The Complete Guide to Developing Property in Southwest Washington
Developing property is a process.
Whether you're building a commercial project, rural homesite, agricultural property, shop, or another type of development, successful construction starts with understanding the land and planning the infrastructure.
For property owners in Lewis County, Cowlitz County, and Southwest Washington, the following steps provide a general overview of the development process.
Step 1: Evaluate the Property
Start by understanding what you're working with.
Evaluate:
Zoning
Topography
Soil
Water
Septic
Access
Utilities
Critical areas
Wetlands
Drainage
Lewis County's Master Site Review is used for applicable development proposals to review zoning and critical-area requirements and identify required county, state, and federal permits.
Step 2: Develop the Site Plan
Once the constraints are understood, determine where everything will go.
This may include:
Buildings
Roads
Parking
Driveways
Septic
Wells
Utilities
Stormwater
Open space
Step 3: Complete Required Design and Permitting
Depending on the project, professional services may include:
Surveying
Civil engineering
Geotechnical engineering
Septic design
Environmental studies
Structural engineering
The applicable jurisdiction will determine what permits and approvals are required.
Step 4: Clear the Site
Once construction can proceed, the site may need to be cleared.
This can include:
Trees
Brush
Stumps
Existing structures
Pavement
Debris
Step 5: Establish Access
The project needs a reliable way for equipment and vehicles to enter the site.
That may involve:
Road approaches
Driveways
Private roads
Construction entrances
Culverts
Aggregate roads
Lewis County Public Works maintains road-development standards and related permit resources.
Step 6: Perform Mass Excavation
The property is then shaped to the required elevations.
This may include:
Cut
Fill
Export
Import
Stockpiling
Building-pad preparation
Step 7: Install Underground Utilities
Utilities may include:
Water
Sewer
Septic
Stormwater
Fire protection
Electrical
Communications
Step 8: Construct Roads and Parking
Once underground infrastructure and grading are coordinated, roads and parking areas can be constructed.
This may involve:
Subgrade preparation
Proof rolling
Grading
Aggregate base
Compaction
Step 9: Construct Stormwater Systems
Stormwater infrastructure can include:
Pipes
Catch basins
Manholes
Detention
Retention
Drainage structures
Washington's current Construction Stormwater General Permit applies to regulated construction activities and is effective January 1, 2026 through December 31, 2030.
Step 10: Prepare Foundations
Once the site is properly prepared, foundation excavation and preparation can begin.
The building pad and foundation area need to meet the project's plans and specifications.
Step 11: Complete Final Grading
After major construction, final grading establishes the finished site elevations.
This is where the property begins to look like the finished development.
Site Development Is a Team Effort
Successful development involves more than the excavation contractor.
Depending on the project, the team can include:
Owner
Contractor
Excavator
Engineer
Surveyor
Geotechnical professional
Septic designer
Utility providers
Inspectors
Building contractor
Other subcontractors
Good communication between these parties is critical.
Why Start With the Site?
The building may be the most visible part of a project, but the site is what supports it.
If the site has:
Poor drainage
Inadequate access
Improper grading
Utility conflicts
Unstable fill
Poorly prepared foundations
those issues can affect the entire development.
