Typically, the next step in the process is to apply for a permit to construct a sewage disposal system. A licensed designer will draw up a plan based on the site registration and your use of the property. The type of septic system will be either conventional or alternative depending on site conditions and use. Based on the number of bedrooms and/or water use the designer will draw a plan with septic tanks, pump tanks and drain field lines that are sufficient in size to support the use. The plan should include information such as well location, easements, utilities, dwelling size, dwelling dimensions, driveways, surface water, critical areas, and bluffs.

Based on the site characteristics the site may or may not be capable of supporting an on-site sewage disposal system. A typical Site Registration will provide a description of soil texture, soil depths, and water tables. The Site Evaluation does not expire and is acceptable so long as the findings remain valid. Certain activities such as grading, filling or logging of the property can alter the original findings and render the Site Registration invalid. The Site Registration (SR, Perc, etc.) is typically the first step in the process of obtaining permit(s). A Site Registration is a recorded document filed with Island County describing various conditions found on a site. A licensed designer is responsible for submitting the Site Registration.
