<br />new CMU block well building and sodium hypochlorite building, sodium
<br />hypochlorite disinfection facility, approximately 3,300 linear feet of
<br />16-inch pipe from Well No. 32 to John Garthe Reservoir, bore and jack
<br />under channel crossing and site improvements.

<br />Years with Tetra Tech:
<br />West Chandler Well, South Croddy Well and Pipeline, Mesa Water P 29
<br />District, Costa Mesa, CA. 2017 - Present. Project Director for the
<br />drilling and equipping of Well Nos. 12 and 13, two new potable water wells (approximately 1,050 feet
<br />deep), to provide additional local water reliability to the customers of Mesa Water District. The project
<br />involves the demolition of existing buildings at Well Nos. 12 and 13 properties within the City of Santa
<br />Ana. Both wells are located outside of Mesa Water's service area and will require the construction of
<br />approximately 4,400 feet of pipeline to connect the proposed wells to Mesa Water's existing system.
<br />Each well site includes the construction of a vertical turbine pump estimated to produce approximately
<br />3,000 gpm, new CMU block wall building, new chemical storage facility, sodium hypochlorite and aqua
<br />ammonia disinfection facility, and site and landscaping improvements.
<br />La Palma Avenue and Tustin Avenue Watermain Replacements at OCTA Crossing, City of
<br />Anaheim, CA. 2019 - Ongoing. Project Director. The OCTA planned to construct an additional railroad
<br />track for the Metrolink within its existing right-of-way as part of the Anaheim Canyon Station Metrolink
<br />Project. The new tracks cross City of Anaheim water mains at La Palma Avenue and Tustin Avenue
<br />and therefore the mains must be rerouted and placed within a steel casing. Tetra Tech prepared plans
<br />and specifications to replace the existing 36-inch CCP with a 36-inch steel in a 48-inch steel casing in
<br />La Palma Avenue, the existing 12-inch CIP with a 12-inch DIP in a 24-inch steel casing in La Palma
<br />Avenue, and the existing 12-inch CIP with a 12-inch DIP in a 24-inch steel casing in Tustin Avenue.
<br />The project also included coordination with OCTA.
<br />Regional Lift Station Force Main Replacement, Moulton Niguel Water District, Aliso Viejo, CA.
<br />2017 - Ongoing. Project Manager. Mr. Epperson is the project manager providing engineering services
<br />for the replacement of approximately 15,000 linear feet of 20-inch and 24-inch Techite sewer force
<br />main with Laguna Niguel Regional Park. Regional Lift Station and Force Mains are critical wastewater
<br />facilities that pump flow from MNWD sewer collection system to South Orange County Wastewater
<br />Authority Regional Treatment Plant. The replacement force main consists of dual 24-inch pipeline
<br />approximately 8,000 feet length and will be constructed with Laguna Niguel Regional Park. Scope of
<br />services include preliminary design, final design and construction phase services.
