portion of the San Fernando Valley in order to reduce
<br />the potential for flooding, improves stormwater quality,
<br />increases water supplies through stormwater capture,
<br />and provides recreational, social, and economic benefits.
<br />The project consisted of the installation of underground
<br />infiltration galleries, dry wells, catch basins, diversion
<br />structures, pump stations, hydrodynamic separator units,
<br />flow measuring devices, supervisory control and data
<br />acquisition, educational signage, and park restoration/
<br />improvements. Services included project coordination,
<br />background review, permit acquisition, coordination with
<br />Underground Service Alert for utility markout, subsurface
<br />evaluation,15 cone penetration tests (CPTs) to depths
<br />of up to approximately 50 feet below the ground surface,
<br />percolation testing (falling head and constant head testing)
<br />in 15 borings, laboratory testing of collected samples,
<br />analytical characterization and disposal of drummed
<br />soil, compilation and analysis of the collected data, and
<br />preparation of geotechnical reports.
<br />County of Los Angeles, Green Streets Master Plan
<br />Part 2 (Principal Geologist)
<br />Michael performed a geotechnical study for the County of
<br />Los Angeles Department of Public Works' Green Streets
<br />Master Plan Part 2 Project. The purpose of our services
<br />was to provide geotechnical subsurface and infiltration
<br />data for five sites located within the cities of Westmont,
<br />Altadena, Rowland Heights, Valinda, and Agoura Hills,
<br />California. Services included a subsurface evaluation and
<br />extensive geotechnical laboratory testing was performed
<br />on the subsurface soil samples collected at each site,
<br />Constant and falling head infiltration testing was performed
<br />in each drywell using a continuous rotation of three
<br />10,000-gallon water trucks. The flow rates were measured
<br />using a digital flowmeter and continuous datalogger and
<br />manual readings were collected during the testing. Total
<br />volumes of discharged infiltration water at each drywell
<br />site ranged from 17,000 to 56,000 gallons. Infiltration
<br />testing results were presented in graphical format in a
<br />second data report for the project.
<br />Cypress Storm Drain Replacement Project, Cypress,
<br />CA (Principal GeologistlProject Manager)
<br />Michael provided a geotechnical evaluation for the Walker
<br />Street, Aspen Street and Hanover Drive Storm Drain
<br />Replacement project located in Cypress, California. The
<br />purpose of the study was to evaluate the subsurface soil
<br />and geologic conditions along the project alignment and
<br />to provide geotechnical recommendations for design and
<br />construction of the new storm drains.
<br />Myra Avenue Storm Drain and Sewer Improvements,
<br />Cypress, CA (Principal GeologistlProject Manager)
<br />Michael provided geotechnical consulting services for the
<br />Myra Avenue Pump Station No. 3, Storm Drain and Sewer
<br />Improvement project located in Cypress, California. The
<br />purpose of the geotechnical services were to evaluate the
<br />geotechnical characteristics of the subsurface soils as they
<br />pertain to the design and construction of the proposed
<br />pump station, storm drains, laterals, catch basins, and
<br />sewer replacements.
<br />Orange County Sanitation District/Plant No. 2, Job
<br />P2.105, Digester Ferric Chloride System Rehabilitation
<br />(Project Geologist)
<br />Michael served as project geologist providing a
<br />geotechnical evaluation report for final design. Services
<br />included review of historical background documents,
<br />exploratory borings, laboratory testing, and geotechnical
<br />engineering, The geotechnical report addressed geologic
<br />conditions and seismic hazards, groundwater, seismic
<br />design parameters, site earthwork and foundations.
<br />Recommendations were presented for structure pad
<br />earthwork, mat foundation designs, trenching and shoring,
<br />lateral earth pressures, and construction dewatering.
<br />Orange County Sanitation District/Magnolia Trunk
<br />Sewer Rehabilitation (Project Geologist)
<br />Michael served as project geologist for a design -build
<br />project to rehabilitate the trunk sewer line utilizing the slip
<br />lining technique. The slip lining technique involves the
<br />excavation of access pits through relatively soft alluvial soil
<br />below groundwater to expose the top of the sewer pipeline
<br />for installation of the liner. Services included geotechnical
<br />and environmental consulting services during the design
<br />phase that included preparation of geotechnical evaluation
<br />reports, environmental screening for soil and groundwater
<br />contamination Including aerially deposited lead,
<br />performance of pre -construction site condition surveys,
<br />and preparation of a vibration monitoring plan,
<br />County of Orange/Rossmoor Storm Channel
<br />Improvements (Principal Geologist/Project Manager)
<br />Michael provided geotechnical consulting services for
<br />the Rossmoor Storm Channel Improvements Project.
<br />The project involved the design of three alternative
<br />improvement concepts for the channel that has
<br />deteriorated with age and threatens adjacent properties
<br />with overflows. The improvement alternatives included
<br />reconstructing the channel walls with vertical retaining
<br />walls and/or slopes at various inclinations. The project
<br />was performed in collaboration with Orange County Public
<br />Works and Orange County Flood Control District.
