The first
step is to have a Septic System Feasibility Study performed on the property to determine if the site perks and if it does
what type system the Health District is going to require; This Study costs $ 250.00.
The next
step is to apply for and acquire approval of a “Critical Area’s Ordinance” site plan from the King County
Building Dept. They can do this for you if you desire, or you can hire your own consultant such as John Altmann with Altmann
Oliver Associates LLC 425-333-4535 john@altoliver.com or Kim Peterson
of Blue Heron Services 360-793-7767 bheron@premier1.net .
Note
for property located within a City's Limits, the CAO Review must still be done and approved by the City. A copy of the
letter from the City will need to be submitted with the Septic System Design Application to the Health District.
After
you have CAO approval for the site, then we can revisit the site and prepare the full septic system design and submit it to
the Health District for their review and approval; The Septic Design will cost
$ 1,500.00
(note that this amount is in addition to the $ 250.00 paid for the feasibility study; the design cannot be done without doing
the feasibility study first) with an additional Health District Design Review fee of between $ 455.00 – 1,026.00;
It will take us about a week to prepare the Septic Design; The Health
District will take between 10-16 weeks to review it; Once approved it will be valid for two years.
