Engineering Projects

Rainier View Water Company

Apex continues to provide ongoing engineering services, which includes setting up developer extension program for the utility, design and coordination of multiple extensions for multiple water systems, coordination of directives and orders from Department of Health, site acquisition, and design of wells and storage facilities. To date, 35 separate waterline extension projects have been completed.  Apex has also assisted with the preparation of a comprehensive master water system plan for Rainier View Water Company.

City of University Place

As part of the on-call contract with the City, Apex has performed many engineering services. Apex Engineering has provided engineering support for the new Town Center complex. Apex has also provided engineering and surveying services for several street intersection, sidewalk improvement, and sanitary and storm water analysis studies and engineering design projects.

Sunrise Master Planned Community

Apex Engineering has prepared a Storm Drainage Master Plan for the southerly 766 acres of the Sunrise Master Planned Community (MPC) including offsite tributary areas of another 260 acres. The project is located within the drainage basin of Lorenz Creek, a feeder of Horsehaven Creek that is one of the six primary tributaries of the mid-Puyallup River basin in Pierce County.

The Storm Drainage Master Plan evaluated the 1,026 acre drainage basin for pre-development drainage patterns and post-development storm drainage impacts by dividing the basin into twelve (12) sub–basins and analyzing each sub-basin individually and cumulatively. Total runoff from the sub-basins were calculated using current modeling software with future development based on proposed land use densities for the Sunrise MPC.

Within the Sunrise master plan community lies a 134+ acre wetland and related buffer; known as Wetland 41, this large tract of land has been set aside as a pristine, natural habitat and open-space area.  Wetland 41 averages approximately 600 feet in width and more than 6,000 feet in length. Wetland 41 represents the low depression of an 835+ acre drainage basin.  As the master plan is developed a total of 6 large regional ponds have been proposed to treat, detain and discharge stormwater to this basin.

Jubilee Master Planned Community

As part of the premier active-adult community in South Puget Sound, Apex Engineering has been providing all of the civil engineering design improvements both within the 3,600-unit residential community and in the adjacent commercial and residential neighborhoods in Lacey, Washington to accommodate the Jubilee residents.  In addition to the civil design of the residential communities within Jubilee, Apex has also designed all of the regional storm, sanitary sewer and road network facilities that also serve existing residential and commercial needs.

Belfair Water District

Apex continues to provide planning and engineering services for engineering design and construction of approximately 3100 feet of water main and pressure reducing station.  The location of this project has required Apex to work with all local agencies in conjunction with the USDA to obtain permits and funding.  The project will connect two pressure zones and will help increase fire flow throughout the District’s service area.
