Client: Prologis & REDA
WLG is providing Professional Engineering Design to both Prologis and Real Estate Development Associates (REDA) for the City of Ontario’s New Model Colony (NMC) - Phase I, Master Planned Facilities located in South Ontario. Prologis is currently under construction for a 1.2 million-square-foot warehouse, while REDA is under construction with their 1st phase; a 1.2 million-square-foot warehouse. Both projects have a total area of approximately 165-acres. WLG is the prime on these two projects, providing on-site and off-site engineering services for Prologis and off-site services for REDA, which includes the design and coordination of three major roadways (Merrill, Carpenter, and Eucalyptus Avenues) including all the associated master planned facilities. Facilities contain both wet and dry utilities including a double 12’Wx10’H RCB storm drain from Carpenter Avenue to the Cucamonga Creek Channel within Merrill Avenue that ties into the Cucamonga Creek Channel; approximately two miles of domestic water and recycled water lines (REDA Loop); Carpenter Avenue to Archibald Avenue within Merrill Avenue and Eucalyptus Avenue including jack and bore design to go under the Cucamonga Creek Channel; a new bridge at Eucalyptus Avenue and bridge expansion at Merrill Avenue over the Cucamonga Creek Channel; and the relocation of IEUA’s 30” recycled water transmission main and pressure reducing station within Carpenter Avenue. The on-site storm drain mitigation system pictured includes two underground infiltration basins with 96” diameter perforated CMP pipes throughout. The northern system is 1,032 feet by 74 feet that have a volume capacity of 153,357 cubic feet. The southern system is 1174 feet by 74 feet with a volume capacity of 587,870 cubic feet. Design and coordination efforts include agencies such as OMUC, the City of Ontario’s Planning and Engineering Departments, IEUA, DDW, CDA, SBCFCD, USACE, the Cities of Chino and Eastvale, and private developers and their sub-consultants.

Client: Utica Business Park
Location: Rancho Cucamonga, CA - This three-acre commercial development required boundary analysis, topographic surveying and final parcel map, preliminary and final engineering, including grading and drainage, off-site street improvements, WQMP, SWPPP, utility connection design, permitting assistance, construction staking, and construction support.
Client: Charles Company
Location: Monterey Park Contributing to the growing improvements in Monterey Park, CA, the Charles Company is transforming under-utilized lots into large mixed-use opportunities with new retail and hotel accommodations. Providing multiple green spaces with modern transit opportunities the project will improve the aesthetics of the area creating a dynamic atmosphere for the public. The site will include a 5-7 story hotel with apartment living and abundant ground floor commercial uses. WLG has been spearheading the entitlements process for the project, which includes preparing the tentative tract maps, surveying, lot line adjustments, site plan review, conditional use permits, and variances.
Client: Bakken Industrial Properties
Location: Ontario, CA WLG processed all record maps and furnished design engineering services associated with this 10.5-acre development in the City of Ontario. We provided all permit processing, construction staking, and construction support.
Client: Tricor Southwest
Location: Chino Hills, CA WLG's involvement in this six-acre commercial site development project included surveying and mapping, preliminary and final civil engineering design, stormwater management, retention basin, construction staking, site grading, utilities, infrastructure, and street improvements on Peyton Drive and Chino Hills Blvd. WLG worked with the various agencies to mitigate issues and obtain final permits for construction.
Client: Turner Construction Corp.
Location: Alhambra, CA WLG was retained by Turner Construction for this project. WLG's involvement included reviewing civil, architectural, and structural plans as well as generating RFIs for any discrepancies found with regards to the building, drainage, and site layout. WLG surveyed the boundary and conducted a design survey on existing improvements in order to review existing with proposed improvements. Data was analyzed and any grading enhancements were field designed as needed. WLG also provided the construction surveying and staking required for the construction of the building, streets, drainage structures, utilities, and parking lots. WLG engineers also updated the drainage and grading plans with as-built information, which was required by SCE and the City of Alhambra.
