KEY PERSONNEL RESUMES <br />* Refer to page 9 for <br />project description <br />MIGUEL HERNANDEZ, PE, PLS, QSD <br />Project Manager - Huitt-Zollars <br />Miguel Hernandez has more than 26 years of experience in Public Works and is <br />proficient with the design of streets, highways, sewer, water, storm drain, grading, <br />hydrology and hydraulics. His experience combined with his ability to communicate <br />will make him a valuable asset to a project. As a Project Manager he will be helpful <br />in coordinating all design inclinations and finding the appropriate balance. When <br />critical deadlines need to be met his proven ability to work under pressure will be <br />invaluable. <br />RELEVANT PROJECT EXPERIENCE <br />Citywide Sanitary Sewer and Domestic Improvements - Santa Ana, CA* <br />LA Harbor College 3 Stormwater Project - Wilmington, CA <br />LACCD is required to comply with the upcoming Phase II MS4 Permit post - <br />construction requirements. Plans, specifications, estimates, and construction <br />support were provided for 2-acre-feet of subsurface infiltration chambers and 15,000 <br />SF of raised medians retrofitted with biofiltration systems, associated storm drain, <br />sewer, parking lot, electrical, architectural improvements. Upgrades to improve <br />aging utility infrastructure, and incorporate American with Disability Act requirements <br />on campuses. Structural, accessibility, and fire & life safety requirements from DSA <br />are addressed as part of the design. <br />Pierce, Valley and Harbor Colleges Sewer Assessments <br />The assessments brought together the expertise and knowledge of LACCD and HZ <br />civil engineering staff to provide a focused analysis of the sewer system at Pierce, <br />Valley and Harbor Colleges. The services include comprehensive reviews of past <br />work, plans, and a site visit to evaluate over 40,000 linear feet of sewer line and <br />manholes. To determine the integrity of sewer pipes our staff reviewed past reports, <br />watched CCTV video, analyzed photos, considered recommendations in the <br />sewer pipe engineering manuals, interviewed plumbing staff at each college, and <br />performed visual inspections. Ourwork involved planning for complete rehabilitation <br />that extended the life of the current sewer system. It also delivered engineer's <br />estimates of probable construction cost to restore the existing infrastructure in the <br />most cost-effective manner. Our proposed planning alternatives build on existing <br />information, assume common engineering practices, and assume common soil <br />compaction practices to install sewer pipe and construct sewer manholes. <br />Oakmont Park and Live Oak Canyon Creek Design Evaluation and Repair - <br />Redlands, CA <br />Huitt-Zollars performed hydrologic, hydraulic, geomorphic, and geotechnical <br />investigations were performed to characterize the conditions that have led to the <br />existing degradation of the creek bed and lateral erosion of the creek banks. In <br />Oakmont Park, upstream development increased the higher discharge rates and <br />limited sediment supply causing lateral meander movement. Existing check dams <br />have failed due to a lack of embedment that would have otherwise helped protect <br />against undermining. Repairs to further erode laterally towards Live Oak Canyon <br />Road. Huitt-Zollars identified a preferred erosion control alternative based on <br />constructibility, cost, environmental constraints, and effectiveness. The preparation <br />of plans, specifications, estimates mitigates the conditions by specifying riprap to <br />protect the toe of Live Oak Canyon Creek, and a series of 4-foot tall grade control <br />structures made of gabions constructed at 70-foot intervals. <br />HLIITTZOLLARS <br />City of Santa On -Call Water Resources Engineering Services RFP No. 22-002 <br />
