CITY PARK RECLAIMED WATERLINE
KWC Engineers prepared plans in 2012 for the design of 4,300 lineal feet of 12-inch diameter reclaimed water main pipeline in Joy Street from Harrison south in E. Grand Blvd. and east in Quarry Street for the City. This work effort included the design of jack and bore operations underneath the B.N. & S.F. railroad and an open trench casing installation underneath the 91 freeway bridge at E. Grand Blvd. KWC’s team performed the geotechnical borings and 25 potholes for this project. KWC prepared the preliminary design alignment based on field walks and our utility research. Our design had to accommodate numerous utility crossings and conflicts that existed, along with a future 60” storm drain in the pipeline corridor. This project provided Reclaimed Water to the existing City Park on Quarry Street to be more environmentally friendly.
We have recently submitted as-built plans following the completion of construction. We prepared the project specifications, cost estimate and bid schedule. KWC was responsible for obtaining permits from Caltrans, B.N. & S.F. railroad, and coordinating the design with other stakeholders, such as Riverside County Transportation Commission. The project was constructed on-time and under budget.
FOOTHILL PARKWAY WATERLINES
TrI point homes
KWC recently prepared plans for a proposed 16” offsite waterline in Foothill Parkway between Bedford Canyon Road and State Street as well as revisions to the existing offsite 16” reclaimed waterline to add fire hydrants, service laterals and to avoid a proposed storm drain pipe. KWC also prepared offsite sewer improvement plans including jack and boring under Interstate 15, onsite water and sewer plans and coordinated preparation of onsite reclaimed water system for approvals through the City of Corona, County of Riverside, MWD and Caltrans.
CORONA MALL PARKING LOT REHABILITATION
City of Corona Public Works Department
KWC finished a very time sensitive project for the City of Corona that included field survey, base mapping, existing topographic, demolition plans, paving rehabilitation and parking lot light plan preparation. The project required evaluating existing site features and utilities, to determine removals, relocations, and protection of facilities. The City proposes to overlay the parking lot with minimal grinding therefore evaluation of existing curbs, gutters, drainage inlets and pedestrian path of travel was necessary in addition to staying within the project budget.
WATERLINES IN THE SOUTHWEST QUADRANT OF GRAND BOULEVARD
KWC finalized waterline improvement plans and technical specifications for phase 1 (5,000 lf) and prepared 90% plans for the remaining portion (8,500 lf) in 2015. The project required coordination of proposed facilities with Corona Regional Medical Center, Library, Schools and Public Buildings. KWC coordinated over 200 crossings of existing utilities with a combination of potholing and utility locating, as well as preparation of Soil’s Report, CEQA documents, Traffic Report, and Traffic Control Plans. Phase 1 of the project is currently under construction.
ONTARIO AVENUE ZONE 4 WATERLINE
Design of approximately 2,580 lf of proposed 12-inch waterline located in Ontario Ave. between Buena Vista and Taylor Ave. in the City of Corona. This waterline was constructed to address low pressure issues within the immediate area. The new pipeline was installed in a location that minimizes utility conflicts and construction cost.
WATER MAIN REPLACEMENT IN LAKELAND VILLAGE
LAKE ELSINORE, CA
KWC prepared plans and full specifications in 2013 for the replacement of existing waterlines and residential services and meters for five (5) streets within Lakeland Village, County of Riverside. The scope of work included utility research, field topography, 27 potholes, designing proposed water system in such a way to leave the existing system operational until the proposed system was operational. The project is currently under construction.
Nichols Road Lift Station
Lake Elsinore, CA
Design and survey of the Nichols Temporary Lift Station on 0.5 acres of land, including providing the construction survey of 5,480 feet of 8” gravity sewer line going into the lift station and 1,500 feet of sewer force main leaving the lift station to the existing sewer located within Collier Avenue. Work included the establishment of control, preparation of field staking packages, staking of the sewer gravity lines, sewer force main and survey of the lift station facilities.
MAIN STREET STORM DRAIN
City of Corona Public Works Department
KWC recently (2009-2012) designed street and storm drain improvements to Main Street between 8th and 11th streets. KWC’s work scope included performing a hydraulic analysis of the existing deficient storm drain facilities in Main Street from Railroad Street south to 11th Street in order to determine ultimate storm drain pipe sizes. Our work included developing a preliminary alignment study, field survey, coordinating pothole surveys, and preparation of construction drawings for approximately 1,320 lineal feet of proposed 18” and 24” storm drain between 8th and 11th Street. Working with City staff, the alignment and catch basin configurations were selected to minimize utility conflicts and traffic congestion in Main Street.
COUNTRY CLUB HEIGHTS WATERLINE IMPROVEMENTS
Lake Elsinore, CA
KWC recently (2013) designed water improvement plans for seven (7) sites in older neighborhoods with existing narrow, hilly, curved streets to improve the hydraulic looping and connectivity of the water system.
