched CCTV video, analyzed photos, considered recommendations in the sewer pipe engineering manuals, interviewed plumbing staff at each college, and performed visual inspections. Ourwork involved planning for complete rehabilitation that extended the life of the current sewer system. It also delivered engineer's estimates of probable construction cost to restore the existing infrastructure in the most cost-effective manner. Our proposed planning alternatives build on existing information, assume common engineering practices, and assume common soil compaction practices to install sewer pipe and construct sewer manholes. Oakmont Park and Live Oak Canyon Creek Design Evaluation and Repair - Redlands, CA Huitt-Zollars performed hydrologic, hydraulic, geomorphic, and geotechnical investigations were performed to characterize the conditions that have led to the existing degradation of the creek bed and lateral erosion of the creek banks. In Oakmont Park, upstream development increased the higher discharge rates and limited sediment supply causing lateral meander movement. Existing check dams have failed due to a lack of embedment that would have otherwise helped protect against undermining. Repairs to further erode laterally towards Live Oak Canyon Road. Huitt-Zollars identified a preferred erosion control alternative based on constructibility, cost, environmental constraints, and effectiveness. The preparation of plans, specifications, estimates mitigates the conditions by specifying riprap to protect the toe of Live Oak Canyon Creek, and a series of 4-foot tall grade control structures made of gabions constructed at 70-foot intervals.
