Huitt-Zollars provided preliminary site development studies, water quality management plan, grading plans, drainage studies, sewer and water plans along with underground fire service plans. The project called for on-site and off-site improvement plans in the construction of an 11,000-seat entertainment complex. The facility can be reconfigured for a variety of events via flexible seating capacity, providing a unique and powerful venue for regional events. The project was successfully executed on a tight schedule.

Huitt-Zollars assisted Shea Properties in preliminary and final construction documents for the 600,000-SF lifestyle center, located on 64-acres. The open air lifestyle center is anchored by major retailers, and features 17 buildings with seven out parcels. This project was a continuation of the Riverpark project. Huitt-Zollars prepared rough grading plans, precise grading plans, ALTA surveys, address maps, wet utility plans, and lot line adjustments for the project.

Huitt-Zollars prepared on-site civil construction plans and horizontal control plans for this 50-acre retail commercial outlet center. Plans were prepared for precise grading, storm drainage, signage and striping, retaining walls, guard rail barriers, erosion and sediment control. Additional plans were prepared for domestic water and sanitary sewer systems. Project design included 21,000 LF of storm drains; 8,800 LF of domestic water pipes; and 6,700 LF of sewer pipes. Project challenges included (and were not limited to) designing an off-site sewer main down a 70-foot-high 2:1 slope.

Huitt-Zollars provided preliminary and final engineering services, preparation of conceptual grading, drainage and utility plan, preliminary water quality management plan, preliminary drainage study, and construction administration for the 57,000 square-foot commercial/retail development and parking lot. Final construction drawings included precise grading, storm drain, sewer, water, firewater, and associated support calculations. Site design included a 10,000 cubic-foot underground infiltration chamber system that reduces stormwater outflow and removes potential pollutants from stormwater

This project consisted of rehabilitating the existing over 3,000-SF Presidential Suite, re-theming the lobbies of the three towers that make up the hotel, and re-theming three existing buildings within the central courtyard. All of the existing finishes, furnishings, and fixtures within the Presidential Suite were removed and replaced with new.

Huitt-Zollars provided preliminary and final grading plans, utility plans, storm drain plans and calculations, hydrology and hydraulics, a water quality management plan, storm water pollution prevention plan, parcel and condo maps, road dedications, and site planning services. The project involved 14 executive office buildings that range from 2,500-square-foot single-story units up to 20,000-square-foot, two-story units. Huitt-Zollars designed several underground storm chamber systems, allowing storm water storage that percolates into underlying soil. The system helps recharge the ground wa

Huitt-Zollars provided site plan layout, preliminary grading and drainage design and construction documents for a two-story, 30,000 square-foot office building and parking lot located on approximately 1.5 acres. The site design included the use of porous concrete pavement to help reduce and treat stormwater runoff prior to releasing runoff into the public right-of-way. Also, to minimize the use of underground storm drain systems, a natural drainage swale was utilized on-site to help convey stormwater runoff around the building and to the adjacent roadway.

The Koll Center Spectrum Office Parks I, II, and III are located on three distinct parcels totaling 31 acres. The projects consisted of more than 436,000 square-foot of office space within 28 separate buildings. Huitt-Zollars prepared preliminary engineering documents necessary for planning commission approval, plus preliminary grading, drainage and utility concepts, a preconstruction ALTA survey, and boundary surveys.

Huitt-Zollars provided site plan layout, preliminary grading, drainage design, and construction documents for the development of two, two-story, 16,000 square-foot office buildings and parking lots located on approximately three acres. The site design included the use of natural drainage swales, underground infiltration chambers and catch basin filters to help reduce and treat stormwater runoff prior to releasing runoff into the public right-of-way.

Huitt-Zollars provided site design including grading and drainage, a sewer and water plan, and public street improvement plan revisions. Azusa Court is a two-story office building and parking lot fronting the Empire Lakes Golf Course in the City of Rancho Cucamonga.
