JONIS C, SMITH, PE, CFM — CONTINUFID
<br />over -excavation and re -compaction of 80,000 cubic yards of onsite material was required to stabilize
<br />subsurface soils from existing ground level to the underlying bedrock To construct the above grade
<br />berms, the project will import approximately 50,000 cubic yards; Dudek is coordinating with the District to
<br />dentify, select„ and pre -negotiate an offsite borrow pt for the Imported material. Other improvements
<br />include recycled water pump stations at the WRF site and Charlan Road, coordinated to allow parallel
<br />operation in a common 5,000 -ft long forcemaln to the neighboring Woods Valley Golf Course,
<br />Harveston Lake, Lennar Homes, Temecula, California. Project Manager and Project Engineer for
<br />proposed 10 acre (150 ac -ft) lake for the then proposed residential community known as Harveston. Mr.
<br />Smith designed the lake liner, filtration, circulation, and aeration systems. He prepared the lake grading
<br />plan set with all the lake operational features and published a lake Operations Manual to give the lake
<br />owner guidance on lake maintenance and operations procedures.
<br />Heritage Park Lake, City of Cerritos, Cerritos, California. Project Manager and Project Engineer for
<br />proposed 4 acre (24 ac -ft) lake for the then proposed renovation of the community park, Mr. Smith
<br />designed the lake liner, filtration, circulation, and aeration systems, He prepared the lake grading plan set
<br />with all the lake operational features and published a lake operations manual for the lake owner.
<br />North Trumble Recycled Water Storage Pond, Eastern Municipal Water District, Perris, California.
<br />Mr, Smith served as the lead project engineer for the pond design portion for this project, The project
<br />consisted of design for two new recycled water ponds that will provide the District with 1,500 acre-feet
<br />(489 million gallons) of additional seasonal storage capacity to allow the District to use more recycled
<br />water within Its service area during the high -demand summer, months. Features of the new ponds include
<br />three 2,000 gpm floating pump stations with 150 hp vertical turbine pumps, approximately 2,500 If of 16 -
<br />inch to 36 -inch inlet and discharge piping, and 36 -inch diameter steel pipelines and isolation valves to
<br />interconnect the new ponds to each other and to the existing adjacent Trumble Road Recycled Water
<br />Pond. Access roads to the bottom of the ponds with landing platforms for cranes will also be provided.
<br />The project also includes improvements to two existing recycled water ponds, the 117 MG Case Road Pond
<br />and the 50 MG Watson Road Pond. These improvements include new 2,000 gpm floating pump stations
<br />and associated inlet and discharge piping, electrical and SCADA system upgrades, and deepening of Case
<br />Road Pond to optimize the storage capacity at that site.
<br />WRP7 Percolation Ponds, Coachella Valley Water District, Coachella, California. Project Engineer for
<br />design of the 58 -MG percolation pond. The project goal was to maximlze the disposal capacity of onsite
<br />percolation ponds, thereby minimizing the District's reliance on offslte percolation ponds which are subject
<br />to restrictions during wet weather events. A comprehensive geotechnical investigation was prepared to
<br />analyze hydraulic conductivity of the surface soils, general geology, and local hydrogeology. This analysis
<br />identified soil clogging and subterranean groundwater barriers as restrictions to the onsite percolation
<br />rate, with varying expected percolation rate across the plant site. This evaluation was developed into a
<br />percolation pond improvement strategy that Includes reconfiguring the ponds to maximize percolation
<br />capacity and onsite storage volume.
<br />Fletcher Percolation Basin, Orange County Water District, Orange, California. Project, Manager and
<br />Project Engineer for the proposed redevelopment and repurposing of a150 ac -ft percolation basin for
<br />OCWD. Mr, Smith prepared a preliminary design study to determine the basin storage and percolation
<br />capacity. The basin was preliminarily designed to operate as a dual use facility providing both stormwater
<br />detention and groundwater recharge. The basin will also provide additional storage capacity in the OCWD
<br />Riverview Basin system adjacent to the Santa Ana River. The basin was preliminarily designed to function as
<br />a deep recharge basin with a maximum depth of 35 -ft. The basin bottom and sided below the permanent
<br />storage pool were designed with large particle size soil slopes to allow for maximum recharge.
