Site Plans
This is a plan of the general layout of a site with details. It is a necessary step for all construction projects, large or small. All existing features on the site need to be mapped. Also required are all planned changes, including floor plans of new construction. Items needed can include zoning, easements, utilities, setback lines, storm water drainage plans, and fire protection systems.

Grading Plans
 A drawing of a construction site showing existing and final design topography. This also includes the amounts of material to be cut, moved, or filled on the site during modifications. The proposed contours must often be designed in such ways as to prevent future erosion of ground material. This is often necessary when a large quantity of earth material is to be moved, a watershed or storm water drainage area is to be disrupted, or when existing and final ground surface level will vary more than an amount specified by the governing municipality.

Utility Design
Engineered design of utilities onsite and service hookup connections to main distribution lines. Our services include, but are not limited to electrical, water, and sanitary sewer system design. We know it is important not only that the system operates properly, but also the utility systems for your project are a perfect match for your needs. Our engineering staff is experienced in doing these utility designs on small and large scales, in both the private and public sectors.

Electrical Backbone Layout
 An electrical backbone layout is an electrical power distribution system.

Septic System Design
The WPES, Inc. engineering staff is well-qualified and experienced in designing septic systems, whatever the circumstance may be. Whether it is a (Smallest septic we engineer) or a commercial or residential development requiring a much larger system, we have no problem taking on your unique challenge.

Road & Street Design
Design of street and road systems for new and existing developments. When designing roads and streets, engineers must take special care to account for all details of the site and the project. Our engineering staff will cut no corners when working on transportation systems for your project. Projects requiring small bridges are no problem either, as our Professional Engineer is qualified to design them and has experience doing so.

Traffic Study
A traffic study is a detailed examination and analysis of a transportation system supported by data collection. A study starts with the identification and definition of a transportation problem, followed by data collection and analysis. A study is typically performed to explore a specific aspect of, or question about, a transportation system. Study results are usually summarized in a report.

Structural Design
Structural design is the methodical investigation of the stability, strength and rigidity of structures. The basic objective in structural analysis and design is to produce a structure capable of resisting all applied loads without failure during its intended life.

Geotechnical Investigation
-Loading capability, Footing and foundation design, Seismic analysis, Uplift
When it comes to foundations and footings, one size does not fit all. The size, shape, and purpose of the project are not the only factors that determine the qualities of the foundation. The soil underneath the project is also integral to reaching a proper and safe foundation and footing design. When this is needed, a WPES, Inc. engineer makes a visit to your site to dig material test pits and collect soil samples. Our engineers have many projects' worth of experience analyzing the soil layers found in the Columbia Basin. Typically, samples of specific soil strata are gathered and returned to our in-house materials testing facility to be analyzed. From this information, the loading capability of the ground at any site can be determined and the footings can then be appropriately designed for your specific situation.

Feasibility Study
This is a practical combination of many different aspects of engineering. At WPES, INC., we understand that proper planning today saves money tomorrow and want to help ensure that your investment is an efficient one. When doing a feasibility study, our staff look at all the aspects of your potential project and develop planned strategy as to what is be needed to help make it a successful venture. This allows the client to make an informed decision about their project. Our analysis estimates the costs associated with making the planned improvements to your site. We typically also look at some other sites, locations, and improvement plans for comparison. Included in our research are the costs of making the site functional for the planned future developments, such as changes to utilities, road infrastructure, and waste and pollution management.

Phase 1 Environmental Assessment
A Phase 1 Environmental Assessment is a study of a site intended to determine if there are any potential existing environmental hazards or concerns associated with the site. Anytime an acquisition of a large piece of property is made for industrial or commercial purposes, the completion of a Phase 1 Environmental Assessment will help limit the amount of liability the developer can incur. The process involves site visits by our staff members and extensive research into the history of the site and surrounding area. While doing this, we are looking for evidence of nearby hazardous waste and the statuses of any such locations. WPES, Inc. has been performing Phase 1 Environmental Assessments for more than 15 years. We are proud to say that during this time, no existing environmental issues beyond the scope of our original investigations have surfaced at any of these sites.

Phase 2 Environmental Assessment
In the event that hazards are found at a site during a phase 1 assessment, a developer or client would likely need to pursue a Phase 2 Assessment as a follow-up to determine how to deal with concerns found at the site.

Stormwater Pollution Prevention Plan
Stormwater runoff from construction sites can cause significant harm to our rivers, lakes, and coastal waters. A SWPPP is required (by your construction general permit) and will help you prevent stormwater pollution. A SWPPP is more than just a sediment and erosion control plan. It describes all the construction site operator’s activities to prevent stormwater contamination, control sedimentation and erosion, and comply with the requirements of the Clean Water Act.

Manufactured Home Inspection
When manufactured homes are sold, the Federal Home Association requires that the structural integrity of the home be inspected and signed off by a licensed engineer. This regularly involves inspecting the foundation underneath the home for proper supports. We are willing to inspect manufactured homes for structural integrity and soundness.
